TWD184888S - Automatic drain valve - Google Patents

Abstract

[Use of article] This article is an automatic drain valve, for example, it is installed in a fluid pressure circuit that uses pressure fluid such as compressed air to drive an actuator, etc., and is used to remove various fluids from air dryers, air tanks, filters, etc. The drain fluid discharged from the pressure machine is temporarily stored, and is automatically discharged to the outside every time a roughly certain amount is accumulated. ; When using, first, connect the drain fluid discharge pipe to the drain fluid discharge port, and connect the drain fluid discharge port of a fluid pressure machine such as an air dryer to the drain fluid inlet. When the drain fluid is discharged from the fluid pressure machine, the drain fluid passes through the drain fluid introduction port and is accumulated inside the cover of the article. When the drain fluid reaches a predetermined amount, the drain fluid will be automatically discharged from the drain fluid discharge port due to the action of the drain fluid automatic discharge mechanism. ;[Design Description];The automatic drain valve consists of a main body and a cover fitted to the main body (refer to the reference perspective view 1 showing the names of each part and the reference perspective view 2 showing the names of each part). ; The upper surface of the main body is provided with: a drain fluid introduction port connected to the inside of the aforementioned cover, and a relief valve mounting hole for mounting a relief valve (not shown). ; A locking button is provided on the outer periphery of the cover, and a drain fluid outlet is provided at the lower end of the cover. An automatic drain fluid discharge mechanism (not shown) is housed inside the cover.
