Abstract

The invention discloses a safe exhaust valve. The safe exhaust valve comprises a valve body, a valve cover, a housing, a first spring, a second spring, a first movable baffle, a second movable baffle, an air inlet, an air outlet, a release channel, an air pressure monitor control system, an inflating pump, a cylinder pushing device and a sealing ring. The bottom of the valve body is provided with the air inlet, the top of the valve body is provided with the valve cover, and the side wall of the valve body is provided with the air outlet; the first movable baffle capable of moving up and down is arranged in the axial direction of the valve body and above the air inlet; the second movable baffle is arranged above the first movable baffle; the release channel is arranged between the air outlet and the air inlet; one side of the air inlet is provided with an air pressure monitor which is connected with the inflating pump through the control system; the inflating pump is connected with the cylinder pushing device; the cylinder pushing device is composed of a piston and a piston rod. Compared with the prior art, the safe exhaust valve has the advantages of being simple in structure, still usable after the springs are damaged, and accordingly low in cost, capable of exhausting high-pressure gas, safe and reliable.

Description

technical field [0001] The invention relates to the field of valves, in particular to a safety exhaust valve. Background technique [0002] The safety valve is a special valve whose opening and closing parts are in a normally closed state under the action of external force. When the medium pressure in the equipment or pipeline rises above the specified value, it discharges the medium to the outside of the system to prevent the medium pressure in the pipeline or equipment from exceeding the specified value. . Safety valves are automatic valves, mainly used in boilers, pressure vessels and pipelines, to control the pressure not to exceed the specified value, and play an important role in protecting personal safety and equipment operation. The safety exhaust valve is a kind of safety valve, which is mainly used for the discharge of high-pressure gas. The safety exhaust valves currently on the market have a low safety factor and low exhaust efficiency. Contents of the invent...
