Technical Field

The utility model relates to a governing valve technical field especially relates to a governing valve device.

Background

With the rapid development of information technology and the continuous improvement of industrial intelligence, the valve is used as a terminal execution mechanism for controlling the movement of fluid in a pipeline, the limitation of self functions is gradually changed, and the valve is rich in a more brand new concept, while domestic valve enterprises are developing along a new direction of new requirements on energy conservation, environmental protection, intelligence, small volume, light weight, long service life and the like.

At present, China has great potential in the fields of petroleum, natural gas, electric power, chemical industry, environmental protection and the like, and the environment related to the fields is mostly a high-pressure environment, so the demand for the regulating valve is great, but the traditional regulating valve only has one valve core, the sealing performance is poor, the abrasion consumption between the valve core and the valve body is great, the damage and replacement rate is high, and the service life is short.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome above-mentioned not enough, provide a governing valve device, increase the leakproofness, reduce wear, increase of service life.

The purpose of the utility model is realized like this:

the regulating valve device comprises a valve rod, a valve body and a valve core, wherein the valve rod is arranged in the valve core, the valve core is arranged on the valve body, an end cover is arranged at the upper end of the valve body, a position device is arranged on the end cover, the valve rod penetrates through the position device and the end cover, and connecting flanges are arranged on two sides of the valve body.

The lower end of the end cover is provided with a positioning flange, and the valve rod is fixedly connected with the end cover through the positioning flange.

The utility model provides a regulating valve device, the flange of valve body one side is connected with the valve body through hexagon socket head cap screw and flat pad, the flange of valve body opposite side is connected with the valve body through fluting butt holding screw, and the junction is equipped with O type circle.

A valve core is arranged on a valve body through an inner hexagonal countersunk head screw.

The total length of the fixed connecting flange is not less than 200 mm.

The utility model provides a governing valve device, the end cover passes through hexagon socket head cap screw to be fixed on the valve body, hexagon bolt is no less than 4.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model relates to a governing valve device is because the valve rod runs through position ware and end cover to be closely setting up with valve body, case, make the direction of case reliable and more stable, guaranteed the axiality of case and disk seat, the utility model discloses a flange of valve body one side passes through hexagon socket head cap screw and flat pad and is connected with the valve body, and the flange of valve body opposite side passes through fluting butt holding screw and is connected with the valve body, and the junction is equipped with O type circle, has avoided the wearing and tearing between case and the disk seat, has prolonged the life of valve rod, case and valve body.
