[0016] like Figure 1-3 As shown, an oil circuit switch valve convenient for assembly comprises a valve sleeve 1 and a shell 2. One end of the shell 2 is provided with a mounting port 3, and the other end is provided with a contraction port 4 with a gradually decreasing diameter. A rear yoke 5, an armature 6, a front yoke 7, and a coil assembly 8 are installed in the shell 2. A plurality of locking blocks 9 for limiting the rear yoke 5, the armature 6, the front yoke 7, and the coil assembly 8 to the inside of the shell 2 are arranged around the mounting port 3. One end of the front yoke 7 is close to the contraction port 4 and is provided with a valve sleeve fixing groove 10. A fixing plate 11 is fixedly provided at one end of the valve sleeve 1. A T port 12, an A port 13, and a P port 14 are sequentially provided on the valve sleeve 1. A first channel 15, an active cavity 16, and a second channel 17 that are connected in sequence are provided inside the valve sleeve 1. The first channel 15 and the active cavity 16 are connected via a rear plugging port 18. The movable chamber 16 and the second channel 17 are connected through the front plugging port 19. A steel ball 20 is arranged in the movable chamber 16. The diameter of the steel ball 20 is larger than the diameter of the rear plugging port 18 and the diameter of the front plugging port 19. The P port 14 is connected to the second channel 17, the A port 13 is connected to the movable chamber 16, and the T port 12 is connected to the first channel 15. The fixed plate 11 is located in the valve sleeve fixing groove 10. The valve sleeve fixing groove 10 is surrounded by a plurality of limit blocks 21 formed by inward bending. The limit blocks 21 fix the fixed plate 11 in the valve sleeve fixing groove 10. The armature 6 is fixedly connected with a push rod 22. A through hole 23 is provided on the front yoke iron 7 for the push rod 22 to pass through. The push rod 22 passes through the through hole 23, the first channel 15 and the rear plugging port 18 in turn and then extends into the movable chamber 16 and supports the steel ball 20. The rear yoke 5, the armature 6, the front yoke 7, the coil assembly 8 and other components are fixedly assembled by the deformation of the lock block 9, and the valve sleeve 1 and the housing 2 are fixedly connected by the deformation of the limit block 21, so that the assembly of the entire oil circuit switch valve is simple and fast. When the coil assembly 8 is not energized, the oil flows into the second channel 17 from the P port 14, the oil has a certain pressure, and the steel ball 20 moves toward the rear plug 18. After the oil enters the active cavity 16, it flows out from the A port 13. After the coil assembly 8 is energized, the front yoke 7 generates magnetism, attracts the armature 6, and moves the armature 6 toward the front yoke 7, so that the push rod 22 pushes the steel ball 20 to move, and the steel ball 20 blocks the front plug 19. At this time, the oil at the A port 13 enters the active cavity 16 and the first channel 15 and flows out from the T port 12.
[0017] Furthermore, a steel ball seat 24 is fixedly installed in the first channel 15 , and an oil hole 25 is provided on the steel ball seat 24 . The oil hole 25 is connected to the first channel 15 , and the rear plugging port 18 is provided on the steel ball seat 24 and connected to the oil hole 25 .
[0018] Furthermore, an inner thread is provided on the inner wall of the first passage 15, and an outer thread matching the inner thread is provided on the steel ball seat 24. The steel ball seat 24 is easy to install, which reduces the difficulty of machining the interior of the valve sleeve 1.
[0019] Furthermore, an annular limiting platform 26 is provided in the first channel 15. The annular limiting platform 26 limits the position of the steel ball seat 24 to ensure the activity space of the steel ball 20.
[0020] Furthermore, the valve sleeve 1 is provided with a T ring groove 27, an A ring groove 28 and a P ring groove 29 in sequence, the number of the T ports 12 is two, the two T ports 12 are located at the bottom of the T ring groove 27 and on both sides of the valve sleeve 1, the number of the A ports 13 is two, the two A ports 13 are located at the bottom of the A ring groove 28 and on both sides of the valve sleeve 1, and the number of the P ports 14 is two, the two P ports 14 are located at the bottom of the P ring groove 29 and on both sides of the valve sleeve 1.
[0021] Furthermore, the locking block 9 is integrally formed with the housing 2, the limiting block 21 is integrally formed with the front yoke 7, and a plurality of mounting ears 31 with mounting holes 30 are fixedly connected to the housing 2. The mounting ears 31 facilitate the installation of the switch valve. After the housing 2 is produced, the rear yoke 5, the armature 6, the front yoke 7, and the coil assembly 8 are installed, and then the locking block 9 is pressed so that the locking block 9 is bent inward, and the rear yoke 5, the armature 6, the front yoke 7, and the coil assembly 8 are fixed in the housing 2. When installing the valve sleeve 1, the fixing plate 11 is inserted into the valve sleeve fixing groove 10, and then pressure is applied to the limiting block 21 so that the limiting block 21 is deformed inward, thereby fixing the fixing plate 11 in the valve sleeve fixing groove 10. This greatly improves the assembly efficiency of the entire oil circuit switch valve.
[0022] It is worth mentioning that the technical features such as the coil assembly 8 involved in the utility model patent application should be regarded as the prior art. The specific structure, working principle and possible control method and spatial arrangement method of these technical features can be selected by conventional methods in the field, and should not be regarded as the invention point of the utility model patent. The utility model patent will not be further elaborated.
[0023] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field through logical analysis, reasoning or limited experiments based on the concept of the utility model on the basis of the existing technology should be within the scope of protection determined by the claims.
