Description

Stainless steel valve control ultrasonic water meter case convenient to assemble

Technical Field

The utility model relates to the field of stainless steel valve-controlled ultrasonic water meters, in particular to a stainless steel valve-controlled ultrasonic water meter shell convenient to assemble.

Background

The ultrasonic valve-controlled water meter generally has two structural forms according to the different relative installation positions of an ultrasonic module (water metering module) and a valve module: the first is that after the valve module is installed on the ultrasonic module, under the structural situation, because the total length of the pipe section of the water meter is limited by the standard specification of the water meter, the valve module occupies the pipe section length, and correspondingly shortens the pipe section length occupied by the ultrasonic module, which leads to shortening of the ultrasonic propagation sound path and further reduction of the ultrasonic metering precision and reliability, and directly influences the performance of the ultrasonic water meter; the second is that the valve module is installed in the middle of two reflecting columns of ultrasonic module, and this kind of structural situation usually needs to cut apart the pipeline section into upstream section, midstream section, downstream section three-section, and wherein an ultrasonic reflecting column is installed respectively to upstream section and downstream section, midstream section installation valve module under this kind of structural style, in order to realize guaranteeing three sections pipeline section leakproofness simultaneously guaranteeing two ultrasonic reflecting columns and just right again, pipeline section processing and assembly degree of difficulty are improved by a wide margin, have directly aggravated ultrasonic valve accuse water gauge's manufacturing cost.

Therefore, valve-controlled ultrasonic water meter cases with externally-arranged valve rods appear on the market to ensure the integrity of the meter cases, but because of the long-time water pressure in the water meter, water can leak if the valve rods are poorly sealed, and the valve rods can be pushed out by the water pressure due to good sealing, so that the valve control is invalid. For example, CN214308933U, the valve rod sleeve is transversely provided with a plurality of mounting threaded holes, the side wall of the valve rod is provided with an annular groove, and the valve rod sleeve are connected by matching the bolts, the mounting threaded holes and the annular groove. Although the problem that the valve rod is separated due to water pressure after being externally arranged is solved, the structure can not provide downward pressing force by utilizing the transverse bolt limit, so that the valve rod has poor tightness; and the annular groove and the installation threaded hole are required to be aligned when the bolt is screwed in, so that the installation difficulty is high.

Because, the stainless steel valve control ultrasonic water meter case is convenient to assemble and stable in structure, the problem to be solved in the industry is urgent.
