Abstract
The utility model provides a low-cost electromagnetic water meter shell structure with a one-way valve, which comprises an electromagnetic water meter shell body, a shell sealing upper cover, a sealing gasket, a limiting flow guide screw and a sealing steel ball, wherein the electromagnetic water meter shell body is provided with an air guide groove; the sealing steel is arranged in a gas guide groove of the electromagnetic water meter shell body; the outer layer of the sealing steel ball needs to be coated with sealing grease; the limiting diversion screw is in threaded connection with a gas guide groove arranged on the electromagnetic water meter shell body; a sealing gasket is arranged between the upper sealing cover of the shell and the shell body of the electromagnetic water meter and is connected with the upper sealing cover of the shell and the shell body of the electromagnetic water meter through threads; the structure forms an electromagnetic water meter shell with a one-way valve after being assembled for testing the air tightness of the shell, and the shell can maintain pressure after a pressure pipe is removed by one-time pressing, so that the purpose of detecting the air tightness by soaking water in batches under the pressure maintaining condition is realized.
Description
Technical Field
The utility model relates to the field of electromagnetic water meters, in particular to a low-cost electromagnetic water meter shell structure with a one-way valve, which is mainly used for testing the air tightness of a shell.
Background
The electromagnetic water meter has diversified application occasions, particularly the electromagnetic water meter and the flowmeter which are arranged in a water meter well, the waterproof performance of a meter body is challenged, air tightness detection is generally carried out when the electromagnetic water meter leaves a factory, a pressure pipeline is connected with a shell to press a hole, bubble water is tested under pressure to observe whether bubbles leak, a ventilation hose is generally connected with the method, only 1 meter is detected once, and the efficiency is low during batch production. Aiming at the phenomena, a pressure opening structure with a one-way valve is developed on the basis of the electromagnetic water meter shell.
Disclosure of Invention
The utility model provides a low-cost electromagnetic water meter shell structure with a one-way valve, which is used for testing the air tightness of a shell.
In order to achieve the above object, the technical solution of the present invention is as follows:
the utility model provides a low-cost electromagnetism water gauge shell structure of taking check valve, contains electromagnetism water gauge shell body, the sealed upper cover of casing, sealed pad, spacing water conservancy diversion screw, sealed steel ball, characterized by: the electromagnetic water meter shell body is provided with an air guide groove; the sealing steel is arranged in the gas guide groove of the electromagnetic water meter shell body; the outer layer of the sealing steel ball needs to be coated with sealing grease; the limiting diversion screw is in threaded connection with a gas guide groove arranged on the electromagnetic water meter shell body; a sealing gasket is arranged between the upper sealing cover of the shell and the shell body of the electromagnetic water meter and is connected with the upper sealing cover of the shell through threads; and the structural part forms an electromagnetic water meter shell with a one-way valve after being assembled.
The utility model has the beneficial effects that:
(1) the utility model relates to a low-cost electromagnetic water meter shell structure with a check valve, which solves the problem of efficiency of shell air tightness test, a simple special check valve structure is added at a pressurizing port, and the pressurizing pipe can be directly pulled off after inflation.
(2) The electromagnetic water meter shell structure with the one-way valve is low in cost, operation difficulty of a production line for detecting air tightness of the electromagnetic water meter is reduced, and the one-way valve is simple in structure and easy to process and assemble.
Drawings
FIG. 1 is a schematic structural diagram of a low-cost electromagnetic water meter case with a check valve according to the present invention.
Detailed Description
The technical solution of the present invention will be described in further detail with reference to the following description of the embodiments and the accompanying drawings.
As shown in figure 1:
a low-cost electromagnetic water meter shell structure with a one-way valve comprises an electromagnetic water meter shell body (3), a shell sealing upper cover (1), a sealing gasket (2), a limiting diversion screw (4) and a sealing steel ball (5),
the electromagnetic water meter shell body is provided with an air guide groove;
the sealing steel is arranged in a gas guide groove of the electromagnetic water meter shell body;
the outer layer of the sealing steel ball needs to be coated with sealing grease;
the limiting diversion screw is in threaded connection with a gas guide groove arranged on the electromagnetic water meter shell body;
a sealing gasket is arranged between the upper sealing cover of the shell and the shell body of the electromagnetic water meter and is connected with the upper sealing cover of the shell through threads;
the structural part forms an electromagnetic water meter shell with a one-way valve after being assembled.
The assembly process and the working principle of the utility model are as follows:
coating sealing grease on the outer layer of the sealing steel ball, placing the sealing steel ball into the air guide groove, screwing the limiting guide screw, pressing the sealing gasket, screwing the shell sealing upper cover, forming a sealing cavity in the shell at the moment, when the shell is inflated by the air inlet, the sealing steel ball can be jacked up due to pressure difference, gas can pass through the periphery of the sealing steel ball and then enter the shell through the limiting guide screw, pulling out the inflation inlet after the air pressure reaches balance, and the steel ball can be pressed in the lower conical groove under the action of gravity and gas pressure to play a single-item conduction and sealing role.
10 sample machines are manufactured according to the structure, and the functions of the sample machines meet the requirements after multiple practical operation tests.
