A shaft (5) is attached to the lever part @ (3) which is attached to the main body (4) so as to extend diagonally forward and downward. A float (1) is provided.

Therefore, in this conventional water tank ball tap, the buoyant force of the float is in the opposite direction (6) with respect to the axis of the shaft rod! When the bamboo valve is closed, excessive force is applied to the 111 rod, and the roots of the shaft rod and the float are likely to break.

It is an object of the present invention to solve the above-mentioned problems and to prevent the 11 rods from breaking even if excessive force is prevented from being applied to the shaft rods.

In order to achieve the above object, the present invention has a pilot-type water tank pole tag, which is equipped with a pilot valve in the main body that is opened and closed by a float floating in water, in which the rear part is attached to the main body. A pilot valve body is provided at the rear end of the lever system in front, and a mounting portion is provided at the front of the lever member, and a shaft rod protruding from the top surface of the float is attached to this mounting portion. The Ill wire is installed so that it faces vertically when the pilot valve is closed, and the float is placed in the upper direction.

The float (1) has a bottomed cylindrical main body (
1a) and a lid part (1b) for sealing the i=I opening of the main body part (1a), both of which are each made of synthetic resin and joined together by a bath coat.

The body part (1a) and the lid part (1b), which were more protruding and shaped in the last ARS notification il + 40, have one side attached to the periphery of the body part (1a) and the lid part (1b), which are combined and extend all the way around the blood. A concave groove @ is formed on the other side, and a convex line (B) that engages with the recess (C) is formed on the mating surface of the other side, and these concave grooves and convex line (B) are engaged to form a super 1 By aligning the waves, the main body (la) and the lid (1b) are integrally aligned.

Here, I will briefly explain the ultrasonic V-junction method.

Figure 6 shows a schematic diagram of the ultrasonic bonding device, in which (c) is an ultrasonic oscillator connected to a power source, and (c) is an ultrasonic wave generator that transmits ultrasonic vibrations from the ultrasonic wave oscillator in the vertical direction. A transducer that converts into ultrasonic vibrations, (G) is a cone that expands the amplitude of ultrasonic vibrations from the transducer (C), 0η is a horn that is integrally attached to the cone, and 9'4 is located on the lower side. The lid part (lb) is placed in an anobile in a fixed state.

To weld the lid part (1b) to the main body part (la), operate the ultrasonic oscillator (c) while applying a predetermined pressure with the air cylinder C31 on the upper side, and the tip of the horn 0 will be attached to the bath. Vibrates with the necessary amplitude, and ultrasonic vibrations are applied to the main body i! +1

Providing the riff (7) on this body is cheaper than increasing the thickness of the entire lid (lb), and is cheaper in terms of cost. lb) does not stop hanging and does not absorb the buoyancy of float (1).

Incidentally, the reinforcing rib (7) may be provided protruding from the bottom side and connected to the shaft rod (5).

Therefore, the float (1) is made by layering the shaft rod (5) on the female screw (4a) of the lever system (3), so that the distance between the float (1) and the lever wing (3) is 1 inch. Attach it to the lever member (3) so that you can freely view the coldness of the water surface when the water is stopped.

Note that the shaft rod (5) can be attached to the lever member (3) in any manner. For example, as shown in FIGS. 7 to 8, the attachment part (4) is formed at the tip of the lever member (3). In addition to providing a square column part (4b), a plurality of square hole parts (5a) into which the square column part (4b) fits are provided in the 4411 rod (5) at appropriate intervals, and the square hole part (5a) is inserted into the appropriate square hole part (5a).

On the other hand, the upper royal valve body θ・9 is formed by the diaphragm member, and the step part (13) and the opening ↑1130υ inner curve (1
The peripheral part and the central part which are folded by fJ are formed in the thickness, and the current part which is folded by Jewaka 15 is formed thin so that it is easy to deform. ] ``It's A7, which has a concave shape around the Fort.

~Ma/ζ, the thick inner part of the central part of the main valve body Ql is supported from the dorsal side by the receiving kl plate and is quadrupled on the king-jp 04h] The pressure chamber (11) and the main flow passage (1st primary A small hole-shaped passage ψ is provided between the side and the n f1 side.

In addition, 4 in the figure is a cleaning pin (14) installed on the inner surface of the small passage (241) that loosely fits between the small passages (241 and 241) and prevents dirt and limescale from clogging the small passage Q-9.

The operation of the auxiliary ball tap is basically the same as that of a conventional pilot-type hole tap, and when the float (1) lowers due to a drop in the water level in the water storage slide, the kllF 2 )

h ,,,k −'m (J −?+f open, pressure chamber μ
The water in η is discharged J, lt'.

Therefore, the main Mt, path (11#-next pressure is pressure chamber αη
This pressure pushes the main valve body (14) away from the main valve seat 04, opening the main valve (b), and the water t on the next side flows to the secondary side, and the outflow part ( 9).

When the float (1) rises due to the rise in the water level in the water tank, the lever member (3) shifts upward and the axis of the shaft rod (5) of the float (1) rotates approximately 1μ vertically. Pilot valve (
When a) is closed, the volume of the pressure chamber α increases due to water flowing into the pressure chamber (17) from the small passage leakage 9, causing the main valve body θ◆ to flutter. Valve (b) closes to stop water supply. At this time, the buoyancy of the float is at its maximum, and the buoyancy is concentrated on the root of the rod and the float, but the buoyant force acts in the axial direction of the rod, and the buoyancy is the force that bends the root. It does not work, and since the root part is reinforced with 110-strong ribs, the root part will not dent.

Since the present invention has the above-mentioned 414 structure, it has the following advantages.

(1) A shaft rod is installed vertically in the middle part of the upper surface of the float, and this shaft rod is connected to its il, III? Since fM is attached to the tip of the lever so that it faces the b: 6 my its: direction when the pilot valve is closed, the buoyancy of the lever is Q + l + 1 of the rod.
1! I11 The roots of the floats and shaft rods will never break, as they should not work against the sword.

(The buoyancy of the 2nd float is 11111 '91 of the 14 descendant part)
Concentrate on the +, but in the 3rd and 11th cities, put the tribute S on the center line and block the direction VC, and put the sleeve 5 insect rib purple set on the center t (so, I A '714! There is no risk of cracking or denting.

In addition, since it is reinforced with reinforcing lip, the thickness of the whole area is reduced.
This is cheaper than increasing the speed and strength, and the weight of the lid does not increase unnecessarily, nor does it reduce the buoyancy of the float.

(3) Since the float is made of two parts, the main body and the lid, divided by 14, it is necessary to provide 111 flea ribs on the A part, and the main body and the lid are made of synthetic resin. Since both parts are welded together, the float can be completely sealed and hollow.
