Abstract
The utility model relates to a floating ball valve, which is characterized in that the floating ball valve comprises a left valve body (1), a right valve body (4), a ball body (5), a valve seat (6), a valve rod (9), a handle (15) and a plug (16), wherein the left valve body (1) is connected and combined with the right valve body (4) to form a valve body; the ball body (5) is arranged in the valve body and connected with the valve body through the valve seat (6); one end of the valve rod (9) is inserted into the valve body to be connected with the ball body (5), and the other end of the valve rod (9) is connected with the handle (15); and the plug (16) is connected with the right valve body (4). Compared with the prior art, the floating ball valve has the advantages of high sealing reliability, low probability of blockage, and the like.
Description
Technical field
The utility model relates to a kind of valve component, especially relates to a kind of floating ball valve.
Background technique
Ball valve is widely used in the industries such as rock gas, oil product, chemical industry, metallurgy, papermaking, electric power, mining industry, printing and dyeing, bio-pharmaceuticals, daily-use chemical industry, food machinery, water treatment and air-treatment, is the control mechanism of adjust flux.
The spheroid of floating ball valve floats, and under the pressure medium effect, spheroid can produce certain displacement and be pressed on the sealing surface of outlet end, guarantees the outlet end sealing.Floating ball valve simple in structure, good airproof performance has all been passed to the exit seal circle but spheroid bears the load of working medium, therefore will consider that can sealing ring material hold out against the work loads of spheroid medium, when being subject to the elevated pressures impact, spheroid may be offset.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of sealing reliability height, not susceptible to plugging floating ball valve for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of floating ball valve, comprise left valve barrel (1), right valve barrel (4), spheroid (5), valve seat (6), valve rod (9), handle (15) and plug (16), described left valve barrel (1) is connected with right valve barrel (4) and is combined as valve body, described spheroid (5) is located in the valve body, and be connected with valve body by valve seat (6), described valve rod (9) one ends insert valve body and are connected with spheroid (5), the other end is connected with handle (15), and described plug (16) is connected with right valve barrel (4).
Described left valve barrel (1) is connected 4 with right valve barrel) connect by double-screw bolt (3), and by nut (2) locking, be provided with between described left valve barrel (1) and the right valve barrel (4) and prevent the pad (7) revealed.
Be provided with filler (10) between described valve rod (9) and the valve body, described filler (10) is provided with the Gland (11) that compresses filler, and described Gland (11) is connected with valve body by screw (12).
Also be provided with the second pad (8) between described valve rod (9) and the valve body.
Be provided with limiting board (13) between described Gland (11) and the handle (15) and strengthen the check ring (14) of the screw-down torque when lever operated, described check ring (14) is the lip elastic seal ring.
Compared with prior art, the utlity model has following advantage:
1) uses lip elastic seal ring structural design, guarantee the reliability of sealing;
2) plug makes valve inner be difficult for stopping up as eduction gear, and when ball valve was in closed condition, the valve seat on right side made liquid barrier up and down, and the stagnant thing of valve body lumen can be drained by eduction gear;
When the rising phenomenon appearred in cavity pressure 3), the thrust of lumen medium energy dependence itself promoted valve seat and releasing pressure automatically, thereby guarantees the safety of valve body;
4) valve rod adopts the down-mounting type structure of back seal, and the sealing force of back seal increases and increases with pressure medium, thus can guarantee the reliable sealing of valve rod, and also when valve rod boosted unusually, valve rod can not spray.
