Abstract
The invention relates to a novel black water angle valve. The novel black water angle valve comprises a valve body (1), a valve seat (3) and a valve core body (2) mounted in the valve body (1). The novel black water angle valve is characterized in that at least one cylindrical surface (5) which is in clearance fit with the inner surface of the valve body (1) for playing a guide role is arranged on the outer side surface of the valve core body (2), a groove is further formed at the upper end of the valve core body (2) for connecting with a valve rod, and a boss (6) which is in seal fit with an opening of the valve seat (3) is arranged at the lower end of the valve core body (2). After the novel black water angle valve disclosed by the invention is adopted under black water working conditions of the coal chemical industry, a high-temperature and high-speed medium is subject to the diversion role of the valve core structure after entering the valve body (1), then the centrifugal force is eliminated, the direct erosion of the valve seat (3) caused by the medium is reduced, and a trial proves that the service life of the whole valve can be prolonged by 3-5 months. A long guide structure of the valve core stabilizes the valve rod, thus the service life of the valve rod is prolonged. In addition, spray coating or melt coating processing can be performed on the surface of the valve core, thus the abrasion resistance is improved.
Description
Technical field
The present invention relates to a kind of novel Heisui River angle valve.
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.
Summary of the invention
The purpose of this invention is to provide a kind of novel Heisui River angle valve, thereby can reduce medium directly washing away the life-span that prolongs whole deck valve door valve seat.
A kind of novel Heisui River angle valve; Comprise valve body, valve seat; And be installed in the spool body in the valve 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 present invention; 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 among the present invention;
Accompanying drawing 2 is a structural representation of the present invention;
Accompanying drawing 3 is the structural representation of spool body (2) among the present invention;
Accompanying drawing 4 is that the A of Fig. 3 is to view.
Embodiment
As shown in Figure 2; A kind of novel Heisui River angle valve comprises valve body 1, valve rear flange 4 and valve seat 3, 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. novel Heisui River angle valve; Comprise valve body (1), valve seat (3); And be installed in the spool body (2) in the valve body (1); 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 to be 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. a kind of novel Heisui River as claimed in claim 1 angle valve is characterized in that: 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. a kind of novel Heisui River as claimed in claim 2 angle valve is characterized in that: 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. like any described a kind of novel Heisui River angle valve in the claim 1 to 3, it is characterized in that: 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.
