Abstract

The invention relates to the field of chemical equipment, in particular to a pressure blocking device which comprises a six-way valve, a first operation assembly, a second operation assembly and a control unit. The six-way valve comprises a first port, a second port, a third port, a fourth port, a fifth port and a sixth port; the first operation assembly comprises a first chamber, a first piston and a first drive mechanism; the second operation assembly comprises a second chamber, a second piston and a second drive mechanism; and the control unit controls the six-way valve to switch between afirst state and a second state according to detection results of a first limiting sensor and a second limiting sensor, and controls the first drive mechanism and the second drive mechanism to drive. According to the pressure blocking device, media can be transferred from low pressure to high pressure, and the operation continuity of a connecting device is ensured.

Description

technical field [0001] The invention relates to the field of chemical equipment, in particular to a pressure barrier device. Background technique [0002] Chemical plants are often composed of different unit equipment, and solid, liquid or gas media need to be transferred between each equipment, and the equipment may work under different pressures in different independent processes. When connecting the media pipelines of these devices, it is necessary to consider connecting the media under different pressure conditions together. On the premise of ensuring that the pressure at both ends will not interfere with each other, it is also necessary to maintain the transmission of the media, and it is necessary to design a special pressure isolation device. As a bridge connecting the middle. [0003] Especially with the enhancement of people's awareness of environmental protection, chemical plants, especially scattered small chemical plants, need to treat the waste gas and waste li...
