Abstract

The utility model discloses a valve which is arranged on a pipeline and is used for opening and closing the medium of the pipeline. The exterior of the non-magnetic columnar valve body is screwed with a magnetic hand ring. The valve core of the interior of the valve body is absorbed through moving the magnetic hand ring, and the opening and the closing are realized. The utility model overcomes the defects of the prior art that the hand wheel shaft and the valve body of the hand-operated valve are leaked, and has the advantages that the structure is simple; the use environment is improved; the leakage is not provided; the utility model is suitable for the pipelines for delivering the caustic, toxic and harmful gas mediums.

Description

Valve

The utility model relates to a kind of being installed on the pipeline in order to open and close the valve of pipeline medium, is particularly useful for carrying, preserve on the pipeline and equipment of corrosivity such as ammoniacal liquor, agricultural chemicals, chemical liquid and poisonous, evil medium.

In prior art, valve generally is made up of hand wheel shaft and handwheel that valve body, spool, drive spool open and close, seal by sealing material between hand wheel shaft and the valve body, after its deficiency was that valve uses a period of time, because of repeating to open and close, hand wheel shaft and valve seal place often produced leakage, not only need maintenance, repair constantly, and for mordant chemical medium and toxic gas befouling environment then, waste raw material, influence healthy.

The purpose of this utility model is to provide the manually-operated gate that does not produce leakage between a kind of handwheel and the valve body.

The purpose of this utility model is achieved in that valve comprises non magnetic column valve body, the spool that cooperates with valve body sealing surface and is enclosed within the valve body external enwergy moved axially and can drive its inner spool keying along valve body magnetic bracelet.The magnetic bracelet is made by whole magnetic steel material, or has magnet steel for a certain section along circumference.Valve body adopts nonmagnetic substance, as Cuprum alloy or engineering plastics, and magnetic thoroughly, the magnetic that makes the magnetic bracelet sees through valve body and holds steel spool in it, if mobile magnetic bracelet then can drive the valve body inner spool to move, the keying of realization valve.

Advantage of the present utility model and good effect are: (1) drives spool by the magnetic on the magnetic bracelet through valve body and moves, and whole valve body is in sealing, promotes spool by magnetic and opens, so can not produce leakage because of repeating to open and close.(2) reduce maintenance, improve working environment, save the medium raw material.

Fig. 1 is the valve first example structure sketch;

Fig. 2 is the valve second example structure sketch;

Fig. 3 is the plan view of Fig. 2.

Below in conjunction with accompanying drawing the utility model being made further detail describes:

Referring to Fig. 1, valve by column valve body 1, place the spool 2 in the valve body 1 and twist the magnetic bracelet 3 that is enclosed within on valve body 1 outer surface by screw thread and form.Spool 2 is free state and places in the valve body 1, and it is made up of the pipe of two sections variable cross sections, and its front end sealing has a plurality of flowing holes 4 on every side, and cooperates with 1 one-tenth cylndrical surface of valve body.On matching trim, can put O-ring seal, also can not put and guarantee by machining accuracy.Fig. 1 position is that valve is in closed condition, when turning magnetic bracelet 3 it is moved down, the spool 2 that is held by magnetic also can move down thereupon, the sealing surface and the pipeline that make the flowing hole 4 of spool 2 leave valve body 1 are connected, and the unlatching of realization valve, constantly repeat to turn up and down magnetic bracelet 3, can finish the keying of valve.Valve body 1 two ends adopt flange plate 5 to be connected with pipeline, also can adopt internal thread or outside thread to be connected with pipeline.

Referring to Fig. 2, spool adopts

steel ball

6, and 1 one-tenth ball face sealing of itself and valve body cooperates.

Referring to Fig. 3, steel ball 6 is valve body 1 center relatively, and magnetic bracelet 3 has only 1/4th sections to have magnet steel along circumference, so that steel ball 6 rotates with magnetic bracelet 3 and can be drawn onto different lateral place in the valve body 1.The closed hole of steel ball 4 sealings is partial to valve body 1 center.

Referring to Fig. 2, Fig. 3, this position is the valve closing state, this moment, steel ball 6 was not influenced by magnetic bracelet 3 and by conducting oneself with dignity the close encapsulation face, magnetic bracelet 3 is upwards turned dotted line position among Fig. 3, and (magnetic bracelet 3 can upwards continue to turn at this moment, also can freely turn round) at this place, then steel ball 6 is inhaled moving valve wall one side that arrives, and realizes opening.Rotate magnetic bracelet 3 again in this position, invar ball 6 is in eccentric position, and it is different to make steel ball 6 leave the distance of closed hole to the sidewall, and with closed hole between owe that to stitch size also different, accomplished the control of flow size.Goodbye Fig. 3, when having the magnet steel section to turn to apart from steel ball 6 highest distance positions on the magnetic bracelet 3 along circumference, valve openings maximum then, on the contrary minimum.Valve body 1 adopts transparent plastic material to make, and this kind valve mainly is applicable to the tap water water nozzle.
