Specific embodiment
A kind of mechanical switch valve is connected with bonnet, 1 and lower valve on the coaxial corresponding upper port and lower port of valve body 7 respectively
Lid 8 is equipped with the water inlet A 101 and water outlet A 102 being mutually communicated in bonnet, 1, is equipped with water inlet B 701 and water outlet in valve body 7
Mouth B702, the channel between water inlet B 701 and water outlet B 702 are equipped with valve seat A9, the upper port of valve seat A9 and valve body 7
It is coaxially corresponded to lower port, the valve seat B10 and water outlet C801 being mutually communicated is equipped in bottom flange 8, valve seat B10 and valve seat A9 are same
Axis correspondence and an alternate distance, the upper port of valve body 7 and 1 junction of bonnet, envelope are connected with diaphragm 4, and diaphragm 4 is connected with below
Piston 5,5 lower end of piston are passed down through the valve seat A9, and piston lower end radial dimension is less than valve seat A9 port radial dimension,
Cause the corresponding valve seat A passage port of piston lower end that there is annular fluid course, piston is connected with piston cap 6, the piston cap position
In in the region of a valve seat B10 distance alternate with valve seat A9, the upper and lower sealing surface of the piston cap 6 respectively with valve seat A9 and
Valve seat B10 is corresponding.The channel of the water inlet A and water outlet A is equipped with the current limliting including traffic controller 2 and flow circle 3
Device increases the pressure between water inlet A and water outlet A in channel when for water delivery, guarantee to have enough pressure by diaphragm 4 together with
Piston 5 is depressed.
Illustrate that this switching valve is used in the functioning condition of dish-washing machine below.Dish-washing machine is equipped with water demineralizer, water demineralizer
Resin bed be filled with ion exchange resin, resin makes to need after the full period with brine regeneration, and sodium ion when regeneration in salt water is set
The calcium and magnesium ion in resin is changed, output is rich in the waste water of calcium and magnesium ion；Soft water output and waste water output are same outlet, should be gone out
Mouth and the water inlet B 701 of this switching valve are led to.
Washing state: tap water successively passes through the resin bed in external channel one and demineralizer, exports soft water from the outlet；
Not water flowing (water inlet A 101 is connect with external channel two) between water inlet A 101 and water outlet A 102 at this time, diaphragm 4 are in lift
The state of rising, correspondingly piston 5 lifts, and sees Fig. 3, and piston cap 6 is lifted off a seat B10, seals valve seat A9；The soft water of output is from water inlet
Mouth B701 input, exports from water outlet C801.
Reproduced state: tap water passes through external channel two, then passes sequentially through water inlet A 101 and water outlet A 102, inputs
Salt chamber enters resin bed and regenerates to resin from salt chamber output salt water, regenerates the waste water rich in calcium and magnesium ion of generation from institute
State outlet output；In the process when tap water passes through water inlet A 101 and water outlet A 102, hydraulic pressure presses diaphragm 4 together with piston 5
Under, see Fig. 4, piston cap 5 is lifted off a seat A9, and valve seat B10 is sealed；The waste water of output is inputted from water inlet B 701, from water outlet
B702 output.
After regeneration ending, washing state is returned, diaphragm 4 lifts at this time, and the soft water of output is inputted from water inlet B 701, from
Water outlet C801 output.
The switching valve of the utility model can automatically switch flow path, and structure without the running that is powered without electrical, electromagnetic component
It makes simply, can be small in size to which duty is small, manufacturing cost is low；Besides this switching valve can all be exempted to use metalwork, at least
With liquid contact position, especially there is the liquid contact position of corrosiveness that can not have to metalwork with salt water etc., to avoid component
Corrosion, optimize using effect, prolong the service life.
