Abstract
The utility model relates to an improved backwater automatic control float valve type auxiliary water tank. The utility model is characterized in that a valve which is a direct valve is connected with a cold water inlet; a water outlet of the direct valve is directly communicated with a main water tank, the cold water of a tapping pipe is directly injected into the main water tank of a solar water heater by the direct valve; a turn-off handle of the direct valve is directly and fixedly connected with a ball rod of a float ball. A backwater port which is communicated with the main water tank is also arranged in a tank body. When the auxiliary water tank is full of backwater cold water, the float ball can be upwards floated, and the handle of the direct valve is made to turned off the direct valve. The utility model can improve the properties of water supply states of the main water tank, the utility model does not have the problems of old type ball valves that rubber sealing plugs are aged and the deformed, the ball valves do not work when the water is closed, the water leakage is serious, etc.
Description
The utility model relates to a kind of secondary waterbox design technology that is used for solar water heater water tank, and particularly a kind of cold water of running water pipe that allows directly leads to the secondary water tank of the follow-on backwater automatic control float valve type of solar water heater (master) water tank (comprising vertical water tank or horizontal water tank).
The ball-cock assembly that adopts in prior solar water heater main water box (comprising vertical water tank or horizontal water tank) the secondary water tank that it disposed all is with the same structure technology of the used ball-cock assembly of apartment, general residential district roof water tower, adopt existing ball valve, time one is of a specified duration, there is the aging distortion of rubber packing plug, Guan Shui is not tight, problems such as service life is short, particularly existing secondary water tank is after allowing cold water in the running water pipe enter secondary water tank through ball-cock assembly, delivery port by secondary water tank flows in the main water box (vertical water tank or horizontal water tank) again, because of secondary water tank cavity communicates with ambient atmosphere, often cause hydraulic pressure to reduce (do not have the hydraulic pressure of running water pipe big), unavoidable sometimes the existence occurs the unfavorable situation of main water box water supply state.
The purpose of this utility model is to design a kind of secondary water tank of modified that adopts new-type ball-cock assembly, it can allow the bigger cold water of hydraulic pressure that comes from running water pipe flow directly into main water box, automatically shut down valve again after water pot is full, the aging distortion of no rubber packing plug, the anxiety that Guan Shui is not tight has effects such as designs simplification long service life.
The utility model is realized with following technical scheme: it is to improve to form on the technical foundation of the secondary water tank that is provided in existing solar water heater main water box (comprising horizontal water tank or existing vertical water tank).It comprises casing, case lid, cold water inlet (joining) with running water pipe, valve, ball float (playing the valve switch effect), it is characterized in that the valve that joins with cold water inlet is straight valve (or cold water tap), and the delivery port of straight valve directly joins with main water box and is communicated with, and can the main water box of solar water heater will directly be injected by straight valve from the higher pressure cold water of running water pipe, the club of described ball float directly is fixedly connected on the switch knob of straight valve, also offer the refluxing opening that is connected with main water box in the casing, when (cold) water pot that enters from refluxing opening is expired secondary water tank, can make ball float upwards lift (floating) thereby and drive club together with the switch knob of straight valve also upwards swing lift Shuttoff Valve (straight valve), when in the secondary water tank when anhydrous, the ball float landing can be injected cold water to main water box by Open valve.
The utility model is owing to adopt above-mentioned valve mechanism, can make the cold water from running water pipe directly inject main water box by straight valve (or cold water tap), can keep the intake pressure the same when not only supplying water with running water pipe, thereby greatly improved the water supply state performance of main water box, and the utility model adopts straight valve (or cold water tap) can effectively avoid old-fashioned ball-cock assembly that the aging distortion of rubber packing plug is arranged like that, Guan Shui is not tight, problems such as water clock is serious occur, it is stable to have serviceability, advantages such as long service life.
Below in conjunction with accompanying drawing embodiment concrete structure principle of the present utility model is described in further detail:
Fig. 1 is a kind of structural representation of the secondary water tank of the utility model.
Fig. 2 is the A-A direction view of Fig. 1.
1～case (shell) body wherein, 2～case lid (loam cake), 3～ball float, 4～club (fixedlying connected) with straight valve handle, 5～(straight valve) delivery ports, 6～straight valve handle, 7～straight valve (or cold water tap), 8～cold water inlet (joining) with running water pipe, 9～refluxing opening (can join with the following circulation port of main water box and be communicated with).
With reference to accompanying drawing as can be known, the utility model also can have following technical characterictic when specific design is made:
One, the also available cold water tap of described valve replaces straight valve (figure slightly), and the delivery port of cold water tap also directly joins with main water box and is communicated with, and can will directly inject the main water box (figure slightly) of solar water heater by cold water tap from the higher pressure cold water of running water pipe.
Two, no matter be straight valve or cold water tap, the structure of its spool part all can adopt the structure of ceramic seal chip, can greatly improve spool parts durability like this, increase the service life and simplify switch motion (ball float need only turn over certain angle and can finish switch motion together with turn-offing handle).
Three, be opened in the bottom that refluxing opening 9 in the secondary water tank is provided in a side of casing 1, it can be join with the following circulation port of solar water heater main water box and be communicated with (can from circulation port down branch out a water pipe join with the refluxing opening of secondary water tank be communicated with).
