The bypass part 30 of the present embodiment and the operation principle of piston 20：
As shown in fig. 6, pitch brace 40 has an external force F to piston 20, there must be one from bypass part 30 and phase
Reverse friction power f between the first seal member 51 answered, to maintain the position of bypass part 30, bypass part 30 and piston
20 are opened and closed internal channel 60 together, when the opening and closing degree very little of internal channel 60, according to the Bernoulli equation after simplification：
Wherein P is pressure, and V is water flow velocity, and ρ is water density, and g is acceleration of gravity, and C is constant value；When internal channel 60
During opening and closing degree very little, V2 here is far longer than the flow velocity V1 at water, necessarily leads to one than larger pressure differential deltap P=P1-
P2.Generally before the opening of internal channel 60, bypass part 30 right atrial pressure P3 is equal to intake pressure P1, so bypass part 30 also can
In the presence of a same pressure difference, and then a thrust Fa is formed, if be less than without reverse friction power f or reverse friction power f
Thrust Fa, can cause internal channel 60 not open.But while thrust Fa promotes bypass part 30, damping hole as shown in the figure
There is also a high-velocity flow inside 35, can also form a reverse differential pressure can offset thrust Fa, so as to maintain bypass
The free state of part 30, until the contact of lug boss 41 comes to push directly on.According to test result, it is preferred that the damping hole
The sectional area ratio of 35 sectional area and the top surface 31 of the bypass part is 1：4000~1：400 be optimal.That is, working as
The sectional area ratio of the sectional area of the damping hole 35 and the top surface 31 of the bypass part is more than 1：400, damping hole 35 is interior to be produced
Reverse differential pressure be not enough to offset thrust Fa so that bypassing part 30 can persistently be pull-in on the one end of piston 20；And when the resistance
The sectional area ratio of the sectional area in Buddhist nun hole 35 and the top surface 31 of the bypass part is less than 1：4000, avoid side although can also realize
Logical part 30 can be pull-in on the one end of piston 20, but is due to that the reverse differential pressure produced in damping hole 35 is excessive, can cause driving
The electric current of the motor of pitch brace 40 is excessive, so as to shorten the life-span of motor.
Under inactive state after internal channel 60 is opened completely, V2 flow velocitys can decrease, pressure differential deltap P and thrust Fa
Will significantly it reduce, adding the adverse current suction water-carrying capacity of salt passage 72 itself can all ensure to bypass part with regard to very little, and reverse friction power f
The holding of 30 state.But if internal channel 60 can not be opened fully before, the effect of lug boss 41 can fail always, inverse
Stream, which inhales salt passage 72, can also close, so as to influence the adverse current of multi-way control valve to inhale the realization of salt functional.
As shown in fig. 7, in figure piston 20 be located at the stroke of piston 20 distalmost end when position, i.e. backwash position when piston 20
In the signal of inactive state, the now corresponding backwash passage 73 of internal channel 60, because general backwash water is all very big, flow velocity V2 also can
Rise, lasting thrust Fa progressively adhesive can bypass part 30, and the position-limit foot 34 for bypassing part 30 can be limited in grid 11
Limited step 118 position, so that it is guaranteed that the stability of backwash state.
As shown in figure 8, piston 20 is located at the state after the closure of internal channel 60 when the return of piston 20 is moved to right, similarly, resistance in figure
Buddhist nun hole 35 is supported in the cushioning effect of closure moment, the reverse differential pressure for also coming from producing in damping hole 35 to thrust Fa moment
Disappear, then external force F pulls piston 20 and bypass part 30 together, in each ensuing regenerative process, comes at water pressure P
In the endoporus 22 of piston, exhalant canal 71 is closed, and is opened until the top of piston 20 and is bypassed part 30, so that internal channel 60 is opened, and
Make the correspondence exhalant canal 71 of internal channel 60, into the operation water process of control valve, regenerative process terminates.
The valve core modular construction for multi-way control valve of the present invention is simple and compact to design, greatly reduces multichannel control
The overall volume of valve processed；The present invention is full-featured, realizes the adverse current closed under hard water bypass and all techniques of co-current regeneration
Process, reduces internal piston and hits, realize reduction fault rate；The present invention greatly reduces the system of integrated multipath control valve simultaneously
This is caused, while extending the bulk life time of multi-way control valve.
