Description

Combined type rapid pipe joint

Technical field:

The utility model is relevant with joint, and is relevant with the combined type rapid pipe joint that is applicable to various plastic pipes connections especially.

Background technique:

At present, the pipe connector (except the hot melt) of polyethylene pipe on the market, though kind is more, but it is very inconvenient in the use, its threeway, elbow, directly, very stiff, this brings a lot of inconvenience to circuit design, for the shunting that makes water rationally should be selected rational caliber for use, also need carry out the otherwise combined of reducing.When if the great disparity of the caliber before and after the reducing is big, then will count step conversion combination just can finish, this has increased the use amount of pipe connector undoubtedly, also increased simultaneously the installation work-hour expense, this is unfavorable for reducing engineering cost, because the link of combination increases, the possibility of percolating water has also just increased thereupon in addition.Also there are some problems in the connectivity robustness aspect of pipe joint and pipe, especially comparatively outstanding aspect big caliber, when laying non-pipe laying road in the bigger rolling country of the gradient, reasons such as deadweight owing to hydraulic pressure and pipeline itself, take off the pipe phenomenon and produce, the normal operation that this not only influences engineering causes the damage of some pipe fittings, also causes unnecessary doing over again simultaneously.

The model utility content:

The purpose of this utility model is in order to overcome above deficiency, and a kind of installation that various plastic pipes connect, easy to use that is applicable to is provided, and installs fast, saves mounting cost, reduces engineering cost, the combined type rapid pipe joint that sealing effect is good.

The purpose of this utility model is achieved like this:

The rapid pipe joint of the utility model combined type comprises the fittings body 1 that contains pipeline attachment hole 2 and seal groove 3, be contained in the seal ring 5 in the seal groove, one end stretches into the locking card 6 that at least two claws are arranged respectively on its front inner wall in the seal groove, is sleeved on that the fittings body periphery is attached thereto and front inner wall is close to adjusting fixed block 8 on the anterior periphery of locking card.

Above-mentioned locking card front portion is a cone, and the fixed block front inner wall is the conical surface that cooperates with locking card front end cone.

Claw on the above-mentioned locking card is three, is evenly distributed on the locking card front inner wall.

Claw on the above-mentioned locking card is four, is evenly distributed on locking card front inner wall card.

Claw on the above-mentioned locking card is six, is evenly distributed on the locking card front inner wall.

Claw on the above-mentioned locking card is eight, is evenly distributed on the locking card front inner wall.

Above-mentioned adjusting fixed block 8 is a nut.

On the above-mentioned fittings body afterbody external pipe thread or Internal Pipe Thread are arranged, can be connected smoothly with the metal pipe element or the nonmetal pipe fitting of corresponding specification.

There are two ends to wait reducer union 10 with fittings body is connected with pipe joint respectively in the above-mentioned rapid pipe joint.

Above-mentioned waiting on reducer union one end has Internal Pipe Thread, can be connected smoothly with the metal pipe element or the nonmetal pipe fitting of corresponding specification.

When using the utility model, wait reducer union to be connected by of the present utility model with pipe joint, then plastic pipe one end to be connected is stretched into fittings body pipeline attachment hole, tighten when regulating the fixed block nut, under the effect of its conical surface, the locking card is pressed towards pipeline, the crown of claw punctures pipe surface, catch pipeline to produce axial motion with the locking card, the lower end surface of locking card compresses seal ring simultaneously, reaches the purpose of water shutoff.As long as will regulate the fixed block nut is screwed to suitable tightness and just can reaches the pipe purpose that neither the DecryptDecryption seal again can water shutoff.

The utility model is made the joint of various models, only need choose corresponding joint and required all the other links (as threeway, elbow, direct etc.) during use on demand just can make up, especially in the reducing combined aspects,, can both accomplish to settle at one go no matter it is much to need the great disparity of reducing size to have.Make the plug design that cooperates with the utility model joint for plastic tube have more its uniqueness, no matter caliber size, only with one 1/2 " stopper get final product (existing pipe connector, its plug be by the diameter making of pipe as if caliber from 20-90 then plug just have 8 kinds more than).

The utility model is applicable to the connection of various plastic pipes, and installation, easy to use is installed fast, saves mounting cost, reduces engineering cost, good sealing effect.

Embodiment:

Embodiment 1:

Fig. 1 has provided present embodiment 1 figure.Referring to Fig. 1, pipeline attachment hole 2 and seal groove 3 are arranged in the fittings body 1, external pipe thread 4 is arranged on its afterbody, O RunddichtringO 5 is contained on the interior seal groove of connecting body.Locking card 6 one ends stretch in the seal groove and contact with the O RunddichtringO.Locking card 6 is evenly distributed with six claws 7 as Fig. 2, its anterior cone 14 inwalls shown in Figure 3.Regulate fixed block---nut 8 is threaded on the connecting body and its front end conical surface 15 is close on the anterior cone of locking card.

As shown in Figure 1, plastic pipe is stretched in the pipeline attachment hole on the connecting body, fastening nut, under the effect of its conical surface, the locking card is pressed towards pipeline, crown on the claw on it punctures pipeline 9 surfaces and produces axial motion with the locking card, and meanwhile the lower end surface of locking card compresses the O RunddichtringO, reaches the water shutoff purpose.
