Background technique
PP-R (polypropylene random) pipe be also known as three type PA tubes and be called polypropylene random copolymer pipe or
PPR pipe has energy-saving material-saving, environmental protection, high-strength light, corrosion-resistant, inner wall smooth non-scaling, construction and maintenance simplicity, uses the longevity
The advantages that long is ordered, it is defeated to be widely used in building water supply and drainage, town and country plumbing, gas, electric power and cable jacket, industrial fluids
It send, construction industries, municipal administration, industry and the agriculture field such as agricultural irrigation.PP-R pipe is using atactic copolymerized polypropene through being extruded as pipe
Material, injection molding become pipe fitting.
With the popularization and application of plastic tube, the type of pipe fitting joint is also more and more, with the continuous liter of architecture storey
Height, it is incident be Running-water Company output hydraulic pressure it is also higher and higher, hydraulic pressure in plastic water pipe is high, this connects pipe fitting
The sealing performance of head is it is also proposed that higher requirement.Current water supply pipe fitting, be by silk mouth wind unsintered tape, by silk mouth with
It is sealed between unsintered tape.Such structure is first is that keep construction complicated, working efficiency is low, each connector requires to carry out
Raw material band winding；The aging of two raw material bands often results in connector and poorly sealed leak occurs.In addition, relatively high in existing pipe fitting joint
Shelves have a metal joint, and when installation is threadedly engaged by movable nut with plastic tube, and its structure is complicated, manufacturing cost is high, installation is numb
It is tired, and be easy to loosen using the threaded connection of movable nut and plastic tube for a long time, influence sealing effect.
Based on the above status, it is necessary to a kind of structure is simple, it is easy for installation, at low cost, be convenient for later maintenance and maintenance, no
Easily cause the novel PP-R water supply pipe fitting sealing locking structure of leakage accident.
Utility model content
In entire mechanical structure field, pipe fitting connection is a kind of common mechanical structure, when needing circulated gases in pipe fitting
Or it just needs to be sealed pipe fitting junction when liquid.Common pipe fitting connection type is to be connected through a screw thread and carry out close
Envelope, Normal practice is exactly to process O-ring slot, is sealed by O-ring, and O-ring is generally rubber and is made, and this structure is to one
As seal request be able to satisfy substantially, but more demanding to the processing quality of O-ring, slot, and when having inside sealing high pressure, sealing
Effect is poor, is easy failure.Simple being connected through a screw thread has been unable to meet with inner seal rings sealing to pipe fitting connection sealing
Requirement.In view of problem above, the utility model provide a kind of structure it is simple, it is easy for installation, at low cost, convenient for the later period
Care and maintenance does not easily cause the novel PP-R water supply pipe fitting sealing locking structure of leakage accident.
In order to realize above-mentioned purpose of utility model, the utility model the following technical schemes are provided:
A kind of PP-R water supply pipe fitting sealing locking structure in the utility model, including terminal pad and hasp, the terminal pad
It is directly connected through a screw thread with the PP-R water supply pipe fitting of locking to be sealed, middle position is equipped with and takes outside the side of the terminal pad
Fixed point is detained, middle position is equipped with hasp groove outside the other side of the terminal pad, connects hasp on the hasp fixed point
Fixing end, the free end of the hasp can freely swing within a certain angle, and it is recessed that the free end of the hasp can be inserted into hasp
In slot, the top of the terminal pad is equipped with o-ring groove, O-shaped elastic tape can be put into the o-ring groove, when two companies
When connecing disk and being attached, respective O-shaped elastic tape offsets elastic packing.
The inner wall of the terminal pad is provided with internal screw thread, the inner wall internal screw thread of the terminal pad and the PP-R of locking to be sealed
The external screw thread of the outer wall of water supply pipe fitting one end matches.The internal diameter of the terminal pad is equal to the PP-R water supply pipe fitting of locking to be sealed
Outer diameter.
The junction of the terminal pad and the PP-R water supply pipe fitting of locking to be sealed is provided with sealing rubber ring.
Stainless steel, aluminium alloy, plastics, PVC, any one of PPR or RFPP may be selected in the material of the terminal pad.
The material of the hasp should have certain toughness.It according to construction can need that suitable material is selected to make, it
It is contemplated that hasp itself may be made to generate certain deformation, to keep away when toughness is mainly in hasp insertion hasp groove
Exempt from hasp to fracture, so being contemplated that this point in selection.
Advantages and beneficial effects of the utility model lie in that provide a kind of structure it is simple, it is easy for installation, at low cost, be convenient for
Later maintenance and maintenance do not easily cause the novel PP-R water supply pipe fitting sealing locking structure of leakage accident.
