Abstract
The utility model relates to an air pressure pipeline sealing and connecting device. The device is characterized by comprising two pipe joints which are fixed at the ends of two air pressure pipes respectively, wherein a convex platform is fixed on a butt-joint surface of one pipe joint, and a concave platform corresponding to the convex platform is arranged on a butt-joint surface of the other pipe joint; a circle of sealing groove is formed on the butt-joint surfaces of the two pipe joints on the same circumference respectively; a circle of sealing ring is embedded in the two sealing grooves; moreover, a flange is sleeved on the outer circles of the two pipe joints respectively; the two flanges are connected together through a fixing member; the convex platform is inserted into the concave platform; and the butt-joint surfaces of the two pipe joints are combined to extrude the sealing ring together to finish the connection and sealing of the two air pressure pipes. The air pressure pipeline sealing and connecting device provided by the utility model can be widely used for sealing and connecting the air pressure pipelines of various railway vehicles.
Description
Technical field
The utility model relates to a kind of line seal connection set, particularly about a kind of pneumatic circuit seal connection that is used for railway vehicle.
Background technique
At present, the seal connection that is used for pneumatic circuit on the China railways vehicle mainly adopts the form of two pipe joint planes to pressing.Wherein, have only a pipe joint to be provided with seal groove, the seal groove embedded seal ring, between seal ring and seal groove in no gap, do not have a rib outward.Two pipe joints are fixedly connected through two flanges and are integral.There is following defective in this seal connection: because the interface of two pipe joints is the plane, and pneumatic circuit not straight in the time of therefore can't proofreading and correct assembling and the joint gas leak phenomenon that causes; Because the end of a pipe joint does not have seal groove, gas circuit can directly be led to the outside; Seal groove on another pipe joint does not have rib outward, can't support the seal ring in it, and no gap in seal ring and the seal groove causes air pressure directly to act on seal ring.The air-tightness of whole device is unstable, and pipeline is not straight during assembling, and reasons such as the distortion of car body or vibration all can cause the pressurized gas of pneumatic circuit joint to leak, and influence the transportation safety of railway vehicle.
Summary of the invention
To the problems referred to above, the purpose of the utility model provides and a kind ofly can effectively ensure the bubble-tight seal connection of pneumatic circuit.
For realizing above-mentioned purpose, the utility model is taked following technological scheme: a kind of pneumatic circuit seal connection is characterized in that: it comprises two pipe joints that are fixedly installed on two pneumatic tube terminations respectively; Wherein, fixedly install boss on the interface of a pipe joint, corresponding with boss, on the interface of another pipe joint concave station is set; Respectively offer a circle seal groove in same circumference place on the interface of two pipe joints, two seal grooves are embedded in a circle seal ring; In addition, each sheathed flange on the two pipe joint cylindricals; Two flanges link into an integrated entity through fixed block, boss and then be inserted in the concave station, and the interface of two pipe joints combines, the co-extrusion seal ring.
Above-mentioned two pipe joints are welded on the termination of two said pneumatic tubes respectively.
Above-mentioned boss is on the one-body molded interface that is produced on said pipe joint.
Above-mentioned boss is an annular boss, and concave station is a ring-type concave station.
Above-mentioned seal ring is one to have the seal ring of self-sealing function.
The utility model is owing to take above technological scheme; It has the following advantages: 1, because the utility model adopts two pipe joints that have the concave, convex platform to cooperatively interact; Form the gas circuit labyrinth; Gas circuit is no longer directly led to the outside, therefore can reduce the not straight joint gas leak phenomenon that causes because of pipeline effectively.2, owing to all offer seal groove on two pipe joints that the utility model adopts; Imbed a seal ring in two seal grooves; Seal groove seals support to the seal ring in it, has therefore strengthened the seal action of seal ring, thereby has strengthened the stability of gas seal performance effectively.3, because the utility model adopts the seal ring of self-sealing function, and air pressure is big more, sealing function is strong more, thereby has strengthened the gas seal performance effectively.The utility model can be widely used in being tightly connected of different kinds of railways vehicle pneumatic circuit.

Embodiment
Butt joint accompanying drawing and embodiment carry out detailed description to the utility model below.
Like Fig. 1, shown in Figure 2, the utility model comprises two pipe joints 2 that are fixedly installed on two pneumatic tube 1 terminations respectively.Wherein, the interface of a pipe joint 21 is provided with boss 3, and is corresponding with boss 3, and the interface of another pipe joint 22 is provided with a concave station 4.Respectively offer in same circumference place on the interface of two pipe joints 2 a circle seal ring 6 is set in circle seal groove 5, two seal grooves 5.In addition, each a sheathed flange 7, two flange 7 links into an integrated entity through fixed block on the cylindrical of two pipe joints 2; Thereby annular boss 3 is inserted in the ring-type concave station 4; The interface of two pipe joints 2 combines, and co-extrusion seal ring 6 is accomplished the connection and the sealing of two pneumatic tubes 1.
In the foregoing description, two pipe joints 2 can be welded on the termination of two pneumatic tubes 1 respectively.
In the foregoing description, boss 3 can with pipe joint 21 integral production moulding.
In the foregoing description, boss 3 can be an annular boss, and concave station 4 can be a ring-type concave station.
In the foregoing description, seal ring 6 can for one the circle have self-sealing function seal ring.
The foregoing description only is used to explain the utility model; Wherein the shape of parts, Placement etc. can change to some extent; Every equivalents of on the basis of the utility model technological scheme, carrying out and improvement all should not got rid of outside the protection domain of the utility model.
