Safe drain mechanism of supercritical high pressure vessel

一种超临界高压容器安全排放机构

Abstract

The utility model discloses a safe drain mechanism of a supercritical high pressure vessel, which comprises a safe drain valve (1), an opening/closing air cylinder (2) and a connecting bottom plate (3), wherein the connecting bottom plate (3) is fixed on an operating platform (4) beside the safe drain valve (1) on a supercritical high pressure vessel (7), the opening/closing air cylinder (2) and a guiding chute seat (5) are mounted on the opening/closing air cylinder (2), an inclined plane sliding block (6) connected with the piston rod of the opening/closing air cylinder (2) is mounted in the chute of the guiding chute seat (5), and the inclined plane of the inclined plane sliding block (6) is in contact with the valve opening/closing control rod of the safe drain valve (1). By adopting the safe drain mechanism of supercritical high pressure vessel, the danger brought by manual operation of the safe drain valve can be avoided, and the harm on a human body caused by the media drained by the safe drain valve during the draining process can be effectively avoided. The safe drain mechanism of the supercritical high pressure vessel is safe and convenient to operate, simple in structure, low in manufacturing and running cost, and reliable in working.
本实用新型公开了一种超临界高压容器安全排放机构,包括安全排放阀(1)、开闭气缸(2)和连接底板(3),连接底板(3)固定在超临界高压容器(7)上的安全排放阀(1)旁的操作平台(4)上,在连接底板(2)上安装有开闭气缸(2)和导向滑槽座(5),在导向滑槽座(5)的滑槽中装有与开闭气缸(2)的活塞杆连接的斜面滑块(6),并且斜面滑块(6)的斜面能与安全排放阀(1)的阀门开闭控制杆接触。采用本实用新型能有效避免因人工手动操作安全排放阀所带来的危险,并能有效避免安全排放阀在排放时其所排放的介质对人体可能造成的伤害。本实用新型不仅具有操作安全方便的优点,而且还具有结构简单、制作和运行成本较低、工作可靠的优点。
