Filtering clamping type glass rotameter

Abstract

The invention relates to a filtering clamping type glass rotameter which comprises a water outlet tube, a water outlet channel, an upper clamping component, a conical glass scale tube, a water inlet cavity, a flow regulating cavity, a water inlet tube, a water outlet glass sealing washer and a water inlet glass sealing washer. The upper clamping component and a lower clamping component are respectively arranged at the positions of an upper end opening and a lower end opening of the conical glass scale tube, wherein the upper clamping component is arranged in a groove at the thickness center of the water outlet glass sealing washer at the upper end of the conical glass scale tube, and the lower clamping component is arranged in a groove at the thickness center of the water inlet glass sealing washer. In the invention, the sealing washers at the positions of the upper end opening and the lower end opening of the conical glass scale tube of a small filtering type glass rotameter are slightly improved, and the clamping components are additionally arranged, thereby solving the problem that in the operating process of the rotameter, the inside of a stainless steel floater and the conical glass scale tube scales because of poor water flow control or poor water quality, which causes the stainless steel floater to be clamped at the positions of the upper end opening and the lower end opening of the conical glass scale tube.

Description

technical field [0001] The invention relates to a glass rotameter, in particular to a glass rotameter capable of preventing stainless steel floats from being stuck at the upper and lower ports of a tapered glass scale tube. Background technique [0002] Glass rotameters are widely used in chemical industry, petroleum, light industry, medical treatment, chemical fertilizer, food, papermaking, environmental protection and synthetic fiber, scientific research and other units. It is a high borosilicate tapered glass scale tube and a stainless steel float that can float up and down in the tube. When the fluid flows through the tapered glass scale tube from bottom to top, a pressure difference is generated between the upper and lower sides of the float, and the float rises under the action of this pressure difference. . When the rising force is equal to the gravity of the float, the float is in a balanced state. Therefore, there is a certain proportional relationship between the ...

AI Technical Summary

Problems solved by technology

[0003] The present invention aims to solve the technical problem that the floater is stuck due to the flow rate of the fluid medium in the system being too large or too small during the operation of the existing glass rotameter, and provides a filter stop glass rotameter , the flowmeter can slightly improve the inlet and outlet water glass sealing gaskets at the upper and lower ports of the tapered glass scale tube without changing the flow characteristics of the measured fluid, and add upper and lower clamping elements to prevent the float from being stuck. The effect of two ports above and below the tapered glass graduated tube
