Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples.
Referring to Fig. 1, this electromagnetic cartridge valve includes the portions such as electromagnet 1, valve body 7, spool 6, spring base 2, gasket 5, spring 4
Part is successively arranged electromagnet, spring base, spring, gasket, valve body in the end of the spool from left to right.It is characterized in that: spool with
Valve body cooperation, and moved back and forth in valve body, spring base is connect by screw thread with spool left end, and spring left end is supported with spring base
It leans on, spring right end is resisted against valve body left end by gasket；Electromagnet is connect by screw thread with valve body, and electromagnet mandril is resisted against bullet
Spring abutment left end；Electromagnet and valve body are equipped with sealing ring.
Specific structure is as follows:
Wherein electromagnet 1 is equipped with connector sleeve 11 in the one end connecting with valve body 7, and the outside of connector sleeve 11 is equipped with screw thread, for making
Used time installation is equipped with sealing ring 3 in the bottom of thread.It also is provided with screw thread in the inside of connector sleeve 11, passes through screw thread and valve body 7
It is attached.The oral area of connector sleeve 11 is equipped with the conical surface, is sealed by the conical surface and valve body.
After valve body 7 is threadedly coupled with electromagnet 1, the mandril of electromagnet just passes through spring base 2 and acts on spool 6, spool 6
It can be moved back and forth inside valve body 7.Spring 4 is equipped on the left of spool 6, the spring base 2 is to be threadedly attached in 6 left side of spool
Side, and spring 4 is pressed on gasket 5, gasket 5 and 6 left side omoplate of spool are against while also with 7 end face of valve body against guaranteeing
The initial relative distance in spool each omoplate face and valve body hydraulic fluid port.
The valve body 7 of this electromagnetic cartridge valve is equipped with multiple hydraulic fluid ports, in the present embodiment, there is pressure oil port P, actuator port A, work
Make hydraulic fluid port B, drain tap T.Wherein, the rectangle that actuator port A, B shape reduce step by step, to adapt to the different flow of oil inlet and draining
It is required that being equipped with sealing ring 8 between each hydraulic fluid port.
It is equipped with through-hole in the middle part of the spool of this electromagnetic cartridge valve, connects spring cavity with T mouthfuls, prevents from forming dead space, reduces fortune
Dynamic damping.
This electromagnetic cartridge valve is under the electromagnetic force of electromagnet 1 and the collective effect of the elastic force of spring 4, thus it is possible to vary spool 6
The position of opposite valve body 7, that is, change the displacement of relatively each hydraulic fluid port of spool omoplate, to control the opening and closing of each hydraulic fluid port, work
It is as follows to make process:
1. when the electromagnet is powered off, spool position is as shown in Figure 1, two hydraulic fluid ports of A, B are all connected with T hydraulic fluid port at this time；
2. increasing electromagnetic force to a certain extent, spool is moved to position as shown in Figure 2, and A hydraulic fluid port and T hydraulic fluid port are connected at this time, B hydraulic fluid port
Start to connect with P hydraulic fluid port；
3. continuing growing electromagnetic force, spool is moved to position as shown in Figure 3, at this time A hydraulic fluid port start with P hydraulic fluid port connect, B hydraulic fluid port with
P hydraulic fluid port is connected；
4. when electromagnetic force maximum, spool position is as shown in figure 4, A, B hydraulic fluid port are all connected with P hydraulic fluid port, and opening is maximum at this time.
