Abstract

The utility model relates to a floating bucket type water charging valve for a water tank of a bowl, which has the structure that a rubber valve element 15 and a valve seat 17 form a hollow cavity, a hole in an upright post on the valve element is matched with a diameter changing shaft 16, and the diameter changing shaft is connected with a floating bucket through a lever and a connecting rod; a water charging piper is fixedly installed on the water tank and is divided into an inner pipe and an outer pipe, wherein from the inner pipe, water enters a gap between an inner wall and an outer wall outside the pipe and flows out from the bottom of the water tank; a water out part at the upper end of the water charging pipe is aligned to the valve element, and the valve element controls water discharging. The utility model is characterized in that a baffle plate c is arranged in a floating bucket 8, and the water inlet of the floating bucket is in a flat port type; the diameter changing shaft is in a four-segment stepped cylindrical structure. The utility model has the advantages of high operating sensitivity, water saving, compact structure and low noise.

Description

The float bowl-type inlet valve of water tank

The utility model belongs to the tank for excrement pan inlet valve.

Usually the tank intake valve of water majority adopts float-ball types.Shortcoming is to need the long lever that links to each other with ball float, just can overcome the suffered water flow pressure of valve member.Therefore, physical dimension is big, operates dumbly, and can not regulate water level, and the current noise is big.The float bowl-type inlet valve of later invention, though physical dimension reduces, can regulating water-quantity, the current noise reduces, but its keg float structural type as shown in Figure 3, and the inner chamber bottom of keg float 8 all is filled with water, and makes keg float bigger in the total force moment ratio that is subjected to when conduit (adjutage) descends, and collapsable shaft 16 as shown in Figure 5, and its pattern adopts five joint cascade cylindrical structurals.Blocked by conduit easily when the such scheme shortcoming is keg float decline, keg float and water level can not descend synchronously, and the structural type of collapsable shaft also influences the sensitivity of inlet valve work.

The purpose of this utility model is to design a kind of tank for excrement pan inlet valve, and is should physical dimension little, noise is little, and regulating water-quantity is convenient, can operate nimblely again, and keg float can descend synchronously with water level.

With reference to the description of drawings technical scheme:

As shown in Figure 1, inlet valve mainly is made of two-part up and down.Top is installed into the control mechanism of water valve, comprises the cavity that rubber valve member 15 and valve seat 17 form, and the rubber valve member protrudes out the column of hollow to cavity, and its center hole and collapsable shaft 16 match, and the aperture that the cross center hole is arranged on the column is with the connection cavity.The collapsable shaft upper end links to each other with lever 2, and the lever the other end links to each other with connecting rod 5 and keg float 7,8.Pipe 4 in the water is arranged at the bottom, and outer tube 9 is established inside and outside two layers of walls, inwall and 4 sealings of interior pipe, from interior water inlet tube through valve port to outer tube, from the downward water outlet in the gap between the inside and outside wall, the reduction noise.Adjutage 3 is sleeved on outer tube outside, turn adjutage regulating level.Intake pipe is fixed with water tank by nut 23 and packing ring 21.When two-part made up up and down, the water outlet of pipe 4 upper ends should be aimed at the porose position of valve member 15 in the water inlet, by valve member control water outlet.The main feature of this programme is the improvement of keg float 8 structures.As shown in Figure 2, establish dividing plate c in keg float, and the keg float water intake is improved to flat shape of the mouth as one speaks formula by prior art protruding d shown in Figure 3, the inner chamber that makes keg float 8 an only side is filled with water, and is evenly distributed on around the conduit; As shown in Figure 4, collapsable shaft 16 is four joint cascade cylindrical structurals; Only a kind of bore of prior art intake pipe, this programme is set up a joint that two kinds of bores are arranged, it is of a size of G1/2 "; Stiffening rib is established at top at the valve seat 17 that valve member 15 is installed.

Advantage of the present utility model:

Because keg float 8 an inner chambers only side are filled with water, the gross weight moment that is subjected to when keg float is descended significantly reduces, can effectively improve sensitivity, compare with prior art as shown in Figure 3, Operational Figure Of Merit can improve four times under water inlet weight the same terms, realize that keg float and water level descend synchronously, and guarantee when keg float descends, can not blocked by conduit; The also favourable raising sensitivity of the improvement of collapsable shaft 16 structures; Joint owing to be equipped with two kinds of bores in water inlet place is user-friendly to.
