Concrete enforcement:
" anti-overflow excrement device " shown in Figure 2 is by float 1, push rod 2, valve block 3, valve seat 4, surge chamber 5 formations such as grade.Surge chamber 5 valve blocks 3 usefulness welding sets become one with cover 6 on cover 6, they two cylindrical center on an axis, the valve port of valve seat 4 upper ends opens wide up.
Fig. 2 partial view A, B can see the situation of push rod 2 in surge chamber 5 upper and lower plate holes, the diameter of surge chamber 5 upper and lower plate holes is greater than the diameter of push rod 2, between push rod and surge chamber 5 upper and lower plate holes, certain space is arranged respectively, these two spaces are valve blocks 3 when opening, and air enters the part of jar internal channel outside jar.
Valve block shown in Fig. 3 partial view is that two parts are formed, and is iron plate above, is rubber tile below.The rubber tile pad played good sealing function when breather valve was closed between valve seat and iron valve block 3.
The fecal suction truck " anti-overflow excrement device " of this case invention is as Fig. 2, and it is by the float in jar 1 floating height of responding to excrement slurries face 11 in the jar in liquid level 11 not.Connect push rod 2 on the float, what push rod 2 was erect is enclosed among valve seat 4, the surge chamber 5, and push rod 2 upper units have valve block 3, and the weight tenesmus by float 1, push rod 2 and valve block 3 at ordinary times is sitting on the valve port of valve seat 4 valve block 3.By the weight of float 1 push rod 2 and vacuum the suction of valve block 3 is come the hermetically closing valve block when inhaling excrement.Its opening process is such, when the liquid level in the feces tank 7 is about to reach setting height, be located at the float 1 floating generation buoyancy in jar on the anti-overflow excrement device, at this moment liquid level continues to increase, the buoyancy of float 1 is also given greatly thereupon, having arrived the buoyancy of float 1 gives big to overcoming float 1, the weight of push rod 2 and vacuum are during to the suction of valve plate, float, the push rod band valve block and is moved on together and open valve block 3, at this moment, air outside jar enters in the jar from valve port rapidly, make a jar interior vacuum expendable pattern, stop to inhale excrement, it is enough big to advance jar interior air capacity from valve port, certain vacuum that vacuum pump continuation this moment has been inhaled the good one-tenth of vacuum not, do not inhale the excrement slurry, realize the purpose of anti-overflow jar.Manually adjust the position height of float 1 on push rod, just can set the effect moment of anti-overflow tank arrangement.
Fecal suction truck is in the process of inhaling excrement, viscosity difference because of the powder slurry, inhale the not equal reason of vacuum value of velocity, cause the variation of being carved with when jar interior vacuum is different this moment by a small margin, vacuum also has a little variation to the suction of valve block 4 constantly in difference, this variation is very little as long as float enough has enough buoyancy greatly, and the application point of anti-overflow tank arrangement is adjusted at the maximum suction moment of vacuum to valve block, just can not influence the operate as normal of anti-overflow tank arrangement.
Fecal suction truck sucks excrement, excrement slurry is moved to the appointed place opens and puts the excrement valve and bleed off the excrement slurry, and float 1 does not have the effect tenesmus of buoyancy nature at gravity, is sitting on the valve seat 4, and automatic-closing valve is next suction excrement ready for operation of determining.
The visiting fecal suction truck that ends of surge chamber 5 usefulness shown in Figure 2 is when walking, and the excrement slurry has shaken and flung valve plate along push rod.
Liquid level 11 was bit by bit to raise when fecal suction truck was inhaled excrement, liquid level 11 produces and rocks under the impact of advancing excrement, say that by convention float 1 swims in liquid level and bit by bit raises, and under the situation that liquid level 11 rocks, float 1 and push rod 2 can be with to move on valve plate 3 piecemeal the rocking and open valve, like this valve plate 3 when just opening, have one like Kai Feikai like the process of Guan Feiguan, this process can make slow, blunt, unable that the valve open action of " anti-overflow excrement device " becomes.Can takeoff rapidly during " anti-overflow excrement device " valve open of this case design and carry out rapidly.Its operating principle is such, and it has utilized the buoyancy of float 1 cleverly, and the gravity of float 1 and push rod 2 and vacuum are to the interaction between the suction of valve plate 3.Opening of valve plate 3 is that buoyancy by float 1 overcomes the weight of float 1, push rod 2 and moves on floating and open, the effect of " anti-overflow excrement device " is constantly when inhaling excrement, have certain vacuum in the jar this moment, vacuum produces suction to the valve plate of closing 3, and the valve plate 3 of this case " anti-overflow excrement device " takeoffs rapidly when opening and leans on vacuum that the suction of valve plate 3 is suddenly disappeared to realize.Its operating principle is such, liquid level 11 in feces tank 7 is elevated to levitating float 1 and begins to produce buoyancy, liquid level 11 continues to raise, float 1 drinking water is also along with deepening, buoyancy is also increasing, when being increased to the weight of the big sub-float 1 of float 1 buoyancy, push rod 2 and vacuum to the suction of valve plate 3, float 1, push rod 2 are being with to move on the valve plate 3 and are being opened valve, enter in the valve seat 4 at the moment air of opening valve, valve plate has had for 3 times air to lose the suction of vacuum to valve plate 3, and vacuum suddenly disappears to the suction of valve plate 3 and broken the balance of buoyancy.The buoyancy of float is much larger than the gravity of float, push rod at this moment, so float, push rod can float one section rapidly with valve plate and reach new buoyant equilibrium (buoyancy=float gravity+push rod gravity+valve plate gravity), this section of floating rapidly can make valve plate 3 jump out of valve seat 4 one segment distances immediately, and valve is effectively opened rapidly.
Comprehensively above-mentioned, to inhale excrement when fecal suction truck and enter in the feces tank, the demarcation that promptly will expire the accurately action of sensitivity of anti-overflow tank arrangement constantly prevents the generation of excessive jar phenomenon, pollution and the damage that vacuum system is not starched by excrement inhaled in protection.
