Abstract
The utility model relates to a valve device, composed of a valve control body comprising a valve control part and a connecting part, a sleeve joint core, a nut, and a clamping ring. The connecting part is provided with screw thread, a cone slope tapered inward and a groove. The sleeve joint core is provided with a valve sleeve joint part engaged with the connecting part and a pipe sleeve joint part connected with pipes. The nut is connected with the connecting part through the screw thread. The clamping ring is positioned between the sleeve joint core and the nut. The utility model is especially suitable for connecting with aluminum plastic laminated pipes or plastic pipes. The utility model has the advantages of fine sealing performance, fine connection strength and convenient installation.
Description
The utility model relates to a kind of valving that is connected with pipeline.
Traditional valve is connected usually with being threaded or flange connection (as shown in Figure 1) with pipeline.This Placement is obviously having its narrow limitation with aluminium-plastic composite pipe or plastic tube (being called for short pipe down) when being connected, because pipe material softness, the anti-leak performance under pressurized state is very poor.
The purpose of this utility model is the defective at above-mentioned prior art, provides a kind of valving of being connected with aluminium-plastic composite pipe or plastic tube of being specially adapted to, to improve its sealability.
The utility model is realized in the following way: this valving is made up of the valve control body that comprises valve control portion and joint, socket core body, nut and hold-down ring.Joint is provided with the awl inclined-plane and the groove of screw thread, inside convergent.The socket core body is provided with valve belled part and the pipe belled part that combines with joint.Nut is threaded with joint.Hold-down ring places between socket core body and the nut.When using the valving connecting tube period of the day from 11 p.m. to 1 a.m of the present utility model, earlier nut and hold-down ring are passed in the end of pipe, then pipe is socketed in the pipe belled part of socket core body, fastening nut just can make pipe produce firm being connected with valving.
Valving of the present utility model has significant advantage, when practical application, and existing stronger join strength and excellent sealing performance, easy and simple to handle again, quick, greatly facilitate installment work.
