Abstract
The utility model discloses a hydraulic automatic stop valve. The valve has a valve body with water inlet in the lower part, water outlet in the lower part and valve rod guide cylinder in the upper part, and valve core inside the valve body and with hollow sealing structure, valve rod in the upper part and conic lower part, and when the valve core is in the lower limit position, the conic body is sealed to the inner port of the outlet to cut off the water flow in the outlet. Realize automatic damming, the utility model discloses simple structure is applicable to water filter's back flush unit.
Description
The utility model relates to a kind of waterpower automatic stop valve, is used for water filtration machine back purge system.
Industrial and mineral and small-sized engineering of water treatment use gravity valveless filter more at present, because this filter tank moves automatically, simple in structure, stable working is reliable, so be used widely, but water consumption is more when backwash, promptly the water of intake pipe can not block when backwash, directly enter syphon tube by the next current of intake pipe and enter sewerage, cause waste.
The purpose of this utility model is to design a kind of waterpower automatic stop valve of being made up of hollow closed spool and valve body that cuts off filter tank intake pipe entery and delivery port voluntarily for overcoming above-mentioned deficiency.
The utility model content: a kind of waterpower automatic stop valve, comprise valve body and spool, it is characterized in that: the valve body downside is established water intake, and valve body lower end sets out the mouth of a river, and the valve body upper end is provided with the guide cylinder of valve rod; The spool that is loaded in the valve body is made as hollow enclosed construction, and valve rod is established in the spool upper end, and the spool lower end is designed to cone, when spool is positioned at the lower end limit position, and the inner port tight engagement of described cone and water outlet, the current of cut-out entery and delivery port;
The utility model advantage:
1. the spool of waterpower automatic stop valve is hollow enclosed construction, because the intake pipe flow velocity in filter tank is 0.6M/S, under buoyancy function, spool is floating to valve body top, and pending water flows out for using through filter box through the waterpower automatic stop valve again; When backwash, because strong siphonage makes water oppositely flow into the siphon asending pipe, flow velocity increases sharply to 3M/S, at this moment, form very big negative pressure, make spool move on to valve body lower portion in moment in waterpower automatic stop valve outlet port, cut off current, this moment, the water on waterpower automatic stop valve top can overflow to other Rose Box filtration through distributing chute, had avoided the waste of former water, after backwash finishes, spool is floating automatically to valve body top, continues to filter.
2. the utility model is simple in structure, makes easily, and cost is lower.
Description of drawings:
Fig. 1 is the utility model schematic representation (analysing and observe);
Fig. 2 is a filter back purge system schematic representation;
Fig. 3 is filter back purge system hydraulic transmission principle figure.
Further specify the utility model below in conjunction with drawings and Examples.
Please referring to Fig. 1, the waterpower automatic stop valve is made of valve body 1 and spool 2, and the valve body downside is provided with water intake 5, and valve body lower end is provided with water outlet 7, the valve body upper end is provided with the guide cylinder 4 of valve rod, spool is the enclosed construction of hollow, and the valve body upper end is welded with valve rod 3, and spool can move in valve body, valve rod moves back and forth in guide cylinder simultaneously, the lower end of spool is designed to cone 6, and described cone can closely contact with the inner end of valve body water outlet, to cut off current.The waterpower automatic stop valve is loaded on the intake pipe of water filtration machine back purge system and near Rose Box ingress (Fig. 2, Fig. 3).Its working procedure is: the water that contains certain turbidity is introduced by intake pipe 9, flow into the bottom of siphon asending pipe 17 through waterpower automatic stop valve 11, flow into Rose Box 13 again, be provided with strip filtering board in the Rose Box, filtrate, the water that has filtered enters water storage box 16 and discharges through water outlet 15, for using, when filter material layer trapped substance in the Rose Box arrives to a certain degree more, it is big that resistance becomes, water is risen by syphon tube, when water level reaches the mouth of pipe of auxiliary siphon tube 21, water just sharply falls from auxiliary siphon tube and siphonal air is taken away, form vacuum, siphon asending pipe middle water level continues to rise, at this moment siphon falling tube 19 also sucts the water of 22 li of the closed trapped wells of Waste Valves to certain altitude, when the water that rises in water in the siphon asending pipe and the siphon falling tube converges, promptly form siphon, on auxiliary siphon tube, be provided with the box 20 of bleeding by the manufacturing of water jet device principle, it can make the air in the syphon tube system extract out rapidly, on the siphon falling tube, establish a backwash modulating valve 18, this valve is a throttle valve, and regulating its opening degree is the may command back washing strength.Water in the water storage box flows into Rose Box from bottom to top and cleans automatically, the water that washed flows to trapped well 22 and enters sewerage by the road through the siphon asending pipe together with trapped substance, trapped well is made as enclosed construction and is provided with and leads to outdoor outlet pipe 14, solved the room air pollution problem, siphon destructive bucket 12 is located at the top of water storage box 16, and should be lower than water outlet 20mm, fill siphon destructive bucket 12 earlier when guaranteeing that water storage tank water level goes up after the backwash and arrive water outlet 15 again, siphon destructing tube is provided with backwashing time regulator 10, described regulator is a throttle valve, regulate the time of the aperture of throttle valve with regard to the may command backwash, below the water tank middle water level drops to siphon destructive bucket edge mouth and during the water extinction of siphon destructing tube in will struggling against, air is just entered by siphon destructing tube in a large number, destroyed siphon, backwash stops, the waterpower automatic stop valve resets simultaneously, former water is through intake pipe, the waterpower automatic stop valve, the siphon asending pipe flows to Rose Box, filter and begin again, owing to adorn a hollow spool in the valve body of waterpower automatic stop valve, under the buoyancy of water effect spool is floated during filtration, former water flows into the siphon asending pipe through the waterpower automatic stop valve, Rose Box is to water storage box; When backwash, because strong siphonage, form very big negative pressure in waterpower automatic stop valve outlet port, the bottom that spool moment just moves to valve body cuts off pipeline, and former water overflows to other Rose Box through distributing chute and filters, and 8 is totally three of liquid level tubes among the figure.
