Detailed Description

The present invention will be described in further detail with reference to the following embodiments and accompanying drawings.

As shown in fig. 1-3, an integral instrument valve sequentially comprises a handle, a handle screw, an integral ball rod, a glan, a bracket nut, a disk spring, a pressure ring, an O-ring, a guide ring, a side ring, a valve seat and a valve body, wherein the valve body is integrally cast and internally provided with the integral ball rod, the glan, the disk spring, the pressure ring, the O-ring, the guide ring, the side ring and the valve seat;

the valve body is integrally cast, the horizontal two ends of the valve body are pipe joints, the outer part of the vertical end of the upper part of the valve body is connected with a bracket nut, a bracket is added on the bracket and the nut piece, the valve can be conveniently installed at a specified position and configured with different control devices, and the inner part of the valve body is connected with the flange; the integrated ball rod part is formed by integrally casting a rotating shaft and a ball body, the lower part of the integrated ball rod part is connected with the valve seat, the upper part of the integrated ball rod part is connected with the handle, and the upper part of the handle is provided with a switch indicator; the valve seat sealing part is integrally processed, the inner part of the valve seat sealing part is connected with the ball rod, and the outer part of the valve seat sealing part is connected with the side ring; in the upper sealing part of the ball rod, a guide ring at the lower part of the ball rod is connected with the valve seat, an O-shaped ring is arranged in the ball rod, the upper part of the ball rod is connected with a pressure ring, and a disc spring is arranged at the upper part of the pressure ring, so that the spring force can be continuously provided, and the continuous effectiveness of the sealing of the valve can be ensured; the two ends of the valve body, namely the connector form connected with the pipeline, can be in threaded connection, welded connection, quick-assembly connection and clamping sleeve connection, can meet the connection requirement of more than 95% of the current working condition occasions using the instrument valve, can be selected according to the actual requirement, and is not limited here.
