Summary of the invention
The purpose of this utility model is to provide automobile-used gas tank two stage pressure reducing device, is transported out by the rock gas in gas tank or gas cylinder by this device, used for user, for gas combustion automobile user increases a function.
The utility model is achieved in that automobile-used gas tank two stage pressure reducing device comprises one-level pressure relief valve, one-level pressure relief valve is identical with second depressurized valve arrangement, one-level pressure relief valve and second depressurized valve are cascaded, the suction port of one-level pressure relief valve is connected with the gas port that adds of gas tank by import pipe nipple, and the air outlet of second depressurized valve is connected by flexible pipe with gas equipment by outlet pipe nipple.
The beneficial effects of the utility model are: this device achieves the outer defeated utilization of natural gas used for automobile.The utility model has two stage pressure reducing function, and outer defeated rock gas is transferred out through the decompression of two reduction valve again.In order to ensure safe and reliable, simultaneously also in order to observe conveniently, the utility model has also installed low-pressure meter and high pressure gauge in one-level pressure relief valve.While guarantee safety, also provide conveniently for user grasps air pressure situation at any time.The utility model structure is simple, when not changing original gas tank or gas cylinder adds port configurations, making gas combustion automobile provide trip for user efficiently simultaneously, for user brings more function and convenience, having good using effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model one-level pressure relief valve.
Fig. 3 is the drawing in side sectional elevation of the utility model one-level pressure relief valve.
Embodiment
Below in conjunction with accompanying drawing in detail the utility model is described in detail, and unrestricted protection domain of the present utility model.See Fig. 1 and Fig. 2, automobile-used gas tank two stage pressure reducing device, comprises one-level pressure relief valve.One-level pressure relief valve is provided with surge-chamber 3, low pressure chamber 4 and hyperbaric chamber 7, and in surge-chamber 3, be provided with pressure regulation bar 1 and pressure adjusting spring 2, pressure adjusting spring 2 is arranged between pressure regulation bar 1 and spring seat 8.Spring seat 8 penetrates surge-chamber 3 and is fixed together with pressure adjusting spring 2 from the upper cover plate of low pressure chamber 4.Shutter spring and live cover push-rod 6 are housed in hyperbaric chamber 7, and shutter spring is arranged on the below of live cover push-rod 6, and the top body of rod of live cover push-rod 6 passes and contacts with pressure adjusting spring 2 from the upper chamber in hyperbaric chamber 7.Its air inflow regulates by pressure regulation bar 1, pressure adjusting spring 2, spring seat 8 and live cover push-rod 6.One-level pressure relief valve is identical with second depressurized valve arrangement, one-level pressure relief valve and second depressurized valve are cascaded, the suction port of one-level pressure relief valve is connected with the gas port that adds of gas tank by import pipe nipple 5, and the air outlet of second depressurized valve is connected by flexible pipe with gas equipment by outlet pipe nipple 9.The cavity of the low pressure chamber 4 of one-level pressure relief valve is provided with low-pressure meter interface and is connected with low-pressure meter; The cavity in the hyperbaric chamber 7 of one-level pressure relief valve is provided with high pressure gauge interface and is connected with high pressure gauge.Import pipe nipple 5 one end is provided with connecting thread and is connected with hyperbaric chamber 7, and the other end installs plug, and the body at connecting thread rear portion is provided with limit dais and inlet hole.The body of import pipe nipple 5 can insert automobile-used gas tank or gas cylinder adds in gas port, and the both sides of the enterprising pore of body are provided with seal ring, is sealed in the two ends that gas tank or gas cylinder add gas port.The natural gas via air inlet pipe nipple 5 exported from natural gas tank or gas cylinder enters hyperbaric chamber 7, its air inflow can observed by high pressure gauge, the rock gas being entered low pressure chamber 4 by the valve in hyperbaric chamber 7 can observed by low-pressure meter, and user regulates by the pressure regulation bar 1 of one-level pressure relief valve.The rock gas entering second depressurized valve also can regulate by the pressure regulation bar of second depressurized valve.If do not install high pressure gauge and low-pressure meter, user then will reduce the open amount of two reduction valve pressure regulation bars 1 as far as possible, to ensure safety.The cavity of the low pressure chamber 4 of one-level pressure relief valve is also provided with pressure relief opening 10, in this pressure relief opening 10, plug is housed.When entering the gas in low pressure chamber 4 and being too much, open this pressure relief opening 10, gas is bled off, too much gas can certainly be bled off by the connecting hose of kitchen range.
Below for gas range, using method and the notice of this device are described:
1, should determine that this device stands intact before using, and check that whether the seal ring of import pipe nipple 5 air inlet position is intact, have free from dust and dirt, and remove in time.
What 2, import pipe nipple 5 is installed to automobile-used gas tank air entraining valve adds gas port place, is connected by outlet pipe nipple 9, tighten the plug of import pipe nipple 5 body rear end and the clamping nut of gas range connecting hose with the connecting hose of gas range.
3, before opening the air entraining valve of automobile-used gas tank, the pressure regulation bar 1 of one-level pressure relief valve should first be closed.
To side be stood in when 4, opening this device, and observe the pressure in gas tank by the high pressure gauge on one-level pressure relief valve.
5, slowly should rotate the pressure regulation bar 1 of one-level pressure relief valve, make it open, be adjusted to working pressure 0.5 MPa of low-pressure meter instruction.If the gas entered in one-level pressure relief valve is too many, after the air entraining valve of automobile-used gas tank should be closed, is released in this device by pressure relief opening 10 and readjust after a part of gas.
6, user regulates the pressure regulation bar of second depressurized valve from childhood and greatly by gas consumption, to avoid accident.
7, after use terminates, first close the air entraining valve of automobile-used gas tank, then open the connecting hose on gas range or by pressure relief opening 10, the gas in this device all got rid of.
8, properly should preserve this device, avoid clashing into vibrations, do not leave place that the is outdoor or medium that is corrosive in.
