Description
Technical field
The utility model belongs to valve arrangement technical field, especially relates to a kind of intelligent breathing ball valve.
Background technique
At present, ball valve is mainly used to cut off, distributes and the flow direction of cover plate medium in pipeline.Ball valve is little with fluid resistance, structure is simple, the sealing surface of spheroid and valve seat and medium are isolated, passage is smooth, not easily deposition medium, and be not only applicable to general work medium, but also be applicable to the severe medium of operating conditions, be widely used in the every field such as oil, chemical industry, generating, papermaking, atomic power, aviation, rocket, and in daily life.
The valve body of ball valve can be overall, also can be knockdown.Prior art uses fixing spherical ball valve at the bigbore environment of high pressure, and the upper lower rotary shaft of this ball valve, is fixed on spheroid, so spheroid is also fixing, does not produce movement after pressurized, is used in high-pressure large-caliber environment.Because fixing spherical ball valve is all with the valve seat floated, after being subject to pressure medium or spring action, valve seat produces mobile, makes seal ring be pressed on spheroid, and to ensure sealing, but spheroid is fixing, and valve seat is pressed on spheroid all the time.So valve seat and ball seal face exist the problem of wearing and tearing all the time, working life is short, and switching process belongs to dynamic seal (packing) process, and valve seat dynamic stress easily causes sealing uneven and outlet is revealed, and sealing reliability is poor; In the small-bore Environmental Conditions of mesolow is floating ball ball valve, and the spheroid of this ball valve is floating, and under pressure medium effect, spheroid can produce certain displacement and be pressed on the sealing surface of outlet end, ensures outlet end sealing.Although the good seal performance of floating ball ball valve, but the load that spheroid bears working medium has all passed to exit seal circle, therefore the seal ring of outlet end undergos the work loads of medium, be only applicable to the small-bore environment of mesolow, and spheroid floats, and valve rod is fixing, then in opening process, because the axis of spheroid and valve rod exists departing from, this just causes extra operation moment of torsion, and operation moment of torsion is increased.
Model utility content
Problem to be solved in the utility model is the problem overcoming prior art, provide a kind of can be applicable to respective occasion, the ball valve of good sealing effect.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of intelligent breathing ball valve, comprise valve body, spheroid and handle, valve body comprises left valve barrel and right valve barrel, left valve barrel is fixedly connected with right valve barrel, also spheroid is provided with between described left valve barrel and right valve barrel, the surface of contact of described left valve barrel, right valve barrel and spheroid also comprises seal and serve as a contrast, described sealing lining is arranged on foam body, described foam body is fixedly connected with valve body, the top of described valve body is also fixing is provided with valve rod, and the top of described valve rod is also provided with the handle of valve rod.
Concrete, described left valve barrel and right valve barrel are also respectively arranged with the seal groove for arranging sealing block, the shape of described seal groove is the groove circumferentially arranged, and the sectional shape of seal groove is rectangle, and described foam body and seal groove match.
Concrete, described left valve barrel is also provided with valve body joint, and described valve body joint is also provided with valve rod hole, and described valve rod is arranged in valve rod hole, is also provided with filler in described valve rod hole, and described filler is fixed by Gland.
Concrete, the top of described valve rod is provided with hexagonal junction surface, and described hexagonal junction surface is also provided with handle.
The advantage that the utility model has and good effect are: a kind of intelligent breathing ball valve, can the sealing block of intelligent breathing by being replaced by by common seal ring.Sealing block is made up of PTFE sealing lining and PTFE cavernosa material compound.When ball valve closed condition, valve downstream pressure medium is relatively high.Medium infiltrates in foam body pore and foam body volume is swollen, and to increase the pressure of sealing surface, strengthens sealing effect.And reduce at valve opening state valve downstream pressure medium, the medium in press-in foam body pore can be squeezed out a part, makes foam body volume-diminished, thus alleviates the pressure of sealing surface.The moment of torsion of valve can be reduced like this, also can slow down the wearing and tearing of seal ring, and then extend valve working life.
Accompanying drawing explanation

In figure: 1 left valve barrel, 2 right valve barrels, 3 spheroids, 4 foam bodies 5 seal lining, 6 valve rods, 7 handles.
Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
A kind of intelligent breathing ball valve, comprises valve body, spheroid 3 and handle 7.Valve body also comprises left valve barrel 1 and right valve barrel 2, is also provided with valve body joint 1 time at left valve barrel, and valve body joint is the part for arranging spheroid 3, and spool 6 is sphere structures that a centre is provided with cylindrical hole.The junction surface of left valve barrel 1 and right valve barrel 2 is also provided with valve seals.Also be provided with valve rod 6 at the top of spheroid 3, what valve rod 6 was fixing is connected in spheroid 3, and valve rod 6 is arranged through the valve rod hole of valve body joint.In the valve rod hole of valve body joint, be also provided with back-up ring, back-up ring is used for valve rod to carry out radial location.In order to the radial location of proportioning valve rod aperture, the valve rod under back-up ring is also provided with baffle ring, baffle ring is identical with the diameter of valve rod hole.Between baffle ring and back-up ring, be also provided with valve stem packing ring, thus valve rod 6 and space outerpace are sealed.Meanwhile, also can there is moving radially of trace by between valve rod 6 and valve body joint, thus reduce the accuracy of manufacturing of spheroid 3, valve rod 6, valve body joint.Also be provided with filler between valve rod 6 on back-up ring and valve body joint, filler is also provided through the Gland of valve rod 6.Gland is used for fixing and sealing up filler, thus is lived by valve seal.Also be provided with a hexagonal part at the top of valve rod 6, hexagonal part is also provided with handle 7, thus actuate valve stem 6 is rotated.
Left valve barrel 1, right valve barrel 2 are also respectively arranged with seal groove, for arranging foam body 4 on seal groove, are also provided with the sealing contacted with spheroid 3 outside foam body 4 and serve as a contrast 5.When medium infiltrates in the pore of foam body 4, foam body 4 volume is swollen, to increase the pressure of sealing surface, strengthen sealing effect.And valve downstream pressure medium reduces when valve opening, the medium in the pore of press-in foam body 4 can be squeezed out a part, makes foam body 4 volume-diminished, thus alleviates the pressure of sealing surface.The moment of torsion of valve can be reduced like this, also can slow down the wearing and tearing of seal ring, and then extend valve working life.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
