Abstract
The invention discloses a stop valve with an overflow function. The stop valve comprises a valve body. A valve cavity is formed in the valve body. An overflow device is arranged at the outlet end of the valve body. The valve body is provided with a decompression channel for communication of the valve cavity and the overflow device. The overflow device comprises a safety valve shell, a guide rod and a junk ring. The safety valve shell is fixedly connected with the outlet end of the valve body. The guide rod is fixed in the safety valve shell. The junk ring is arranged on the guide rod in a sleeving manner and is in clearance fit with the guide rod. A spring is arranged between the junk ring and the safety valve shell and arranged on the guide rod in a sleeving manner. An overflow opening is formed in the bottom of the safety valve shell. According to the stop valve, when pressure of a system is too high, excess pressure can be released by squeezing the overflow device, so that local burst of the system is effectively avoided, and the safety of the system is improved.
Description
Technical field
The present invention relates to control valve field, be specifically related to a kind of stop valve with relief function.
Background technique
In China, stop valve is widely used in industries such as petroleum refining, long-distance transport pipes, chemical industry, papermaking, pharmacy, water conservancy, electric power, municipal administration, iron and steel, occupies very important status in national economy.But stop valve still has many technological deficiencies in the middle of prior art, be mainly manifested in when system pressure infinitely increases, unnecessary pressure cannot be discharged, thus easily cause system locally to burst, there is larger potential safety hazard.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of stop valve with relief function, this stop valve has decompression function, improves the Security of system, is easy to be promoted the use of widely.
