Description
Technical field
Gasoline line leakage valve self-closing device of the present invention, relates to a kind of gasoline feed pipe line accessory, is specially gasoline and leaks unhappy safety shutdown warning device.
Background technique
At present reveal because of gasoline the accident such as gasoline blast, environmental pollution causing and constantly occur, the generation of these accidents is all closed petrol cock or pipeline leakage and causes because forget.For existing problem in above-mentioned prior art, a kind of novel gasoline line leakage valve self-closing device of research and design, is very necessary thereby overcome existing problem in prior art.
Summary of the invention
In view of existing problem in above-mentioned prior art, the object of the invention is a kind of novel gasoline line leakage valve self-closing device of research and design.Exist in prior art in order to solve: leak and cannot close in time the problem such as gasoline blast and environmental pollution that main valve causes because of medium gasoline pipeline.
Technical solution of the present invention is achieved in that
Gasoline line leakage valve self-closing device of the present invention, is made up of fixed support, motor, control circuit; It is characterized in that fixed support is loaded on gasoline line, motor is housed on fixed support, on the axle of motor, shift fork is housed; The front end of shift fork is inserted in the rotary switch of valve; Control circuit is loaded on a support bracket fastened sidewall, and the control switch on control circuit is in fixed support outside; Receiver is loaded on fixed support; Warning light is installed on ground and obviously locates; Control circuit and warning light, receiver and fixed support on motor connect into loop by wire, control circuit is connected with external power supply; Multiple gasoline line traffic probes and signal transmitter are installed on respectively on each section of pipeline of medium gasoline pipeline; The inwall of valve scribbles leakage proof coating.
Shift fork of the present invention is many types of, and two shift fork rods are inserted in rotary switch.
On motor of the present invention, position limit switch is housed.
The present invention is loaded on medium gasoline pipeline pipeline main valve, and two shift fork rods of shift fork are inserted on the rotary switch of valve; Connect power supply, and several gasoline line traffic probes and signal transmitter are placed on respectively on each section of medium gasoline pipeline; In the time having medium gasoline pipeline to occur to leak, gasoline line traffic probe and signal transmitter are launched signal, receiver sends control circuit to after receiving signal, control circuit sends instruction to motor, motor rotation, shift fork is stirred rotary switch rotary closing valve, reaches after the stroke (setting stroke is that throttle down needs rotating cycle) of setting early stage, and motor cuts out; Complete the protection process of gasoline line leakage closing valve door, in this process, warning light flicker, the alarm on control circuit pipes, and prompting medium gasoline pipeline has the generation of leakage.Remove after leakage problem, open valve and get final product normal gasoline.
Advantage of the present invention is apparent, is mainly manifested in:
1, the present invention can close voluntarily in time gasoline line total valve, the economic loss of having avoided oil leak to cause in the time that leakage occurs medium gasoline pipeline;
2, motor of the present invention is equipped with position limit switch, has avoided continuing because of motor the motor damage that rotation causes;
3, the present invention simultaneously with sound pipe, the alarm mode such as warning light flicker, remind in time staff to overhaul, saved the time.
The present invention has novel structure, processes the advantages such as simple, with low cost, esy to use, safe and reliable, and it puts goods on the market in enormous quantities and will produce positive social benefit and significant economic benefit.
