Abstract

The utility model pertains to an accessory of liquid pipeline, which aims to overcome the problems of traditional pipeline connecting method such as complicated operation, the bad work condition and low reliability about connecting quality. The utility model consists of a middle body, a sealing ring and a locking cover. The locking cover is provided with a slide ring. The middle body is a pipe-shaped unit, and outside of which has an even number polygon used for tightening. Inner of the two ends have tapered hole and outside have the screw thread. The sealing ring has a pipe-shaped unit. The outside of one end of the sealing ring has the tapered degree which matches with the middle body. Pressing by the locking cover, the sealing ring can form very high leak tightness. The utility model has the advantages of increasing efficiency, reducing cost, improving working condition and assuring high project quality.

Description

Novel pipe sealing link

The utility model belongs to a kind of annex that fluid line is used, and it is specifically related to a kind of structure of novel pipe sealing link.

Development along with industrial technology, being used for conveyance fluid is that the pipework of water, oil, gas is more and more, the attended operation of pipeline is the link of individual trouble, and small-bore pipe connects through pipe fitting commonly used, and the method for the pipeline welding commonly used of bigbore pipe or conveying high-pressure liquid connects.Must be on the surface of pipe end when connecting with pipe fitting machining screw, machining screw then is the extremely operation of difficulty on bigbore pipe.It is also pretty troublesome go up to connect pipe at the construction field (site) with the method for welding, must dig the technology hole when connecting the last interface of under ground piping, and it is also very inconvenient in the overhead welding operation at place, foot position to come to this.In a word, the problem of using traditional connecting means to exist is: 1. troublesome poeration, workload is big and labor intensity is high; 2. some concrete processing must be carried out at the construction field (site), bring the deuce to pay to field work: 3. inefficiency and be not easy to guarantee that the position dimension of construction quality, especially pipeline does not reach very high requirement; 4. be subjected to the working life that influences pipe joint of environmental conditions lower, appearance is leaked also to be needed to repair repeatedly, and influence can cause very big loss to production greatly under the situation of left alone without help worker's operation concerning major works or large enterprise.

The purpose of this utility model is to propose a kind of novel pipe sealing link, realizes the reliable connection of pipe way, and with the connecting means of standardized link replacement pipe fitting or welding, it has the advantages that to raise the efficiency, reduce cost, improve working conditions.

By as above design, the feature of the novel pipe sealing link that this programme provided is: it by intermediate, seal ring, and tightening cover formed, its intermediate is a tubular member, its internal diameter and connected tube outer diameter adapt, and have the conical surface in the inside at two-port place and the outside is threaded; Its seal ring is that a tubular member internal diameter matches with the external diameter of connected pipe, and the appearance of its end is the conical surface, and its tapering matches with the inner cone of intermediate; The internal thread of tightening cover matches with outside thread on the intermediate, and the interior edge face of tightening cover is pressed on the end face of seal ring.

In this programme, be provided with slip ring between tightening cover and the seal ring, it is the structure of an air ring.There is the annular protrusion of a confinement tube interpolation degree of depth at the middle part of pipe in intermediate, is provided with the even number polygonal with the fastened tools adapted in the centre of outer surface.Its intermediate can be straight also can bending.The endoporus of its intermediate can be the step hole of a reducing, and a confinement tube interpolation degree of depth annular protrusion is also arranged at the interior edge face place of aperture.Its intermediate can also make the structural type of threeway or four-way.

Adopt this programme can embody following superiority: 1. to use the standard piece of this programme to connect pipe, can remove screw thread processing to pipe head, also without pricker oil, fiber crops or poly-tetrafluoro belt, as long as the pipe termination neatly just can be used, connection to the heavy caliber pipe can be welded, can reduce the operation of a lot of troubles, improve working condition; 2. the seal ring in this programme adopts nylon material, with tightening cover seal ring is compressed between intermediate and pipe and can form very reliably sealing, between tightening cover and seal ring, be provided with slip ring, can also avoid in installation, scratching seal ring, further improve the q﹠r of sealing part; 3. because this link simple in structure, pipe length is controlled easily, can accomplish strict position dimension requirement in wiring; 4. all standardization of each part of this scheme can realize that large-scale production can reduce manufacture cost, avoid operation when pipeline is installed to save and have reduced engineering cost man-hour, have improved efficient; 5. the pipe connection of this programme can make various ways, and the various links as gap bridge, threeway, four-way, elbow and reduction nipple can make all size on the size, so it is a product form of very superior seriation.

Fig. 2 is the structural representation of elbow link.

Fig. 3 is the structural representation of reduction nipple.

Fig. 4 is the structural representation of three-way union.

The embodiment of existing accompanying drawings this programme.This novel pipe sealing link is made up of intermediate 1, seal ring 2, tightening cover 3.Its intermediate is tubular member, and its internal diameter and connected pipe 8 external diameters adapt, and at the middle part of endoporus one annular protrusion are arranged, can confinement tube the inside degree of depth of insertion, there is taper hole the inside, two ends of intermediate and there is screw thread the outside; Seal ring also is a tubular member, and its internal diameter matches with the external diameter of connected pipe, and an outside end has tapering, and its angle matches with the inner cone of intermediate; Tightening cover is a nut of lid shape, its internal thread matches with the outside thread of intermediate, also be provided with a slip ring 4 at its interior edge face place, by slip ring strength is passed to seal ring when tightening tightening cover, in the time of can avoiding tightening it be scratched, also can avoid occurring between seal ring and the tightening cover abnormal mounting point relation.The intermediate of this link can make straight, also can make the form of elbow 5, also is provided with the annular protrusion of only inserting in the inside of two ends awl mouth when making elbow.It is step hole 6 that this intermediate can also make endoporus, forms the pipe joint of a reducing, at the interior edge face place of aperture annular protrusion is arranged also.In addition, intermediate can also make the form of threeway 7 or four-way.Except making different structures, it can make the Dimensions of various actual demand, so it is a product type spectrum of very superior seriation.Its superior part is that it can remove some loaded down with trivial details and difficult operations of job site from.It can be saved man-hour, reduce manufacture cost, improves working conditions and improve the sealing reliability of connection, is a very reliable form through evidence, is subjected to operator's welcome.
