Abstract

The invention discloses a buffering type stop valve with an automatic pressure relief function. The buffering type stop valve comprises a valve body, wherein a valve cover is arranged on the valve body, mutually vertical channels and valve flaps are arranged in the valve body, the valve flaps are mutually matched with the channels and are arranged in a cylinder body, exhaust holes are arranged on two sides of a cavity at the upper end of the cylinder body and are communicated with the channels, the valve flaps support against one end of a valve rod, and the other end of the valve rod extends out of a valve nut on the valve cover and then is connected with a handle. The invention has the advantages that the buffering type stop valve is arranged on a pipe, has two functions of a stop valve and a check valve simultaneously, also has the automatic pressure relief function so as to greatly exert a buffering function during starting and closing, has small friction and is convenient for the maintenance.

Description

Technical field [0001] The invention relates to a valve, in particular to a buffer type stop valve. Background technique [0002] In order to effectively cut off the fluid in the pipeline, valves are installed on the pipeline. Existing valves generally only have one function to stop or stop, the function is relatively single, the friction is large, and the maintenance is inconvenient. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a buffer cut-off valve with automatic pressure relief function. [0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a buffer type shut-off valve, including: a valve body, a valve cover is arranged on the valve body, and a channel that is perpendicular to each other and a valve disc that cooperates with the channel is arranged in the valve body , The valve clack is arranged in the cylinder body, and the vent holes are provided on b...
