Abstract

The utility model discloses a high-pressure tube joint, comprising a tube joint body, a pressing nut, a tube sleeve, a flaring steel tube and a center device. The essential technique is that the center device is provided with a large and a small conical surfaces, the small conical surface is contacted with the hole inclined plane in the tube joint body, the large conical surface is contacted with the flaring of the flaring steel tube, and two O-shaped seal rings are arranged on the large and the small conical surfaces of the center device. The unique sealing form of adding the seal rings on the conical surfaces ensures the pressurization action of the tube joint. The nominal pressure can reach 350 kgf/cm+[2].

Description

The utility model relates to a kind of pipe joint, particularly a kind of withstand voltage higher high-pressure pipe connector.
At present pipe joint miscellaneous is arranged in the annex of hydraulic pipe line, but total structural type has three kinds, they are Welded fittings, Bite type fittings, flared fitting.Wherein Welded fitting is simple in structure, but when installing welding quality require high, and dress folding inconvenience; Though Bite type fittings has overcome the shortcoming of the difficult mounting or dismounting of welding type, is that its tube quality to adapted is had relatively high expectations, the accuracy of manufacturing of cutting ferrule requires also high, thereby making is also difficult, and dismounting all needs to change cutting ferrule at every turn; Flared fitting (as shown in Figure 1), because it has only the outer inclined-plane of enlarging steel pipe and union body to contact, so sealing effect is poor, it is withstand voltage also lower that (the highest nominal pressure only reaches 160kgf/cm 2), can only be used for, the low pressure oil-way system.
At above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of install and remove convenient and withstand voltage higher high-pressure pipe connector.
The purpose of this utility model is to realize like this, the pipe box that it comprises union body and makes the gland nut that is threaded with this union body and be pressed on the enlarging steel pipe and can move with gland nut, its technological points is also to comprise that one has big, the center fixture of the little conical surface and two " O " shape O-ring seals, center fixture is installed between the enlarging of union body inward hole slope and enlarging steel pipe, the little conical surface of center fixture contacts with the pipe joint inward hole slope, the big conical surface of center fixture contacts with the enlarging of enlarging steel pipe, and it is big that two " O " shape O-ring seals are installed in center fixture respectively, in the fixed groove that is had on the little conical surface.Rotatably compress nut and just drive pipe box, the enlarging steel pipe is pressed on the big conical surface of center fixture firmly, promote center fixture simultaneously, its little conical surface is pressed on the inward hole slope of union body.
The utility model is owing to increased center fixture and two O-ring seals that are installed on the large and small conical surface that have the large and small conical surface than prior art, the seal form of this uniqueness, having guaranteed the withstand voltage effect of pipe joint, is 350kgf/cm through testing nominal pressure of the present utility model 2
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing thereof:
Fig. 1 is a flared fitting
Fig. 2 is the utility model structural representation
With reference to figure 2, an embodiment of the present utility model, it is by union body 1, and gland nut 4, pipe box 6, enlarging steel pipe 7, center fixture 2, two " O " shape O-ring seals 3,5 are formed.Center fixture 2 has the large and small conical surface and through-core hole, its big conical surface contacts with the enlarging of enlarging steel pipe 7, the little conical surface contacts with union body 1 inward hole slope, the through-core hole internal diameter is identical with the union body internal diameter, also have the fixed groove that " O " shape O-ring seal can be installed on the large and small conical surface of center fixture, two " O " shape O-ring seals 3,5 just are installed in these two fixed grooves, pipe box 6 is pressed on the enlarging steel pipe 7 and with the rotation of gland nut 4 and moves, and union body 1 endoporus two ends are the inclined-plane.During use, rotatably compressing nut 4 just drives pipe box 6 and moves, drive center fixture 2 by enlarging steel pipe 7, the large and small conical surface of center fixture 2 is contacted firmly with the enlarging of enlarging steel pipe 7 and the inward hole slope of union body 1 respectively, add " O " shape O-ring seal 3,5 that is installed on the large and small conical surface, make sealing effect better, withstand voltage increasing.
The utility model both can have been made above-mentioned straight-through high-pressure pipe connector, also can make the high-pressure pipe connector of right angle, threeway, damped type, diaphragm type.

Claims (2)

1, a kind of high-pressure pipe connector, the pipe box that it comprises union body and makes the gland nut that is threaded with this union body and be pressed on the enlarging steel pipe and can move with gland nut, it is characterized in that also further comprising that one has big, the center fixture of the little conical surface and two " O " shape O-ring seals, center fixture is installed between the enlarging of union body inward hole slope and enlarging steel pipe, center fixture is big, the conelet face contacts with the enlarging and the union body inward hole slope of enlarging steel pipe respectively, and it is big that two " O " shape O-ring seals are installed in center fixture respectively, in the fixed groove that is had on the little conical surface.
2,, it is characterized in that described pipe joint head body endoporus two ends are the inclined-plane according to the described high-pressure pipe connector of claim 1.
