Detailed Description

The following describes preferred embodiments of the present invention in detail with reference to the accompanying drawings.

As shown in fig. 1, a remote control float valve comprises a main valve body 1, a water inlet pipe 2, a water outlet pipe 3, an upper valve body 4 and a float ball pilot valve assembly 5. The valve cavity is arranged in the main valve body 1 and comprises an upper valve cavity 11 and a lower valve cavity 12, the upper valve cavity 11 and the lower valve cavity 12 are separated by a partition plate 6, a through hole 7 is formed in the partition plate 6, and a first valve core 8 is arranged at the through hole 7. One side of the main valve body 1 is provided with the water inlet pipe 2, and the water inlet pipe 2 is communicated with the lower valve cavity. The other side of the main valve body 1 is provided with the water outlet pipe 3, and the water outlet pipe 3 is communicated with the upper valve cavity 11. Water enters the valve cavity from the water inlet pipe 2 and flows out from the water outlet pipe 3, and when the water pressure of the water inlet pipe 2 is small, water flow is blocked in the water inlet pipe 2 by the first valve core 8. The main valve body 1 is provided with the upper valve body 4, an auxiliary valve cavity 41 is arranged inside the upper valve body 4, and a second valve core 9 is arranged in the auxiliary valve cavity 41. The second valve core 9 is connected to the first valve core 8 through a connecting rod 10, the first valve core 8 is fixed at the bottom end of the connecting rod 10 through a lower nut 17, the second valve core 9 is fixed at the top end of the connecting rod 10 through an upper nut 16, a guide sleeve 18 is arranged below the upper valve body 4, the connecting rod 10 is arranged in the guide sleeve 18 in a sliding mode, a rubber ring 19 is arranged in the connecting rod 10 and the guide sleeve 18, and a spring 13 is arranged on the connecting rod 10. The auxiliary valve chamber 41 is communicated with the water inlet pipe 2 through a first connecting pipe 14, a manual ball valve 20 is arranged on the first connecting pipe 14, and the valve is controlled to be opened through the manual ball valve 20. The auxiliary valve cavity 41 is communicated with the floating ball pilot valve assembly 5 through a second connecting pipe 15, and an electromagnetic valve 21 is arranged on the second connecting pipe 15, so that electric control is realized.

In the utility model, the floating ball pilot valve assembly 5 comprises a connecting sleeve 51, a plunger rod 52, a top rod 53 and a floating ball 54; the connecting sleeve 51 is disposed at the water outlet of the second connecting pipe 15, the plunger rod 52 is slidably disposed in the connecting sleeve 51, one end of the plunger rod 52 abuts against the water outlet of the second connecting pipe 15, the other end abuts against the ejector rod 53, and the ejector rod 53 is connected to the floating ball 54.
