Rotation.When the rotation of valve rod 6 declines, the shaft shoulder 36 on valve rod 6 drives water discharging valve 18 and the entirety of feed-water valve 23 to move down, water-supply valve
Door 23 closes water inlet 9 after reaching lower limits, delivery port 10 and the insertion of water return outlet 12, and now valve rod 6 continues to decline, by holding
Continuous compression spring 8 increases the seal pressure of feed-water valve 23 until valve rod 6 stops the rotation.
As shown in Figure 6.When fastening valve, valve rod torque T need to overcome the pressure F of upper hose reclaimed water,
According to force equation, have
F=PS
In formula, the pressure of P-water；
S-feed-water valve lower end lifting surface area.
It is reported that, the hydraulic pressure P of passenger train water-feeding pipeline is 0.2MPa, and the valve pad diameter D=60mm that feeds water, soParameter is substituted into, is obtained：
F=0.2 × 2826=565.2N
The formula that axial load is changed with moment of torsion：
In formula：Ta- overcome moment of torsion needed for axial load；
F-axial load；
L-screw rod helical pitch；
The forward efficiency of η-feed screw.
Known screw rod helical pitch l=6mm, according to parameters such as screw flight lift angle, equivalent friction angles, calculates η=0.46, will
They substitute into above formula, obtain
Consult related data and understand that electric operator output torque need to take valve torque T with reference to safety value Ta1.5
Times, therefore T=1.5Ta=1.755Nm.Because valve also has manual operation function, so it is also contemplated that manually when torque.
It is reported that, adult operates the valve torque general in 25Nm or so, so electric operator output torque T'＞ 25Nm.
As shown in fig. 7, it also includes by disconnecting switch F11, switching switch SQ1, remote controller receiver U, drives button manually
S11, button S12, ETAD expected time of arrival and departure relay S2 are closed manually, time relay S3, manual open relay K1 is closed, is closed relay manually
Relay K4, the electrical apparatus control system of point control relay K11 compositions are closed in K2, remote control open relay K3, remote control,
Electrical apparatus control system operation principle：
Start to close disconnecting switch F11 during operation, system obtains electric.
Remote control operating mode：Switching switch SQ1 is pushed into auto station, remote controller receiver U obtains electric.When valve is opened, pass through
The remote control open relay K3 of remote control 35 is closed, and ETAD expected time of arrival and departure relay S2 obtains electric start-up operation, while manual open relay K1 obtains electric
Closure, motor 7 is rotated forward；After certain hour, ETAD expected time of arrival and departure relay S2 normally-closed contacts disconnect, and manual open relay K1 dead electricity disconnects,
Motor 7 shuts down.During valve closing, relay K4 is closed by the remote control of remote control 35 and is closed, closing time relay S3 must establish by cable
Beginning work, while closing relay K2 manually obtains electric closure, motor 7 is inverted；After certain hour, time relay S3 normally-closed contacts are closed
Disconnect, relay K2 dead electricity is closed manually and is disconnected, motor 7 shuts down.
Point control operating mode：Switching switch SQ1 is pushed into manual station, point control relay K11 closures.When valve is opened, crawl
Button S11 is opened manually, ETAD expected time of arrival and departure relay S2 obtains electric start-up operation, while manual open relay K1 obtains electric closure, motor 7 is just
Turn；After certain hour, ETAD expected time of arrival and departure relay S2 normally-closed contacts disconnect, and manual open relay K1 dead electricity disconnects, and motor 7 stops fortune
Turn.During valve closing, crawl closes button S12 manually, closes time relay S3 and obtains electric start-up operation, while closing relay K2 manually
Electric closure is obtained, motor 7 is inverted；After certain hour, close time relay S3 normally-closed contacts and disconnect, relay K2 dead electricity is closed manually and is broken
Open, motor 7 shuts down.
System have also been devised the upper and lower spacing defencive function of valve, specifically in ETAD expected time of arrival and departure relay S2 and pass time relay
A normally opened contact is with the addition of on device S3, the contact closes when normally-closed contact disconnects.Upper limit defencive function is beaten for valve
After opening, ETAD expected time of arrival and departure relay S2 normally-closed contacts disconnect, normally opened contact closure, such ETAD expected time of arrival and departure relay S2 just all the time it is electric, often
Closed contact will disconnect always, manual open relay K1 be in power failure state, now staff again tap on remote control 35 or
Point control is opened button S11 control valves opening and is changing to invalid operation manually, plays position limitation protection effect.
Lower limit defencive function is after valve is opened, to close time relay S3 normally-closed contacts and disconnect, normally opened contact closure, this
Sample close time relay S3 just all the time it is electric, normally-closed contact will be disconnected always, and relay K2 is closed manually in power failure state, this
When staff again tap on remote control 35 or point control is closed button S12 control valves and opened and is changing to invalid operation manually, rise
To position limitation protection effect.
Terminate to disconnect F11, system dead electricity during operation.
