Abstract
The valve core for ball valve disease one hollow sphere with identical upper and lower truncated plates and inner tube penetrating the sphere. The sphere has slot for controlling the rotation of the valve core and its end edge connected tightly with the inner tube. The manufacture process of the valve core includes the following steps: selecting hollow sphere in certain size, punching slot, turning the upper and the lower ports and boring the inner hole to required size; selecting inner tube in corresponding size and turning the lower end to eliminate outer ring; assembling the inner tube inside the sphere to hermetical connection; pressing the inner tube and the upper end of sphere inside mold to form a blank; and turning, polishing and cleaning. The present invention has high product quality, high use reliability and other advantages.
Description
(1) technical field
The present invention relates to a kind of ball valve core and manufacture method thereof.
(2) background technique
The ball valve core of prior art adopts casting mostly or is shaped and is processed into base, is shaped through processing again.Owing to exist such as defectives such as pore, burning into sand, impurity in the casting, leak in producing or leak outside, thereby make yield rate very low, this is to the cost of producing ball valve core is increased.Even qualified in addition casting ball valve core because casting technique makes the spool face became uneven even, influences the sealing and the reliability of valve.Compare the ball valve core that most advanced and sophisticated employing upsetting pressure method is produced at present, organizing of material is close, and quality is better relatively, but equipment is required height, and the ball valve wall unevenness is even, and is big to the consumption of copper material, the cost height.
(3) summary of the invention
The objective of the invention is to overcome above-mentioned ball valve core adopt cast form and upsetting pressure method produce in the low shortcoming of yield rate, provide that a kind of quality is good, yield rate is high, ball valve core of low cost of manufacture and good reliability and preparation method thereof.
For this reason, the present invention takes following technological scheme:
A kind of ball valve core comprises and cuts the interior pipe that upper and lower parallel mutually prismatic hollow ball is arranged and run through described spheroid, has the groove of the described valve core rotation of control on the described spheroid, and the end periphery of described spheroid directly closely is connected with the outer surface of described interior pipe.
The end periphery of described spheroid with described in the outer surface of pipe directly closely be connected to refer in particular to and be tightly connected.
Described groove is recommended as the back cover groove of indent, because not disconnection of bottom land, but the intensity of strengthening groove makes the trough rim of valve switch control be difficult for strain cracking in the using process repeatedly.
Described trough rim also can be the punching press trough rim, after the trough rim of opening is stamped, can strengthen the intensity of trough rim equally.
Concrete, also an end periphery of described spheroid and the outer surface of described interior pipe directly can be tightly connected, the other end is by managing the flanging sealing and fixing in described on described spheroid.
The preparation method of the spool of the said ball valve in front, comprise the steps: a, adopt the bulging process preparation to have the hollow ball of groove copper pipe, usually use bulging process, the workpiece that bulging is qualified on lathe, cut upper and lower straight mouthful also the boring endoporus to required size; The interior pipe of b, selection corresponding size; C, certain thickness outer shroud is removed in the lower end turning of interior pipe, make outside the underpart ring size corresponding with straight mouthful of size of hollow ball, then with interior pipe and spheroid assembling, pipe is tightly connected with the fixing of spheroid underpart in making; D, above-mentioned assembly is put into mould, interior pipe and spheroid upper end portion are pressed into close-connected blank; E, unnecessary material is removed in the upper and lower end turning of above-mentioned blank, polishing, clean.
For working life and the precision that makes valve further improves,, between step c and steps d, increase by an operating procedure e: add scolder at interior pipe and joint, spheroid end, add heat-sealable except that by the above-mentioned steps preparation.
Spheroid described in the preparation method is the spheroid that copper pipe adopts the bulging process preparation.
Described bulging process is the polyurethane bulging process.
Or described bulging process is a hydraulic bulging process.
Employing the present invention have the following advantages: 1, adopt bulging process to prepare spheroid, then interior pipe and ball seal are fixed, avoided the problem of pore, burning into sand and impurity in the casting, improved the yield rate of product; 2, improved operational safety; 3, reduced cost of production; 4, simple, convenient.
