Valve for filling a cistern

Abstract

Valve for filling a cistern, which is equipped with a movable float and in that the unit is permanently installed on a water supply pipe in the cistern, characterized in that a cover part (5) equipped with a permanent or permanent magnet (6) is attached to the up-down limited movable adjustment rod (12, 13, 15), which is movable by a float (11), and in that the cover part (5) or the lever (20) is arranged above the movable magnetizable plate (8) or movable magnetizable bolt (8a), wherein the valve cover (17) forms a contactless separation between the magnets (6) and the parts (4, 7, 8, 8a, 9) installed in the valve housing (2).

Description

[0001] The invention relates to a valve for filling a cistern, which is equipped with a movable float and in which the unit is permanently installed on a water supply pipe in the cistern.

[0002] A float valve of this type is known from the application DE 3153688C2.

[0003] With such a float valve, it is essential that it functions continuously and without problems and that it is protected against evaporated water, which forms a deposit of limescale, but this is not always the case with known designs of the float valve.

[0004] The invention is based on the object of creating a float valve of the aforementioned type which is compact, small and designed to be functionally reliable over a long period of time.

[0005] The problem is solved according to the claims in this application.

[0006] Two embodiments of the invention are explained in more detail below with reference to the drawing.

[0007] They show: Fig. 1 a longitudinal section through a float valve with a movable permanent magnet for moving the magnetizable plate with associated seal which is installed in the valve housing via a sealing membrane. Fig. 2 a longitudinal section through a float valve with a movable permanent magnet for moving the magnetizable bolt with associated seal which is installed in the valve housing via a sealing membrane.

[0008] The Fig. The float valve 1 shown in Figure 1 comprises a valve housing 2 with a thread for connection to the water supply line. The valve housing 2 is designed with an internal drain section 3 over which a diaphragm 4 is placed. A disc 16 with a small hole 16a is installed in the diaphragm 4. A magnetizable plate 8 with a seal 9 is mounted above the disc 16, and both parts 8 and 9 are biased against the cover 17 by a spring 7.

[0009] The parts 4, 7, 8, 9, 16 installed in the housing 2 are tightly covered with a cover 17 in such a way that no element protrudes to the outside for the purpose of performing the function, water flow YES or water flow NO.

[0010] To ensure the water supply is YES or NO, a permanent magnet 6 is installed above the cover 17 in the movable cover part 5. Cover part 5 carries an adjusting rod 12, 13, onto which a float 11 is movably mounted. The movement of parts 5, 12, 13 by path H is determined between the stop 14 and the stop disc 15, and thus the movement of the lifting magnet 6.

[0011] When the float 11 is lowered, the magnet 6 is moved toward the plate 8. The plate 8 is attracted, thus opening the sealed control hole 16a. This releases pressure above the diaphragm, lifting the diaphragm 4 from the drain part 3. The cistern can be filled with water.

[0012] When the float 11 is raised, the holding force of magnet 6 on the plate 8 weakens and is subsequently interrupted. The force of spring 7 pushes the plate 8 toward the control hole 16a and closes hole 16a. The water supply is interrupted.

[0013] The Fig. The float valve 1 shown in Figure 2 has the same features as in the description for Fig. 1. The main difference between the two versions is that a bolt 8a is used instead of the plate 8.

[0014] The advantage of both designs is that there is no tappet, no tappet seal of the valve, for water flow YES-NO, because there are no functional parts leading from the inside of the valve to the outside.

[0015] There is no tappet or tappet seal. This prevents calcification of the external components, and it eliminates the need for long-term cleaning.

[0016] The valve's compact design makes it cost-effective to manufacture and saves space when installed in the cistern. It also saves space in terms of packaging and transport. QUOTES CONTAINED IN THE DESCRIPTION
