Beschreibung
Zusammenfassung:	The invention provides an oil and gas suspension type locking valve. The oil and gas suspension type locking valve comprises a pressurizing slide valve assembly and a locking slide valve assembly, wherein the pressurizing slide valve assembly and the locking slide valve assembly are sequentially assembled on a connecting body between an oil and gas suspension power cylinder and an energy accumulator; the pressurizing slide valve assembly is positioned between the locking slide valve assembly and a locking control system; the areas of the two end surfaces of the pressurizing slide valve assembly are different, and particularly, the cross section area of one side in contact with the locking slide valve assembly is smaller. Compared with the traditional locking device, the oil and gas suspension type locking valve has the advantage that the typical self-pressurizing effect is realized. 本发明提供种油气悬挂的闭锁阀，包括增压滑阀总成和闭锁滑阀总成，两个滑阀总成顺序装配在油气悬挂动力缸和蓄能器之间的连接体上，其中增压滑阀总成位于闭锁滑阀总成和闭锁控制系统之间，且增压滑阀总成的两个端面存在面积差，特别与闭锁滑阀总成接触的侧横截面积较小，与传统
