Abstract

The utility model relates to an improved connector of round pipes, which is composed of a sleeve pipe, two sealing rings and two glands, wherein the sleeve pipe is sheathed at the connecting ends of two pipes, and the sealing rings are arranged on the pipes at both ends of the sleeve pipe. The two annular glands provided with connecting holes are connected by screw bolts and nuts, and the glands fasten the sleeve pipe, the sealing rings and the two pipes together. The utility model has the advantages of no drill tapping, easy and quick installation and maintenance, good tightness, long service life, etc., so the utility model is suitable for all kinds of round pipes, such as galvanized pipes, plastic pipes and aluminum plastic laminated pipes, etc.

Description

The circular pipe connecting-refused machine
The utility model relates to water, gas circular pipe connecting-refused machine.
In prior art, being connected of water pipe and tracheae normal adopts two logical or threeways to realize.Yet when adopting two logical or threeways to connect, the termination of water pipe or tracheae must the tapping tapered thread, makes it logical with two or threeway is connected and could realizes the requirement of plugging into, and this makes troubles to installation and maintenance.And be easy to corrosion after the tubing tapping, influenced working life.In addition, honest the trying hard to recommend of country recommended use plastic tube and aluminium-plastic composite pipe replacement galvanized pipe at present, and the above-mentioned method of plugging into but can't adopt.
The purpose of this utility model is to provide a kind of improved circular pipe connecting-refused machine, and this connecting-refused machine be need not tapping to refuting the tubing that connects, and makes things convenient for I﹠M, but also is applicable to the connection of plastics and al-plastics composite pipe.
Task of the present utility model is achieved in that this connecting-refused machine is made up of sleeve pipe, seal ring and gland, casing pipe sleeve is connected to the connection of two tubing, respectively be provided with a seal ring on the tubing at sleeve pipe two ends, two annular glands that have attachment hole tighten together sleeve pipe, seal ring and two tubing with the screw bolt and nut connection.
The two ends of described sleeve pipe all have intilted chamfering.
Described gland partly is made up of with a conical ring that is connected with flat ring endoporus a flat loop section, and the endoporus of flat ring is slightly larger than the cover external diameter of pipe, and the internal diameter of conical ring osculum end is slightly larger than the external diameter of tubing, evenly has on outer shroud and is not less than 4 bolt hole.
During use, earlier with two tube end faces to connecting, and allow the connection of casing pipe sleeve to two pipe, on the tubing at sleeve pipe two ends, put seal ring, at last two glands are enclosed within on the sleeve pipe with screw bolt and nut it evenly to be tightened together and just can.After two glands tightened up, the inner conical surface at the chamfering of sleeve pipe and gland conical ring place just can produce axially and radial pressure seal ring, makes seal ring tightly encase two tubing, plays good seal action.This shows that this connecting-refused machine has tubing does not need tapping, I﹠M is easy, and is quick, advantages such as good airproof performance and long service life.Be all circular pipes, comprise galvanized pipe, the optimal accessory of plugging into of plastic tube and aluminium-plastic composite pipe.
Be further described below in conjunction with the structure of accompanying drawing the utility model embodiment.
Fig. 1 is the utility model one embodiment's a longitudinal sectional view.
Fig. 2 is another embodiment's of the utility model a longitudinal sectional view.
As shown in Figure 1, the utility model includes sleeve pipe 1, seal ring 2 and gland 3.Sleeve pipe 1 and gland 3 can be made with bronze, the casting precision casting of stainless steel and ball or machining.Have intilted chamfering 7 at the two ends of sleeve pipe 1.Gland 3 is processed together by flat loop section 8 and conical ring part 9 disjunctors.Sleeve pipe 1 is enclosed within the connection of two tubing 4, and its internal diameter is slightly larger than the external diameter of tubing 4.Successively put into seal ring 2 and gland 3 at the two ends of sleeve pipe 1, connect a sleeve pipe 1, seal ring 3 and two tubing 4 with bolt 5 and nut 6 at last and tighten together.
Be illustrated in figure 2 as threeway connector of the present utility model, its sleeve pipe 1 is the threeway shape, and is provided with flange plate 6 at its three connection mouth places, and has bolt hole, and all the other structures are similar substantially to the foregoing description.Be connected with 6 pairs of handy bolts and nuts of three flange plate respectively with three glands 3 during use and just can.
