Embodiment Construction

[0012] Below the present invention will be further described in conjunction with the embodiment in the accompanying drawing:

[0013] like Figure 1~2 As shown, the present invention mainly includes a valve body 1, a door magnetic switch 3 and a valve core 7, the upper end of the valve body 1 is connected to the valve body joint 2 through threads, and the middle part of the valve body 1 is connected to the door magnetic switch 3.

[0014] The valve body joint 2 is provided with an outlet 4, and the outlet 4 communicates with the valve body 1, and the fluid flows out of the valve body 1 through the outlet 4.

[0015] The valve core 7 is located in the valve body 1 , and a spring 5 is arranged between the valve core 7 and the valve body joint 2 . One end of the spring 5 contacts the valve body joint 2, and the other end contacts the valve core 7. A magnet 6 is arranged between the valve core 7 and the spring 5 .

[0016] The lower end of the valve body 1 is provided with an i...

Abstract

The invention relates to a flow detection switch, particularly to a device for detecting the flow of liquid, and belongs to the technical field of detection. The flow detection switch comprises a valve body, a door contact switch and a valve core, the upper end of the valve body is connected with a valve body connector through threads, and the middle of the valve body is connected with a door contact switch; the valve body connector is provided with an outlet which is communicated with the valve body; the valve core is arranged inside the valve body, a spring is arranged between the valve core and the valve body connector, and a magnet is arranged between the valve core and the spring; the lower end of the valve body is provided with an inlet which is communicated with the valve body. The flow detection switch is small in size and lightweight, avoids metal fatigue and prolongs the service life; a casing is made of metallic copper, so that the flow detection switch has the advantages of being acid-resistant, rust-proof, corrosion-proof and the like and can ensure the capacity for being used in environment with harsh conditions; the structure is simple so that the failure rate and the maintenance rate are reduced; the installation and the maintenance are convenient.

Description

technical field [0001] The invention relates to a flow detection switch, in particular to a device for detecting fluid flow, and belongs to the technical field of detection. Background technique [0002] At present, the common flow detection switches on the market mainly include electronic flow detection switches, piston flow detection switches and baffle type flow detection switches. Although these types of flow detection switches have precise structures and excellent performances, they are expensive, bulky, and difficult to install and maintain. Contents of the invention [0003] The object of the present invention is to overcome the above disadvantages, thereby providing a flow detection switch, which uses a door magnetic switch to control the flow in and out, low cost, small size, light weight, and easy to install. [0004] According to the technical solution provided by the present invention, the flow detection switch includes a valve body, a door magnetic switch and...
