Abstract

The invention discloses a valve which relates to the technical field of mechanical equipment and aims to solve the problem in the prior art that a valve cannot allow passing of a straight-line detection device and cannot satisfy use demands under highly vacuum conditions. The valve disclosed by the invention comprises a valve base, a bellows, a drive mechanism, a control mechanism and a valve cover, wherein the bellows is firmly connected to the top end of the valve base; the bellows is sleeved by the valve cover; the control mechanism is installed in an inner cavity formed by the bellows and the valve base; and the drive mechanism matched with the control mechanism is installed on the control mechanism. The valve disclosed by the invention has the advantages that the use demands in a highly vacuum environment can be satisfied, and the straight-line detection device can be allowed to pass a straight-line channel of the valve so as to enter a sealed reactor, so that online or original-position internal observation detection of a poisonous and harmful research object with high chemical activity can be realized; and during replacement or detachment of the straight-line detection device, the valve is closed, so that fluids can be effectively stopped, and a high vacuum degree can be kept in the sealed reactor all the time.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a valve. Background technique [0002] Valves are the control components in the fluid delivery system, and they can play a key role in fluid operation, performing functions such as cut-off, regulation, flow diversion, reverse flow prevention, pressure stabilization, flow diversion, or overflow and pressure relief. According to the different operating objects and the specific requirements of the operating environment, the valves are also in various forms. The valves used in the vacuum system need to have a good ability to maintain the vacuum in the system. [0003] In scientific research or industrial production, the operation and storage of highly chemically active substances are often involved. Such operations need to create and maintain a high vacuum environment in a high-vacuum airtight device to ensure the chemical stability of highly active substances. In order...
