Description

Technical Field

[0001] The utility model relates to the technical field of valves, and more particularly to a valve that is easy to disassemble and install. Background Art

[0002] Valves are control components in fluid conveying systems, used to open and close pipelines, control flow direction, and adjust and control the parameters of the conveying medium (such as temperature, pressure, and flow). Valves can be divided into shut-off valves, check valves, regulating valves, etc. according to their functions. They have functions such as shut-off, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief. Valves are widely used to control the flow of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. Valve control can be achieved through a variety of transmission methods, such as manual, electric, hydraulic, pneumatic, etc. These control methods can act according to predetermined requirements under the action of pressure, temperature or other forms of sensor signals, or simply open or close without relying on sensor signals.

[0003] During the use of the valve, the frequency of opening and closing is relatively high, so the opening and closing parts inside the valve are prone to malfunction. When the opening and closing parts are damaged and need to be replaced, the valve stem needs to be removed for easy replacement, but the existing valves are troublesome to disassemble; secondly, the existing valves are prone to sealing problems after disassembly and installation, which makes the disassembly and installation of the valves less efficient.

The top of the packing bushing 203 is movably connected to a pressure plate 204, and the outer side of the pressure plate 204 is movably connected to a sealing ring 205. By installing the packing bushing 203 on the inner top of the connecting piece 2, fixing the position of the packing bushing 203 by the pressure plate 204, and then sealing the outer side of the pressure plate 204 by the sealing ring 205, the bottom of the valve cover 3 fixes the position of the sealing ring 205 and the pressure plate 204, which is beneficial to improving the sealing performance of the connecting piece 2 after disassembly and installation.

[0021] In a preferred embodiment, the valve cover 3 includes a cover body 301, and the bottom middle part of the inner part of the cover body 301 is movably connected to a bearing 302, and the top of the cover body 301 is movably connected to evenly distributed fixing bolts 303, and the bottom of the fixing bolts 303 is movably connected to a fixing nut 304. The top mounting plate of the connector 2 is fixed to the valve cover 3, and the bottom mounting plate of the connector 2 is fixed to the valve seat 1 by the cooperation of the fixing bolts 303 and the fixing nuts 304. The connector 2 and the valve seat 1 can be quickly disassembled by removing the fixing bolts 303, which is conducive to the rapid disassembly and installation of the connector 2.

[0022] In a preferred embodiment, the top and bottom of the connection body 201 are fixedly connected with mounting plates, and the mounting plates are respectively connected to the valve seat 1 and the valve cover 3 through the cooperation of fixing bolts 303 and fixing nuts 304 .

[0023] In a preferred embodiment, the transmission device 4 includes a handle 401 , a valve stem 402 is fixedly sleeved in the middle of the handle 401 , a bearing 302 is movably sleeved on the outer side of the valve stem 402 near the top, and a thread is provided on the outer bottom of the valve stem 402 .

[0024] In a preferred embodiment, the outer bottom of the valve stem 402 is movably connected to the gate plate 403, and a threaded hole is opened in the middle of the top of the gate plate 403, and the threaded hole and the valve stem 402 are adapted to each other. The bottom of the gate plate 403 is an arc structure, and the valve stem 402 and the gate plate 403 are connected by threads. By disassembling the connecting piece 2, the threaded transmission distance of the valve stem 402 is increased, and the transmission limit of the gate plate 403 is cancelled. The gate plate 403 can be quickly removed by threaded transmission, which is conducive to the rapid replacement and maintenance of the gate plate 403.

[0025] In a preferred embodiment, the valve seat 1 includes a valve seat body 101, and flanges 102 are fixedly connected on both sides of the valve seat body 101. An opening and closing groove 103 is opened in the middle of the interior of the valve seat body 101.

A dynamic sealing ring 104 is movably connected to the middle of the outer side of the opening and closing groove 103. The bottom height of the dynamic sealing ring 104 is the same as the height of the connection between the arc-shaped bottom and the side after the gate plate 403 rises and opens.

[0026] The working principle of the present invention is as follows: the top mounting plate of the connector 2 is fixed to the valve cover 3 by the cooperation of the fixing bolts 303 and the fixing nuts 304, and the bottom mounting plate of the connector 2 is fixed to the valve seat 1. The connector 2 and the valve seat 1 can be quickly disassembled by removing the fixing bolts 303, which is conducive to the rapid disassembly and installation of the connector 2. When disassembling, the handle 401 is turned to make the valve stem 402 rotate inside the cover body 301 through the bearing 302. The outer bottom thread of the valve stem 402 and the top threaded hole of the gate plate 403 are adapted to each other, so that the gate plate 403 is threadedly driven to rise along the valve stem 402. After the gate plate 403 rises, the height of the connection between the arc bottom and the side is the same as the bottom height of the dynamic sealing ring 104. It is beneficial to prevent the liquid inside the valve seat 1 from entering the movable groove 202 through the cooperation of the side of the gate plate 403 and the dynamic sealing ring 104 after the gate plate 403 rises. By disassembling the connecting piece 2, the threaded transmission distance of the valve stem 402 is increased, and the limit of the gate plate 403 transmission is cancelled. The gate plate 403 can be quickly removed through threaded transmission, which is beneficial to quickly replace and repair the gate plate 403. By installing the packing bushing 203 on the inner top of the connecting piece 2, fixing the position of the packing bushing 203 by the pressure plate 204, and then sealing the outside of the pressure plate 204 by the sealing ring 205, the bottom of the valve cover 3 fixes the position of the sealing ring 205 and the pressure plate 204, it is beneficial to improve the sealing performance of the connecting piece 2 after disassembly and installation.
