Description
Technical field
The present invention relates to fluid valve field, in particular to a kind of gas valve of pressure-adjustable.
Background technology
The gas that generally we are used to burn has liquefied petroleum gas, a natural gas, different combustion gas have different calorific values and
With different pressure, the pressure greatly 2800p of usual liquefied gas, and it is 2000P that the pressure of natural gas is smaller, therefore two kinds
The gas valve specification that combustion gas matches is also different.In daily life, when the one of which of liquefied petroleum gas or natural gas is finished
Or when stopping supplying, people, which need to change, uses another be used as to replace, and now needs to also need to change outside replacing tracheae
Gas valve, Renewal process is complicated, is made troubles for life.
The content of the invention
It is contemplated that at least solves one of above-mentioned technical problem in correlation technique to a certain extent.Therefore, this hair
Bright to propose a kind of gas valve of pressure-adjustable, there are two kinds of gas pressure patterns to be selected for user for it.
To achieve the above object, technical scheme is as follows：
A kind of gas valve, including valve body and housing, valve body form valve pocket with housing, inlet chamber and outlet chamber are provided with valve body,
Fa Mo mechanisms are installed, valve pocket is divided into counter balance pocket, and the relief chamber communicated with outlet chamber, relief chamber by Fa Mo mechanisms in valve body
Connected between inlet chamber by spool bore, Fa Mo mechanisms are provided through spool bore and extended to inside inlet chamber, for opening
The valve element of the spool bore is closed, housing includes the upper casing being arranged on valve body, and the regulating nut being threadedly coupled with upper casing, put down
Weighing apparatus chamber is internally provided with the big spring for acting on upper casing cavity wall, and may act on the little spring of regulating nut, regulating nut
One end is the cavity for little spring of stepping down, and the other end is provided with can be with the retaining wall of little spring phase separation.The first gas pressure pattern
When, the retaining wall of regulating nut is located at the outside of upper casing, and little spring can not act on regulating nut, when low voltage value combustion gas enters air inlet
Enter relief chamber by spool bore after chamber to flow out from outlet chamber again, gaseous-pressure, which acts on Fa Mo mechanisms, under this pattern makes its stress
Rise and compress big spring, outlet pressure is equal to the pressure that admission pressure subtracts big spring, reaches the effect of low voltage value gas pressure-reducing
Fruit；During second of gas pressure pattern, anti-dress makes retaining wall be located inside upper casing to regulating nut, and now little spring may act on regulation spiral shell
Cap, relief chamber is entered again from gas pressure under outlet chamber outflow, this pattern by spool bore after high-voltage value combustion gas enters inlet chamber
Power, which acts on Fa Mo mechanisms, to be risen its stress and compresses big spring and little spring, and outlet pressure subtracts size equal to admission pressure
The gross pressure of spring, reach the effect of high-voltage value gas pressure-reducing.When admission pressure is unstable excessive, Fa Mo mechanisms are by larger
Pressure make to move on at spool bore on valve element, now reduced into the throughput of relief chamber, the air pressure inside relief chamber accordingly drops
Low, Fa Mo mechanisms move in the presence of by large and small spring, and valve element follows Fa Mo mechanisms to move down, and corresponding increase enters relief chamber
Throughput, the effect of this process are to automatically adjust the air pressure in relief chamber, make the outlet air pressure of outlet chamber steady.
As the improvement of above-mentioned technical proposal, Fa Mo mechanisms include the glue that peripheral sealing is fixed between upper casing and valve body
Film, and the valve core plate inside glued membrane is nested in, one end of valve element is fixed on valve core plate, and one end of little spring is socketed in valve element
Fixing end on, the other end is extended at regulating nut.
As the improvement of above-mentioned technical proposal, valve core plate is provided with big spring installation portion, and one end of big spring is socketed in greatly
Spring mountings, the other end are connected to shell wall chamber.
As the improvement of above-mentioned technical proposal, the retaining wall of regulating nut sets outwardly convex boss.In second of pattern
Lower convex platform can limit little spring and be displaced to other positions.
As the improvement of above-mentioned technical proposal, the retaining wall of regulating nut is provided with air-vent.Air-vent can Shi Fa films mechanism
During rising, cavity and extraneous pressure between balanced valve film mechanism and upper casing.
As the improvement of above-mentioned technical proposal, housing is provided with the protection cap for entangling regulating nut.
Present invention additionally comprises the second outlet chamber being connected with outlet chamber, the second outlet chamber is internally provided with for completely cutting off the
The seal of two outlet chambers and ft connection, and the motion stops for being used to block the second outlet chamber being socketed in seal.
As the improvement of above-mentioned technical proposal, motion stops are set between one end in the second outlet chamber and seal
There is relief spring.
As the improvement of above-mentioned technical proposal, the exposed one end of seal is provided with insurance support, insures and is set on support
There is neck, the exposed junction of motion stops is provided with the kelly being engaged with neck.When user make kelly depart from neck limitation,
In the presence of relief spring, motion stops clog the outlet of the second outlet chamber, reach the effect for closing the second outlet chamber.
As the improvement of above-mentioned technical proposal, valve body is provided with the passage that the second outlet chamber connects with relief chamber.
The beneficial effects of the invention are as follows：The gas valve of the present invention is made up of valve body and housing, and valve body forms valve pocket with housing,
Be internally provided with Fa Mo mechanisms, and be respectively acting in Fa Mo mechanisms the big spring of upper casing and regulating nut and small
Spring, regulating nut are arranged to the male connector of one end closure, and little spring does not work during the first pattern, and combustion gas enters
Enter relief chamber by spool bore after inlet chamber to flow out from outlet chamber again, gaseous-pressure, which acts on Fa Mo mechanisms, under this pattern makes it
Stress rises and compresses big spring, and outlet pressure is equal to the pressure that admission pressure subtracts big spring, reaches low voltage value gas pressure-reducing
Effect, during second of pattern, anti-dress makes retaining wall be located inside upper casing to regulating nut, and now little spring may act on regulation spiral shell
Cap, relief chamber is entered again from gas pressure under outlet chamber outflow, this pattern by spool bore after high-voltage value combustion gas enters inlet chamber
Power, which acts on Fa Mo mechanisms, to be risen its stress and compresses big spring and little spring, and outlet pressure subtracts size equal to admission pressure
The gross pressure of spring, reach the effect of high-voltage value gas pressure-reducing.User can be by adjusting the mounting means of regulating nut, selection
Two kinds of gas pressure patterns use, and avoid because needing replacing gas families and the complex process of dismounting and change gas valve, convenient use.
Secondly the motion stops with relief spring are set in the second outlet chamber and limit the insurance support of motion stops displacement, the
When two outlet chambers are of little use, the construction of switch closed at any time is provided for user, to provide insurance safely with gas, use range is wide
It is general.
