Abstract
A novel high-temperature and high-pressure ball valve comprises a valve body. A fluid inlet and a fluid outlet are arranged on the valve body. The center of the ball body is provided with a ball body which is connected with a valve rod. A sealing device arranged in the contacting position, which is located at the fluid inlet end, of the ball body and a fluid passageway is pressed tightly through a spring. A sealing device is arranged inside the valve body located in the connecting position, which is located at the fluid outlet end, of the ball body and the fluid passageway. A valve deck is fixedly connected with a middle valve body into a whole through a screw column. A support is fixedly connected on the periphery of the valve rod on the upper portion of the valve body. The support is fixedly connected with a pneumatic actuator which is in transmission connection with the valve rod. Each sealing device is composed of a metal gasket, a metal supporting ring, a separating ring, and a carbon graphite ring. Both the valve body and the valve deck are casting bodies. The novel high-temperature and high-pressure ball valve is a pipeline valve suitable for high-temperature and high-pressure fluid, abrasion resistant and capable of adapting to poor utilization environment.
Description
Technical field
The utility model relates to a kind of ball valve, particularly a kind of new type high temperature high-pressure ball valve.
Background technique
General in the market ball valve is not long working life, and fluid and some that particularly can not bear HTHP for a long time have corrosive fluid.
The model utility content
To the deficiency of existing technology, the utility model provides a kind of new type high temperature high-pressure ball valve.
To achieve these goals, the utility model solution technological scheme that its technical problem adopted is: a kind of new type high temperature high-pressure ball valve comprises valve body; Valve body is provided with stream socket, is provided with spheroid in the center portion of valve body, and spheroid is connected with valve rod; Seal arrangement in fluid input end spheroid and contacting point, fluid passage is used spring compression; In the valve body of fluid outlet spheroid and contacting point, fluid passage, be provided with seal arrangement, valve gap is connected to one through double-screw bolt and middle valve body, around the valve rod on valve body top, is fixedly connected with support; Be fixedly connected with pneumatic actuator on the support, pneumatic actuator and valve rod are in transmission connection.
Described seal arrangement is made up of metal washer, metallic support circle, cage ring, carbon graphite circle.
Said valve body, valve gap all are body of castings.
The beneficial effect of the utility model: this new type high temperature high-pressure ball valve can be applicable to the pipeline valve of the fluid of high-temperature, High Voltage, and is erosion-resisting, can adapt to more abominable Environmental Conditions.
