A strip valve tray for preventing valve sticking

Abstract

The invention discloses a strip-shaped float valve tray for preventing the sticking of float valves, which comprises a float valve tray plate body, a float valve hole is opened on the float valve tray plate body, and a strip-shaped float valve is arranged in the float valve hole. The strip float valve includes a rectangular bonnet and two valve legs. A sliding groove is provided on the side wall of the connection between the tray body of the float valve and the valve leg of the strip float valve, and a miniature sliding roller is connected to the sliding groove in rotation. The invention avoids rusting or adhesion between the valve leg and the side wall of the float valve hole, ensures the normal opening and closing of the strip float valve, improves the efficiency of the tray, and reduces the strip float valve being blocked by the second spring. The degree of inclination when blowing makes the bubbling smooth, so that the whole process has a buffer, increases the contact time of gas and liquid, and improves the mass transfer efficiency.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a strip-shaped float valve tray for preventing the sticking of float valves. Background technique [0002] According to the bubbling elements, the trays mainly include bubble cap type, sieve hole type, float valve type, inclined hole type and other special types of trays. Floating valve tray is to open valve holes on the tray, and install valves that can float up and down (except fixed valves). Since the gas circulation area of ​​the valve tray can be automatically adjusted with the change of the gas load, it can maintain stable operation under a wide gas load; at the same time, the gas is blown out in the horizontal direction, the gas-liquid contact time is long, and the entrainment of mist is small, which has good performance. The operating flexibility and high tray efficiency have been widely used in industry. [0003] Nutter developed the Nutter strip float valve...

AI Technical Summary

Problems solved by technology

[0004] However, a relatively big problem existing in the strip float valve tray and the strip float valve is that the valve plate can only be made of stainless steel, and the float valve is easy to get stuck, rusted or stuck during operation, and cannot be opened freely. When the plate is overhauled, the rusted float valve must be replaced, which seriously affects the efficiency of the tray. For this reason, the present invention designs a strip-shaped float valve tray to prevent the float valve from sticking.
