Abstract
The utility model discloses a detachable piston type pressure reducing valve. The pressure reducing valve comprises a shell, an adjusting rod and a spring. The shell comprises a safety hood, a cap, a bonnet, a valve body and an end cover, wherein the safety hood, the cap, the bonnet, the valve body and the end cover are sequentially connected from top to bottom, the cap is covered by the safety hood, the cap is fastened to the bonnet through a bolt I, the bonnet is fixed to the valve body through a bolt II and a positioning pin, the end cover is fixed to the valve body through a clamp nut, and a plug screw is further arranged on the end cover. The detachable piston type pressure reducing valve has the advantages that the detachable piston type pressure reducing valve is simple and compact in structure, easy to operate and long in service life; due to the facts that the shell is detached into the safety hood, the cap, the bonnet, the valve body and the end cover, and then the safety hood, the cap, the bonnet, the valve body and the end cover are sequentially fastened, the valve is easy and convenient to detach.
Description
Technical field
The utility model relates to a kind of valve field, relates in particular to a kind of detachable Piston reducing valve.
Background technique
Reduction valve is by regulating, inlet pressure being reduced to the outlet pressure of a certain needs, and rely on the energy of medium itself, makes outlet pressure automatically keep stable valve.Along with the market demand of reduction valve is increasing; the kind of reduction valve is also more and more; Piston reducing valve should be educated and be given birth to; Piston reducing valve is the flow that the aperture of the open-shut device in employing control valve body regulates medium, by the pressure decreased of medium, regulates the aperture of open-shut device by the effect of downstream pressure simultaneously; downstream pressure is kept within the specific limits; in the situation that inlet pressure constantly changes, keep outlet pressure in the scope of setting, utensil is produced in protection life thereafter.This class valve generally should level be installed in pipeline.Reduction valve shell used is integral type in the market, dismantles very inconvenient.Therefore, need a kind of new technological scheme to address the above problem.
