Description
Technical field
The utility model belongs to reversal valve maintenance field, and in particular to a kind of pilot operated spool valve air operated reversing valve disassembly work
Tool.
Background technique
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 control condition and in case of emergency carry out enforceable safe control of valve position.
Air operated reversing valve can be classified as side valve type and two kinds of 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 mainly includes electromagnetism elder generation
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 slide valve of the guide's air pressure promotion main valve exported by electromagnetic priority valve
Movement, to control the switching of compressed air or change the flow direction of compressed air.When solenoid valve power loss, compressed air
It is switched to electromagnetic priority valve, while being flowed to the upper chamber of slide valve, and act on slide valve top.In the effect of compressed air
Under, slide valve top seal pad is contacted with valve seat, closes compressed air, is also turned on starting air and starting air exhaust.Work as electricity
When magnet valve obtains electric, mobile armature movement overcomes initial tension of spring, and electromagnetic priority valve is opened, and slide valve upper chamber and electromagnetic priority valve are arranged
Gas is connected, and slide valve rises under the action of compressed air, and slide valve lower seal pad is contacted with valve seat, connects compressed air and starting
Air simultaneously closes off starting 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, long service life
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 fastly
Speed, which efficiently repairs air operated reversing valve, seems especially 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: unclamping the connection bolt of electromagnetic priority valve and main valve, separates electromagnetic priority valve and main valve, use card
In pin hole above spring pincers or screwdriver insertion screw rod, slide valve is fixed, its rotation is prevented, unclamps lock using ratchet spanner and sleeve
Tight nut removes seal gasket press cover and gasket from starting air vents, takes out screw rod, spool, close from slide valve upper chamber
The components such as packing, piston successively remove spool, gasket, piston from screw rod, 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 the fixed difficulties of slide valve, pin hole easy damaged, and then lead
Cause frequent repetitive operation, repair time growth, working efficiency reduction, damage of components, equipment dependability and accuracy decline etc.
Disadvantage.
