Oil-way switching apparatus 100 proposed by the present invention is provided with flow-guiding channel in valve body 12, and spool is located in valve body 12
Portion, and can be moved under the driving of driving part, on and off flow-guiding channel；Detection part is provided on valve body 12
24, detection part 24 can detect the specific location of spool, and control module 30 can judge whether it is in work according to the position of spool
Make position.When detection part 24 detects that spool is not in operating position, indicate that oil-way switching apparatus 100 breaks down,
Or driving part is insufficient to the driving trip of spool, control module 30 can control driving part further spool to be driven to transport at this time
It is dynamic, so that spool is in operating position (specifically, the first conduction position and the second conduction position are referred to as operating position), control
Molding block 30 can also prompt staff to overhaul and subsequent processing.
Oil-way switching apparatus 100 proposed by the present invention can be with by the mutual cooperation of detection part 24 and control module 30
The position of real-time detection spool to judge whether oil-way switching apparatus 100 breaks down, and occurs in oil-way switching apparatus 100
Respective handling is carried out when failure or prompt staff repairs processing.
As shown in Figures 3 to 5, another embodiment of the invention proposes a kind of oil-way switching apparatus 100, comprising: valve body
12, spool, driving part, detection part 24 and control module 30.Wherein, the first flow-guiding channel and second are provided in valve body 12
Flow-guiding channel, driving part is for driving valve core movement, to change conducting or the pass of the first flow-guiding channel and the second flow-guiding channel
Closed state；Detection part 24 is used to detect the position of spool, and control module 30 is controlled according to the testing result of detection part 24 and driven
Dynamic component work.
In this embodiment, when spool is located at the first conduction position, the first flow-guiding channel is in the conductive state, and second leads
Circulation road is in close state；When spool is located at the second conduction position, the second flow-guiding channel is in the conductive state, the first water conservancy diversion
Channel is in close state.In the use process of oil-way switching apparatus 100, detection part 24 detects whether spool is in first
Conduction position or the second conduction position.When detection part 24 detects that spool is in the first conduction position, the first water conservancy diversion is indicated
Channel is in the conductive state, and the second on state is in close state, it was demonstrated that oil-way switching apparatus 100 works normally；Work as detection
When component 24 detects that spool is in the second conduction position, indicate that the second flow-guiding channel is in the conductive state, the first flow-guiding channel
It is in close state, it was demonstrated that oil-way switching apparatus 100 works normally；When detection part 24 detects that spool had both been not at first and has led
Logical position when not also in the second conduction position, indicates that the first flow-guiding channel and the second on state are in the conductive state simultaneously,
It proves that oil-way switching apparatus 100 breaks down, there is the danger of the two liquid mixing, control module 30 prompts staff at this time
Carry out maintenance and subsequent processing.
