简介： I. Brief introduction of Z2S6 superposition type hydraulic control check valve :
是依靠控制流体压力，可以使单向阀反向流通的阀。 Hydraulic control check valve is a valve that can make the check valve flow in the reverse direction by controlling the pressure of the fluid. This valve occupies an important position in the hydraulic support equipment of coal mine machinery. The difference between the hydraulic check valve and the ordinary check valve is that there is an additional control oil circuit K. When the pressure oil is not connected to the control oil circuit, the hydraulic check valve works like a normal check valve It only flows from the oil inlet to the oil outlet. It cannot flow in the opposite direction. When the oil pressure of the control circuit is input, the piston rod moves to the right under the action of pressure oil, and the check valve is opened with the rod to open the oil inlet and outlet. If the oil outlet is larger than the oil inlet, the oil flow can be reversed.
Z2S6型叠加式液控单向阀 分类： Classification of Z2S6 superposition type hydraulic control check valve :
Hydraulic control check valve is one of the directional control valves. Specific classification:
Directional control valves are divided into two categories: check valves and directional valves according to their functions in the hydraulic system.
Check valve in hydraulic transmission has ordinary check valve and hydraulic control check valve.

Z2S6型叠加式液控单向阀结构图： Structure chart of Z2S6 superposition type hydraulic control check valve: 注意事项： Nine, Z2S6 superposition type hydraulic control check valve Note:
Field practice has proved that hydraulic control check valves are prone to problems during use and maintenance. The following are precautions.
(1) It must be ensured that the hydraulic control check valve has sufficient control pressure, and the control pressure loss is absolutely not allowed. Attention should be paid to whether the control pressure meets the requirements of reverse opening. If the control of the hydraulic control check valve leads to the autonomous system, the influence of the pressure change of the main system on the pressure of the control oil circuit must be analyzed to avoid the malfunction of the hydraulic control check valve.
(2) According to the position of the hydraulic control check valve in the hydraulic system or the resistance of the liquid flow (back pressure) after the oil outlet chamber is reversed, choose the structure (simple or double) of the hydraulic control check valve and drain the oil reasonably. Method (internal or external). For internal drain type check valve, when the reverse oil outlet pressure exceeds a certain value, the hydraulic control part will lose control. Therefore, the internal drain type check valve is generally used for the reverse oil outlet chamber without back Occasions with low pressure or back pressure; and the leak-out hydraulic control check valve can be used in the case of high back pressure in the reverse oil outlet chamber to reduce the minimum control pressure and save control power. If the system adopts the internal unloading type, the plunger cylinder will drop intermittently to generate vibration and noise.
