Abstract

The invention discloses a double-loop safe valve which comprises a valve body; screw plugs are arranged on openings on the left end and the right end of the valve body; a horizontal piston is arranged in the inner cavity of the valve body; the horizontal piston is clamped between the screw plugs on both ends; a spring is sleeved in the horizontal piston; a retainer ring is arranged in the middle of the horizontal piston; and a pair of installation holes are arranged at the upper part of the valve body. According to the double-loop safe valve, the structure is simple, the occupied space is small, the system integration degree is high and the service life is long; and the double-loop valve body is adopted, so that the working efficiency and the reliability are high.

Description

technical field [0001] The invention relates to a double-circuit safety valve, which belongs to the technical field of valves. Background technique [0002] The safety valve is used at the movable link with various machines to control and fix the movable displacement of the machine. At present, the more commonly used safety valves are mostly gas spring structures, which are prone to displacement during use, resulting in accidents. The safety valve is easily damaged and has a short service life, which increases the cost of the enterprise. SUMMARY OF THE INVENTION [0003] In order to alleviate the deficiencies and defects of the prior art, the purpose of the present invention is to provide a dual-circuit safety valve, which has the advantages of simple structure, small occupied space, high system integration, long service life, and high working efficiency by using a dual-circuit valve body. , Strong reliability. [0004] In order to achieve the above object, t...
