Embodiment 1

[0028] like Figure 1 to Figure 6 As shown, the present embodiment is a display for the pressure range of a fire extinguisher, including a spherical transparent shell 1, a spherical inner shell 2 inside the transparent shell and concentric with it; the inner diameter of the transparent shell is 1- 2mm.

[0029] One end of the transparent shell is open, and an outer tube 11 is fixedly connected to the opening, and an annular plate 111 is integrally formed on the end of the outer tube away from the transparent shell.

[0030] The inner shell 2 is formed with two symmetrical mouths along two ends of the same diameter, and an inner tube 21 is fixedly connected to the inner side of one of the mouths, and the other end of the inner tube runs through the other mouth; the inner tube runs through the outer tube; One end of the inner tube outside the shell is threadedly connected with a connecting cap 3, and the connecting cap is integrally formed with a connecting pipe 31 connected wi...

Embodiment 2

[0043] A display for the pressure range of a fire extinguisher comprises a spherical transparent outer shell, a spherical inner shell inside the transparent outer shell and concentric with it; the inner diameter of the transparent outer shell is 1-2mm larger than the outer diameter of the inner shell.

[0044] One end of the transparent shell is open, and an outer tube is fixedly connected to the opening, and an annular plate is integrally formed on the end of the outer tube away from the transparent shell.

[0045]The inner shell is formed with two symmetrical mouths along two ends of the same diameter, and an inner tube is fixedly connected to the inner side of one of the mouths, and the other end of the inner tube runs through the other mouth; the inner tube runs through the outer tube; the inner tube One end of the pipe outside the casing is threadedly connected with a connecting cap, and the connecting cap is integrally formed with a connecting pipe connected with the fire...

Abstract

The invention discloses a pressure indicating liquid anti-mixing device of a fire extinguisher. The pressure indicating liquid anti-mixing device comprises a spherical transparent outer shell and a spherical inner shell in the transparent outer shell; and one end of the transparent outer shell is fixedly connected with an outer pipe, and an annular plate is integrally formed at one end of the outer pipe away from the transparent outer shell. The inner shell is fixedly connected with an inner pipe, and one end of the inner pipe penetrates through the inner shell; the inner pipe penetrates through an outer pipe; and a second constant pressure spring, a first constant pressure spring and an annular piston are sequentially connected inward to an inner side of the annular plate. A first anti-mixing device is installed in the outer tube, and a second anti-mixing device is installed in the inner pipe. A closed liquid storage cavity is formed among a cylindrical piston, an inner wall of the inner pipe, a threaded passage, the inner wall of the transparent outer shell, an outer wall of the inner shell, the inner wall of the outer pipe, a bent passage and an annular position; and the liquidstorage cavity is filled with yellow indicating liquid, green indicating liquid and red indicating liquid in sequence from the cylindrical piston to the annular piston. By means of the two anti-mixingdevices, the indicating liquid of different colors can be prevented from being mixed together.

Description

[0001] This application is the application number: 201711425099X [0002] The name is: A fire extinguisher pressure range display [0003] The application date is: 2017-12-25 [0004] divisional application. technical field [0005] The invention belongs to the field of fire extinguisher pressure gauges, in particular to a fire extinguisher pressure indicating fluid anti-mixing device. Background technique [0006] Because the surface of the barometer of the current fire extinguisher is on a vertical plane, it is very troublesome to check the fire extinguisher placed on the ground and in the box. You have to squat down, and even take the fire extinguisher out of the box and turn it to see it. to the indication of the barometer. This is very laborious and time consuming. The applicant's application number is 201711425099X, and the invention patent named a fire extinguisher pressure range display solves the above problems, but also encounters a new problem. If the fire ext...
