Embodiment 1
As depicted in figs. 1 and 2, the utility model provides a kind of multi-way valve, is connected to water softening device by tank body connector
Tank body comprising water inlet 14, drainage cavity 144, bypass cavity 145, intake antrum 146, suitable for reading 147, lower mouth 148, water outlet 15, row
The mouth of a river 21, drain valve 22, triple valve 5, check valve 6 and injector 41, salt-sucking port 81, in addition, tank body connector includes the first tank
Mouthfuls 141 and second tank mouth 142 to be correspondingly connected to the in-out end of soft water machine jar body.
Triple valve 5 specifically includes sealing, driving portion and spring 52, and sealing can move back and forth, with suitable for reading in sealing
It is switched between 147 and the sealing state of the lower mouth 148 of sealing, and driving portion is then connected to sealing, driving portion setting exists
Between drainage cavity 144 and intake antrum 146, driving portion is close to control by the pressure change between drainage cavity 144 and intake antrum 146
The sealing state in envelope portion, spring 52 is then for providing the screen resilience resetted to driving portion.In the present embodiment, which is one
Piston, it is past between drainage cavity 144 and intake antrum 146 to be changed by the pressure difference between drainage cavity 144 and intake antrum 146
Multiple movement.
Water inlet 14 is connected to by suitable for reading 147 with intake antrum 146 and the first tank mouth 141, in addition, water inlet 14 is under
Mouth 148 is connected to bypass cavity 145, and then is respectively communicated to the second tank mouth 142 by check valve 6 and injector 41.
Wherein, the both ends of injector 41 are respectively communicated in bypass cavity 145 and second tank mouth 142, the injector 41
Negative pressure end is then used to connect salt box (not shown), i.e., the negative pressure end is the salt-sucking port 81 in multi-way valve, and the two of check valve 6
End is then respectively communicated in bypass cavity 145 and the second tank mouth 142, when in multi-way valve flowing water along bypass cavity 145 to described the
When the direction flowing of two tank mouths 142, check valve 6 is in off state.
By triple valve 5 to suitable for reading 147 and the switching of the sealing state of lower mouth 148, it is being connected to water inlet 14 into water
Chamber 146 and being connected between the two states of bypass cavity 145 switches over, so that water inlet 14 can be respectively to the first tank mouth
141 and second tank mouth 142 supply water, i.e. flow direction of the change water in multi-way valve.
As shown in Figure 1, it is multi-way valve in operation water state schematic diagram, since drain valve 22 is closed, drainage cavity 144 is pressed
Power is equal to 146 pressure of intake antrum, and spring 52 pushes triple valve 5 to physical slot, that is, seals lower mouth 148, arrow as shown in figure 1 of intaking
Shown in by 14 to the first tank mouth 141 of water inlet, soften hence into the softening resin bed of soft water machine jar body (not shown)
Water processed, then multi-way valve is returned from the second tank mouth 142, check valve 6 is opened later again by the outlet valve 16 of opening to water outlet 15.
Period, since the no pressure difference of the inlet and outlet of injector 41 cannot form negative pressure, from the softened water meeting of the second tank mouth 142 outflow
It is filled the water from salt-sucking port 81 into salt box.Wherein, the water of water filling needs to carry out by fluid level control valve control built-in in salt box
Control makes it that stopping water filling being automatically closed after filling.
Shown in Fig. 2, for multi-way valve suction salt+rinse status diagram slowly, at this time open drain valve 22, make drainage cavity
144 after by 22 pressure release of drain valve, and pressure is less than the pressure of intake antrum 146, therefore triple valve 5 can overcome spring force, position
Suitable for reading 147 are sealed after shifting and open lower mouth 148.Water inlet can enter bypass cavity 145 from water inlet 14 as shown by the arrows in Figure 2, by
Off state is under the flow direction in check valve 6, therefore water can flow to the second tank mouth 142 by injector 41, make to spray
The negative pressure end (i.e. salt-sucking port 81) of device 41 forms negative pressure, salt water in salt box is sucked multi-way valve by salt-sucking port 81, and mixed with water
After conjunction by the second tank mouth 142 enter soft water machine jar body resin bed carry out counter-current regeneration, waste liquid by the first tank mouth 141,
Drainage cavity 144, drain valve 22 are discharged by discharge outlet 21 again.Wherein, after saline solution sucks in salt box, fluid level control valve is closed, and is opened
Begin to rinse slowly.
After above-mentioned slow flushing process terminates, as shown in figure 3, can further open multi-way valve gets valve express developed
31, after this, which gets valve 31 express developed, is turned on, the water inlet positioned at bypass cavity 145 can get around injector 41 and directly to the second tank
Mouth 142 provides the water flow of big flows, to get resin bed express developed, even if obtaining multi-way valve enters fast flushing state.Resin bed again
It after life, drain valve 22 and gets valve 31 express developed and simultaneously closes off, outlet valve 16 is opened, and the operation water state in Fig. 1 is returned to.
The multi-way valve by being connected to injector 41 between bypass cavity 145 and the second tank mouth 142 side by side with check valve 6,
Make multi-way valve when in water state processed is run, water flows to bypass cavity 145 from the second tank mouth 142 by check valve 6, and is locating
When inhaling salt state, due to the closing of check valve 6, water from bypass cavity 145 flow to the second tank mouth 142 by injector 41, with
The negative pressure end (i.e. at salt-sucking port 81) of injector 41 forms negative pressure, so that salt water passes through the sucking of salt-sucking port 81 multi-way valve simultaneously in salt box
Into soft water machine jar body, multi-way valve is made to can be realized the function of inhaling salt, meets the needs of being applied on water softening device.
The multi-way valve low cost miniaturization triple valve on the basis of, by bypass circulation increase check valve 6 and
It is connected to the injector 41 of salt box, makes the multi-way valve that can also realize suction salt functional, to meet the needs of applying on water softening device.It should
Multi-way valve compared to the prior art in water softening device control valve, due to eliminating the transmission mechanism and motor of traditional automatic soft valve
This two big important module, therefore also have the characteristics that low-profile, easy to install and use, cost is lower.
In the present embodiment, the end of the water outlet 15 of multi-way valve has outlet valve 16 with the open and-shut mode to water outlet 15
It is controlled, is in close state water outlet 15 (referring to figs. 2 and 3) in entire regenerative process, as non-hard water bypass.
Certainly, in other embodiments, which can also remove outlet valve 16, even if obtaining water outlet 15 in entire regenerative process
It is constantly in the state that can flow out hard water, as hard water bypasses, and multi-way valve is made to meet the demands such as civilian.
In addition, the multi-way valve further includes a constriction, which is arranged between drainage cavity 144 and intake antrum 146, when
When drain valve 22 is opened and carries out pressure release to drainage cavity 144, due to the effect of constriction, it can limit to flow into from intake antrum 146 and arrange
The flow of the water of water cavity 144, and then the pressure difference between drainage cavity 144 and intake antrum 146 is increased, guarantee the driving of triple valve 5
Portion can switch the sealing state of sealing with pressure change, improve the reliability of the multi-way valve.
The utility model also provides a kind of water softening device, uses multi-way valve as described above.Since the multi-way valve eliminates
Transmission mechanism and motor this two big important module in traditional soft water valve, therefore there is low-profile, easy to install and use, cost
Lower feature can effectively reduce the overall cost of the water softening device.
