Quick-opening valve for steam explosion device

Abstract

The invention provides a quick-opening valve for a steam explosion device. The invention relates to a valve, in particular to a gate valve used for a steam explosion machine. The invention aims at providing a quick-opening valve for a steam explosion device, which is suitable for the steam explosion device, is simple in structure and can realize quick opening of the valve. The quick-opening valve for the steam explosion device comprises a seal disc (1) provided with a valve hole (11) in the middle part, at least two slide bars (2) which are parallel to each other, a valve body plate (3) capable of sliding along the slide bars, a valve body (31) and a valve seat plate (4), wherein a buffer device is arranged on the end surface, close to the valve body plate, of the valve seat plate; the other end surface of the valve seat plate is fixedly provided with an oil cylinder body (5); a piston rod (52) passes through a through hole (41) and is fixedly connected with the valve body plate; the oil cylinder body is internally provided with a pressure spring (53) and / or a tension spring (54); one end of the oil cylinder body is provided with a vent hole (57), and the other end of the oil cylinder body is provided with a first oil through hole (55) and a second oil through hole (56) which have different sizes; and the quick-opening valve also comprises two electromagnetic valves which are respectively communicated with the two oil through holes.

Description

technical field [0001] The invention relates to a valve, in particular to a gate valve used in a steam explosion machine. Background technique [0002] Steam explosion technology, also known as steam explosion technology, is also called steam explosion technology or steam flash explosion technology. It has broad application prospects in the field of crop straw utilization. The book "Principles and Applications of Steam Explosion Technology" edited by Chen Hongzhang and Liu Liying (publisher: Chemical Industry Press; ISBN: 9787502599515; publication time: 2007-04-01) elaborates on steam explosion technology in detail. Steam explosion technology mainly uses high temperature and high pressure steam to treat fiber raw materials, and realizes the component separation and structural change of raw materials through the instantaneous pressure relief process. In order to realize the steam explosion process, a steam explosion device is generally used. The applicant's previous applic...
