Pollution discharge drain valve

Abstract

The invention discloses a pollution discharge drain valve. The pollution discharge drain valve structurally comprises a valve body, a valve rod, a hand wheel, a valve rod nut, a supporting rod, a packing pressing plate, a first fixing part, a separation ring, a packing, a valve clack, connecting devices and a stabilizing device. The connecting devices are arranged at the lower parts of the left end and the right end of the valve body correspondingly to be stabilized on the valve body through first connecting plates, then a convex ring is embedded in a clamping groove to be stabilized through asecond fixing piece and a third fixing piece, so that the beneficial effect of effectively improving the installation convenience is achieved; and the stabilizing device is arranged at the front endof the valve body, is stabilized on the valve body through a connecting rod, then is clamped to an outside part through a first half ring and a second half ring, and is preliminarily stabilized through a fourth fixing piece, then a rotating part is rotated to pass through a pressing block to improve the stability, and thus the effect of greatly improving the overall stability after installation isachieved.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a sewage trap. Background technique [0002] Steam trap is a kind of valve, also known as steam trap and drain valve, which is to discharge the condensed water, air and carbon dioxide gas in the steam system as soon as possible, and at the same time automatically prevent the leakage of steam to the greatest extent. There are many types of steam traps, each of which is different. performance, at present, the pipes and the lower end of the boiler in the power plant are equipped with sewage traps to discharge the sediment, oxide layer and condensed water produced by the pipelines and boilers in operation. With the rapid development of science and technology, sewage discharge The steam trap has also been technically improved, but the existing technology is not convenient enough for installation, and the overall fixing effect after installation is insufficient.
