Abstract
The utility model relates to an arch-shaped diversion port ball valve which comprises a valve body, a valve seat, a valve rod, a ball body, a seal piece and an installation piece; the ball body is provided with a channel with the same diameter with a valve body channel; the ball body and the valve seat are in hard seal matching; arch-shaped diversion ports are respectively arranged at the inlet and the outlet of the ball body channel; the arch-shaped diversion ports are formed by respectively manufacturing a circular arc-shaped groove at the inlet and the outlet of the ball body channel; and the circular arc-shaped grooves are arranged at positions on the circumferences of the inlet and the outlet of the ball body channel which firstly enter the valve body channel in an early period in which the ball body is opened. In the initial stage in which the ball valve is opened and the final stage in which the ball valve is closed, a flowing area between the inlet and the outlet of the ball body channel and the valve seat is expanded, so that the flow rate of a medium is reduced, the erosion of the medium to the ball body and the valve seat is reduced, and the service life is prolonged. The arch-shaped diversion port ball valve is particularly applicable to the valve opening and closing under the working condition of abrasive media.
Description
Technical field
The utility model relates to valve field, specifically about a kind of ball valve.
Background technique
Advantage such as ball valve is simple in structure because of it, open-close convenient, flow resistance are little; Become the first-selected valve of each field medium transport pipeline; Its structure comprises valve body, valve seat, valve rod, spheroid, Sealing and assembling set, and spheroid is shaped on the manhole with the valve channel same diameter, when high temperature wear property medium operating mode is used; Its spheroid and valve seat adopt and are sealed and matched firmly; Valve seat with adopt floating structure, prevent that the stuck and media particle of valve seat high temperature in valve body to the wearing and tearing between spheroid and the sealing surface of seat, has characteristics such as high temperature resistant, wear-resisting.But, in initial period that ball valve is opened and the final stage of closing, forming oval-shaped passageway between spheroid channel entrance and outlet and the valve seat respectively, medium converges into high speed flow at this, very easily causes spheroid and valve seat to be washed away damage by medium, influences ball valve working life.
Summary of the invention
The purpose of the utility model is the problem that exists to existing technology, provides a kind of and wear-resistantly, anti-washes away, the arc flow-guiding mouth ball valve of long service life.
The technology contents of the utility model comprises valve body, valve seat, valve rod, spheroid, Sealing and assembling set; Spheroid is shaped on the passage with the valve channel same diameter; Spheroid and valve seat are sealed and matched firmly; Mainly be in the import of spheroid passage and outlet, to be shaped on arc flow-guiding mouth respectively; Said arc flow-guiding mouth is for making a circular groove at the spheroid channel entrance respectively with exporting, and the position of this circular groove is positioned at spheroid and opens the position that gets into valve channel on initial stage spheroid channel entrance and the outlet circumference at first.
The utility model has the advantages that the import at the spheroid passage is shaped on arc flow-guiding mouth respectively with exporting; In initial period that ball valve is opened and the final stage of closing; Circulation area between making between spheroid channel entrance and outlet and the valve seat enlarges; Reduce velocity of medium, reduce medium, raising working life the washing away of spheroid and valve seat.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the structural representation of spheroid among the utility model Fig. 1.
Embodiment
Arc flow-guiding mouth ball valve as shown in Figure 1; Comprise valve body 1, valve seat 2, valve rod 8, spheroid 3, Sealing and assembling set; Spheroid 3 is shaped on the passage with valve body 1 passage same diameter, and spheroid 3 is sealed and matched with valve seat 2 firmly, in the import of spheroid 3 passages and outlet, is shaped on arc flow-guiding mouth 9 respectively; Said arc flow-guiding mouth 9 is for making a circular groove at spheroid 3 channel entrances respectively with exporting; The position of this circular groove is positioned at spheroid 3 opens initial stage spheroid 3 channel entrances and exports the position that gets into valve body 1 passage on the circumference at first, that is to say that circular groove is in spheroid 3 channel entrances and the position that exports, when rotating from the closed condition to the opening state for spheroid 3; The position that breaks away from valve seat 2 sealing surfaces on its channel entrance and the outlet circumference at first; Make ball valve 3 open initial period and the circulation area increase of closing final stage, reduce velocity of medium, reduce medium washing away spheroid 3 and valve seat 2.The length of circular groove and the degree of depth are according to the size design of ball valve latus rectum, and be as shown in Figure 2.
Claims (1)
1. arc flow-guiding mouth ball valve; Comprise valve body (1), valve seat (2), valve rod (8), spheroid (3), Sealing and assembling set; Spheroid (3) is shaped on the passage with valve body (1) passage same diameter; Spheroid (3) is sealed and matched with valve seat (2) firmly; It is characterized in that being shaped on arc flow-guiding mouth (9) in the import of spheroid (3) passage respectively with exporting, said arc flow-guiding mouth (9) is for making a circular groove at spheroid (3) channel entrance respectively with exporting, and the position of this circular groove is positioned at spheroid (3) and opens the position that gets into valve body (1) passage on initial stage spheroid (3) channel entrance and the outlet circumference at first.
