Abstract
The utility model discloses an emergency cut-off valve for household gas, which is characterized by comprising a valve body, a seal casing, a seal spring, a seal rubber bowl, an iron core, an electromagnetic coil, a coil framework, a pull rod, a button, a magnetism conduction frame, a magnetism conduction partition sheet, a permanent magnet, a plastic base and a rubber seal gasket, wherein the seal casing is installed on the valve body, the rubber seal gasket is installed on the plastic base, the plastic base is installed at one end of the iron core, the pull rod is installed at the other end of the iron core, one end of the seal spring butts against the plastic base, the other end of the seal spring butts against the seal rubber bowl, the electromagnetic coil winds on the coil framework, the magnetism conduction partition sheet is arranged on the magnetism conduction frame, and the permanent magnet is sleeved on the magnetism conduction partition sheet in surrounding mode. The emergency cut-off valve for household gas has the advantages of long service life, low failure rate and good sealing performance, and reduces failure caused by damage of other accessories by using working pressure for helping sealing on the basis of the same kind products.
Description
Technical field
The utility model relates to a kind of domestic gas Emergeny Cutoff Valves, and specifically a kind of long service life, rate of fault are low, the domestic gas Emergeny Cutoff Valves of good airproof performance.
Background technique
At present, use cut-off valve and electricity on the family expenses Gas appliance to bump the air pressure that valve has only 0.5 ~ 1 kilogram, if anticyclonic the time; It leaks easily, and main cause is to use spring to press the abrasive disc sealing, failure phenomenon occurs after spring is long-time; So; Existing cut-off valve is short working life, and rate of fault is high, poor sealing.Main cause is that our air inlet is in the other direction, is that the circuitous resistance that arc control is arranged, same cut-off valve are not accomplish back-pressure, because there is not arc control just not explosion-proof.
Summary of the invention
The purpose of the utility model provides that a kind of long service life, rate of fault are low, the domestic gas Emergeny Cutoff Valves of good airproof performance.
The purpose of the utility model realizes through following technological scheme.
A kind of domestic gas Emergeny Cutoff Valves; It is characterized in that: said cut-off valve comprises valve body, can, Packing spring, sealer bowl, iron core, electromagnetic coil, circuit board antispark resistance, coil rack, pull bar, button, magnetic conduction framework, magnetic conduction partition, permanent magnet, plastic cement seat and rubber gasket; Can is installed on the valve body, and rubber gasket is installed on the plastic cement seat, and the plastic cement seat is installed in an end of iron core; Pull bar is installed in the other end of iron core; One end roof pressure of Packing spring is on the plastic cement seat, and the other end roof pressure is on the sealer bowl, and electromagnetic coil is wrapped on the coil rack; The magnetic conduction partition is arranged on the magnetic conduction framework, and permanent magnet rings is enclosed within on the magnetic conduction partition.
Said can is installed on the valve body through the stainless steel socket head screw.
Said electromagnetic coil is electrically connected a parallelly connected resistance in the coil, resistance plastic packaging with a control power line.
Said plastic cement seat is installed on the iron core through screw.
One button guard shield is installed on the said button.
The outer ring set one short-circuited conducting sleeve copper pipe of said iron core.
Be provided with terraced font corrugated rubber seal ring between said pull bar and the copper pipe.
One aluminum seal sheet is installed on the said permanent magnet.
One O-ring seal is installed between said can and the valve body.
The utility model compared with prior art has the following advantages:
The utility model is compared existing cut-off valve and is wanted high 2 ~ 3 times of air pressure, can reduce other accessory loss, and rate of fault is low, and its performance and life-span are that equivalents is more than 2 times.
Description of drawings
Fig. 1 is the structural representation of the utility model domestic gas Emergeny Cutoff Valves.
Embodiment
Below in conjunction with accompanying drawing the utility model domestic gas Emergeny Cutoff Valves is described in further detail.
As shown in Figure 1, the described domestic gas Emergeny Cutoff Valves of the utility model comprises valve body 1, can 2, Packing spring 6, sealer bowl 7, iron core 8, electromagnetic coil 9, two and connection circuit plate resistance, coil rack 10, pull bar 11, button 12, magnetic conduction framework 15, magnetic conduction partition 16, permanent magnet 18, plastic cement seat 20 and rubber gasket 21; Circuit board resistance together can arc control through plastic packaging; Can is installed on the valve body, and rubber gasket is installed on the plastic cement seat, and the plastic cement seat is installed in an end of iron core; Pull bar is installed in the other end of iron core; One end roof pressure of Packing spring is on the plastic cement seat, and the other end roof pressure is on the sealer bowl, and electromagnetic coil is wrapped on the coil rack; The magnetic conduction partition is arranged on the magnetic conduction framework, and permanent magnet rings is enclosed within on the magnetic conduction partition.Can is installed on the valve body through stainless steel socket head screw 3.Electromagnetic coil is electrically connected with a control power line 4.The plastic cement seat is installed on the iron core through screw 5.One button guard shield 14 is installed on the button.The outer ring set one short-circuited conducting sleeve copper pipe 13 of iron core.One aluminum seal sheet 17 is installed on the permanent magnet.One O-ring seal 19 is installed between can and the valve body.The utility model is compared existing cut-off valve and is wanted high 2 ~ 3 times of air pressure, can reduce other accessory loss, and rate of fault is low, and its performance and life-span are that equivalents is more than 2 times.The utility model air inlet makes the air pressure super large above the spring in the above, and sealing is super good, and double-layer seal is arranged, and carries signal voltage through alarm, and valve is opened for a long time, will close automatically when signal is arranged.The utility model connects by the valve body arrow shown in the figure carries out reverse air inlet.
