Description
Technical field
The utility model is related to a kind of control valve, more particularly to a kind of ball valve.
Background technology
Ball valve is a kind of novel valve being widely adopted in recent years, and the opening and closing element of ball valve is a spheroid, utilizes spheroid
The purpose realized and opened and closed is rotated by 90 ° around the axis of valve rod, the difference is that faucet body is spheroid, has manhole or logical
Road passes through its axis.The ratio of sphere and passway should be such, i.e., when 90 degree of ball rotation, should be complete at import and export
Sphere is presented in portion, so as to block flowing.Ball valve is mainly used to make the flow direction for cutting off, distributing and changing medium in pipeline.
In the prior art, sealing structure, such as sealing gasket are typically provided between the spheroid and valve seat of ball valve, so as to prevent fluid from spheroid
Leakage between valve seat.But, when the temperature of fluid is relatively low, due to expanding with heat and contract with cold for spheroid, spheroid and sealing can be caused
Pad departs from, so as to produce gap, causes fluid leakage.In addition existing ball valve is subject to take in fluid after a long time use
The particulate matter abrasion of band, reduces the service life of pipeline and ball valve.
Utility model content
The utility model can prevent fluid leakage to solve problem of the prior art there is provided one kind, and operation needs
Torsion is smaller, the ball valve effectively increased the service life.
Concrete technical scheme is as follows：A kind of ball valve, including valve body, fluid passage and spheroid, the spheroid are arranged on valve body
Accommodating chamber in and in the fluid passage, sealing gasket is provided between the spheroid and valve body, sealing gasket is arranged on valve body, institute
Stating sealing gasket includes segmental arc and terminal part, and distal portion is set in the end of segmental arc, the segmental arc with spherome surface interval
Put, the terminal part is contacted with spherome surface, there is angle, the folder between the bottom surface of the terminal part and the supporting surface of valve body
Angle is acute angle.
It is attached technical scheme of the present utility model below.
Preferably, the angle is 4 ° to 7 °.
Preferably, it is provided with the spheroid in fluid cavity, fluid cavity and is provided with polylith baffle plate, baffle interval is set,
The baffle plate is provided with through hole.
Preferably, the baffle plate is made up of magnetic material.
Preferably, the end of the baffle plate is provided with folding portion, and folding portion is bent downwards.
Technique effect of the present utility model：Ball valve of the present utility model is turned round needed for can reducing when making ball valve in control
Power, consequently facilitating operation；Meanwhile, it is capable to prevent the leakage caused by expanding with heat and contract with cold between spheroid and valve body；Furthermore it is possible to adsorb
Particulate matter in fluid, reduces abrasion of the particulate matter to pipeline and ball valve, further the service life of lifting ball valve.
Brief description of the drawings
Fig. 1 is the schematic diagram of the ball valve of the utility model embodiment.
Fig. 2 is the enlarged drawing of M parts in Fig. 1.
Fig. 3 is that the utility model embodiment ball valve does not have the out-of-date sealing gasket schematic diagram of fluid stream.
Fig. 4 is that the utility model embodiment ball valve has the out-of-date sealing gasket schematic diagram of fluid stream.
Embodiment
Below, substantive distinguishing features of the present utility model and advantage are further described with reference to example, but this practicality is new
Type is not limited to listed embodiment.
As shown in Figures 1 to 4, the ball valve 100 of the present embodiment includes valve body 1, fluid passage 2 and spheroid 3, the spheroid 3
It is arranged in the accommodating chamber 11 of valve body 1 and in fluid passage 2.Sealing gasket 4, sealing are provided between the spheroid 3 and valve body 1
Pad 4 is arranged on valve body 1, and the sealing gasket 4 includes segmental arc 41 and terminal part 42, and terminal part 42 is located at the end of segmental arc 41
End.The segmental arc 41 is arranged at intervals with the surface of spheroid 3, and the terminal part 42 is contacted with the surface of spheroid 3, the terminal part 42
There is angle a, the angle is acute angle between the supporting surface 11 of bottom surface and valve body 1.In the present embodiment, the angle be 4 ° extremely
7°.In above-mentioned technical proposal, when not having fluid stream out-of-date in ball valve, terminal part 42 is upwarped, and spheroid is only contacted with terminal part, contact
Area is smaller, so that resistance is smaller during regulation ball position, is easy to user to adjust.When fluid by when, due to fluid temperature
Degree so that spheroid produces deformation, spheroid is pushed, and oppresses terminal part, so that segmental arc and terminal part are all fitted with spheroid, ball
The contact area increase of body and sealing gasket, so as to prevent fluid from being spilt so as to the gap between spheroid and sealing gasket.
As shown in Figures 1 to 4, it is provided with the spheroid 3 in fluid cavity 31, fluid cavity 31 and is provided with polylith baffle plate 5, baffle plate 5
It is arranged at intervals, the baffle plate 5 is provided with through hole 51, the fluid after the injection that fluid passes through through hole between baffle plate 5 mutually converges, simultaneously
The fluid of upper and lower baffle plate mutually converges between baffle plate, is formed and assembles injection.So as to form a buffering in a liquid, it can keep away
Exempt from the steam bubble impact metallic surface of rupture, fluid is not directly to impact metal surface, so as to reduce the destruction of cavitation and make an uproar
The influence of sound.The baffle plate 5 is made up of magnetic material, enables metallic particles small in the fluid-absorbent of baffle plate 5, so as to reduce
Particulate matter quantity in fluid, extends the service life of pipeline.The end of the baffle plate 5 be provided with folding portion 52, folding portion 52 to
Lower bending.Angle is formed between folding portion and baffle plate, so that the equilibrant force that baffle plate can be formed by fluid impact, can be reduced
The torsion of spheroid motion, is easy to regulation.
Torsion needed for the ball valve of the present embodiment can reduce when making ball valve in control, consequently facilitating operation；Meanwhile, it is capable to
Prevent the leakage between spheroid and valve body caused by expanding with heat and contract with cold；Furthermore it is possible to which the particulate matter in fluid-absorbent, reduces particulate matter
The service life of abrasion to pipeline and ball valve, further lifting ball valve.
It is pointed out that above-mentioned preferred embodiment is only explanation technical concepts and features of the present utility model, its purpose
It is person skilled in the art can understand content of the present utility model and according to this implement, this reality can not be limited with this
With new protection domain.All equivalent change or modifications made according to the utility model Spirit Essence, should all cover in this reality
Within new protection domain.
