Abstract
The invention discloses an automatic gas-leakage valve closing device and relates to a gas delivery pipeline accessory, in particular to a safety closing and warning device for a gas-leakage valve. The automatic gas-leakage valve closing device is composed of a fixed housing, a motor and a control circuit, and is characterized in that the fixed housing is mounted on a gas pipeline, the motor is fixed in the fixed housing, shift forks are mounted on a motor shaft, and the front ends of the shift forks are inserted into a rotary switch of the valve. The control circuit is mounted on one side wall of the fixed housing, and a control switch on the control circuit is arranged outside the fixed housing. The control circuit, an alarm lamp, a receiver and the motor are connected to form a loop through leads, wherein the alarm lamp and the receiver are mounted outside the fixed housing, and the motor is arranged inside the fixed housing. The control circuit is connected with an external power source. A plurality of gas detecting and signal transmitting devices are respectively arranged at different positions of the pipelines. A vinylite glass flake mastic resin coating coats the inner wall of the valve. The automatic valve closing device has the advantages of novel structure, simplicity in processing, low cost, convenience in use, safety, reliability and the like.
Description
Technical field
Gas leakage Self-closing means of valve of the present invention, relates to a kind of gas conveying tube line accessory, is specially gas leakage valve safety shutdown warning device.
Background technique
The personnel that cause because of gas leakage are at present poisoning, and the accidents such as explosion of fire damp constantly occur, and the generation of these accidents is all closed gas valve or pipeline is revealed and causes because forget.Although gas leakage alarm has been installed by now a lot of families, in unmanned situation, the accident that gas leakage occurs is also a lot of at home.For existing problem in above-mentioned prior art, a kind of novel gas leakage Self-closing means of valve 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 gas leakage Self-closing means of valve of research and design.Gas leakage exists in prior art in order to solve: because cannot be closed personnel that coal gas main valve causes and the problem of property loss in time.
Technical solution of the present invention is achieved in that
Gas leakage Self-closing means of valve of the present invention, is made up of stationary housing, motor, control circuit; It is characterized in that stationary housing is loaded on gaspipe line, motor is equipped with in the inside of stationary housing, 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 sidewall of stationary housing, and the control switch on control circuit is in stationary housing outside; Control circuit connects into loop with the motor of the warning light, receiver and the stationary housing inside that are loaded on stationary housing outside by Dao County, and control circuit is connected with external power supply; Multiple coal gas is surveyed and sender unit is positioned over respectively pipeline everywhere; On valve inwall, scribble vinylite glass flake plasticine 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 gaspipe line main valve, and two shift fork rods of shift fork are inserted on the rotary switch of gas valve; Connect power supply, and several coal gas are surveyed and signal transmitter is placed on respectively the place of kitchen and gas-pipe line process; In the time having gas leakage, coal gas is surveyed and signal transmitter is 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 gas leakage throttle down, in this process, warning light flicker, the alarm on control circuit pipes, prompting gas leakage.Remove after leakage problem, open stationary housing, valve open can be recovered to normal use.
Advantage of the present invention is apparent, is mainly manifested in:
1, the present invention can occur to close voluntarily in time gaspipe line total valve while leakage at coal gas, has avoided personnel's life and mammon's loss;
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, effectively avoided the various losses that cause because of gas leakage.
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.
