Abstract
The utility model relates to a negative-pressure cold and hot water mixing valve with a single handle. The utility model comprises a porcelain core, a valve core and a valve body covered outside, wherein the porcelain core is composed of a moving plate and a stator; the valve core is composed of a chassis, an upper and a lower washers, a catch plate, a support bracket, a deflector rod, a deflector rod shaft and a valve core case. The utility model is characterized in that the stator is provided with four bores in symmetry of the center of circle. The joint plane of the moving plate and the stator is provided with two mould cavities similar to a right angle type with tops outward in symmetry of the center of circle. The diameter of the moving plate is smaller than the diameter of the stator, and the moving plate can move parallelly along the central line of the moving plate and rotate for 90 DEG around the center of circle of the stator on the plane of the stator. A cold water pipeline and a hot water pipeline which are arranged in the valve body are separately communicated with the two water outlet holes of the stator. The cold water pipeline intersects with the hot water pipeline at the angle of alpha <=90 DEG and is communicated with the hot water pipeline after folding to the right vertically, and negative pressure is formed to suck hot water to flow out in fast mixing. The utility model solves the disadvantages that the mixing valve with a single handle has low pressure for hot water and high pressure for cold water to lead to difficult temperature adjustment and small flow capacity; the water outlet is sometimes cold and sometimes hot because of cold water pressure discontinuity.
Description
Technical field
The utility model has related to a kind of bigger negative pressure type hot and cold water single handle mixing valve of hot and cold water pressure reduction that is applicable to solar water heater and electric water heater.
Technical background
In prior art, the water mixing valve of single handle control, mostly the stator structure in its porcelain core is three water ports, and wherein two long and narrow arc shaped holes are respectively the hot and cold water water port, and the 3rd is the mixing water water port; A blind hole (die cavity) that can be communicated with three holes (at least two holes) on the stator is then arranged on the moving plate, be characterized in: hot and cold water enters this porcelain core respectively in proportion and mixes the back and flows out (two-way inflow, one the tunnel flows out, conventional usage), also can oppositely use, promptly water enters from the mixing water water port, and its flow flows out (one tunnel inflow in proportion respectively from the hot and cold water water port then, two-way flows out, and is used for the shower of certain open type electric water heater).Its shortcoming is: when using as the shower mixing valve when two water intake end pressure differences are big, as solar water heater or open type electric water heater, the cold water hydraulic pressure height because pressure of hot water is low, the result causes temperature adjustment inconvenience, and flow is little, will cause the mixing water temperature fluctuated and can't use for another example when cold water end variation in water pressure.
Summary of the invention
The objective of the invention is to overcome above shortcoming, a kind of ceramic valve core that has improved is provided, a kind of mixing valve that uses this spool is provided simultaneously, and in this valve, introduce fluidics, before mixing, hot and cold water make cold water in the outflow process, hot water pipeline be produced negative pressure, quicken the outflow of hot water and mixing with it, thereby solved between the hot and cold water because of the excessive and difficult adjusting temperature of pressure reduction, water flow is little and cause disadvantage such as mixing water temperature variation because of cold water end pressure sudden change, simultaneously, because be single handle operation, so it is simple to operate, convenient, fast,, using water wisely has reduced cost.But, its mode of operation and prior art are different, and promptly lifting handle up and down is temperature adjustment, and rotatable handle is switch and regulates flow.
The utility model is on the basis of existing single handle mixing valve the porcelain core in the existing spool have been carried out new design, and in conjunction with the valve body that has improved, is achieved above-mentioned functions.Being about to stator, to be provided with four be the hole of symmetry with the center of circle, moving plate is provided with two on the plane that fits with stator be the outside class right angle type die cavity in summit of symmetry with the center of circle, moving plate is littler than stator diameter, moving plate can be done the parallel rotation of moving and doing 90 degree around the center of circle of stator along the center line of moving plate on the stator plane, this structure can flow out porcelain core respectively in required ratio with the flow that enters the hot and cold water of porcelain core by valve body respectively, and in valve body, be provided with two pipelines and be communicated with two osculums of stator respectively, one is cold water outlet conduit A
1, another is hot water effluent's pipeline B
1, cold water pipes A wherein
1After the vertical right folding with hot water pipeline B
1Intersect to be communicated with, its crossing angle [alpha]≤90 °, thereby, in cold water outflow process, hot water pipeline has been formed negative pressure, attract hot water to flow out fast, and mix with it and flow out valve.It has solved preferably that single handle mixing valve is low for the heat hydraulic pressure, cold water pressure is high and temperature adjustment difficulty, flow that cause are little and make the sometimes hot and sometimes cold shortcoming in waterexit end because of the cold water pressure sudden change.
