Description

Technical Field

[0001] This utility model belongs to the field of pressure regulating valve technology, and relates to a new push-type pressure regulating valve. Background Technology

[0002] A pressure regulating valve is an intuitive and simple flow regulation and control device. In pipeline networks, the flow rate can be directly set according to the design. The valve can automatically eliminate the flow deviation caused by the residual pressure head and pressure fluctuations in the pipeline under the action of water. Currently, push-type pressure regulating valves are more widely used.

[0003] During the use of traditional push-type pressure regulating valves, we found that the push rod pin of the push-type pressure regulating valve is a fixed design, usually with an interference fit, which makes disassembly difficult. When the internal return needle valve of the push-type pressure regulating valve is damaged, the parts are not easy to replace, and the entire component needs to be replaced, resulting in high replacement costs. Therefore, we designed a new push-type pressure regulating valve to solve the above technical problems. Utility Model Content

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] like Figure 1-5 As shown, the novel push-type pressure regulating valve of this utility model includes a valve body 1. A return water pipe 4 is detachably and fixedly installed on the top of the valve body 1 through an upper mounting plate 3 and a screw 16. A push handle 5 is sleeved and connected to the surface of the return water pipe 4. An adjustment spring 10 is nested inside the return water pipe 4. A lower plug 11 is fixedly connected to the lower end of the spring 10. A detachable push rod pin 6 is inserted and connected to the center of the lower plug 11. Both sides of the bottom of the return water pipe 4 are provided with strip-shaped through holes 8 for adjusting the rise and fall of the push rod pin 6. The two ends of the push rod pin 6 pass through the strip-shaped through holes 8 and are detachably and fixedly connected to the push handle 5.

[0020] Specifically, the rotation of the push handle 5 can drive the push rod pin 6 to rise and fall. The rise and fall of the push rod pin 6 can drive the rise and fall of the return needle 12 and the return needle valve 13. At the same time, the push rod pin 6 is detachable, replacing the traditional fixed design, which facilitates the disassembly of the push rod 6, spring 10 and lower plug 11 of the pressure regulating valve, thereby facilitating the replacement of some internal parts of the pressure regulating valve.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the new push-type pressure regulating valve of this utility model includes a push handle 501 and a collar 502. The collar 502 is nested and connected to the outer surface of the return water pipe 4. A handle 501 for pushing the collar 502 to rotate is fixedly installed on one side of the outer surface of the collar 502.

[0022] Both sides of the inner wall of the collar 502 are provided with symmetrically arranged inclined grooves 503. The top and bottom of the inclined groove 503 are provided with positioning grooves 504 that are adapted to the size of the push rod pin 6. Both ends of the push rod pin 6 extend into the interior of the inclined groove 503 and the ends of the push rod pin 6 fit into the positioning grooves 504.

[0023] Specifically, the rotation of the handle 501 drives the rotation of the collar 502, and the inclined groove 503 on the inner wall of the collar 502 causes the push rod pin 6 to rise and fall, which in turn drives the rise and fall of the return needle valve 13.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the new push-type pressure regulating valve of this utility model has a threaded rod 9 threadedly connected to the top of the return water pipe 4, an upper plug 14 sleeved and connected to the top of the inside of the return water pipe 4, the bottom end of the upper plug 14 being fixedly connected to the top of the spring 10, the bottom end of the threaded rod 9 extending into the inside of the return water pipe 4 and abutting against the top of the upper plug 14, a pressure regulating wheel 7 being fixedly installed at the top of the threaded rod 9, and a pressure regulating fixing plate 15 being fixedly installed at the connection between the threaded rod 9 and the pressure regulating wheel 7.

[0025] Specifically, the pressure adjusting wheel 7 drives the rotation of the threaded rod 9, which in turn compresses the spring 10.

[0026] A return needle 12 is detachably and fixedly installed at the bottom end of the lower plug 11, and a return needle valve 13 is fixedly installed inside the valve body 1 extending from the return needle 12.

[0027] Specifically, the return needle valve 13 and the lower plug 11 are connected as one unit through the return needle 12.

[0028] An overflow outlet 2 for connection is fixed on one side of the valve body 1, and an inlet is opened at the bottom of the valve body 1, which is connected to the outlet of the machine.

[0029] In specific implementation, during use, the pressure regulating valve pushes the push rod 16, return needle 12, and return needle valve 13 upwards under the action of the machine's water pressure. At the same time, during the upward movement of the push rod 16, return needle 12, and return needle valve 13, the spring 10 pushes the lower plug 11 downwards, thereby pushing the push rod 16, return needle 12, and return needle valve 13 back to their original positions, thus realizing the pressure relief function of the machine's water pressure.

[0030] When it is necessary to disassemble some parts of the pressure regulating valve for repair, first loosen the pressure regulating wheel 7 by turning it clockwise, then remove the two screws of the pressure regulating fixing plate 15, the operator lifts the lower plug 11, then pulls out the push rod pin 6, and then disassembles the entire pressure regulating valve for repair, which is very convenient.
