Detailed Implementation

[0020] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0021] First Embodiment

[0022] Please see Figures 1-2 , Figure 1 This is a cross-sectional view of a high-pressure resistant valve device and control system according to the first embodiment of the present invention; Figure 2 This is a partial enlarged view of detail A of a high-pressure resistant valve device and control system according to the first embodiment of the present invention.

[0023] This invention provides a high-pressure resistant valve device, comprising a housing 101, a rotating disk 102, a valve plate 103, and a pressure-resistant component 104. The pressure-resistant component 104 includes a valve chamber 105, an inlet pipe 106, a drain pipe 107, a support member 108, a rubber pad 116, and a sealing ring 117. The support member 108 includes a support plate 111, a screw 112, a support disk 113, a first telescopic pipe 114, and a second telescopic pipe 115. The valve chamber 105 has a semi-circular groove 109 and a square groove 110. The support plate 111 has a through hole 118. This solution addresses the problem that existing devices rely solely on ultra-high hardness materials to improve high-pressure resistance, which primarily depends on the material's inherent hardness, resulting in limited effectiveness in enhancing high-pressure resistance due to the device's structure. This solution improves high-pressure resistance while reducing the requirements for raw material quality.

[0024] In this embodiment, the rotating disk 102 is rotatably connected to the outer casing 101 and is located on one side of the outer casing 101; the valve plate 103 is fixedly connected to the rotating disk 102 and rotatably connected to the outer casing 101; the rotating disk 102 is used to control the rotation of the valve plate 103 to achieve the switching effect, and ultra-high hardness material is selected as the raw material to improve the high pressure resistance.

[0025] The valve chamber 105 is fixedly connected to the outer shell 101 and is located within the outer shell 101; the inlet pipe 106 is connected to the valve chamber 105 and is located on one side of the semicircular groove 109 of the valve chamber 105; the drain pipe 107 is connected to the valve chamber 105 and is located on one side of the square groove 110 of the valve chamber 105; the support member 108 is slidably connected to the valve chamber 105 and is located on one side of the square groove 110 of the valve chamber 105; the valve chamber 105 is used to house the valve plate 103, which is disc-shaped and completely blocks the semicircular groove 109 when closed, cutting off water and air flow; when the valve plate 103 is open, water or air... The water flows in from one side of the inlet pipe 106 and out from the other side of the drain pipe 107. At this time, the support member 108 is housed in the square groove 110 of the valve chamber 105 and will not affect the rotation, opening and closing of the valve plate 103. When it is necessary to improve the high pressure resistance after the valve plate 103 is closed, the support member 108 is activated to press against the valve plate 103 and provide support, thereby improving the pressure resistance. By adding the support member 108 to strengthen the high pressure resistance of the valve plate 103, the problem of existing devices only improving the high pressure resistance by selecting ultra-high hardness materials, which mainly relies on the hardness of the material itself, and the structure of the device itself does not have an obvious effect on improving the high pressure resistance is solved.

[0026] Secondly, the support plate 111 is slidably connected to the valve chamber 105 and is located in the valve chamber 105; the support disk 113 is rotatably connected to the support plate 111 and is located on one side of the support plate 111; the screw 112 is threadedly connected to the outer shell 101 and fixedly connected to the support disk 113; when the valve plate 103 is open, water and air can flow through the through hole 118; when it is necessary to improve the high pressure resistance, the screw 112 is rotated to drive the rotating disk 102 and the support plate 111 to move, so that they are pushed to one side of the valve plate 103 and abut against the valve plate 103 to support it and improve the high pressure resistance.

[0027] Furthermore, the first telescopic tube 114 is fixedly connected to the valve chamber 105 and is located in the valve chamber 105; the second telescopic tube 115 is slidably connected to the first telescopic tube 114 and is located on one side of the first telescopic tube 114; the first telescopic tube 114 and the second telescopic tube 115 can prevent the screw 112 from being directly exposed to water flow and air flow and thus prevent corrosion, thereby improving the service life of the screw 112.

[0028] Finally, the pressure-resistant component 104 also includes a rubber pad 116 and a sealing ring 117. The rubber pad 116 is fixedly connected to the support plate 111 and is located on one side of the support plate 111. The sealing ring 117 is fixedly connected to the first telescopic tube 114 and is located in the first telescopic tube 114. The rubber pad 116 is located on the side of the support plate 111 near the valve, which can prevent the valve and the support plate 111 from directly contacting each other and causing wear. It can also prevent auxiliary sealing of the valve and prevent water and air from flowing to the other side. The sealing ring 117 can prevent water from entering through the gap between the first telescopic tube 114 and the second telescopic tube 115, thus protecting the screw 112.

[0029] When this device is used as a valve for a high-pressure pipeline, the valve chamber 105 is used to house the valve plate 103. The valve plate 103 is disc-shaped and, when closed, completely blocks the semi-circular groove 109, cutting off water and air flow. When the valve plate 103 is open, water or air enters from the inlet pipe 106 and exits from the drain pipe 107. At this time, the support member 108 is housed in the square groove 110 of the valve chamber 105 and does not affect the rotation, opening, and closing of the valve plate 103. When it is necessary to improve the high-pressure resistance after the valve plate 103 is closed, the support member 108 is activated to press against the valve plate 103, providing support and thus improving the pressure resistance. When the valve plate 103 is open, water and air flow through the through hole 118. Rotating the screw 112 moves the support disc 113 and the support plate 111, pushing them to one side of the valve plate 103 and pressing against it. The valve plate 103 provides support and improves its high-pressure resistance. The first telescopic tube 114 and the second telescopic tube 115 prevent the screw 112 from directly contacting water or air and being corroded, thus improving its service life. The rubber pad 116 is located on the side of the support plate 111 near the valve, preventing the valve from directly contacting the support plate 111 and causing wear. It also prevents the valve from being auxiliary-sealed, thus preventing water or air from flowing to the other side. The sealing ring 117 prevents water from entering through the gap between the first telescopic tube 114 and the second telescopic tube 115, protecting the screw 112. By adding a support member 108, the high-pressure resistance of the valve plate 103 is strengthened, thus solving the problem that existing devices only improve high-pressure resistance by selecting ultra-high hardness materials, and the high-pressure resistance mainly relies on the hardness of the material itself, while the structure of the device itself does not have a significant effect on high-pressure lifting.

[0034] The first pressure gauge 206 is fixedly connected to the control box 202 and communicates with the square groove 110 of the valve chamber 105; the second pressure gauge 207 is fixedly connected to the control box 202 and communicates with the semi-circular groove 109 of the valve chamber 105; the first pressure gauge 206 is used to monitor the pressure on the drain end side, and the second pressure gauge 207 is used to monitor the pressure on the inlet end side.
