Description

Technical Field

[0001] This application relates to the field of valves, and more particularly to a valve for regulating the flow of a water distributor. Background Technology

[0002] A manifold is a device used for fluid distribution and collection. Its core function is to evenly distribute the fluid in the main pipeline to multiple branch pipelines. It is widely used in heating, cooling and water treatment.

[0003] Because it is necessary to adjust the flow rate of each branch pipe, valves need to be installed at the manifold interface for flow regulation. However, manifold interfaces come in two types: internal thread and external thread. Users need to select a valve that is compatible with the manifold interface thread, which increases the installation difficulty between the manifold interface and the valve, thereby reducing the versatility of the valve. Summary of the Invention

[0004] To improve the versatility of valves, this application provides a valve for regulating the flow rate of a water distributor.

[0005] This application provides a flow regulating valve for a water distributor, which adopts the following technical solution:

[0006] A valve for regulating the flow of a water distributor includes a valve body. The surface of the valve body has a connecting flow channel through which fluid passes. The inner wall of the connecting flow channel has an internal thread groove for tightening the threads of the water distributor interface. The outer circumferential surface of the valve body away from the internal thread groove has an external thread groove for tightening the threads of the water distributor interface.

[0007] By adopting the above technical solution, an internal thread groove is opened on the inner wall of the connecting channel, and an external thread groove is opened on the outer circumferential surface of the valve body away from the internal thread groove. When installing the water distributor, the internal thread groove or external thread groove that matches the thread position of the water distributor interface is selected, which reduces the installation difficulty between the water distributor interface and the valve, thereby improving the versatility of the valve.

[0008] Optionally, the valve may also include a valve cover, a valve disc, a valve seat, and a valve stem. The valve cover is sealed to the surface of the valve body. The surface of the valve cover has a sliding cavity for the valve stem to slide. The sliding cavity is connected to a connecting flow channel. The valve disc is connected to the end of the valve stem located in the connecting flow channel. The valve seat is connected to the inner wall of the connecting flow channel facing the valve disc. The valve seat divides the connecting flow channel into two connecting sections. The surface of the valve seat facing the valve disc has an opening and closing cavity. The opening and closing cavity extends through both sides of the valve seat and connects the two connecting sections. When the valve stem slides along the inner wall of the sliding cavity toward the valve seat, the surface of the valve disc abuts against the inner wall of the opening and closing cavity and separates the two connecting sections.

[0009] By adopting the above technical solution, the valve stem is driven to slide along the inner wall of the sliding cavity, adjusting the distance between the valve disc and the valve seat, thereby achieving precise regulation of the fluid flow rate in the connecting flow channel. At the same time, the valve cover is fixed to the valve body surface by lead seal, making the valve less susceptible to damage from malicious disassembly, thus extending the service life of the valve and ensuring stable regulation of the fluid flow rate in the branch pipelines of the distributor.

[0010] Optionally, the valve body surface has an installation cavity for embedding a heat meter probe. The installation cavity is connected to one of the connecting sections, and the heat meter probe can be embedded in the installation cavity to detect the temperature and flow rate of the fluid in the connecting section.

[0011] By adopting the above technical solution, the heat meter probe is embedded in the installation cavity, and the end of the heat meter probe is located in the connection section to detect the temperature and flow rate of the fluid. The operator can adjust the distance between the valve disc and the valve seat according to the flow rate displayed by the heat meter to achieve precise adjustment of the flow rate of the branch pipeline.

[0012] Optionally, a plug is threaded onto the inner wall of the mounting cavity, and the plug seals the mounting cavity.

[0013] By adopting the above technical solution, when the valve is transported or stored, the plug is tightened and fixed to the inner wall of the installation cavity and the installation cavity is sealed, so that external impurities cannot easily enter the connection channel through the installation cavity, thus ensuring the cleanliness of the inner wall of the connection channel.

[0014] Optionally, the valve body is connected to a sealing assembly, which includes a sealing ring. The outer ring of the sealing ring is connected to the inner wall of the mounting cavity, and the inner ring of the sealing ring can press against the outer peripheral surface of the heat meter probe to form a seal.

[0015] By adopting the above technical solution, the outer ring of the sealing ring is connected to the inner wall of the mounting cavity, and the inner ring of the sealing ring can press against the outer peripheral surface of the heat meter probe to form a seal, so that the fluid in the connecting flow channel is not easy to overflow from the pressing point between the inner wall of the mounting cavity and the outer peripheral surface of the heat meter probe, thereby improving the sealing performance of the valve.

[0016] Optionally, the sealing assembly further includes multiple elastic blocks, which are spaced apart and connected to the inner wall of the mounting cavity. The multiple elastic blocks are spliced ​​together to form a circular plate and close the mounting cavity. When the end of the heat meter probe passes through the mounting cavity and is embedded in the connecting channel, the elastic block is deformed by the surface of the heat meter probe. The surface of the heat meter probe and the inner wall of the mounting cavity clamp the two sides of the elastic block to form a seal.

[0017] By adopting the above technical solution, multiple elastic blocks are spliced ​​together to form a circular plate and seal the installation cavity, making it difficult for external impurities to enter the connecting flow channel from the installation cavity, thereby further improving the sealing stability of the valve. When the end of the heat meter probe passes through the installation cavity and is embedded in the connecting flow channel, the elastic block is deformed by the pressure of the heat meter probe surface. The heat meter probe surface and the inner wall of the installation cavity clamp the two sides of the elastic block to form a seal, making it difficult for the fluid in the connecting flow channel to overflow from the tight joint between the inner wall of the installation cavity and the heat meter probe surface, thereby improving the stability of the valve in transporting fluid.

[0018] Optionally, the sealing assembly further includes a retaining ring bladder, and the inner wall of the mounting cavity is provided with a retaining cavity for the retaining ring bladder to be embedded. The retaining cavity is located on the side of the elastic block near the connecting section. When the elastic block is deformed by the pressure of the heat meter probe surface, the inner ring of the retaining ring bladder and the outer peripheral surface of the heat meter probe abut against both sides of the elastic block to form a seal.

[0019] By adopting the above technical solution, when the end of the heat meter probe passes through the mounting cavity and is embedded in the connecting flow channel, the elastic block is deformed by the pressure of the heat meter probe surface, and presses against the inner ring wall of the ring bladder and the outer peripheral surface of the heat meter probe against both sides of the elastic block to form a seal, thereby further improving the sealing stability of the valve.

[0020] Optionally, the sealing assembly further includes an inflation piston and an elastic element. The inner wall of the sealing cavity is provided with an inflation channel for the inflation piston to slide. One end of the inflation channel penetrates the outer wall of the valve body, and the other end of the inflation channel connects to the inner cavity of the sealing ring bladder. One end of the elastic element is connected to the bottom wall of the inflation channel in the elastic direction, and the other end of the elastic element is connected to the surface of the inflation piston. The elastic element has the elastic force to drive the inflation piston to slide away from the sealing ring bladder, and the end of the inflation piston tends to protrude from the surface of the valve body. When the end of the heat meter probe passes through the mounting cavity and is embedded in the connecting channel, the surface of the heat meter probe abuts against the surface of the inflation piston and pushes the inflation piston closer to the sealing cavity.

[0021] By adopting the above technical solution, when the end of the heat meter probe passes through the mounting cavity and is embedded in the connecting flow channel, the surface of the heat meter probe abuts against the surface of the inflation piston and pushes the inflation piston to slide along the inner wall of the inflation flow channel toward the direction of the pressing cavity. The inflation flow channel connects to the inner cavity of the pressing ring bladder, which drives the air in the inflation flow channel into the inner cavity of the pressing ring bladder. The inner cavity of the pressing ring bladder is pressurized and expanded and presses against the surface of the elastic block to form a seal, further improving the sealing stability between the surface of the elastic block and the inner wall of the pressing ring bladder.

[0022] Optionally, a positioning assembly is connected between the valve body and the inflation piston. The positioning assembly includes a positioning arc plate and a positioning block. A limiting cavity for the end of the heat meter probe is formed on the inner wall of the connecting section. The positioning arc plate is connected to the surface of the inflation piston facing the valve body. A positioning cavity for the positioning arc plate to be embedded is formed on the surface of the valve body. A slide for the positioning block to slide is formed on the inner wall of the positioning cavity. A positioning groove for the positioning block to be embedded is formed on the surface of the positioning arc plate. When the end of the heat meter probe passes through the mounting cavity and the connecting section and is embedded in the limiting cavity, the inner wall of the limiting cavity abuts against the outer peripheral surface of the heat meter probe to form a limit. The positioning arc plate is embedded in the positioning cavity. The positioning groove connects to the slide, pushing the positioning block to slide along the inner wall of the slide towards the positioning groove. The end of the positioning block is embedded in the positioning groove to form a limit.

[0023] By adopting the above technical solution, when the end of the heat meter probe passes through the mounting cavity and connecting section and is embedded in the limiting cavity, the inner wall of the limiting cavity abuts against the outer peripheral surface of the heat meter probe to form a limit; at the same time, the heat meter abuts against the inflation piston and pushes the inflation piston to slide along the inflation channel toward the direction closer to the pressing cavity, driving the positioning arc plate to approach the positioning cavity and embed. The positioning groove connects to the slide, pushing the positioning block to slide along the inner wall of the slide toward the direction closer to the positioning groove. The end of the positioning block is embedded in the positioning groove, and the surface of the positioning block abuts against the inner wall of the positioning groove to form a limit, making it difficult for the inflation piston to deviate in the inner wall of the inflation channel, thereby improving the limiting stability of the inflation piston in the inflation channel.

[0024] Optionally, the positioning component further includes an elastic element two, one end of which is connected to the surface of the positioning block in the elastic direction, and the other end of which is connected to the inner wall of the slide. The elastic element two has the elastic force to drive the positioning block to slide towards the positioning groove, and the end of the positioning block tends to be embedded in the positioning groove.

[0025] By adopting the above technical solution, when the positioning arc plate is embedded in the positioning cavity and the positioning groove is connected to the slide, the elastic force of the elastic element drives the positioning block to slide towards the positioning groove. The end of the positioning block is embedded in the positioning groove, and the outer wall of the positioning block abuts against the inner wall of the positioning groove to form a limit, making the positioning block less prone to displacement, thereby improving the positioning stability of the positioning arc plate in the positioning cavity.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. The setting of internal and external thread grooves: Select the appropriate internal or external thread groove according to the thread position of the manifold interface to reduce the installation difficulty between the manifold interface and the valve, thereby improving the versatility of the valve.

[0028] 2. The valve cover is fixed to the valve body surface with a lead seal. The valve cover is fixed to the valve body surface with a lead seal, which makes the valve less susceptible to damage from malicious disassembly, thereby extending the service life of the valve and ensuring stable regulation of fluid flow in the branch pipelines of the distributor.

[0029] 3. The installation cavity allows operators to adjust the distance between the valve disc and the valve seat based on the flow rate displayed by the heat meter, thereby achieving precise adjustment of the flow rate in the branch pipeline. Attached Figure Description

[0035] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0036] This application discloses a valve for regulating the flow rate of a water distributor. (Refer to...) Figure 1 and Figure 2The flow regulating valve for the distributor includes a valve body 1, a valve cover 2, a valve disc 3, a valve seat 4, a valve stem 5, and a handwheel 6. The surface of the valve body 1 has a connecting flow channel 11 for fluid flow, which runs through both sides of the valve body 1. One end of the connecting flow channel 11 has an internal thread groove 12 for tightening the distributor interface thread on its inner wall. The outer circumferential surface of the valve body 1 away from the internal thread groove 12 has an external thread groove 13 for tightening the distributor interface thread. The internal thread groove 12 and the external thread groove 13 are located at both ends of the connecting flow channel 11 along its length. When installing the distributor and the valve, the operator can select the appropriate internal thread groove 12 or external thread groove 13 according to the thread position of the distributor interface, reducing the installation difficulty between the distributor interface and the valve, thereby improving the versatility of the valve.

[0037] Reference Figure 1 and Figure 2 The valve cover 2 is fixed to the surface of the valve body 1 by a lead seal. A sliding cavity 21 for the valve stem 5 to slide is opened on the surface of the valve cover 2. The sliding cavity 21 passes through both sides of the valve cover 2 and connects to the connecting flow channel 11. The axis of the valve stem 5 and the length direction of the connecting flow channel 11 are perpendicular to each other. The end of the valve stem 5 facing the connecting flow channel 11 is connected to the end face of the valve disc 3. The end of the valve stem 5 protruding from the valve cover 2 is connected to the end face of the handwheel 6. The handwheel 6 and the valve disc 3 are located at both ends in the axial direction of the valve stem 5. The valve seat 4 is integrally formed and fixed to the inner wall of the connecting flow channel 11 facing the valve disc 3. The valve seat 4 divides the connecting flow channel 11 into two connecting sections 111. An opening and closing cavity 41 is opened on the surface of the valve seat 4 facing the valve disc 3. The opening and closing cavity 41 passes through both sides of the valve seat 4 and connects the two connecting sections 111.

[0038] Reference Figure 1 and Figure 2 When the valve needs to be closed, the handwheel 6 provides a point of force, and the handwheel 6 drives the valve stem 5 to slide along the inner wall of the sliding cavity 21 towards the valve seat 4, which in turn drives the valve disc 3 to approach the opening and closing cavity 41. The end face of the valve disc 3 presses against the inner wall of the opening and closing cavity 41 and separates the two connecting sections 111. When the valve needs to be opened, the handwheel 6 drives the valve stem 5 to slide along the inner wall of the sliding cavity 21 away from the valve seat 4, which in turn drives the valve disc 3 away from the opening and closing cavity 41. The pressing effect between the end face of the valve disc 3 and the inner wall of the opening and closing cavity 41 disappears. By adjusting the distance between the valve disc 3 and the valve seat 4, the flow rate of the fluid in the connecting flow channel 11 can be precisely adjusted.

[0039] Reference Figure 1 and Figure 2The valve body 1 has a mounting cavity 14 on its surface into which a heat meter probe is embedded. The mounting cavity 14 is connected to a connecting section 111 near the external thread groove 13. The heat meter probe can pass through the mounting cavity 14 and be embedded in the connecting section 111. The heat meter probe can detect the fluid temperature and flow rate in the connecting section 111 in real time, allowing the operator to accurately control the flow rate of the fluid passing through the valve and directly observe the temperature changes in the connecting section 111. A limiting cavity 15 is provided on the inner wall of the connecting section 111 facing the mounting cavity 14, into which the end of the heat meter probe is embedded. The inner wall of the limiting cavity 15 abuts against the surface of the heat meter probe to form a limit, making the heat meter probe less likely to swing due to fluid impact in the connecting section 111, thereby improving the limiting stability of the heat meter probe in the mounting cavity 14.

[0040] Reference Figure 1 and Figure 2 A plug 7 is threadedly connected to the inner wall of the mounting cavity 14. The plug 7 seals the mounting cavity 14, making it difficult for external impurities to enter the connecting flow channel 11 from the mounting cavity 14 during valve transportation and storage, thereby ensuring the stability of valve storage.

[0041] Reference Figure 2 and Figure 3 The valve body 1 is equipped with a sealing assembly 8, which can improve the sealing performance between the heat meter probe and the inner wall of the mounting cavity 14. The sealing assembly 8 includes a sealing ring 81, a clamping ring 82, an inflatable piston 83, an elastic element 84, and multiple elastic blocks 85. The sealing ring 81 can be made of rubber or silicone. In this embodiment, the sealing ring 81 is made of rubber and has a certain deformation capability. The inner wall of the mounting cavity 14 is provided with a sealing groove 16 for the sealing ring 81 to be embedded. The outer ring of the sealing ring 81 abuts against the inner wall of the sealing groove 16 to form a seal, and the inner ring of the sealing ring 81 abuts against the outer peripheral surface of the heat meter probe to form a seal, so that the fluid in the connecting section 111 is not easy to overflow from the abutment between the inner wall of the mounting cavity 14 and the outer peripheral surface of the heat meter probe, thus achieving a preliminary seal between the outer peripheral surface of the heat meter probe and the inner wall of the mounting cavity 14.

[0042] Reference Figure 2 and Figure 3 The elastic block 85 can be made of rubber or silicone. In this embodiment, the elastic block 85 is made of rubber and has a certain deformation capability. Multiple elastic blocks 85 are spaced apart and connected to the inner wall of the mounting cavity 14 near the connecting section 111. Multiple elastic blocks 85 are spliced ​​together to form a circular plate and close the mounting cavity 14. The elastic blocks 85 and the sealing ring 81 are located at both ends of the mounting cavity 14 along its length. When the end of the heat meter probe passes through the mounting cavity 14 and the connecting section 111 and is embedded in the limiting cavity 15, the elastic block 85 is deformed by the heat meter probe. The outer peripheral surface of the heat meter probe and the inner wall of the mounting cavity 14 press against both sides of the elastic block 85 to form a seal, thereby achieving a secondary seal between the outer peripheral surface of the heat meter probe and the inner wall of the mounting cavity 14, and further improving the sealing stability of the valve.

[0043] Reference Figure 2 and Figure 3 The material of the clamping ring 82 can be rubber or silicone. In this embodiment, the material of the clamping ring 82 is rubber, which has a certain deformation capability. The inner wall of the mounting cavity 14 is provided with a clamping cavity 17 for the clamping ring 82 to be embedded. The clamping cavity 17 is located on the side of the elastic block 85 near the connecting section 111. When the elastic block 85 is deformed by the heat meter probe, the inner ring of the clamping ring 82 and the outer peripheral surface of the heat meter probe clamp the two sides of the elastic block 85 to form a seal, which further improves the sealing stability of the valve.

[0044] Reference Figure 2 and Figure 3 The inflation piston 83 can be made of rubber or silicone. In this embodiment, the inflation piston 83 is made of rubber and has a certain deformation capability. An inflation channel 18 is provided on the inner wall of the pressing cavity 17 for the inflation piston 83 to slide. The sliding direction of the inflation piston 83 is parallel to the insertion direction of the heat meter probe, and the inflation channel 18 is connected to the inner cavity of the pressing ring bladder 82. The elastic element 84 can be a compression spring or a tension spring. In this embodiment, the elastic element 84 is a compression spring and has a certain deformation capability. One end of the elastic element 84 in the elastic direction is connected to the surface of the inflation piston 83, and the other end of the elastic element 84 in the elastic direction is connected to the inner wall of the inflation channel 18. The elastic element 84 has the elastic force to drive the inflation piston 83 to slide away from the pressing ring bladder 82, and the end of the inflation piston 83 tends to protrude from the surface of the valve body 1.

[0045] Reference Figure 2 and Figure 3 When the end of the heat meter probe passes through the mounting cavity 14 and the connecting section 111 and is embedded in the limiting cavity 15, the elastic block 85 is deformed by the heat meter probe, pressing against the inner ring of the sealing ring 82 and the outer peripheral surface of the heat meter probe against both sides of the elastic block 85 to form a seal; at the same time, the surface of the heat meter probe abuts against the end face of the inflation piston 83 and drives the inflation piston 83 to slide towards the sealing cavity 17. The inflation passage 18 connects to the inner cavity of the sealing ring 82. The air in the inflation passage 18 enters the inner cavity of the sealing ring 82, the inner cavity of the sealing ring 82 is pressurized and expands and presses against the surface of the elastic block 85, further increasing the pressing force between the inner ring wall of the sealing ring 82 and the outer peripheral surface of the heat meter probe against both sides of the elastic block 85, thereby improving the sealing stability of the valve.

[0046] Reference Figure 2 and Figure 4A positioning assembly 9 is connected between the valve body 1 and the inflation piston 83. The positioning assembly 9 can directionally limit the inflation piston 83 within the inflation passage 18. The positioning assembly 9 includes a positioning arc plate 91, a positioning block 92, and an elastic element 93. The positioning arc plate 91 is connected to the surface of the inflation piston 83 facing the valve body 1. A positioning cavity 19 is provided on the surface of the valve body 1 for the positioning arc plate 91 to be embedded. A slide rail 110 is provided on the inner wall of the positioning cavity 19 for the positioning block 92 to slide. A positioning groove 911 is provided on the surface of the positioning arc plate 91 for the end of the positioning block 92 to be embedded.

[0047] Reference Figure 2 and Figure 4 The second elastic element 93 can be a compression spring or a tension spring. In this embodiment, the second elastic element 93 is a compression spring, which has a certain deformation capability. One end of the second elastic element 93 in the elastic force direction is connected to the surface of the positioning block 92, and the other end of the second elastic element 93 in the elastic force direction is connected to the inner wall of the slide 110. The second elastic element 93 has the elastic force to drive the positioning block 92 to slide towards the positioning groove 911, and the end of the positioning block 92 tends to be embedded in the positioning groove 911.

[0048] Reference Figure 2 and Figure 4 When the end of the heat meter probe passes through the mounting cavity 14 and the connecting section 111 and is embedded in the limiting cavity 15, the surface of the heat meter abuts against the surface of the inflation piston 83 and pushes the inflation channel 18 to slide towards the direction of the pressing cavity 17, causing the positioning arc plate 91 to slide towards the direction of the positioning cavity 19. The positioning arc plate 91 is embedded in the positioning cavity 19, and the positioning groove 911 is connected to the slide rail 110. The elastic element 2 93 drives the positioning block 92 to slide towards the direction of the positioning groove 911. The end of the positioning block 92 is embedded in the positioning groove 911, and the outer wall of the positioning block 92 abuts against the inner wall of the positioning groove 911 to form a limit, so that the inflation piston 83 is not easy to deviate from the inner wall of the inflation channel 18, thereby improving the sealing stability of the inner ring wall of the pressing ring 82 and the outer peripheral surface of the heat meter probe against both sides of the elastic block 85.

[0049] The implementation principle of a flow regulating valve for a water distributor according to an embodiment of this application is as follows: During the installation of the water distributor, the internal thread groove 12 or the external thread groove 13 that matches the thread position of the water distributor interface is selected to reduce the installation difficulty between the water distributor interface and the valve, thereby improving the versatility of the valve; when the user needs to monitor the flow rate and temperature of the fluid flowing through the valve in real time, the plug 7 is unscrewed, so that the sealing effect of the plug 7 on the installation cavity 14 is eliminated, and the end of the heat meter probe passes through the installation cavity 14 and the connecting section 111 and is embedded in the limiting cavity 15. The elastic block 85 is deformed by the pressure of the heat meter probe, and the inner ring of the tight ring 82 and the outer peripheral surface of the heat meter probe are pressed against the two sides of the elastic block 85 to form a seal; at the same time, the surface of the heat meter probe abuts against the end face of the inflation piston 83 and drives the inflation piston 83 to slide towards the tight cavity 17, and the inflation air passage 18 connects to the inner cavity of the tight ring 82. Air from the inflation channel 18 enters the inner cavity of the sealing ring bladder 82, pressurizing and expanding the inner cavity of the sealing ring bladder 82 and pressing against the surface of the elastic block 85. This further increases the pressing force between the inner wall of the sealing ring bladder 82 and the outer peripheral surface of the heat meter probe against both sides of the elastic block 85, thereby improving the sealing stability of the valve. At the same time, it drives the positioning arc plate 91 to slide towards the positioning cavity 19. The positioning arc plate 91 is embedded in the positioning cavity 19, and the positioning groove 911 is connected to the slide rail 110. The elastic element 93 drives the positioning block 92 to slide towards the positioning groove 911. The end of the positioning block 92 is embedded in the positioning groove 911, and the outer wall of the positioning block 92 presses against the inner wall of the positioning groove 911 to form a limit, making it difficult for the inflation piston 83 to deviate from the inner wall of the inflation channel 18, thereby improving the sealing stability between the inner wall of the sealing ring bladder 82 and the outer peripheral surface of the heat meter probe against both sides of the elastic block 85.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
