Further, as described in the back of the inlet and outlet, respectively set up the first cover mounting bracket and the second cover mounting bracket, described the first protective cover mounting bracket mounting bracket and two, respectively, set up and the first top and the second top reinforcement, described the first cover mounting bracket and the second cover the interior of the mounting bracket are embedded within the fourth thread copper pieces.

Further, the valve structure of the water meter suitable for ultrasonic testing is made of the following mass fraction of raw materials: 100 matrix resin; Masterbatch 3-8 parts; 1-3 portions of antifoaming agent.

A water meter valve structure processing technology suitable for ultrasonic detection, including the following steps:

 I Weighed the raw materials according to the proportion, stirred them evenly in the mixer, and pumped them into the hopper of the granulator under the action of the pumping system;

Ⅱ granulator extruding granulation, granulation material access to the storage tank, dry 4-8h;

Ⅲ. The dried granulated material is added into the hopper of the injection molding machine, and the molten material is preheated into the flowing state;
