Abstract

The utility model discloses an integrated pressure self-tightening type zero-leakage flange cut-off valve which comprises a flange-type valve body, a valve rod, a valve deck, a packing part and a hand wheel. The upper end of the valve rod is fixedly connected with the hand wheel. The lower end of the valve rod is fixedly connected with a valve clack. The packing part comprises packing, wherein a packing gland is arranged at the upper end of the packing, and a packing pressing plate is arranged at the upper end of the packing gland. A sealing gasket and a zero-leakage device ring are arranged at the connecting position of the lower end of the packing and the flange-type valve body. The flange-type valve body and the valve deck are of an integrated structure. The zero-leakage device ring is made of rubber. The flange-type valve body and the valve deck are made of cast steel and are of a one-step forming structure. The integrated pressure self-tightening type zero-leakage flange cut-off valve has the advantages that that the structure of the integrated pressure self-tightening type zero-leakage flange cut-off valve is simple; the zero-leakage device ring is arranged between the sealing gasket and the packing so that the sealing performance of the integrated pressure self-tightening type zero-leakage flange cut-off valve is greatly enhanced, and the service life of the integrated pressure self-tightening type zero-leakage flange cut-off valve is prolonged; and due to the fact that the flange-type valve body and the valve deck are of the integrated structure, production and machining can be conducted conveniently and quickly, efficiency is high, and cost is low.

Description

One pressure self tightening zero leakage Flange Globe Valves
Technical field
The utility model belongs to valve field, particularly a kind of one pressure self tightening zero leakage Flange Globe Valves.
Background technique
The conventional flange stop valve time has been grown between valve rod and the valve body and will produce the gap, and what have has additional stuffing box packing, but the too big words stuffing box packing in gap also can slowly from the gap, run off, cause valve seal poor at last, working life is short.
The model utility content
At the deficiencies in the prior art, the utility model provides a kind of one pressure self tightening zero leakage Flange Globe Valves.
To achieve these goals, technical solution adopted in the utility model is:
One pressure self tightening zero leakage Flange Globe Valves, comprise flange-type valve body, valve rod, valve gap, filler part and handwheel, the valve rod upper end is affixed with handwheel, the affixed flap in valve rod lower end, filler partly comprises filler, and the filler upper end is provided with Gland, and the Gland upper end is provided with hold-down grid, be provided with gasket seal and zero leakage device ring in filler lower end and flange-type valve body joint, described flange-type valve body and valve gap are integral structure.
Described zero leakage device ring is made for the rubber material.
Described flange-type valve body and valve gap are cast steel once-through structure.
The beneficial effects of the utility model: the utility model is simple in structure, being provided with the zero leakage device ring between gasket seal and filler strengthens the valve seal performance greatly, improve valve working life, flange-type valve body and the production and processing of valve gap integral structure is convenient, efficient is high, cost is low.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
One pressure self tightening zero leakage Flange Globe Valves as shown in Figure 1, comprise flange-type valve body 1, valve rod 2, valve gap 3, filler part and handwheel 4, valve rod 2 upper ends and handwheel 4 are affixed, the affixed flap 5 in valve rod 2 lower ends, filler partly comprises filler 6, and filler 6 upper ends are provided with Gland 7, and Gland 7 upper ends are provided with hold-down grid 8, be provided with gasket seal 9 and zero leakage device ring 10 in filler 6 lower ends and flange-type valve body 1 joint, described flange-type valve body 1 is integral structure with valve gap 3; Described zero leakage device ring 10 is made for the rubber material; Described flange-type valve body 1 is cast steel once-through structure with valve gap 3.
The utility model is simple in structure, is provided with zero leakage device ring 10 between gasket seal 9 and filler 6 the valve seal performance is strengthened greatly, improves valve working life, and flange-type valve body 1 is convenient with valve gap 3 integral structure production and processings, efficient is high, cost is low.
Be the utility model preferred forms more than, those skilled in the art's simple change and replacement all are within the protection domain of the present utility model in related domain.
