Description
Technical field
The present invention relates to a kind of methods that PPR pipe road replaces the die head of internal thread and replaces internal thread using this die head.
Background technology
PPR water pipe is widely used in industry and average family.Water pipe is all embedded in wall by the decoration of modernization, is being discharged
The internal thread tube head of water pipe is exposed in metope or ceramic tile trepanning mode in position, then connects the connections such as tap or triangle vavle
Attachment.
Since market PPR internal thread tube head quality is irregular, and many businessmans are used copper internal thread non-to pursue high profit
It is often thin, to reduce cost.After using more than certain time limit, the internal thread in tube head will appear cracking, loosen, damaged chip off-falling etc.
Phenomenon causes leak can not normal use.
Conventionally, it is necessary to ceramic tile metope be broken, the internal thread tube head of damage is cut, weld interior fiber tube again
Head.Operation is extremely difficult for ordinarily resident user in this way, they can only seek help from decoration company or hydropower installation repair people
Member just replaces.It replaces and after completing also needs to that mason is asked to repair metope again.This scheme operating process destroys greatly metope,
And it takes considerable time and manpower and materials.Such case is very common, therefore brings great inconvenience to repair.
Invention content
In order to solve the above technical problems, the present invention provides a kind of die head that can be convenient for changing internal thread and using this die head
The method for replacing internal thread.
Replace internal thread die head take a die head and silk pressing mould first two, it is described to take a die head as described below.
Described to take one end of a die head for external screw thread, the external screw thread can be matched with the internal thread of PPR pipe, described to take silk
The other end of die head is a cylinder, has a connection internal thread at the center of the cylinder, the connection internal thread can be with heat melting device
Heating board be connected by screw.It is described to take the material of a die head for aluminium.
The structure of the silk pressing die head is as described below.
One end of the silk pressing die head is bar, and the diameter of the bar is less than the minor diameter of internal thread of PPR pipe and more than PPR pipe
Female end face diameter, the length of the bar are more than the length of the female thread portion of PPR pipe, i.e.,：The bar can support PPR pipe
End-face hole inner face.The bar can be cylinder, pipe, square column, square tube or threaded rod.The other end of the silk pressing die head is
One cylinder has a connection internal thread, the connection internal thread that can pass through spiral shell with the heating board of heat melting device at the center of the cylinder
It tethers and connects.The material of the silk pressing die head is aluminium.
It is using the method for taking a die head and the silk pressing die head to replace PPR pipe internal thread：
A. by the internal thread for taking a die head to be screwed into PPR pipe, make described a die head to be taken with internal thread to coordinate；
B., the silk pressing die head is fixed on to the side of the heating board of heat melting device；
C. by the other side of the heating board for taking a die head to be fixed on heat melting device；
D. new internal thread to be replaced is installed on the silk pressing die head；
E. by heat melting device energization 4-5 minutes；
F. heat melting device is slowly pulled out, the old internal thread heated can also remove therewith；
G. the heating board of heat melting device is overturn into 180 degree, makes silk pressing die end towards PPR pipe；
H. the new internal thread heated on silk pressing die head is directed at PPR pipe, exerts oneself in fever back, internal thread is made to enter PPR pipe,
And ensure that the end face of new internal thread is concordant with the end face of PPR pipe；
I. heating board and silk pressing die head are taken out；
J. colloid extra in pipeline is removed with hole making drill.
In above-mentioned steps, the sequence of a, b, c, d can be abcd or bacd or abdc or bdac.
Above-mentioned technical proposal has the beneficial effect that：It is easy to operate, appearance is beautiful, avoid extensive damage wall, improve
Working efficiency, saves resources costs.But there is also certain deficiencies, since the outer surface of internal thread is rough outer circle
Cylinder so that internal thread and PPR pipe contact area are smaller, when using new internal thread thicker, may melt the inner wall of former PPR pipe
It is thin to coordinate, it will cause to seep water after replacing in this way, so that this programme is less reliable in any case.
In order to solve the above technical problems, the present invention also provides another solution, it is specific as follows：
A. by the internal thread for taking a die head to be screwed into PPR pipe, make described a die head to be taken with internal thread to coordinate；
B., lengthening punch-pin and cavity plate are fixed on to the side of the heating board of heat melting device；
C. by the other side of the heating board for taking a die head to be fixed on heat melting device；
D. by heat melting device energization 4-5 minutes；
E. heat melting device is slowly pulled out, the old internal thread heated can also remove therewith；
F. the heating board of heat melting device is overturn into 180 degree, makes lengthening punch-pin side towards PPR pipe；
G. punch-pin will be lengthened to extend into PPR pipe, PPR pipe heating is allowed to melt；Short internal thread component is placed in cavity plate simultaneously,
The excircle part of short internal thread component is set to melt；
H. extension die and cavity plate are removed, short internal thread component is rapidly inserted into PPR pipe；
I. after cooling, colloid extra in pipeline is removed using hole making drill.
The advantageous effect of this scheme is that welding is reliable, can bear the pressure of 2.5MPa, will not seep water, and can be in PPR
It is used when managing relatively thin.Certainly, there is also certain deficiencies for this scheme, i.e., not beautiful enough.
Description of the drawings
