Abstract
The utility model discloses a kind of ball valve, comprise valve body, described valve body offers orthogonal first connecting head and the second connecting head, described valve inner is provided with valve ball, on the valve body of described valve ball one end, be provided with sealing cover; Described valve body is provided with extension tube, is provided with rotating shaft in described extension tube, the two ends of described rotating shaft are connected with valve ball and switch respectively; The side of described extension tube is provided with limiting stopper.A kind of ball valve of the present utility model, valve body is provided with sealing cover, and sealing cover can be cleared up valve ball after opening; All offer contraction flow region in first fluid passage and in second fluid passage, contraction flow region can accelerate the flow velocity of the fluid by valve ball, reduces the generation of dirt in valve ball; Preserving and sealing layer on valve ball increases corrosion resistance and the sealing of valve ball, increases the working life of ball valve.
Description
technical field:
The utility model relates to a kind of ball valve.
background technique:
Ball valve all presents sphere at inlet/outlet place, thus block flowing.Because it is tight that ball valve only needs the operation of 90-degree rotation and very little moment of rotation just can close, and the runner that the body cavity opened completely to be medium provide resistance is very little, straight-through, have and be suitable for directly doing opening and closing use, also can be used as the use of throttling and control flow.Particularly its compact structure, is easy to Operation and maintenance, is applicable to water, solvent, acid and rock gas working medium.Go out at valve ball the accumulation that dirt easily occurs after but ball valve uses for a long time even to corrode, and existing ball valve cannot be cleared up valve ball very well, also cannot stop the corrosion of valve ball, makes the working life that ball valve cannot reach desirable.
summary of the invention:
The purpose of this utility model is to solve the problems of the prior art, provides a kind of corrosion protection, easy to clean, good airproof performance, and is convenient to the ball valve of installation.
In order to achieve the above object, the technical solution of the utility model is:
A kind of ball valve, comprise valve body, described valve body offers orthogonal first connecting head and the second connecting head, described valve inner is provided with valve ball, on the valve body of described valve ball one end, be provided with sealing cover; Described valve body is provided with extension tube, is provided with rotating shaft in described extension tube, the two ends of described rotating shaft are connected with valve ball and switch respectively; The side of described extension tube is provided with limiting stopper.
Offer first fluid passage in described first connecting head, offer second fluid passage in described second connecting head, described first fluid passage is connected by valve ball with second fluid passage.
All contraction flow region is offered in described first fluid passage and in second fluid passage.
Described switch comprises Switch main body, and described Switch main body is provided with joint, and described joint is provided with inserted part, described inserted part and limiting stopper activity clamping.
Described switch offers mounting hole, is provided with screw in described mounting hole, described screw and rotating shaft are fixedly linked.
Preserving and sealing layer is installed outside described valve ball.
The beneficial effects of the utility model are: a kind of ball valve of the present utility model, valve body is provided with sealing cover, and sealing cover can be cleared up valve ball after opening; All offer contraction flow region in first fluid passage and in second fluid passage, contraction flow region can accelerate the flow velocity of the fluid by valve ball, reduces the generation of dirt in valve ball; Preserving and sealing layer on valve ball increases corrosion resistance and the sealing of valve ball, increases the working life of ball valve.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
embodiment:
Embodiment 1
A kind of ball valve as shown in Figure 1, comprise valve body 1, described valve body 1 offers orthogonal first connecting head 2 and the second connecting head 3, described valve body 1 inside is provided with valve ball 4, be provided with preserving and sealing layer 9 outside described valve ball 4, preserving and sealing layer 9 adopts tetrafluoroethylene manufacture to form.On the valve body 1 of described valve ball 4 one end, be provided with sealing cover 5, sealing cover 5 can directly be cleared up valve ball 4 after opening.Described valve body 1 is provided with extension tube 6, is provided with rotating shaft 7 in described extension tube 6, the two ends of described rotating shaft 7 are connected with valve ball 4 and switch 8 respectively; The side of described extension tube 6 is provided with limiting stopper 61.
Offer first fluid passage 21 in described first connecting head 2, offer second fluid passage 31 in described second connecting head 3, described first fluid passage 21 is connected by valve ball 4 with second fluid passage 31.Contraction flow region 22 is all offered in described first fluid passage 21 with in second fluid passage 31.Contraction flow region 22 can accelerate the flow velocity by valve ball 4 fluid, reduces the generation of dirt in valve ball 4.
Described switch 8 comprises Switch main body 81, and described Switch main body 81 is provided with joint 82, and described joint 82 is provided with inserted part 83, described inserted part 83 and limiting stopper 61 activity clamping.Inserted part 83 can limiting rotating angle when switch 8 rotates, and guarantees not have deviation when controlling valve ball 4 break-make.Described switch 8 offers mounting hole 84, is provided with screw 85 in described mounting hole 84, described screw 85 is fixedly linked with rotating shaft 7.
A kind of ball valve of the present embodiment, valve body is provided with sealing cover, and sealing cover can be cleared up valve ball after opening; All offer contraction flow region in first fluid passage and in second fluid passage, contraction flow region can accelerate the flow velocity of the fluid by valve ball, reduces the generation of dirt in valve ball; Preserving and sealing layer on valve ball increases corrosion resistance and the sealing of valve ball, increases the working life of ball valve.
