In addition, 6.1 surface attachment of mandrel has lubricating oil, further reduce its rubbing between some thimbles 42
Wipe.
Do not contacted between the thimble 42, and each thimble 42 be engaged with the mandrel 6.1 one end end face it
Between gap it is identical so that 6.1 uniform stressed of the mandrel.
In addition, the executive module further includes and rocking arm 9, swing rod 2, rope sheave 3, positioning plate 4, bumping post 8, rocking arm 9, spring
10,9 middle part of rocking arm is rotatably assorted with bottom plate 1, and with the main shaft synchronous rotary.Described 2 one end of swing rod is rotated with bottom plate 1
Coordinate, the round end of the other end and positioning plate 4 is hinged, and the both ends of swing rod 2 are respectively defined as turning end and hinged end here.Temperature
Sensor 6 is screwed on bottom plate 1, that is, bottom plate 1 is equipped with a threaded hole, and 6 head of heat detector is also outer with corresponding threaded holes
Screw thread, so heat detector 6 can be screwed on bottom plate 1.
With reference to shown in Fig. 1, rope sheave 3 is rotatably assorted on swing rod 2 and close to the hinged end of swing rod 2, the turning end of swing rod 2 with
9 one end of rocking arm respectively connected the both ends of spring 10, and the other end wire-diameter steel rope 5 of rocking arm 9 bypasses rope sheave 3 and executing agency's phase
Even, that is, steel wire rope 5 pass through guide sleeve 7, and around rope sheave 3, one end is fixed on rocking arm 9, the other end of steel wire rope 5 and to steel
The second executing agency that cord 5 applies pulling force is connected, and since the second executing agency is the prior art, also lifts among background technology
Arrived, which is not described herein again, is also not drawn into figure.
Described 2 one end of swing rod is rotatably assorted with bottom plate 1 to be referred to fix a pendulum shaft 2.1 on bottom plate 1,2 turning set of swing rod
In pendulum shaft 2.1.
The rope sheave 3 is rotatably assorted on swing rod 2 and refers to close to the hinged end of swing rod 2 on swing rod 2 close to free end
A sheave shaft 3.1 is fixed at place, and 3 turning set of rope sheave is on sheave shaft 3.1.
The guide sleeve 7 being fixed on bottom plate 1 is cased with the steel wire rope 5.
The middle part of rocking arm 9 is equipped with the through hole 9.1 for being used for coordinating valve blade main shaft 11, is radially passed through on 9.1 arm of through hole
It is installed with least one lock screw 9.2.
Bumping post 8 is fixed with the bottom plate 1, is blocked between swing rod 2 and rocking arm 9.
The operation principle of the utility model is:In use, the accessory assembly therefor of the utility model is installed on fire-protection valve,
The blade main shaft 11 of fire-protection valve is through the through hole on the bottom plate 1 of the utility model accessory assembly therefor, the through hole being inserted on rocking arm 9
9.1, it is fixedly connected by two lock screws 9.2 on rocking arm 9, adjusts the position of rocking arm 9, pass through steel wire rope through executive module
5 pull rocking arm 9, and it is 90 ° rocking arm 9 is rotated to the position of bumping post 8.
Fig. 5 be the utility model long-distance actuating mechanism of fireproof valve structure in executive module raise the inside after cover board
Structure diagram.Incorporated by reference to shown in Fig. 1 and Fig. 5, when that need to be opened to fire resisting damper valve, executive module is inserted into by spanner
Shaft 12 in, drive rope sheave disk 13 to rotate clockwise, steel wire rope 3.1 pulled, so as to drive rocking arm 9 to be rotated by 90 ° counterclockwise, extremely
Rocking arm 9 is blocked by bumping post 8 to be rotated, and since the rope sheave Pan13Chu of executive module is arranged on ratchet 14, be additionally provided with executive module
The pawl 15 to match with ratchet 14, therefore, after rocking arm 9 is blocked by bumping post 8, decontrols the spanner on executive module, rope sheave disk
13 will not issue licence rotation.The spring 10 of 9 other end of rocking arm is elongated at this time, forms certain pulling force, the shape with reference to shown in Fig. 1
State.Since the other end of steel wire rope 5 is fixed in executive module, spring 10 can not pull rocking arm 9 to rotate, so rocking arm 9 is temporary transient
In state shown in Fig. 1.When the temperature that temperature is set up to or over heat detector 6 (generally 70 DEG C), inside heat detector 6
Fusing, the head of the mandrel 6.1 of heat detector 6 are retracted in heat detector 6, depart from the U-shaped breach of positioning plate 4, positioning plate 4 loses resistance
Effect, with regard to that can act, spring 10 is pulled and shaken the right handed power that the pulling force of spring 10 applies rocking arm 9 at this time
Arm 9, steel wire rope 5 and swing rod 2 rotate clockwise together, the state with reference to shown in Fig. 4.Rocking arm 9 rotating clockwise and then driving
The blade main shaft 11 being connected with this accessory assembly therefor, so as to drive fire-protection valve to rotate clockwise, closes valve, plays fireproof
Effect.
In the utility model, some thimbles 42 are set in the U-lag 41 of positioning plate 4, pass through thimble 42 and the mandrel
6.1 are in contact, and then the contact of existing face is changed to point contact, reduce the contact area between the mandrel 6.1, and then
Reduce friction so that the disengaging between mandrel 6.1 described in locating rod rain is more rapid, and then improves executive module reflection
Sensitivity.Meanwhile the thimble 42 is on the same sagittal plane of the mandrel 6.1, on the premise of being fixed to mandrel 6.1,
Reduce the friction between the mandrel 6.1.And lubricating oil is attached with mandrel 6.1, then further reduce its surface
Friction.
It these are only the utility model preferred embodiment, not thereby limit the embodiment and protection of the utility model
Scope, to those skilled in the art, should can appreciate that all with the utility model specification and diagramatic content institute
The equivalent substitution made and obviously change obtained scheme, should be included in the scope of protection of the utility model
It is interior.
