Abstract

The utility model relates to a watertight soft siphoning type drain valve for a toilet cistern. The utility model is characterized in that a drain valve body is made of an elastic corrugated hose which is easy to telescope. An overflow tube, a valve and a siphon tube are combined into a whole. The inlet of the utility model is provided with screw thread, so the drained water has vortices. A control button is controlled by a bracing cable to steplessly regulate water drainage. The utility model has the advantages of less noise, fast water drainage, large water flushing power, long service life, water saving, less failure and little space occupation. The utility model is suitable for renewing the existing drain valve for a toilet cistern and is suitable for matching with the toilet cisterns of apartments, dwellings and guesthouses.

Description

The water-tight closet sanitary equipment of soft hydrocone type draining valve

The utility model belongs to the daily-use sanitary equipment part and relates to closet sanitary equipment device.

Now use closet sanitary equipment device as shown in Figure 1: form by water intaking valve 1, draining valve 2, ball float 3, drain elbow 4, overflow pipe 6, opener 6 and water tank 7.Wherein the structural shape of draining valve and existing problems are as follows:

1. old-fashioned draining valve shown in Figure 2 is owing to discharge water that process rubber globe valve blocks to fall easily aloft or the rubber globe valve falls to misaligning just to cause with valve seat and leaks.

2. Figure 3 shows that the turnover plate type draining valve of 87 years GBs, though can not take place to block and misalign phenomenon as Fig. 2 is the sort of, but because deadweight is little, incipient stage valve closing blow-by meeting in water inlet is leaked, could seal water-tight when only after cistern water level arrives certain altitude, certain water pressure being arranged, and the current of the process that discharges water cistern water-discharging are that axle is asymmetric, thus in-fighting to cause bath power be not maximum.

3. Figure 4 shows that the hydrocone type draining valve that stereoplasm tube is made, it relies on hand to be pulled upwardly the interior slim piston of large diameter cylinder, allow bend pipe all be full of water and realize the siphon condition, the height of this kind hydrocone type gutter will exceed the diameter that the cistern water level height adds bend pipe, though good seal can not leak yet, water level to be raise earlier during draining and reduce again, wasted energy, cause bath power owe big and discharge time longer, especially the volume of draining valve own very main point account in the water tank than large space.

The utility model purpose is the shortcoming that will overcome prior art, provides water-tight, simple in structure, accounts for the little and easy to use and reliable closet sanitary equipment draining valve in water tank space.

For achieving the above object, adopt following technical proposals:

This closet sanitary equipment draining valve is to be made of the corrugated flexible pipe that favorable elasticity is arranged.Be connected with control knob behind the pulley on the fixed guy cable rounds draining valve base in flexible pipe upper end, the place's sealing of flexible pipe bottom is installed.

Control knob pulling drag-line can make the bottom of hose bending to closet sanitary equipment water tank, realizes having the hydrocone type draining of big flushing ability.Only need loose one's grip towards the intact back of Xian, mat flexible pipe elasticity makes drag-line get back to original position, and flexible pipe returns to vertical shape, and the entrance, upper end exceeds the water surface.So only otherwise the pulling rope, must guarantee unlikelyly to leak from gutter.Because the pulling drag-line is changeable, optionally realizes the step-less adjustment draining easily, help water saving.

The drawing explanation:

Fig. 1 is the structural representation of prior art closet sanitary equipment device;

Fig. 2 is a rubber ball valve vertical draining valve;

Fig. 3 is a rubber turnover panel rotary type draining valve;

Fig. 4 is a rigid plastics inverted U pipe hydrocone type draining valve;

The structural representation that Fig. 5 implements on the horizontal water tank of water closet for the utility model, wherein Fig. 5 a is an elevation, Fig. 5 b is the sectional view of bowing;

The structural representation that Fig. 6 implements on the vertical water tank of water closet for the utility model, wherein Fig. 6 a is an elevation, Fig. 6 b is the sectional view of bowing;

The structural representation that Fig. 7 implements on the water tank of high position, public lavatory for the utility model.

Embodiment with reference to description of drawings this programme:

Example 1:

Be shown in this draining valve of installation in the horizontal toilet water tank as Fig. 5 a.A rim of a cup 1 is adorned in entrance, draining valve top, is thread-shaped pipeline section 2 below the rim of a cup, and its surfaces externally and internally all is thread-shaped, makes in the water tank water enter that end entrance promptly produces vortex on the draining valve, favourable raising drainage efficiency and flushing ability.At screw thread pipeline section 2 but the buoyancy aid 3 that moves along the screw thread up-down adjustment is housed, this buoyancy aid helps draining valve main body (flexible pipe) 4 to be accelerated vertically.Draining valve main body 4 is the good corrugated flexible pipe of elasticity, it be positioned at thread-shaped pipeline section 2 below, its tube wall cross sectional shape is shown in A among Fig. 5 a, triangular in shape, or be trapezoidal or be circular arc, this flexible pipe bottom installed surface has the sealing ripple, to guarantee the sealing of installation place, bottom.The control knob 5 that is installed in the water tank side connects drag-line 6, and the pulley 8 on the guy cable rounds draining valve base 7 is fixed with draining valve upper end buoyancy aid 3.

Example 2:

As shown in Figure 6, for being used for the draining valve of vertical tank for excrement pan.The basic structure scheme is identical with example 1.Difference mainly is that control knob 5 is installed in tank top.

Example 3:

As shown in Figure 7, be the draining valve of the high position water tank that is used for the public lavatory, the basic structure scheme is identical with example 1.Its difference is the drag-line control knob 5 on the water tank of high position, by backguy 9 controls of hanging.

Remarkable advantage of the present utility model:

The draining valve main body i.e. easy flexible crooked elastic corrugated shape flexible pipe, melts draining valve, excessive water Pipe and siphon pipe three are integrated. Structure is very simple, and is cheap, easy for installation, make With reliably, thoroughly solved the drawback that the tank for excrement pan draining valve easily leaks.
