Abstract

The utility model relates to a straight-dropping type double-shift drainage valve for a water tank of a toilet closet. A guide cylinder is arranged on a shell, and a valve composed of a stepped shaft and a sealing rubber pad is arranged in the shell. The utility model is characterized in that an adjusting tube (4) above the guide cylinder (2) forms a sliding fit with a cylindrical section D3 of the steeped shaft, a water box (5) is fixedly arranged outside the adjusting tube, a swing arm (6) is also hinged on the adjusting tube, and the lower end of the swing arm forms a sliding fit with a slot (8). When the swing arm is arranged in the slot, the distance from the inner side of the bottom surface of the swing arm to a shaft line of a valve body is smaller than the outer diameter of a cylindrical section D2 of the stepped shaft of the valve, and the outer side of the swing arm is in an arc shape. The diameter of an inner hole of the adjusting tube is smaller than the outer edge at the upper end of the stepped shaft of the valve, and the upper end of the valve and the upper end of the adjusting tube are respectively connected with zippers (9), (10) and are respectively connected with a handle.

Description

Sanitary equipment water tank vertical folk art term draining valve

This practicality newly belongs to the draining valve of sanitary equipment water tank.

The common sanitary equipment water tank vertical draining valve that adopts.It has valve member in housing, the valve member lower end is the big float of buoyancy, and the float lower end is a seal gasket.During draining, on the pulling valve member was axial, seal gasket left valve port, and the beginning draining because the buoyancy of float has certain water discharge time, can make the water in the water tank arrange.Its shortcoming is one grade of draining, promptly one is discharged to the end during sanitary equipment cistern water-discharging, opens the water storage of the whole water tank of draining valve and has arranged immediately.But the displacement that people need has nothing in common with each other, and needs displacement many when for example defecating, and only needs a small amount of draining just can satisfy the cleaning requirement during urine.Therefore, this being regardless of needs a draining valve that is flushed to the end, obvious unfavorable conserving water, if huge numbers of families use it, the waste water yield is very considerable.

The utility model purpose provides a kind of sanitary equipment water tank vertical folk art term draining valve, and it can carry out big displacement or two grades of drainings of little displacement according to different needs, selects arbitrarily.

Take technical scheme as follows for achieving the above object:

This sanitary equipment water tank vertical folk art term draining valve.It has housing, guide and valve member, and guide is fixedly mounted on the housing, and valve member is made up of multidiameter and lower end seal gasket.The outside cunning that has an adjustable pipe to be sleeved on a cylindrical section of valve member multidiameter above guide is joined, and can move freely relatively up and down between this cylindrical section of adjustable pipe and multidiameter; In the adjustable pipe fixed outside one water box is installed; One swing arm also is installed on the adjustable pipe; The adjustable pipe diameter of bore is less than valve member multidiameter upper end outer rim; Respectively be connected a slide fastener on valve member upper end and the adjustable pipe, each slide fastener respectively be contained in water tank on handle link to each other.

Be provided with a groove on guide top, swing arm lower end size and this groove cunning are joined, can be along sliding up and down in the groove, and the swing arm lower end is in groove the time, and its inboard, bottom surface should be less than the corresponding cylindrical section external diameter of valve member multidiameter to the valve axis distance, and there is a bigger arc in the swing arm outside.The position of water box on adjustable pipe can be regulated according to instructions for use and determine, fixed installation then.

Advantage of the present utility model:

According to people's different needs, stir handle and spur through slide fastener, can realize big yield draining or little water yield draining.Simple in structure, easy to use, conserve water significantly.

Describe embodiment in detail with reference to accompanying drawing:

Fig. 1 is the utility model closed condition structural representation;

Fig. 2 is a big yield hull-borne structural representation;

Fig. 3 is little water yield hull-borne structural representation;

As shown in Figure 1, be installed with guide 2 on draining valve housing 1, housing inner valve member 3 is made up of multidiameter and lower end seal gasket 7.Multidiameter mainly comprises lower end float D1 and D2 and each cylindrical section of D3.There is adjustable pipe 4 top of guide, and adjustable pipe endoporus and valve member multidiameter cylindrical section D3 are sliding to be joined.Water box 5 and hinged swing arm 6 are installed on adjustable pipe, and swing arm can swing around hinge.Valve member upper end connects slide fastener 9, the adjustable pipe upper end connect slide fastener 10, two slide fasteners respectively be contained in water tank on handle be connected.

This draining valve has three kinds of user modes as follows:

1, as shown in Figure 1, by valve member seal gasket 7, in water tank, not draining is closed condition with water-stop;

2, as shown in Figure 2, by handle pulling slide fastener 9, pulling valve member 3 moves up up to the summit, and valve port is opened draining, until water arrange in the water tank, owing to valve member is conducted oneself with dignity valve member is moved down automatically, seal gasket 7 is shut valve port.Adjustable pipe is together with water box and swing arm transfixion all during this state.This is big displacement state;

3, as shown in Figure 3 little water yield hull-borne is the utility model main innovation part.From closed condition shown in Figure 1, drive slide fastener 10 by handle, pulling adjustable pipe 4 also drives water box 5 and swing arm 6 moves up.Because there is big arc in the swing arm outside, the swing arm lower end can slide in the groove 8 on the guide 2 when moving up.Because of the adjustable pipe upper surface props up the outer rim of valve member upper end, valve member and its are moved on jointly, thereby open the valve port draining.When cistern water level is lower than water box bottom when following, water heavily makes water box, adjustable pipe and swing arm move down together in the water box, swing arm 6 lower ends in groove 8 to lower slider, the shoulder that inboard, swing arm bottom props up multidiameter cylindrical section D2 every, promote valve member 3 and move down close port, but promptly do not wait in the water tank water to put just close port, reach the purpose that conserves water.The water box is installed in the position height on the adjustable pipe, and displacement is little; Otherwise displacement strengthens.So regulate the installation site of water box on adjustable pipe, can control the size of displacement.
