Abstract
The utility model relates to a cold and hot water mixing and adjusting valve for an electric water heater. The existing mixing and adjusting valve is composed of a shell, a valve core and a handle. The valve core is a hollow body. A cold and a hot slotted holes and an outlet cross hole arranged on the valve core are corresponding to a cold and a hot water inlets and a warm water outlet arranged on the shell. The utility model is additionally arranged a cold input interface which is communicated with the inlet of the tap water through an inclined hole and a moon-shaped slot arranged on the valve core surface on the shell. One end of the cold input interface is communicated with the cold water inlet, and the other end of the cold input interface is connected with the cold end of the water heater to control the water inflow of the water heater. The utility model has simple structure, and convenient operation. The switches of the water output, the water temperature and the water inflow of the water heater can be simultaneously controlled only through pushing, pulling and rotating the handle.
Description
The utility model relates to a kind of multichannel valve, and particularly a kind of electric water heater hot and cold water mixes transfers valve.
Disclosed a kind of triple valve in CN86205714U, its structure is by housing, spool and handle are formed, spool is a conulite, have cold on the cone position, hot slotted hole, hollow part is an exit orifice, all the time communicate with the outlet passage of housing, cold, hot slotted hole cold corresponding on the housing, hot water intake, but certain dislocation is arranged, when cold slotted hole was alignd with cold water intake, hot slotted hole just touched mutually with hot water intake, instead then too, rotatable handle can cause these big those little or these little those big situations of cold and hot water intake conducting cross section during work, influences the variation of water-exit temperature.But this device deficiency is that flow is uncontrollable, and use also needs the adapted inlet valve on water heater.
The purpose of this utility model is that a kind of water-outlet quantity of design and water temperature are adjustable, and the hot and cold water of may command electric water heater water inlet mixes and transfers valve again simultaneously.
Task of the present utility model is achieved in that and is equipped with a cold output interface on the housing, and cold output interface is through inclined hole and be located at communicating with running water inlet behind the shape groove by the moon of spool face, and the one end communicates with cold water intake, and the other end is to the cold junction of water heater.During use, to drawing handle, can change the conducting cross section of moon shape groove and inclined hole toward poppet shaft, the water yield that influence enters water heater has also changed hot and cold water intake conducting cross section simultaneously, influences its water-outlet quantity, and rotatable handle can adjust the temperature that needs water of fitting.
The utlity model has simple in structurely, easy to use, its outstanding feature is as long as a handling handle, can control the switch of water-outlet quantity, water temperature and water heater water inlet simultaneously.
Below in conjunction with concrete legend the utility model is described further:
Fig. 1: the water heater hot and cold water mixes transfers the valve longitudinal sectional view.
Fig. 2: the A-A section,
Fig. 3: the B-B section,
Fig. 4: the C-C section,
Example one: the hot and cold water that is used for open type electric water heater mixes transfers valve.
With reference to figure one, this device by housing 14, spool 1 and handle 18 three-major-items form, spool 1 is hollow body, which is provided with hot and cold slotted hole 5,10 and translot hole 12, with the hot and cold water intake of establishing on the housing 14 8 ', 20 and warm water export 13 corresponding.Spool 1 surface is provided with shape groove 3 in January.With the axial motion of spool 1, controlling the running water inlet 9 on the housing 14 and the conducting and the disconnection of inclined hole 6, inclined hole 6 communicates with cold delivery outlet 8, and cold delivery outlet 8 one ends lead to the water heater cold junction, and the other end communicates with cold water intake 8 through throttling lid 7.Also be provided with a micropore 11 that communicates with hot water intake 20 on the spool 1, the air pressure of water heater liner is identical with barometric pressure when being used to guarantee to heat, and wherein warm water outlet 13 is for opening wide outlet.Can see also that from drawing the two ends of spool 1 are respectively equipped with pressure leather cup 2,15, for whole stroke sealing is used; Locating slot 16 is controlled by non-magnetic shim, is used to limit the axial displacement and the angle of swing of spool.
Example two: the hot and cold water that is used for closed electrical water heater mixes transfers valve.
The inner bag of closed electrical water heater is through special processing, can bear bigger pressure, and in use, the pressure of inner bag and the hydraulic pressure of tap water normal maintenance is equal to state, thus hot and cold water intake when cross section equally, flow is the same.With reference to figure one, between cold delivery outlet 8 and the cold water intake 8 ', do not establish throttling lid 7, and do not establish the micropore 11 that communicates with hot water intake 20 on the spool 1 yet.
The utility model is abandoned the threaded adjusting mode and is changed the valve opening cross section, so machinery is required to reduce relatively, the molding and forming of available nylon 1010 material, simplified processing process, save metal, increase the service life, reduce cost, and as long as in a secondary mould, do slightly to change the mixed accent valve that to accomplish two kinds of different types, to adapt to the electric water heater demand of various different water storage patterns.
