Abstract
The utility model relates to a noise eliminating flange type liquid operated water level controlling valve. The utility model is composed of a throttling component, a water pipe, a valve flap component, a valve body, etc., wherein an inner cavity of the valve body is divided into an upper pressure cavity and a lower pressure cavity by the valve flap component, the throttling component is arranged in the cavity of the valve body, the cavity is communicated with the upper pressure cavity through the throttling component, and the cavity is communicated with a small hole and the water pipe respectively. The utility model has the advantages of simple and reasonable structure, low cost and reliable operation. When the utility model is combined with a ball float valve, the utility model is suitable for a water feed pipeline of a water storage tank of a water supply system so as to perform the functions of an automatic switch.
Description
The utility model relates to a kind of control valve, particularly a kind of noise elimination flange-type altitude valve that surges.
Existing similar control valve structure is complicated, and cost is higher, moves also reliable inadequately.
The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part and provides a kind of simple and reasonable, and cost is lower, the noise elimination flange-type of the reliable in action altitude valve that surges.
The purpose of this utility model can reach by following measure; The utility model comprises water pipe, valve body, it is characterized in that; Also have orifice union, flap assembly, the flap assembly is divided into upward pressure chamber and downforce chamber to body cavity, also is provided with cavity in the valve body in addition, and orifice union is loaded in the cavity, and cavity communicates with the upward pressure chamber by orifice union, and communicates with aperture and water pipe respectively.
Fig. 1 is a structure sectional view of the present utility model;
Fig. 2 is the assembly structure figure of orifice union part.
The utility model is described in further detail below in conjunction with accompanying drawing (embodiment);
With reference to Fig. 1, Fig. 2, the utility model is made up of orifice union 3, water pipe 4, flap assembly 6, valve body 9 etc.Flap assembly 6 is divided into upward pressure chamber 5 and downforce chamber 7 to the inner chamber of valve body 9, in the cavity 2 of valve body 9 orifice union 3 is housed also in addition; Cavity 2 communicates with upward pressure chamber 5 by orifice union 3, and communicates with aperture 1 and water pipe 4 respectively.
When the water reservoir water level is in a high position, ball float rises with the water surface, and float valve is closed, and water pipe 4 water outlets are dammed, hydraulic pressure rising (by aperture 1 injection pressure) in the cavity 2, inject upward pressure chamber 5 by orifice union 3, the pressure of upper and lower pressure chamber is equated, and 6 times surface pressures of flap assembly are crossed the head piece expenditure and pressure, so flap moves downward stressed, promptly work the effect of damming of closing, the flap sealing surface is assembled with rubber seal, guarantees that sealing is reliable.When the water reservoir drawdown to certain altitude, ball float falls with the water surface, and float valve is opened, water pipe 4 water flowing ponds, hydraulic pressure prompt drop in the cavity 2 is to zero, the water in upward pressure chamber 5 flows away through orifice union 3, and pressure descends, and downforce chamber 7 hydraulic pressure are rubber film jack-up, driving flap assembly 6 rises, main pipe water in time replenishes water storage, till float valve is closed through valve flowing channel water outlet 8 water inlet pools.
The utility model has following advantage compared to existing technology: simple and reasonable, cost Low, reliable in action with ball-cock assembly or magnetic valve combination, is applicable to the feedwater of water system tank Pipeline plays the automatic switch effect.
