The device of the present invention works in the moving process, so if the second sealing ring 250 is directly sleeved on the filter element 210, displacement is easy to occur, so that the sealing effect is weakened, in this embodiment, the filter element 210 is provided with the annular groove 216, the annular groove 216 is matched with the second sealing ring 250 to form an open flow sealing position M, and the second sealing ring 250 has a certain elasticity due to the action of the annular groove 216, so that the filter element 210 can be tightly hooped, and displacement or dislocation cannot occur due to the movement of the filter element 210.
In addition, it should be noted that, in consideration of the installation of the fixing seat, on the other hand, when the flow sealing position M is opened, although the annular groove 216 can block the second sealing ring 250, the second sealing ring 250 contacts with the fixing seat 300 and the reaction force acts on the second sealing ring 250, the second sealing ring 250 still shifts or misplaces, so as to be illustrated in fig. 8, a threaded stop protruding block 260 is provided on the side of the annular groove 216 near the end cover 230, the stop protruding block 260 can be movably connected, three rotating holes 261 are provided on the side end surface of the stop protruding block 260, and the stop protruding block 260 can effectively avoid the second sealing ring 250 from shifting or misplacement.
Further, as shown in fig. 6 and 7, the filter element 210 is located at the open flow seal position M and the closed flow seal position N, respectively. When the device is installed, the liquid inlet pipe of the device can jack the filter element to the open flow sealing position M, after the liquid inlet pipe of the device is detached, the open end of the filter element loses the jacking force, and the closed end is impacted by high-pressure liquid, so that the filter element can move to the closed flow sealing position N.

For example, in the actual use process, the high-pressure liquid is water, and the number of holes of the filter screen 215 is 4-20 meshes; when the high-pressure liquid is oil (lubricating oil, hydraulic oil, etc.), the number of holes of the screen 215 is 20 to 100 mesh.
In fig. 5, the end surface of the closed end 212 is formed with a liquid pressure surface 217 along the center, and when the metal hose connected with the device falls off, the high-pressure liquid medium forms an impact force on the liquid pressure surface 217 of the filter element 210, so that the quick stop can be realized. In this embodiment, through hydrodynamic calculation, the liquid pressure surface 217 is a concave surface, and the concave surface may be a conical surface, an arc-shaped concave surface, or other structural surfaces with the same function, so that when the high-pressure liquid medium impacts the liquid pressure surface 217, the center of the closed end 212 of the filter element 210 is stressed, so that the liquid medium can be rapidly stopped.
The device of the present invention has the function of filtering, and after a period of use, the filter element needs to be cleaned, so that the end cover 230 is provided with external threads matched with internal threads of the filter element 210, and the end cover 230 can be opened, so that the filter element 210 can be cleaned conveniently.
The device is applied to a steel rolling production line of a certain steel mill, the joint is arranged between the high-pressure hydraulic oil pipe and the rolling mill, the working pressure of the high-pressure hydraulic oil pipe is 16MPa, when the joint is not used, the high-pressure hydraulic oil pipe falls off due to long-time use (vibration, aging and other reasons), hydraulic oil splashes on a steel plate to be rolled which is communicated in red, and the steel plate is instantaneously ignited and burned, so that the life safety of field operators is endangered, and meanwhile, precision rolling equipment is burnt. Through the application of the device, once the oil pipe falls off, the filter element 210 rapidly cuts off the pipeline under the action of high-pressure oil, so that the possibility of fire caused by falling off of the oil pipe is greatly reduced, and the device is safe and reliable to use.
The foregoing is only a preferred embodiment of the invention, it being noted that: it will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the principles of the present invention, and such modifications and adaptations are intended to be comprehended within the scope of the invention.
