A filter valve is a filtering device that must be equipped for using a hydraulic control valve and a precision mechanical product that is prone to clogging. An engine is a machine that can convert other forms of energy into mechanical energy. Engines are divided into piston engines, ramjet engines, rocket engines, and turbine engines. Its working process is intake, compression, fuel injection, combustion, expansion work, and exhaust.

[0003] For example, in Chinese Patent (CN207599081 U), it includes a filter valve body. Side walls are formed on both sides of the filter valve body. A mating surface is formed above the side walls. A mating hole is formed at the middle position of the mating surface. Screws are placed in the mating hole. The two side walls are connected between the mating surfaces through a bracket. A convex block is formed on one side of the bracket. A groove is formed on the convex block. A connecting wall is formed on the other side of the bracket. The connecting wall is respectively connected to one end of the two side walls. An extending convex block is provided on one side of the mating surface. The extending convex block and the convex block formed on the bracket are located on the same side. A positioning block facing upward is formed at the end of the extending convex block. A positioning block is arranged beside the screw on the filter valve. Due to the existence of the positioning block, the filter valve can be position-limited accordingly, and it can avoid the situation of winding after the lead wire or other components on the filter valve are installed as in the prior art because the filter valve can rotate arbitrarily, and it can also reduce the occurrence of potential safety hazards.

[0004] The above solution still has the following technical deficiencies. The above solution is not convenient for discharging the filtered impurities. After the filter screen filters the impurities in the oil and gas, it will cause the accumulation of impurities. And during the process of discharging the impurities, the filter valve needs to be disassembled, and the whole process is relatively cumbersome. Based on this, an engine oil and gas filter valve is proposed. Content of the Utility Model

[0022] The threaded cylinder 3 in this embodiment facilitates the installation of the slag discharging mechanism 400, and the cylinder 5 is used to facilitate the installation of the jitter mechanism 700. The slag discharging mechanism 400 is used to discharge the impurities filtered by the filter net 6, and the jitter mechanism 700 is used to shake off the impurities stuck on the filter net 6.

[0023] It should be noted that a circular hole is opened in the middle of the partition plate 2, and the circular hole is used to allow the oil and gas to pass through.

[0024] Please refer to Figure 1 and Figure 2, To facilitate the discharge of the filtered impurities, the slag discharge mechanism 400 in this embodiment includes an air inlet pipe 401 threadedly connected inside the threaded cylinder 3 and a sealing ring 409 fixed inside the right side wall of the valve body main body 1. A blanking pipe 402 is fixed to the bottom end of the air inlet pipe 401. A plurality of air inlets are provided on the air inlet pipe 401. External threads are provided on the outer surface of the air inlet pipe 401, and the external threads are matched with the threaded cylinder 3. A first flange plate 403 is fixed to the bottom side of the blanking pipe 402. A second flange plate 404 abuts against the bottom side of the first flange plate 403. A plurality of bolts 405 are movably connected inside the first flange plate 403. Nuts 406 are threadedly connected to the outer surfaces of the bolts 405. A slag discharge pipe 407 is fixed to the bottom side of the second flange plate 404. A pipe cap 408 is threadedly connected to the outer surface of the slag discharge pipe 407. An installation groove is provided on the right side of the valve body main body 1, and the sealing ring 409 is fixed inside the installation groove. The outer surface of the pipe cap 408 abuts against the inner wall of the sealing ring 409.

[0025] In the slag discharge mechanism 400 of this embodiment, the oil and gas can enter the threaded cylinder 3 through the air inlet pipe 401. The air inlets are used to facilitate the entry of the oil and gas into the air inlet pipe 401. The first flange plate 403 and the second flange plate 404 are used to facilitate the fixation of the blanking pipe 402 and the slag discharge pipe 407.

[0026] It should be noted that the slag discharge pipe 407 and the second flange plate 404 can move to the right when it is necessary to disassemble the blanking pipe 402, so as to facilitate the removal of the blanking pipe 402. The cooperation of the bolts 405 and the nuts 406 can fix the first flange plate 403 and the second flange plate 404.

[0027] Please refer to Figure 1 、 Figure 3 and Figure 4 , To facilitate the dropping of the impurities on the filter net 6, the shaking mechanism 700 in this embodiment includes two sliding grooves 701 opened inside the left and right side walls of the cylinder 5. Springs 702 abut against the top sides of the sliding grooves 701. Limit blocks 703 are slidably connected inside the sliding grooves 701. A shaking plate 704 is fixed to the opposite sides of the two limit blocks 703. A plurality of elastic blocks 705 are fixed to the bottom side of the shaking plate 704. A plurality of rectangular holes are opened inside the shaking plate 704. The bottom sides of the elastic blocks 705 can collide with the top side of the filter net 6.

[0028] In the shaking mechanism 700 of this embodiment, the oil and gas drive the shaking plate 704 to move upward. When the shaking plate 704 falls under the action of gravity, it will drive the elastic blocks 705 to impact the filter net 6, so as to shake the filter net 6 and shake off the stuck impurities on the filter net 6.

[0029] It should be noted that the rectangular holes are used to allow the oil and gas to pass through the vibrating plate 704. The spring 702 is used to prevent rigid collision between the vibrating plate 704 and the cylinder 5. The limiting block 703 can limit the vibrating plate 704 by sliding in the limiting groove.

[0030] The working principle of the above embodiment is as follows:

[0031] The oil and gas enter the intake pipe 401 through the air inlet. Then, when the oil and gas pass through the filter net 6, the impurities carried by it are filtered out by the filter net 6. The filtered impurities fall into the slag discharge pipe 407 through the blanking pipe 402. Then, the oil and gas drive the vibrating plate 704 and the elastic block 705 to move upward. During the upward movement of the vibrating plate 704, the spring 702 is compressed. The spring 702 deforms to generate elastic force. Then, the vibrating plate 704 drops under the action of the elastic force and gravity of the spring 702. The vibrating plate 704 drives the elastic block 705 to move downward. The elastic block 705 collides with the filter net 6, so that the impurities stuck on the filter net 6 are shaken off. When it is necessary to discharge the impurities, unscrew the pipe cap 408, discharge the impurities from the slag discharge pipe 407, and then screw on the pipe cap 408 to seal the slag discharge pipe 407. When it is necessary to replace the intake pipe 401, remove the bolts 405 and nuts 406 from the first flange plate 403 and the second flange plate 404. Then, move the slag discharge pipe 407 to the right. The slag discharge pipe 407 moves within the sealing ring 409. When the slag discharge pipe 407 moves far enough to allow the intake pipe 401 to be taken out, rotate the intake pipe 401 and remove the intake pipe 401 and the blanking pipe 402 together for replacement.
