Description

Technical Field

[0001] The invention relates to an intelligent water pressure regulating guide valve, belonging to the technical field of water pressure control valves. Background Art

[0002] At present, in order to respond to the water pressure changes in the supply pipeline, the water supply network will use a pressure-control valve body. The pressure-control valve body is generally used together with the main valve. When the pressure of the pressure-control valve body changes, the pressure in the main valve will change accordingly, causing the main valve diaphragm to shift, thereby controlling the outlet size, improving the sensitivity of the valve core control, and achieving the effect of precise pressure stabilization.

[0003] Traditionally, the control valve body Figure 3 As shown, it uses a spiral adjustment screw designed at the top. The screw uses a spring to adjust the diaphragm's upward and downward movement, thereby increasing or decreasing pressure. Existing control valve bodies are relatively stable and offer good pressure control when used in conjunction with a hydraulic control valve. However, manual pressure adjustment is required, which is inefficient and poses risks. The pressure is relatively fixed and requires manual adjustment. Changing the pressure requires on-site pressure adjustment. In some special environments, such as multiple pressure adjustments to find the most stable pressure control effect and in harsh environments, pressure adjustment can be difficult. Furthermore, the pilot valve cannot be automatically closed, making it difficult to close the valve in emergency situations. Summary of the Invention

[0023] The present application provides a smart water pressure regulating guide valve. The technical solutions of the present application are described in detail below with reference to the drawings, so as to make it easier to understand and master.

[0024] The smart water pressure regulating guide valve is connected with a water supply main valve, as shown in Figure 1 and Figure 2 , and includes a guide valve body 1.

[0025] Generally, the water supply main valve includes a water inlet pipe end and a water outlet pipe end, and the guide valve body 1 is consistent with the existing control valve body, which is arranged between the water inlet pipe end and the water outlet pipe end of the water supply main valve, and meets the stable pressure regulating requirement between the water inlet pipe end and the water outlet pipe end.

[0026] In the present application, the guide valve body 1 includes a pressure regulating mechanism 4 and a bottom chamber 2 and a top chamber 3 which are separated.

[0027] The bottom chamber 2 includes a water inlet high-pressure end 21, a water outlet low-pressure end 22, and a communication pipeline 23 between the water inlet high-pressure end 21 and the water outlet low-pressure end 22. In the stable flow process, the flow regulating effect is achieved by regulating the flow of the communication pipeline 23.

[0028] The top chamber 3 includes an inlet and outlet pipeline 31, an adjusting drive end 32 with lifting displacement in the top chamber 3, and a remote control end 33 for remotely controlling the lifting displacement of the adjusting drive end 32. The inlet and outlet pipeline 31 can be connected to an independent pressure regulating water bag, a water inlet pipe end or a water outlet pipe end of the water supply main valve, and a pressure regulating valve can be arranged on the inlet and outlet pipeline 31. The adjusting drive end 32 has a drive source, which can be a motor, a cylinder or the like, and the drive source is connected to the remote control end 33 through a remote communication module. The drive source can be controlled through the remote control end 33, so as to realize the lifting displacement adjustment of the adjusting drive end 32.

[0029] The pressure regulating mechanism 4 includes a first isolation membrane 41 at the top of the bottom chamber, a second isolation membrane 42 at the bottom of the top chamber, and an elastic guide valve 5 in the bottom chamber for regulating the flow of the communication pipeline 23.

[0030] A communication elastic body 43 is arranged between the membrane seat of the first isolation membrane 41 and the membrane seat of the second isolation membrane 42, the membrane seat of the first isolation membrane 41 is connected to the elastic guide valve 5, and the membrane seat of the second isolation membrane 42 has a driven end 421 arranged opposite to the adjusting drive end 32.

[0031] Specifically, a voltmeter is installed at the low-pressure outlet port 22 of the bottom chamber 2. In this case, the voltmeter is a remote meter. The remote control terminal 33 monitors the pressure data from the remote meter, thereby controlling the vertical displacement of the regulating drive terminal 32 and ultimately adjusting the required water pressure. The remote control terminal 33 can also be set to a threshold. When the pressure on the remote meter exceeds the threshold, automatic pressure regulation is achieved.

[0032] First, the pressure increase adjustment of the low-pressure end 22 of the water outlet is explained. During pressure increase, the remote control end 33 drives the adjustment driving end 32 to press downward, causing the second isolation diaphragm 42 to move downward and compressing the connecting elastic body 43 to produce elastic deformation. At this time, the top chamber 3 is expanded as a whole, and the inlet and outlet water pipes 31 cause high-pressure water to assist in compressing the second isolation diaphragm 42, and jointly drive the first isolation diaphragm 41 downward. The membrane seat of the first isolation diaphragm 41 drives the elastic guide valve 5, causing the elastic guide valve 5 to move downward, and the flow of the connecting pipe 23 is increased, thereby pressurizing the low-pressure end 22 of the water outlet.

[0033] The water outlet low-pressure end 22 is described as undergoing pressure reduction regulation. During pressure reduction, the remote control end 33 drives the regulating drive end 32 upward. At this time, the elastic guide valve 5 is elastically released to produce a deformation reset drive on the first isolation diaphragm 41, and the connecting elastic body 43 also produces an elastic reset operation to produce a reset drive on the second isolation diaphragm 42. When the second isolation diaphragm 42 is reset, it will compress the top chamber 3 to contract, thereby drawing out the water in the top chamber 3 and reducing the pressure in the top chamber 3. The pressure is maintained when the membrane seat of the second isolation diaphragm 42 abuts against the regulating drive end 32.

[0034] When the outlet low-pressure end 22 is closed, the regulating drive end 32 rises to the top, and the second isolation diaphragm 42 is reset and has no contact with the regulating drive end 32. At this time, the elastic guide valve 5 closes the connecting pipe 23, thereby closing the regulating guide valve.

[0035] In a specific embodiment, in order to reduce the regulating pressure of the regulating drive end 32, a regulating chamber 6 located between the bottom chamber 2 and the top chamber 3 is provided in the guide valve body 1, the connecting elastomer 43 is located in the regulating chamber 6, and the regulating chamber 6 is connected to the external atmosphere.

[0036] Specifically, when the pressure is increased, atmospheric pressure is used to eliminate a portion of the pressure in the bottom chamber 2 of the first isolation diaphragm 41 , thereby easing the downward driving pressure of the regulating driving end 32 and reducing driving energy consumption.

[0037] In a specific embodiment, the water inlet high-pressure end 31 includes an L-shaped water inlet elbow 7 extending into the bottom chamber 2, and the elastic guide valve 5 is arranged at the bottom of the L-shaped water inlet elbow, and the elastic guide valve 5 is arranged vertically opposite to the water outlet end of the L-shaped water inlet elbow 7.

[0038] That is, in the adjustment process, the outflow end of the L-shaped water inlet bend 7 is adjusted by the lifting of the elastic guide valve 5, so as to control the flow, and the pressure regulation function is realized.

[0039] More specifically, the elastic guide valve 5 includes a guide valve body 51 and an elastic seat 52 sealed in the bottom chamber, and the membrane seat of the first isolation membrane 41 is provided with a door-shaped connecting piece 53 for avoiding the L-shaped water inlet bend 7.

[0040] The design is more ingenious, and more preferably, the guide valve body 51 has a flexible end towards the outflow end of the L-shaped water inlet bend 7, which can block the outflow end.

[0041] In one embodiment, the guide valve body 1 includes an upper cover 11, a valve body 12, and a base 13, and the first isolation membrane 41 is sealed between the valve body and the base, and the second isolation membrane 42 is sealed between the upper cover and the valve body.

[0042] The design facilitates the assembly of the guide valve body 1, and the double-layer isolation membrane has a better sealing effect, and the sealing isolation between the chambers is reliable and stable.

[0043] From the above description, it can be found that the intelligent water pressure control guide valve has an automatic pressure regulating mechanism, and the design of the top chamber meets the driving requirements of pressure regulation, and the pressure regulation and automatic adjustment can be performed through the remote end, realizing remote connection, reducing the difficulty and risk of on-site adjustment. The three-chamber cooperation mode can utilize water pressure and air pressure for regulation and control, reducing the driving pressure of active adjustment and reducing the driving energy consumption. The overall design is simple and ingenious, the regulation and control are convenient, the response is efficient, and the production and assembly are easy, and it is suitable for popularization and application.

[0044] The technical solutions of the present application are fully described above, and it should be noted that the specific embodiments of the present application are not limited by the above description, and all technical solutions formed by equivalent transformation or equivalent transformation in structure, method or function according to the spirit and essence of the present application fall within the protection scope of the present application.
