Problems solved by technology

In the prior art, in order to realize the safety protection and unloading function for the pipeline, it is necessary to use a solenoid valve and a safety valve to control whether the pipeline is in unloading through the energization of the solenoid valve, and when the solenoid valve is in the non-unloading In the load state, the safety protection function is realized through the safety valve, which not only increases the cost of use and the complexity of installation, but also increases the overall volume

Abstract

The invention discloses a safety valve which comprises a valve sleeve. A valve hole is formed in the valve sleeve. A through hole is formed in the position, at the bottom of the valve hole, in the valve sleeve. An opening P is arranged at the lower end of the through hole, and an opening T is arranged on the side face of the valve sleeve. A valve element is in sliding connection in the valve hole,and a magnetic guide sleeve is fixedly mounted at the upper end of the valve hole. A screw sleeve is fixedly arranged at the upper end of the magnetic guide sleeve. A coil is arranged on the outer circumference side face of the magnetic guide sleeve, and a pilot valve element, an armature and a first spring are arranged in the magnetic guide sleeve. By means of the safety valve, the functions ofunloading and safety protection can be switched through electric control, the structure is simple, the size is compact, and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of valves, and in particular relates to a safety valve. Background technique [0002] Safety valves are commonly used valves in industrial control and fluid pipelines. Safety valves are used to limit the maximum operating pressure in pipelines for safety protection. In the prior art, in order to realize the safety protection and unloading function of the pipeline, a solenoid valve and a safety valve are used to control whether the pipeline is in unloading through the energization of the solenoid valve, and when the solenoid valve is in the non-unloading In the load state, the safety protection function is realized through the safety valve, which not only increases the cost of use and the complexity of installation, but also increases the overall volume. Contents of the invention [0003] The purpose of the present invention is to provide a safety valve, which can not only realize the unloading function, b...
