Abstract
A stop valve comprises a valve body, a valve rod, a valve cover, a valve clack, a cap and a hand wheel. The valve body is provided with an inlet, an outlet and a valve port, wherein the inlet and the outlet are for medium circulation. The valve clack is installed at the lower end of the valve rod and arranged in a valve cavity of the valve body, and corresponds to the valve port. The stop valve further comprises a padding pressing plate, the padding pressing plate is connected with the valve cover through bolts, padding is distributed between the valve rod and the valve cover, and a padding pressing sleeve is arranged between the padding pressing plate and the padding. The upper portion of the valve body is connected with the lower portion of the valve cover in a sealing mode, the upper portion of the valve cover is connected with the cap in a sealing mode, an elastic gasket is arranged on a combined face of the valve body and the valve cover, the valve clack is in a shape with the middle portion wide and the two ends narrow, and a spiral water flowing channel is arranged in the valve cavity of the valve body. The stop valve has the advantages that the padding pressing sleeve is additionally arranged between the padding pressing plate and the padding, the padding pressing sleeve and the padding pressing plate form a double seal, and therefore sealing performance of the padding is further guaranteed.
Description
Technical field
The utility model relates to a kind of valve, especially relate to a kind of stop valve.
Background technique
Although existing stop valve can reach circulation or the cut-off of effective pilot line medium, the number of fitting parts of its whole product is many, reliability decrease.Simultaneously, because accessory is many, corresponding cost of material, purchase cost, assembly cost and administration expenses are also many, cause the Economy of whole product to descend; Again because the accessory of this stop valve is more, complicated structure, when stop valve slightly had damage, detachable maintaining bothered very much, generally can only integral replacing, the waste resource.In addition, existing stop valve is when sealing filler, and general adds the lid layer follower on filler, and its sealing is not high, after having used a period of time, situation about leaking easily occurs.
The model utility content
In order to solve above technical problem, the utility model provides a kind of and prevents that effectively filler from leaking, simple in structure, easy to assembly, material and assembly cost is low, detachable maintaining easily, the stop valve of more making rational use of resources.
in order to solve this technical problem, the utility model is taked following scheme: a kind of stop valve, comprise valve body, valve rod, valve gap, flap, cap and handwheel, described valve body is provided with the import of medium circulation, outlet and valve port, flap is loaded on the valve rod lower end and is placed in the valve body valve pocket, and corresponding with valve port, described stop valve also comprises hold-down grid, hold-down grid is connected with valve gap by bolt, filler distribution is between valve rod and valve gap, be provided with filler pressing sleeve between hold-down grid and filler, described valve body top and bonnet lower are tightly connected, valve gap top and cap are tightly connected, the junction plane of described valve body and valve gap is provided with resilient pad, flap is the narrow shapes in middle wide two ends, be provided with the pipelined channel of spiral in the valve body valve pocket.
Valve gap and cap are passed in described valve rod upper end, and with handwheel, are connected, and described handwheel is anchored on valve rod by hexagon nut.
The beneficial effects of the utility model: add a filler pressing sleeve between hold-down grid and filler, filler pressing sleeve and hold-down grid form dual fail-safe, and the sealing of filler further is protected.In addition, stop valve accessory of the present utility model is less, assembles simple and conveniently, has reduced workman's labor intensity, simultaneously also greatly reduce cost of production, simple in structure, detachable maintaining is simple and convenient, when stop valve slightly has damage, do not need integral replacing, can take easily maintenance apart.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
