Description

The shaft-operated tank for excrement pan

The utility model relates to a kind of shaft-operated tank for excrement pan, is the improvement to existing tank for excrement pan.

In the prior art, the water intaking valve of tank for excrement pan is made up of parts such as plastics spool, valve rod, iron connecting rod, ball float, drift bolts, reaches the water shutoff purpose by envelope water inlet structure on the lever principle.Because it is insecure that the plastics water inlet pipe is connected with end porcelain facing in the water tank, ball float rises with water level, the excessive skew backward of ball float pressure, and water intaking valve can not seal automatically, makes completely constantly outflow of back of water in the case; To be connected the iron drift bolt with the passing of time aging with the water inlet spool for floating ball rod, and ball float can not float and ball float is embedded in the water with water level, and ball float is malfunctioning, and water intaking valve can not be closed voluntarily, and water is outflowed in a large number; Prior art is utilized lever principle, by the lever drives ball float, ball float is pushed down by buoyancy of water in the water tank and the lever reaction force spool of will intaking, reach the water shutoff purpose, intake pressure is during greater than ball float, and the water inlet spool can not be closed voluntarily, water is outflowed in a large number, though have an anti-bleed off pipe that leaks outside water can be discharged in the closet in the case, it is not the water saving loading amount, but the important root of waste water resource; The stifled weight of glue skin is lighter down in the water tank, and when opening water blocking, the hydraulic pressure impulse force is big in the case, makes the stifled unable resilience of the rubber sealing that resets, could form after having only in the case of grade current clean self-closing, especially wash urinate bigger to water consumption; It is stifled that operating crank adopts the mode of tiltedly drawing to open down the glue skin, owing to tiltedly drawing centre-of gravity shift, makes down stifled surface of glue skin and delivery port surface loose contact, formed day and night water clock race and emitted phenomenon.

The purpose of this utility model provides a kind of rational in infrastructure, and the sealed precision height can the automatic control draining, the shaft-operated tank for excrement pan that water-saving result is good.

Technical solution of the present utility model is: comprise casing, case lid, water inlet pipe constitutes a kind of shaft-operated tank for excrement pan, it is characterized in that in casing 1, being provided with water intaking valve 5, draining valve 7 and the axial lifter 8 that starts, wherein, water intaking valve 5 is erect the left rear side that is arranged in the casing 1, the bottom that the inlet valve seat 52 of its lower end is fixed on casing 1 is connected with the tap water joint, the bottom of water inlet valve body 57 and bonding being integral in top of inlet valve seat 52, water inlet spool 54 is arranged on in the water valve body 57, valve core seal ring 53 and spring 62 be arranged on water spool 54 in, the bottom, lifting linking member 58 is connected on the water valve body 57, gravity device 59 is installed in the right terminal of lifting linking member 58, the right side that water inlet starts shifting block 60 and inlet valve seat 52 just external part is connected, the upper end of pull bar 63 is connected with lifting linking member 58, the lower end starts pulling block 6O with water inlet and is connected, and the top of the valve body 57 of intaking is stuck on the claw 2l in the case lid 2; Draining valve 7 is arranged on the center of the bottom in the casing 1, its bottom of holding in both hands in water valve body 74 and the casing 1 is fastenedly connected, holding in both hands the water plug seals up pull bar 71 and is connected with draining sealing backstay 73 and will holds in both hands the water plug and seal 72 and be clipped in center positioning hole 79 places that wherein are co-located on draining valve body 74, the plane of drain plug envelope 72 and the annular cone face of cone face and draining valve body 74 are tightly connected, be respectively equipped with return spring 77 and pin cap 78 on the drain plug envelope backstay 73, the upper end of valve 75 is connected with the bottom of water tank 1, and the other end is connected with draining valve body 74; Axially startup lifter 8 is horizontally installed on the left upper end in the casing 1, its left top that starts axle 82 be arranged on casing 1 handle 4 outward and be connected, startup axle 82 is provided with axle sleeve 85 and is connected with casing 1 upper left side clamping, sealing ring 83 and alignment pin 86 are separately positioned on left end and the middle part that starts axle 82, the front end that starts axle shifting block 87 is arranged in the four directions that starts axle 82 and starts shifting block 60 and be connected with water inlet in the water feed apparatus 5, the bottom of intake and exhaust valve body 88 is connected the rear end that starts axle 82, crossbeam is connected with the case mouth place of casing 1, lower left quarter is connected with air inlet-outlet pipe 3, eccentric wheel 89 is arranged on the end that starts axle 82, and it is sealed up pull bar 71 with drain plug and is connected.

Advantage of the present utility model is, owing to changed envelope water inlet, turnover plate type discharge structure on opened type water tank of the prior art, the lever principle, the self-control of the dual seal water structure down of buoyancy of water and gravity control water inlet water outlet in pressure by tap water, the water tank, thereby reached the better seal effect; Simultaneously, do not establish the bleed off pipe device in the water tank, blocked the channel of wasting water; And adopt axis direction eccentricity wheel to start direct movement in a curve mode, and guaranteed the logical heart degree of draining valve, improved sealing draining precision, having solved in the prior art day and night, water clock runs an essential technique difficult problem of emitting.In a word, the utility model is rational in infrastructure, and water-saving result is good, and the area that takes up room is little, and is easy to install.

Following accompanying drawing has been described structural representation of the present utility model.
