Description

Technical Field

[0001] The present application relates to the field of valves, and in particular to a valve installation structure. Background Art

[0002] The heat pump system is a highly efficient and energy-saving heating and cooling equipment. Its working principle is based on the principle of thermodynamics. It achieves heat transfer by consuming a small amount of electrical energy or thermal energy, thereby meeting the heating and cooling needs in people's lives and production. Ball stop valves and other types are also widely used in heat pump systems. They cut off or adjust the flow of the medium by rotating the ball or valve stem.

[0003] The valve body and valve cover of the ball valve used in the existing heat pump system are connected and fixed with bolts. However, due to the influence of the use environment, the bolts will rust, which will cause rust at the threaded connection, making it difficult to disassemble the valve body during maintenance. At the same time, the connection between the bolts and nuts will also increase the disassembly time, resulting in low maintenance efficiency. Utility Model Content

[0004] In order to improve the problem that the spherical stop valve used in the heat pump system is inconvenient to maintain, the present application provides a valve installation structure.

[0005] A valve installation structure provided in this application adopts the following technical solution:

[0006] A valve installation structure includes a valve cover fixedly installed on the top of a valve body, a plurality of fixed components are arranged around the valve cover, the plurality of fixed components include a push block fixedly installed on the lower end of a push rod for propping up an elastic core shaft, and a limit component is provided on the surface of the push rod.

[0007] The limiting assembly comprises a right-angled triangular clamping block which is slidably mounted on one side of the upper surface of the push rod and is used for clamping in the clamping groove.

[0008] When the right-angled triangle block is inserted into the slot on the lower side of the valve cover, the push block squeezes the elastic core shaft and is inserted and fixed in the cavity to fix the valve body and the valve cover. A cavity for inserting the elastic core shaft is arranged around the inside of the valve body. The cavity is arranged in an "eight" shape. The push block is arranged in an inverted cone shape. A sleeve fixed to the elastic core shaft is fixed at a position corresponding to the cavity at the lower end of the valve cover. The contact position between the inner wall of the elastic core shaft and the surface of the push block is arranged as a protrusion so that the lower end of the elastic core shaft has an umbrella-like tendency to spread out.

[0009] By adopting the above technical solution and the structural design of multiple fixing components, the valve body and the valve cover can be quickly installed and disassembled, and the connection parts can be prevented from being unable to be disassembled due to rust.

[0010] Preferably, the two sockets are fixedly connected to the bottom of the valve cover, and a slide groove one adapted to the shape of the push block is opened at the bottom of the socket. The push block is located in the slide groove one and realizes longitudinal sliding. The top of the push rod moves through the socket and the side wall of the valve cover in turn and is fixedly connected with a handle.

[0011] By adopting the above technical solution, the push rod is pushed by the handle, and the push rod drives the push block fixed at the bottom end thereof to slide down in the slide groove 1, thereby expanding the elastic core shaft.

[0012] Preferably, a slot matching the shape of the socket is provided on the top of the valve body, the socket is movably inserted in the inner cavity of the slot, a cavity connected to the slot is provided below the slot inside the valve body, and the inner wall of the cavity abuts against the surface of the elastic core shaft in the expanded state.

[0013] By adopting the above technical scheme, the sleeve and the elastic core shaft are inserted into the slot and the cavity, and the push rod is pushed. The push rod drives the push block fixed at its bottom end to slide down in the slide groove, and the elastic core shaft is stretched open. At this time, the inner wall of the cavity abuts against the surface of the elastic core shaft to avoid the generation of a void. The inner wall of the cavity and the surface of the elastic core shaft generate friction. Under the action of the friction force, the elastic core shaft is fixed in the cavity, and the sleeve is fixed in the slot at the same time, thereby realizing the function of quickly installing and disassembling the valve cover and the valve body.

[0014] Preferably, the push rod surface is provided with a second slide groove that is compatible with the shape of the right-angled triangle block, the right-angled triangle block is located in the second slide groove and can slide horizontally, and the side of the right-angled triangle block is fixed with a spring whose other end is fixed to one side of the inner cavity of the second slide groove.

[0015] By adopting the above technical solution, the push rod is pushed downward, and the right-angled triangle block engaged in the upper groove is forced to slide into the second slide groove, and at the same time, the push rod drives the push block to move downward to open the elastic core shaft. When the elastic core shaft is opened by the push block until its surface abuts against the inner wall of the cavity, the right-angled triangle block just slides to the position corresponding to the lower groove. At this time, under the action of the spring, the right-angled triangle block is engaged in the groove, and the bottom of the handle is fitted with the top of the valve body, so that the push rod is limited at this position, and the push block is limited at this position, so that the surface of the elastic core shaft is always in contact with the inner wall of the cavity, preventing the sleeve and the elastic core shaft from slipping out of the slot and the cavity.

[0016] Preferably, there are two clamping grooves and both are located inside the valve cover.

[0017] By adopting the above technical solution, when the right-angled triangle block is engaged in the slot on the upper side, the elastic core shaft is not stretched open, and the sleeve and the elastic core shaft can be pulled out from the slot and the cavity; when the right-angled triangle block is engaged in the slot on the lower side, the elastic core shaft is stretched open by the protrusion and the surface of the elastic core shaft is always in contact with the inner wall of the cavity, preventing the sleeve and the elastic core shaft from slipping out of the slot and the cavity.

[0018] Preferably, an L-shaped lever is fixedly connected to the side of the right-angled triangle block, and a sliding groove three matching the shape of the L-shaped lever is provided on the push rod and the top of the handle, and the L-shaped lever is located in the sliding groove three and slides horizontally.

[0019] By adopting the above technical solution, the L-shaped lever is pushed, and the L-shaped lever slides in the third slide groove, driving the right-angled triangle block to slide into the second slide groove, so that the push rod can drive the push block to slide upward, and then the elastic core shaft is no longer stretched, and the sleeve and the elastic core shaft are no longer fixed in the slot and the cavity, and then the valve cover can be removed from the valve body, and the disassembly is simple and convenient.

[0020] Preferably, the top end of the L-shaped lever passes through the sliding groove three and then extends to the outside, and a space for the L-shaped lever to move horizontally is reserved between the longitudinal rod of the L-shaped lever and the sliding groove three.

[0021] By adopting the above technical solution, the top of the L-shaped lever is extended to the outside for easy shifting.

[0022] Preferably, a sealing ring for sealing is provided between the upper end surface of the valve body and the lower end surface of the valve cover.

[0023] By adopting the above technical solution, the sealing performance of the connection between the valve cover and the valve body is increased under the action of the sealing ring.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. By setting up multiple groups of fixing components, the valve cover and the valve body can be quickly disassembled and installed. It is only necessary to use tools or manually push the L-shaped lever to move, drive the right-angled triangle block to separate from the slot, and then the push rod and the push block can be moved out from the inside of the valve body, thereby achieving the disassembly effect. The operation is simple and the disassembly can be achieved in one step, which effectively saves maintenance time. At the same time, the gap between the L-shaped lever and the slide groove three can be filled with a rubber plug to achieve sealing, thereby preventing impurities from entering the slide groove three and affecting the subsequent sliding of the L-shaped lever.

[0040] The contact position between the inner wall of the elastic core shaft 39 and the surface of the push block 35 is set as a protrusion so that the lower end of the elastic core shaft 39 has an umbrella-like tendency to spread out, and a space for the L-shaped lever 335 to move horizontally is reserved between the longitudinal rod of the L-shaped lever 335 and the third slide groove 336.

[0041] The limiting assembly 33 is arranged on the left side of the push rod 31 surface. The limiting assembly 33 includes a right-angled triangle block 331. A second slide groove 333 matching the shape of the right-angled triangle block 331 is opened on the left side of the push rod 31 surface. The right-angled triangle block 331 is slidably installed in the second slide groove 333. A spring 332 is fixedly connected to the center of the inner side of the right-angled triangle block 331. One end of the spring 332 away from the right-angled triangle block 331 is fixedly connected to the center of the inner side of the groove cavity of the second slide groove 333. The center of one side of the right-angled triangle block 331 fixedly connected to the spring 332 is fixedly connected to the L shaped lever 335, one end of the L-shaped lever 335 away from the right-angled triangle block 331 movably passes through the side walls of the push rod 31 and the handle 32 and extends to the outside, a sliding groove three 336 matching the shape of the L-shaped lever 335 is opened at the top of the push rod 31 and the handle 32, and the push rod 31 is divided into two parts with the sliding groove three 336 as the dividing line, and the two parts are fixed by screws to facilitate the installation of the L-shaped lever 335, and two slots 334 matching the shape of the right-angled triangle block 331 are opened at the position of the right-angled triangle block 331 on the left side of the inner cavity of the sliding groove five 311

[0042] During installation, the insert sleeve 34 at the bottom of the valve cover 2 is aligned with the elastic core shaft 39 in the slot 36, and the elastic core shaft 39 and the insert sleeve 34 are completely inserted into the cavity 37 and the slot 36. Then, the push rod 31 is pushed by the handle 32, and the push rod 31 slides down in the slide groove 4 310 and the slide groove 5 311, and then the push block 35 fixedly installed at the bottom end of the push rod 31 slides down in the slide groove 1 38 and extends to the inner cavity of the elastic core shaft 39. Since the push block 35 is a truncated cone with a top diameter larger than a bottom diameter, and in the initial state, the bottom end of the push block 35 extends to the inside of the elastic core shaft 39 and its surface is aligned with the elastic core shaft 39. The inner cavity surface abuts, and as the push block 35 moves downward, since the elastic core shaft 39 is composed of a plurality of arc-shaped spring pieces, the push block 35 will give the plurality of arc-shaped spring pieces an extrusion force to cause them to deform, and then the elastic core shaft 39 is stretched open. When stretched open, friction is generated between the surface of the elastic core shaft 39 and the inner cavity wall of the cavity 37. Under the action of the friction, the elastic core shaft 39 cannot slide in the cavity 37, and then the sleeve 34 is fixed in the slot 36, and a limiting component 33 is provided. During the sliding process of the push rod 31, the inclined surface of the right-angled triangle block 331 originally clamped in the upper side slot 334 is subjected to force.

[0043] The force decomposition shows that the right-angled triangle block 331 will be subjected to the force in the direction of the second slide groove 333. Under the action of the force, the right-angled triangle block 331 slides out of the slot 334 and slides into the second slide groove 333 while squeezing the spring 332. When the push block 35 is pushed until the surface of the expanded elastic core shaft 39 abuts against the inner surface of the cavity 37, the right-angled triangle block 331 just slides to the position corresponding to the lower side slot 334, and then rebounds and is connected to the slot 334 under the action of the spring 332. At the same time, the bottom of the handle 32 just abuts against the top of the valve cover 2. At this time, the push rod 31 cannot slide down or up, and the push rod 31 is limited at this position, and the push block 35 is also limited at this position to prevent the push block 35 from sliding in the slide groove 1 38, so that the force applied to the elastic core shaft 39 The force on the shaft 39 is reduced, causing it to rebound, so that the surface of the elastic core shaft 39 does not contact the inner surface of the cavity 37 and there is no friction, thereby preventing the elastic core shaft 39 and the sleeve 34 from sliding in the cavity 37 and the slot 36, so that the valve cover 2 is firmly fixed on the top of the valve body 1. When the valve cover 2 needs to be removed from the top of the valve body 1, the L-shaped lever 335 is pushed, and the L-shaped lever 335 slides in the slide groove three 336, thereby driving the right-angled triangle block 331 fixed thereto to slide out of the slot 334 and slide into the slide groove two 333, and then the push rod 31 is slid upward by the handle 32. When the push rod 31 drives the push block 35 to slide to the top of the slide groove one 38, the push rod 31 just slides to the position of the right-angled triangle block 331 corresponding to the upper slot 334.

[0044] At this time, release the hand that is pushing the L-shaped lever 335, and the right-angled triangle block 331 rebounds into the slot 334 under the action of the spring 332. At the same time, the force on the inner surface of the elastic core shaft 39 under the action of the push block 35 disappears, and the elastic core shaft 39 rebounds to its original position. The surface of the elastic core shaft 39 no longer abuts against the inner surface of the cavity 37 and there is no friction between them, so that the elastic core shaft 39 and the sleeve 34 can be pulled out from the cavity 37 and the slot 36, and then the valve cover 2 can be removed from the top of the valve body 1.

[0045] A sealing ring is provided between the upper end surface of the valve body 1 and the lower end surface of the valve cover 2 for sealing.

[0046] The implementation principle of a valve installation structure of the embodiment of the present application is as follows: the ball valve and other valves in the heat pump system can be installed by using the fixing component 3. During installation, the elastic core shaft 39 and the plug sleeve 34 are just completely inserted into the cavity 37 and the slot 36. Then, the push rod 31 is pushed by the handle 32, and the push rod 31 slides down in the slide groove 4 310 and the slide groove 5 311, and then the push block 35 fixedly installed at the bottom end of the push rod 31 slides down in the slide groove 1 38 and extends to the inner cavity of the elastic core shaft 39. The push block 35 will give a plurality of arc-shaped spring sheets a squeezing force to cause them to deform, and then the elastic core shaft 39 is stretched open. When stretched open, friction is generated between the surface of the elastic core shaft 39 and the inner wall of the cavity 37. Under the action of the friction, the elastic core shaft 39 cannot slide in the cavity 37, and then the plug sleeve 34 is fixed in the slot 36, and during the sliding process of the push rod 31;

[0047] The inclined surface of the right-angled triangle block 331 originally connected to the upper side slot 334 is stressed, and the right-angled triangle block 331 slides out of the slot 334 under the action of the force and slides into the second slide slot 333 while squeezing the spring 332. When the push block 35 is pushed until the surface of the expanded elastic core shaft 39 abuts against the inner surface of the cavity 37, the right-angled triangle block 331 just slides to the position corresponding to the lower side slot 334, and then rebounds and is connected to the slot 334 under the action of the spring 332, and the handle 32 The bottom just abuts against the top of the valve cover 2, and at this time, the push rod 31 cannot slide down or up, and then the push rod 31 is limited at this position, and the push block 35 is also limited at this position, preventing the push block 35 from sliding in the slide groove 1 38, and preventing the elastic core shaft 39 and the plug sleeve 34 from sliding in the cavity 37 and the slot 36, so that the valve cover 2 is firmly fixed on the top of the valve body 1. When the valve cover 2 needs to be removed from the top of the valve body 1, the L-shaped lever 335 is pushed, and the L-shaped lever 335 slides in the slide groove 336;

[0048] The push rod 31 then slides upwardly through the handle 32, and when the push rod 31 drives the push block 35 to slide to the top of the slide groove 1 38, the push rod 31 just slides to the position of the right-angled triangle block 331 corresponding to the upper side slot 334. At this time, the hand that pushes the L-shaped lever 335 is released, and the right-angled triangle block 331 rebounds into the slot 334 under the action of the spring 332. At the same time, the force on the inner cavity surface of the elastic core shaft 39 under the action of the push block 35 disappears, and the elastic core shaft 39 rebounds to its original position. The surface of the elastic core shaft 39 no longer abuts against the inner cavity surface of the cavity 37 and there is no friction between them. Therefore, the elastic core shaft 39 and the sleeve 34 can be pulled out from the cavity 37 and the slot 36, and the valve cover 2 is removed from the top of the valve body 1.

[0049] In summary, the setting of the fixing component 3 can enable the heat pump system, refrigerator and other equipment to quickly resume operation.

[0050] The above are only optional embodiments of the present disclosure and are not intended to limit the present disclosure. For those skilled in the art, the present disclosure may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure.
