Description
Technical field
The utility model relates to a kind of control valve structure, especially relates to a kind of inlet and outlet control valve of solar water heater.
Background technique
Having greatly now, family has all loaded onto solar water heater.Use solar water heater, at first will wait the coolant-temperature gage arrival in the water tank to a certain degree just can use afterwards topped up with water in the water-heater water tank.In this process, just relate to a kind of control valve device, existing a kind of control valve device has valve body, valve nozzle base, the jam pot cover plug, intake-outlet, and the exhaustion spill pipe constitutes, jam pot cover is to have backguy to pass valve nozzle base to be connected with a floating drum beyond the Great Wall, utilize floating function to realize that by floating drum pulling jam pot cover plug to water Water Level Control on the water tank, it is unstable that this structure exists sealing, cause the shortcoming of control valve vibration during water inlet and outlet easily.
And the patent No. is 99257411.0 " solar water heater is water control valve up and down ", and it comprises valve body, valve nozzle base and jam pot cover plug, it is characterized in that being provided with on its valve nozzle base the flow channel structure of a jam pot cover plug guiding device and a buffering type.Described jam pot cover plug guiding device is a guiding element with floral disc sheet and guide sleeve, be fixed on the upper and lower end of valve nozzle base intake tunnel respectively, jam pot cover valve rod beyond the Great Wall passes the mesopore of floral disc sheet, the jam pot cover plug is seated in the guide sleeve, make the jam pot cover plug accurately up and down along the guide sleeve centerline direction, guide sleeve is by guide pin bushing tube and valve nozzle base stationary positioned; The flow channel structure of described buffering type is by the water inlet tap pipe, guide cylinder, the ceramic ring plate at valve nozzle base and two ends thereof and floral disc sheet are formed, and they are installed on the valve nozzle base, the sidewall of its guide pin bushing tube is provided with pod apertures, and the set fenestra in pod apertures and guide sleeve top is corresponding.This model utility water-outlet quantity when the water heater water level is low tends to not catch up with, and has brought certain trouble to use, and increases the guide pin bushing tube again make structure too complicated outside guide sleeve.
The model utility content
The utility model mainly is to solve above-mentioned technical problem, thereby provides a kind of simple in structure, and encapsulation is good, and water-outlet quantity is stable, especially still can guarantee the inlet and outlet control valve of solar water heater of stable water outlet when the water heater water level is low.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: the utility model is installed on the water-heater water tank, include ball float, connecting rod, valve plug and valve, described valve plug is installed in the valve, be connected with ball float by connecting rod, also comprise a control valve water tank that is installed on the water-heater water tank, this control valve water tank is divided into control valve upper water box and control valve lower header by thermal-protective coating, on described thermal-protective coating, be provided with the master, inferior two cover valvings, described master, inferior valving comprises the master, inferior valve, main, inferior connecting rod, main, inferior valve plug and master, inferior ball float, wherein main ball float stretches in the control valve upper water box by master connecting rod, and on master connecting rod, be provided with leading truck, described time ball float stretches in the control valve lower header by inferior connecting rod, is connected with turnover water pipe on described control valve lower header.
In the utility model, water-heater water tank and control valve water tank are to be interconnected, the position that is communicated with is at the control valve upper water box, the primary and secondary valve plug all can move up and down in the primary and secondary valve freely, when valve plug moves to the end of valve, be close to valve end, valve is thoroughly closed, because general master connecting rod is long, easy offset direction or fracture in the process that moves up and down, therefore add a leading truck, make master connecting rod move up and down, avoid fractureing and offset direction in certain location.When use is of the present utility model, water enters the control valve lower header by turnover water pipe, enters the control valve upper water box by valve then, in this process, because ball float has buoyancy in water, because of this time valve plug at first moves inferior valve closing under the effect of inferior ball float; Along with the rising of control valve upper water box water level, main ball float slowly rises, and under the effect of main ball float, main valve plug moves up to main valve is also thoroughly sealed on also can be slowly.In this process, the length of master connecting rod is suitable, makes the interior highest water level of control valve upper water box be lower than the position of overflow hole on the water-heater water tank.
As preferably, described primary and secondary valve plug constitutes by rubber seal and plastic interlayer, is equipped with some pod apertures on described primary and secondary valve, and all is stamped the ceramic plate circle on the primary and secondary valve.
Valve plug has one deck rubber seal one deck plastic interlayer repeatedly alternately to be formed by stacking, and the ceramic plate circle is housed on valve, when valve plug is drawn to the end of valve, the rubber seal face of valve plug side and the sidewall of valve are close to, the rubber seal face on valve plug top and the ceramic plate circle on the valve are close to, have dual water stop function like this, make that encapsulation of the present utility model is better; And the pod apertures that on described primary and secondary valve, is equipped with, it then is water is entered the control valve upper water box by the control valve lower header passage, can be opened in the place, neutral position of primary and secondary valve, can be when valve plug moves to valve end so that pod apertures is ineffective.As long as described ceramic plate circle is generally just passable by an end setting of control valve upper water box at valve.
As preferably, on described control valve lower header, be provided with breathing pipe, be provided with a bead and stop net at this breathing pipe end.
The density that is located at the bead in the breathing pipe pipe will be a bit larger tham water, in come-up, want simultaneously and breathing pipe can be blocked, when turnover water pipe is intake, because hydraulic pressure is bigger, the bead come-up is blocked breathing pipe, avoids water to run out of by breathing pipe, when stopping into water, bead sinks to no longer breathing pipe being blocked, because the existence that stops net is arranged, has also avoided bead to enter the control valve lower header simultaneously.In design, breathing pipe go out the height of water level that open height will be higher than water-heater water tank, avoid water to flow out by breathing pipe.
As preferably, stretch into control valve lower header place at described turnover water pipe and be provided with filter screen.
Filter screen is located at the outlet port of turnover water pipe, must pass through this layer filter screen when water enters the control valve lower header, prevents that dirt from passing through.
As preferably, on described master connecting rod, be provided with the lever regulated button of can regulate master connecting rod length.
Can regulate the length of master connecting rod by lever regulated button, make master connecting rod have suitable length, make when main valve bars up, the water level of water-heater water tank is lower than the position of overflow hole, when not establishing overflow hole on the water-heater water tank, the water level in the water-heater water tank will be lower than the outlet of the set breathing pipe of the utility model.
Therefore, in the utility model, by on water-heater water tank, connecting the control valve water tank, and in the control valve water tank, install two cover valvings, make to the utlity model has simple in structurely that encapsulation is good, water-outlet quantity is stable, especially still can guarantee the advantage of stable water outlet when the water heater water level is low.
