Abstract
Piston, as a single-seat adjusting valve for balancing component, belongs to valve technology field.It comprises valve body, the valve gap be fixedly connected with valve body, the valve seat be arranged in valve body, the valve hole part coordinated with valve seat and the actuator be connected with valve hole part, valve hole part comprises spool and valve rod, piston guide bush is fixedly installed in valve body, valve rod is fixedly installed the piston coordinated with piston guide bush, O-ring seals is equipped with between piston and piston guide bush, in valve rod, center hole is set, center hole lower end communicates with the medium holes that enters be arranged on bottom spool, and center hole upper end communicates with valve gap inner chamber.The utility model is by valve rod being set up piston and center, valve body sets up piston guide bush, forms pressure self-balancing structure, eliminate the unbalanced force of medium when high pressure difference to valve hole part, make the adjusting function of whole valve not by the impact of pressure medium fluctuation, improve precision.In addition, in spool, be provided with looping pit, expand the orifice size of spool, improve stability.
Description
Technical field
The utility model belongs to valve technology field, is specifically related to the single-seat adjusting valve of a kind of piston as balancing component.
Background technique
Single-seat adjusting valve is the controlling component in pipeline fluid transporting system, and it is used to change face, forehearth section and media flow direction, has the functions such as water conservancy diversion, cut-off, throttling, non-return.Existing single-seat adjusting valve valve hole part is comparatively simple, and in actual moving process, the medium of high pressure difference can produce unbalanced force to valve hole part, and the adjusting function of whole valve is comparatively large by the impact of pressure medium fluctuation, affects precision.
Model utility content
For prior art Problems existing, the purpose of this utility model is to design provides a kind of piston as the technological scheme of the single-seat adjusting valve of balancing component.
Described a kind of piston is as the single-seat adjusting valve of balancing component, comprise valve body, the valve gap be fixedly connected with valve body, be arranged on the valve seat in valve body, the valve hole part coordinated with valve seat and the actuator be connected with valve hole part, described valve hole part comprises spool and valve rod, it is characterized in that being fixedly installed piston guide bush in described valve body, described valve rod is fixedly installed the piston coordinated with piston guide bush, O-ring seals is equipped with between described piston and piston guide bush, in described valve rod, center hole is set, described center hole lower end communicates with the medium holes that enters be arranged on bottom spool, described center hole upper end communicates with valve gap inner chamber.
Described a kind of piston, as the single-seat adjusting valve of balancing component, is characterized in that being provided with looping pit in described spool.
Described a kind of piston, as the single-seat adjusting valve of balancing component, is characterized in that described center hole upper end outlet is positioned at above piston.
Above-mentioned a kind of piston is as the single-seat adjusting valve of balancing component, structure is simple, reasonable in design, by valve rod being set up piston and center, valve body sets up piston guide bush, forms pressure self-balancing structure, eliminate the unbalanced force of medium when high pressure difference to valve hole part, make the adjusting function of whole valve not by the impact of pressure medium fluctuation, improve precision.In addition, in spool, be provided with looping pit, expand the orifice size of spool, improve stability.

Embodiment
Furthermore bright the utility model is carried out below in conjunction with Figure of description.
As shown in the figure, a kind of with piston comprise valve body 1 as the single-seat adjusting valve of balancing component, the valve gap 5 be fixedly connected with valve body 1, the valve seat 2 be arranged in valve body 1, the valve hole part coordinated with valve seat 2 and the actuator 6 be connected with valve hole part, wherein valve hole part comprises spool 3 and valve rod 9.Be fixedly installed piston guide bush 4 in valve body 1, valve rod 9 be fixedly installed the piston 8 coordinated with piston guide bush 4, between piston 8 and piston guide bush 4, be equipped with O-ring seals 7.Like this, piston 8 just can slide up and down in piston guide bush 4.Meanwhile, arrange center hole 10 in valve rod 9, described center hole 10 lower end communicates with the medium holes 11 that enters be arranged on bottom spool 3, and center hole 10 upper end outlet to be positioned at above piston 8 and to communicate with valve gap 5 inner chamber.Above-mentioned piston 8, piston guide bush 4 and center hole 10 form pressure self-balancing structure, eliminate the unbalanced force of medium when high pressure difference to valve hole part, make the adjusting function of whole valve not by the impact of pressure medium fluctuation, improve precision.Be provided with looping pit 12 in spool 3, expand the orifice size of spool 3, improve stability.
Below be only described with regard to the utility model preferred embodiment, but can not be interpreted as it is limitations on claims.The utility model is not only confined to above embodiment, and its concrete structure allows to change.All various changes done in the protection domain of the utility model independent claims are all in protection domain of the present utility model.
