Abstract
The invention provides a combined tee, which is used for quickly opening various metal pipes and nonmetal pipes with or without pressure and then installing branch pipes. The combined tee is composed of a rigid combined tee, a flexible sealing tape and a locking bolt, wherein, the rigid combined tee is made from steel, nodular cast iron, nylon and other materials and is composed of a semi-circular pipe clamp, a semi-circular pipe clamp with a bypass as well as a longitudinal displacement restraining part, wherein, if longitudinal displacement of the pipes does not need to be restrained, the longitudinal displacement restraining part can be not assembled; the inside sealing tape adopts an annular lip sealing mode; a sealing pad is arranged at the annular joint between the two semi-circular pipe clamps and is integrated with the inside sealing tape; and the combined tee is fastened by the locking bolt and a locking nut. The combined tee has the advantages of solving the problem that assembly can be carried out in the case of medium blockage under the operating condition of pipelines, being capable of quickly and directly assembling the combined tee on openings of the pipes, achieving good self-sealing property, realizing convenient bolt fastening mode and having lower requirements for construction environments.
Description
Technical field
The present invention relates to a kind of combination threeway, especially a kind of combination threeway that is used for various metal pipes, nonmetal pipeline band pressure or does not have pressure quick mounting shunt pipe.
Background technique
Reserve when tubing shunting Placement at present commonly used has pipe laying and install branch pipe welded directly to the run pipe behind threeway and the metallic conduit opening after threeway, the cutting additional.
Reserve threeway and have following problem: flow threeway caliber decision shunt pipe caliber in advance, be difficult to satisfy the requirement of shunt volume; Need arrhea installation; The bolt of required installation is more; The bolt hole that is connected is difficult to centering, the bolt penetration hole difficulty; It is fastening fully be difficult to by installing space restriction bolt, and it is fastening to be difficult to symmetry, influences the joint bearing capacity; Sealing gasket is easy to dislocation, and the tubing that is connected also is easy to dislocation, has strengthened the pressure loss of pipeline.
The cutting back is installed threeway and is had following problem: when pipe pressurized, need stop the pipe interior medium transport, break off main pipe; The tubing that is connected needs basic centering, and the two ends pipe shifted is difficult, has strengthened the pipeline construction difficulty
There is following problem in branch pipe welded directly to the run pipe behind the metallic conduit opening: when pipe pressurized, need cut pipeline and stop the pipe interior medium transport; Because tubing open cross-section size irregularity, welding difficulty; Weld is perishable, and is difficult to do preservative treatment.
Therefore, be necessary to invent and a kind ofly be used for that tubing is shunted fast, the combination threeway of bypass arm.
Summary of the invention
The object of the invention is to provide a kind of combination threeway that the quick shunting of pressure, bypass arm were pressed or do not had to the tubing band that is used for.
In order to achieve the above object, the present invention is made up of stiff assembly threeway, flexible sealing band, lock bolt.
Periphery of the present invention is that the inboard is the flexible sealing with material such as rubber with the stiff assembly threeway of material such as steel, spheroidal graphite cast iron, nylon.
The stiff assembly Three-way pipe hoop of periphery is made up of the semicircle pipe clamp and length travel attaching means three parts of semicircle pipe clamp, band bypass.The pipeline length travel need not retrain, and then can not assemble the length travel attaching means.
The inner seal band has adopted the ring-type lip seal.
Adopted sealing gasket at two halves pipe snap ring to the joint, and sealing pad and its inner seal band are connected as a single entity.
The bypass diameter can be selected according to engine request, or identical with straight-through diameter, or different.
The link that is assemblied on the bypass can be selected according to the arm connection request, or is flange or for flexible pipe clamp or for other connecting means.
The combination threeway is fastening through lock bolt and nut.
Compared with prior art, Operating Pressure of the present invention must not broken off main pipe and stopped medium transport, directly will make up threeway and be assemblied in shunting place of pipeline desire, has fast, advantages such as convenience, good sealing effect, saving installation time, raising effect.
Description of drawings
Fig. 1 is a transverse sectional view of the present invention;
Fig. 2 is a plan view shown in Figure 1.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is described further.
This combination threeway is made up of stiff assembly threeway 1, flexible sealing band 2, lock bolt 3, and wherein stiff assembly threeway 1 is made up of the semicircle pipe clamp 1.2 and length travel attaching means 1.3 3 parts of semicircle pipe clamp 1.1, band bypass.
The present invention divides band to press shunting and does not have the shunting of pressure.
Do not have to press shunting: with pipeline 4 openings, will make up threeway 1 and be installed in pipeline 4 openings, and make opening and bypass concentric in the same way in position that desire is installed arm; Assembling lock bolt 3 is also given fastening; Afterwards, the arm valve is installed, external arm had both been accomplished the nothing of pipeline and had been pressed shunting.
Band is pressed shunting: will make up threeway 1 and be installed in pipeline 4 desire shuntings place, and make by-pass port and desire divide flow path direction consistent; Mounted valve and pipe tapping machine on by-pass port utilize pipe tapping machine excision pipeline 4 tube walls; Lay down pipe tapping machine, external arm had both been accomplished the band of pipeline 4 and had been pressed shunting.
Need not retrain like the pipeline length travel, then can not assemble length travel attaching means 1.3.
Can select the bypass diameter according to engine request, or identical with straight-through diameter, or different.Can be assemblied on the bypass afterwards according to the selected link of arm connection request.
The length of combination threeway 1 increases with branch diameter; The quantity of clamping bolt 3 increases with the increase of combination threeway 1 length.
The present invention has following advantage;
One of characteristics of this combination threeway are fast, conveniently.Operating Pressure must not broken off main pipe and stopped medium transport; Do not have pressing operation directly will make up threeway is assemblied in the pipeline tapping place and gets final product.Lock bolt quantity is far fewer than flange, and bolton is convenient.Save the installation time greatly, improved work efficiency.
Two of the characteristics of this combination threeway are reliable.The flexible sealing band has adopted lip, has the selfsealings performance, and pressure is higher, sealability better, thereby improved the reliability of sealing greatly.
Three of the characteristics of this combination threeway are to require lower to construction environment.The builder's yard is much smaller than other open split methods; Do not need draining, drying, only need the no solid foreign materials in clearing of pipeline opening or pipe end surface to get final product, need not carry out other surface treatments.
This combination threeway using scope is wide, applicable to the fast opening shunting of various metal pipes, nonmetal pipeline.
