Abstract
The utility model relates to a pipeline connecting piece, aims to overcome the defects in the prior art, and provides a bypass pipe fitting compatible with the connection between PVC pipes and PE pipes. The structure includes a first end and a second end for connecting pipes made of different materials, and is characterized in that the first end is sleeved and connected with a rubber sealing ring, and an annular reverse buckle is arranged at the second end. The first end of the bypass pipe fitting is connected with a hard PVC pipe through adopting the rubber sealing ring for sealing, and the interference fit is adopted between the rubber sealing ring and the hard PVC pipe, therefore, the connection manner can effectively prevent the generation of problems such as leakage, separation and the like. The bypass pipe fitting can be used for producing products of Phi 12, Phi 16 and Phi 20 specifications, and can be used for connecting PE pipes of corresponding specifications. The connection of the second end of the bypass pipe fitting and the PE pipe adopt the reverse buckle manner, the connection of the annular reverse buckle and the PE pipe can effectively prevent the PE pipe from being separated during the use, and the operation is simple and convenient.
Description
Technical field
The utility model relates to a kind of pipe joint, say so more specifically connect hard PVC pipe and PE pipe effective bypass pipe fitting.
Background technique
What be used for doing main pipe and arm in the present domestic water-saving irrigation industry mostly is PE thin walled hose and hard PVC pipe, and the bypass pipe fitting commonly used between two kinds of pipes is communicated with.But because of hard PVC pipe and phenomenons such as easily coming off often appears leaking, in being connected of bypass pipe fitting, so the PE thin walled hose that adopts is used as main pipe and arm more.Owing to reasons such as properties of materials, PE thin walled hose ageing resistance can not show a candle to the hard PVC pipe.Therefore the hard PVC pipe is used for water-saving irrigation its special advantages, is embodied in aspects such as recycling, anti-aging especially.But owing at present domesticly also do not have the link that is used to connect the hard PVC pipe preferably, thereby solve this type of problem and seem particularly important.Leakage proof, Drop-proof etc. also become the problem that must solve when being connected with the hard PVC pipe simultaneously.
Summary of the invention
Technical problem to be solved in the utility model is the defective that overcomes prior art, provides a kind of and can be compatible with the bypass pipe fitting that connects between pvc pipe and the PE pipe.
This patent is achieved through the following technical solutions above-mentioned purpose.
The bypass pipe fitting of the utility model design comprises first end and second end that connect the different tubing of two kinds of materials, it is characterized in that described first end is socketed with rubber seal, and described second end is provided with annular back-off.First end of bypass pipe fitting is connected with the hard PVC pipe and adopts the rubber seal sealing, and adopts interference fit between rubber seal and hard PVC pipe, and this Placement can prevent seepage and the generation of problem such as come off effectively.This bypass pipe fitting can be produced ￠ 12, and ￠ 16, and the product of ￠ 20 specifications can be used for connecting the PE pipe of corresponding specification.Second end of bypass pipe fitting and PE pipe is connected the back-off mode that adopts, and annular back-off and PE manage and be connected that the PE pipe comes off in the time of can effectively preventing to use, and easy and simple to handle.
In order further to improve the seal degree between the pipe fitting, this patent can also adopt following corrective measure.
Described first end is provided with the groove that is used for the socket rubber seal, and the width of groove is greater than the width of rubber seal.
Described rubber seal has the upper limb of a protrusion and the lower edge of a protrusion, and the distance that described lower edge protrudes is greater than upper limb.
Described second end is provided with 2 ~ 5 layers of annular back-off, and optimum structure is for being provided with the annular back-off that haves three layers.
This patent has solved being connected and problem that connection comes off, leaks between hard PVC pipe and PE pipe, be widely used in agricultural irrigation, the generation of problem such as can prevent seepage effectively and come off, easy and simple to handle, and can reasonable use hard PVC pipe and the PE pipe, make the structural design of pipeline more reasonable, meet the character characteristics of self, have longer working life.
Description of drawings
Fig. 1 is this patent embodiment's a structural representation;
Fig. 2 is the sectional view of Fig. 1;
Fig. 3 is a rubber seal structural representation among Fig. 1;
Fig. 4 is a bypass agent structure schematic representation among Fig. 1.
Embodiment
The utility model is described further by embodiment below in conjunction with accompanying drawing.
A kind of bypass pipe fitting as shown in Figure 1 comprises first end 1 and second end 4 that connect the different tubing of two kinds of materials, and described first end 1 is socketed with rubber seal 2, and described second end 4 is provided with shellring shape back-off 3.In conjunction with Fig. 2 and shown in Figure 4, can find out cooperating between first end 1 and the rubber seal 2 in detail, described first end 1 is provided with the groove 5 that is used for socket rubber seal 2, the width of groove 5 is greater than the width 2 of rubber seal, make rubber seal 2 have up and down space, convenient and pvc pipe is pegged graft.As shown in Figure 3 for the described rubber seal 2 of the tightness that improves sealing has the upper limb 21 of a protrusion and the lower edge 22 of a protrusion, because the pvc pipe internal pressure is greater than the pipe pressure outside, the distance that described lower edge 22 protrudes is greater than upper limb 21.
During use, first end 1 of bypass pipe fitting is connected with the hard PVC pipe and adopts rubber seal 2 sealings, and adopts interference fit between rubber seal 2 and hard PVC pipe, and this Placement can prevent seepage and the generation of problem such as come off effectively.This bypass pipe fitting can be produced ￠ 12, and ￠ 16, and the product of ￠ 20 specifications can be used for connecting the PE pipe of corresponding specification.Second end 4 of bypass pipe fitting and PE pipe is connected three layers of back-off 3 mode that adopt, and annular back-off 3 and PE manage and be connected that the PE pipe comes off in the time of can effectively preventing to use, and easy and simple to handle.
