Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The all other embodiment obtained, belong to the scope of the utility model protection.
As depicted in figs. 1 and 2, a kind of pipe fitting for controlling water (flow) direction, including body 1 and cock body 3 are present embodiments provided,
The cock body 3 has heavy caliber end 5 and small-caliber end 7, and the heavy caliber end 5 of the cock body 3 is bonded admittedly with the madial wall of body 1
Fixed, the external diameter of the small-caliber end 7 of the cock body 3 is less than the internal diameter of body 1, and its end is opening-closing structure, the osculum of the cock body 3
The internal diameter at footpath end 7 is tapered along heavy caliber end 5 to the direction of small-caliber end 7.Preferably, the heavy caliber end 7 of cock body 3 and small-caliber end 7
It is arranged in body 1.
The operation principle of the pipe fitting of the control water (flow) direction is as follows：
The heavy caliber end 5 of cock body 3 is used as water inlet end, and small-caliber end 7 is used as water side, and current are from the heavy caliber end 5 of cock body 3
It is flowed into cock body 3, the opening-closing structure of the small-caliber end 7 of cock body 3 is produced the dynamic of a unlatching by the pressure of current in cock body 3
Make, current can pass through from opening-closing structure；And when flow reversal is flowed（I.e. current are from the small-caliber end 7 of cock body 3 to heavy caliber end
5 flowings）When, as shown in figures 2 and 5, the space that current are flowed between body 1 and cock body 3, water flow pressure causes the osculum of cock body 3
The opening-closing structure closing at footpath end 7, current cannot be introduced into inside cock body 3, so as to reach the effect of reverse sealing, and water flow pressure
Bigger, reverse water-stagnating effect is more notable.It can control current can only by the pipe fitting for installing control water (flow) direction of the present utility model
This direction of small-caliber end 7 flowing from the heavy caliber end 5 of cock body 3 to cock body 3, realize the purpose of control water (flow) direction.
The embodiment of optimization, as shown in Figure 3 and Figure 4, have between the heavy caliber end 5 of the cock body 3 and small-caliber end 7
Cause reverse current to cock body 3 along heavy caliber end 5 to the tapered changeover portion 6 of the direction bore of small-caliber end 7, the setting of changeover portion 6
A radial forces are produced, so as to increase the closure effect of the small-caliber end 7 of cock body 3 when flow reversal is flowed, improve this
Control the reverse water-stagnating effect of the pipe fitting of water (flow) direction.Further, the changeover portion 6 of the cock body 3 has two planes, two
The plane is with the setting substantially symmetrical about its central axis of cock body 3, and the tapered direction of bore of the plane along changeover portion 3 is obliquely installed；Institute
The outer surface for stating the small-caliber end 7 of cock body 3 is plane.Stress surface between cock body 3 and reverse current is designed as planar structure,
The closure effect of the opening-closing structure of cock body 3 is improved, so as to more effectively prevent flow reversal from flowing.
In addition, in order to avoid cock body 3 is moved under the pressure effect of current, and weaken folding of the current to cock body 3
The pressure of structure, between cock body 3 and body 1 a kind of fixed embodiment as shown in Figure 3 and Figure 4, the heavy caliber of the cock body 3
The fixed block 4 of one ring-type of the connection of end 7, the internal diameter of the fixed block 4 is consistent with the internal diameter at the heavy caliber end 5 of cock body 3, the fixation
The external diameter of block 4 is more than the internal diameter of body 1.When cock body 3 is arranged on 1 inside of body, cock body 3 is fastened on the end of body 1 by fixed block 4
Portion, when current produce pressure effect inside cock body 3 to the opening-closing structure of cock body 3, pass through the work between fixed block 4 and body 1
Firmly so that cock body 3 will not move under water flow pressure effect in the interior edge water (flow) direction of body 1.Further, the cock body 3
It is made with fixed block 4 using silica gel material, silica gel material cost is low, and silica gel is flexible so that the opening-closing structure of cock body 3 exists
Smoothly it can be opened and be closed under water flow pressure effect；As shown in figure 4, the cock body 3 and fixed block 4 are integrally formed, keep away
Exempt from gap be present between cock body 3 and fixed block 4, influence fixation of the cock body 3 in body 1.
Fixed another embodiment can also be by the heavy caliber end 5 of cock body 3 and body 1 between cock body 3 and body 1
It is threadably secured between side wall.
In addition, for the ease of the pipe fitting of this control water (flow) direction that is provided in the present embodiment can quickly smoothly with outside
Pipeline is attached, as shown in figure 1, the both ends of the body 1 are respectively connected with snap joint 2, facilitates the pipe by snap joint 2
The Fast Installation of body 1 and external water pipe is in dismounting.
In summary, the pipe fitting of this control water (flow) direction provided by the utility model is designed using funnelform cock body,
When forward direction connects current, water flow pressure washes the closed mouth of the opening-closing structure of cock body open, and then water will pass through cock body, reverse current
When, because bell mouth uses taper, water flow pressure is produced on the conical surface, water flow pressure seals the opening-closing structure of cock body, to reach
The effect of reverse sealing, simple in construction, small volume, and cost is low.
Exemplified as above is only for example, not forming to the scope of protection of the utility model to of the present utility model
Limitation, it is every to be belonged to the same or analogous design of the utility model within the scope of protection of the utility model.
