Driving mechanism 120 is restored to original state, that is, after switching to reset state, hydraulic fluid is by pushing pump, tee tube 335, connecting Adapter tube 4 250, transition valve 130, connecting tube 1, coupling tube 127 are flow back into the transfer tube of driving mechanism 120.

More optimize, it is to change and prolong that electrician, which rotates delay handle 216 to make and change the delay time of time-delay mechanism 200, When valve 210 specific discharge and realize, if rotation displacement is excessive so that delay spool 214 through-hole with connection mouth a212/ connect Connection area between logical mouth b213 is zero, i.e. the specific discharge of time-delay valve 210 is zero, then can make hydraulic fluid that can not pass through Time-delay valve 210, to make termination 300 that can not switch to closed state, high-tension circuit is fail to open, and is asked to solve this Topic, it is described to be set to the mounting hole wall that time-delay valve covers and be coaxially arranged in arc slot structure and be through to time-delay valve and cover end The restraint slot 218 in face, constraint protrusion 217 is provided with outside the delay valve rod 215 and constrains raised 217 free ends is located at about In beam slot 218, restraint slot 218 rotates forward the cell wall turned to along shaft 111 and is followed successively by constraint cell wall one, constraint cell wall two.

Electrician when rotation delay handle 216 and makes constraint protrusion 217 when changing the delay time of time-delay valve 210 in advance When free end and constraint cell wall two contact, the through-hole and connection mouth a212/ for the spool 214 that is delayed connect the connection face between mouth b213 Product is zero, i.e. the specific discharge of time-delay valve 210 is zero；Electrician rotates backward delay handle 216 and makes to constrain raised 217 free ends When contacting with constraint cell wall one, the through-hole for the spool 214 that is delayed and the connection area connected between mouth a212/ connection mouth b213 are most Big value, the i.e. specific discharge of time-delay valve 210 are maximum value；It is contacted by constraining raised 217 free ends with constraint cell wall one/bis-, To make electrician know whether the specific discharge of time-delay valve 210 is maximum value/zero.

Preferably, it is provided with the delay time scale value close to delay handle 216 on the switch housing end cap, and prolongs When handle 216 on be provided with the pointer to match with delay time scale value；Electrician can be according to pointer in delay time scale value On position read latch valve 210 delay time value.

In actual work, the opening process of this delay switch:

Electrician's rotation manual closing device 100, specifically: electrician rotates forward shaft 111 by close handles 112, and shaft 111 is just Turn and passing through transmission mechanism 140 makes transition valve 130 switch to transition state, transmission mechanism 140 switches to closed state, simultaneously at this time And interlock raised 114 free ends and contacted with the gearing cell wall two of linked slot, hereafter, shaft 111 rotates forward and traction drive block 113 is same Step rotates forward, and driving mechanism 120 is finally made to switch to driving condition；

Then driving mechanism 120 drives in hydraulic fluid to termination 300 and it is made to switch to closed state, specifically:

After driving mechanism 120 switches to driving condition, hydraulic fluid by coupling tube 127, connecting tube 1, transition valve 130, Connecting tube 2 230, time-delay valve 210, connecting tube 3 240, tee tube 335 flow into the push pump of delivery device 330, push pump Push piston rod 333, the promotion movement of trigger board 323 of pushing block 334 are run and passed through, termination 300 is switched to and closes Conjunction state, while during this, since hydraulic fluid needs certain time by time-delay valve 210, to realize termination 300 Switch to the purpose that the time of closed state delays；

The closing process of this delay switch:

Electrician inverts shaft 111 by close handles 112, and shaft 111 inverts and makes transition valve 130 by transmission mechanism 140 Backhaul state is switched to, transmission mechanism 140 switches to closed state and interlocks raised 114 free ends and linked slot at this time It interlocks cell wall one to contact, hereafter, the reversion of shaft 111 and the reversion of traction drive block 113, and restores driving mechanism 120 extremely Original state, that is, switch to reset state, at the same hydraulic fluid by push pump, tee tube 335, connecting tube 4 250, transition valve 130, Connecting tube 1, coupling tube 127 are flow back into the transfer tube of driving mechanism 120, and termination 300 switches to disconnection shape State, so far, this delay switch are restored to non-open state.
