Background
The shut-off valve is also called a shut-off valve, and belongs to a forced sealing type valve, so that when the valve is closed, pressure must be applied to the valve clack so as to force the sealing surface not to leak. When a medium enters the valve from the lower part of the valve clack, the resistance which needs to be overcome by the operation force is the friction force of the valve rod and the filler and the thrust generated by the pressure of the medium, and the force for closing the valve is larger than the force for opening the valve, so that the diameter of the valve rod is larger, otherwise, the valve rod is in a bending fault. The connection mode is divided into three types: flange connection, screw thread connection and welding connection.
When the stop valve is used, the stop valve main body and the valve cover in the stop valve can be conveniently and rapidly installed and fixed through the bolts, but the bolt looseness or looseness phenomenon often occurs between the stop valve main body and the valve cover after the stop valve main body and the valve cover are installed, the stop valve cannot be effectively fastened, and further the looseness and the leakage of the joint between the stop valve main body and the valve cover are easily caused, so that the anti-leakage stop valve is provided for solving the problems.

In order to achieve the above purpose, the present utility model adopts the following technical scheme:
the utility model provides a stop valve of antiseep, includes the valve body, and the lower part both sides of valve body all communicate there is the connector, and the top of valve body is equipped with the valve gap, and the bottom fixedly connected with second ring flange of valve gap, and the top fixedly connected with first ring flange of top of valve body, and the top of valve body is equipped with four threaded rods, and all set up the screw thread groove that the cooperation threaded rod used on the first ring flange with the second ring flange, four bottom plates of upper portion outside fixedly connected with of valve body, and the top of four bottom plates all through elastic connection between the bottom of extension spring and four threaded rods respectively.
Preferably, a sealing gasket is arranged between the first flange plate and the second flange plate, and a hole matched with the threaded rod is formed in the sealing gasket.
Preferably, the four threaded rods are distributed in an annular array along the center of the first flange.
Preferably, the four bottom plates are distributed in an annular array along the center of the valve body.
Preferably, the four threaded rods are screwed with the first flange plate and the second flange plate.
Preferably, the bottom ends of the four threaded rods are connected with nuts through threaded screwing.
The utility model has at least the following beneficial effects:
when the anti-leakage stop valve is used, the two connectors on the valve body are used for mounting the stop valve, when liquid passes through the stop valve, the valve cover is impacted, when the threaded rod loosens, the threaded rod is pulled by the tension spring, the threaded rod is prevented from separating, the integrity of the stop valve is enhanced, leakage of liquid from the valve body to the valve cover is avoided, and compared with the prior art, the anti-leakage stop valve can be conveniently and rapidly mounted and fixed through bolts, but the loose or loose phenomenon of the bolts often occurs between the stop valve main body and the valve cover after the anti-leakage stop valve is mounted, and further the problem of loose leakage of the joint between the stop valve main body and the valve cover is easily caused.
