Description
Technical field
The present invention relates 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, using spheroid
The purpose for realizing opening and closing is rotated by 90 ° around the axis of valve rod, except for the difference that faucet body is spheroid, there is 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
Portion is presented sphere, so as to block flowing.Ball valve is mainly used to make the flow direction for cutting off, distribute and changing medium in pipeline.
In 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 and valve seat between.But, when the temperature of fluid is relatively low, due to expanding with heat and contract with cold for spheroid, spheroid can be caused with sealing
Pad departs from, and so as to produce gap, causes fluid leakage.In addition existing ball valve is subject to be taken in fluid after a long time use
The particulate matter abrasion of band, reduces the service life of pipeline and ball valve.
The content of the invention
The present invention is in order to solve problem of the prior art, there is provided one kind is prevented from fluid leakage, and operation needs torsion
Ball valve that is less, effectively increasing the service life.
Concrete technical scheme is as follows：A kind of ball valve, including valve body, fluid passage and spheroid, the spheroid is arranged on valve body
Accommodating chamber in and in fluid passage, sealing gasket is provided between the spheroid and valve body, sealing gasket is arranged on valve body, institute
Sealing gasket is stated including segmental arc and terminal part, distal portion sets 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 below the attached technical scheme of the present invention.
Preferably, the angle is 4 ° to 7 °.
Preferably, fluid cavity is provided with the spheroid, polylith baffle plate is provided with fluid cavity, baffle interval is arranged,
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 bends downwards.
The technique effect of the present invention：The ball valve of the present invention can reduce required torsion when making ball valve in control, so as to just
In operation；Meanwhile, it is capable to prevent the leakage expanded with heat and contract with cold between caused spheroid and valve body；Furthermore it is possible in fluid-absorbent
Particulate matter, reduces abrasion of the particulate matter to pipeline and ball valve, further lifts the service life of ball valve.
Description of the drawings
Fig. 1 is the schematic diagram of the ball valve of the embodiment of the present invention.
Fig. 2 is the enlarged drawing of M parts in Fig. 1.
Fig. 3 is that embodiment of the present invention ball valve does not have the out-of-date sealing gasket schematic diagram of fluid stream.
Fig. 4 is that embodiment of the present invention ball valve has the out-of-date sealing gasket schematic diagram of fluid stream.
Specific embodiment
Below, the substantive distinguishing features and advantage of the present invention are further described with reference to example, but the present invention not office
It is 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 is provided between the spheroid 3 and valve body 1, is sealed
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 with the spaced 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 no fluid stream is out-of-date in ball valve, terminal part 42 is upwarped, and spheroid is only contacted with terminal part, contact
Area is less, so that resistance is less when adjusting ball position, is easy to user to adjust.When fluid passes through, 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
Body increases with the contact area of sealing gasket, so as to prevent fluid so as to the gap between spheroid and sealing gasket spills.
As shown in Figures 1 to 4, fluid cavity 31 is provided with the spheroid 3, polylith baffle plate 5, baffle plate 5 is provided with fluid cavity 31
Interval setting, the baffle plate 5 is provided with through hole 51, and fluid is mutually converged after the injection of through hole with the fluid between baffle plate 5, while
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, can keep away
Exempt from the steam bubble impact metallic surface for rupturing, fluid is not directly to impact metal surface, so as to reducing the destruction of cavitation and making an uproar
The impact of sound.The baffle plate 5 is made up of magnetic material, metallic particles small in the fluid-absorbent of baffle plate 5 is enable, so as to reduce
Particulate matter quantity in fluid, extends the service life of pipeline.The end of the baffle plate 5 is provided with folding portion 52, folding portion 52 to
Lower bending.Angle is formed between folding portion and baffle plate, so that baffle plate can be subject to the equilibrant force that fluid impact is formed, can be reduced
The torsion of spheroid motion, is easy to adjust.
The ball valve of the present embodiment can reduce required torsion when making ball valve in control, consequently facilitating operation；Meanwhile, it is capable to
Prevent the leakage expanded with heat and contract with cold between caused spheroid and valve body；Furthermore it is possible to the particulate matter in fluid-absorbent, reduces particulate matter
Abrasion to pipeline and ball valve, further lifts the service life of ball valve.
It is pointed out that above-mentioned preferred embodiment technology design only to illustrate the invention and feature, its object is to
Allow person skilled in the art will appreciate that present disclosure and implement according to this, protection of the invention can not be limited with this
Scope.All equivalence changes made according to spirit of the invention or modification, all should be included within the scope of the present invention.
