Abstract
The utility model relates to a connecting pipe fitting which comprises a connecting sleeve pipe, a sealing sleeve, and a sealing sleeve pipe. The utility model is characterized in that the end face of the connecting sleeve pipe is an inner conical inclined plane; the inner wall of one end of the sealing sleeve pipe is provided with an annular boss, the table top of the annular boss is a conical inclined plane which is opposite to the conical inclined plane, and the connecting sleeve pipe is sheathed in the sealing sleeve pipe; the sealing sleeve is arranged between the annular boss in the sealing sleeve pipe and the end face of the connecting sleeve pipe. The utility model has the characteristics of simple structure, convenient and rapid installation, favorable sealing performance, etc.
Description
The utility model relates to a kind of connection pipe fitting, a kind of connection pipe fitting of water specifically is installed, warm up, gas pipe line being used.
At present, the conventional method of tapping, mantle fiber is still adopted in the installation of most of plumbing pipes, and this method not only operation is many, complicated operation, the installation and maintenance inconvenience, and time-consuming, take a lot of work, installation quality can not guarantee that especially the local installation and maintenance at turning, dead angle are more inconvenient.Chinese patent 97245626 discloses a kind of pipe fitting joint of being made up of fittings body, cutting ferrule and seal washer, in fittings body, be provided with the spill inner chamber, cutting ferrule is divided into several lobes, lobe end outside projection, place in the fittings body spill inner chamber together with seal ring, every lobe inboard is provided with tooth, this structure more complicated, seal is bad, and installation is not very convenient.
The purpose of this utility model is to provide a kind of connection pipe fitting of simple in structure, quick and easy for installation, good leak tightness.
The purpose of this utility model is to realize by following proposal:
The utility model comprises adapter sleeve, stuffing box gland and Sealed casing pipe, and characteristics are that the end face of adapter sleeve is the inner cone inclined-plane; One end inwall of Sealed casing pipe is provided with ring-shaped lug, and the table top of ring-shaped lug also is the awl inclined-plane, and relative with the awl inclined-plane of adapter sleeve, and adapter sleeve is socketed in the Sealed casing pipe; Stuffing box gland is located between interior ring-shaped lug of Sealed casing pipe and the adapter sleeve end face.
The utility model has the advantages that:
(1) simple in structure, manufacture easily, and with low cost;
(2) quick and easy for installation, professional not strong, general personnel can finish installation exercise fast;
(3) good leak tightness generally can be born the pressure more than 6, is applicable to indoor water, warms up piping erection engineerings such as reaching coal gas.
Embodiment is described in detail below in conjunction with the utility model:
Fig. 1 is the utility model embodiment's a structural representation;
Fig. 2 is the A-A sectional view of the utility model embodiment's Sealed casing pipe.
See figures.1.and.2, the utility model comprises adapter sleeve 2, Sealed casing pipe 3 and stuffing box gland 4, and the both ends of the surface that it is characterized in that adapter sleeve 2 are the inner cone inclined-plane, and the two ends of adapter sleeve are provided with outside thread 21; The inwall of one end of Sealed casing pipe 3 is provided with ring-shaped lug 5, ring-shaped lug 5 table top also for the awl inclined-plane, and relative with the awl inclined-plane of adapter sleeve 2, stuffing box gland 4 is located in the Sealed casing pipe 3 between the ring-shaped lugs 5 and adapter sleeve 2 end faces; Be provided with internal thread 31 and match at the other end of Sealed casing pipe 3 with the outside thread 21 of adapter sleeve 2.
Its operating process is: connected pipe 1 and 11 is enclosed within Sealed casing pipe 3, the stuffing box gland 4 respectively and adapter sleeve 2 two ends successively, screwing hermetic sleeve pipe 3, stuffing box gland is under the awl ramp effect on Sealed casing pipe 3 and the adapter sleeve 2, produce stronger radial pressure, thereby play the effect of clamping and closed conduit 1 and 11.
For the ease of installing and maintenance, the pipe outer wall of adapter sleeve of the present utility model and Sealed casing pipe is provided with axisymmetric tool cutting edge plane 6.
In addition, adapter sleeve of the present utility model also can be connected in the Sealed casing pipe.
Adapter sleeve of the present utility model can be three-way pipe, four-way pipe or bend pipe etc.
Because of common rubber sealing boot is aging easily, therefore above-mentioned stuffing box gland can be wrapped on the connected tube outer wall and be formed by asbestos, flax silk or white glues band etc.
