Description

Stop valve for high-pressure regulation by using bevel gear

Technical Field

The utility model relates to a stop valve, concretely relates to use bevel gear to carry out high pressure adjusting's stop valve.

Background

The stop valve is also called stop valve, belonging to forced sealing type valve, when the valve is closed, it must apply pressure to valve core to force sealing surface not to produce leakage.

The valves on the pipelines are various, wherein the stop valve is a commonly used valve and is used for controlling the cut-off or flow regulation of various flowing media such as air, water, steam and the like, the opening and closing part of the stop valve is a plug-shaped valve seat, the sealing surface is a plane or a conical surface, and the valve seat moves linearly along with the lifting of the valve rod. The existing stop valve mainly comprises a valve body, a valve cover, a valve rod and a valve seat, wherein a sealing gasket is arranged between the valve seat and the valve body and used for sealing a medium and avoiding the leakage of the medium along a gap between the valve seat and the valve body, but because the flowing medium in the valve often has higher pressure and the pressure generally acts on a joint (hereinafter referred to as a sealing joint surface) between the sealing gasket and the valve seat and between the sealing gasket and the valve body, the excessively high pressure of the flowing medium can form a separation effect on the sealing joint surface, so that the sealing joint surface tends to generate a gap, the flowing medium is easy to permeate outwards through the sealing joint surface, and the sealing performance is further influenced.

The existing stop valve is poor in high-pressure liquid sealing effect, a gap is easily generated at a sealing joint, and meanwhile, the valve seat can be seriously abraded when a regular switch is used, so that the gap cannot be effectively sealed, the stop valve is difficult to adjust the medium flow under a high-pressure state, the stop valve is slow in flow adjusting and stopping effects, and the medium loss and waste are caused.
