Abstract
A kind of single-seat adjusting valve, 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, described valve hole part comprises spool and valve rod, sets gradually the first seal ring, gland, the first back-up ring, the first wear ring, the second back-up ring, the second wear ring and the second seal ring between described valve rod and valve gap from top to bottom.Above-mentioned a kind of single-seat adjusting valve, structure is simple, reasonable in design, the first seal ring, gland, the first back-up ring, the first wear ring, the second back-up ring, the second wear ring and the second seal ring is set gradually from top to bottom between valve rod and valve gap, while playing sealing effect, valve rod and wear ring wear and tear hardly, thus improve reliability and the working life of product; In valve body, be fixedly installed piston guide bush, valve rod be fixedly installed the piston coordinated with piston guide bush, improve the stability regulated.
Description
Technical field
The utility model belongs to valve technology field, is specifically related to a kind of single-seat adjusting valve.
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.In traditional single-seat adjusting valve in valve rod and the long-term friction process of valve gap, valve rod is easy to wearing and tearing and is out of order, and the reliability of single-seat adjusting valve, sealing and working life are reduced.
Model utility content
For prior art Problems existing, the purpose of this utility model is to design the technological scheme providing a kind of single-seat adjusting valve.
Described a kind of single-seat adjusting valve, comprise 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, described valve hole part comprises spool and valve rod, it is characterized in that setting gradually the first seal ring, gland, the first back-up ring, the first wear ring, the second back-up ring, the second wear ring and the second seal ring between described valve rod and valve gap from top to bottom.
Described a kind of single-seat adjusting valve, it is characterized in that described gland by arrange screw and valve gap fix.
Described a kind of single-seat adjusting valve, 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.
Described a kind of single-seat adjusting valve, is characterized in that described spool is hollow valve core.
Above-mentioned a kind of single-seat adjusting valve, structure is simple, reasonable in design, the first seal ring, gland, the first back-up ring, the first wear ring, the second back-up ring, the second wear ring and the second seal ring is set gradually from top to bottom between valve rod and valve gap, while playing sealing effect, valve rod and wear ring wear and tear hardly, thus improve reliability and the working life of product; In valve body, be fixedly installed piston guide bush, valve rod be fixedly installed the piston coordinated with piston guide bush, improve the stability regulated.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-valve body; 2-valve seat; 3-spool; 4-piston guide bush; 5-valve gap; 6-second seal ring; 7-second wear ring; 8-second back-up ring; 9-actuator; 10-first seal ring; 11-gland; 12-first back-up ring; 13-first wear ring; 14-valve rod; 15-piston.
Embodiment
The utility model is further illustrated below in conjunction with Figure of description.
As shown in the figure, a kind of single-seat adjusting valve comprise valve body 1, 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 9 be connected with valve hole part.Wherein valve hole part comprises spool 3 and valve rod 14, and valve rod 14 is connected with actuator 9 through after valve gap 5.Be fixedly installed piston guide bush 4 in valve body 1, valve rod 14 be fixedly installed the piston 15 coordinated with piston guide bush 4.Piston guide bush 4 and piston 15 make the motion of valve rod 14 more stable.Spool 3 is hollow valve core, improves its sensitivity.In order to improve sealing and wear resistance, set gradually the first seal ring 10, gland 11, first back-up ring 12, first wear ring 13, second back-up ring 8, second wear ring 7 and the second seal ring 6 between valve rod 14 and valve gap 5 from top to bottom, wherein gland 11 is fixing with valve gap 5 by the screw arranged.
The working principle of above-mentioned a kind of single-seat adjusting valve is known technology, does not repeat at this.
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.
