CN2450449Y - Low water pressure controlled valve - Google Patents

Abstract

The utility model provides a low water pressure controlled valve, which is composed of a float, a water level rubber ring, and a water level screw nut. The utility model is characterized in that two heads on the lower end of the water level rubber ring are respectively provided with a convex clack. The water level rubber ring is fixed on the float through the water level screw nut. The water level rubber ring also covers on the water level of a water outlet of a body. The characteristic that a valve can be automatically closed through low water pressure can be realized through an improved water pressure control valve. Consequently, the shortage that the existing valve with low water pressure can not be closed, which causes leakage is effectively solved.

Description

Low hydraulic controlled valve

The utility model relates to the hydraulic control device of cleaners and polishes, particularly a kind of low hydraulic controlled valve.

Traditional hydraulic control device complex structure, the water level cushion rubber is a plane type, the water outlet water level is processed into the boss shape.Because the water level cushion rubber area of this water-level control apparatus is bigger, is difficult to close low-pressure water, therefore occurs the low pressure water leakage phenomenon often, thereby caused unnecessary water resource waste.

The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of can be when water level be low the low hydraulic control device of automatic-closing valve.

The purpose of this utility model is achieved by the following scheme, constitute by buoyancy aid, water level cushion rubber and water level nut, two, lower end of wherein said water level cushion rubber is respectively equipped with protruding lobe, and the water level cushion rubber is fixed on the buoyancy aid by the water level nut, and is covered on the main body water outlet water level.

The utility model compared with prior art, it has increased the function of the automatic closing control valve of low hydraulic pressure except that having kept the peculiar function of former hydraulic controlled valve, have skill to solve the deficiency that existing valve can't be closed because of low hydraulic pressure.Make technical performance of the present utility model more perfect,

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 partial enlarged drawing of Fig. 1.

As shown in Figure 1 and Figure 2: constitute by water level nut 1, buoyancy aid 2, water outlet water level 3, protruding lobe 4, water level cushion rubber 5, water intake 7, water outlet 8.The control valve of above-mentioned formation is on the basis of existing hydraulic controlled valve, realizes by change water level cushion rubber 5.Concrete scheme is protruding distinguishing to be set respectively at two, lower end of water level cushion rubber 5 by water level nut 1 water level cushion rubber 5 was fixed on the buoyancy aid 24 (as shown in Figure 2), and is covered on the main body water outlet water level 3, thereby realizes the control of low hydraulic pressure.

Claims (1)

1, a kind of low hydraulic controlled valve, constitute by buoyancy aid (2), water level cushion rubber (5) and water level nut (1), it is characterized in that: two, lower end of said water level cushion rubber (5) is respectively equipped with a protruding lobe (4), water level cushion rubber (5) is fixed on the buoyancy aid (2) by water level nut (1), and is covered on the main body water outlet water level (3).
