Problems solved by technology

The traps currently used lack the filtering function and are easy to block. In order to prevent impurities in the water from clogging the trap, additional filtering equipment is required; at the same time, in order to prevent the condensed water from pouring back, the outlet of the trap usually needs to be equipped with a check valve, which makes the drainage system complicated. Inconvenient maintenance

Abstract

The invention relates to a water drainage device, in particular to a perforated-plate type water drainage device, and provides a perforated-plate type water drainage device of a pressure equalizing system. A runner is located in a shell. A filtering device is installed on a runner branch and comprises a filtering screen and a filter cover, the filtering screen is embedded in the inner wall of the shell, and the filtering screen is pressed and sealed through the filter cover. An adjustment device is connected with the shell in a threaded mode, and a sealing pad is arranged in the connecting position. An adjustment rod capable of moving vertically is vertically installed in an adjustable perforated plate, and a positioning ring is arranged on the adjustment rod. A return stopping device is arranged at the rear end of the adjustment device, a sealing seat is connected with the shell in a threaded mode, and the plane of a disc is perpendicular to the direction of fluid in the runner. The disc is fixedly connected with a movable guide rod, the guide rod is sleeved with an elastic part, and a support is connected with the shell in a threaded mode. The perforated-plate type water drainage device of the pressure equalizing system integrates the functions of filtering, water drainage and return stopping, can realize continuous water drainage without gas leakage, and has high practicability.

Description

technical field [0001] The invention relates to a hydrophobic device, in particular to an orifice-type hydrophobic device. Background technique [0002] The hydrophobic device is suitable for the drainage of steam condensed water, and is widely used in energy, petroleum, chemical, and metallurgical industries. The traps currently used lack the filtering function and are easy to block. In order to prevent impurities in the water from clogging the trap, additional filtering equipment is required; at the same time, in order to prevent the condensed water from pouring back, the outlet of the trap usually needs to be equipped with a check valve, which makes the drainage system complicated. Inconvenient maintenance. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides an orifice-type water-repellent device of the pressure equalization system, which integrates filtration, water-repellent and non-return functions, has a si...
