Float inlet valve

Abstract

The invention discloses a floating ball water inlet valve. The floating ball water inlet valve comprises a shell, a float, a connecting rod, a water sealing connecting rod, a sealing body, a sealing body seat, a water outlet nozzle, a fixing device, a water inlet pipe and a water outlet pipe, wherein the water inlet pipe is provided with a water outlet end fixedly communicated with the water outlet nozzle; one end 51 of the connecting rod is fixedly connected with the float and the other end 52, opposite to the end 51, of the connecting rod is fixedly connected with the water sealing connecting rod; the sealing body is sealed with the water outlet nozzle in a matching mode and fixed on the sealing body seat; the fixing device is arranged on the water inlet pipe; the shell is provided with an inner cavity, a first channel, a second channel and a water outlet which are communicated with the inner cavity; the first channel and the second channel are coaxially and parallely arranged; the first channel matches with the water inlet pipe and is fixedly connected with the water inlet pipe in a sealing mode; the second channel matches with the sealing body seat; a hinging support hole and a limiting surface are disposed on the outside of the shell under the second channel; the water sealing connecting rod is a stainless steel plate, stamping part and in an F shape, the upper end of the water outlet pipe fixedly connected with the water outlet, and the lower end of the water outlet pipe extends downwards. The floating ball water inlet valve is simple in structure and suitable for various water supplying devices.

Description

technical field [0001] The invention relates to a ball float water inlet valve, in particular to a ball float water inlet valve used in various water supply devices. Background technique [0002] In the prior art, the water replenishment control of the water dispenser adopts the float ball inlet valve to control the water replenishment liquid level, including the shell, the exhaust hole, the water inlet pipe, the float ball and the water outlet hole arranged at the bottom of the shell, and the characteristic is that the water inlet pipe It is installed on the upper part of the shell, and the water inlet valve is set at the water inlet, and the lever is set under the valve core. One end of the lever is connected to the floating ball through the ejector rod, so that the water level of automatic water replenishment is stable. The water inlet valve is hinged on the casing. The connecting rod is connected to the floating ball to complete the control action. When the floating ball...

AI Technical Summary

Problems solved by technology

The disadvantages of the above technology are: on the one hand, the sealing member moves in a circular arc along with the connecting rod hinged on the casing, and the water outlet of the water inlet pipe must be installed on the tangent of the circular arc to ensure that the floating ball rises to the predetermined liquid level. The seal seals the outlet nozzle of the water inlet pipe, which requires high installation accuracy between the outlet nozzle of the water inlet pipe and the hinged position. When the error of the hinged hole becomes larger during use, it is easy to change the center of the arc and cause a seal Parts failed to seal the spout, reducing the service life; on the other hand, when the water dispenser of the prior art replenishes water, it is directly sprinkled in the water dispenser from the spout, and poured on the horizontal surface, so that the water in the original water dispenser There is no separation between the heated and sterilized water and the added water, which makes the water temperature and quality of the water dispenser unstable
