Abstract
The utility model discloses a multi-level sealing stop valve and relates to the technical field of valves. A valve cover is fixed at the upper end of the valve body, a support is arranged at the upper end of the valve cover, a valve seat is arranged in the valve body, a valve clack is arranged on the valve seat, a valve clack cover is fixed at the upper end of the valve clack, a sealing ring is arranged between the valve clack and the valve clack cover, the lower end of the valve rod is connected with the valve clack through the valve clack cover, the upper end of the valve rod is connected with a hand wheel through a valve rod nut, a single direction thrust ball bearing is arranged on the outside of the valve rod nut, an oil cup is connected with one side of the single direction thrust ball bearing, and a bearing pressing cover is arranged at the upper end of the single direction thrust ball bearing. The multi-level sealing stop valve is simple in structure, safe and reliable, flexible to open and close, labor-saving in operation and good in sealing performance, has a dual-effect sealing function achieved by a metal sealing structure and a non-metal sealing structure and can guarantee that leakage is avoided after the valve is opened for ten thousand times. If the valve is used for a long time, the valve body is not required to be detached from a pipeline. After a medium is not used, the valve cover is detached, packing is changed, and the valve can be reused.
Description
Technical field:
The utility model relates to a kind of multi-level sealed stop valve, belongs to valve technology field.
Background technique:
Stop valve refers to the valve that closure member (flap) moves along the valve seat center line.According to this mobile form of flap, the variation of valve seat port is and flap stroke relation in direct ratio.Because the valve rod of such valve is opened or shutoff stroke is shorter relatively, and have and cut off function very reliably, again because the variation of valve seat port and the stroke relation in direct ratio of flap are very suitable for the adjusting to flow.Therefore, such valve is suitable as cut-out or adjusting and throttling use very much.
Present conventional stop valve structure more complicated, open and close dumb, troublesome poeration; Main, existing stop valve sealability is bad, is easy to generate leakage, has influenced the stability of system's operation greatly.
The model utility content:
At the problems referred to above, the technical problems to be solved in the utility model provide a kind of simple in structure, open and close flexibly, the multi-level sealed stop valve of good seal performance.
Multi-level sealed stop valve of the present utility model, it comprises valve body, valve seat, flap, seal ring, the flap lid, valve rod, valve gap, support, Stem Mut, single direction thrust ball bearing, lubricating cup, bearing gland and handwheel, fixedly there is valve gap the upper end of valve body by double-screw bolt and nut, the upper end of valve gap is provided with support, be provided with valve seat in the valve body, flap is arranged on the valve seat, fixedly there is the flap lid upper end at flap by the outer-hexagonal screw, and between flap and flap lid, be provided with seal ring, the lower end of valve rod is connected with flap by the flap lid, the upper end of valve rod is connected with handwheel by Stem Mut, the arranged outside of Stem Mut has single direction thrust ball bearing, and a side of single direction thrust ball bearing is connected with lubricating cup, and the upper end of single direction thrust ball bearing is provided with bearing gland.
The beneficial effects of the utility model: it can overcome the drawback of prior art, and is simple in structure, safe and reliable, open and close flexible especially, rapid operation, good seal performance, have the economic benefits and social benefits sealing function that metal sealing and nonmetal multi-layer sealing structure are formed, can guarantee to open ne-leakage ten thousand times; If long-time the use, valve body need not to separate pipeline, stops to unload behind the medium bottom flange and can change filler and reuse.
Description of drawings:
In order to be easy to explanation, the utility model is done to describe in detail by following concrete enforcement and accompanying drawing.
