The following description of at least one exemplary embodiment is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In a first embodiment, as shown in fig. 1 to 3, a stepped three-way switching valve includes a valve body having a valve cavity and a motor mounted on the valve body, the valve body is provided with a water inlet 101, a first water outlet 102 and a second water outlet 103 which are communicated with the valve cavity, a valve rod 11 is disposed in the valve cavity, the valve rod 11 is connected with the motor, the first water outlet 102 is located below the water inlet 101 and above the second water outlet 103, a sealing seat 12 is mounted in the valve cavity, the sealing seat 12 is provided with a hollow cavity which penetrates up and down, the upper end and the lower end of the hollow cavity are respectively communicated with the water inlet 101 and the second water outlet 103, an intermediate communication port 121 which enables the hollow cavity to be communicated with the first water outlet 102 is disposed in the middle of the sealing seat, an upper sealing port 122 and a lower sealing port 123 are disposed above and below the intermediate communication port 121 respectively, and the valve rod 11 is connected with a switching valve core assembly 13 which opens and closes the upper sealing port 122 and the lower sealing port 123.
The water inlet 101, the first water outlet 102 and the second water outlet 103 are sequentially arranged from top to bottom to form a stepped waterway switching structure, so that the height of the switching valve core assembly is reduced, and the valve body height is reduced. Of course, due to the adoption of the stepped waterway switching structure, the traditional valve core design cannot meet the use requirement, so that the sealing seat and the switching valve core assembly are optimally designed. Specifically, the inner diameter of the lower sealing port 123 is greater than that of the upper sealing port 122, the switching valve core assembly 13 includes a valve core 131, the valve core 131 is sequentially provided with a first sealing portion 1311, a second sealing portion 1312 and a third sealing portion 1313 from top to bottom, the first sealing portion 1311 and the second sealing portion 1313 are located above the lower sealing port 123, the third sealing portion 1313 is located below the lower sealing port 123, the second sealing portion 1312 and the third sealing portion 1313 are respectively used for sealing the upper port and the lower port of the lower sealing port 123, the first sealing portion 1311 is used for sealing the upper port of the upper sealing port 122, the diameters of the second sealing portion 1312 and the third sealing portion 1313 are identical, but may also be different, and need to be smaller than the diameters of the first sealing portion 1311, so as to correspond to the design that the inner diameter of the lower sealing port 123 is greater than the inner diameter of the upper sealing port 122. And sealing rings are arranged at the first sealing part 1311, the second sealing part 1312 and the third sealing part 1313 for realizing good sealing. The spool 131 has a spool chamber, and the spool 131 is provided with a spool port 1314 between the second seal 1312 and the third seal 1313, so that the spool chamber communicates with the spool outside. The valve rod 11 is provided with a lower fixed snap ring 113 below the valve core to drive the valve core 131 to move upwards, and the valve core 131 is connected with a reset spring 134 for resetting the valve core. The design that the inner diameter of the lower sealing port 123 is larger than that of the upper sealing port 122, and the positions and the diameters of the first sealing portion 1311, the second sealing portion 1312 and the third sealing portion 1313 are designed to correspond to the stepped waterway switching structure, so as to realize the three-way switching function.
As shown in fig. 4, when the valve stem 11 moves upward, the valve body 131 moves upward, and the third sealing portion 1313 of the valve body 131 seals the lower sealing port 123, and at this time, the intermediate communication port 121 on the sealing seat 12 is directly opposite to and communicates with the valve body port 1314, so that the water inlet 101 is communicated with the first water outlet 102. As shown in fig. 5, when the valve rod 11 moves downward, the valve core 131 moves downward, the first sealing portion 1311 seals the upper opening of the upper sealing port, the second sealing portion 1312 seals the upper opening of the lower sealing port, the middle communication port 121 and the valve core port 1314 are staggered up and down, the middle communication port 121 and the first water outlet 102 are closed, and the third sealing portion 1313 opens the lower opening of the lower sealing port, so that the water inlet 101 is communicated with the second water outlet 103 via the hollow cavity of the sealing seat and the valve core cavity. Thus, three-way switching of the three-way switching valve is achieved in the above manner.
The return spring 134 may realize the downward return of the valve cartridge 131. In order to install the return spring 134, as shown in fig. 2 and 3, the seal seat 12 is provided with a shaft fixing seat 132, the shaft fixing seat 132 is provided with a shaft hole for the valve rod 11 to pass through, the return spring 134 is arranged above the shaft fixing seat 132, the valve rod 11 is connected with an upper spring seat 133 above the return spring 134, and the valve rod 11 is connected with an upper fixing clamp ring 111 above the upper spring seat 133 for driving the upper spring seat 133 to move downwards. The shaft fixing seat 132 is positioned on the seal seat 12 and is elastically pressed by the return spring 134. The center of the shaft fixing seat 132 is provided with a central collar 1321, the center of which forms a shaft hole through which the valve rod 11 passes, and supporting ribs 1322 are radially distributed from the central collar 1321 to the radial outside. The upper end of the sealing seat is provided with a positioning groove 124, and the shaft fixing seat 132 is provided with a positioning part which is clamped into the positioning groove to realize the positioning between the shaft fixing seat 132 and the sealing seat 12. The positioning portions are end portions of the supporting ribs, and corresponding positioning grooves are uniformly distributed along the circumferential direction of the sealing seat, so that after the positioning portions are clamped into the positioning grooves, the shaft fixing seat is circumferentially positioned, and meanwhile, under elastic compression of the reset spring 134, the shaft fixing seat 132 is axially positioned.
In the above structure, the switching valve core assembly is integrally formed, the upper side is limited by the upper fixing clip 111, and the lower side is limited by the lower fixing clip 113, so that the valve core 131, the return spring 134, the upper spring seat 133, and the shaft fixing seat 132 can be integrally mounted and dismounted together with the valve rod 11. Of course, during installation, the sealing seat 12 needs to be installed before, and during disassembly, after the sealing seat 12 is disassembled, the whole sealing seat is disassembled, so that the structure is compact, and the installation and the disassembly are convenient.
Under the condition that the synchronous motor is used for driving the valve rod, the phenomenon of over-travel of the valve core can be caused due to uncontrollable travel of the synchronous motor, and the valve core is easy to over-travel and lose efficacy. To solve this problem, in an embodiment, the valve rod 11 is connected with an overload spring 136 above the bottom wall in the spool cavity, the valve rod 11 is connected with a lower spring seat 135 above the overload spring 136, and the valve rod 11 is connected with an intermediate fixed snap ring 112 above the lower spring seat 135 to drive the lower spring seat 135 to move downward. The excessive over travel is counteracted by compressing the overload spring 136, so that the protection function is realized when the valve core 131 exceeds the travel, and the phenomenon that the valve core 131 is out of operation due to the over travel is avoided. And the overload spring 136 is integrally positioned in the spool cavity, so that the integral height of the switching spool assembly is not increased, and the valve body height is reduced. It should be noted that, the lower spring seat 135 and the overload spring 136 are integrally installed and removed with the switching valve core assembly as a part of the switching valve core assembly due to the limitation of the middle fixed snap ring 112 and the inner bottom wall of the valve core cavity.
As shown in fig. 1 to 4, the valve body adopts a split type structure, and the split type valve body adopts a technical scheme that the valve body is composed of a first valve body 1 with a first valve cavity 10 and a second valve body 2 with a second valve cavity 20, wherein the water inlet 101, a first water outlet 102 and a second water outlet 103 are arranged on the first valve body 1, the first valve body 1 is provided with a first interface 14 at the first water outlet 102, the second valve body 2 is provided with a second interface 21, the first interface 14 is fixedly and hermetically connected with the second interface 21, the first valve cavity 10 is communicated with the second valve cavity 20 through the first water outlet 102, and a water outlet flow channel 201 communicated with the second valve cavity is arranged on the second valve body 2.
The first port 14 and the second port 21 are fixed by a buckle and sealed by a sealing ring 141, so as to ensure that the first valve body 1 and the second valve body 2 become a firm whole and avoid leakage between the first port 14 and the second port 21.
In this embodiment, the structure of fastening and fixing preferably includes a clamping slot provided on one of the first interface 14 and the second interface 21, and a clamping hook provided on the other, where the clamping hook is clamped into the clamping slot, or a clamp 211 may be further provided outside the butt joint of the first interface 14 and the second interface 21. Of course, it will be appreciated by those skilled in the art that other means of snap-fit fixation may be used between the first interface 14 and the second interface 21. For example, a first clamping protrusion is provided on the outer edge of the first interface 14, and a second clamping protrusion is provided on the outer edge of the second interface 21, and the first clamping protrusion and the second clamping protrusion are abutted and clamped together by using the clamp 211. Or the first interface 14 and the second interface 21 are fixed in a threaded manner.
When the first interface 14 and the second interface 21 are fixed by clamping, the first interface and the second interface can be positioned to avoid circumferential dislocation. For example, one of the first interface and the second interface is provided with a positioning groove, and the other one is provided with a positioning boss.
As a structure on the plate change water outlet valve, the heating water outlet, the bathroom water outlet and the plate change connection port are arranged in a conventional manner, in this embodiment, the heating water outlet, the bathroom water outlet and the plate change connection port are arranged on the second valve body, and the water outlet of the first water outlet 102 enters the second valve cavity 20 and can be communicated with the corresponding interfaces through the heating water outlet, the bathroom water outlet and the plate change connection port.
The second embodiment is different from the first embodiment in that a valve body of a unitary structure, i.e., a first valve body and a second valve body of one embodiment are integrated, as shown in fig. 6. In the first embodiment, the water outlet channel 201 is vertically disposed, and in the present embodiment, the water outlet channel 201 is diagonally disposed. As can be seen from comparing the first embodiment with the second embodiment, the valve body with the split structure can not only reduce the processing difficulty of the valve body and ensure the processing quality, but also overcome the obstacle of the integrated valve body. Obviously, in the split valve body, the water outlet flow channel 201 adopts vertical arrangement, and compared with the water outlet flow channel which is obliquely arranged, the space of the valve body can be saved.
In the present invention, the terms "upper" and "lower" are used only to describe the orientation or positional relationship, and the states shown in the drawings are merely illustrative of the distinction between the specific components, and thus should not be construed as limiting the present invention.
In addition to the above preferred embodiments, the present invention has other embodiments, and various changes and modifications may be made by those skilled in the art without departing from the spirit of the invention, which shall fall within the scope of the invention as defined in the appended claims.
