Abstract
The utility model relates to a stop valve used for an air conditioner, consists of a connecting pipe, a valve rod and a valve body, and is characterized in that an installment chamber of the valve rod is provided with a convex ring having a thread; a seal ring inside a groove on the valve rod is coordinately sealed with an internal surface inside the installment chamber of the valve rod; an outer thread on the valve rod is matched and transmitted with the thread on the convex ring; the other side of the valve rod is provided with a truncated conical surface; the side portion of a cold-medium passage opposite to the installment chamber of the valve rod is provided with a knife-withdrawing groove; the valve rod is stretched into the knife-withdrawing groove; the truncated conic surface at the right side of the valve rod is matched and sealed with a step positioned on the valve body. The utility model not only has a simple structure, but also has a good seal performance; correspondingly supplements a flow space inside the valve body, shortens the overall length of the stop valve and saves the materials because the knife-withdrawing groove is added in comparison with the other stop valves of the air conditioners.
Description
Technical field
The utility model relates to the closed stop valve of use in refrigeration system.
Background technique
At present, use the closed stop valve of a kind of use in refrigeration system, the sealing of valve body and valve rod chamber is adopted sealing seat, seal ring, is compressed bolt structure, seals.Complex structure adds man-hour, and operation is many, lavishes labor on waste material.
Summary of the invention
The objective of the invention is: a kind of use in refrigeration system stop valve is provided, not only has excellent sealing performance, and also simple in structure, easy to process, economical with materials.
The utility model is achieved in that a kind of use in refrigeration system stop valve, comprise adapter, valve body, valve rod, the fluorinfused nozzle nut, last cap nut, Female connector fittings, the non-return valve inside, right-hand member at valve rod has outside thread, it is conical that the right-hand member head is, the left end head of valve rod has an inner hexagonal hole, left end has a groove, seal ring is arranged in the groove, valve rod installation cavity chamber internal surface and valve rod fitted seal, its special way is: at the valve rod installation cavity one threaded annular projection is arranged, seal ring and valve rod installation cavity chamber internal surface fitted seal in the valve rod upper groove, screw-thread fit transmission on outside thread and the annular projection on the valve rod, the right-hand member head of valve rod is frustoconic shape; There is a tool withdrawal groove end with valve rod is installed the relative refrigerant passage of chamber, and the valve rod right-hand member stretches in the tool withdrawal groove, valve rod right-hand member head conical surface and the step contact matching sealing that is positioned at valve body.
The left end of valve rod has two grooves that seal ring is housed.
The utility model use in refrigeration system stop valve, fluted on the valve rod, seal ring is arranged in the groove, with valve rod cavity seal is installed, the screw-thread fit transmission of the projection that the screw thread of valve rod and valve rod installation cavity are indoor, the valve rod termination is stretched in the tool withdrawal groove, the step sealing on conical termination of valve rod and the valve body, so not only simple in structure, and has good seal performance; Compare owing to increased tool withdrawal groove with other use in refrigeration system stop valve, the corresponding interior flow space of valve body that increased makes the length integral body of this stop valve shorten, save material.
