Abstract
The invention relates to an expanding type two-way hard sealed spherical valve which comprises two hemispheres, a wedge body, a valve body, a valve cover, a valve rod, a supporting shaft, a roller, a positioner and the like, wherein the two hemispheres form a combined sphere; a positioning shaft is arranged at the lower end of the combined sphere, the supporting shaft is arranged in the middle of the sphere body of the combined sphere, and the supporting shaft is in a round shape; a Z-shaped groove is arranged at the middle part of the valve rod, the roller is fixed in the ''Z''-shaped groove to be used for the positioning of the lifting and rotation of the valve rod, the wedge body in the shape of a gate plate is arranged at the connecting part of the lower end of the valve rod and the upper end of the valve body, and the sphere body is combined together through the positioner; the valve rod is connected with the wedge body for connecting the sphere body and is installed in an inclination angle of 10-16 degrees, so that the sphere body can not be closely expanded; and an expanded ball clack is tightly stuck on the valve seat for sealing to form a hard-to-hard two-way seal on the valve seat. The upper sealed structure achieves zero leakage, and the structure capable of regulating flow achieves cleaning and sealing functions. The invention saves resources and cost and has convenient installation and use.
Description
Technical field:
The present invention relates to a kind of pipeline control valve door, particularly the lower end of combination ball has the spheroid centre of positioning shaft, combination ball to be provided with fulcrum, makes spheroid strut, close up nimbly and freely, saves the major advantage of the energy.
Background technique:
At present, the ball valve of soft seal valve seat obtains bigger promoting the use of in engineering.But soft seal valve seats such as teflon, rubber and nylon are not suitable for high temperature media, and are not suitable for the fire-proof valve, so limited the using scope of ball valve.Improve ball valve reliability and technical parameter, increase the service life, adopting metal-seated is the inexorable trend of ball valve development.
Pull problem in order to alleviate between the ball valve metal-seated, existing metallic elastic valve seat, metal floating valve seat and elasticity add ball valve sealing structures such as floating valve seat.Though these structures can improve the technical parameter of ball valve, and alleviate the problem of pulling, problem such as occur in easy to wear, high temperature deformation, the spring groove slagging scorification, ball valve between the metal-seated again and valve seat is easily stuck, can rise dead under the high temperature and the life-span is short.The ball valve of existing " bracing type sealing configuration ", because compages existing problems, close up when beginning to rotate at spheroid, tend to pull valve seat sealing surface suitable for reading, making up in the middle of the ball easily coking, slagging scorification simultaneously directly influences spheroid and closes up, and the worst hot case spheroid is opened, and closes up dumb, it is dead to rise easily, so be difficult to promote
Summary of the invention:
Existing hard seal ball valve exists not enough, the invention provides a kind of expanding type two-way hard sealed spherical valve of pipeline control valve door, is made up of two hemisphere, wedge, valve body, valve gap, valve rod, fulcrum, roller and positioning work pieces etc., and two hemispheres become the combination ball.
The technical solution adopted for the present invention to solve the technical problems is: the lower end of combination ball is provided with positioning shaft, is provided with fulcrum, fulcrum circle shape in the middle of the spheroid of combination ball; The valve rod middle part is provided with " Z " type groove, and roller is fixed in " Z " type groove, is used for the orientation usefulness that valve rod promotes and rotates, and the joint of the lower end of valve rod and valve body upper end is the wedge of flashboard shape, by positioning work piece spheroid is combined; Valve rod is connected with spheroid with wedge and connects, and 10～16 ° of gradients are installed, and spheroid can not risen extremely; Be adjacent to valve base sealing with strutting ball clack, valve seat is formed firmly to hard two way sealed.Last seal construction is accomplished zero leakage
The invention has the beneficial effects as follows: all-pass footpath, to save the energy, do not flowed to restriction, two way sealed, nothing wear and tear, zero leakage economizes on resources and cost, makes things convenient for user installation and use, long service life.

Embodiment
A kind of expanding type two-way hard sealed spherical valve, form by two hemisphere, wedge, fulcrum, roller and positioning work pieces, two hemispheres become the combination ball, the lower end of combination ball is provided with positioning shaft, be provided with fulcrum (3) in the middle of the spheroid of combination ball, fulcrum (3) adopts the circle design, makes spheroid (4) strut, close up nimbly and freely, even under the operating mode of easily fouling, slagging scorification, do not influence strutting, closing up of spheroid (4) yet; Valve rod (6) middle part has roller (5), be fixed in " Z " type groove, be used for the orientation usefulness that valve rod (6) promotes and rotates, the joint of the lower end of valve rod (6) and valve body (6) upper end is the wedge (7) of flashboard shape, by positioning work piece (8) ball (4) body is combined; When being rotated counterclockwise handwheel, valve rod (6) lifting, positioning work piece (8) will make up ball and close up, and valve rod (6) drives spheroid (4) is not simultaneously having half-twist under the prerequisite of friction with the valve seat disengaging, and ball valve is opened.Otherwise when turning clockwise handwheel, valve rod (6) drives combination ball half-twist, valve rod (6) continues when descending, and wedge (7) will make up ball and strut to valve inlet/outlet two ends, and parallel moving presses to valve seat, reach two way sealed, valve closing, and close tight more more; Be adjacent to valve base sealing with strutting ball clack, valve seat adopts the body technique for overlaying, forms firmly hard two way sealed is sealed, and is limited the advantage of installing with the arbitrary position but do not flow to, and does not have scratch, weares and teares, and is not afraid of to attach granule medium on the sealing surface.When the combination ball rotarily opened valve, ball clack and valve base chamber were gapped, are not rotating under the contact condition, so more there are not wearing and tearing.Use the rising stem (RS.) method for opening and closing, it is little to make ball valve operate moment of torsion, and uses and go up design of Sealing Structure, and reach zero and reveal, the space that the while forms with valve seat in spheroid (4) rotary course, the can regulate flow reaches the cleaning seal action; Valve rod (6) is connected with spheroid (4) with wedge (7) and connects, and installs with 10～16 gradients, make at low temperatures close, Open valve can not rise extremely because of spheroid (4) high temperature expands yet during high temperature.Adopt flashboard shape wedge (7) support to hold together ball clack simultaneously, not only reliable, good rigidly, and have and close tight more function more, and it can provide the tightening seal of the tight power of mechanical wedge-type to guarantee to continue, and also can obtain the life-span compensation behind sealing surface wear.
