As shown in Figure 1, the cock type three-way valve of the embodiment of the invention one, comprise valve body 1 and the coaxial valve core 2 that is installed in valve body 1 chamber, by the interior valve gap 3 that cooperates with valve body 1 inwall screw top and the chamber of valve body 1 is airtight by the outer valve gap 4 of bolton on valve body 1, rotating shaft 6 is coaxial be installed on the valve core 2 and from interior valve gap 3 and outside valve gap 4 pass, rotating shaft 6 cooperates with interior valve gap 3 and outer valve gap 4 liquid sealings, and handle 5 is installed in the end that rotating shaft 6 passes.Said structure also can adopt the structure of other existing stopcock to replace.
As shown in Figure 2, valve body 1 is provided with the mouth of pipe 11, the near-end mouth of pipe 2,13 3 interface tubes of the far-end mouth of pipe; On the axial of valve body 1, the interface tube inwall is the corresponding mouth of pipe circular arc of difference, near-end mouth of pipe circular arc, far-end mouth of pipe circular arc between the end points on the valve body 1 chamber wall, and the interior circular arc of corresponding valve body 1 between the adjacent end points of adjacent tubes interface, the external arc at a distance of corresponding valve body 1 between the most distal point of adjacent tubes interface; Valve core 2 peripheral intervals are provided with nearly groove 24 and groove 22 far away, and long sealing surface 21 between groove 22 far away and the nearly groove 24 and short sealing surface 23, groove 22 far away and the nearly groove 24 formation connecting passage that communicates in valve core 2 inside, with valve core 2 rotations, by at least two interface tubes of at least one sealing surface sealing; Or, be communicated with the mouth of pipe 11 and the far-end mouth of pipe 13 by connecting passage by arbitrary sealing surface closed proximal end mouth of pipe 12; Or, be communicated with two interface tubes in addition by connecting passage by the long sealing surface 21 sealing mouth of pipe 11 or the far-end mouths of pipe 13; Or long sealing surface 21 is between the mouth of pipe 11 and the far-end mouth of pipe 13, and short sealing surface 23 is positioned near the near-end mouth of pipe 12, is communicated with three interface tubes by connecting passage.
The mouth of pipe 11 promptly is respectively the interface tube of largest axis angle and minimum axis angle with left and right sides adjacent tubes interface axis angle, the far-end mouth of pipe 13 promptly with the interface tube of the mouth of pipe 11 axis angle maximums, the near-end mouth of pipe 12 promptly with the interface tube of the mouth of pipe 11 axis angle minimums.
Imperial palace circular arc, maximum external arc are between the adjacent inwall end points of two interface tubes of axis angle maximum, at a distance of the circular arc between the inwall end points farthest, and the like, between inferior big correspondence time big axis angle two interface tubes, between minimum corresponding minimum axis angle two interface tubes.
With valve core 2 rotations, long sealing surface 21 is between the mouth of pipe 11 and the far-end mouth of pipe 13 time, long sealing surface 21 arc length are less than maximum external arc, the mouth of pipe 11 and the far-end mouth of pipe 13 are communicated with by connecting passage, short sealing surface 23 is positioned near the near-end mouth of pipe 12, and short sealing surface 23 arc length can be passed through the short sealing surface 23 closed proximal end mouths of pipe 12 greater than near-end mouth of pipe circular arc, so the mouth of pipe 11 and 13 connections of the far-end mouth of pipe; Nearly groove 24 arc length are greater than inferior imperial palace circular arc, inevitable also greater than circular arc in minimum, therefore counterclockwise rotate valve core 2 along Fig. 2, be communicated with the mouth of pipe 11 and the near-end mouth of pipe 12 by nearly groove 24, long sealing surface 21 arc length are less than maximum external arc, long sealing surface 21 and groove 22 arc length sums far away are greater than imperial palace circular arc and mouth of pipe circular arc sum, by the groove 22 connection far-end mouths of pipe 13 far away, thereby realize the connection of three interface tubes.
Long sealing surface 21 arc length are greater than mouth of pipe circular arc, therefore when long sealing surface 21 just seals the mouth of pipe 11, nearly groove 24 is greater than inferior imperial palace circular arc, the near-end mouth of pipe 12 is communicated with nearly groove 24, long sealing surface 21 arc length are less than maximum external arc, long sealing surface 21 and groove 22 arc length sums far away are greater than imperial palace circular arc and mouth of pipe circular arc sum, the far-end mouth of pipe 13 is communicated with groove 22 far away, the near-end mouth of pipe 12 and the far-end mouth of pipe 13 are communicated with by connecting passage, and short sealing surface 23 is between the far-end mouth of pipe 13 and the near-end mouth of pipe 12; Long sealing surface 21 arc length are greater than far-end mouth of pipe circular arc, so long sealing surface 21 closed distal end mouths of pipe 13, when the near-end mouth of pipe 12 is communicated with groove 22 far away, short sealing surface 23 is less than minimum external arc, guaranteed that the mouth of pipe 11 is communicated with nearly groove 24, thereby realize the connection of the mouth of pipe 11 and the near-end mouth of pipe 12, short sealing surface 23 is between the mouth of pipe 11 and the near-end mouth of pipe 12; Nearly groove 24 is greater than inferior imperial palace circular arc, and therefore by the long sealing surface 21 sealing mouths of pipe 11, the near-end mouth of pipe 12 and the far-end mouth of pipe 13 can be communicated with by nearly groove 24, and this moment, short sealing surface 23 was between the mouth of pipe 11 and the far-end mouth of pipe 13.
Therefore long sealing surface 21 arc length are less than maximum external arc, greater than mouth of pipe circular arc, far-end mouth of pipe circular arc; Short sealing surface 23 arc length are greater than near-end mouth of pipe circular arc, less than minimum external arc; Long sealing surface 21 and groove 22 arc length sums far away are greater than imperial palace circular arc and mouth of pipe circular arc sum, and nearly groove 24 arc length can guarantee three interface tube intercommunications and connection in twos greater than inferior imperial palace circular arc.Short sealing surface 23 arc length also can realize the sealing of the near-end mouth of pipe 12 when equaling near-end mouth of pipe circular arc, but are subjected to the influence of foozle easily, influence sealing effect.
In order to further facilitate the use of valve, the position that increases by three interface tube intercommunications of valve and be communicated with in twos.Long sealing surface 21 and nearly groove 24 arc length sums are greater than imperial palace circular arc and far-end mouth of pipe circular arc sum, and far groove 22 is greater than inferior imperial palace circular arc.
Therefore work as long sealing surface 21 between the mouth of pipe 11 and the far-end mouth of pipe 13, during by the weak point sealing surface 23 closed proximal end mouths of pipe 12, rotate valve core 2 along Fig. 2 clockwise direction, groove 22 far away is greater than inferior imperial palace circular arc, be communicated with the far-end mouth of pipe 13 and the near-end mouth of pipe 12 by groove 22 far away, long sealing surface 21 arc length are less than maximum external arc, long sealing surface 21 and nearly groove 24 arc length sums are greater than imperial palace circular arc and far-end mouth of pipe circular arc sum, be communicated with the mouth of pipe 11 by nearly groove 24, thereby realize the connection of three interface tubes.Long sealing surface 21 arc length are greater than far-end mouth of pipe circular arc, therefore when long sealing surface 21 just during the closed distal end mouth of pipe 13, groove 22 far away is greater than inferior imperial palace circular arc, the near-end mouth of pipe 12 is communicated with groove 22 far away, long sealing surface 21 arc length are less than maximum external arc, long sealing surface 21 and nearly groove 24 arc length sums are greater than imperial palace circular arc and far-end mouth of pipe circular arc sum, the mouth of pipe 11 is communicated with nearly groove 24, the near-end mouth of pipe 12 and the mouth of pipe 11 are communicated with by connecting passage, and short sealing surface 23 is between the mouth of pipe 11 and the near-end mouth of pipe 12; And long sealing surface 21 arc length are greater than mouth of pipe circular arc, the therefore long sealing surface 21 sealing mouths of pipe 11, when the near-end mouth of pipe 12 is communicated with nearly groove 24, groove 22 far away is greater than inferior imperial palace circular arc, long sealing surface 21 and nearly groove 24 arc length sums are greater than imperial palace circular arc and far-end mouth of pipe circular arc sum, whole circumference deducts imperial palace circular arc, far-end mouth of pipe circular arc, be minimum external arc behind the inferior imperial palace circular arc, therefore guarantee also that short sealing surface 23 is less than minimum external arc, also inevitable less than inferior big external arc, guaranteed that the far-end mouth of pipe 13 is communicated with groove 22 far away, thereby realize the connection of the far-end mouth of pipe 13 and the near-end mouth of pipe 12, short sealing surface 23 is between the far-end mouth of pipe 13 and the near-end mouth of pipe 12; Groove 22 far away is greater than inferior imperial palace circular arc, and therefore by the long sealing surface 21 closed distal end mouths of pipe 13, the near-end mouth of pipe 12 and the mouth of pipe 11 can be communicated with by groove 22 far away, and this moment, short sealing surface 23 was between the mouth of pipe 11 and the far-end mouth of pipe 13.
At short sealing surface 23 during less than minimum external arc, long sealing surface 21 and groove 22 arc length sums far away are greater than imperial palace circular arc and mouth of pipe circular arc sum, and closely groove 24 arc length are greater than inferior imperial palace circular arc; Long sealing surface 21 and nearly groove 24 arc length sums are greater than imperial palace circular arc and far-end mouth of pipe circular arc sum, groove 22 far away is greater than inferior imperial palace circular arc, both need only satisfy one of them promptly can satisfy the near-end mouth of pipe 12 respectively with being communicated with of the mouth of pipe 11 and the far-end mouth of pipe 13, the connection of three interface tubes, be set to satisfy simultaneously when having guaranteed that three's intercommunication realizes on two sense of rotation, increased the position of connected state in twos.Can certainly be set to nearly groove 24 arc length greater than circular arc in minimum, groove 22 far away is greater than inferior imperial palace circular arc, satisfying on the basis that communicates in twos, can satisfy three's intercommunication requirement on two sense of rotation, perhaps other satisfy one of them form greater than inferior imperial palace circular arc.
In order further to increase the connection position of a mouth of pipe 11 and the far-end mouth of pipe 13, long sealing surface 21 arc length are greater than near-end mouth of pipe circular arc, therefore can pass through the long sealing surface 21 closed proximal end mouths of pipe, deduct imperial palace circular arc less than 360 degree, avoid long sealing surface 21 to seal three interface tubes simultaneously, the mouth of pipe 11 and the far-end mouth of pipe 13 are communicated with by connecting passage.Can certainly only select in the connection position of above-mentioned two mouths of pipe 11 and the far-end mouth of pipe 13.
If short sealing surface 23 arc length equal mouth of pipe circular arc, then can be by the short sealing surface 23 sealing mouths of pipe 11, nearly groove 24 arc length equal imperial palace circular arc, long sealing surface 21 and nearly groove 24 arc length sums are greater than imperial palace circular arc and far-end mouth of pipe circular arc sum, then can pass through the long sealing surface 21 closed distal end mouths of pipe 13, carry out closing of valve, therefore short sealing surface 23 arc length are greater than mouth of pipe circular arc, nearly groove 24 arc length can guarantee closing of valve less than imperial palace circular arc.
In like manner, if short sealing surface 23 arc length equal far-end mouth of pipe circular arc, then can be by the short sealing surface 23 closed distal end mouths of pipe 13, groove 22 arc length far away equal imperial palace circular arc, and long sealing surface 21 and groove 24 arc length sums far away then can be passed through long sealing surface 21 to seal the mouths of pipe 11 greater than imperial palace circular arc and mouth of pipe circular arc sum, carry out closing of valve, therefore short sealing surface 23 arc length are greater than far-end mouth of pipe circular arc, and groove 22 arc length far away can guarantee closing of valve less than imperial palace circular arc.
Here short sealing surface 23, nearly groove 24, groove 22 far away also can be got separately or together and equal can realize closing of valve equally, but be subjected to the influence of foozle to cause poor sealing easily.This borough chief's sealing surface 21 can not be got to open simultaneously simultaneously for two interface tubes that prevent to seal in fact and close, thereby hinders the realization communicate in twos, but when lack sealing surface 23 get greater than the time, long sealing surface 21 also can be got and equal.
Long sealing surface 21 arc length be provided with greater than minimum external arc, can seal closing of the mouth of pipe 11 and the near-end mouth of pipe 12 realization valves simultaneously by long sealing surface 21, can certainly get and equal minimum external arc.
With the requirement of satisfying three kinds of closed conditions that valve is provided with, be the position of closing in order to increase, with convenient each functional area is separated.Certainly can also realize closing of valves by long 21 while of the sealing surface closed distal end mouth of pipe 13 and the near-end mouth of pipe 12, close closing of the near-end mouth of pipe 12 and the mouth of pipe 11 or the near-end mouth of pipe 12 and the far-end mouth of pipe 13 realization valves respectively by two sealing surfaces, seal three interface tubes simultaneously by long sealing surface 21, can certainly only select to close in above-mentioned three kinds in the mode one or both.
In a general right-angle tee stopcock, the diameter ratio of interface tube and valve body 1 chamber is 2 to 5, and mouth of pipe circular arc, near-end mouth of pipe circular arc, far-end mouth of pipe circular arc equate that its corresponding central angle all is 47 degree; Axis angle between the mouth of pipe 11 and the near-end mouth of pipe 12 is 90 degree, and the axis angle between the mouth of pipe 11 and the far-end mouth of pipe 13 is 180 degree.Therefore, the scope that valve core 2 each parts of periphery allow is as follows: the central angle of the corresponding valve core 2 of long sealing surface 21 arc length is about 137～227 degree, be minimum external arc between the maximum external arc,, therefore also satisfy 360 degree simultaneously and deduct imperial palace circular arc because the largest axis angle is 180 degree; The central angle of the corresponding valve core 2 of short sealing surface 23 arc length is about 47～137 degree, and promptly the maximum value in mouth of pipe circular arc, near-end mouth of pipe circular arc, the far-end mouth of pipe circular arc is between the minimum external arc; The central angle of nearly groove 24 arc length and the corresponding valve core 2 of groove 22 arc length far away is about 43～133 degree, promptly when time imperial palace circular arc and the imperial palace circular arc.And groove 22 far away, long sealing surface 21 sums are greater than 180 degree, and nearly groove 24, long sealing surface 21 sums are greater than 180 degree.
In the present embodiment, the central angle of the concrete corresponding valve core 2 of long sealing surface 21 arc length is 140 degree; The central angle of the corresponding valve core 2 of short sealing surface 23 arc length is 52 degree; The central angle of nearly groove 24 arc length and the corresponding valve core 2 of groove 22 arc length far away is 84 degree, all is 224 degree with long sealing surface 21 arc length sums respectively.
In the present embodiment, the far-end mouth of pipe 13 links to each other with water-heater water tank, and the near-end mouth of pipe 12 is for cold water comes water, the mouth of pipe 11 water outlets.As shown in Figure 3, from left to right first row be followed successively by close, full open cold water, hot and cold water mixings, full open hot water, hot and cold water mix, the moisturizing of full open water-heater water tank, second arrange be successively close, semi-open water-heater water tank moisturizing, close, full open hot water, close, semi-open cold water.Therefore can realize that simultaneously cold water water supply, water tank moisturizing, hot water supply water, hot and cold water mixes by a valve, satisfy all application demands, simplify the design and installation of pipeline, make things convenient for use.
Operation for convenience, selecting among Fig. 3 first valve core 2 positions that ranked first is initial position, by carrying out function distinguishing with turning clockwise counterclockwise, when valve core 2 turns clockwise, can be earlier continue rotation again after with water tank emptying and carry out moisturizing by all hot water, when valve core 2 is rotated counterclockwise, be followed successively by full cold water, hot and cold water mixing, all hot water.Certainly valve core 2 also can circulate to rotate and add label manner on valve gap and operate.
Embodiment two:
Can full open when further guaranteeing that three interface tubes communicate in twos, above-mentioned minimum external arc deducts maximum external arc less than imperial palace circular arc and 360 degree, long sealing surface 21 arc length deduct maximum external arc less than imperial palace circular arc and 360 degree, can realize that the full open of the mouth of pipe 11 and the far-end mouth of pipe 13 is communicated with.Above-mentioned mouth of pipe circular arc, near-end mouth of pipe circular arc, far-end mouth of pipe circular arc are less than circular arc in minimum, short sealing surface 23 arc length are less than circular arc in minimum, can realize that the near-end mouth of pipe 12 is communicated with the full open of the mouth of pipe 11 and the far-end mouth of pipe 13 respectively, and avoided the full open connected sum close between possible contradiction.Certainly all here less than getting the identical effect that also can get when equaling.
Be than different that with one of embodiment the diameter ratio of the interface tube of present embodiment and valve body 1 chamber is 1 to 5, mouth of pipe circular arc, near-end mouth of pipe circular arc, far-end mouth of pipe circular arc equate that its corresponding central angle all is 23 degree, and the axis angle between the interface tube is identical; Therefore imperial palace circular arc is that 157 degree are spent greater than minimum external arc 113, and minimum interior circular arc is that 67 degree are greater than mouth of pipe circular arc, near-end mouth of pipe circular arc, far-end mouth of pipe circular arc.Therefore, the scope that each parts of valve core 2 periphery allow is as follows: the central angle of the corresponding valve core 2 of long sealing surface 21 arc length is about 113～157 degree, and promptly minimum external arc arrives between the imperial palace circular arc; The central angle of the corresponding valve core 2 of weak point sealing surface 23 arc length is about 23～67 degree, and promptly the maximum value in mouth of pipe circular arc, near-end mouth of pipe circular arc, the far-end mouth of pipe circular arc is between the minimum interior circular arc; The central angle of nearly groove 24 arc length and the corresponding valve core 2 of groove 22 arc length far away is about 67～157 degree, promptly between time imperial palace circular arc and the imperial palace circular arc.And groove 22 far away, long sealing surface 21 three's sums are greater than 180 degree, and nearly groove 24, long sealing surface 21 three's sums are greater than 180 degree.
As shown in Figure 4, in the present embodiment, the central angle of the corresponding valve core 2 of concrete long sealing surface 21 arc length is 140 degree; The central angle of the corresponding valve core 2 of short sealing surface 23 arc length is 52 degree; The central angle of nearly groove 24 arc length and the corresponding valve core 2 of groove 22 arc length far away is 84 degree, is 180 degree with long sealing surface 23 arc length sums respectively.
