Problems solved by technology

At the corner of the pipeline, an angled connecting pipe is used to connect two straight PVC pipes. Generally, the connecting pipe is made of a 90-degree elbow pipe. In areas with complex terrain, such as when the turning angle is a non-standard angle, It is necessary to use multiple elbow pipes and multi-section straight pipes for connection, which affects the construction progress and frequent turns make the pipes prone to blockage and affect the drainage speed

Embodiment 1

[0073] according to Figure 1 to Figure 6 As shown, a PVC plastic pipe set described in this embodiment includes a straight pipe Q and a connecting pipe P. A socket is formed at one end of the straight pipe, and the inner diameter of the socket is equal to the outer diameter of the straight pipe.

[0074] The connecting pipe includes a socket end 1 , a bent portion 2 and a socket end 3 integrally connected in sequence; the outer diameter of the socket end and the inner diameter of the socket end are equal to the outer diameter of the straight pipe.

[0075] In the initial state of the connecting pipe, the angle between the axial direction of the socket end and the socket end is 160-175°;

[0076] The bending part includes an inner pipe part 201 and an outer pipe part 202 located outside the inner pipe part; the socket end, the inner pipe part and the socket end of the connecting pipe are integrally injection-molded by conventional PVC materials, and the inner pipe A helical s...

Embodiment 2

[0081] This embodiment makes further limitations and descriptions on the basis of embodiment 1, specifically:

[0082] The conductive PVC material comprises the following components by weight percentage:

[0083] PVC 60

[0084] Carbon Black 15

[0085] Conductive polyaniline 15

[0086] Polyethylene wax 2

[0087] Triphenyl phosphate 7

[0088] Magnesium Stearate 1

[0089] Among them, the particle size of carbon black is 0.2 μm

[0090] The preparation method of described conductive PVC material is:

[0091] 1) Put PVC and polyethylene wax into the mixing machine and knead, and when the PVC is in a viscous state, add other components to knead together;

[0092] 2) Send the material in the previous step into the extrusion granulator, and extrude to obtain PVC pellets;

[0093] Next, the PVC pellets are sent into the injection molding machine for injection molding to form the connecting pipe.

[0094] Between two adjacent straight pipes, and between the straight pipes...

Embodiment 3

[0104] combine Figure 7 , Figure 8 , as shown, this embodiment makes further limitations and descriptions on the basis of embodiment 1 or 2, specifically:

[0105] The straight pipe is formed by cutting a continuous pipe. When the pipe is extruded, a socket mouth is formed at a set distance, and the socket mouth is cut at the middle position by a cutting machine to form the described The socket, the pipe is cut at the part between two adjacent sockets to form two sections of the straight pipe.

[0106] The equipment for molding said pipes includes an extruder 61, a head die 62, a vertical forming device 63, a vacuum setting spray box 64, a tractor 65, a cutting machine 66 and a stacking pipe rack 67 arranged in sequence; The head and die are connected to the discharge end of the extruder.

[0107] The outer end of the mandrel of the nose die is connected with a connecting rod 621, and the other end of the connecting rod is connected with two stoppers 622, and the distance...

Abstract

The invention discloses a PVC (Polyvinyl Chloride) plastic tube suite. The PVC plastic tube suite comprises a straight tube and a connecting tube, wherein a faucet is molded at one end of the straighttube; the inside diameter of the faucet is equal to the outside diameter of the straight tube; the connecting tube comprises a spigot end, a bending part and a faucet end sequentially and integrallyconnected with one another; the outside diameter of the spigot end and the inside diameter of the faucet end are equal to the outside diameter of the straight tube; the bending part comprises an innertube part and an outer tube part which is positioned outside the inner tube pipe; the spigot end, the inner tube part and the faucet end of the connecting tube are subjected to integrated molding injection by adopting conventional PVC materials; a spiral spring is arranged in the inner tube part in an embedding manner; the outer tube part is subjected to integrated molding injection by adopting conductive PVC materials; and electrode rings are respectively arranged in the two ends of the outer tube part in an embedding manner, and the two electrode rings are connected with an electrode extending out of the outer tube part. According to the PVC plastic tube suite disclosed by the invention, an angle of the bending part can be flexibly adjusted, so that laying of pipelines in a variety of complex terrain areas can be adapted; and therefore, the construction flexibility is larger.

Description

technical field [0001] The invention belongs to the field of plastic pipes, in particular to a PVC plastic pipe set. Background technique [0002] Rigid PVC plastic pipes are often used for laying sewage pipes. Two adjacent PVC pipes are usually connected by sockets, that is, a socket with an inner diameter equivalent to the outer diameter of the PVC pipe is processed at one end of the PVC pipe, and the socket is connected to the adjacent PVC pipe. One end of the tube is connected by a sealing ring or bonded by an adhesive. At the corner of the pipeline, an angled connecting pipe is used to connect two straight PVC pipes. Generally, the connecting pipe is made of a 90-degree elbow pipe. In areas with complex terrain, such as when the turning angle is a non-standard angle, It is necessary to use multiple elbow pipes and multiple straight pipes for connection, which affects the construction progress and frequent turns make the pipes prone to blockage and affect the drainage s...
