Abstract
Disclosed is an energy-saving pressure-reducing valve for a liquefied petroleum gas steel cylinder, comprising a gas inlet pipe, a pressure-reducing chamber, a pressure-reducing mechanism and a gas outlet pipe. The utility model is provided with a passage between the gas inlet pipe and the gas outlet pipe, and the passage is provided with a control valve. The new pressure-reducing valve can also provide the petroleum gas passing through the passage and getting into a stove for burning when the liquefied petroleum gas pressure in the steel cylinder is low; thus the service time of the petroleum gas in the steel cylinder is prolonged and the energy can be saved, which can bring direct benefit to the users.
Description
The utility model belongs to a kind of gas decompression apparatus.
The existing reduction valve that is used for liquefied petroleum ga steel cylinder can reduce the pressure of petroleum gas in the steel cylinder, makes the pressure of the petroleum gas that comes out from reduction valve drop to the degree that is suitable for entering the kitchen range burning.But there is such defective in this reduction valve: after liquefied petroleum gas (LPG) has been used a period of time in the steel cylinder, the pressure of residual petroleum gas reduces in the bottle, can not start the mechanism of decompressor in the reduction valve, petroleum gas also just can not gush out by reduction valve, raffinate gasification in the steel cylinder is also unrenewable, cause waste, also bring economic loss to the user.
The purpose of this utility model provides a kind of new reduction valve, when the liquefied petroleum atmospheric pressure in the steel cylinder is higher, can guarantee safety, gas just commonly used, in the time of can not spraying by reduction valve when the reduction of petroleum gas pressure, can make petroleum gas behind the straight-through steam outlet pipe of the suction tude of reduction valve, enter the kitchen range burning again without the relief chamber of reduction valve, make residual petroleum be so incensed that to make full use of, energy saving is also brought material benefit to the user.
Scheme of the present utility model is to improve the structure of existing liquefied petroleum ga steel cylinder with reduction valve, comprise original suction tude (1), relief chamber (2), the mechanism of decompressor (3), steam outlet pipe (4), the improvement of being done is that a passage (5) that directly is communicated with suction tude (1) and steam outlet pipe (4) is set in reduction valve in addition, and a control valve (6) is set on passage (5).
When the utility model uses, in steel cylinder under the liquefied petroleum atmospheric pressure condition with higher, control valve (6) is closed, and high pressure petroleum gas arrives kitchen range burning by steam outlet pipe (4) ejection from suction tude (1) after via hole (8) enters relief chamber (2) step-down again; When petroleum gas pressure reduces, in the time of can not passing through relief chamber (2) ejection, just open control valve (6), make low pressure petroleum gas directly enter steam outlet pipe (4) ejection and arrive the kitchen range burning through passage (5).
In order to prevent that control valve (6) mistake is opened when steel cylinder PetroChina Company Limited. atmospheric pressure is higher, can a self-locking device (7) to be set to control valve (6), only when needs are opened control valve (6), just can open it by manual operation.
The utility model has been done improvement to the existing reduction valve that is used for liquefied petroleum ga steel cylinder, can make the liquefied petroleum gas (LPG) in the steel cylinder use more to the greatest extent, calculate by being filled with 15 kilograms of liquefied petroleum gas (LPG) in the steel cylinder, use the utility model to compare with existing reduction valve, can prolong the usefulness gas time more than 10 hours, energy-saving effect is comparatively obvious, is subjected to the user and welcomes.
Fig. 1 is a structural representation of the present utility model.
1 is suction tude among the figure, and 2 is relief chamber, and 3 is the mechanism of decompressor, 4 is steam outlet pipe, and 5 for connecting the passage of suction tude (1) and steam outlet pipe (4), and 6 is the control valve on the passage (5), 7 is the self-locking device of control valve (6), and 8 is the hole that suction tude (1) is led to relief chamber (2).
When making, the utility model only needs existing reduction valve is made improvements slightly, between suction tude (1) and steam outlet pipe (4), open a passage (5) in addition, a control valve (6) is set on passage (5), again control valve (6) being installed additional a self-locking device (7) can finish, and makes very convenient.
Claims (2)
1, a kind of reduction valve that is used for liquefied petroleum ga steel cylinder comprises suction tude, relief chamber, the mechanism of decompressor, steam outlet pipe, it is characterized in that being provided with in addition in reduction valve a passage that directly is communicated with suction tude and steam outlet pipe, and a control valve is set on passage.
2, by the described reduction valve of claim 1, it is characterized in that being provided with on the control valve self-locking device.
