Abstract

The utility model discloses an anti-blocking ball valve which comprises a valve body and a valve rod. The valve rod is arranged above the valve body, a valve seat and a ball are arranged in the valve body, the ball is arranged in the valve seat, a valve seat flow channel is formed in the valve seat, the valve seat flow channel is matched with fluid flow channels connected with the two ends of the valve seat, a ball flow channel matched with the valve seat flow channel is formed in the ball, and the ball flow channel and the valve seat flow channel are all fillet square holes. The cross sections of the ball flow channel and the valve seat flow channel are the fillet square holes, erosion of fluid to the ball and the valve seat can be reduced due to arrangement of fillets, the flowing area can be larger through the square holes, the speed of the fluid is reduced, ball opening erosion is greatly reduced, abrasion of the ball valve is lowered, and the service life of the ball valve is prolonged.

Description

A kind of anticlogging ball valve
Technical field
The utility model relates to a kind of ball valve, is specifically related to a kind of anticlogging ball valve.
Background technique
Ball valve is that spheroid is driven by valve rod, and the valve rotating around the axis of valve rod.Side's work valve utilization also can be used for adjusting and the control of fluid, wherein firmly seals between its V-type ball core of V-type ball valve and the metal seat valve of pile-up welding hard alloy and has very strong shearing force, is specially adapted to the medium such as fibre-bearing, small solid particle.And multi-pass ball valve not only switching of the interflow of control media, shunting and the flow direction flexibly on pipeline, the while also can be closed arbitrary passage and two other passage is connected.
In China, ball valve is widely used in industries such as petroleum refining, long-distance transport pipes, chemical industry, papermaking, pharmacy, water conservancy, electric power, municipal administration, iron and steel, occupies very important status in national economy.It has the action of 90-degree rotation, and faucet body is spheroid, has manhole or passage by its axis.Ball valve is mainly used to make the flow direction that cuts off, distributes and change medium in pipeline, and it only need to just can be closed tightly by the operation of 90-degree rotation and very little moment of rotation.Ball valve optimum makees switch, cut-off valve uses, V-type ball valve.
The hole of existing valve seat and spheroid is the circle of standard, and under the little aperture state of valve, the souring power at fluid convection current road junction is very large, to having a significant impact the working life of valve.And ball valve in the past all adopts the mode of welding, can not ensure the sealing combination property, particularly gas medium of valve body.
Model utility content
The utility model provides the cross-section area of a kind of spheroid runner and valve seat runner to be the ball valve of fillet square hole, the setting of fillet can slowing down fluid washing away spheroid valve seat, and square hole can provide larger circulation area, reduce rate of flow of fluid, greatly less ball mouth washes away, reduce the wearing and tearing of ball valve, extended the working life of ball valve.
The purpose of this utility model reaches by the following technical programs:
A kind of anticlogging ball valve, comprise valve body, valve rod, valve rod is arranged on valve body top, in described valve body, be provided with valve seat and spheroid, in valve seat, be provided with spheroid, in valve seat, be provided with valve seat runner, valve seat runner matches with the fluid course that valve seat two ends are connected, in spheroid, be provided with the spheroid runner matching with valve seat runner, the runner of described spheroid runner and valve seat runner is square hole, and is fillet square hole.
Four jiaos of radians of the cross section of described spheroid runner and valve seat runner are 0.8-1.5 °.
Described valve seat comprises valve seat A, valve seat middle part and valve seat B, and valve seat A, valve seat middle part and valve seat B are linked in sequence into a spherical hollow space solid forging that spheroid is installed.
The fluid course that valve seat A is connected and valve seat A are also provided with a round platform passage, and large one end of round bottom face diameter of round platform passage is connected with valve seat A.
The material of described spheroid and valve seat is identical.The material of spheroid and valve seat is identical can ensure that material thermal expansion coefficient is consistent, can keep sealability.
The utility model compared with prior art, there is following advantage and beneficial effect:
The utility model is provided with spheroid runner and the valve seat runner of fillet square hole, make under little aperture 0-15 ° opening (being the scope that spheroid valve seat is easily washed away) state, fillet square hole can provide Geng great road to lead to area, and four jiaos of square holes be circular-arc be the setting of fillet, can alleviate fluid washing away spheroid and valve seat, further reduce rate of flow of fluid, thereby can reduce the wearing and tearing of runner mouth, extend the working life of ball valve.
Brief description of the drawings
Fig. 1 is the schematic diagram of fillet square hole of the present utility model;
Fig. 2 is overall schematic of the present utility model.
Embodiment
Embodiment 1
As depicted in figs. 1 and 2, a kind of anticlogging ball valve, comprise valve body 1, valve rod, valve rod is arranged on valve body 1 top, is provided with valve seat 2 and spheroid 3 in valve body 1, in valve seat 2, be provided with spheroid 3, in valve seat 2, be provided with valve seat runner 4, valve seat runner 4 matches with the fluid course 5 that valve seat 2 two ends are connected, and is provided with the spheroid runner 6 matching with valve seat runner 4 in spheroid 3, the runner of described spheroid runner 6 and valve seat runner 4 is square hole, and is fillet square hole.
The cross-section area of spheroid runner 6 is made as to rounded square, because valve is under little aperture 0-15 ° opening (being the scope that spheroid valve seat is easily washed away) state, fillet square hole can provide Geng great road to lead to area, and four jiaos of square holes be circular-arc be the setting of fillet, can alleviate fluid washing away spheroid 3 and valve seat 2, further reduce rate of flow of fluid, thereby can reduce the wearing and tearing of runner mouth, extend the working life of ball valve.
Embodiment 2
As shown in Figure 1, the present embodiment is on embodiment 1 basis, and further, four jiaos of radians of the cross section of spheroid runner and valve seat runner are 0.8-1.5 °.The fillet square hole of this radian scope can be alleviated fluid preferably to the washing away of spheroid 3 and valve seat 2, and better extends the working life of ball valve.
