Abstract
The invention relates to a ball valve, which comprises a valve body, a valve ball, a valve seat and a valve rod, wherein the valve seat divides the surface of the valve ball into a sealed surface and a communicated surface; a dished scraper is arranged between the valve seat and the sealed surface of the valve ball; and an annular scraper is arranged between the valve seat and the communicated surface of the valve ball. The dished scraper is arranged between the valve seat and the sealed surface of the valve ball, and the annular scraper is arranged between the valve seat and the communicated surface of the valve ball, so that in actual use, the ball valve can effectively scrape hard impurities passing or being deposited on the surface of the ball body, ensure the smoothness of the surface of the ball body, make the sealing property of the ball valve more reliable, and prolong the service life of the ball valve.
Description
Technical field
The present invention relates to a kind of ball valve, relate in particular to the metal hard-sealing ball valve that uses under the special media.
Background technique
We know that in fields such as oil, chemical industry, iron and steel, metallurgy and electric power, ball valve is widely used.It mainly plays the medium that blocks or connect in the pipeline; and these occasions are normally with hard solid particle medium, easily coking, easy medium occasion of pasting; after using for a long time; ball surface in the ball valve can deposit some harder sedimentss usually; if after the untimely processing, valve ball rotation, the fixing continuous valve seat that seals mutually of friction and valve ball of impurity in rigid sediments on the sphere or the fluid; sealing between valve seat and the valve ball can not get guaranteeing, influences the normal use of ball valve.
Summary of the invention
Thereby the present invention seeks to provide a kind of and can effectively strike off the ball valve that the ball surface foul guarantees reliable sealing in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution used in the present invention is: a kind of ball valve, comprise along its axially offer through hole valve body, be arranged in the valve body and the center have the hole valve ball, be arranged between valve ball and the valve body and seal valve seat that described valve ball can relative its rotation, the valve rod that links and be connected with described valve ball, described valve seat is divided into sealing surface and connected surface with described ball surface, between described valve seat and valve ball sealing surface, be provided with dish-shaped scraper, between the connected surface of described valve seat and valve ball, be provided with annular scraper.
Further, described valve seat is positioned at the both sides of valve ball, is respectively arranged with described dish-shaped scraper and annular scraper on the described valve seat in both sides.
Also be provided with the dish spring between described valve seat and the valve body.
Because technique scheme utilization, the present invention compared with prior art has following advantage: the present invention is by being provided with the butterfly scraper between the sealing surface of valve ball and valve seat, between the connected surface of valve ball and valve seat, annular scraper is set, in actual use, can strike off the hard foreign material that pass through or be deposited on the spherome surface effectively, guarantee the slickness of spherome surface, make that the sealability of ball valve is more reliable, and prolonged the working life of ball valve.

Embodiment
Below in conjunction with accompanying drawing the preferred embodiment of the invention is elaborated:
Ball valve as shown in Figure 1, it mainly comprises valve body 1, valve ball 3, valve seat 4, valve rod 5, support 20 and operating grip 10, wherein, valve body 1 is mainly formed by the valve gap 13 that bolt 14 is fixedly connected by valve body 12 and with valve body 12, whole valve body 1 axially is formed with through hole 11, valve ball 3 is arranged in the through hole 11 at valve body 1 center, and valve ball 3 also offers porose 31 along its center.Valve seat 4 is arranged on the both sides of valve ball 3, thereby it is separated into two-part with valve ball 3 surfaces: sealing surface 32 and connected surface 33.In order further to guarantee between valve body 12 and valve seat 4, also to be provided with dish spring 8 by sealing effect.
One end of the upper end of valve ball 3 and valve rod 5 is fixedly connected, and the centre of valve rod 5 is fixedly connected by Glan lid 40 and valve body 1, and anti-extrusion filler 30 forms with stuffing box packing 50 and the sealing of valve body 1 by filling, and sees Fig. 2.The fixedly connected joint sleeve 9 in the upper end of valve rod 5, the upper fixed of joint sleeve 9 connects the operating grip 10 around valve rod 5 axial rotation.Between joint sleeve 9 and valve body 1 upper end, also be fixedly connected with limit bracket 20.
In the present embodiment, be provided with dish-shaped scraper 71 between the sealing surface 32 of every side valve seat 4 and valve ball 3, as shown in Figure 3, its blade also contacts with the surface of valve ball 3 all the time towards the surface of valve ball 3; Between the connected surface 33 of every side valve seat 4 and valve ball 3, also be provided with annular scraper 72, as shown in Figure 4, its blade also also contacts with valve ball 3 all the time towards the surface of valve ball 3, when spheroid rotated, dish-shaped scraper 71 was scraped 72 the particulate matter that can scrape off effectively attached to spherome surface that cooperates with annular.
Concrete working procedure is as follows: during proper functioning, ball valve is installed in the middle of the system pipeline, MEDIA FLOW is in the through hole 11 of valve body 1, rotating operation handle 10, valve rod 5 rotates, and rotates together thereby drive valve ball 3, when turning to its hole 31, valve ball 3 is connected with the through hole 11 of valve body 1, then valve is in open mode, blocks the firmly through hole 11 of valve body 1 when the surface of valve ball 3, and then valve is in closed condition.
