Description
Technical field
The utility model relates to the decompressor that a kind of solenoid valve and reduction valve link together.
Background technique
At present, the decompressor kind on market is a lot, and its profile and structure are different.With the immediate a kind of decompressor of the utility model; Include solenoid valve and reduction valve, said reduction valve includes one-level decompressor and second depressurized device, is provided with passage between described one-level decompressor and the second depressurized device; Be provided with flow regulator in the said passage; The diaphragm support interlock of the adjustable lever of said flow regulator and second depressurized device, said valve body is provided with the diaphragm support regulation structure of second depressurized device, and the diaphragm support controlling mechanism of the second depressurized device of the decompressor of this structure is very complicated; The instrument that needs specialty, very inconvenient.
Summary of the invention
The utility model has overcome the deficiency of existing technology, provides a kind of simple in structure, novel decompressor easy to adjust.
Realize above-mentioned purpose, the utility model adopts following technological scheme: a kind of decompressor includes solenoid valve and reduction valve; Said reduction valve includes one-level decompressor and second depressurized device; Be provided with passage between described one-level decompressor and the second depressurized device, be provided with flow regulator in the said passage, the diaphragm support interlock of the adjustable lever of said flow regulator and second depressurized device; It is characterized in that: said relief valve body is provided with the controlling device of the spring pressure of regulating the second depressurized device; This controlling device includes screw rod and spring seat, and spring one end of second depressurized device is conflicted on the diaphragm support of second depressurized device, and the other end is conflicted on spring seat; Said spring seat and screw flight spin; Between spring seat and the relief valve body guide mechanism is set, screw rod and relief valve body are rotatably assorted, and said screw rod is positioned on the outer end of relief valve body and is set with the turncap that can supply hand directly to rotate.
Through adopting such scheme; We only need just can realize the adjusting of second depressurized device internal pressure size with the direct rotation adjusting turncap of hand; Also drive simultaneously the adjusting of the flow size of flow regulator in the passage between one-level decompressor and the second depressurized device in addition, very convenient.
