Description

Output check valve of float glass annealing kiln side fan

Technical Field

The utility model relates to the technical field of check valves, in particular to an output check valve of a fan at the edge of a float glass annealing kiln.

Background

Through searching, although the low-pressure loss check valve for the blower provided by the patent with the publication number of CN213808099U can ensure that the check valve for the blower is reliably opened under smaller air pressure, the problem of resistance loss of the check valve for the blower is solved, the check valve for the blower has small resistance to gas flowing in the working process, the energy-saving effect is obvious for the check valve for the blower which continuously works for a long time, the valve body is of an open structure, can be conveniently opened, is convenient to assemble and maintain, has important significance in the aspects of improving the reliability of equipment, particularly saving the energy consumption of a system, and solves the problem that the valve plate always has heavier weight because the valve plate has enough strength. The common one-way valve is opened by pushing the valve plate by gas, but when the gas pressure is small, the valve is often not opened, and when the current one-way valve is in an opened state, the position of the valve plate is supported and maintained by flowing gas. Thus, the valve plate always applies a certain resistance to the flowing gas. Because the valve plate is relatively heavy, this resistance is not negligible. However, there is a resistance, there is an energy loss, and the energy loss due to the resistance which is continued for years and months is very remarkable, but there are also the following drawbacks:

1. when the conventional one-way valve is used, the one-way valve is started completely through ventilation, and the valve plate cannot be controlled to be opened automatically, so that the one-way valve cannot be opened when the gas flow is small.

In order to solve the problems, the utility model provides an output one-way valve of a fan at the edge of a float glass annealing furnace.
