Description
Technical field
The utility model relates to a kind of modulating valve, specifically a kind of single-seat adjusting valve.
Background technique
In automation control system, modulating valve, as the terminal actuating device in automatic regulating system, according to the command signal of control system, is regulated spool stroke by the actuator supporting with it, thereby reaches the object of adjust flux.Conventional single-seat adjusting valve structure is made up of valve body, valve seat, spool, valve gap, valve rod, filling body, fastening piece and Sealing.In the time that supporting actuator accepts control signal and carries out upper and lower straight-line displacement action, spool is positioned at below, and modulating valve is closed condition; Spool is positioned at top, and modulating valve is opening state.Because fluid inlet is often designed to arc shape, the ponding meeting effluent fluid import in maintenance process in influent stream road, not only gives environment, also can be harmful.
Model utility content
The purpose of this utility model has been to provide the single-seat adjusting valve of a kind of simple in structure, stable performance, long service life.
The technical solution of the utility model is:
A kind of single-seat adjusting valve, comprise valve body, valve gap, valve seat, spool, valve rod, described valve body is provided with fluid inlet, fluid output, described fluid inlet and fluid output are all curved channel, the inner connectivity part of described fluid inlet and fluid output is provided with valve seat, described valve body upper end is fixedly connected with the valve gap that has central passage, between described valve body and valve gap, be provided with liner clamp, described liner clamp center has the guide channel coaxial with valve gap central passage, in described valve body and valve gap, be provided with valve rod, described valve rod lower end is connected with spool, the other end of described valve rod stretches out outside valve gap through central passage, it is characterized in that: the valve body of described valve seat bottom is provided with filter screen, the bottom of described valve body has impurity removal port.
Described valve rod and valve gap upper wall joint are provided with balance spring, and described balance spring is provided with filler, on described filler, is pressed with Gland.
The outer surface of described spool lower end is arc surface.
Between described valve body and valve gap, be provided with the first sealing gasket, between valve body and liner clamp, be provided with the second sealing gasket.
Described valve seat bottom is connected with valve body screw thread, is provided with the 3rd sealing gasket between valve seat top and valve body.
The beneficial effects of the utility model are:
It is streamlined that single-seat adjusting valve of the present utility model fluid passage is S, and droop loss is little, and not only reasonable in design, valve seat are convenient to dismounting, and have be convenient to maintenance, can impurity screening, the advantage such as long service life.
