Corniform regulating valve

Abstract

The invention discloses an angular adjusting valve, comprising a valve body, a valve seat, a valve core, a valve rod, and a valve cover. The valve body is internally provided with a valve chamber; the side part, the lower part and the upper part are respectively provided with an inlet, an outlet and a guide sleeve mouth; the valve rod is arranged on the upper part of the valve body; a guide sleeve is fixed inside the guide sleeve mouth; the lower end of the valve rod is connected with the valve core which motions in the guide sleeve; the upper end of the valve rod passes through out of a stuffing box on the valve cover; the lower end of the valve rod is a connecting head; the valve core is fixed on the connecting head; the surface of the connecting head is provided with a plurality of garbage troughs intermittently. By adopting the technical proposal, the angular adjusting valve of the invention has a self-cleaning function and can avoid that the garbage grains are blocked and abraded in the guide sleeve.

Description

technical field [0001] The invention relates to a regulating valve, in particular to an angle regulating valve used for the control and regulation of black water and slag water in a coal chemical system. Background technique [0002] Angle regulating valve has a simple flow path and self-cleaning performance. It is suitable for unclean media, such as the control and regulation of black water and slag water in coal chemical industry systems. Therefore, angle regulating valve is also commonly known as black water regulating valve. [0003] At present, the widely used angle regulating valve is composed of a valve body, a valve seat, a valve core, a valve stem, a valve cover, a packing and a packing pressure plate and an actuator. The side, bottom and top of the valve body 08 are the inlet 082, the outlet 083, and the guide bushing 084 which communicate with the valve cavity 081 respectively. The outlet 083, the guide hole 084, and the stuffing box 131 are on a vertical line, t...

Problems solved by technology

However, the valve seat 07 of this angle-shaped regulating valve is installed in the outlet 083 of the valve body 08 through threads with a special tool, which causes extremely inconvenient product assembly and disassembly, on-site maintenance, etc., and the medium is easy to pass through the valve when the valve is closed. Seat thread leakage, resulting in valve leakage will continue to increase

In addition, due to the harsh working conditions of the angle regulating valve, the high-pressure medium is likely to cause erosion of the valve core, valve seat, and valve body. In addition, the garbage particles adhering to the valve core are easily brought into the guide sleeve by the valve core. Inside, the garbage particles are located in the gap between the guide sleeve and the valve core, which will cause the valve core to be stuck and wear the valve core, which will easily affect the normal use of the valve and shorten the service life of the valve
