The automatic flushing valve of described a kind of urinal is characterized in that: described valve rod trigger mechanism comprises just liquid passage, returning spring, ripping bar and the push rod that liquid cylinder, liquid cylinder are connected with just sap cavity; Returning spring is enclosed within on the liquid cylinder, and returning spring is fixed on the base plate of installation cavity; Ripping bar and installation cavity articulate, and an end is fixedlyed connected with liquid cylinder, and the other end cooperates with push rod, and the other end of push rod cooperates with valve rod; One leakage hole is arranged at liquid cylinder bottom, and the leakage fluid dram of leakage hole bottom being positioned at installation cavity is relative, leakage fluid dram and excrement outlet are corresponding.
The automatic flushing valve of described a kind of urinal, it is characterized in that: described plugging mechanism is made of shutoff sheet, cock body and spring, described cock body is positioned at described annular seal space, and reach liquid sealing with described annular seal space, described shutoff sheet is positioned on the pilot hole at described annular seal space top, be connected with guide peg between described shutoff sheet and the described cock body, described guide peg cooperates with described pilot hole, and described spring is on the described guide peg between described cock body and the described annular seal space top.
The automatic flushing valve of a kind of urinal of the present invention also comprises static pressure valve block, compression spring, the valve rod that has spool, valve rod trigger mechanism, and the chamber between static pressure valve block and the spool constitutes the static pressure chamber; Just sap cavity cooperates with the valve rod trigger mechanism; The annular seal space that also has installation cavity, valve stem passage, valve core case, valve block seat and the valve block seat top of valve rod trigger mechanism on the valve body; Valve stem passage is communicated with delivery port, and the static pressure chamber is communicated with water inlet; The water outlet that communicates with delivery port is arranged in the annular seal space, and there is the plugging mechanism of a water outlet annular seal space top; Plugging mechanism is with just the liquid inlet is relative.Owing to adopt such structure, when when urine, just liquid is by the just liquid inlet on the advancing just mouthful of main body, the valve body, the just liquid passage of valve rod trigger mechanism, enter the liquid cylinder of valve rod trigger mechanism, in the liquid cylinder just liquid reach constant weight, valve rod trigger mechanism action, the water of water inlet through the static pressure chamber, valve stem passage is to delivery port, the pressure of static pressure valve block above and below is unequal, this moment, water entered annular seal space, and made the plugging mechanism action, and arrived the delivery port flushing toilet bowl from water outlet; Urine finishes, the effect of the drainage of the leakage hole of liquid cylinder, and liquid cylinder resets, and finishes the flushing action, closes the water source.
Description of drawings
Fig. 1 is a sectional view of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is further described.
As shown in Figure 1 and Figure 2, a kind of automatic flushing valve of urinal, comprise main body 1, valve body, described valve body 2 has water inlet 21, delivery port 22, be positioned at the just liquid inlet 23 at top and just sap cavity 24, have into just mouthfuls 11 on the main body 1, excrement outlet 12, just liquid inlet 23 with advance just mouthfuls 11 relatively, also comprise static pressure valve block 3, compression spring 4, have valve rod 5, the valve rod trigger mechanism 6 of spool, the chamber formation static pressure chamber 7 between static pressure valve block 3 and the spool; Just sap cavity 24 cooperates with valve rod trigger mechanism 6;
Also have installation cavity 25, valve stem passage 26, valve core case 27, the valve block seat of valve rod trigger mechanism, the annular seal space 28 of valve block seat top on the valve body 2; Valve stem passage 26 is communicated with by an exhalant canal 261 with delivery port 22, and static pressure chamber 7 is communicated with by an intake tunnel 9 with water inlet 21; The water outlet 281 that communicates with delivery port 22 is arranged in the annular seal space 28, and there is the plugging mechanism 8 of a water outlet 281 top in the annular seal space 28; It is 23 relative that plugging mechanism 8 and just liquid enter the mouth, and valve stem passage 26 is communicated with delivery port 22.
Described valve rod trigger mechanism 6 comprises just liquid passage 62, returning spring 63, ripping bar 64 and the push rod 65 that liquid cylinder 61, liquid cylinder 61 are connected with just sap cavity 24; Returning spring 63 is enclosed within on the liquid cylinder 61, and returning spring 63 is fixed on the base plate of installation cavity 25 of valve rod trigger mechanism; Ripping bar 64 articulates with the installation cavity 25 of valve rod trigger mechanism, and an end is fixedlyed connected with liquid cylinder 61, and the other end cooperates with push rod 65, and the other end of push rod 65 cooperates with valve rod 5, and push rod 65 is slidingly matched with the dividing plate of the installation cavity 25 of valve stem passage, valve rod trigger mechanism;
One leakage hole 611 is arranged at liquid cylinder 61 bottoms, and leakage hole 611 is relative with the leakage fluid dram that is positioned at installation cavity 25 bottoms, leakage fluid dram and excrement outlet 12 are corresponding.
Described plugging mechanism 8 is made of shutoff sheet 81, cock body 82 and spring 83, between shutoff sheet 81 and the cock body 82 guide peg is arranged, and spring 83 is on the guide peg between cock body 82 and the annular seal space 28, and guide peg cooperates with the pilot hole at annular seal space 28 tops.Cock body 82 reaches liquid sealing with annular seal space 28, and upper and lower the moving of cock body 82 opens or closes water outlet 281.Under normal condition, cock body is closed water outlet 281.
The present invention in use, when promptly inserting urinal, water inlet 21 is connected with the water source, water through intake tunnel 9, enters static pressure chamber 7 by water inlet 21, and gives the static pressure valve block 3 pressurizations simultaneously; The cock body 82 of plugging mechanism 8 is isolated water outlet 281 and static pressure valve block 3, and at this moment, static pressure valve block 3 above and below hydraulic pressure equate that current are in closed condition.
When the people urinates, just just liquid inlet 23 and the just sap cavity 24 of liquid on valve body 1, enter liquid cylinder 61 through just liquid passage 62,, make push rod 65 act on valve rod 5 when the pressure of just liquid weight during greater than the elastic force of returning spring 63, ripping bar 64 rotate, the spool action of valve rod 5, water arrives delivery port 22 by static pressure chamber 7, valve stem passage 26, exhalant canal 261, at this moment, and the above and below pressure disequilibrium of static pressure valve block 3, promptly going up is malleation, is negative pressure down; Water enters annular seal space 28 by static pressure chamber 7, and cock body 82 is moved up, and arrives delivery port, flushing toilet bowl through water outlet 281.
The leakage hole pressure release of liquid cylinder 61, liquid cylinder 61 resets, and finishes a course of action.
