Description
Technical field
The utility model relates to a kind of liquid gas storage tanks to depressurize leakage easing valve, excessively high using environment temperature is met in liquid gas storage tank
When automatic disconnection liquefied gas tank, can also liquefied gas tank leak concentration reach setting value when, can also be with hand by electronic closing valve
It is dynamic to close valve.
Background technique
Liquid gas storage tank generally uses in urban and rural residents' house, part enterprises and institutions, Kitchen at present.But it liquefies
Vapour has inflammable and explosive characteristic, so the harm major embodiment occurred is both ways: 1. liquefied gas tank before fire occurs
Leakage may cause the danger of personnel's poisoning and explosion.2. after fire occurs, burning caused by the leakage of liquefied gas tank, explosion are caused
Expand loss.In the use process of liquefied gas tank, aging and the carelessness used due to gas utensil etc. cause letting out for liquefied gas tank
Frequent Accidents are leaked, are very important so closing fuel gas supply when liquefied gas tank leaks.
In the case of fire, it closes liquefied gas tank air valve and needs a few minutes clock time, people cannot connect again after fire generation
Nearly liquid gas storage tank closes valve, and liquefied gas tank equally can also be caused to leak on fire and explode, every year because liquid gas storage tank improper use is sent out
Raw fire causes huge loss to life, the property of the people.
The patent of the patent No. 201510619086.0 provides a kind of liquid gas storage tank decompression easing valve, sees Fig. 5, liquefying
Easing valve is installed additional between gas pressure reducing valve and liquid gas storage tank, pressure reducing valve and easing valve are combined into an organism, to liquid when use
Change vapour and carry out decompression guarantee normal pressure supply, turns off liquefied petroleum gas at once with portable drawing valve bonnet when meeting emergency and supply
It gives, when fire behavior occurring around liquid gas storage tank, when environment temperature is increased to 58 DEG C extremely, liquefaction can not turned off voluntarily by external force
Oil gas, it has the triple functions that liquefied gas tank depressurizes, quick closedown and temperature-sensitive are self-closing.
The liquid gas storage tank depressurize easing valve, solve when a fire, because liquefied gas tank leakage caused by burning, explosion
Cause the generation for losing expansion problem.
But liquid gas storage tank depressurizes the case where easing valve still has several drawbacks, leaks for liquid gas storage tank liquefied gas tank
When, it cannot achieve automatic-closing valve, can't resolve because the leakage of liquid gas storage tank liquefied gas tank can produce explosion or generate gassing
Dangerous security hidden trouble.The seal cap of the easing valve of liquid gas storage tank decompression simultaneously connect less reliable, actual use with valve rod
There is the possibility to fall off in the process, causes easing valve work less reliable.

A kind of application method of liquid gas storage tank decompression leakage easing valve, steps are as follows:
It is connect first with hand wheel connecting piece 1-2 with liquid gas storage tank, while ensuring that liquid gas storage tank decompression easing valve is in and opening
Electromagnet 10 is connect by power supply line 10-6 with indoor flammable gas alarm is mounted on, presses valve bonnet 15, seal by state
Cap 3 passes sequentially through hand wheel connecting piece 1-2 air passage, II (1-1- of venthole far from small I 1-1-1 of valve body 1-1 venthole, liquefied gas tank
2), I 1-1-1 of venthole and 1 air passage of valve body export liquefied gas.
When environment temperature rises the temperature for reaching the setting of temperature-sensing element 11, temperature-sensing element 11 extends, and the elastic force of generation will
Valve bonnet 15 and two 16 entirety of magnet rings axially move upwards, and valve bonnet 15 and two magnet rings 16 are during moving upwards, and two
Magnet ring 16 two repulsion upward to magnetic core 5 become the repulsion downward to two magnetic cores 5, small bullet after repulsion balances critical point
Spring 7 discharges, and magnetic core set 6 is forced to axially move downwards, and the seal cap 3 for being mounted on 6 bottom ends of magnetic core set is caused to block small valve body 1-1
I 1-1-1 of venthole, cut off the supply of liquefied gas tank.
When combustion gas leaks, after flammable gas alarm issues the exceeded signal of gas concentration, issued to electromagnet 10
Driving power, electromagnet 10 receive driving power, and enameled wire loop 5 generates magnetic field, generate attraction in static iron core 3 and dynamic iron core 9
Power, because the lower end of electromagnetism push rod 1 is in 8 upper end pit of sealing shroud, sealing shroud 8 is connected with small valve body 1-1, so that dynamic iron core
9 cannot move, until making static iron core 3 axially move upwards with the valve bonnet 15 being connected through a screw thread is whole, until dynamic iron core 9 is bored
The body 10-9-1 conical surface is bonded with the conical surface in the bellmouth 10-3-4 of static iron core 3, and valve bonnet 15 and two magnet rings 16 are being transported upwards
During dynamic, two magnet rings 16 and two repulsion upward to magnetic core 5 become after repulsion balances critical point to two magnetic cores 5
Downward repulsion, little spring 7 discharge, and magnetic core set 6 is forced to axially move downwards, cause to be mounted on the sealing that magnetic core covers 6 bottom ends
Cap 3 blocks I 1-1-1 of venthole of small valve body 1-1, has cut off the supply of liquefied gas tank；
Also it can be used to lift valve bonnet 15 manually and move upwards and there is effect same instead of temperature-sensing element 11.
Temperature-sensing element 11 can be thermometer bulb, memory metal, bimetal leaf or other temperature sensing materials, as long as in temperature
The lower material that deformation occurs of effect can use, and effect is identical.
After the utility model increases electromagnet 10, the flammable gas alarm outside this valve detects that gas concentration is super
After mark, it is powered to the enameled wire loop 10-5 of electromagnet 10, enameled wire loop 10-5 generates magnetic field, in static iron core 10-3 and dynamic iron core
10-9 generates attraction, because the lower end of electromagnetism push rod 10-1 is in 8 upper end pit of sealing shroud.Sealing shroud 8 is connected with small valve body
It connects, prevent dynamic iron core is from moving, until static iron core 10-3 is made to do axial fortune upwards with the valve bonnet 15 being connected through a screw thread is whole
Dynamic, until the dynamic iron core 10-9 conical surface is bonded with the conical surface of static iron core 10-3, valve bonnet 15 and two magnet rings 16 are moving upwards process
In, two magnet ring 16 two repulsion upward to magnetic core 5 become the reprimand downward to two magnetic cores 5 after repulsion balances critical point
Power, little spring 7 discharge, and magnetic core set 6 is forced to axially move downwards, cause the seal cap 3 for being mounted on 6 bottom ends of magnetic core set to block small
I 1-1-1 of venthole of valve body 1-1, has cut off the supply of liquefied gas tank.
Also it can be used to lift valve bonnet 15 manually and move upwards and there is effect same instead of temperature-sensing element 11.
