Abstract

The invention belongs to the technical field of water meters, and relates to a water meter executing mechanism flow valve sealing structure which comprises a water meter shell, an executing mechanism, a flow valve and a flow valve rod. When the executing mechanism is installed on the upper side of the bottom face of the water meter shell in a buckled mode, the second annular boss is pressed downwards to root grooves of the first annular boss and the third annular boss, the third annular boss is pressed upwards to root grooves of the second annular boss and the fourth annular boss, and a first sealing ring is arranged on the table face of the second annular boss. A second sealing ring is arranged on the surface of the third annular boss; the problem that water seeps into the water meter shell from the flow valve rod is solved in a multi-period and multi-structure mode through primary water prevention, secondary sealing and tertiary sealing, and it can be ensured that the product is fully dampproof and waterproof.

Description

technical field [0001] The invention belongs to the field of water meters, and relates to a sealing structure of a flow valve of an actuator of a water meter. Background technique [0002] The actuator of the water meter is used to connect and control the flow valve of the water meter to remotely open or close the water flow of the water meter. The actuator of the water meter is located in the water meter shell and connected to the water meter flow valve. The outer shell extends into the water meter shell and is finally connected to the water meter actuator to realize that the actuator opens or closes the flow valve. However, due to the gap between the flow valve stem and the flow valve, the water flow in the water meter often overflows from the gap between the flow valve and the flow valve stem and enters the water meter case through the flow valve stem, resulting in the circuit and related components in the water meter case. Moisture damage. How to prevent the overflowin...
