Abstract
The utility model discloses an electric closing device of a valve. The electric closing device comprises a valve body and a valve rod, wherein one side of the valve body is provided with an oil tank and an oil cylinder which are connected through an oil pipe respectively; an electromagnetic valve is arranged in the oil pipe; the end part of the piston rod of the oil cylinder is fixedly connected with the upper end of the valve rod; and a pressure sensor is arranged in the valve body, and is electrically connected with the electromagnetic valve through a control loop. The electric closing device has a reasonable structure and quick response, the valve can be closed quickly, safety accidents caused by excessive pressure inside the valve body are avoided, and safe running of other equipment is ensured effectively.
Description
Technical field
The utility model relates to a kind of electronic shutoff device of valve.
Background technique
Valve is the controlling component in the fluid delivery system, have by, adjusting, water conservancy diversion, prevent functions such as adverse current, voltage stabilizing, shunting or overflow pressure release.Valve can be used for flowing of all kinds fluids such as control air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.
Manually-operated gate mainly relies on the hand rotation valve rod to reach the purpose of throttle down; Move slowlyer, control accuracy is not high, and also having the shortcoming of electric valve is when the motor sudden power; Valve can not be closed rapidly; Therefore in case the valve internal pressure is excessive, the as easy as rolling off a log potential safety hazard of bringing can not be protected the safety of other equipment effectively.
The model utility content
The electronic shutoff device that the purpose of the utility model provides a kind of valve comes rapid-closure damper, ensures the safe operation of other equipment.
The technological scheme of the utility model is following:
A kind of electronic shutoff device of valve; Comprise valve body and valve rod; It is characterized in that: a side of said valve body is respectively equipped with fuel tank and the oil cylinder that links to each other through oil pipe, in the described oil pipe solenoid valve is installed, and the end of the piston rod of said oil cylinder is fixedly connected with the upper end of valve rod; Be provided with pressure transducer in the described valve body, described pressure transducer is electrically connected with solenoid valve through control loop.
The electronic shutoff device of described valve is characterized in that: pass through seal ring or packing seal between described valve body and the valve rod.
The beneficial effect of the utility model:
The utility model is rational in infrastructure, is swift in response, can rapid-closure damper, avoid generation owing to the excessive security incident that causes of valve inner pressure, and effectively ensured the safe operation of other equipment.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Referring to Fig. 1, a kind of electronic shutoff device of valve comprises valve body 1 and valve rod 2; One side of valve body 1 is respectively equipped with the fuel tank 3 and oil cylinder 4 that links to each other through oil pipe 5; Solenoid valve 6 is installed in the oil pipe 5, and solenoid valve 6 is in closed condition under normal conditions, and the end of the piston rod 7 of oil cylinder 4 is fixedly connected with the upper end of valve rod 2; Be provided with pressure transducer 8 in the valve body 1, pressure transducer 8 is electrically connected with solenoid valve 6 through control loop.
Seal through seal ring or filler 9 between valve body 1 and the valve rod 2.
When the pressure in pressure transducer 8 detects valve body 1 is excessive, through control loop conducting solenoid valve 6, oil pipe 5 mediations, oil cylinder 4 startup work, the piston rod 7 of oil cylinder 4 promotes valve rod 2 and moves down, rapidly Shuttoff Valve.
Claims (2)
