升降货梯http://www.jntr168.com/防裂阀用于升降货梯的安全防裂阀，由阀体、压簧、滑阀和挡圈组成，阀体的腔体内设有压簧，压簧与一可在腔体内滑动的滑阀连接，滑阀由嵌在阀体内的挡圈限位，滑阀的顶部设有通孔，滑阀的底部为堵头，腔体与阀体的进、出口连通。紧靠油缸的近油口（也做出油口）处装有防裂阀，当液压管路发生破裂时，堵头封住阀体的进口，切断了油缸的外泄油流，以防止油管突然破裂发生下降失控事故。
Cargo lifter crack safety valve for cargo lifter cracking valve from the valve body, spring, slide valve and retainer composed of the body of the cavity has a compression spring, compression spring and a slide in the cavity of the slide valve is connected, is embedded in the top of the spool valve body by a collar stop, the slide valve is provided with a through hole, the bottom of the spool as the plug, the cavity and the valve body inlet and outlet connected. Close to the fuel tank near the oil port (also made port) at the air-cracking valve, when hydraulic lines ruptured and import plug valve seal, cutting off the flow of oil leaking cylinder to prevent the tubing sudden drop uncontrolled rupture accident.

升降货梯http://www.jntr168.com/一旦油管破裂，造成升降货梯下降速度过快时，防裂阀快速关闭，成节流状态，使升降货梯台面缓慢下降，保障人身和设备的安全，从而起到了安全作用。防裂阀用于重载液压升降平台的安全防裂阀，由阀体、压簧、滑阀和挡圈组成，阀体的腔体内设有压簧，压簧与一可在腔体内滑动的滑阀连接，滑阀由嵌在阀体内的挡圈限位，滑阀的顶部设有通孔，滑阀的底部为堵头，腔体与阀体的进、出口连通。紧靠油缸的近油口（也做出油口）处装有防裂阀，当液压管路发生破裂时，堵头封住阀体的进口，切断了油缸的外泄油流，以防止油管突然破裂发生下降失控事故。
Once cargo lifter pipeline rupture, resulting in decreased when cargo lifter too fast, quick closing valves crack, a throttling state, the slow decline in cargo lift table to ensure the safety of persons and equipment, which play a security role. Crack crack valve for safety valve hydraulic lifting platform overloaded by the body, spring, slide valve and retainer composed of the body of the cavity has a compression spring, compression spring and a slide in the cavity slide valve connection, fitted at the top of the spool valve body by a collar stop, the slide valve is provided with a through hole, the bottom of the spool as the plug, the cavity and the valve body inlet and outlet connected. Close to the fuel tank near the oil port (also made port) at the air-cracking valve, when hydraulic lines ruptured and import plug valve seal, cutting off the flow of oil leaking cylinder to prevent the tubing sudden drop uncontrolled rupture accident.
