Abstract
The invention provides a fixing ball valve which comprises a spring, fastening screws, a valve seat, a valve seat gasket, an upper bearing, a valve rod, a sealing ring, a ball body, a valve body and a lower bearing. The spring is arranged on one side of the section of the valve body. The valve seat is arranged on one side of the spring and fixedly arranged on the valve seat gasket. The fastening screws are fixedly arranged at one end of the valve body and embedded in the valve body. The ball body is arranged in the valve body and the sealing ring is arranged on the surface of one end of the ball body. The sealing ring is tightly connected with the upper bearing and the valve rod is fixedly arranged at one end of the upper bearing. The fixing ball valve is compact in structure and suitable for long transport pipelines and common industrial pipelines; the strength, the safety, the severe environment resistance and the like of the ball valve are specially considered in design, so that the ball valve is suitable for various corrosive and non-corrosive media; labor is saved in the operation process, the ball body is supported through the upper bearing and the lower bearing, friction is reduced, and therefore the too large torque caused by the huge sealing load generated due to the fact that the ball body and a sealing seat are pushed through inlet pressure is eliminated.
Description
Technical field
The present invention relates to a kind of ball valve, particularly a kind of fixing ball valve.
Background technique
Along with world's new energy are widely used, domestic also at continuous development & application, as cryogenic medias such as LNG Liquefied natural gas, liquid ethylene, liquid oxygen, along with these new energy demands grow with each passing day, ball valve is as oil, chemical industry, the industry pipelines such as rock gas cut off the capital equipment of medium, and ultra-low temperature ball valve is immediately also by wilderness demand.Fixing ball valve is high-performance ball valve of new generation, is applicable to long-distance transport pipes and general industry pipeline, and its intensity, Security, adverse environment resistant etc. have carried out special consideration when designing, and are applicable to various corrosivity and non-aggressive medium.It is compared with floating ball valve, during work, the active force that before valve, hydrodynamic pressure produces on spheroid all passes to bearing, spheroid can not be made to move to valve seat, thus valve seat can not bear excessive pressure, so the torque of fixing ball valve is little, valve seat distortion is little, sealability is stable, long service life, is applicable to high pressure, heavy caliber occasion.
Heavy caliber fixing ball valve pivot structure mainly in the market: spool spheroid relies on valve rod location, namely valve rod is directly inserted in the top of spool spheroid, spool spheroid relies on valve rod location, but, the fixing ball valve of said structure is in switching process, and valve rod not only needs to bear twisting stress, also will bear the pressure of runner inner fluid medium, thus have impact on the working life of valve rod, also can produce harmful effect to the sealing of valve body simultaneously; And when fixing ball valve is arranged under the environment of some vibrations, easily slight rigid collision is there is between its spool spheroid and valve seat, if things go on like this, rigid collision will be worn and torn the sealing surface of spheroid and valve seat, the sealability of fixing ball valve is caused to decline, and spool spheroid also has an impact to valve rod while vibration, therefore still there is the space of improvement.
Summary of the invention
The technical problem to be solved in the present invention overcomes existing defect, provides a kind of fixing ball valve, conveniently can work, increase work efficiency, and effectively can solve the problem in background technique.
In order to solve the problems of the technologies described above, the invention provides following technological scheme:
A kind of fixing ball valve of the present invention, comprise spring, fastening screw, valve seat, valve washer, upper bearing (metal), valve rod, seal ring, spheroid, valve body and lower bearing, side, described valve body cross section is provided with spring, described spring side is provided with valve seat and described valve seat is fixedly installed on valve washer, described valve body one end is fixed with fastening screw and described fastening screw embeds valve inner, described valve inner is provided with spheroid and described spheroid end surface is provided with seal ring, described seal ring compact siro spinning technology upper bearing (metal) and described upper bearing (metal) one end is fixedly installed valve rod.
Further, described upper bearing (metal) is cylindrical structural and described upper bearing (metal) runs through seal ring is connected with spheroid.
Further, described spheroid bottom is fixedly connected with lower bearing.
Further, the multiple position of described valve body is fixedly connected with by fastening screw.
Further, described upper bearing (metal) runs through ball interior and is connected with lower bearing.
The beneficial effect that compared with prior art the present invention reaches is:
Compact structure of the present invention, be applicable to long-distance transport pipes and general industry pipeline, its intensity, Security, adverse environment resistant etc. have carried out special consideration when designing, be applicable to various corrosivity and non-aggressive medium, rapid operation, spheroid is supported by metal (upper, reduces friction, eliminates the huge sealing load because inlet pressure promotion spheroid and sealing seat are formed and causes excessive moment of torsion.
