Abstract
The utility model discloses a piston type pressure regulator which comprises a valve body, an air inlet channel and an air outlet channel. A valve cavity is formed in the valve body. The air inlet channel and the air outlet channel are connected with the valve cavity. A valve core is arranged in the air inlet channel. One side of the valve core is provided with an ejector rod extending into the valve cavity. The ejector rod is provided with a pressing cap. The valve body is further provided with an elastic part abutting against the pressing cap, a top cover and a pressure adjusting nut, wherein the top cover and the pressure adjusting nut are matched with the elastic part. The piston type pressure regulator is simple in structure, easy and convenient to assemble, wide in pressure adjusting range, high in corrosion resistance and long in service life.
Description
[technical field]
The utility model relates to a kind of piston type pressure governor.
[background technique]
At present, existing pressure governor particularly direct acting type adopts spring action principle to carry out pressure regulation mostly, but range of regulation is narrower, pressure reduction is less, and the scope of pressure regulation cannot regulate, complex structure, expensive, simultaneously because of ultrahigh pressure erosion, cavitation that particularly super large pressure reduction produces, add other chemical corrosion, make the component such as pressure governor valve port fragile, the life-span is on the low side.
[model utility content]
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of simple in structure, range of regulation is wide, corrosion resistance is strong, the life-span is long piston type pressure governor is provided.
The purpose of this utility model is achieved in that
A kind of piston type pressure governor, is characterized in that it comprises valve body, and described valve body is provided with valve pocket, and the gas-entered passageway and the outlet passageway that are connected with valve pocket; In described gas-entered passageway, be provided with valve inside, a side of described valve inside is provided with the push rod extending in valve pocket, and described push rod is provided with pressure cap, and described valve body is also provided with the elastic component offseting with pressure cap, and the top cover and the look nut that coordinate with elastic component.
A kind of piston type pressure governor as above, it is characterized in that described valve body comprises a screw rod, described gas-entered passageway is arranged in screw rod, and one end cover of described screw rod has valve pocket, the other end of valve pocket is connected with upper cover, and described look nut is movably connected in and covers.
A kind of piston type pressure governor as above, is characterized in that described elastic component is a spring.
A kind of piston type pressure governor as above, it is characterized in that described valve inside comprises the valve core print seat being fixedly connected with gas-entered passageway, push rod is movably arranged in valve core print seat, and in valve core print seat, on push rod, cover has Returnning spring, is provided with valve inside passage between valve core print seat and push rod.
The utility model is simple in structure, it is simple and convenient to assemble, and range of regulation is wide, corrosion resistance is strong, the life-span is long.
