Abstract
The utility model relates to the technical field of valves, a relief pressure valve structure is disclosed, its characterized in that: the improved steel cylinder valve comprises a valve body, the one end of valve body is the air inlet, be equipped with the connecting rod that is used for connecting the steel bottle on the air inlet, the connecting rod is the toper, just the connecting rod is kept away from the one end of valve body is the arc, O type sealing washer has been cup jointed in the outside of connecting rod. The utility model provides a pressure reducing valve structure cup joints O type sealing washer through the outside at the connecting rod, because the effect of O type sealing washer after the connecting rod of pressure reducing valve is connected with the steel bottle, has avoided leaking. The utility model discloses simple structure, excellent in use effect easily uses widely.
Description
Technical Field
The utility model relates to the technical field of valves, especially, relate to a relief pressure valve structure.
Background
The existing high-pressure reducing valve is connected with a steel cylinder through a metal conical head connecting rod with a radian, the advantage of the connection is that the high pressure can be borne, but the defect is obvious, and the problem of leakage can often occur even after the connecting rod of the reducing valve is screwed by a wrench (rotated to be fixed) when being connected with the steel cylinder.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a relief pressure valve structure avoids producing the leakage after being connected with the steel bottle.
The utility model provides a technical scheme that its technical problem adopted is:
the utility model provides a relief pressure valve structure, includes the valve body, the one end of valve body is the air inlet, be equipped with the connecting rod that is used for connecting the steel bottle on the air inlet, the connecting rod is the toper, just the connecting rod is kept away from the one end of valve body is the arc, O type sealing washer has been cup jointed in the outside of connecting rod.
Preferably, the connecting rod is provided with a mounting groove, and the O-shaped sealing ring is mounted in the mounting groove.
Preferably, the depth of the mounting groove is 60% -80% of the cross-sectional diameter of the O-shaped sealing ring.
Preferably, the connecting rod is provided with two O-shaped sealing rings which are arranged at intervals.
Preferably, the distance between the two O-shaped sealing rings is 5-10 mm.
The embodiment of the utility model provides a relief pressure valve structure compares with prior art, and its beneficial effect lies in: through cup jointing O type sealing washer in the outside of connecting rod, because the effect of O type sealing washer has avoided leaking after the connecting rod of relief pressure valve is connected with the steel bottle. The utility model discloses simple structure, excellent in use effect easily uses widely.
Drawings
Fig. 1 is a schematic structural diagram of the pressure reducing valve of the present invention.
Wherein: 1-valve body, 2-connecting rod, 3-O type sealing ring, 4-mounting groove.
Detailed Description
The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.
As shown in fig. 1, the utility model provides a preferred embodiment's a relief pressure valve structure, including valve body 1, valve body 1's one end is the air inlet, be equipped with the connecting rod 2 that is used for connecting the steel bottle on the air inlet, connecting rod 2 is the toper, just connecting rod 2 keeps away from the one end of valve body is the arc, O type sealing washer 3 has been cup jointed in the outside of connecting rod 2.
According to the pressure reducing valve structure based on the technical characteristics, the O-shaped sealing ring 3 is sleeved on the outer side of the connecting rod 2, and leakage is avoided due to the action of the O-shaped sealing ring 3 after the connecting rod 2 of the pressure reducing valve is connected with a steel cylinder. The utility model discloses simple structure, excellent in use effect easily uses widely.
In this embodiment, for convenience, the O-ring 3 is installed, the connecting rod 2 is provided with an installation groove 4, the O-ring 3 is installed in the installation groove 4, and the depth of the installation groove 4 is 60% -80% of the diameter of the cross section of the O-ring 3.
In this embodiment, in order to further ensure the sealing effect, the connecting rod 2 is provided with two O-shaped sealing rings 3, the two O-shaped sealing rings 3 are arranged at intervals, and the interval between the two O-shaped sealing rings 3 is 5 to 10 mm.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and replacements can be made without departing from the technical principle of the present invention, and these modifications and replacements should also be regarded as the protection scope of the present invention.
