Problems solved by technology

However, there are still technical defects in this technical solution: since the floating ball is rotatably connected to the valve body, the movement curve of the sealing plug on the floating ball rocker in the process of blocking the pressure relief port is arc-shaped, while the sealing Both the plug and the pressure relief port are flat, making the sealing not good

Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings.

[0035] Such as Figures 1 to 7 A large flow float switch shown includes a switch body 1 and a float assembly 2. The float assembly 2 includes a float body 21 and a rocker arm 22. The float body 21 is mounted on the rocker arm 22, and the rocker arm 22 is rotatable. Installed on the body 1, the switch body 1 is provided with a valve chamber and a sealing assembly 13 located in the valve chamber, and one side of the switch body 1 is provided with a water inlet and a water outlet communicating with the valve chamber; the sealing assembly 13 is located at the valve The cavity is divided into a first valve cavity on one side and a second valve cavity on the other side; the sealing surface of the sealing assembly 13 can be sealed between the water inlet 111 and the water outlet 112; the other side of the switch body 1 is provided with a drain The pressure hole 121 and the p...

Abstract

The invention discloses a large-flow floating ball switch. By providing a block passage, the motion trajectory of a block is limited to a linear translational motion, and a good blocking effect is achieved. A small-diameter pressure relief hole is blocked by the block, and a sealing diaphragm is pressed against a sealing surface reversely by means of the water pressure of a water inlet, such thatthe need for large flow can be satisfied. An elastic reset member can be used to satisfy the need for small flow by pressing the sealing diaphragm tightly against the sealing surface in case of smallflow and an insufficient pressure difference between left and right chambers.

Description

technical field [0001] The invention relates to a float switch, in particular to a large flow float switch. Background technique [0002] Float switch is a liquid level control device with simple structure and convenient use. It does not need to provide power supply and has no complicated circuit. It has the advantages of smaller volume and longer working life than ordinary mechanical switches. [0003] In the design of the water purifier and the all-in-one drinking water machine, in order to meet the needs of the water production process, a water storage tank will be installed inside it. The liquid level of the water storage tank is controlled by an electronic float switch. Once the electronic liquid level switch fails, the water purifier or the all-in-one water purification machine will keep storing water in the water storage tank, resulting in water leakage and damage to the water purifier or all-in-one water purification machine. machines etc. In order to solve the abo...
