Detailed description of the invention
In order to make those skilled in the art be more fully understood that the technical solution of the utility model, under
Face combines the drawings and specific embodiments, and the utility model is described in further detail.
Refer to Fig. 1 to Fig. 3, Fig. 1 is for water purification system in this utility model one embodiment
The three dimensional structure schematic diagram of the cross valve of system；Fig. 2 is the sectional view of cross valve shown in Fig. 1；Figure
The exploded perspective view that 3 is cross valve shown in this Fig. 1.
This utility model provides a kind of cross valve for water cleaning systems, and cross valve includes following
Parts valve body 1 and spool 3.Specifically, valve body 1 offers axially aligned outside it
One working hole the 11, second working hole the 12, the 3rd working hole the 13, the 4th working hole 14, valve body
1 has valve pocket, the closed at both ends of valve pocket；Usually, the upper end of valve pocket is hatch frame,
Spool 3 loads inside valve pocket from this opening, the most generally by the upper end of valve gap 2 closeding valve cavity
Opening, valve gap 2 forms the roof of valve pocket.
It is pointed out that first, second, third, fourth word such as grade herein is only for district
The same or similar plural parts of separation structure, function, do not indicate that certain spy to order
Different restriction.The most upper and lower wait the noun of locality be with parts each in Fig. 2 between relative position close
System is defined, merely to description technique scheme is succinct, those skilled in that art should
Working as understanding, the use of the noun of locality herein should not limit protection domain herein.
Spool 3 is arranged at the valve pocket of valve body 1, and can valve body 1 slides relatively spool 3；
Valve pocket is divided into upper chamber and lower chambers by spool 3, and the upper end of spool 3 is close with upper chamber circumference
Envelope, bottom and lower chambers circumferential seal；The valve pocket of valve body 1 can include big footpath section herein
With path section, the first working hole 11 is located at described big footpath section, and remaining working hole is located at path section；
Correspondingly, described big footpath section is located in the upper end of described spool 3, and remaining section is located at described path
Section.That is being relatively large in diameter of the upper end of spool 3, the diameter of interlude and bottom is little
Upper end in spool 3.Therefore the upper end of spool 3 connects interlude by First terrace,
The big footpath section of valve pocket by second step face connect valve pocket path section, when First terrace against
During second step face, spool 3 stops moving down.
The first working hole 11 in this utility model connects upper chamber, and the 4th working hole 14 connects
Lower chambers, the interlude periphery wall of spool 3 is additionally provided with groove 31, and the inside of spool 3 also has
There is the passage of connection lower chambers and periphery wall；This groove 31 can be annular groove, it is also possible to for
Other shapes, as long as being capable of the connection of above-mentioned two each working holes.
Introduce technique effect as a example by connecting by cross valve and water cleaning systems working, work as water cleaning systems
When carrying out controlling the water circulation work, kitchen water flows into the 4th working hole 14 of cross valve, and pure water is through pressure pot
Rear portion transmission flows into the 3rd working hole 13, another part through active carbon filter core, non-return valve
First working hole 11.Now cross valve is in the second duty, and spool 3 is positioned in valve pocket
Portion, the 4th working hole 14 connects with the 3rd working hole 13, the 3rd working hole 13 and the second work
Mouth 12 connection, the kitchen water of system flows out from the second working hole 12, flow to discharge outlet.
When prepared water is on the increase, and spool 3 moves down, until being displaced downwardly to bottom valve body 1 reach
The full state of water, is now in the first duty of cross valve, the i.e. second working hole 12 and the 3rd
Working hole 13 is connected by groove 31, non-interconnected between other working holes；
When using water, opening faucet, the hydraulic pressure of cross valve the first working hole 11 will reduce, valve
Core 3 slowly rises, the 3rd working hole 13 with by channel connection the 4th working hole 14, kitchen
Water flows into the 3rd working hole 13 from the 4th working hole 14, non-interconnected between other working holes, from
And making pressure pot outer chamber hydraulic pressure increase, the pure water in extrusion valve pocket, the most now cross valve is in
3rd duty.
As it has been described above, the cross-sectional area of the upper surface of spool 3 is excellent more than the cross-sectional area of lower surface
Choosing, the cross-sectional area of the upper surface of spool 3 is 2 with the ratio of the cross-sectional area of lower surface,
So spool 3 can be automatically stopped in the middle part of valve pocket, is in controlling the water circulation position.
Cross valve spool 3 action vertically in this utility model, can be by effect and spool
Pressure medium on 3 upper surfaces, lower surface carries out action, appropriate design upper surface, lower surface
Area can realize the reliable slip of spool 3, the cross valve of this structure is to spool 3 two ends water
Pressure sensitivity should be sensitiveer, as long as two ends hydraulic pressure slightly changes, spool 3 the most slidably, therefore to water
It is pressed with requirement ratio relatively low, even if hydraulic pressure is too low, also can well control the break-make of internal watercourses.
In the various embodiments described above, the opening size of annular groove the most gradually becomes
Greatly, the annular groove of this structure is conducive to spool 3 the most slowly to slide.
In the various embodiments described above, connection lower chambers includes first vertically with the passage of periphery wall
Passage 37, second channel 32 radially, first passage 37 outer end connects the lower end of spool 3
Face, the inner of inner connection second channel 32.
Further, the inside of spool 3 also has solution cavity, the inner of first passage 37,
The inner of second channel 32 all connects solution cavity.
Specifically, the bottom of valve body 1 is provided with installing hole, and valve rod 4 is located at described installing hole
Inside, and valve rod 4 can be with passage (first passage 37) fitted seal, specifically, valve rod
The end of 4 can arrange sealing-plug 41, and sealing-plug 41 seals with the outer end of first passage 37.
Valve pocket includes that big footpath section and path section, the first working hole 11 are located at big footpath section as mentioned above,
Remaining working hole is located at path section；Correspondingly, big footpath section is located in the upper end of spool 3, remaining
Section is located at path section.
It addition, the upper end of spool 3, bottom can all offer ring-type mounting groove, each ring
Being disposed with sealing ring in shape mounting groove, described spool 3 is by corresponding sealing ring and described valve pocket week
To sealing.As in figure 2 it is shown, be provided with sealing ring 21, sealing ring 33, close on each section of spool 3
Seal 34, sealing ring 35, sealing ring 36
Above a kind of cross valve for water cleaning systems provided by the utility model is carried out
It is discussed in detail.Principle of the present utility model and embodiment are entered by specific case used herein
Gone elaboration, the explanation of above example be only intended to help to understand method of the present utility model and
Its core concept.It should be pointed out that, for those skilled in the art, not
Depart from the premise of this utility model principle, it is also possible to this utility model is carried out some improvement and
Modifying, these improve and modification also falls in this utility model scope of the claims.
