Abstract

The invention discloses a high-temperature-resistant fast-assembly type three-way ball valve. The high-temperature-resistant fast-assembly type three-way ball valve comprises a valve body. By arranging a sealing ring I and a sealing ring II, double-sealing design is adopted among a rear cover, a fast-assembly cover, a left fast-connection cover assembly and a right fast-connection cover assembly and the valve body, the high sealing characteristic is achieved. By arranging the left fast-connection cover assembly and the right fast-connection cover assembly on the two sides of the valve body, the mounting limitation problem that bent pipe connection wires need to be additionally arranged in a pipeline of a conventional three-way valve is solved. Due to the reduction of accessories, the mounting space is greatly saved, and good mounting adaptability is obtained. A ball bowl sealing gasket is made of a high-temperature-resistant polytetrafluoroethylene material and is in an annular design, the contact surface of the ball bowl sealing gasket and a ball body is in a spherical surface shape, the thickness design of the ball bowl sealing gasket is based on four ball bowls which are arrayed on the circumference of the center plane of the diameter of the ball body, and mutual interference of the ball bowls is avoided. A proper shrinkage gap is reserved to determine the thickness size, so that the problem that the thin wall is easy to damage and the edge is easy to melt at high temperature due to the full-surrounding design of the ball body sealing ring of the conventional ball valve is solved.

Description

Technical field [0001] The present invention belongs to the technical field ball valve, particularly relates to a quick type of high temperature resistant ball valve. Background technique [0002] Ball valve with a T and L; T-shaped pipe allows three mutually orthogonal Unicom and off the third passage, from the division, a joining effect; L-type ball valve can connect two pipes mutually orthogonal, can not communicate with each other while maintaining the third conduit, dispensing only play the role; ball and gate valves belong to the same type, the difference between its closure member is a sphere, the sphere around the rotation center line of the body to achieve open and a closed species valve; valve in the pipeline is mainly used for cutting, distribution and change the direction of flow of the medium, a new type of ball valve is widely used. [0003] Ball appeared in the 1950s, with the rapid development of science and technology, continuous improvement of production process...
