Description

Water heater cold, hot two-purpose thermostat

Technical field

The utility model relates to a kind of liquid flow-conditioning, especially a kind of water heater cold, hot two-purpose thermostat.

Background technique

Gas water-heater commonly used is at present controlled the hot water temperature of flowing out water heater by regulating flame size with the cold water flow size that adjusting enters water heater mostly.This method for regulating temperature needs the inside and outside cooperation in bathroom to finish, and seems very inconvenient.Chinese patent ZL992160278 has proposed a kind of " water heater cold, hot two-purpose water nozzle ", its main structure feature is to depress at two pasted valve types to be separated out preceding mixing chamber in portion's inner chamber, back hot water inlet tube chamber, valve seat top has respectively corresponding to hot water inlet tube chamber two side outer rim place, back that cold water enters the hole and cold water portals, have cold water through hole and tap hole corresponding to both sides, preceding mixing chamber rear portion, the spool lower surface of being located by valve bonnet seal offers garden arc connectivity slot.Flow, proportioning that the hole that it is communicated with by garden arc connectivity slot is regulated the hot water or cold water, and then regulate water temperature.The dual-purpose water nozzle of this structure itself does not possess constant temperature device, adds that each hole arrangement is asymmetric, very easily causes water clock when hydraulic pressure is high, and energy waste is big, does not have obvious progress with prior art, applies the restriction that is subjected to a certain degree.

Summary of the invention

The purpose of this utility model just is to overcome above-mentioned the deficiencies in the prior art part, and it is simpler to propose a kind of operation, and layout is more reasonable, processing and fabricating is more perfect, can directly set cold water or constant-temperature hot water, plug and play has a kind of water heater cold, hot two-purpose thermostat of energy-and time-economizing.

The purpose of this utility model adopts following technical proposal to realize: having into cold water outlet, going out in the valve body inner chamber of cold water outlet, hot water inlet and dewatering outlet, be separated out water-inlet cavity, water chamber and the mixing chamber of mutual isolation accordingly, above-mentioned hot water inlet is connected on the mixing chamber with the dewatering outlet that has valve, the upper surface corresponding part of described valve body has the water inlet, osculum and tap hole, cylindrical body spool by valve bonnet seal and location is set on it, and this spool lower surface offers a circular arc connectivity slot.Described valve body is cuboid shape, its place, each chamber, bottom is provided with cold water outlet respectively, go out the side that dewatering outlet that cold water outlet and hot water inlet one have valve is positioned at hot water intake, the joint of the partitioning wall of water-inlet cavity, water chamber and mixing chamber is 14, and the dewatering outlet 7 that has valve is located on the sidewall of mixing chamber 6.The upper surface of described valve body corresponds to place, each chamber and has water inlet 8 respectively, osculum 9 and tap hole 10, and 9 directions have a dovetail groove towards the hole in 10 upper ends in the hole, and the center in three holes equates to the distance of joint 14.With joint 14 is the center of circle, and the angle between tap hole 10 and the osculum 9 is 126.5 degree.Angle between tap hole 10 and water inlet 8 center lines is 126.5 degree.The pedestal upper surface is provided with the spool 12 that is sealed the location by valve gap 11, the circular arc connectivity slot that it is the 175--180 degree that its lower surface offers a radian.

The utility model compared with prior art, has more perfect functions, layout is more reasonable, no water clock, convenient and energy-saving, especially single handle is directly set cold and hot constant temperature setting terminal control mode, be fit to be used for substitute in the prior art two water pipes collocation temperature adjustments or in parallel mix water nozzle and with the supporting use of water heater.

Description of drawings

Accompanying drawing 1 is vertical cross-sectional configuration schematic representation of the present utility model.

Accompanying drawing 2 is the A-A cross section view in the utility model accompanying drawing 1.

Specific embodiment

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing:

Be a cuboid platform shape and place, each chamber is provided with into cold water outlet 1 respectively, goes out in cold water outlet 2, hot water inlet's 3 the valve body inner chamber in the bottom, corresponding each intake-outlet, be separated out water-inlet cavity 4, water chamber 5 and the mixing chamber 6 of mutual isolation, the joint of the partitioning wall of water-inlet cavity 4, water chamber 5 and mixing chamber 6 is 14, and the dewatering outlet 7 that has valve is located on the sidewall of mixing chamber 6.The upper surface of described valve body corresponds to place, each chamber and has water inlet 8 respectively, osculum 9 and tap hole 10, and 9 directions have a dovetail groove 15 towards the hole in 10 upper ends in the hole.The center in three holes equates to the distance of joint 14.With joint 14 is the center of circle, and the angle between tap hole 10 and the osculum 9 is 126.5 degree.Angle between tap hole 10 and water inlet 8 center lines is 126.5 degree.The pedestal upper surface is provided with the spool 12 that is sealed the location by valve gap 11, the circular arc connectivity slot 13 that it is the 175--180 degree that its lower surface offers a radian.

Install and use the utility model new product very simple, will advance cold water outlet 1 earlier and join with tap water, go out the cool mouth of a river 2 and hot water inlet 3 respectively with water heater on intake pipe and outlet pipe be connected and get final product.When manipulating, open valve earlier, spool is turned clockwise, its connectivity slot 13 can cover water intake 8 all the time, and gradually with osculum 9 UNICOMs, tap water is through advancing cold water outlet 1, water-inlet cavity 4, water inlet 8, connectivity slot 13, osculum 9, water chamber 5 and go out cold water outlet 2 enters in the water heater and heats, and then in hot water inlet 3 advances mixing chamber 6, flow out from the dewatering outlet 7 that has valve at last, be hot water this moment, and its water temperature height can be regulated by the area that spool rotation drive connectivity slot covers out cold water hole 9.If this moment is again by the dextrorotation rotary plate, making connectivity slot 13 cover local dovetail groove 15 backs is communicated with tap hole 10, it is communicated with the bypass flow of how much can regulate cold water of dovetail groove 15 sectional areas, final formation mixes the hot water in the mixing chamber 6, finished and comprise and mix temperature adjustment, water temperature from high toward water temperature control low or from low to high.Close hot water if use the valve that dewatering outlet 7 connects instead in the water way, then can current suitable water temperature be locked, then can repeatedly open and close constant-temperature hot water when treating independent thereafter opening/shutting valve.If spool 12 is rotated counterclockwise, when 13 of its connectivity slots cover water inlet 8 and tap hole 10, tap water just can be directly from water-inlet cavity 4, through the water inlet 8, connectivity slot 13, tap hole 10 enter in the mixing chamber 6, because connectivity slot 13 is not connected osculum 9 at this moment, more do not have hot water to enter in the mixing chamber 6,, repeatedly open the then reusable cold water of valve this moment so flow out the dewatering outlet 7 through having valve.
