Abstract
The utility model discloses a flexible machinery mouthpiece composite rubber sealing ring, which is characterized in that the sealing ring is a ring shape structure formed by compressing the rubber materials with different rigidities. The rubber material with high rigidity makes a ring shape bracket and the rubber material enclosure layer with low rigidity is compositely pressed outside the ring shape bracket. The utility model has the advantages that 1, the acting force and counter acting force generated from the high rigidity ring shape bracket and a pipeline supporting ring ensure that the sealed surface made of low rigidity rubber material for the rubber ring keeps under excellent working statuses and also improves the compact strength of a joint; 2, the responding rebounded force coefficient is small when the pressure of the ring shape bracket part is under temperature changes and the position change of the joint; in addition, the joint has long-term sealed and stability. 3, the ring shape bracket keeps even gaps of the joint and even pressure of the rubber ring, avoids concentric pressure and prolongs the application lifetime of the rubber ring.
Description
(1) technical field:
The utility model relates to a kind of town gas conveyance conduit seal ring, particularly a kind of flexible mechanical interface combined type rubber seal.
(2) background technique:
At present, China's town gas conveyance conduit mainly adopts flexible mechanical interface ductile iron pipe or gray iron cast iron tube, interface adopts seal with elastometic washer, the jointing cushion rubber is in long-term stressed working state, be subjected to external force such as dynamic load, temperature variation to influence problems such as easy generation stress relaxation, coefficient of restitution is big, when stress is concentrated and integrated condition when being fit to the leakproofness and the working life that tend to reduce cushion rubber.
(3) summary of the invention:
The purpose of this utility model is to design a kind of flexible mechanical interface combined type rubber seal, and it can overcome the shortcoming of above-mentioned sealed interface, improves the sealing and the working life of interface.
The technical solution of the utility model: a kind of flexible mechanical interface combined type rubber seal, it is characterized in that it is the loop configuration that the rubber material by two kinds of different hardness is compositely suppressed to form, the rubber material of high hardness is made ring support, and the rubber material embracing layer compound suppressing of low hardness is in the ring support outside.
The outer had the support shape of position-limiting action for receiving waist shape, " worker " word shape or other top in its cross section of ring support that above-mentioned said high durometer rubber material is made can be made into.
Using method of the present utility model is: with above-mentioned flexible mechanical interface combined type rubber seal two tubes is coupled together, interface compresses the rubber seal support portions by differential, external force makes the soft rubber position be compressed distortion by support, has guaranteed the desired sealing effect of pipeline.
Superiority of the present utility model is: 1, high hardness ring support and pipeline bracing ring produce active force and reaction force, have guaranteed that the low-hardness rubber material sealing surface of cushion rubber is in the works fine state, have improved the leakproofness of interface; 2, the ring support position stressed under difference variation and during the interface displacement stress coefficient of restitution little, can keep the long-term tight stability of interface; 3, it is even that ring support keeps the joint socket gap, causes cushion rubber stressed evenly, prevents that stress is concentrated, the working life of having improved cushion rubber.
(4) description of drawings:
Accompanying drawing 1 is the plan view of the related a kind of flexible mechanical interface combined type rubber seal of the utility model.
Accompanying drawing 2 is the A-A cross-sectional view of accompanying drawing 1.
Accompanying drawing 3 is the local structure for amplifying schematic representation of accompanying drawing 2.
Accompanying drawing 4 is the user mode schematic representation of the related a kind of flexible mechanical interface combined type rubber seal of the utility model.
Wherein: 1 makes ring support for the rubber material of high hardness, and 2 is the rubber material embracing layer of low hardness, and 3 is socket, and 4 is bellmouth, and 5 is bracing ring, and 6 is differential, and 7 is flexible mechanical interface combined type rubber seal.
(5) embodiment:
Embodiment 1: a kind of flexible mechanical interface combined type rubber seal (seeing Fig. 1-4), it is characterized in that it is the loop configuration that the rubber material by two kinds of different hardness is compositely suppressed to form, the rubber material of high hardness is made ring support 1, and rubber material embracing layer 2 compound suppressings of low hardness are in the ring support outside.
The outer was for receiving waist shape (see figure 3) in ring support 1 its cross section that above-mentioned said high durometer rubber material is made can be made into.
Claims (2)
1, a kind of flexible mechanical interface combined type rubber seal, it is characterized in that it is the loop configuration that the rubber material by two kinds of different hardness is compositely suppressed to form, the rubber material of high hardness is made ring support, and the rubber material embracing layer compound suppressing of low hardness is in the ring support outside.
2, by the said a kind of flexible mechanical interface combined type rubber seal of claim 1, it is characterized in that its cross section of ring support that said high durometer rubber material is made can be made in the outer have the support shape of position-limiting action for receiving waist shape, " worker " word shape or other top.
