Abstract
The utility model relates to an integrated type valve-deck-less through shut-off valve which comprises a valve body, a valve clack, a valve rod, a hand wheel, a sealing piece and a mounting piece. The lower end of the valve rod is fixedly connected with the valve clack. The upper end of the valve rod is connected with the hand wheel through a valve rod nut. The valve body is mainly in an integrated structure. A valve body middle cavity is fixedly provided with an upper sealing seat. Sealing padding is arranged between the valve rod and the valve body. An inner hole of the upper sealing seat and a valve rod outer circle are matched through a spline. The number of leakage points of valve deck connecting is reduced, abrasion by radial shaking on the middle cavity sealing padding when the valve rod moves is lowered, and the integrated type valve-deck-less through shut-off valve has the advantages of being good in sealing performance, long in product service life and the like.
Description
Technical field
The utility model relates to valve field, particularly about a kind of stop valve.
Background technique
Stop valve is comprised of valve body, flap, valve rod, valve gap, support, driving mechanism usually, valve body is fixedly connected with by bolt seal with valve gap, it is vertical with valve rod axis that valve body is imported and exported axis, valve rod one end is fixedly connected with flap, the other end is connected with driving mechanism by the Stem Mut on the support, support is provided with the valve rod rotation-preventing mechanism, prevents the valve rod rotation.Its major defect is that valve clack sealing surface is washed away greatly by medium, valve rod is by Stem Mut place one end location, and valve rod easy generation in moving up and down process is radially rocked, and the centering cavity seal packing produces wearing and tearing, affect simultaneously the precision that is sealed and matched of flap and valve seat, affect sealability and product working life.
Summary of the invention
The purpose of this utility model is the shortcoming that exists for prior art, provides a kind of flap to be subjected to medium to wash away little, valve rod and radially rocks the integral type of little, good seal performance, long product lifecycle without the valve gap through shut off valve in moving process.
The technical solution of the utility model comprises valve body, flap, valve rod, handwheel, Sealing and assembling set, the valve rod lower end is fixedly connected with flap, the valve rod upper end is connected with handwheel by Stem Mut, mainly be that valve body is the integral type structure, valve body lumen fixed installation upper seal support, stuffing box packing is arranged between valve rod and the valve body, adopts spline to cooperatively interact between the endoporus of upper seal support and the valve rod cylindrical.
In above technological scheme, valve body import and outlet axis are in the same horizontal line.
In above technological scheme, flap is fixedly connected with by steel pin with valve rod.
The utility model has the advantages that valve body adopts integrative-structure, reduced the leakage point that valve gap connects; Stuffing box packing is arranged between valve rod and the valve body, fixed installation upper seal support in cavity seal packing lower end in the valve body, valve rod is played location and anti-rotation effect, reduce and radially to rock the centering cavity seal packing when valve rod moves and produce wearing and tearing, raising sealability and product working life.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Integral type as shown in Figure 1 is without the valve gap through shut off valve, comprise valve body 1, flap 2, valve rod 4, handwheel 8, Sealing and assembling set, valve rod 4 lower ends are fixedly connected with flap 2, valve rod 4 upper ends are connected with handwheel 8 by Stem Mut 7, valve body 1 is the integral type structure, by forging molding, valve body 1 lumen fixed installation upper seal support 5, stuffing box packing 6 is arranged between valve rod 4 and the valve body 1, adopt spline to cooperatively interact between the endoporus of upper seal support 5 and valve rod 4 cylindricals, both valve rod 4 was had positioning action, again valve rod 4 is had the anti-rotation leading role, reduce the wearing and tearing of centering cavity seal packing 6 in valve rod 4 moving process, improve sealability.
Valve body 1 import and outlet axis have effectively reduced the flow resistance of medium in the same horizontal line, have reduced noise.Flap 2 is fixedly connected with by steel pin 3 with valve rod 4.
