Abstract
The utility model relates to a flow-equalizing guide type valve core for a black water angle valve. The flow-equalizing guide type valve core comprises a valve core body (2), and is characterized in that at least one cylindrical surface (5) which is in clearance fit with the inner surface of a valve body (1) so as to realize the guide function is formed on the outer side face of the valve core body (2); a groove is formed at the upper end of the valve core body (2) and is connected with a valve rod; and a boss (6) which is in sealing fit with an opening of a valve seat (3) is formed at the lower end of the valve core body (2). When the flow-equalizing guide type valve core is used in the black water working conditions of the coal chemical industry, after high-temperature high-speed media enter the valve body (1) and are shunted by the valve core structure, the centrifugal force is eliminated, the direct medium flushing on the valve seat (3) is reduced, and the trial proves that the service life of the whole valve can be prolonged by 3 to 5 months. Due to the long guide structure of the valve core, the valve rod is stabilized, and the service life of the valve rod is prolonged. In addition, the surface of the valve core can be subjected to spraying or deposition treatment, and the wear resistance is improved.
Description
Technical field
The utility model relates to a kind of Heisui River angle valve with current-sharing guiding type spool.
Background technique
Existing Heisui River angle valve valve body adopts airflow design; Media flow is more smooth and easy; But medium at a high speed is after getting into valve body, owing to receive centrifugal action, the pipeline behind spool, valve seat and the valve is all produced serious erosion damage (referring to the breakage A in the accompanying drawing 1); Secondly, valve rod lacks guiding, under the impact of medium, produces vibration, even ruptures, and has seriously shortened the working life of valve.
The model utility content
The purpose of the utility model provides a kind of Heisui River angle valve with current-sharing guiding type spool, thereby can reduce medium directly washing away the life-span that prolongs whole deck valve door valve seat.
A kind of Heisui River angle valve is with current-sharing guiding type spool; Comprise the spool body; Its specialization is: thus on said spool body outer side surface, be provided with at least one barrel surface that play the guiding role with the valve interior surface Spielpassung; Thereby and have groove in spool body upper end and be connected with valve rod, be provided with the boss that is sealed and matched with the valve seat opening in spool body lower end.
Thereby wherein vertically be provided with at least 1 through hole and supply the medium circulation as pod apertures at spool body middle part.
Wherein vertically be provided with 2 through holes at spool body middle part, these 2 through holes are symmetrically distributed along the axis of spool body.
Wherein on said spool body outer side surface, be provided with two barrel surfaces with the valve interior surface Spielpassung.
After in the operating mode of Coal Chemical Industry Heisui River, adopting the utility model; High temperature, high speed medium receive the shunting action of valve core structure after getting into valve body, eliminated centrifugal force; Reduced medium to directly the washing away of valve seat, can make the life-span of whole deck valve door prolong 3～5 months through probationary certificate.The long guide structure of spool is firm valve rod, the working life of having improved valve rod.Spool face can spray in addition or molten applying handled, and improves wear resistance.
Description of drawings
Accompanying drawing 1 is the structural representation of background technique in the utility model;
Accompanying drawing 2 is the user mode schematic representation of the utility model;
Accompanying drawing 3 is the structural representation of spool body (2) in the utility model;
Accompanying drawing 4 is that the A of Fig. 3 is to view.
Embodiment
As shown in Figure 2; A kind of Heisui River angle valve comprises valve body 1, valve rear flange 4 and valve seat 3 with current-sharing guiding type spool, also comprises the spool body 2 that is installed in the valve body 1; Thereby on spool body 2 outer side surfaces, be provided with and cooperate at least one barrel surface 5 that play the guiding role with valve body 1 internal surface gaps; As shown in Figure 3, it is recessed that spool body 2 upper/lower terminals are provided with the intermediate portion of outstanding 5, two barrel surfaces 5 of two barrel surfaces; Thereby form spool and under the leading role of valve body 1 internal surface, stablize upper and lower moving, simultaneously also with regard to firm valve rod.
Like Fig. 3, shown in 4; (convenient in spool body 2 upper ends for describing; With an end that is connected with valve rod on the spool body 2 is the upper end; The corresponding the other end then is the lower end, and with accompanying drawing 2,3 in upper and lower to being consistent) thereby having groove is connected with valve rod, is provided with the boss 6 that is sealed and matched with valve seat 3 openings in spool body 2 lower ends.
As shown in Figure 4, vertically be provided with 2 through holes 7 at spool body 2 middle parts, these 2 through holes 7 are symmetrically distributed along the axis of spool body 2.After medium gets into valve body 1, thereby the shunting action minimizing that receives 2 through hole 7 structures in the spool is washed away.
Claims (4)
1. a Heisui River angle valve is with current-sharing guiding type spool; Comprise spool body (2); It is characterized in that: on said spool body (2) outer side surface, be provided with and cooperate at least one barrel surface (5) that play the guiding role with valve body (1) thereby internal surface gaps; And at spool body (2) thus the upper end has groove and is connected with valve rod, be provided with in spool body (2) lower end and boss (6) that valve seat (3) opening is sealed and matched.
2. Heisui River as claimed in claim 1 angle valve is characterized in that with current-sharing guiding type spool: wherein vertically be provided with at least 1 through hole (7) at spool body (2) middle part thus supply the medium circulation as pod apertures.
3. Heisui River as claimed in claim 2 angle valve is characterized in that with current-sharing guiding type spool: wherein vertically be provided with 2 through holes (7) at spool body (2) middle part, these 2 through holes (7) are symmetrically distributed along the axis of spool body (2).
4. it is characterized in that with current-sharing guiding type spool like any described Heisui River angle valve in the claim 1 to 3: wherein on said spool body (2) outer side surface, be provided with two barrel surfaces (5) that cooperate with valve body (1) internal surface gaps.
