The two sliding grooves 14 are slidably installed with a barrier plate 3, and a push-pull rod 6 is fixedly installed on the barrier plate 3. This is to prevent maintenance personnel from losing the liquid oil inside the hydraulic solenoid valve 1 when the screening separation structure 9 is replaced with the replacement of the screening separation structure 9, so as to reduce the outflow of liquid oil in the hydraulic solenoid valve 1 and cause unnecessary Waste of resources, and economic losses.

A screening separation structure 9 is placed at the bottom end of the oil collection bin 12, and one end of the screening separation structure 9 penetrates the cavity 13 and extends to the inside of the oil pressure solenoid valve 1. The top end of the oil pressure solenoid valve 1 is installed with a limited position Block 2, and the number of limit blocks 2 is two.

The top end of the shaped metal strip 93 is equipped with an upper connecting block 92. The bottom end of the front of the upper connecting block 92 is provided with an upper fixing hole 91. The bottom end of the oil collecting bin 12 is installed. There are fixed blocks 7, and the number of fixed blocks 7 is two. The fixing blocks 7 are all screwed with screws 8, and the screening holes on the side of the grid separation net 96 that the shaped metal strip 93 is connected to are larger than the impurities. , And the screening hole on the other side is smaller than the impurities to ensure that the impurities in the hydraulic solenoid valve 1 will be concentrated on the grid separation net 96. At the same time, two limit blocks 2 are installed inside the hydraulic solenoid valve 1 to ensure Afterwards, the position of the screening separation structure 9 placed inside will not be shifted in the screening separation structure 9 due to the use of the hydraulic solenoid valve 1, which affects the efficiency of the screening separation structure 9 and the oil collection bin 12 The fixing block 7 installed at the bottom of the sump is fixed with a screw 8 to fix the screening separation structure 9 to prevent the screening separation structure 9 placed in the bottom end of the oil collection bin 12 from falling, and the elevator maintenance personnel are changing the screening separation The structure 9 can also be used. The fixed screw 8 removes the screening separation structure 9 and performs a follow-up change of the screening separation structure 9 to extend the service life of the hydraulic solenoid valve 1.

Working principle: In order to extend the service life of the hydraulic solenoid valve 1 when installing the hydraulic solenoid valve 1, the elevator installer should first install two limit blocks 2 inside the hydraulic solenoid valve 1 to ensure that, and then place it The position of the screening separation structure 9 inside will not be shifted in the screening separation structure 9 due to the use of the hydraulic solenoid valve 1, which will affect the efficiency of the screening separation structure 9, and the hydraulic solenoid valve The oil collecting bin 12 installed at the bottom of 1 and used to collect the impurities that are blocked and precipitated by the screening separation structure 9, and the oil collecting bin 12 is far away from the working output position of the oil pressure solenoid valve 1, ensuring that the oil pressure solenoid valve When the valve 1 is working, the impurities deposited in the oil collecting bin 12 will not return to the oil pressure solenoid valve 1 due to the operation of the hydraulic solenoid valve 1, and the oil collecting bin 12 is opened on both sides of the oil collecting bin 12 to discharge oil. Port 5 and water inlet 11 to facilitate elevator maintenance personnel to clean the inside of the oil collection bin 12, and at the same time, a fixing block 7 installed at the bottom end of the oil collection bin 12 fixes the screening and separation structure 9 by screw 8 , To prevent the screening separation structure 9 placed from the bottom end of the oil collection bin 12 from falling, and the elevator maintenance personnel can also use the fixed screw 8 to remove the screening separation structure 9 and separate the screening when replacing the screening separation structure 9 The structure 9 undergoes a follow-up change to extend the service life of the hydraulic solenoid valve 1. At the same time, when the maintenance personnel replace the screening separation structure 9, in order to ensure that the liquid oil inside the hydraulic solenoid valve 1 will not follow the screening separation structure 9 Therefore, slide grooves 14 are installed on both sides of the cavity 13 opened at the bottom end of the hydraulic solenoid valve 1, and barrier plates 3 are installed on the slide groove 14 so that maintenance personnel can take out the screening and separation structure 9 to At a certain position, the push-pull rod 6 installed on the blocking plate 3 can be used to slide the push-pull rod 6 to the bottom end of the cavity 13 and block the cavity 13 to prevent the liquid oil in the hydraulic solenoid valve 1 from flowing out. This causes unnecessary waste of resources. At the same time, in order to ensure that the screening and separation structure 9 can effectively separate impurities in the hydraulic solenoid valve 1, the screening and separation structure 9 is installed diagonally and passes through the bottom fixing hole 94 and the top top fixing hole. 91, to fix the shaped metal strip 93 on the periphery of the grid separation net 96, and it should be because one side of the grid separation net 96 has a larger screening hole than impurities, and the other side has a larger screening hole than The small impurities ensure that the impurities in the hydraulic solenoid valve 1 will be concentrated on the grid separation network 96, and the grid separation network 96 installed diagonally will cause the concentrated impurities to settle down along the installation track and fall into the collection. Inside the oil tank 12.
