Problems solved by technology

[0004] The invention provides a valve that is easy to maintain quickly, has the advantage of being easy to quickly replace the valve ball and the valve seat, and solves the problem of directly taking the valve seat and the valve ball out of the valve body when the valve is installed on the pipeline. It is very difficult. People need to use special tools to push the two valve seats in the valve body, so that the two valve seats are far away from each other, and the distance between the two valve seats is greater than the diameter of the valve ball to take out the valve ball. After the valve ball is taken out, continue to take out The valve seat, and before taking the valve ball and valve seat, it is necessary to disassemble the valve stem and valve cover. The disassembly process is very cumbersome, which makes the replacement process of the valve ball and valve seat very troublesome.

Abstract

The invention relates to the technical field of valve manufacturing, and discloses a valve convenient to maintain rapidly. The valve comprises a ball valve body, wherein the ball valve body comprisesa valve body, a valve cover and a valve rod, the bottom of the valve rod is provided with a replacement assembly located inside the valve body, the bottom of the valve body is provided with a lower valve groove for disassembling the replacement assembly, the replacement assembly comprises a middle sleeve, an inner sleeve and a ball valve, one side of the middle sleeve is in contact with an inner cavity of the valve body, the inner sleeve is sleeved in the middle sleeve, and the inner sleeve is in contact with the ball valve. According to the valve convenient to maintain rapidly, when the valveball and a valve seat need to be replaced, only a mounting assembly needs to be disassembled, the replacement assembly is taken out from the valve body, then the inner sleeve and the ball valve in the replacement assembly are taken out for replacement, replacement can be carried out without removing the valve from the pipeline, and the replacement process is simple and quick.

Description

technical field [0001] The invention relates to the technical field of valve manufacturing, in particular to a valve convenient for quick maintenance. Background technique [0002] The valve is a control device installed on the pipeline to control the flow of liquid or gas. The existing spherical valve mainly consists of a valve body, a valve seat, a valve ball, a valve stem and a valve cover. Rotate between two valve seats, if things go on like this, the sealing gasket between the valve ball and the valve seat is prone to wear, resulting in reduced sealing performance of the valve body and prone to leakage. At this time, the staff needs to take out the valve ball and valve seat for replacement. . [0003] However, it is very difficult for people to directly remove the valve seat and the valve ball from the valve body, because there are two valve seats in the existing spherical valve, and the ends of the two valve seats away from each other are directly embedded in the pass...
