Abstract
The invention discloses a simple and easy hot melting technology for connection of a PVC pipe, in the method, the PVC pipe is connected through hot melting socket, and the method has the following brief process flows: heating up a pipe end to expand, cooling and shaping the pipe end, connecting the pipe line, heating up the pipe end for the second time, and cooling and shaping the pipe end. Gum water is unnecessary for the technology, so that water pollution caused by the gum water is avoided, and the technology is simple, convenient in operation, firm and reliable in connection, low in installation cost, and particularly suitable for home installation of pipes.
Description
Technical field
The present invention relates to the water supply and sewerage pipeline field, relate in particular to a kind of simple and easy technology of hot melt that the pvc pipe road connects that is used for.
Technical background
Traditional pvc pipe road Placement has two kinds: a kind of is that glue connects, and a kind of is that flexible seal ring connects.Though it is efficient and convenient that glue connects, but the hypotoxicity of glue itself still has certain application risk, practitioner's quality of particularly present domestic PVC house ornamentation pipeline industry is lower, when using, glue tends to leave over part glue at inner-walls of duct, cause water pollution, use this pipeline can the health of human body be worked the mischief for a long time; And another kind is the flexible seal ring connection, though certain flexible buffer function is arranged, can solve the influence of certain geology lifting, but setting tool complexity, and installation personnel and mounting process are had relatively high expectations, and the installation cost height often is applicable to large-scale engineering.The installation of house ornamentation pipeline require water quality not contaminated, and technology is simple, and is easy to operate.
Summary of the invention
The present invention has overcome deficiency of the prior art, and a kind of simple and easy technology of hot melt that the pvc pipe road connects that is used for is provided.
In order to realize above-mentioned purpose, adopt following technological scheme:
A kind of simple and easy technology of hot melt that is used for the connection of pvc pipe road may further comprise the steps:
(1) end to first pipeline heats enlarging, makes it can allow an end of second pipeline insert smoothly, the diameter of enlarging and depth visual situation and decide;
(2) flared end of first pipeline is cooled off, cooling timely can make enlarging temporarily finalize the design, and convenient second pipeline inserts;
(3) carry out pre-connection, second pipeline, one end is inserted one section degree of depth of the first pipeline flared end;
(4) the first pipeline flared tube ends is carried out double heating, make the pipe end deliquescing;
(5) first pipeline flared tube ends retract to second pipeline and closely contact, and carry out cooling and shaping, finish connection.
In the such scheme, further comprising the steps of:
(6) the circularity correction is carried out in the joint behind the cooling and shaping, make connection more attractive in appearance firmly.
In the such scheme, it is 32mm that step (1) adopts diameter, and length is that the heating head of 22mm heats.
Compared with prior art, the invention has the beneficial effects as follows: need not to use glue, avoided glue that water quality is polluted, technology is simple, and is easy to operate, firm and reliable connection, and installation cost is low, is specially adapted to the house ornamentation pipeline.
Description of drawings
Fig. 1 is a process flow diagram of the present invention.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
Technological process of the present invention may further comprise the steps (the DN32 supply pipe with the PVC material is an example) as shown in Figure 1:
(1) adopting diameter is 32mm, and length is the heating head of 22mm, and an end of first pipeline is heated enlarging, makes it can allow an end of second pipeline insert smoothly;
(2) flared end of first pipeline is cooled off, cooling timely can make enlarging temporarily finalize the design, and convenient second pipeline inserts;
(3) carry out pre-connection, second pipeline, one end is inserted one section degree of depth of the first pipeline flared end, depth visual situation and deciding;
(4) the first pipeline flared tube ends is carried out double heating, make the pipe end deliquescing, will avoid having influence on second pipeline during heating as far as possible;
(5) first pipeline flared tube ends retract to second pipeline and closely contact, and carry out cooling and shaping;
(6) the circularity correction is carried out in the joint behind the cooling and shaping, make connection more attractive in appearance firmly.
Be noted that in the whole connection procedure, two the pipeline pipe end outer surfaces and the internal surface of connection must clean free from admixture, otherwise can influence the connection effect.
Claims (3)
1. one kind is used for the simple and easy technology of hot melt that the pvc pipe road connects, and it is characterized in that may further comprise the steps:
(1) end to first pipeline heats enlarging, makes it can allow an end of second pipeline insert smoothly;
(2) flared end of first pipeline is cooled off;
(3) carry out pre-connection, second pipeline, one end is inserted one section degree of depth of the first pipeline flared end;
(4) the first pipeline flared tube ends is carried out double heating;
(5) first pipeline flared tube ends retract to second pipeline and closely contact, and carry out cooling and shaping.
2. simple and easy technology according to claim 1 is characterized in that further comprising the steps of:
(6) the circularity correction is carried out in the joint behind the cooling and shaping.
3. simple and easy technology according to claim 1 is characterized in that it is 32mm that described step (1) adopts diameter, and length is that the heating head of 22mm heats.
