Embodiment Construction

[0012] As shown in the figure, 1. Lower connection joint, 2. Valve body, 3. O-ring, 4. Adjusting butterfly spring, 5. Enhanced PPL synthetic sealing material, 5. O-ring, 6. Ball valve core, 7. Gasket, 8. O-ring, 9. Packing, 10. Valve stem, 11. Hex bolt, 12. Bracket, 13. Pneumatic control device.

[0013] A pneumatic actuator controls a high-pressure ball valve. The valve body is a horizontal thick cylindrical cylinder. The lower part of the ball valve core can be connected with a convex post, and a concave ball arc is prepared with a cylindrical hole matching the convex post.

[0014] The valve body, upper cover and ball seat sealing ring are all made of block cast steel, and are fixed with hexagon socket head screws.

[0015] The thick cylinder and the whole cylinder adopt a forged structure to ensure the overall strength of the valve body. The length of the entire ball valve is only 1 / 2 of that of the ordinary globe valve; the combination structure of reinforced PPL syntheti...

Abstract

Disclosed is a pneumatic actuator control high pressure ball valve. The ball valve comprises a lower connecting joint, a valve body, a base support, an upper cover, an O-shaped sealing ring, an adjusting butterfly spring, a reinforced PPL synthetic sealing material, a spherical valve element, a sealing gasket, packing, a valve rod, hexagon bolts, a bracket, a pneumatic control device and a ball base sealing ring; the valve body is a transverse thick cylinder, the thick cylinder of the valve body is provided with an inlet and an outlet of the valve, and the inlet and the outlet are connected with end joints; the spherical valve element is arranged in the center of the valve body, left and right ball base sealing rings communicated with the inlet and outlet are located at the inlet and outlet which are formed in the left and right portions of the valve body, and the bracket is arranged on the combined packing and fixed to the upper cover of the valve body through screws at the upper end;the pneumatic control device is arranged above the bracket; the pneumatic control device outputs rotational driving torque to the valve rod.

Description

Technical field: [0001] The invention relates to a ball valve, especially a high-pressure ball valve, which is suitable for a pneumatic actuator to control a high-pressure ball valve used in petroleum, chemical, fertilizer, pesticide, chemical fiber, papermaking, sugar, food, power station and other industrial sectors. Background technique: [0002] With the rapid development of my country's national economy, in my country's petroleum, chemical, fertilizer, pesticide, chemical fiber, papermaking, sugar, food, power station, and other industrial sectors, as well as pipeline control systems in agriculture and even living facilities, a variety of specifications are used. Valves are used to control the system, and more and more valves are needed to control the liquid flow pipeline. It is necessary to solve the shortcomings of the ordinary ball valve body in terms of wear resistance, high pressure resistance and sealing. High-pressure ball valves are especially used to cut off var...
