Abstract

The utility model discloses a flared connecting structure for pipes, which comprises two pipes, wherein each pipe comprises a straight pipe and a bell mouth, the bell mouths of the two pipes are in butt joint and are fixed through beveled flange plates sheathed on the outer walls of the bell mouths; the surface of each beveled flange plate, which is in contact with the pipe, comprises a cylindrical surface and a conical cylindrical surface; the diameter of a small circle of each conical cylindrical surface is equivalent to the diameter of each cylindrical surface, and the cylindrical surfaces and the conical cylindrical surfaces of the beveled flange plates are in sheathed joint and fixation with the parts of the straight pipes and the bell mouths of the pipes; a sealing gasket is arranged between the two bell mouths, a circle of upper bulge is arranged at the middle part of the outer wall of the sealing gasket, and the outer wall surface from the root part of the upper bulge to the outer edge of the sealing gasket is a slope with the height gradually reduced; and the end surfaces of the bell mouths are hermetically connected with two side surfaces of the upper bulge of the sealing gasket, and the outer wall slope of the sealing gasket is jointed with the inner walls of the bell mouths. The flared connecting structure for the pipes can effectively prevent the flange plates from shedding, the sealing performance is good and the connection is reliable.

Description

A kind of tubing enlarging linkage structure
Technical field
The utility model belongs to the pipeline connection technology field, relates in particular to a kind of tubing enlarging linkage structure.
Background technique
At present; the mining pipe of PVC adopts flanged joint to connect mostly; straight socket joint connects and R type socket joint connects; the mining pipe of PVC problems such as joint socket breaks, flanged joint comes off occur through regular meeting in bad working environment; cause phenomenon such as leak, breathe freely; it is unreliable to connect, and is seriously threatening the safety in production in colliery.
The model utility content
The purpose of this utility model provides the reliable tubing enlarging of a kind of connection linkage structure.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of tubing enlarging linkage structure, comprise two tubing of forming by straight tube and horn mouth, two tubing horn mouths dock and fix by the angle flange plate of horn mouth outer wall suit, angle flange plate and tubing surface of contact are made up of barrel surface and circular cone tube face and circular cone tube face axis of small circle equals the barrel surface diameter, and the barrel surface of angle flange plate and circular cone tube face are fixed with the straight tube and the horn section socket of tubing respectively; Be provided with seal washer between two horn mouths, seal washer outer wall middle part is provided with a circle and goes up projection, is reduce highly gradually domatic from epirelief root intermarginal outer wall to seal washer; Protruding bi-side are tightly connected on horn mouth end face and the seal washer, and the seal washer outer wall is domatic fits with the horn mouth inwall.
Described straight tube inwall is fixedly connected with the pipe pipe nipple, and pipe pipe nipple external diameter and straight tube internal diameter equate; Described seal washer inner diameter equates that with the straight tube internal diameter seal washer inwall middle part is provided with a circle lower convexity; Described seal washer is positioned at the cavity that pipe pipe nipple and horn mouth are surrounded, and pipe pipe nipple end face and lower convexity bi-side are tightly connected.
In the utility model, the barrel surface of angle flange plate and circular cone tube face are fixed with the straight tube and the horn section socket of tubing respectively, can prevent effectively that flange plate from coming off; Be provided with seal washer between two horn mouths, protruding bi-side are tightly connected on horn mouth end face and the seal washer, and the seal washer outer wall is domatic fits with the horn mouth inwall, and the seal washer special structure design has guaranteed good sealing property, connects reliable.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is a gasket structure schematic representation among Fig. 1.
Embodiment
As Fig. 1, shown in Figure 2, a kind of tubing enlarging linkage structure, comprise two tubing of forming by straight tube 1 and horn mouth 3, two tubing horn mouth 3 butt joints and fixing by the angle flange plate 2 of horn mouth 3 outer wall suits, angle flange plate 2 is made up of barrel surface and circular cone tube face with the tubing surface of contact and circular cone tube face axis of small circle equals the barrel surface diameter, the barrel surface of angle flange plate 2 and circular cone tube face are fixed with the straight tube 1 and the horn mouth 3 part sockets of tubing respectively, be provided with seal washer 4 between two horn mouths 3, seal washer 4 outer walls middle part is provided with a circle and goes up protruding 4-1, and going up protruding 4-1 root intermarginal outer wall to seal washer 4 certainly is reduce highly gradually domatic; The last protruding 4-1 bi-side of horn mouth 3 end faces and seal washer 4 are tightly connected, and seal washer 4 outer walls are domatic fits with horn mouth 3 inwalls.Described straight tube 1 inwall is fixedly connected with pipe pipe nipple 6, and pipe pipe nipple 6 external diameters and straight tube 1 internal diameter equate; Described seal washer 4 inner diameters equate that with straight tube 1 internal diameter seal washer 4 inwalls middle part is provided with a circle lower convexity 4-2; Described seal washer 4 is positioned at the cavity that pipe pipe nipple 6 and horn mouth 3 are surrounded, and pipe pipe nipple 6 end faces and lower convexity 4-2 bi-side are tightly connected.
When the utility model connects, be sleeved on angle flange plate 2 on the tubing in order, in straight tube 1, be stained with pipe pipe nipple 6, etc. bonding pipe pipe nipple 6 fixing after, end face is done smooth processing, and the last protruding 4-1 bi-side of loading onto 4, two horn mouth 3 end faces of seal washer and seal washer 4 between horn mouth 3 and pipe pipe nipple 6 are tightly connected, pipe pipe nipple 6 end faces and lower convexity 4-2 bi-side are tightly connected, and with bolt 5 two angle flange plate 2 are fixed at last and can be finished connection.
