Description

Universal diversion valve

Technical field

The present invention relates to valve technology field, especially relate to a kind of valve with a plurality of liquid outlets.

Background technique

In various water deliverys, oil transportation or air delivering pipeline, often need a plurality of branches be installed on main line, connect polytype pipe.Traditional method is to connect pipe fittings such as a threeway or four-way, mounted valve on branch line then on main line as required earlier.Like this, when not only installing operation various, detect trouble, and the cost height of high material consumption, pipeline.

For this reason, once the someone applied for a kind of branched flow divider (application number: patent CN02265292.2), it has solved, and the existing water outlet of existing diverter valve is few, each water outlet can't single channel the problem of control.After this valve is connected in the pipeline, after fluid enters from the feed liquor interface, by the liquid outlet outflow of each valve.The liquid outlet of each valve connects one road branch line, is independently controlled the break-make of its branch line by valve.Because the mode that adopted each valve independently to control, make that each branch line can independent conducting or close, be not affected each other.But when reality was used, the direction of each liquid outlet may be adjusted according to the different situations needs, and the liquid outlet of each valve in this scheme is fixed, therefore, can't regulate according to actual needs, be not very convenient just when in use.

Summary of the invention

The objective of the invention is at the problems referred to above, provide a kind of and have the multichannel liquid outlet, and the universal diversion valve that can regulate of the liquid outlet direction of each valve; The direction that has solved the existing in prior technology liquid outlet is fixed, the technical problem that can't regulate according to actual needs etc.

Another object of the present invention is at the problems referred to above, provides a kind of simple in structure, easy to implement, and universal diversion valve quickly and easily is installed; It is comparatively complicated to have solved the existing in prior technology structure, and it is very unreasonable to design, the technical problem of the big grade of assembling difficulty.

For achieving the above object, the present invention has adopted following technical proposal: this universal diversion valve, comprise a hollow valve pipe with a feed liquor interface, on the valve pipe, be provided with several valves, the liquid outlet of each valve is separate, it is characterized in that, the valve body of above-mentioned each valve all has a connecting body cylindraceous, the internal diameter of connecting body is slightly larger than the external diameter of valve pipe, the liquid entering hole of valve is opened on connecting body, each connecting body is socketed on the valve pipe mutually independently, and can rotate around the valve tube's axis, all has a through hole on the valve tube wall corresponding to each connecting body.

The present invention links to each other by a connecting body movable body between valve and the valve pipe.So when in use, connecting body just can rotate around the valve tube's axis, thereby the liquid outlet that can drive valve is done 360 rotational of spending around the valve pipe.So just can adjust the direction of liquid outlet according to the needs that use.

In order to prevent that connecting body from moving on the valve pipe, in above-mentioned universal diversion valve, have several limited ring grooves on the described valve pipe, be fixed with a limit body that inserts limited ring groove on each connecting body.

In above-mentioned universal diversion valve, be provided with some O RunddichtringOs between described connecting body and the valve pipe.

In above-mentioned universal diversion valve, described O RunddichtringO is located at each through hole both sides of valve pipe, and is provided with the circular groove of some placement O RunddichtringOs on the valve pipe.

In above-mentioned universal diversion valve, an end of described valve pipe is the feed liquor interface, and the other end is going out to be with on the liquid interface valve pipe box for going out liquid interface.Certainly the valve pipe here can be the structure of a sealing also, and does not set out liquid interface.The valve pipe box has the effect of sealing out liquid interface, and the while also provides possibility for the prolongation of valve pipe.

In above-mentioned universal diversion valve, described feed liquor interface and go out the liquid interface center line on same straight line, and valve pipe box and going out between the liquid interface by being threaded.Can realize connecting fast by screw thread, be convenient to assembling.

In above-mentioned universal diversion valve, also have a limited ring groove on the described valve pipe box, on the connecting body that connects valve and valve pipe box, be fixed with the limit body of the limited ring groove of an insertion valve pipe box.

In above-mentioned universal diversion valve, the feed liquor interface end of described valve pipe is with a trim.

In above-mentioned universal diversion valve, be with 2～4 valves on the described valve pipe side by side.

In above-mentioned universal diversion valve, the type of described valve is ball valve or stop valve or gate valve.

Compared with prior art, the advantage of universal diversion valve is:

1, adopts a connecting body movable body to link to each other between valve and the valve pipe, make the liquid outlet of each valve to adapt to the needs of different behaviours in service independently around the rotation of valve tube's axis.

2, each valve is independently controlled, can independent conducting or close, be not affected each other, and use very flexible, of many uses.

3, good airproof performance, employing is threaded, and is convenient to quick mounting, and maintenance procedure is simplified greatly.
