Abstract
The utility model discloses a rubber diaphragm plate for a railway brake valve. A seal rib and the middle of the diaphragm plate are formed integrally; the seal rib forms an upward protrusion and a downward protrusion relative to the middle of the diaphragm plate; the end surface of the upward protrusion is in contact with a charging valve body; and the working area of the middle of the diaphragm plate is not in contact with the charging valve body. The rubber diaphragm plate has the advantages that the operation reliability of the inflation parts of the conventional 103 type lorry air distributor, the conventional 104 type passenger car air distributor and derivative products of the air distributors can be improved; the failure of the distributing valves caused by perforation, rupture and the like of the diaphragm plate are avoided; and the service life of the diaphragm plate is prolonged.
Description
Technical field
The utility model relates to the sealing member technical field, and particularly a kind of railway brake valve is used rubber diaphragm.
Background technology
The inflation lamina membranacea that is used for 103 type lorry air slide valves, 104 type passenger vehicle air slide valves at present is as shown in Figure 1; Integral body is the bowl-like type; Fig. 2 can be known by Fig. 1 and 2 that for the assembly drowing of existing inflating rubber lamina membranacea the inflating rubber lamina membranacea of existing structure adopts the mode of " encasing " inflation valve body to seal; Its sealing force action direction is for radially, and sealing band is a lamina membranacea muscle 5.Adopt this structure will make outside lamina membranacea area B 6 is exposed to, in carrying, assembling process, cause 6 damages of lamina membranacea area B owing to collide with easily like this; In addition, in the utilization process of distributing valve, lamina membranacea zone C 7 can be constantly in course of action and 3 frictions of inflation valve body, thereby produce abrasion, is prone to cause this zone to produce lamina membranacea perforation and breaks, and the distributing valve effect was lost efficacy.
The utility model content
The goal of the invention of the utility model is: to the problem of above-mentioned existence; A kind of charging portion function reliability that can improve existing 103 type lorry air slide valves, 104 type passenger vehicle air slide valves and derived product thereof is provided, and the railway brake valve that prolongs lamina membranacea service life is used rubber diaphragm.
The technical scheme of the utility model is achieved in that a kind of railway brake valve uses rubber diaphragm; Be shaped to one by sealed muscle and lamina membranacea centre portion; It is characterized in that: the said sealed muscle relatively junction of itself and lamina membranacea centre portion forms lower convexity; The end face of said raising contacts with the inflation valve body, and the work area of lamina membranacea centre portion does not contact with the inflation valve body.
The described railway brake valve of the utility model is used rubber diaphragm, and the linkage section of its said lamina membranacea centre portion and sealed muscle is bending upwards, and the lower convexity of said linkage section lower surface and sealed muscle partly forms groove.
The described railway brake valve of the utility model is used rubber diaphragm, and the end face of its said lower convexity flushes with the lower surface of lamina membranacea centre portion.
The utility model is through the moulding design to sealed muscle and lamina membranacea centre portion structure; The sealing force action direction is vertical by radially changing into, utilize the convex design of sealed muscle with respect to the lamina membranacea centre portion, the work area Hide All that makes the lamina membranacea centre portion is at the inflation valve inner; Damage has prevented to collide with; And the work area of lamina membranacea centre portion in the course of the work with the inflation valve body do not contact, stopped bad abrasion, simultaneously; The bending part of lamina membranacea centre portion and sealed muscle linkage section is in the groove that sealed muscle lower convexity and lamina membranacea form, and has effectively prevented in carrying, assembling process the phenomenon of colliding with to this part.The utility model can improve the charging portion function reliability of existing 103 type lorry air slide valves, 104 type passenger vehicle air slide valves and derived product thereof; Prevent the problem of the distributing valve effect inefficacy that causes, and prolonged the service life of lamina membranacea because lamina membranacea bore a hole, broken etc.
Description of drawings
Fig. 1 is the assembly drowing of existing inflating rubber lamina membranacea.
Fig. 2 is the structural representation of existing inflating rubber lamina membranacea.
Fig. 3 is the assembly drowing of the utility model rubber diaphragm.
Fig. 4 is the structural representation of the utility model.
Mark among the figure: 1 is sealed muscle, and 1a is the end face of raising, and 1b is the end face of lower convexity, and 2 is the lamina membranacea centre portion, and 2a is a linkage section, and 3 are the inflation valve body, and 4 is groove, and 5 is the lamina membranacea muscle, and 6 is the lamina membranacea area B, and 7 is the lamina membranacea zone C.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done detailed explanation.
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Shown in Fig. 3 and 4; A kind of railway brake valve is used rubber diaphragm; Be shaped to one by sealed muscle 1 and lamina membranacea centre portion 2; The junction of said sealed muscle 1 relative itself and lamina membranacea centre portion 2 forms lower convexity, and the end face 1a of said raising contact with inflation valve body 3, the work area of lamina membranacea centre portion 2 with inflate valve body 3 and do not contact; Said lamina membranacea centre portion 2 upwards bends with the linkage section 2a of sealed muscle 1, and the lower convexity of said linkage section 2a lower surface and sealed muscle 1 partly forms groove 4; The end face 1b of said lower convexity flushes with the lower surface of lamina membranacea centre portion 2.
Adopt the rubber diaphragm of said structure; The sealing force action direction is vertical by radially changing into, utilize the convex design of sealed muscle with respect to the lamina membranacea centre portion, the work area Hide All that makes the lamina membranacea centre portion is at the inflation valve inner; Damage has prevented to collide with; And the work area of lamina membranacea centre portion in the course of the work with the inflation valve body do not contact, stopped bad abrasion, simultaneously; The bending part of lamina membranacea centre portion and sealed muscle linkage section is in the groove that sealed muscle lower convexity and lamina membranacea form, and has effectively prevented in carrying, assembling process the phenomenon of colliding with to this part.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
