Abstract

The utility model provides a time delaying closing control valve, which is composed of a main body and a floating body. The utility model is characterized in that the inner wall of the main body of the matching place of the main body and the floating body is provided with a water guiding groove, and the size of which is relative with the closing time of a control valve. The utility model effectively overcomes the defect that the time delaying function of the traditional control valve is bad, and the more reliable time delaying control function can be achieved, and the performance of the product is improved.

Description

The time-delay closing control valve

The utility model relates to the valve control device of cleaners and polishes, particularly a kind of time-delay closing control valve.

The control valve of traditional band time delay device, the control delay time is to realize by the aperture on the buoyancy aid.Because the aperture on the buoyancy aid is less, is very easily stopped up by dirt, thereby loses due delay function.Though and the time-delay valve of a new generation has been set up filter screen on the buoyancy aid aperture, filter Netease's incrustation, inconvenience is clear and coherent, also stops up easily.

The purpose of this utility model is to overcome above deficiency, provides a kind of simple in structure, the time-delay closing control valve of reliable performance.

The purpose of this utility model is achieved by the following scheme, and is made of main body and buoyancy aid, and the main body inner wall that is positioned at the cooperation place of main body and buoyancy aid is provided with gutter, and the shut-in time of the big or small control valve of gutter is relevant.

The utility model and prior art ratio have adopted relatively rationally and simple structure, have solved the existing deficiency of traditional time-delay control valve, have realized more reliable time-delay control function, have improved product performance.

Below in conjunction with accompanying drawing the utility model is illustrated:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the A-A sectional drawing of Fig. 1;

Fig. 3 is the partial enlarged drawing of Fig. 1.

As shown in Figure 1: this valve is made of main body 1, buoyancy aid 2, gutter 3, water intake 4, water outlet 5, wherein main body 1 is a General valve with buoyancy aid 2, key of the present utility model is to be provided with gutter 3 on the main body inner wall that cooperates of main body 1 and buoyancy aid 2, the magnitude relationship of gutter 3 is to the length of the time-delay closing time of control valve, and buoyancy aid 2 plays the effect of closing water outlet.

Claims

1, a kind of time-delay closing control valve is made of main body (1) and buoyancy aid (2), and it is characterized in that: the main body inner wall that is positioned at the cooperation place of main body (1) and buoyancy aid (2) is provided with gutter (3), and the size of gutter (3) is relevant with the shut-in time of control valve.
