Description
Technical field
The utility model relates to valve technology field, relates in particular to a kind of by triggering the Decompression valves of realizing pressure release.
Background technique
Decompression valves has another name called safety valve, can automatic on-off according to the working pressure of system, generally be installed on protective system safety on the equipment of locking system or the pipeline.When equipment or manifold pressure surpass the Decompression valves setting pressure, namely automatically open pressure release, guarantee that pressure medium is under setting pressure in the e-quipment and pipe, the protection e-quipment and pipe prevents accident.Existing Decompression valves is generally according to pressure size automatic on-off, it can be accurately and the safety and stability pressure that remains unchanged, in case superpressure, Decompression valves can fully be opened timely pressure release, it can be installed in any position, need not change pressure set points or remove from pipeline just can to keep in repair and check.But on some apparatuses, fork truck for example, the pressure of its pipeline is less for the impact of pipeline, but the pressure of its pipeline affects larger for the oil cylinder that waves that connects fork truck body and crotch, when the pressure of pipeline does not have timely pressure release, easily cause the stroke that waves oil cylinder to surpass spacing and cause its explosion, so need a kind of the utilization wave the Decompression valves that oil cylinder stroke triggers control.
Summary of the invention
Therefore, for above-mentioned problem, the utility model proposes a kind of simple in structure, trigger type Decompression valves that safety coefficient is high, easy to operate, practical.
For achieving the above object, the utility model has adopted following technological scheme: a kind of trigger type Decompression valves, comprise valve body and be located at the interior spool mechanism of valve body, be provided with oil pocket in the described valve body, the two ends, the left and right sides of described valve body are respectively equipped with left valve gap and right valve gap, described right valve gap is provided with filler opening, described valve body is provided with oil outlet, described filler opening is communicated with oil pocket respectively with oil outlet, described spool mechanism comprises thimble, valve pocket, piston sleeve, piston, piston reset spring, described valve pocket is located at described oil outlet position in the oil pocket, described valve pocket offers the valve pocket oil outlet on the side, described valve pocket oil outlet is communicated with the oil outlet of described valve body, described piston sleeve is located at valve pocket near an end of right valve gap, described piston sleeve is provided with piston sleeve filler opening and piston sleeve oil outlet, described piston sleeve oil outlet is communicated with the valve pocket oil outlet, but be jammed on the piston sleeve filler opening to described piston clutch, described piston reset spring is located between piston and the right valve gap, described thimble is located at and is positioned at piston in the oil pocket away from an end of right valve gap, the other end of described thimble passes left valve gap and stretches out outside the valve body, and described thimble is provided with the snap ring that is moved to the left for the restriction thimble.
Further, be provided with the thimble Returnning spring between described snap ring and the piston sleeve.
Further, be positioned on the described thimble with left valve gap cooperation place and be provided with the thimble seal ring.
Further, be positioned on the described left valve gap with the valve body cooperation place and be provided with left valve bonnet seal circle.
Further, described valve body is provided with for convenient fixing fixed plate, and described fixed plate is provided with the bar shaped fixed hole.
By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: compare with existing Decompression valves, thereby this Decompression valves plays the folding of piston and piston sleeve by the thimble pushing piston, thereby so that the pipeline connection that filler opening is connected with oil outlet or closure, reach the effect of pressure release, having played can be according to Stroke Control pressure release, safer convenience, the effect that is easier to operate.
