Problems solved by technology

[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

Embodiment 1

[0018] Such as figure 1 As shown, the multipurpose safety valve of the present invention can be installed horizontally on the upper part of the material box wall of pumping machinery such as slurry, putty, and paint after the working pressure is adjusted, and the device is fixed by the external joint 022 and then transported with the slurry, putty, and paint. The mechanical feeding pipe is connected by a three-way connection, and the diversion port 011 faces the material box. During the feeding process of the machine, if the feeding pipe is blocked or the front tool is temporarily closed and no feeding is required, the slurry in front of the valve ball 04 in the feeding pipe The pressure of the material, putty and paint increases, and when the pressure is stronger than the pressure of the top pressure spring 05, the pressure of the slurry, putty and paint presses the ball 04 of the valve core to separate from the cylinder liner of the valve core, and the slurry, putty and paint...

Embodiment 2

[0020] Such as figure 1 As shown, the multi-purpose safety valve of the present invention is connected with the air storage tank of the air compressor or a separate high-pressure air storage tank, and the gear body 061 is moved with a screwdriver, and the required working pressure is adjusted through the pressure gauge indication, so that the pressure can be kept constant. Balanced, play a safe explosion-proof role.

Embodiment 3

[0022] Such as figure 1 As shown, the multi-purpose safety valve of the present invention after being checked and debugged by the relevant quality inspection department is connected to the toxic chemical gas storage tank. When the pressure exceeds the specified value, the valve ball 04 will automatically open, and the toxic chemical gas will be transferred to the empty tank of harmful chemical gas through the diversion port. When the pressure of the toxic chemical gas is within the specified value range, the valve ball 04 will be automatically closed, so as to achieve explosion-proof , Anti-leakage safety protection.

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...
