Description
Technical field
The invention belongs to reversal valves to overhaul field, and in particular to a kind of pilot operated spool valve air operated reversing valve extracting tool.
Background technology
Air operated reversing valve be it is a kind of to change gas in pipelines flow direction control element, be used in industrial control system in
Adjust direction, flow, speed and the other parameters of medium.Pilot valve is all configured for the air operated reversing valve of important process control to make
For operation and control condition and in case of emergency carry out enforceable safe control of valve position.
Air operated reversing valve can be classified as two kinds of side valve type and rotary valve according to spool shape, but side valve type air operated reversing valve exists
It is extensive more than the application of rotary valve air operated reversing valve in the control system of compressed air.
Fig. 3 is a kind of structure diagram of closed type pilot operated spool valve air operated reversing valve, which includes mainly that electromagnetism is first
Two parts of pilot valve and main valve, wherein slide valve gear is in main valve.The reversal valve is applied in compressed air circuit, passes through electricity
The valve position of pivot losses or gains electric control electromagnetic priority valve, and then the guiding valve of the guide's air pressure promotion main valve exported by electromagnetic priority valve
Action, to control the switching of compressed air or change the flow direction of compressed air.When solenoid valve dead electricity, compressed air
It is switched to electromagnetic priority valve, while being flowed to the upper chamber of guiding valve, and acts on guiding valve top.In the effect of compressed air
Under, guiding valve top seal pad is contacted with valve seat, closes compressed air, is also turned on and is started air and startup air exhaust.Work as electricity
When magnet valve obtains electric, mobile armature movement overcomes initial tension of spring, electromagnetic priority valve to open, and guiding valve upper chamber arranges with electromagnetic priority valve
Gas is connected, and guiding valve rises under the action of compressed air, and guiding valve lower seal pad is contacted with valve seat, connects compressed air and startup
Air simultaneously closes off startup air exhaust.When armature or pilot valve break down, which can be with
Emergency manual control is carried out by manual knob.
Air operated reversing valve is because of spies such as its resistance is small, fast response time, load capacity is big, performance reliability is high, service life length
Point is widely used in the control system of compressed air.But meanwhile air operated reversing valve number of faults is also synchronous increases, how soon
Speed, which efficiently repairs air operated reversing valve, seems particularly urgent and important.
The pilot operated spool valve air operated reversing valve of same type there is no offer dismantling device in the prior art, usually using such as lower section
Formula overhauls reversal valve:The connection bolt of electromagnetic priority valve and main valve is unclamped, electromagnetic priority valve and main valve is detached, uses card
Spring clamps or screwdriver is inserted into the pin hole above screw rod, fixes guiding valve, prevents its rotation, unclamps lock using ratchet spanner and sleeve
Tight nut removes seal gasket press cover and gasket from starting in air vents, screw rod, spool, close is taken out from guiding valve upper chamber
The components such as packing, piston remove spool, gasket, piston from screw rod successively, clean each component of reversal valve, check and repair respectively
Component has the defects of no marking, if that can not repair, needs to be replaced, and sealing element and sealing ring is replaced, according to opposite with dismantling
Sequence is completed returning for reversal valve and is filled.
The problems such as though this method can complete the maintenance of reversal valve, and there are guiding valve fixation difficulty, pin hole easy damageds, and then lead
Cause frequent repetitive operation, repair time growth, working efficiency reduction, damage of components, equipment dependability and accuracy decline etc.
Disadvantage.

1, the extracting tool small volume, simple in structure, operation are easy, and are safeguarded simple;
2, reversal valve self structure is made full use of in extracting tool design, carry out dismounting using the tool changes without changing
To valve self structure;
3, the mounting plate of the extracting tool is made of visualization high intensity organic glass, it can be achieved that tool was installed
Journey visualizes, and then quick positioning when energy implementation tool installation;
4, reversal valve high safety and reliability is overhauled using the dismantling device, can effectively fixes guiding valve, while can effectively avoid
Clamp pin hole damages the risk and consequence of equipment;
5, the dismounting work efficiency of reversal valve can be effectively improved using the dismantling device, while can guarantee the matter of reversal valve maintenance
Amount.
