Abstract

The utility model discloses a float auto-control valve, in particular to an auto-control valve arranged on a solar water heater, comprising a valve body, a conducting pipe, and a float chamber, wherein, the valve body is composed of a valve seat, a valve core, a conducting wire, a water inlet and outlet, and an O-shaped sealing ring arranged on the valve core, and the valve core is a one-way valve. When the utility model fills water in a container, utilizing the buoyancy of water and inlet pressure to cause the valve core to tightly press the O-shaped sealing ring, and the goal of sealing closing is achieved. When the water in the container is used, the goal of opening water flow is achieved through the depression of water level and the self gravitation of the valve core. The utility model has the advantages of simple structure, convenient use, easy installation, convenient maintenance, flexible opening and closing action, and good sealing performance. Because water inlet channel and outlet channel can use one pipe together, the pipe material is saved, and the installation and maintenance cost is reduced.

Description

Float auto-control valve

The utility model relates to a kind of float autocontrol valve, especially is installed in the autocontrol valve on the solar energy water-heater.

Present domestic lavatory flushometer, filling of containers such as solar energy water-heater, most of float valve that adopts is controlled, utilize the rising of water level and descend and drive rising and falling of ball float, by lever buoyancy is amplified, kill the water intake of water inlet, greatly often cause the phenomenon that is not closed completely to take place owing to transmit ineffective intake pressure.A kind of float automatic on/off valve is disclosed in No. 89219523.1 patent applications of Chinese patent, this automatic on/off valve generally can reach the purpose of use, and sealability is also not bad, but shortcoming be open nimble inadequately, especially occur the corrosion dirt in the valve pocket, in time, has and opens ineffective defect and take place; Turnover water pipe need overhead have certain altitude when this kind valve was installed, and gave to install and use and made troubles.

It is nimble that the purpose of this utility model provides a kind of open and close, good seal performance, and antifreeze, blowdown convenience, inlet channel, water outlet use the float autocontrol valve of a pipe jointly.

Technical solution of the present utility model is: a kind of float autocontrol valve, and it comprises valve body 1, conduit 2, float chamber 3, it is characterized in that: valve body 1 is made up of valve seat 4, spool 5, lead 6, intake-outlet 7 and zero RunddichtringO 8 that is positioned at spool 5 tops; Valve seat 4 is located at valve body 1 bottom, and the valve seat lower end has antifreeze, blowdown screw 17 is twisted dead with bolt 18 when valve uses; Spool 5 is an one-way valve, and spool 5 outer walls and valve seat 4 inwalls leave the slit, and the spool top has into water circular hole 9, circular hole has zero RunddichtringO 11, and valve core cavity is provided with control water polo 10, has spring 12 to support under the control water polo, spring is fixed on the spring collar 14, is pressed with pad 13 on the spring collar; Lead 6 one ends are fixed on spool 5 tops, and the other end links to each other with float chamber float 15 along conduit 2.

The center line of the valve body import and export 7 in the technical solution of the present utility model and the center line of valve body 1 are perpendicular, and the intake-outlet 7 of valve body can be shared, and the turnover water channel 19 that links to each other with its intake-outlet can use a pipe jointly.

Spool 5, anti-freezing and pollution-discharging bolt 18 in the technical solution of the present utility model are made of copper, and control water polo 10 is made by glass, plastics etc., and lead 6 is made by anti-rust metal silk or nylon rope.

The one-way valve of spool 5 in the technical solution of the present utility model for having conical head hexagonal prism profile.

The advantage of a kind of float autocontrol valve of the present utility model is: 1. simple in structure, install and use easy to maintenancely, and prevented the generation of prosperous excessive phenomenon when the container water-filling, saved water; 2. open, closing motion is flexible, good seal performance is not subjected to the influence of intake pressure, the sealability of the big valve of intake pressure can be better; 3. inlet channel, water outlet use a pipe jointly, can save tubing 45%, have saved installation fee and maintenance expenses simultaneously.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

Fig. 1 is the elevation cross-sectional view of a kind of float autocontrol valve of the utility model.

Fig. 2 is the working principle schematic representation of a kind of float autocontrol valve of the utility model.

The 1-valve body, 2-conduit, 3-float chamber, 4-valve seat, the 5-spool, 6-lead, 7-intake-outlet, 8-zero RunddichtringO, the 9-circular hole of intaking, 10-is controlled water polo, 11-zero RunddichtringO, 12-spring, the 13-pad, 14-spring collar, 15-float, 16-pore, 17-anti-freezing and pollution-discharging screw, the 18-bolt, 19-passes in and out water channel, 20-water supply valve door, the 21-solar energy water-heater, 22-water valve, 23-shower nozzle.

As Fig. 1, shown in Figure 2, when solar energy water-heater's water-filling, at first water supply valve door 20 is opened, water enters valve body 1 inner chamber along turnover water channel 19 by autocontrol valve intake-outlet 7, flow to float chamber 3 by conduit 2, water flows to solar energy water-heater 21 by intake-outlet 7 along turnover water channel 19 simultaneously, because the continuous rising of float chamber 3 and solar energy water-heater's 21 water levels makes float 15 float (gas of float 15 rising extruding float chambers 3 is discharged from pore 16) gradually, and affect lead 6 that spool 5 is mentioned, when mentioning certain altitude, water flows into valve core cavity by the spool bottom will control water polo 10 jack-up, fasten mutually with zero RunddichtringO 11 in the spool and to block, spool 5 by float 15 pull up and water flow pressure rises gradually, be full of whole solar energy water-heater 21 until water, when float 15 rises to the water level predetermined altitude, spool 5 conical head contact with zero RunddichtringO 8 and fasten, automatic-closing valve, when continuing water-filling, it is more firm that spool 5 makes spool 5 by the pressure of water conical head and zero RunddichtringO 8 are pressed mutually, thereby sealability is better.

As Fig. 1, shown in Figure 2, when the hot water that uses the solar energy water-heater carries out shower, earlier water supply valve door 20 is closed, again hot-water valve 22 is opened, owing to be subjected to the pressure of solar energy water-heater's water level, the water of turnover water channel 19 begins to flow out from shower nozzle 23, simultaneously water flows to turnover water channel 19 from autocontrol valve intake-outlet 7, because glassware for drinking water has certain pressure, water flows into spools 5 from spool circular hole 9 and will control water polo 10 and wash open, water flows into spool 5 inner chambers, return from spool 5 bottoms, along the slit flow of 4 of spool hexagonal prism and valve seats to valve body intake-outlet 7, turnover water channel 19, cause drawdown, float 15 descends along with the decline of water level, add upper valve core 5 from gravity, make spool 5 break away from zero RunddichtringO 8, whole autocontrol valve is open-minded, uses until exhausted until hot water.
