Description
Technical field
It the utility model is related to valve technology field, more particularly to a kind of floating ball valve.
Background technology
The spheroid of floating ball valve is to float, and under the pressure of medium, spheroid can produce certain displacement and be pressed on out
On the sealing surface at mouth end, ensure port of export sealing, floating ball valve is mainly characterized by compact-sized, sealed reliable itself, structure
Simply, easy to maintenance, sealing surface, often in closure state, is not easy, by medium erosion, easily operated and maintenance, to be applied to sphere
The general work medium such as water, solvent, acid and natural gas, but also suitable for the severe medium of condition of work.
Prior art, ball valve can be divided into floating ball valve and fixing ball valve.Wherein, floating ball valve refers to the ball of ball valve
Body is to float, and under pressure medium effect, spheroid can produce certain displacement and be pressed on the sealing surface of the port of export, ensure
The port of export seals.When pressure is bigger, sealing property is also better, but starts the moment of torsion closed and increase with the increase of pressure.It is floating
The structure of dynamic spherical ball valve is simple, good airproof performance, but spheroid bears the load of working media and has all been transmitted to valve seat, therefore to consider
Can valve seat withstand the service load of spheroid medium, and when being extruded by elevated pressures, spheroid passes to the pressure of valve seat
Also can increase, flexible seat material shifts, and vibrations are larger, causes ball valve shakiness, prooving of valve seat increase, thus seals
Effect declines.
Utility model content
The technical problem that the utility model solves is to provide a kind of ball valve stabilization, wear-resisting shockproof floating ball valve.
In order to solve the above technical problems, the utility model provides a kind of floating ball valve, including valve body, spheroid, valve seat and
Upper valve rod, lower valve rod, form a medium flow channel and a medium flow pass in the valve body, the medium flow channel with
It is interconnected between the medium flow pass by a valve body cavity, the spheroid and the valve seat are placed in the valve body cavity
Interior, the upper valve rod, lower valve rod are connected with the spheroid are placed on the valve body respectively, be additionally provided with the valve seat one with
The elastic seal ring that the spheroid is in contact, the valve seat are connected by an aseismatic mechanism with the valve body；When the float ball
When valve closes, the spheroid floats with valve seat in the valve body cavity.
Further, the aseismatic mechanism is that a groove for being filled with the shockproof fillers of PE is set on the valve body.
Further, in addition to bonnet, the upper valve rod, lower valve rod and valve body, it is provided between valve body and bonnet
Seal.
Further, the seal is O-ring seal or V-shaped seal ring.
Further, a gap is included between the valve seat and the valve body, the spheroid can in the valve body cavity
Mobile distance is more than the gap.
Further, the valve seat is made up of metal or ceramics.
Further, in addition to by a support turbine apparatus being connected with the upper valve rod.
Further, the spheroid is the spherical valve core of steel alloy.
The floating ball valve of this case allows the floating ball valve to use larger sized because pressure is disperseed by multiple parts
In pipeline, under bigger pressure environment；Pressure is disperseed by multiple parts, make the service life of the floating ball valve it is longer, knot
Structure is more firm；Aseismatic mechanism ensure that valve inner when by high pressure, internal from vibrations, valve provided by the utility model
Seat and spheroid can be used under the adverse circumstances such as temperature, pressure is larger.
Brief description of the drawings
Fig. 1 is the structural representation of floating ball valve of the present utility model.
Embodiment
Embodiment of the present utility model is described below in detail, the example of the embodiment is shown in the drawings, wherein
Same or similar label represents same or similar element or the element with same or like function from beginning to end.Lead to below
It is exemplary to cross the embodiment being described with reference to the drawings, it is intended to for explaining the utility model, and it is not intended that to this practicality
New limitation.
As shown in figure 1, a kind of floating ball valve, including valve body 1, spheroid 2, valve seat 3 and upper valve rod 41, lower valve rod 42, valve body 1
An interior formation one medium flow channel 100 and medium flow pass 200, medium flow channel 100 and medium flow pass 200 it
Between by a valve body cavity 300 be interconnected, spheroid 2 and the valve seat 3 are placed in valve body cavity 300, upper valve rod 41, lower valve rod
42 are connected with spheroid 2 are placed on valve body 1 respectively, and an elastic seal ring 31 being in contact with spheroid 2 is additionally provided with valve seat 3,
Elastic seal ring 31 ensure that the elastic force between valve seat 3 and spheroid 2, make it be not easy to be worn when floating, valve seat 3 passes through one
Aseismatic mechanism 32 is connected with valve body 1；When floating ball valve closes, spheroid 2 floats with valve seat 3 in valve body cavity 300.
Aseismatic mechanism 32 is that a groove for being filled with the shockproof fillers of PE is set on valve body 1.
Also include bonnet 5, upper valve rod 41, lower valve rod 42 and valve body 1, seal is provided between valve body 1 and bonnet 5
11.Preferably, seal 11 is O-ring seal or V-shaped seal ring.With good seal performance, it is simple in construction, set rationally,
The advantages that low manufacture cost.
Include a gap 6 between valve seat 3 and valve body 1, the moveable distance in the valve body cavity 300 of spheroid 2 is more than institute
Gap 6 is stated, to ensure to keep a moving range between spheroid 2 and valve seat 3, without departing from scope.
Valve seat 3 is made up of metal or ceramics.Because valve seat 3 can equally float in valve body cavity 300, therefore this practicality is new
Valve body 1 uses rigid material in type.More enhance valve seat 3 service life of itself, and do not increase friction pressure, reduce because
The risk that sealing effectiveness caused by valve seat 3 damages is deteriorated.
Also include the turbine apparatus 8 being connected by a support 7 with upper valve rod 41, turbine apparatus 8 is used to adjust floating ball valve
Valve opening and keying.
Spheroid 2 be steel alloy spherical valve core, steel alloy is rigid material, it is ensured that spheroid 2 it is solid and reliable.
The floating ball valve of this case allows the floating ball valve to use larger sized because pressure is disperseed by multiple parts
In pipeline, under bigger pressure environment；Valve seat 3 employs rigid material, and pressure is disperseed by multiple parts, makes this floating
The service life of dynamic ball valve is longer, structure is more firm；Aseismatic mechanism 32 ensure that inside is exempted from inside valve body 1 when by high pressure
Shaken, valve seat 3 and spheroid 2 provided by the utility model can be used under the adverse circumstances such as temperature, pressure is larger.
It is described above, only it is most preferred embodiment of the present utility model, not the utility model is made any formal
Limitation, any those skilled in the art, in the case where not departing from technical solutions of the utility model ambit, utilization is above-mentioned
The method content of announcement makes many possible changes and modifications to technical solutions of the utility model, belongs to claim protection
