Abstract
The utility model relates to a safety pressure-reducing valve. A pressure-reducing valve and a safe device are arranged in a valve body; a release button corresponding to the safe device is arranged on the valve body. The utility model is especially suitable for matching with a gas range. When a gas supply pipeline breaks or the gas range is accidentally extinguished, the safe device can automatically block a gas source; the leakage of gas can be prevented; thereby, the utility model has the advantage of safety.
Description
The utility model is a kind of reduction valve, is particularly suitable for and the supporting use of gas range.
Existing and the matching used reduction valve of gas range only have the function of regulating air pressure, in use, if kitchen range accident extinguishing or gas piping cracking, can not close source of the gas automatically, not only cause the waste of the energy, even serious accident such as also can set off an explosion, catch fire.
The purpose of this utility model is a kind of reduction valve safe in utilization of design.
The utility model comprises valve body, is provided with gas-entered passageway and decompressor in it, it is characterized in that being provided with safety installations in the valve body of inlet end; Be equipped with on the valve body and the corresponding release button of safety installations.
The utility model is provided with safety installations, gas cooker accident extinguishing during as if gas piping cracking or use, but its safety installations self-blocking source of the gas does not cause gas leak, and safe and reliable.
Fig. 1 is embodiment's a structural representation;
Fig. 2 is the structural representation of release button.
The accompanying drawing illustrated embodiment comprises the valve body that is made of upper shell 3 and lower shell body 10, is provided with taper gas-entered passageway 23 in the valve body.In valve pocket 25, be provided with decompressor, this decompressor comprises diaphragm 9, packing ring 8 and axis 7, be connected with spring clip 5 on the axis 7, be connected with spring 6 between spring clip 5 and the packing ring 8, be connected with between packing ring 8 and the valve body and adjust spring 4, the lower end of axis 7 is connected with the lever 11 that is supported by lever shaft 12, and an end of lever 11 is connected with the sealing gasket 13 that can block source of the gas.In the valve body of inlet end, be provided with safety installations, this safety installations comprises the cavity 2 that communicates with gas-entered passageway 23, operation ball 22 is installed in it, and the bottom of cavity 2 is provided with and operation ball 22 corresponding grooves, is connected with seal ring 14 on the suction port 16 between cavity 2 and the gas-entered passageway 23.Release button is installed on the valve body, and the position of this release button is corresponding with safety installations.Said release button comprises outer seat 21, and axle sleeve 24 is installed in it, axle 19 in being equipped with in the axle sleeve 24, and the upper end of axle sleeve 24 and interior axle 19 is connected with knob 18, is connected with return spring 20 between knob 18 and the outer seat 21.Be connected with damping rubber circle 17 between outer seat 21 and the axle sleeve 24.
During use, gas range is linked to each other with joint 1.After opening gas source switch, air-flow enters cavity 2 from sleeve 15, promotes operation ball 22 and moves, and suction port 16 is blocked; Press release button, interior axle 19 moves down to be pushed operation ball 22 open from gas import 16, make air-flow enter valve pocket 25.After knob resets, the gas cooker proper functioning.When occur that gas piping breaks or gas cooker accident extinguishing phenomenon after, throughput changes, work ball 22 promptly can move obstruction suction port 16 immediately, thereby air-flow is cut off.
