Abstract
The utility model relates to a plastic ball valve having a metallic loose joint. The ball valve is characterized in that in the injection molding process of a plastic valve body, a ball shaft and a sealing ring are enclosed into the cavity of the valve body and a loose joint inner pipe and a sleeve pipe are integrated in an injection moulding way. The injection molding process realizes the seal and the assembly of the plastic ball valve. The plastic ball valve having a metallic loose joint has a simple structure, enables the plastic ball valve to be quickly and flexibly installed on a pipe fitting, solves the connection problem of plastic ball valves and metallic pipe fittings, and enlarges the range of application.
Description
The utility model relates to a kind of ball valve made of plastic, particularly with the ball valve made of plastic of metal union.
Before the utility model, ball valve made of plastic is made up of parts such as valve body, ball journal, seal ring, handles.Connecting end directly matches with the pipe fitting of liquid device system, installs inconvenient.Particularly when cooperating, difficulty more is installed with metal pipe element.And this mounting type can not guarantee that handle is in desirable position.Simultaneously, little because of the valve body connecting end intensity of plastics, when installing and use, cracked problem appears easily.
For addressing the above problem, common way is to increase flanged (FLGD) loose joint device at the ball valve connecting end.But this device, not only complex structure, part is many, sealing part is many, and installs easy inadequately.
The purpose of this utility model be to provide a kind of can eliminate above-mentioned defective, simple in structure, make ball valve made of plastic quick, the union of easy-to-install band metal.
For achieving the above object, the utility model is made up of the part of valve body, ball journal, seal ring, handle, sleeve pipe and the union of band metal.It is characterized in that valve body is in injection molding process, ball journal, seal ring are included in the valve body die cavity, also pipe and sleeve pipe in the loose joint are injection-moulded in simultaneously two connecting ends of valve body respectively, this injection molding process, and finished the sealing and the assembling work of ball valve made of plastic.
The employing of this structure and extraordinary Shooting Technique is compared with existing ball valve made of plastic; A kind of loose joint connecting end simple in structure, with low cost is provided.Because the valve body connecting end has been inlayed pipe and sleeve pipe in the loose joint when injection moulding, making it intensity increases.This kind ball valve made of plastic when mounted, handle is in desirable position easily.And, can make to install and more change jobs to become flexibly quick.Simultaneously, solve the problem that ball valve made of plastic is connected with metal pipe element, enlarged the application area of ball valve made of plastic.
Concrete structure of the present utility model is provided by following examples and accompanying drawing.
The ball valve made of plastic of band metal shown in the drawings union, by manage 4 in valve body 1, ball journal 2, seal ring 3, the loose joint, loose joint outer tube 5, attaching nut 6, sealing gasket 7, handle 8 and sleeve pipe 9 form.In the injection molding process of valve body 1, ball journal 2 and seal ring 3 are included in the valve body die cavity; And pipe 4 and sleeve pipe 9 in the loose joint be injection-moulded in two connecting ends of valve body 1 respectively, make it to be fixed into one.Injection moulding process has been finished the sealing and the assembling work of ball valve made of plastic simultaneously.Attaching nut 6 is enclosed within on the loose joint outer tube 5, with after being threaded, adds sealing gasket 7, carry out docking of pipe 4 in loose joint outer tube 5 and the loose joint again, tighten attaching nut 6, just finished the installation of ball valve made of plastic at loose joint outer tube 5 and the pipe fitting that will install.This kind installation, the handle 8 of ball valve made of plastic can be in 360 ° arbitrary position so that operating grip 8 reverses ball journal 2, adjust ball valve made of plastic breakdown and close.
