Abstract

The utility model relates to a handle-free valve belonging to the valve for a pipe. The handle-free valve has a symmetrical structure, and joints 1 on both ends are respectively connected with a water inlet pipe and a water outlet pipe. The utility model is characterized in that an inner sleeve 2 is sheathed in a hand wheel 8; the upper and the lower parts of the inner sleeve 2 are respectively provided with a guide groove; a pin 6 is inserted in a valve plug 7, wherein, the outer end of which is fixed with sealing rings 9, 10 through nuts 3; both ends of the pin 6 are arranged in Z-shaped grooves in the inner wall of the hand wheel 8; the joints 1 on both ends of the valve are fixed by screw threads on both ends of the inner sleeve 2; sealing rings 4, 5 are arranged between the outer ring end head of the inner sleeve 2 and the hand wheel 8. The utility model has the advantages that one pipe type hand wheel can take the place of a water control function of a rotary part of the hand wheel of the existing valve handle, and the utility model has the characteristics of simple manufacture, time saving, material saving, sensitive water control, convenient installation and beautiful appearance; the utility model is an advanced device for arranging the pipe at a narrow place and indoors.

Description

Handle-free valve

One, affiliated technical field

The utility model belongs to the pipeline valve.

Two, technical background

Valve used on the water supply steam line is very general, is made up of the handle handwheel on valve body and the valve body, by rotation hand wheel, drives valve rod, valve core movement, opening or end with controlling plumbing fixtures.At present this class valve is all by exposing the outer handle control of valve body, and in narrow indoor of landform, then fitting operation is very inconvenient, has also influenced indoor decorative effect simultaneously as piping erection.

Three, summary of the invention

The purpose of this utility model provides a kind of may command valve that does not have handle, makes fitting operation simple, easy to use.

The utility model is achieved in that Handle-free valve is a symplex structure, the joint 1 at two ends is connected with the water-in and water-out pipeline respectively, it is characterized in that: interior cover 2 is sleeved in the handwheel 8, the interior cover 2 upper and lower guide grooves that have, pin 6 is inserted in the valve plug 7, is fixed with seal ring 9,10 in the outer end of valve plug 7 by nut 3; The two ends of pin 6 is installed in the Z type groove of handwheel 8 inwalls; The two ends of cover 2 in the joint 6 at valve two ends is fixed on by screw thread; Between the outer shroud termination of interior cover 2 and handwheel 8, seal ring 4,5 is installed.

Compare with existing valve, the beneficial effects of the utility model are: the control water function that only just can replace existing valve handle handwheel rotating part with a tubular type handwheel, it is not only manufactured simply, labor and material saving, and control bright and beautiful quick, easy for installation, aesthetic in appearance, be the sophisticated equipment of the narrow and indoor pipe laying of landform.

Five, embodiment

The internal diameter of handwheel 8 is Φ 36mm, the external diameter Φ 21mm of valve plug 7, and the valve two ends are communicated with pipeline respectively by screw thread.When handwheel 8 rotates counterclockwise, two valve plugs 7 of two pin 6 difference transmissions, the groove on handwheel 8 inwalls withstands until two valve plugs to the motion of the central position of handwheel 8, and at this moment valve plug 7 is opened, and water flows through in valve body, but normal water supply.The position represented as Fig. 1, when handwheel 8 was clockwise rotated, two valve plugs 7 were to the motion of valve two ends, and until the step hole that withstands joint 1, soon valve plug is closed and is cut off the water, and realizes the purpose of control water.
