Description
Technical field
The utility model relates to a kind of ball valve, specifically the hard sealing and fixing type ball valve of a kind of anti-solid particle.
Background technique
The repid cut-off valve that hard seal ball valve is applicable to high temperature, high pressure and contains the media such as solid particulate matter, slurry, fiber, polymer, valve seat and the centre of sphere, through special superpressed processing, can be widely used in the industries such as petrochemical industry, high pressure coal gasification, plastic polymer, vapour system, mining industry, metallurgy, chemical fibre.Valve is when containing the environmental work of solid powder particle, and the moment of torsion of valve can be multiplied, and must consider intensity and the moment of torsion of valve rod, prevents that load is excessive, and valve rod torsional deformation causes valve switch not in place.And solid particle can enter the damage that causes sealing surface between ball and the sealing surface of seat.Powder particle gets in preloading spring storehouse, the valve seat back side, can cause the inefficacy of spring, when serious, there will be ball core and valve seat locking or valve seat to fit with spool.
Model utility content
For solving the problems of the technologies described above, the utility model provides a kind of hard sealing and fixing type ball valve of anti-solid particle that can use under the rugged environment that contain particle, powder.
The technical solution adopted in the utility model is:
The hard sealing and fixing type ball valve of a kind of anti-solid particle, comprise main valve body, valve rod, ball core, auxiliary valve body, in the cavity of described main valve body, there is a ball core, ball core is placed on the ball core supporting base in main valve body cavity, the top of described main valve body is provided with and is fixedly connected with is bonnet, in bonnet, there is a central passage, described valve rod is connected by taking off post with ball core through the central passage of bonnet and the upper wall of main valve body, described auxiliary valve body is arranged on the side of main valve body, auxiliary valve body is fixed by double-screw bolt and nut and main valve body, between described main valve body and auxiliary valve body, be provided with wound gasket, it is characterized in that: described ball core and master, between auxiliary valve body, be provided with valve seat, the sealing surface position, front and back of described valve seat is all provided with scraper cutting edge, between described valve seat and ball core, be provided with dust-proof belt, described valve seat and master, between auxiliary valve body, be provided with seal ring, isolating ring, dish spring and valve seat trim ring.
In space between described valve rod and bonnet, be provided with successively matrix liner, filler, Gland, hold-down grid from bottom to top, described hold-down grid is provided with dish spring, described dish spring is provided with dish spring cover outward, dish spring is provided with dish spring gland, described dish spring gland is fixed on bonnet by dish spring pull bar and nut, between described nut and dish spring pull bar, is provided with pad.
A plurality of regular breach of Milling Process on the dish spring supporting surface of described valve body.
Described valve rod adopts high-strength stainless steel material.
In the runner of described main valve body and auxiliary valve body, be provided with pottery body neck bush.
The beneficial effects of the utility model are:
Valve rod of the present utility model adopts the high material of intensity to prevent that the moment of torsion of valve from increasing, and causes valve rod load excessive, and valve rod torsional deformation causes valve switch not in place.Sealing surface position before and after valve seat all increases " scraper cutting edge " design, and in valve opening or the process of closing, valve seat blade can play the effect of striking off to ball adsorption thing, make solid particle can with goal with sealing surface between cause the damage of sealing surface.Between valve body and valve seat, use dish spring, and on dish spring supporting surface a plurality of regular breach of Milling Process, can prevent that powder particle from getting in preloading spring storehouse, the valve seat back side, cause spring failure, or occur that ball core and valve seat locking or valve seat cannot occur with the situation of spool laminating.
