Abstract

The utility model relates to a sprayer valve, comprising an inlet and an outlet. The inlet and the outlet are communicated by a hose; a hollow casing which is gradually bigger from one side to another side is arranged on the casing of the hose; a rolling body is arranged in the hollow casing. The utility model controls the speed and the flow rate of the fluid in the hose by the changement of the cross-section of the hose by changing the position in the hollow casing of the rolling body. No leaking phenomenon appears, for the rolling body moves outside the hose.

Description

Sprayer switch

The utility model relates to a kind of sprayer switch.

Chinese patent application numbers 91224954.4 discloses a kind of modified agricultural atomizer switch, and it is made up of switch case, cone rubber plug, driving lever, rubber sealing boot, bowl-type gas ket, bearing pin and push button.After this switch uses a period of time,, easily cause seepage because encapsulant is aging, the corrosion of distortion and metal part.

The sprayer switch that the purpose of this utility model is to overcome above-mentioned defective and then a kind of not easy to leak is provided.

The technical scheme that realizes the purpose of this utility model is; A kind of sprayer switch comprises import and outlet, and its key is that import and outlet are linked by flexible pipe, and empty by little gradually big housing in hose overcoat is equipped with, sky is provided with rolling element in the housing.

And described rolling element reaches and the contacted surface of shell of rolling element is provided with anti-skidding striped.

And described rolling element is a cylinder.

The utility model makes the cross-section variation of flexible pipe reach speed and the flow of control fluid in flexible pipe by changing rolling element empty position in housing.Because rolling element is movable outside flexible pipe, so the utility model ne-leakage phenomenon.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a structure chart of the present utility model;

Fig. 2 is the A-A cutaway view of Fig. 1;

Fig. 3 is installed on schematic diagram on the sprayer spray boom for the utility model.

As shown in Figure 1 and Figure 2, flexible pipe 2 one ends of the present utility model are that import 1, the other end are outlet 4, the flexible pipe 2 outer housings 3 that are set with, in the housing empty 5 along flexible pipe 2 directions by little gradually big, housing interior empty 5 is provided with can be along the cylinder 6 of flexible pipe 2 activities, and cylinder 6 reaches with cylinder 6 contacted housings 3 surfaces and is provided with anti-skidding striped 7.The utility model can all be manufactured with plastics.The also available spheroid of above-mentioned in addition cylinder 6 or with housing in empty 5 slide blocks that adapt replace.

The utility model can be located at and do the switch use on the sprayer.Existing sprayer is done repacking slightly also can use the utility model, recommend method is as follows: referring to Fig. 3, install front sleeve 12 and back sleeve 9 additional at handle 11 two ends of sprayer, cut off with blind plate 10,13 between sleeve 9,12 and the handle 11, front sleeve 12 and back sleeve 9 are communicated with rose and container respectively.Import 1 of the present utility model and outlet 4 are set on the cover mouth 14,8 of front sleeve 12 and back sleeve 9.Perhaps flexible pipe 2 is located in the handle 11, housing 3 is packed on the handle 11.In the utility model when work,, compression fluid flow through in the container successively front sleeve 12, import 1, outlet 4, back sleeve 9 are after the nozzle ejection.The cross-sectional area that the position of adjustable as required pitch circle cylinder 6 sky 5 in housing changes hose passages reaches control flow rate of fluid or flow.When cylinder 6 transfers to empty 5 smallest end positions in the housing, the cross-sectional area of hose passages (being subjected to the cylinder active position) is zero, and fluid can not pass through, and switch is in closed condition.Otherwise cylinder 6 transfers to when empty 5 maximums are held in the housing, and switch is in full-gear.

Claims (3)
