Abstract

The invention discloses a buffer type ball valve easy to disassemble and assemble. The ball valve includes a ball valve seat. The ball valve seat is provided with a second communicating hole; the inner wall of the top and the inner wall of the bottom of the second communicating hole are provided with first grooves; a same bowl-shaped baffle plate with a through hole is slidingly installed inside the two first grooves; a same buffer spring is disposed inside the two first grooves; one end of the buffer spring is in contact with the inner wall of one side of one of the two first grooves; the inner wall of the top of one of the two first grooves is provided with a first communicating hole; a fixation block is movably installed inside the first communicating hole; the inner walls of two sidesof the first communicating hole are provided with clamping slots; both sides of the fixation block are provided with second grooves; and clamping pins are slidingly installed inside the second grooves. The ball valve can facilitate disassembly and installation of the buffer spring, facilitates replacement of the buffer spring, is simple in structure, and is convenient to operate.

Description

technical field [0001] The invention relates to the technical field of ball valves, in particular to an easily detachable buffer type ball valve. Background technique [0002] The impact resistance of ordinary ball valves is poor. When used in conjunction with safety valves, if the medium passing through the ball valve is a viscous liquid, it is easy for the medium to rush through the ordinary ball valve and enter the safety valve, thereby causing the viscous liquid to stick. The valve disc of the safety valve causes the safety valve to not be opened normally, and there is a potential safety hazard. After retrieval, the patent document with the authorization announcement number of CN202812382U discloses a ball valve seat with a buffer function, including a valve seat body, and a valve seat inside the valve seat. There is a valve cavity, the valve core is installed in the valve cavity, the valve seat is provided with a buffer cavity with a diameter larger than the diameter of...
