Abstract

An automatic centering rapid fasting flange without screws is characterized in that the utility model tube comprises clips and tie-ins connected with ends of the tube; two ends of the clips are provided with lugs, screws are arranged on the lugs, the clips are wedged between the two relative tube tie-ins. The flange of the utility model changes the past manner connected by screws, when the two tubes with tie-ins are relative, the clips are wedged between the two tube tie-ins, which are fixedly connected by bolts. The utility model has compact structure, convenient installation, uniform force, perfect sealing, material saving, simply process, which can bear a higher pressure.

Description

Self-alignment does not have the fast connection orchid of screw

Technical field

The utility model belongs to a kind of pipeline connecting parts, is specially the flange with the pipe butt joint.

Background technique

Existing flange mostly is the bolt butt joint, has a plurality of bolts hole on the flange plate.After the two tubes butt joint, between flange by bolton.This kind structure is made complicated, the dismounting trouble, and because flange diameter is bigger, big with quantity of material.Because the fastening force of each bolt is difficult for consistent, often influence the leakproofness that flange connects.Also owing to be subjected to the restriction of bolt, sense of rotation arbitrarily during installation is made troubles to installation, and is when especially installing space is restricted, more outstanding.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of self-alignment does not have the fast connection orchid of screw, easy accessibility, and good airproof performance is processed easyly, and economical with materials can be born elevated pressures.

Self-alignment of the present utility model does not have the fast connection orchid of screw, it is characterized in that comprising:

The pipe joint that is connected with the pipe termination, and

Clamp, the clamp two ends have the ear seat, have screw on the ear seat, and clamp is stuck between two relative pipe joints.

Flange of the present utility model, changed and adopted the screw ways of connecting in the past, the band pipe joint two tubes relatively after, clamp is stuck in (fastening clamp between two pipe joints) between two pipe joints, shape according to pipe joint, select the quantity of clamp, so that the tight periphery of surrounding tube joint between clamp and clamp, it is fixedly connected to pass relative screw by bolt between clamp and clamp.Therefore, the thickness of the width of dehiscing of clamp after will be relative with two pipe joints adapts.This mode of structure is automatically entad realized pressure, makes the pipe joint periphery stressed evenly.

The cross section of clamp can be the groove shape, and pipe joint is stuck in the groove.

The utility model also is a pipeline connecting device, the shape of the similar existing screw jointing type flange of pipe joint.

In order to realize that pipeline more fast connects and operation easy, the pipe joint end is preferably disc, and clamp has two at least, preferably by two identical clamps (similar two semicircles) with discoidal pipe joint border seal.

The face that clamp is stuck in the pipe joint end is the inclined-plane, can bear higher pressure like this.

The material of pipe joint can be various suitable any materials, as steel, cast iron, composite material etc.

Advantage of the present utility model: make simply, easy accessibility can be realized the quick connection of pipeline.Owing to need not open screw on the pipe joint, the diameter of pipe joint can be littler than the flange plate of band screw, can save material like this.When pipeline connected, according to installation situation, two pipes can rotate in 360 degree scopes arbitrarily, are not subjected to any restriction, only need the fastening clamp during installation, get final product self-alignment, the bolt on the first-class clamp, and flange can be realized evenly fastening.Because the flange circumference is stressed evenly, has improved the sealing that pipeline is installed, and can bear high pressure pressure.Because flange size is little, bending moment is little, mechanical property is good.Below be the comparison of the utility model and same specification standard flange:

Description of drawings

Fig. 1 is a structural representation of the present utility model, also is the mounting structure schematic representation;

Fig. 2 is a right elevation for Fig. 1.

Among the figure: 5 bolts, the 6 ear seats of 1 clamp, 2 pipe joints, 3 sealing gaskets, 4 pipe joint ends

Embodiment

Fig. 1, Fig. 2 are example structure schematic representation of the present utility model, below in conjunction with embodiment's description of drawings:

Pipe joint 2 is welded on the pipe, pipe joint end 4 is a disc, during the two tubes butt joint, the pipe joint end is to flat, be added with sealing gasket 3 therebetween, the cross section of clamp (clamp is dehisced) is groove shape fastening two pipe joint ends, and the surface of contact of clamp and the fastening of pipe joint end is inclined-plane (groove is the inclined-plane).After two clamp fastenings, fixedly connected with bolt 5 between them up and down by the screw on the ear seat 6.So just, realized the butt joint between the two tubes.
