Embodiment Construction

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0031] see Figure 1-6, the embodiment of the present invention provides a technical solution: a stainless steel water meter casing and its processing method, including a main casing 1, a secondary casing 2, a water inlet pipe 3 and a water outlet pipe 4, and the water inlet pipe 3 and the water outlet pipe 4 are far away from the water meter One end of the housing is connected with a connecting block for easy connection with the external water pipe. The inner...

Abstract

The invention discloses a stainless steel water meter casing and a processing method thereof, comprising a main casing, an auxiliary casing, a water inlet pipe and a water outlet pipe, the inner cavity of the main casing communicates with the inner cavity of the auxiliary casing, the inlet The inner cavity of the water pipe is provided with an expansion cavity, and the inner cavity of the expansion cavity is fixedly connected with a first pull rope. The present invention relates to the technical field of water meters. In the stainless steel water meter casing and its processing method, when the water flow enters the inside of the water meter casing through the water inlet pipe, the floating ball drives the sealing plate to move upward under the buoyancy of the water, the sealing plate is separated from the fixed ring plate, and the floating ball passes through the fixed ring. The sealing plate and the sealing plate are located in the expansion chamber under the action of the first pull rope, which reduces the resistance of the water flow. When the water flow reverses, the sealing plate is tightly pressed on the fixed ring plate, and the floating ball is pressed on the ball groove to ensure the water flow. Unable to reverse flow, which solves the problem that the common water meter shell itself cannot realize the function of preventing water reverse flow, and the one-way valve has a large resistance to water flow.

Description

technical field [0001] The invention relates to the technical field of water meters, in particular to a stainless steel water meter casing and a processing method thereof. Background technique [0002] Existing water meters are instruments for measuring water flow. Most of them measure the cumulative flow of water. They are generally divided into two types: volumetric water meters and velocity water meters. The development of water meters has a history of nearly 200 years. When selecting water meter specifications, you should First estimate the size and flow range of the flow normally used, and then choose the water meter with the specification that the common flow is closest to the value as the first choice. [0003] The water volume calculation device is installed in the water meter case, which mainly plays the role of calculating the water consumption of the user each time. This is based on the premise that the water flows in one direction. If the water flows in the oppos...
