It returns diaphragm 160 to be connected with pressure reducing valve 200, plays the role of sealing, constant current, non-return.Certainly, it can be set in the position of connector
Pressure reducing valve can also be not provided with pressure reducing valve, and if Fig. 7 is the example for being not connected to pressure reducing valve, Fig. 8 is that pressure reducing valve is arranged in connector
Example.
Based on solenoid valve provided by any of the above-described embodiment, the application also provides a kind of valve assembly, as shown in figure 9, packet
Solenoid valve 100 provided by any of the above-described embodiment is included, further includes pressure reducing valve 200.
As shown in Figure 10 and Figure 11, pressure reducing valve 200 include relief valve body 210, decompression connecting rod 220, decompression plug 230,
Depressurize disk 240, decompression diaphragm 250, relief spring seat 260, relief spring 270 and decompression valve deck 280；The decompression connecting rod
220 are arranged in the relief valve body 210；The decompression plug 230 is set in one end of the decompression connecting rod 220；It is described
Disk 240, decompression diaphragm 250, relief spring seat 260, relief spring 270 and decompression valve deck 280 are depressurized successively along far from described
The direction of decompression plug 230 is set on the decompression connecting rod 220, and the decompression valve deck 280 and the relief valve body 210 are solid
Fixed connection.
Preferably, pressure reducing valve 200 further includes decompression adjustment cap 290, and setting is in decompression valve deck 280.It is depressurized by adjusting
The depth of adjustment cap 290 adjusts the pressure of pressure reducing valve water outlet.
Further, decompression connecting rod sealing ring 2100 is provided between the decompression connecting rod 220 and the decompression plug 230
With plug sealing ring 2110；The decompression connecting rod sealing ring 2100 is set on the decompression connecting rod 220, the plug sealing ring
2110 are set on the decompression plug 230.
As shown in Figure 12 to Figure 14, referring concurrently to Figure 10 and Figure 11, liquid enters relief valve body 210 by water flow H, arrives
Up to the position of decompression valve plunger and primary valve, when energized, dynamic iron core, which is adsorbed, leaves the position that primary valve reaches static iron core.
At this moment the hole of primary valve is opened.Liquid enters the decompression area of pressure reducing valve by water flow I.Pass through walking for water flow J and water flow K
To liquid reaches decompression diaphragm 250 and depressurizes the cavity between connecting rod 220, leaves water outlet finally by water flow L.
The space of 250 or more diaphragm is depressurized, that is, the placement region of relief spring seat 260, relief spring 270 is and water
Isolation, the space of this valve body is divided into two parts by decompression diaphragm 250, and it is air that a part, which is water, another part,.
When hydraulic pressure increases, the decompression space below of diaphragm 250 is filled with water, and the space of 205 or more diaphragm of decompression is full of
Air.So decompression diaphragm 250 can be pushed away by the effect of hydraulic pressure to 260 this side of relief spring at this time, drive that has tightened to subtract
Press connecting rod 220 together toward movement at relief spring 270.
When the position that will be contacted between the inclined-plane and relief valve body 210 that decompression connecting rod 220 is moved to decompression connecting rod 220
When, water flow at this time plays certain inhibition for the contact at this, prevents the two contact.Hydraulic pressure is bigger, and water acts on
The power for depressurizing diaphragm 250 is bigger, and decompression diaphragm 250 is pushed, to drive decompression connecting rod 220, to subtract to movement at relief spring 270
Press connecting rod 220 can constantly at this sealing contact surface, and water flow can also accelerate in the case that pressure increases, and water flow is from subtracting at this time
Pass through at faster speed in the gap of pressure connecting rod 220 and 210 contact surface of relief valve body, liquid at this moment is for depressurizing connecting rod
220 and there is bigger thrust at this between sealing contact surface, so that decompression contact surface of the connecting rod 220 far from reducing valve body 210.
And relief spring 270 act on relief spring seat 260 power can and hydraulic pressure act on decompression diaphragm 250 power and
Water flow forms a kind of balance for the inhibition power between decompression connecting rod 220 and 210 contact surface of relief valve body.Need to also it go out
The apopore that a 1.2mm is disposed at the mouth of a river, makes water flow pass through the hole.Power and water outlet of the pressure reducing valve in three in this way
A stable discharge pressure is formed under the interaction of 1.2mm.Regardless of this much pressure all-the-time stable of intake pressure is 0.1
±0.025Mpa.The reducing valve body is only applicable to dynamic hydraulic pressure, in the case that water outlet keeps water outlet, pressure all-the-time stable.
As shown in FIG. 15 to 18, the side of anti-siphon means 130 can also be arranged in pressure reducing valve, thus compression valve assembly
Occupancy width.Anti-siphon means 130 are divided to for two independent parts, respectively correspond water outlet at two.
The overall trend and above consistent of the water flow of above structure, depressurizes the trend of valve portion from the center side of valve body
Enter constant current non-return diaphragm 160 by water flow 1, then enters the cavity of coil and the fixed valve deck of coil by water flow 2.Finally lead to
Electricity, so that primary valve of the dynamic iron core far from coil valve deck 190, reaches the decompression position valve chamber water inlet M under the action of water flow 3.
And the internal structure of the decompression valve chamber is consistent with above-mentioned pressure reducing valve.
Bath valve body N is connected with coil valve deck 190, and coil valve deck 190 is connected with decompression valve chamber.In bath valve body
Constant current non-return diaphragm 160 is used between N and coil valve deck 190, which plays the role of non-return, constant current, sealing.
The foregoing is merely preferred embodiment of the present application, are not intended to limit this application, for the skill of this field
For art personnel, various changes and changes are possible in this application.Within the spirit and principles of this application, made any to repair
Change, equivalent replacement, improvement etc., should be included within the scope of protection of this application.
