Abstract
The utility model relates to a gas decompression valve for the reduction of the gas pressure in the gas tank. The valve comprises a valve intake port (1) communicated with an intake inlet port (3) of the reducer chamber (2) through the gas channel. The thimble valve of the intake inlet (3) is propped against by a face of the decompression diaphragm piece (5). The other face of the decompression diaphragm piece (5) is propped against by the spring (7) fixed on the cover body of the decompression chamber (2). The outlet port (8) of the decompression chamber (2) is communicated with the outlet port (9) of the valve by the gas channel. The decompression valve is characterized in that a circular decompression diaphragm (10) centre opening on the decompression diaphragm piece (5) is sheathed by a center convex platform (12) of a circular metal tip piece (11). The decompression diaphragm piece (5) is in a high and low two circular-shaped plane and becomes a groove mode between the two planes.
Description
Technical field:
The utility model relates to a kind of combustion gas reduction valve that is used for pressure gas jar combustion gas decompression.
Background technique:
Combustion gas reduction valve in the past, because it is the decompression of the elasticity in its underpressure chamber film is plane, therefore, relatively poor to the voltage regulation result of pressure gas.
Technology contents:
In order to improve the voltage regulation result of combustion gas reduction valve, the utility model provides: a kind of novel gas reduction valve, it comprises, the suction port of valve (1) is communicated with the suction port (3) of underpressure chamber (2) through air flue, the thimble valve (4) of suction port (3) is depressurized a roof pressure of film spare (5), the another side of decompression film spare (5) is by spring (7) roof pressure of being located by the lid (6) of underpressure chamber (2), the air outlet (8) of underpressure chamber (2) is communicated with air outlet (9) with valve through air flue, it is characterized in that: the central opening of the annular decompression film (10) of decompression film spare (5) is by platform (12) suit of garden shape metal head part (11) central protrusion, it is high that decompression film spare (5) is, low two-stage plane is the groove shape between two planes.The ring plain inner edge of decompression film (10) and the outer wing of garden shape metal head part (11) amplexiform, and the central opening of platform (12) the suit annular decompression film (10) of head part (11) like this, is stablized both and connected as one; Lid (6) spinning is installed, and on the one hand, lid (6) outer rim is with the ring plain outer rim compressing location of annular decompression film (10); On the other hand, make the one side of the platform (12) of spring (7) roof pressure garden shape metal head part (11) central protrusion, its another side makes it shrink back thimble valve (4) roof pressure, and valve (4) is opened.During valve work, at first the suction port (1) of pressure gas jar and valve is connected; Pressed gas enters, and enters underpressure chamber (2) through air flue,
Connect a valve control channel (13) on the air flue in the valve body afterwards of underpressure chamber (2), the valve plug that is taper (14) that can move towards back and forth movement along passage (13) is arranged in the control channel (13), the postbrachium of valve plug (14) is set with elastic seal ring (16).Post-decompression combustion gas can be controlled by valve plug (14) before going out air outlet (9); The postbrachium of control valve plug (14) makes the valve plug (14) of taper stop up poroid conduit wall, can cut off gas circuit, and the postbrachium of control valve plug (14) makes the valve plug (14) of taper leave poroid passage, and gas circuit is connected.The conical surface gradient that valve plug (14) is taper one end is 25-30 when spending, and is excellent to the sealing effect of poroid conduit wall; The effect of elastic seal ring (16) is closed channel (13), makes combustion gas can not leak from passage (13).
Suction port (1) is opened in the metal interface face that valve is connected with gas cylinder, then when docking with gas can, can not damage the gas can interface because suction port (1) does not expose; It is that middle mind-set both wings wire is extended shape that suction port (1) is with hole, central garden, and when docking with the pressure gas jar, during the hole, central garden of the centre lathe type valve roof pressure of pressure gas jar, sealing suction port (1), gas can enter smoothly from the wire elongated hole of both wings.

Embodiment:
See Fig. 1, the suction port of valve (1) is communicated with the suction port (3) of underpressure chamber (2) through air flue, the thimble valve (4) of suction port (3) is depressurized a roof pressure of film spare (5), the another side of decompression film spare (5) is by spring (7) roof pressure of being located by the lid (6) of underpressure chamber (2), the air outlet (8) of underpressure chamber (2) is communicated with the air outlet (9) of valve through air flue, see Fig. 2, garden shape metal head part (11) is divided into, following two, from last, lower direction clamps annular decompression film (10), the central opening of the annular decompression film (10) of decompression film spare (5) is by platform (12) suit of garden shape metal head part (11) central protrusion, it is high that decompression film spare (5) is, low two ring plains are the groove shape between two planes.See Fig. 5, thimble valve (4) is by under the roof pressure, and gas enters from arrow (19) direction of valve (17), comes out from arrow (20) direction of valve (17).Spring (18) pressurized, valve (17) is opened; On the contrary, then close.
See Fig. 3, zigzag air flue in the valve body afterwards of underpressure chamber (2) is from central cutout, connect valve control channel (13), the valve plug that is taper (14) that can move towards back and forth movement along passage (13) is arranged in the control channel (13), the postbrachium of valve plug (14) is set with elastic seal ring (16).The conical surface gradient that valve plug (14) is taper one end is that 25 degree are better to the air flue sealing.
See Fig. 4, suction port (1) is opened in the metal interface face that valve is connected with gas cylinder, and being with hole, central garden is that middle mind-set both wings wire is extended shape.
