Abstract
Description
Technical Field
[0001] The present application relates to the technical field of regulating valves, and specifically relates to a high-low pressure bypass regulating valve with strong leak prevention performance. Background Art
[0002] A bypass regulating valve is a valve used to control the fluid flow rate, usually used in a pipeline system. Its basic principle is to control the flow rate by adjusting the path of the fluid flowing through the valve, rather than directly adjusting the flow rate of the fluid through the main pipeline. The bypass regulating valve can adjust the opening and closing degree of the bypass, thereby changing the diversion ratio of the fluid between the main pipeline and the bypass. By increasing or decreasing the opening of the bypass, the actual flow rate of the fluid through the main pipeline can be adjusted;
[0003] In the existing bypass regulating valve, the connection between the valve and the pipeline is sealed by docking two flange plates and a sealing gasket, and water leakage may occur at the pipeline connection. Summary of the Invention
[0004] The purpose of the present application is to provide a high-low pressure bypass regulating valve with strong leak prevention performance for the deficiencies of the existing technology. Through the settings of the first flange plate, fixed pipe, elastic sleeve ring, second flange plate and sleeve, the connecting ring is stuck between the elastic ring and the plugging ring, and the connecting ring, elastic ring and plugging ring seal the connection between the fixed ring and the fixed pipe, so as to achieve the purpose of preventing leakage at the connection between the regulating valve and the pipeline.
[0005] The technical solution of the present application is as follows: A high-low pressure bypass regulating valve with strong leak prevention performance, including a valve body, a valve cover is arranged above the valve body, a valve stem is arranged in the valve body and the valve cover, fixed components are respectively arranged on both sides of the valve body, a connecting component is arranged on one side of the fixed component, the fixed component includes a first flange plate fixedly connected to both sides of the valve body, a fixed pipe is fixedly connected to one side of the first flange plate, an elastic sleeve ring is sleeved on the outer side of the fixed pipe close to the first flange plate, and the connecting component is sleeved on the outer side of the fixed pipe.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] To enable those skilled in the art to better understand the technical solutions in this application, the following will clearly and completely describe the technical solutions in the embodiments of this application in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.
[0021] As Figure 1 and Figure 2 shown, a high-low pressure bypass regulating valve with strong leak-proof performance includes a valve body 1, a valve cover 2 is arranged above the valve body 1, a valve rod 3 is arranged inside the valve body 1 and the valve cover 2, fixing components 5 are respectively arranged on both sides of the valve body 1, and a connecting component 6 is arranged on one side of the fixing component 5. The fixing component 5 includes first flange plates 51 fixedly connected to both sides of the valve body 1. A plurality of round holes are formed in the first flange plates 51. A fixing pipe 52 is fixedly connected to one side of the first flange plates 51. An elastic collar 53 is sleeved on the outside of the fixing pipe 52 close to the first flange plates 51. The connecting component 6 is sleeved on the outside of the fixing pipe 52, and the elastic collar 53 is extruded so that the connecting component 6 and the fixing pipe 52 are directly sealed.
[0022] In this embodiment, when using the regulating valve, the connecting component 6 is sleeved on the fixing pipe 52, the fixing pipe 52 completely enters the connecting component 6, the connecting component 6 extrudes the elastic collar 53, and the elastic collar 53 deforms to completely fill the gap between the connecting component 6 and the fixing pipe 52, fixing the connecting component 6 and the first flange plate 51 together. When water flows through the fixing pipe 52 and the connecting component 6, the water flow is blocked by the elastic collar 53 and cannot leak out from the gap between the fixing pipe 52 and the connecting component 6.
[0023] As Figures 3 - 5 shown, a fixing ring 521 is fixedly connected to the outside of the fixing pipe 52. A slot 522 is formed inside the fixing ring 521. A sealing gasket 523 is fixedly connected to one side of the inner wall of the slot 522. A connecting ring 524 is fixedly connected to one side inside the fixing ring 521, and the cross-section of the connecting ring 524 is a right triangle.
[0024] The connecting component 6 includes a second flange plate 61. A plurality of round holes are formed in the second flange plate 61. The first flange plate 51 and the second flange plate 61 are connected together by bolts. A sleeve 62 is fixedly connected to one side of the second flange plate 61. A cavity 621 is formed inside the sleeve 62. A blocking ring 622 is fixedly connected to one side inside the cavity 621. The blocking ring 622 is made of rubber and is matched with the connecting ring 524. A docking pipe 623 is fixedly connected inside the sleeve 62. A groove 624 is formed on the outside of the docking pipe 623, and an elastic ring 625 is fixedly arranged in the groove 624. The elastic ring 625 is made of rubber.
[0025] Above the valve cover 2, there is a diaphragm actuator 4. The diaphragm actuator 4 is connected to the valve stem 3. The diaphragm actuator 4 is used to drive the valve stem 3 to move within the valve body 1 to control the water flow rate.
[0026] In this embodiment, when using the regulating valve, the sleeve 62 is sleeved outside the fixing ring 521. The fixing ring 521 is inserted into the cavity 621. The connecting ring 524 first presses the elastic ring 625. When the fixing ring 521 is completely inserted into the cavity 621, the elastic ring 625 is located behind the connecting ring 524. After being stuck to the connecting ring 524, the gap between the connecting ring 524 and the docking pipe 623 is blocked. When the fixing ring 521 is completely inserted into the cavity 621, the sealing ring 622 fits together with the connecting ring 524. The sealing ring 622 blocks the other side of the connecting ring 524. The docking pipe 623 is inserted into the slot 522. The docking pipe 623 presses against the gasket 523. After the bolt connects the fixing component 5 and the connecting component 6 through the round holes on the first flange 51 and the second flange 61, the water flowing through the fixing pipe 52 and the sleeve 62 will be completely blocked by the cooperation of the elastic sleeve ring 53, the gasket 523, the connecting ring 524, the elastic ring 625 and the sealing ring 622 and will not leak out, preventing water from leaking out from the water pipe connection when using the regulating valve.
