Description

Sealing structure of valve-controlled water meter electronic module

Technical Field

The utility model relates to a valve accuse water gauge field specifically is a valve accuse water gauge electronic module's seal structure.

Background

Since the valve-regulated water meter is often installed in a wet environment, the electronic module of the valve-regulated water meter needs to have good water resistance. However, most of the similar water meters on the market have the problems of poor sealing performance or poor reliability, and the main reason is that the sealing between the valve and the electronic module shell is difficult. In the prior art, only the O-shaped ring on the valve rod is used for waterproof sealing (see figure 1), and the valve rod needs an actuator (a motor) to drive the valve rod to rotate, so that the torsion of the actuator is not reduced, only the O-shaped ring with a small compression amount can be selected, and the sealing effect is poor.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a valve accuse water gauge electronic module's seal structure to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: a sealing structure of a valve control water meter electronic module comprises an actuator, an electronic module shell, a sealing assembly, a valve rod and screws, wherein an inwards concave mounting part is arranged on the electronic module shell, the actuator is matched with the mounting part, the end part of the actuator is assembled on the inner side of the mounting part through four screws, and epoxy resin is filled in assembling gaps around the actuator and the electronic module shell; the sealing assembly is arranged between the actuator and the electronic module shell and comprises a double sealing ring structure and sealing grease; the valve rod is assembled below the actuator and can rotate freely.

Preferably, the joint of the valve rod and the actuator is filled with sealing grease, and the sealing grease is used for blocking external moisture from entering the interior of the actuator.

Preferably, the double-sealing ring structure comprises a flat gasket and an O-shaped sealing ring, wherein the flat gasket is arranged between the electronic module shell and the actuator and is used for preventing epoxy resin from overflowing.

Preferably, the O-shaped sealing ring is arranged on the valve rod, and the O-shaped sealing ring prevents external moisture from entering and prevents sealing grease from losing.

Compared with the prior art, the beneficial effects of the utility model are that:

compared with the prior art, the utility model has better waterproof performance and simple structure, and is convenient for replacing and maintaining the electronic module of the water meter; the electronic module is sealed in multiple modes of epoxy resin, sealing grease and sealing rings, so that the electronic module can be used for a long time under severe environmental conditions and even underwater without water seepage, and has good reliability.
