Abstract
The invention relates to the field of gate valve installation and maintenance, in particular to a rapid debugging method for ZB and ZC electric gate valves. The rapid debugging method includes the steps: 1 checking marking of the electric gate valves; 2 determining pitches of valve rods of the electric gate valves; 3 adjusting corresponding positions according to positions of the electric gate valves; 4 adjusting a gate valve travel control structure, determining whether the valves reach fully open positions or not according to the calibers of the valves and positions of the valve rods, adjusting a valve travel controller and ensuring effective action of micro-switches at 'fully open' positions; 5 closing the gate valves, opening the gate valves again and rechecking the travel of the c gate valves. By the aid of the steps, adjusting steps are simple, effective and safe, and the electric gate valves can be directly and rapidly debugged.
Description
Technical field
The present invention relates to gate valve installation and maintenance field, be specially a kind of ZB, ZC class electric gate valve method for rapidly debugging.
Background technique
Electric gate valve is by Electric actuator and gate valve entity is supporting forms, Electric actuator in order to control the opening and closing of gate valve, electric gate valve advantage be can execute-in-place also can remote-controlled operation.If it is improper that the Electric actuator of electric gate valve adjusts, gently then shorten gate valve working life; Heavy then cause valve cast iron housing to rupture, control motor and burn out and the serious accident such as water logging pump house.
The adjustment method of conventional electric gate valve comprises the inspection of gate valve mechanical device, Electric actuator channel check, torque-limiting mechanism debugging, Open valve debugging, journey controller debugging, step such as energising running in, the adjustment of valve position transmitter etc., the method repeatedly need be dismantled gate valve, be assembled, i.e. consuming time but also effort.
Summary of the invention
The object of the present invention is to provide a kind of quick, safe electric valve adjustment method.
In order to achieve the above object, the present invention is achieved in that
A kind of ZB, ZC class electric gate valve method for rapidly debugging, it comprises
Step 1, electric gate valve indicate and check;
Step 2, confirm adjust the valve rod tooth distance of electric gate valve;
Step 3, adjustment relevant position, gate valve present position according to electric gate valve; Step 3.1, gate valve then adjust " full cut-off " position in " full cut-off " position: make valve rod rotate half-turn or a circle to the rotation of " unlatching " position on gate valve by manual mode;
Step 3.2, connect gate valve power supply, open gate valve close/open valve and press, check that valve rod turns to whether consistent with turning to during hand rotation gate valve;
Step 4, adjustment gate valve stroke controlling structure;
Step 4.1, gate valve is adjusted to " full cut-off " position;
Step 4.2, gate valve is adjusted to " standard-sized sheet " position;
The rotation number of turns of valve rod when step 4.3, record gate valve are " standard-sized sheet " position from " full cut-off " position transition;
Step 4.4, according to valve aperture, valve rod tooth apart from determining whether valve reaches fully open position and adjust valve journey controller, guarantee that the sensitive switch action of " standard-sized sheet " position is effective;
Step 5, gate valve are closed and are reopened, check brake gate door stroke.
The present invention adopts above-mentioned steps, and its set-up procedure is simple, effective, safety, can directly debug electric gate valve fast.
Embodiment
The present invention is further illustrated below by way of specific embodiment.
An adjustment method for ZB, ZC class electric gate valve, comprising:
Step 1, electric gate valve indicate and check;
Step 2, confirm adjust the valve rod tooth distance of electric gate valve;
Step 3, serve power supply and press "ON" button.Check and turn to, if after pressing valve opening button, turning to of valve rod is consistent with turning to of valve rod during manual valve opening, illustrates that the phase sequence of motor is consistent with the direction of the electric controller of valve; If after pressing valve opening button, turning to turning to of valve rod during manual valve opening of valve rod is inconsistent, then stop power transmission immediately, the phase sequence of adjustment motor wiring after having a power failure, until inspection turns to consistent.
The range controlling mechanism of step 4, adjustment gate valve, is transferred to full close position by gate valve, and after full close position adjustment, adjustment gate valve is to fully open position.When opening gate valve, record gate valve rod rotates the number of turns, and as the electric gate valve of DN500, its valve rod tooth is apart from be 8mm, and valve rod turns around and opens 8mm, and standard-sized sheet time gating valve plate will move upward 500mm, so valve rod need rotate 500/8=62.5 and encloses during standard-sized sheet.Now press valve opening button to count to 63 circle valves and to have arrived " standard-sized sheet " position, the journey controller of regulating valve valve electric device, makes the sensitive switch action of " standard-sized sheet " position.
Step 5, closed by electric gate valve, then open inspection one time, adjustment terminates.
Wherein, if electric gate valve is before adjustment in enable possition, just first should adjust the position of unlatching, described in step is pressed above.
In addition, electric gate valve uses a period of time to regulate again, check that Cock screw in the adjusting nut of a torque-limiting mechanism whether loosens or comes off, prevent electric gate valve from use occurring to be split by top by the connection gusset that Electric actuator is fixed in valve plate bursting or top bottom gate valve.If the Cock screw of the adjusting nut in torque-limiting mechanism makes adjusting nut tighten up spring for a long time because loosening to drop out; until kill spring, make torque-limiting mechanism ineffective, be failure to actuate when crossing moment; do not cut off the electricity supply and do not shield, cause electric gate valve damage accident.Therefore to check that Cock screw whether comes off, if Cock screw loose or dislocation will tighten in time, find out falling-away cause and reinforce.
The present invention adopts above-mentioned adjustment method, can facilitate, safety, fast and effectively ZB, ZC class electric gate valve adjusts.
