Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
A pipeline explosion-proof valve comprises a rectangular valve body 8, wherein a flange 5 is arranged on the top surface of the rectangular valve body 8, three groups of safety valves 1 are arranged on the front side of the rectangular valve body 8, a mounting hole 4 is formed in one side surface of the rectangular valve body 8, and an actuating mechanism interface 3 and a plug head 2 are arranged on the other side surface of the rectangular valve body 8; the safety valve groups formed by the three groups of safety valves 1 are connected in parallel, oil inlets of the safety valves 1 are connected with an oil source through flanges 5, and the flanges 5 are connected with the oil source through rubber pipes; an oil outlet of the safety valve 1 is connected with an execution mechanism interface 3, and the execution mechanism interface 3 is connected with an oil cylinder or a motor through a sealing ring.
The safety valve 1 is a flow safety valve, which is used to keep the hydraulic actuator in position when the hydraulic line is broken, and the flow safety valve can allow oil to flow out of or into the actuator, but if the flow out of the actuator exceeds the set value of the safety valve set, the safety valve set can be closed quickly. (Note: because the valve bank responds quickly, the valve bank is sensitive to any transient flow beyond the set point.)
The safety valves 1 comprise valve ports 6 and load ports 7, three groups of safety valves 1 are connected in parallel, the valve ports 6 of each group of safety valves 1 are converged and connected with an oil source through flanges 5, and the load ports 7 of each group of safety valves 1 are converged and connected with an oil cylinder or a motor through an execution mechanism interface 3. When the flow rate of the load port 7 flowing to the valve port 6 is greater than the set value of the safety valve 1, the safety valve group is closed; the safety valve group can be reset again when the pressure of the load port 7 of the valve port 6 is equal. The flow fuse valve setting must be 25% greater than the system maximum flow (the customer must provide the set flow value at order)
Further, the safety valve 1 is made of an alloy steel valve seat, and parts inside the safety valve 1 are made of carbon steel.
Further, the relief valve 1 has a floating structure, and can reduce interference caused by an installation torque and a hole type machining error.
The utility model discloses a board-like mounting structure can be connected the valve port of relief valve directly with actuating mechanism, does not have middle pipeline, and when the pipeline bursts suddenly downstream, this valve can be in time closed, continues to keep the function of load, forms the function of a lock, and adopts three safety valves of group, can be applicable to large-traffic system, and the highest 300LPM that can reach.
