Abstract
The utility model discloses a balance pressure reducing valve, comprising a valve body, an inlet, an outlet and a cylinder cavity on the valve, a piston in the cylinder cavity of the valve, an adjustment signal device connected with the top of the piston by an O-shaped ring and a piston cover, a valve core of a valve seat connected with the end of the piston by a valve rod and the O-shaped ring, a sealing seat between the valve core of the valve seat, a sleeve arranged outside the valve core by the O-shaped ring, wherein the bottom of the valve core is connected with a bottom cover of the valve by a spring. The beneficial effects of the utility model are that: practicality, convenience, capacity for randomly controlling the air pressure in a tube during conveying the gas in the tube, more safety and stable outlet parameter.
Description
Technical field
The utility model relates to a kind of gas transmission pipeline valve, particularly a kind of balanced type reduction valve.
Background technique
In industrial production, often can use pipeline and come conveying gas, because gas is generally all explosive, so in the process of using, safety is extremely important.Gas guarantees that the pressure in the conveyance conduit is very important in the course of conveying of common pipe, general valve can only controlling plumbing fixtures in the middle of the process of using in the flow size of gas, can not demonstrate the pressure size of gas in pipeline.
Summary of the invention
At existing shortcoming, the utility model provides a kind of novel balanced type reduction valve.To achieve these goals, the measure taked of the utility model:
A kind of balanced type reduction valve, comprise valve body, valve body is provided with import, outlet and cylinder chamber, be provided with piston in the cylinder chamber of described valve body, the top of piston is connected with the regulated signal device by O type circle and piston cap, and the end of piston is connected on the spool of valve seat by valve rod and O type circle, and device has sealing seat between the spool of valve seat, the outside of spool is provided with sleeve by O type circle, and the bottom of spool links to each other with the bottom of valve body by spring;
Described inlet is connected with the inlet pressure display list by import pressure pipe, and the outlet port is connected with the outlet pressure display list by the feedback pressure conduit;
The outer side surface of described cylinder chamber is provided with the cylinder Exhaust screw;
Described valve seat is an inverted structure, and the sealing surface of spool is positioned at spool top, relies on the spring force sealing of spring.
The beneficial effects of the utility model: practicality, convenient, when carrying, gas can control the pressure of gas in the pipeline at any time well in pipeline, and safety and outlet parameter are stable more for safety more.
Description of drawings
Fig. 1, structural representation of the present utility model.
Embodiment
A kind of balanced type reduction valve, comprise valve body 6, valve body 6 is provided with import, outlet and cylinder chamber, be provided with piston 9 in the cylinder chamber of described valve body 6, the top of piston 9 is connected with regulated signal device 11 by O type circle and piston cap 14, and the end of piston 9 is connected on the spool 4 of valve seat 5 by valve rod 7 and O type circle, and device has sealing seat 18 between the spool 4 of valve seat 5, the outside of spool 4 is provided with sleeve 3 by O type circle, and the bottom of spool 4 links to each other with the bottom 1 of valve body 6 by spring 2; Described inlet is connected with inlet pressure display list 13 by import pressure pipe 16, and the outlet port is connected with outlet pressure display list 12 by feedback pressure conduit 10.Described valve seat 5 is an inverted structure, and the sealing surface of spool 4 is positioned at spool 4 tops, relies on the spring force sealing of spring 2.Only the utility model need be installed in the middle of the conveyance conduit of gas, come regulating piston 9 by regulating regulated signal device 11, impel piston 9 to move downward and promote spool 4, thereby reach the pressure of the gas of its outlet of control gaseous, and its pressure can show on inlet pressure display list 13 and outlet pressure display list 12; The outer side surface of described cylinder chamber is provided with cylinder Exhaust screw 8; When being in an emergency, can be by regulating the gas that cylinder Exhaust screw 8 is got rid of in the cylinder chamber, thus realize the purpose of this utility model.
Those skilled in the art's simple change and replacement in the present technique field all are within the protection domain of the present utility model.
