Description
Technical field
The utility model relates to a kind of water mixing valve with two single switches, is suitable for electric water heater or solar water heater and uses.
Background technique
At present on domestic and international market, be applied to the common cold-hot water mixing constant temperature valve in electric water heater or solar water heater, its switch of the overwhelming majority is arranged on mixing water waterexit end, its disadvantage is that water-holding quantity is many and with the high pressure of former watering in the valve closing rear valve body, because of the icing very easily freezing valve of cold, cause waste, even accident winter, but also must install one-way valve additional at water intake, avoid going here and there water.There is in the market a kind of thermostatic valve: one end is biswitch spool, and the other end installs constant temperature valve core, but also have its narrow limitation, i.e. complex structure, cost is high, fragile, and flow is little, particularly more inconvenient under the occasion for the large flow of need.In addition, one of the utility model designer's the patent (patent No.: 200620000136.3 and 200620161827.1), used the fluidic element in existing fluidics to be applied in water mixing valve, there is certain counterflow-preventing and supercharging constant temperature effect, but complicated because of valve core structure, flow is little and limited.
The valve body of above-mentioned numerous mixing valves adopts casting technique manufacture more in addition, and cost is high, and processing technology is complicated.
Model utility content
The utility model provides a kind of water mixing valve with two single switches, is suitable for electric water heater or solar water heater and uses.Due to before two single switch spools are arranged at mixed valve core, after valve closing, after mixed valve core not water (water outlet down) even if or water (water outlet upward) but without the high pressure of water supply network, there is antifreeze function in winter, there is flow large, particularly more convenient practicality under the occasion for the large flow of need simultaneously.The utility model has adopted again the supercharging spool of existing fluidics in addition, makes it the more convenient practicality of the utility model.The utility model has adopted die casting or Shooting Technique to above-mentioned valve body manufacture in addition, and technique is simple, saves material, and makes it cost.
The utility model improves the water mixing valve on market, and its technological scheme is:
A kind of water mixing valve with two single switches, it comprises valve body, single switch spool 3, constant temperature valve core 4 and handwheel, it is characterized in that: described valve body comprises main valve body 1 and is arranged on two valve body end caps 2 in main valve body 1 two ends, each valve body end cap 2 is installed a single switch spool 3, to control keying and the flow of hot and cold water water inlet, each valve body end cap 2 is by water inlet bolt 5 and seal ring and main valve body 1 fixing seal, and can be connected with outside intake tunnel, between valve body end cap 2 and main valve body 1, end bracket enclosed circle 6 is set, so that enter the water of valve body, can between main valve body 1 and valve body end cap 2, not ooze out, the centre of main valve body 1 is provided with the mixing chamber M that spool is installed, in mixing chamber M, be provided with two water inlet P, Q, the cold water entering with main valve body 1 two ends respectively or hot water are connected, the bottom of mixing chamber M is provided with water outlet N, constant temperature valve core 4 is arranged in mixing chamber M, the hot and cold water being entered by main valve body 1 two ends mixes constant temperature through constant temperature valve core 4 and through water outlet N, flows out.
The cold and hot water inlet at the two ends of above-mentioned valve is after passing through single switch spool separately, before entering mixing chamber M by two water inlet P, Q, it in valve body therebetween, can be unlimited cavity, but will cause that like this water is too much, very easily cause bursting by freezing in winter valve body, in order to eliminate this defect, the utility model proposes following solution:
Mixing chamber M in the middle of main valve body 1 to the arranged outside of the water inlet direction at two ends two sections of extra heavy pipes, in every section of extra heavy pipe, comprise a water inlet (P or Q), described each valve body end cap 2 is in the plane of the mixing chamber M direction towards main valve body 1, that is install in the base plane of single switch spool 3 one section of tubule that comprises osculum is set, this tubule inserts in above-mentioned extra heavy pipe, connection O type circle 7 sealings that arranged by tubule periphery, because water in pipe is few, are difficult for damaging valve because freezing.
The utility model is done further improvement to mixing valve on above-mentioned basis, the jet spool 8 forming with fluidic element in the mixing chamber M that constant temperature valve core 4 is installed substitutes it, can become large flow, antifreeze, counterflow-preventing string water, and the horizontal type jet mixing valve with certain temperature stabilization effect, the fluidic element in prior art comprises installs adjusting thimble 8-1, Adjusting bolt Adjusting screw 8-2, nozzle 8-3, trunnion and diffusing tube 8-4, thimble seal ring 8-5, sealed nozzle circle 8-6, trunnion seal ring 8-7 and the handwheel connecting successively.
If cold water pressure is during much larger than heat hydraulic pressure, allowing cold water pass through nozzle (8-3) penetrates, hot water enters from suction chamber R, when single switch open at two ends and be adjusted to after a certain temperature, if the cold water pressure causing because of tap water pipe network changes, cause cold water influx to change, also instant synchronous variation of hot water intake, substantially maintain former hot and cold water water inlet ratio, thereby now, can maintain output temperature constant or change very little (vice versa).
Rotate handwheel to regulate thimble (8-1) to move up and down, can change the distance regulating between thimble (8-1) and nozzle (8-3) aperture, to change the flow velocity of high-pressure water flow, thereby change the vacuum magnitude of suction chamber R, that is change to suck the hot water water yield number, as the fine setting to the different initial temperature of hot and cold water, use.
Total the above, the utility model is simple in structure, flow is large, manufacturing process is simple, cost is low, and has low temperature antifreeze function.
