Description

PPR pipe

The technical field is as follows:

the utility model relates to a PPR pipe.

Background art:

PPR is a short name of tripropylene polyethylene, also called as a random copolymerization polypropylene pipe, has special welding and cutting tools, higher plasticity and economic price, is added with a heat insulation layer, has better heat insulation performance and smooth pipe wall, and is widely applied to the building industry, municipal administration, industry and agricultural field, such as building water supply and drainage, urban and rural water supply and drainage, urban gas, electric power and optical cable sheaths, industrial fluid delivery, agricultural irrigation and the like. However, the PPR pipe is thermally welded, and therefore, a welded joint is required to be connected, which causes a risk of leakage, and a raw material must be used to ensure sealability when connecting pipes for a threaded joint, which is troublesome and affects work efficiency.

The invention content is as follows:

the utility model aims at solving the problem among the prior art, provide a both ends and be provided with rubber seal, rubber seal non-deformable, drop moreover, the good PPR pipe of leakproofness when the pipe fitting docks.

In order to achieve the above purpose, the technical scheme of the utility model is that:

a PPR pipe comprises a PPR pipe body, wherein rubber sealing rings are mounted at two ends of the PPR pipe body, fixing grooves are formed in the side faces of the two ends of the PPR pipe body, an insertion hole communicated with the fixing grooves is formed in the side face of the PPR pipe body, and hook grooves are formed in the inner walls of the fixing grooves at two sides of the insertion hole; the inside of rubber seal's inside is provided with the ferrule, install the connecting strip with the inserted hole one-to-one on the side of ferrule, 2 blocks of elasticity cardboard that stretch into in the fixed slot from the inserted hole are installed to the symmetry on the connecting strip, install the pothook on the elasticity cardboard, the pothook links to each other with the groove activity joint that colludes that corresponds.

And a polyvinylidene fluoride layer is arranged on the outer side of the PPR pipe body.

The inner side of the PPR pipe body is provided with a nano silver antibacterial layer.

And an elastic supporting sheet is arranged between the 2 elastic clamping plates.

The utility model has the advantages that: the utility model discloses a PPR pipe, including the PPR pipe body that both ends all installed rubber seal, the inside of rubber seal is provided with the metal ring, makes rubber seal be difficult to deform when the pipe fitting is connected and is extruded, no matter adopt the butt fusion joint to connect the pipe fitting directly or adopt the screwed joint to carry out the pipe fitting to connect, can both improve the leakproofness of pipe fitting connection; install the connecting strip with the inserted hole one-to-one on the side of ferrule, the symmetry is installed 2 elastic clamping plates that stretch into the fixed slot from the inserted hole on the connecting strip, installs the pothook on the elastic clamping plate, and the pothook links to each other with the groove activity joint that corresponds, and the design of elastic clamping plate and pothook makes rubber seal fix at PPR pipe body both ends, can dismantle convenient operation by manual extrusion elastic clamping plate moreover.

Description of the drawings:

fig. 1 is a schematic structural view of the present invention;

fig. 2 is an enlarged view of a point a in fig. 1.

The specific implementation mode is as follows:

in order that those skilled in the art will better understand the inventive arrangements, further details of the invention are provided below with reference to the accompanying drawings and embodiments.

As shown in fig. 1-2, a PPR pipe includes a PPR pipe body 2 having rubber seal rings 1 mounted at both ends thereof, and as a preferred scheme, a polyvinylidene fluoride layer 7 is disposed on the outer side of the PPR pipe body 2 to improve the wear resistance of the PPR pipe body 2, a nano silver antibacterial layer 8 is disposed on the inner side of the PPR pipe body 2, and the nano silver antibacterial layer 8 is formed by spraying a nano silver antibacterial agent into the PPR pipe body 2, and has the characteristics of strong sterilization, good durability and no drug resistance. Fixed slot 3 has all been seted up in the side at 2 both ends of PPR pipe body, and fixed slot 3 is located the inside at 2 both ends of PPR pipe body, and preferred longitudinal symmetry sets up 2. The PPR pipe is characterized in that the side surface of the PPR pipe body 2 is also provided with an insertion hole 31 communicated with the fixing groove 3, and the inner walls of the fixing grooves 3 on the two sides of the insertion hole 31 are provided with hook grooves 4. Rubber seal 1's inside is provided with metal ring 33, and metal ring 33 makes rubber seal 1 receive extrusion back non-deformable, avoids rubber seal 1 to appear the gap after warping and leads to sealed effect not good.

Install on the side of ferrule 33 and insert the connecting strip 5 of 31 one-to-one, 2 blocks of elastic clamping boards 6 that stretch into in the fixed slot 3 from the insert hole 31 are installed to the symmetry on connecting strip 5, install pothook 61 on the elastic clamping board 6, pothook 61 links to each other with the 4 activity joint of colluding groove that correspond. 2 elastic clamping plate 6 need the operator to be close to 2 elastic clamping plate 6 each other with the hand extrusion when inserting in

fixed slot

3, 2 mutual principle behind elastic clamping plate 6 entering fixed slot 3,

pothook

61 and 4 activity joint in colluding groove can prevent that rubber seal 1 from following the 2 both ends of PPR pipe body and dropping simultaneously. As an optimal scheme, an elastic support sheet 9 is installed between 2 elastic clamping plates 6, so that an elastic fixing structure formed by the 2 elastic clamping plates 6 is more stable.

The PPR pipe comprises a PPR pipe body, rubber sealing rings are mounted at two ends of the PPR pipe body, metal rings are arranged inside the rubber sealing rings, so that the rubber sealing rings are not easy to deform when pipe fittings are connected and extruded, and the sealing performance of pipe fitting connection can be improved no matter whether the pipe fittings are directly connected by adopting a welding joint or connected by adopting a threaded joint; install the connecting strip with the inserted hole one-to-one on the side of ferrule, the symmetry is installed 2 elastic clamping plates that stretch into the fixed slot from the inserted hole on the connecting strip, installs the pothook on the elastic clamping plate, and the pothook links to each other with the groove activity joint that corresponds, and the design of elastic clamping plate and pothook makes rubber seal fix at PPR pipe body both ends, can dismantle convenient operation by manual extrusion elastic clamping plate moreover.
