Abstract
A household gas leakage alarming safety valve, which cuts off the air supply automatically when a gas leakage happens. The utility model unlocks the mini type switch of the safety valve through outputting a power lead by an annunciator, makes an electromagnet work in condition of energization, then drives the transmission shaft move to the valve body, and pushes a moving cover towards to the outlet of the valve body through the ram of the transmission shaft, so that closing the valve and cutting the sir supply are fulfilled. 1. A socket is arranged on the transmission shaft. When the valve closed, one end of a small ram with no electricity enters into the socket; the other end looses an adherent point of the tiny switch, turns on the electromagnet power, and keeps the valve in closed, then fulfills the self-lock of the transmission shaft.
Description
Technical field
The utility model relates to when combustion gas takes place to leak, in the time of by alarm equipment alarm, connect the power supply that alarm connects electromagnet, promote transmission shaft and renovate, valve closing is cut off a kind of household gas leakage warning safety valve of source of the gas by transmission shaft connecting rod releasing activity.
Background technique
It is reported that known gas solenoid valve is to promote piston shaft by electromagnet the air outlet of valve body is closed, and reaches and cuts off the source of the gas purpose.When the situation of valve closing, electromagnet is all the time all in charged work.In the environment of gas leakage was arranged, the long-term charged work of coil made magnet spool heating, short circuit cause damage easily.
Summary of the invention
In order to overcome existing gas with the easy damnous deficiency of the long-term charged work of solenoid valve, the utility model provides a kind of household gas leakage warning safety valve, this valve can not only cut off source of the gas when combustion gas is revealed automatically, and when cutting off source of the gas the power supply of tripping magnet, and transmission shaft realized auto-lock function.Thereby improved the safety reliability of household gas leakage warning safety valve more.
The beneficial effects of the utility model are when combustion gas is revealed people or unmanned on the scene can both timely source of the gas the cut-out automatically to be arranged.And this valve all need not long charged work, simple in structure, reliable performance under Chang Kai or normally closed state.
Figure of description is the structural drawing of household gas leakage warning safety valve when closing.When normally using gas appliance at ordinary times, if with hand with outwards 1 centimetre of the pulling of the movable block on electromagnet top, this valve promptly enters normally open.
The household gas leakage warning safety valve mode of connection: a wherein connection microswitch of the power line of alarm output wherein, another point of microswitch connects wherein the end of a thread of an end of electromagnet coil again, and the other end the end of a thread of electromagnet coil connects the other end of alarm out-put supply line again.When family expenses gas leakage alarm safety valve is in when often opening, the electromagnet circuit of this valve just forms a loop, in alarm equipment alarm, connect electromagnet power supply, electromagnet enters charged working state, and promotes transmission shaft, renovate by transmission shaft connecting rod releasing activity, safety valve cuts out.The utility model solves the used technological scheme of its technical problem: when alarm is connected household gas leakage warning safety valve lead, and make electromagnet energising work by microswitch, doing the promotion transmission shaft again moves to valve body, by the transmission shaft connecting rod movable flip is discharged, press to the valve body air outlet.Rubber pad and the air outlet close proximity that renovate this moment, thus reach throttle down.One groove is arranged on the transmission shaft, and one of small rod of outage enters in the transmission shaft groove when throttle down, and the microswitch contact is thrown off in the other end of outage small rod, and the power supply of tripping magnet still is in outage work when making safety valve in off position.For preventing the transmission shaft play, during the groove of outage small rod on deviating from transmission shaft, the other end of outage small rod starts microswitch again, connects electromagnet power supply, makes valve be controlled at closed condition firmly.Realize the transmission shaft auto-lock function, thereby guaranteed the reliability that safety valve uses.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified, principle assumption diagram of the present utility model is made up of 7 parts: (1) Safety valve body (2) movable flip (3) transmission shaft connecting rod (4) transmission shaft (5) microswitch (6) outage small rod (7) electromagnet
Embodiment
The lead that connects household gas leakage warning safety valve when alarm makes electromagnet (7) energising work by microswitch (5), promotes transmission shaft (4) drive transmission shaft connecting rod (3) valve body air outlet, throttle down are pressed in movable flip (2) release.Transmission shaft (4) has a groove, when throttle down, outage small rod (6) enters in transmission shaft (4) groove, and tripping magnet (7) power supply is thrown off with microswitch (5) contact in outage small rod (6) other end, still is in outage work when making this valve in off position.Deviate from the groove of transmission shaft (4) for preventing transmission shaft (4) play outage small rod (6), the other end of outage small rod (6) starts microswitch (5) again, connect electromagnet (7) and make valve firmly be controlled at closed condition, realized transmission shaft (4) auto-lock function.Thereby guarantee the reliability that safety valve uses.
Claims (2)
1. household gas leakage warning safety valve, comprise Safety valve body, movable flip and transmission shaft connecting rod and transmission shaft in the Safety valve body, connect the microswitch and the electromagnet of work of electromagnet, the end hinge that it is characterized in that the transmission shaft body has the outside thread that matches with the threeway outlet internal thread of Safety valve body (1) and is connected sealing, its the other end is connected with electromagnet by screw, be connected with movable flip (2) sealing at Safety valve body (1) inner outlet place by pivot pin, and the transmission shaft connecting rod (3) that passes through on the movable flip (2) is connected with transmission shaft (4), the other end of transmission shaft (4) is connected on the electromagnet (7) by the iron hoop pin, is provided with outage small rod (6) on the transmission shaft body.
2. household gas leakage warning safety valve according to claim 1, the small rod (6) that it is characterized in that cutting off the power supply is in the pilot hole that is contained on the transmission shaft body, and match with the groove of transmission shaft and to be connected or to throw off groove and connect, on outage small rod (6), be with spring, elastic force by internal thread cover Regulation spring is also fixing, and the other end of outage small rod (6) is connected or does not connect with microswitch (5).
