Abstract
The utility model provides a loose joint valve which pertains to a rapid joint valve and solves the problems of difficult operation and slow speed during the connecting of a common valve. The loose joint valve comprises a valve body, a handle on the valve body and a joint pipe at the side of the valve body, wherein, a screw cap is nested at the outside of the joint pipe, the end of the joint pipe is provided with a flanging, a seal ring is arranged between the joint pipe and the screw cap, the joint pipe is fixed on the valve body, the screw cap can flex and slide on the joint pipe, the outer edge of the screw cap and the flanging of the joint pipe are at the same level when the screw cap is drawn back onto the joint pipe. The loose joint valve which uses the flex structure of the screw cap on the joint pipe can connect the pipes rapidly, simplifying the valve installation operation and improving the work efficiency. Meanwhile, the seal ring which is arranged between the joint pipe and the screw cap improves the sealing performance of the valve.
Description
Technical field
The utility model belongs to a kind of valve, particularly a kind of valve of connection fast that is used for.
Background technique
In existing valve, being connected between valve and pipe or the joint normally realizes by screw thread.In the valve installation process, between valve and the pipe joint is set, though help to install, troublesome poeration, and can increase the cost of pipeline.If but valve directly is connected with pipe, then need to rotate whole valve or pipe, particularly when the equal connecting tube period of the day from 11 p.m. to 1 a.m operation in the two ends of valve trouble very.Simultaneously, the end of pipe will embed in the valve when pipe was connected with common valve, and pipe must cut longlyer, and therefore when the two ends of valve all were connected with pipe, the workman was difficult to complete operation, and installation rate is very slow.
Summary of the invention
The purpose of this utility model is fitting operation trouble, the slow problem of installation rate in order to solve common valve and to connect, and the loose joint formula valve of the fast and favorable sealing property of a kind of installation rate is provided.
For achieving the above object, the utility model has adopted following technical proposal: this loose joint formula valve comprises the handle on valve body, the valve body and the adapter of valve body sidepiece, the outside socket nut of taking over, the end of adapter turns edge, and also is provided with seal ring between adapter and the nut.
Above-mentioned adapter and valve body are fixed together.Seal ring between adapter and the nut adopts O shape rubber seal usually.
In this loose joint formula valve, nut can be on taking over telescopic slide.The outer of nut is equal with the place that turns edge of adapter when the nut retraction.At first make the nut retraction during installation, valve just is easy to snap between the two tubes that is connected like this.Then, nut is twisted in the tube end that is connected get final product.Owing to be provided with seal ring between nut and the adapter, herein so can guarantee can not leak.
Compare with existing valve, the valve that the utility model provides has utilized the shrinking structure of nut on taking over, and can fast pipe be connected, and makes the fitting operation of valve convenient, has improved work efficiency.Simultaneously, the seal ring that is provided with between adapter and the nut has improved the sealability of this valve.
Description of drawings
Fig. 1 is the partial cutaway schematic of the loose joint formula valve that provides of the utility model.
Fig. 2 is loose joint formula valve that the utility model the provides structural drawing when being connected with pipe.
Embodiment
As shown in Figure 1, this loose joint formula valve comprises valve body 1, handle 2, adapter 4, nut 3 and seal ring 6.Valve body 1 adopts common structure, and handle 2 is used for the switching of control valve.The adapter 4 and the valve body 1 of valve body 1 sidepiece are fixed together.Take over 4 outer end and turn edge 5, turn edge 5 with take over 4 and be connected as a single entity.Nut 3 is socketed on takes over 4 outsides, turns edge 5 nut 3 can not to be broken away from take over 4.Seal ring 6 is arranged at nut 3 and takes between 4, and present embodiment adopts O type rubber seal 6.Nut 3 can taken over telescopic slide on 4.When nut 3 retractions, the outer of nut 3 with turn edge 5 equal.
This loose joint formula valve when mounted, at first nut 3 retractions make its outer and turn edge 5 equally, pipe 7 connecting ends that connected are placed take over 45 places that turn edge then, at last nut 2 are screwed into pipe 7 connecting ends and get final product.At this moment, this valve is in state shown in Figure 2.
Claims (4)
