Description
Technical field
The utility model relates to the improvement of a kind of PE ball valve and manufacture method thereof.
Background technique
Along with a large amount of uses of PE (polyethylene) pipeline in the gas supply pipe net, the demand of PE ball valve is also increasing.Yet the production technology of the PE ball valve of market sale at present mainly is the production technology with reference to metal ball-valve, causes existing P E ball valve to have the following disadvantages:
Because PE material itself, it is difficult to stably guarantee to be difficult to be guaranteed on the size, the particularly control to seal distance in machining process, causes in the process of producing product quality conformance poor, the difference in torque opposite sex greatly, problem such as the finished product rate is low.In addition, big model ball valve is that limit assembling side weld connects, and is difficult to check the correctness (sealing) of assembling in welding process, just can check after having only welding, has caused very big waste.
The model utility content
First technical problem that the utility model solves provides a kind of reasonable in design, makes things convenient for processing and assembling and detection, thereby improves the PE ball valve of product yield.
Second technical problem that the utility model solves provides a kind of PE ball valve manufacture method, makes this method can guarantee size and the convenient assembling correctness of checking than being easier in machining process, and the product yield is higher.
For solving first technical problem, the utility model adopts first technological scheme:
A kind of PE ball valve, comprise valve body and the end pipe that is connected with the valve port of valve body, this valve body comprises shell, is arranged on spool and spool driving mechanism in the shell, this valve port is arranged on the shell, wherein: be welded with electric melting pipe fittings in the described valve port, the end that this electric melting pipe fittings contacts with described spool is provided with seal ring and supporting sleeve.
As one of improving: be embedded with electric heating wire on the described electric melting pipe fittings.
As two of improvement: described spool driving mechanism comprises and is plugged in the described shell and the valve rod that cooperates with described spool, and is set in the bonnet on this valve rod.
As three of improvement: described valve body comprises two valve ports.
For solving second technical problem, the utility model adopts second technological scheme:
A kind of PE ball valve manufacture method may further comprise the steps:
S10: assemble valve body and electric melting pipe fittings respectively, wherein this valve body comprises shell, is arranged on spool and spool driving mechanism in the shell, and this electric melting pipe fittings one end is provided with seal ring and supporting sleeve;
S20: this electric melting pipe fittings is inserted in the valve port of valve body, make that being provided with an end of seal ring and supporting sleeve connects with spool in the valve body and cooperate;
S30: detect the sealing and the moment of torsion of electric melting pipe fittings and valve body, if qualified then carry out step S40; If defective then adjust the length that electric melting pipe fittings inserts valve body, and carry out this step again.
S40: electric melting pipe fittings and valve body are welded;
S50: will hold the pipe and the valve port of valve body to weld.
As one of improving: be embedded with electric heating wire on the described electric melting pipe fittings; Described valve body comprises two valve ports.
As two of improvement: in described step S30, the end face alignment of described electric melting pipe fittings and described valve port need be detected again.
Compared with prior art, the beneficial effect of the utility model first technological scheme is:
(1) simple in structure, convenient processing
Be placed with seal ring and supporting sleeve in the existing combustion gas PE ball valve end pipe, and the overall structure more complicated, make PE valve (especially big model) in course of working, cannot say for sure to demonstrate,prove the size of these structures.And the utility model is placed into structures such as seal ring, supporting sleeve in the electric melting pipe fittings, and overall structure is simplified, thus problem such as it is poor to have solved the quality conformance that PE ball valve processing dimension instability brings, and the difference in torque opposite sex is big, and the finished product rate is low.
(2) the convenient detection improved the product yield
The end pipe of existing P E ball valve is last welding, can only guarantee distance between seal ring by welding, and it is bigger so just to cause quality of product particularly to operate the moment of torsion difference, in case having welded quality problems appear and just can only be with product rejection.And the utility model is arranged on seal ring and supporting sleeve in the electric melting pipe fittings, therefore can carry out moment of torsion and sealing detection after in electric melting pipe fittings being inserted into the corresponding valve port of valve body, in time adjust both cooperation positions, just can carry out moment of torsion and the detection of rice envelope letter, therefore can greatly improve the product yield and need not to wait the product manufacturing to finish.
PE ball valve of the present utility model has in a word not only been simplified processing, has improved quality of processing, also for the follow-up inspection of hermetic seal that carries out before welding provides convenience, thereby has improved the acceptance rate of product.
Compared with prior art, the beneficial effect of the utility model second technological scheme is: conventional P E fuel gas ball valve is by guarantee the distance between seal ring in welding, in case welded, even if seal bad or the operation moment of torsion just can not repair again and can only scrap too greatly.And the change owing to part and manufacture method of this manufacture method, make and before welding valve body and electric melting pipe fittings, can seal and the moment of torsion inspection, avoided to detect after the welding of conventional P E fuel gas ball valve whether qualified defective, not only can improve welding quality, also greatly improve the product yield.
