Abstract
The utility model relates to a hemisphere valve structure sealed firmly, spraying one deck tungsten carbide layer I on the spheroid sphere, the sealed face of disk seat go up spraying one deck tungsten carbide layer II, and the intracavity of valve body is placed in to the spheroid, and the valve rod passes the valve body and places spheroidal splined hole internal fixation in, and it is downthehole that disk seat, carbon seal ring, sealing washer clamping ring, belleville spring place the latus rectum of valve body in proper order in, and with the fastening of disk seat gland, in valve body lower part guiding hole was packed into to the subassembly that leads, packing assembly packed into in the fill opening of valve body upper portion. The effect is: designed hemisphere valve structure sealed firmly, the disk seat can float left or right under spheroid and belleville spring's effect to rely on the spring force to compress tightly disk seat and spheroid, the adverse effect that has avoided machining error to bring makes a sealed some scope widen, thereby has reduced the requirement to the machining precision in can carrying high leakproofness. At spheroid sphere and valve seat seal face spraying tungsten carbide material, the wear -resisting of material and high temperature resistance ability have been improved.
Description
Technical field
The utility model relates to a kind of ball valve, particularly the hard seal semi ball valve structure of one, for industries such as steel industry, Aluminum, paper pulp, Coal Chemical Industry, oil.
Background technique
At present, on market, existing hard seal semi ball valve is fixed valve base structure, and difficulty of processing is large, and poor sealing performance, cannot meet more and more higher usage requirement.If spheroid and sealing surface of seat, without special processing, easily occur inordinate wear, sealability and working life is caused sharply to decline.The occasion that means suitable sealability is higher can only use the semispherical valve of soft sealing structure, and the problem such as sealing pair serious wear easily appears in soft sealing structure in actual use, and working life is shorter, and can not the operating modes such as High Temperature High Pressure be used for.
Summary of the invention
In view of prior art Problems existing, while the problems such as the utility model provides a kind of hard seal semi ball valve structure, easy to wear in solution, the life-span is short, realize higher sealability.
The utility model for achieving the above object, the technological scheme adopted is: a kind of hard seal semi ball valve structure, comprise: valve rod, valve body, valve seat, spheroid, valve seat gland, guidance set, filler assembly, it is characterized in that: also comprise carbon seal ring, seal ring pressure ring, belleville spring, described spheroid sphere sprays one deck carbide layers I, the sealing surface of described valve seat sprays one deck carbide layers II, described spheroid is placed in the lumen of valve body, valve rod is placed in the splined hole internal fixtion of spheroid through valve body, described valve seat, carbon seal ring, seal ring pressure ring, belleville spring is placed in the passing hole of valve body successively, fastening with valve seat gland, guidance set loads in valve body lower portion pilot hole, filler assembly loads in the stuffing hole of valve body top.
The beneficial effects of the utility model are: devise hard seal semi ball valve structure, valve seat can float to the left or to the right under the effect of spheroid and belleville spring, and rely on spring force valve seat and spheroid to be compressed, avoid the adverse effect that machining error is brought, seal point scope is broadened, thus reduce the requirement to machining accuracy while improving sealability.
At spheroid sphere and sealing surface of seat sprayed wc material, improve the wear-resisting of material and resistance to high temperature, thus reduce sealing pair wearing and tearing, improve working life and the sealability of valve.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the partial enlarged drawing of Figure 1A.
Embodiment
Below in conjunction with accompanying drawing, the utility model is explained in further detail.
As shown in Figure 1, 2, a kind of hard seal semi ball valve structure, comprise: valve rod 1, valve body 2, valve seat 3, spheroid 7, valve seat gland 8, guidance set 9, filler assembly 10, also comprise carbon seal ring 4, seal ring pressure ring 5, belleville spring 6, spheroid 7 sprays one deck carbide layers I7-1, the sealing surface of valve seat 3 sprays one deck carbide layers II3-1.
Spheroid 7 is placed in the lumen of valve body 2, valve rod 1 is placed in the splined hole internal fixtion of spheroid 7 through valve body 2, valve seat 3, carbon seal ring 4, seal ring pressure ring 5, belleville spring 6 are placed in the passing hole of valve body 2 successively, fastening with valve seat gland 8, guidance set 9 loads in the pilot hole of valve body 2 bottom, and filler assembly 10 loads in the stuffing hole of valve body 2 top.
Valve rod 1 drives spheroid 7 to rotate, when spheroid 7 sphere contacts with the sealing surface of valve seat 3, the sealing surface of spheroid 7 sphere and valve seat 3 constitutes the sealing configuration of carbide layers I7-1 and carbide layers II3-1, thus decreases sealing pair wearing and tearing, improves working life and the sealability of valve.
