DETAILED DESCRIPTION
[0021] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of the present application.
[0022] With reference to Figures 1-4 The utility model provides an embodiment: a valve that good sealing, including upper valve body 101, lower valve body 102, upper valve body 101 and lower valve body 102 are connected with each other through bolt nut, and the lower valve body 102 is fixedly connected with inlet water pipe 103 and outlet water pipe 104, and the inlet water pipe 103 and outlet water pipe 104 are all installed with the connecting flange, and the upper valve body 101 and lower valve body 102 are all equipped with the installation groove, and the installation groove is equipped with sealing washer 402, and the middle part of sealing washer 402 is equipped with the passageway for liquid circulation, and the top of upper valve body 101 is fixedly connected with valve seat 105, and valve seat 105 is threadedly connected with control rod 106, and the upper portion of control rod 106 is installed with control handle, and top sealing sleeve 405 is equipped between control rod 106 and valve seat 105, and the lower end of control rod 106 is rotatably connected with connecting sleeve 404, and the lower portion of connecting sleeve 404 is fixedly connected with connecting plate 401, and the lower portion of connecting plate 401 is fixedly connected with sealing valve plate 403, and sealing valve plate 403 is located between two sealing washers 402, and sealing valve plate 403 is closely attached with two sealing washers 402, and the outside of upper valve body 101 is installed with upper communication casing 2, and upper communication casing 2 is fixedly connected with upper air bag 201, and the number of upper air bag 201 and lower air bag 301 is two, and upper air bag 201 is located above lower air bag 301, and upper air bag 201 extends into the upper interior of sealing washer 402, and the outside of lower valve body 102 is installed with lower communication casing 3, and lower communication casing 3 is fixedly connected with lower air bag 301, and lower air bag 301 extends into the lower interior of sealing washer 402, and upper communication casing 2 and lower communication casing 3 are all equipped with gas filling end 5, and gas filling end 5 includes gas filling pipe, and the gas filling pipe is threadedly connected with gas filling cover.
[0023] The inlet pipe 103 and outlet pipe 104 are used to connect with external water pipes for water inflow and outflow. The handle on the control rod 106 drives the control rod 106 to rotate, which in turn moves the connecting sleeve 404, connecting plate 401, and sealing valve plate 403 downwards. This allows the sealing valve plate 403 to make tight contact with the sealing gasket 402, achieving a sealing state. Conversely, the sealing valve plate 403 can move upwards, opening the valve and allowing liquid to flow. After prolonged use, the gas filling cap is opened, and gas is injected into the upper connecting housing 2 and lower connecting housing 3 through the gas filling pipe. The gas enters the upper air bladder 201 and lower air bladder 301, increasing the volume of the sealing gasket 402. This ensures that the sealing gasket 402 fits tightly against the upper and lower valve bodies 101, improving the sealing performance of the sealing gasket 402 and the upper and lower valve bodies 101, thus enhancing the overall sealing performance and service life. The system is highly reliable in use. By incorporating the sealing gasket 402, upper airbag 201, and lower airbag 301, air can be injected into the upper airbag 201 and lower airbag 301. This increases the volume of the sealing gasket 402, thereby increasing the pressure between the sealing gasket 402 and the upper and lower valve bodies 101, improving sealing performance, and thus extending the overall service life. The system is highly reliable in use.
[0024] Working principle: The inlet pipe 103 and outlet pipe 104 are used to connect with external water pipes for water inflow and outflow. The handle on the control rod 106 drives the control rod 106 to rotate, which in turn moves the connecting sleeve 404, connecting plate 401, and sealing valve plate 403 downwards. This allows the sealing valve plate 403 to make tight contact with the sealing gasket 402, achieving a sealing state. Conversely, the sealing valve plate 403 can move upwards, opening the valve and allowing liquid to flow. After prolonged use, the gas filling cap is opened, and gas is injected into the upper connecting shell 2 and lower connecting shell 3 through the gas filling pipe. The gas enters the upper air bladder 201 and lower air bladder 301, increasing the volume of the sealing gasket 402. This ensures that the sealing gasket 402 fits tightly against the upper and lower valve bodies 101, improving the sealing performance of the sealing gasket 402 and the upper and lower valve bodies 101, thus enhancing the overall sealing performance and service life. It is highly reliable in use.
