Abstract
The utility model provides a there is axle sleeve to prevent valve of impurity immersed structure, includes valve body, valve shaft, axle sleeve and valve plate, the valve shaft be located valve body central line department, the valve body top makes the valve shaft fix in the middle of the valve body through the installation gland, the valve body inner circle is hugged closely has seal face of the valve body, the valve body bottom is fixed the tail -hood on the valve body through the bolt, axle sleeve symmetric distribution and cover at the upper and lower both ends of valve shaft, install the sealing washer between top axle sleeve and the gland, it has O type sealing washer to fill up between bottom axle sleeve and the tail -hood, shaft seal circle, gasket and spring that the end of intaking of valve shaft and axle sleeve set gradually, the valve plate pass through the trundle and fix in valve shaft department in the middle of. The utility model discloses a set up spring and axle sealing ring structure, after existing wearing and tearing are irised out in the shaft seal, enclose automatic compensation through the elastic reaction power messenger shaft seal of spring, effectively prevent diping of impurity, guaranteed the sealed of valve shaft and axle sleeve, prolonged the life of valve.
Description
Technical field
The utility model belongs to valve processing technique field, particularly relates to a kind of valve having the anti-impurity immersed structure of axle sleeve.
Background technique
Valve is one of indispensable equipment on industrial pipeline, is usually used in blocking, regulating ducted flowing medium.The ducted medium had contains partial impurities (as silt etc.), for common butterfly valve structure, when the medium containing impurity in pipeline enters between valve shaft and axle sleeve, in the process that valve shaft rotates, will be rotated between valve shaft and axle sleeve friction, cause axle sleeve inner ring to wear and tear, cause valve to damage.
Summary of the invention
The utility model, for overcoming the problems referred to above, provides a kind of valve having the anti-impurity immersed structure of axle sleeve.
Technical solution adopted in the utility model is:
A kind of valve having the anti-impurity immersed structure of axle sleeve, comprise valve body, valve shaft, axle sleeve and valve plate, described valve shaft is positioned at valve body centerline, body top makes valve shaft be fixed in the middle of valve body by installing gland, valve body inner ring is glued with valve seals, and tail-hood is fixed on valve body by bolt by body base; Described axle sleeve is symmetrical and be enclosed within the two ends up and down of valve shaft, is provided with seal ring, is lined with O RunddichtringO between bottom axle sleeve and tail-hood between top axle sleeve and gland, Simmer ring, pad and spring that the feed-water end of valve shaft and axle sleeve sets gradually; Described valve plate is fixed on the middle of valve shaft by driving pin.
Described Simmer ring is that a kind of bottom can dilatancy, the structure that middle part is curved.
The beneficial effects of the utility model: the utility model is by arranging pad, spring and Simmer ring at the feed-water end of valve shaft and axle sleeve, when forming sealing after Simmer ring distortion, after there are wearing and tearing in Simmer ring, Simmer ring auto-compensation is made by the elastic acting force of spring, effectively prevent the immersion of impurity, ensure that the sealing of valve shaft and axle sleeve, extend the working life of valve.

Embodiment
A kind of valve having the anti-impurity immersed structure of axle sleeve, comprise valve body 1, valve shaft 2, axle sleeve 8 and valve plate 4, described valve shaft 2 is positioned at valve body 1 centerline, valve body 1 top makes valve shaft 2 be fixed in the middle of valve body 1 by installing gland 13, valve body 1 inner ring is glued with valve seals 3, is fixed on valve body 1 bottom valve body 1 by bolt by tail-hood 6; Described axle sleeve 8 is symmetrical and be enclosed within the two ends up and down of valve shaft 2, seal ring 12 is installed between top axle sleeve 8 and gland 13, O RunddichtringO 7 is lined with, the Simmer ring 9 that valve shaft 2 sets gradually with the feed-water end of axle sleeve 8, pad 10 and spring 11 between bottom axle sleeve 8 and tail-hood 6; Described valve plate 4 is fixed on the centre of valve shaft 2 by driving pin 5.
Described Simmer ring 9 is that a kind of bottom can dilatancy, the structure that middle part is curved.
Specific implementation process of the present utility model is as follows: valve in use, medium containing impurity in pipeline to be formed with middle part arc by the distortion of the lower expansion of Simmer ring 9 and seals, ensure that the foreign material in medium can not enter in the middle of valve shaft 2 and axle sleeve 8, when Simmer ring 9 has wearing and tearing, can make Simmer ring 9 can auto-compensation by the spring force of spring 11, again form seal pressure, ensure that valve shaft 2 and the sealing of axle sleeve 8, extend the working life of valve.
