Abstract
The utility model relates to a pipe joint unit, particularly a pipe joint unit which is used in pipelines for conveying fluids. Because the joint position of the pipe joint is provided with a circular protuberant ridge which is higher inside, lower outside, and is aslope, as long as the pipe joint is used by matching with an annular fixing and sealing device whose internal diameter is slightly bigger than the external diameter of a pipe, fluids can be prevented from leaking well and the pipe joint can be easily installed and used.
Description
The utility model relates to a kind of pipe joint unit, a kind of specifically pipe joint unit that is used for mobile delivering pipe.
Pipe coupling is a kind of accessory commonly used in a kind of people's daily life work, as water pipe, oil pipe etc., pipe coupling must have good seal, pipe coupling commonly used at present, generally all be that curl is done in its joint, as application number is 94227388, and denomination of invention is a kind of model utility of low-pressure water, the floating type union of tracheae net, and it is to be made of with the locking nut 3 of locking coupling head female unsteady coupling head 4.This screw nut structure is often used and can be produced the gap, and because itself structure always is difficult to accomplish the seepage that prevents fluid fully.
The purpose of this utility model is that invention a kind ofly can really prevent seepage and pipe joint unit easy to install fully.
The utility model can be achieved through the following technical solutions:
A kind of liquid conveying pipe device, by pipe coupling (1) be used for liquid conveying pipe being fixed and being formed with the fixed seal ring (2) of joint sealing, fixed seal ring (2) is circular, its internal diameter is slightly larger than outer diameter tube, and there is the rib (3) of the projection that is circular described pipe coupling (1) joint.
In above-mentioned technological right requires, described a kind of liquid conveying pipe piecing devices, there is the low inside and high outside slope shape that is of rib (3) of the projection that is circular described pipe coupling (1) joint.
Because the rib (3) of the projection that is circular is arranged in described pipe coupling place, and the low inside and high outside slope shape that is is used in combination with fixing seal device (2) that in the form of a ring its internal diameter is slightly larger than outer diameter tube and just can well prevents that fluid leaks and installation and use are all very convenient.
Below in conjunction with accompanying drawing the utility model being done further enforcement falls to illustrate:
Figure 1 shows that the utility model structural representation;
Figure 2 shows that the utility model structure user mode schematic representation;
As shown in Figure 1, on the contrary a kind of conduit pipeline piecing devices of this enforcement, it is by water pipe adapter 1 and be used for water pipe being fixed and being formed with the fixed seal ring 2 of joint sealing, fixed seal ring 2 is circular, its internal diameter is slightly larger than outer diameter tube, there is the rib 3 of the projection that is the figure ring-type water pipe adapter 1 joint, its low inside and high outside slope shape that is.In use, because the rib 3 low inside and high outside slope shape that are, so water pipe is easy to be inserted in water pipe adapter, at this moment with after seal ring 2 cover water inlet pipes and the water pipe adapter 1, only needs with instruments such as pliers its clamping is got final product, as shown in Figure 2.Because rib 3 is low inside and high outside, the water in the pipe is difficult to flow out, so it has good sealing.
Claims (2)
1. liquid conveying pipe piecing devices, by pipe coupling (1) be used for liquid conveying pipe being fixed and being formed with the fixed seal ring (2) of joint sealing, fixed seal ring (2) is circular, its internal diameter is slightly larger than outer diameter tube, it is characterized in that: there is the rib (3) of the projection that is circular described pipe coupling (1) joint.
2. a kind of liquid conveying pipe piecing devices according to claim 1 is characterized in that: there is the low inside and high outside slope shape that is of rib (3) of the projection that is circular described pipe coupling (1) joint.
