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.

升降貨梯http://www.jntr168.com/一旦油管破裂，造成升降貨梯下降速度過(guò)快時(shí)，防裂閥快速關(guān)閉，成節(jié)流狀態(tài)，使升降貨梯臺(tái)面緩慢下降，保障人身和設(shè)備的安全，從而起到了安全作用。防裂閥用于重載液壓升降平臺(tái)的安全防裂閥，由閥體、壓簧、滑閥和擋圈組成，閥體的腔體內(nèi)設(shè)有壓簧，壓簧與一可在腔體內(nèi)滑動(dòng)的滑閥連接，滑閥由嵌在閥體內(nèi)的擋圈限位，滑閥的頂部設(shè)有通孔，滑閥的底部為堵頭，腔體與閥體的進(jìn)、出口連通。緊靠油缸的近油口（也做出油口）處裝有防裂閥，當(dāng)液壓管路發(fā)生破裂時(shí)，堵頭封住閥體的進(jìn)口，切斷了油缸的外泄油流，以防止油管突然破裂發(fā)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.
