Description
Technical field
The field of the invention is related to a kind of double-stage air energy-saving valve.
Background technology
Gas pressure reducer is a kind of outlet pressure that inlet pressure is reduced to a certain needs by regulation, and relies on gas sheet
The energy of body, makes outlet pressure keep automatically stable valve.Gas pressure reducer will realize the decompression to gas, gas pressure reducer
In need to arrange supplied gas and reduce pressure cavity, a decompression cavity can be only done a gas decompression process.Existing gas
Pressure-reducing valve is provided only with a supplied gas decompression cavity, it is meant that the gases at high pressure that existing gas pressure reducer is entered to air inlet are only
Can be through once reducing pressure, i.e., the gases at high pressure for entering from the air inlet of gas pressure reducer are reduced pressure in decompression cavity only once
Afterwards, outlet output then directly from gas pressure reducer.Its exist deficiency be:It is low that outlet on gas pressure reducer is exported
Pressure gas momentum is excessive and flow velocity is too fast, causes the gas flow in the unit interval excessive, causes the waste of gas.
If running into if secondary pressure will being carried out to gases at high pressure, generally require two gas pressure reducers of concatenation, ability
Realization carries out secondary pressure to gases at high pressure, the decompression as disclosed by Authorization Notice No. is CN203847998U patent documents
Valve, but so one, situations such as easily the junction between two pressure-reducing valves leaks air, the waste of gas is caused,
Generation potential safety hazard, is that gas completes to reduce pressure twice and needs to use two gas pressure reducers more in addition, realizes gas decompression institute
What is needed is relatively costly.
The content of the invention
The technical problem to be solved is to provide and a kind of completes to subtract the secondary of gas in same pressure-reducing valve
Pressure so that the low-pressure gas impulse force of output is little and the little double-stage air energy-saving valve of flow velocity.
To solve above-mentioned technical problem, the technical scheme that the present invention is provided is：A kind of double-stage air energy-saving valve, it includes subtracting
Valve body, offers primary air inlet and main gas outlet on the decompression valve body；The decompression valve body is provided with for examining
The pressure gauge of the primary air inlet air pressure of decompression valve body is surveyed, the valve body that reduces pressure is respectively arranged on the left side and the right side gases at high pressure air inlet pipe
With low-pressure gas escaping pipe I；The first airtight cavity of supplied gas decompression is offered on one end of the decompression valve body, it is described
The first airtight cavity air inlet and the first airtight cavity gas outlet are offered on first airtight cavity, first airtight cavity enters
Gas port is connected with primary air inlet, and valve element I, and the venthole of valve element I and the first closed chamber are provided with the first described airtight cavity
Body gas outlet connects；It is described decompression valve body the other end on offer supplied gas decompression the second airtight cavity, described second
Airtight cavity is provided with the second airtight cavity air inlet and the second airtight cavity gas outlet, the first airtight cavity gas outlet with
Second airtight cavity air inlet is connected, and is provided with valve element II, and the venthole of valve element II is close with second in second airtight cavity
Closed chamber body gas outlet connects, and the second airtight cavity gas outlet is connected with main gas outlet.
After above structure, the present invention compared with prior art, with advantages below：By the two ends of the valve body that reduces pressure
First airtight cavity and the second airtight cavity of supplied gas decompression are opened up respectively, by being provided in the first airtight cavity to the
Gases at high pressure are implemented to reduce pressure for the first time, secondly by setting valve by the valve element I of the gas enforcement decompression of one airtight cavity air inlet
The venthole of core I, the first airtight cavity gas outlet are connected with the second airtight cavity air inlet three so that complete decompression for the first time
Gas be discharged in the second airtight cavity, arrange in the second airtight cavity for entering to the second airtight cavity air inlet
Gas implements the valve element II of decompression, and gas is implemented once to reduce pressure again, then closed with second by arranging the venthole of valve element II
Cavity gas outlet connects, and the second airtight cavity gas outlet is connected with the main gas outlet of decompression valve body, is finally realized from pressure-reducing valve
Main gas outlet of the gases at high pressure that the primary air inlet of main body is entered from decompression valve body after secondary pressure is discharged, and finally exists
The purpose of secondary pressure is achieved that in one pressure-reducing valve, it is ensured that the low-pressure gas impulse force of output is little little with flow velocity, more efficient,
Gas is fully utilized, reduces the waste of gas, while the safety that turn avoid in background technology caused by two valve concatenations is hidden
Suffer from gas, the cost completed required for gas second depressurized is relatively low.
