Abstract
The utility model discloses a pneumatic valve sealing ring comprising an outer ring and an inner ring. The outer ring is connected with one end of the inner ring. A groove in the shape of an inverted taper is formed between the outer ring and the inner ring with a small opening and a large chamber and is filled with filler. The filler is in interference fit with the groove. Height of the filler is smaller than that of the groove. A steel plate is inserted between the inner ring and the groove. A lining of the groove of the pneumatic valve is filled with filler to expand the outer ring of the sealing ring so as to prolong service life of the sealing ring. The groove is of an inverted taper shape and has the small opening and the large chamber. The filler is in the interference fit with the groove and free of being extruded out of the groove. The pneumatic valve sealing ring is reliable in performance, handy and durable.
Description
Technical field
The invention belongs to pneumatic valve technical field, be specifically related to a kind of pneumatic valve seal ring.
Background technique
In some factories, the seal ring of pneumatic valve will wear and tear with 1 year, malfunctioning, the method of general maintenance is changed seal ring exactly, but some seal ring surface seems or is good, can change be waste at this point really, and buys seal ring and spend again, think that way allows the seal ring life-saving be that administrative staff and maintenance man think dry thing.
Summary of the invention
For addressing the above problem, the invention discloses a kind of pneumatic valve seal ring, at pneumatic valve groove liner filler, make seal ring outer ring support large, extend seal ring working life.
For achieving the above object, technological scheme of the present invention is as follows:
A kind of pneumatic valve seal ring, it is characterized in that: comprise outer ring and inner ring, described outer ring and inner ring one end link together, between outer ring and inner ring, be provided with inverted cone groove, the little the inside of import is large, is provided with packing in groove, described packing and groove interference fit, packing is no more than the height of groove, between inner ring and groove, is embedded with steel plate.
As a modification of the present invention, described channel bottom is circular arc.
As a modification of the present invention, described packing is rubber ring.
As a modification of the present invention, described packing is cotton thread.
As a modification of the present invention, described steel plate is 0.6mm galvanized steel plain sheet.
As a modification of the present invention, the tapering of described groove is 1:10.
As a modification of the present invention, described outer ring and inner ring are contour.
As a modification of the present invention, described packing size is than the thick 0.1-0.3mm of groove.
The invention has the beneficial effects as follows:
A kind of pneumatic valve seal ring of the present invention, at pneumatic valve groove liner filler, makes seal ring outer ring support large, extends seal ring working life, groove is inverted cone, and the little the inside of import is large, packing and groove interference fit, guarantee packing can outwards not extruded landing, and reliable performance, facilitates durable.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is sectional view of the present invention.
Reference numerals list:
1, outer ring, 2, packing, 3, inner ring, 4, steel plate, 5, groove.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, should understand following embodiment and only be not used in and limit the scope of the invention for the present invention is described.It should be noted that, word 'fornt', 'back', " left side ", " right side ", "up" and "down" that use is described below refer to the direction in accompanying drawing, and word " interior " and " outward " refer to respectively the direction towards or away from specific features geometrical center.
As shown in the figure, a kind of pneumatic valve seal ring of the present invention, comprises outer ring 1 and inner ring 3, described outer ring 1 links together with inner ring 3 one end, described outer ring 1 is contour with inner ring 3, between outer ring 1 and inner ring 3, is provided with inverted cone groove 5, and the little the inside of import is large, in groove 5, be provided with packing 2, described packing 2 and groove 5 interference fit, packing 2 is no more than the height of groove 5, between inner ring 3 and groove 5, is embedded with steel plate 4, described steel plate 4 is 0.6mm galvanized steel plain sheet, has some strength.
When work, in groove 5, fill out rubber ring, described rubber ring has the tapering identical with groove 5, described rubber ring size is than the thick 0.3mm of groove 5, due to the elasticity of rubber, rubber ring is pressed in groove 5, and owing to being embedded with steel plate 4 between inner ring 3 and groove 5, inner ring can not be out of shape, outer ring is stretched, seal ring can use again, cost-saving, also can be at the interior wadding line of groove 5, cotton thread is to a certain degree indeformable, long service life, is used the present invention can make the seal ring having worn and torn re-use one-year age, has greatly reduced the replacing number of times of seal ring.
The present invention arranges described groove 5 bottoms to be circular arc, in the time of seal ring support large deformation, can decompose strength, can not be ruptured in outer ring 1 and the connecting part of inner ring 3, distortion.
In order to ensure that packing can outwards not extrude landing, through many experiments, the tapering of described groove 5 is set to 1:10 best results, can either ensure that outer ring support is large, again can be because reaction force is extruded packing.
The disclosed technological means of the present invention program is not limited only to the disclosed technological means of above-mentioned mode of execution, also comprises the technological scheme being made up of above technical characteristics combination in any.
