Multi-purpose safety valve

Abstract

The invention discloses a multi-purpose safety valve. The multi-purpose safety valve is composed of a valve body, a diversion port, a pressure adjusting hole bolt, a chain pile, a valve opening rod base, a scrabbling rod base, a valve opening rod front window, a valve opening rod back window, a valve deck, a vent hole, a jacking bolt hole, a valve base, a hexagonal turn knob body, an external connector, a medium inlet, a valve element cylinder sleeve, a valve round ball, a jacking spring, a spring pressing disc, a pressing disc connecting rod, a clamping disc, a nut, a screw plug, a gear body,a sealing bolt, a quick opening scrabbling rod, a scrabbling rod shaft, a valve opening rod and a valve opening rod shaft. The multi-purpose safety valve can be suitable for different devices such asslurry pumping equipment, a pressure container, a boiler and an oil and gas storing tank and has the characteristics that the structure is simple and durable, the size is small, the valve element andthe valve can be replaced, the application range is wide, and the service life is long.

Description

technical field [0001] The invention relates to pumping mechanical equipment for slurry, putty, paint, liquid, etc., and various mechanical equipment fields such as pressure vessels, pressure pipes, boilers, oil and gas storage tanks, toxic chemical gas storage tanks, etc., specifically a multi-purpose safety valve . Background technique [0002] In the existing safety valves, they are generally less versatile and cannot be used for multiple purposes, and the structure is complex, there are many accessories, and the durability is poor. The closed part of the valve core is directly processed by the valve body. The material is easy to wear and leak. , Difficult to maintain, etc., the cover surface is used to seal, the contact surface is large, and a slight particle will cause leakage and poor sealing; especially the existing steam boiler safety valve, the valve core for medium circulation has a diameter of less than 3 cm. The outer diameter of its valve is more than 13 cm, th...

[0002] In the existing safety valves, they are generally less versatile and cannot be used for multiple purposes, and the structure is complex, there are many accessories, and the durability is poor. The closed part of the valve core is directly processed by the valve body. The material is easy to wear and leak. , Difficult to maintain, etc., the cover surface is used to seal, the contact surface is large, and a slight particle will cause leakage, and the sealing performance is poor; especially the existing steam boiler safety valve, the valve core for medium circulation has a diameter of less than 3 cm. The outer diameter of its valve reaches more than 13 cm, the ratio of the valve aperture to the valve body is 4 to 5 times, and the weight of the whole valve is more than 15 kg. It is basically used for one year and cannot be repaired due to leakage during the quality inspection, so a new valve has to be replaced. , causing unnecessary loss and waste. The main reason is that the decompression backflow safety device has not been applied to the existing building surface slurry, putty, paint scraping, spraying, caulking, and grouting mechanical equipment. It is a technical problem that is difficult to solve due to particles in the surface sealing structure of the valve
