Abstract
The utility model discloses the technical proposal of an active no-screw pipe joint which is composed of a joint body, sealing components and a press cover, wherein, the joint body is a circular pipe, and outer screws are arranged at the two end ports which are tapered. The sealing components are tapered pipes which are arranged in the two end ports of the joint body. The press cover is a reducer pipe of which the inner wall is in a round table shape, and inner screws matched with the outer screws on the joint body are arranged in the end ports. The utility model has the advantages that the active no-screw pipe joint can conveniently, rapidly and reliably connect pipelines under the conditions that connected pipelines are not disassembled, threaded, etc.; during construction, labor intensity is low, and construction cost is low.
Description
The utility model belongs to a kind of pipe joint, and specifically, it relates to a kind of structure of not having the active pipe joint of screw thread.
At present, the Placement of various pipes (as water pipe, heating pipe, gas pipe etc.) mostly adopts fittings body, is being connected two mouth of pipe overcoat system outside threads, will be connected two pipes with the tubular configured joint body that has internal thread then and connect as one.The main deficiency of this fittings body is: need dismantle, overlap system screw thread etc. to connected pipeline; During construction, labor intensity is big and cost is high, and particularly to the maintenance of old pipeline, inconvenience more seems.
The purpose of this utility model provides the active pipe joint of a kind of no screw thread, and it does not need connected pipe is carried out any processing, pipeline can be connected; Need not dismantle connected pipe, be particularly suitable for maintenance old pipeline.
The purpose of this utility model is achieved in that the utility model mainly comprises fittings body 1, Sealing 2 and gland 3.Fittings body is that pipe, two-port place have outside thread, and two-port is tapered; Sealing is a conical pipe, is loaded in the fittings body two-port; Gland is the reducer pipe that inwall is frustoconic shape, and the internal thread that cooperates with outside thread on the fittings body port is arranged in the big port of internal diameter.
During use, the utility model is placed on threadless two connecting tubes 4, tightens gland and get final product.
Owing to adopted technique scheme, major advantage of the present utility model is: can be under the condition that connected pipe is not dismantled, mantle fiber etc. handled, and convenient, quick connecting tube reliably; During construction, labor intensity is low, and construction cost is low.
The drawing of the utility model accompanying drawing is described as follows:
Fig. 1 is a structural representation of the present utility model.
The utility model is described in further detail below in conjunction with drawings and Examples.Fig. 1 is the utility model embodiment's a structural representation, in an embodiment, is lined with ring washer 5 between Sealing and the gland.
Sealing of the present utility model is the conical pipe of nonmetallic material.Sealing is selected rubber or plastic materials for use.
Claims (3)
1, the active pipe joint of a kind of no screw thread has a fittings body, and it is characterized in that: it also comprises Sealing and gland; The head body is a pipe, and there is outside thread at the two-port place, and two-port is tapered; Sealing is a conical pipe, is loaded in the fittings body two-port; Gland is the reducer pipe that inwall is frustoconic shape, and the internal thread that cooperates with outside thread on the fittings body port is arranged in the big port of internal diameter.
2, according to the active pipe joint of the described no screw thread of claim 1, it is characterized in that: between Sealing and gland, be lined with rounded washers.
3, according to claim 1 or the active pipe joint of 2 described no screw threads, it is characterized in that Sealing can be the conical pipe of nonmetallic material.
