In conjunction with Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the remote actuator of a kind of fire-closing valve of the present invention, it comprises executive module and accessory assembly therefor.
It is ZL200620106001.5 in a patent No. of application in 2006 that described executive module is the inventor herein, and name is called: the product of remote exhaust smoke valve actuator.The remote actuator of this fire-closing valve of design this time is exactly on the basis of original remote exhaust smoke valve actuator, the improvement that its accessory assembly therefor that is used is carried out.So at this executive module is referred to do preliminary explanation, no longer is described in detail.With reference to shown in Figure 4, what be accessory assembly therefor that present embodiment will describe raises enclosing cover plan view afterwards.
Accessory assembly therefor in the remote actuator of described fire-closing valve of the present invention comprises base plate 1 and for driving valve blade main shaft 11 rocking arms 9 of rotation synchronously, rocking arm 9 intermediate portions and base plate 1 are rotatably assorted, and base plate 1 is provided with temperature controlling device.
Described temperature controlling device comprises fork 2, rope sheave 3, positioning plate 4, temperature sensor 6, bumping post 8, rocking arm 9, spring 10; Fork 2 one ends and base plate 1 are rotatably assorted, and an end of fork 2 the other ends and positioning plate 4 is hinged, and the other end of positioning plate 4 is provided with the U-shaped breach, and the two ends with fork 2 are defined as rotation end and rounded end respectively here.Temperature sensor 6 screws on base plate 1, and just base plate 1 is provided with a tapped hole, and the outside thread that temperature sensor 6 heads also match with tapped hole is so temperature sensor 6 can screw on base plate 1.
In conjunction with shown in Figure 1, the mandrel 6.1 card limits on temperature sensor 6 heads are in the U-shaped breach of positioning plate 4; Rope sheave 3 is rotatably assorted on fork 2 and the rounded end of close fork 2, the rotation end of fork 2 and rocking arm 9 one ends are being connected the two ends of spring 10 respectively; the other end of rocking arm 9 is walked around rope sheave 3 through wire rope 5 and linked to each other with actuator, and just wire rope 5 passes guide sleeve 7, walks around rope sheave 3; end is fixed on the rocking arm 9; the other end of wire rope 5 links to each other with remote actuator, because actuator is prior art, also are lifted in the middle of the background technique; repeat no more here, also do not draw among the figure.
Described fork 2 one ends and base plate 1 are rotatably assorted and refer to fix on the base plate 1 a fork axle 2.1, and fork 2 rotating sleeves are contained on the fork axle 2.1.
Described rope sheave 3 is rotatably assorted and is referring to fix a sheave shaft 3.1 near free end on the fork 2 on the fork 2 and near the rounded end of fork 2, and rope sheave 3 rotating sleeves are contained on the sheave shaft 3.1.
Be with the guide sleeve 7 that is fixed on the base plate 1 on the described wire rope 5.
The intermediate portion of rocking arm 9 is provided with the through hole 9.1 for proportioning valve gate flap sheet main shaft, radially is penetrated with at least one locking nut 9.2 on through hole 9.1 arms.Present embodiment has designed two locking nuts 9.2
On the described base plate 1 bumping post 8 is arranged fixedly, block between fork 2 and rocking arm 9.
Working principle of the present invention is: during use, accessory assembly therefor of the present invention is installed on the fire-protection valve, the blade main shaft 11 of fire-protection valve passes the through hole on the base plate 1 of accessory assembly therefor of the present invention, insert the through hole 9.1 on the rocking arm 9, fixedly connected by two locking nuts 9.2 on the rocking arm 9, adjust the position of rocking arm 9, by wire rope 5 pulling rocking arms 9, making rocking arm 9 rotate to the position of bumping post 8 is 90 ° through executive module.
When need are opened the fire-closing valve valve, in conjunction with Fig. 1 and shown in Figure 4, insert by spanner in the rotating shaft 12 of executive module, driving rope sheave dish 13 clockwise rotates, pulling wire rope 3.1, thereby drive rocking arm 9 and be rotated counterclockwise 90 °, blocked and to rotate by bumping post 8 to rocking arm 9, because the rope sheave Pan13Chu of executive module is located at ratchet 14, also be provided with the ratchet 15 that matches with ratchet 14 on the executive module, therefore, after rocking arm 9 is blocked by bumping post 8, decontrol the spanner on the executive module, rope sheave dish 13 rotation of also can not issuing licence.This moment, the spring 10 of rocking arm 9 the other ends was elongated, and formed certain pulling force, in conjunction with state shown in Figure 1.Because the other end of wire rope 5 is fixed in the executive module, spring 10 can't spur rocking arm 9 rotations, so rocking arm 9 temporarily is in state shown in Figure 1.When temperature reaches or surpasses the temperature that temperature sensor 6 sets (being generally 70 ℃), temperature sensor 6 inner fusing, in the head indentation temperature sensor 6 of temperature sensor 6 mandrels 6.1, the U-shaped breach that breaks away from positioning plate 4, positioning plate 4 loses drag effect, this moment, pulling force the right handed power that rocking arm 9 is applied of spring 10 just can the generation effect, and spring 10 pulling rocking arms 9, wire rope 5 and fork 2 turn clockwise together, in conjunction with state shown in Figure 3.Turning clockwise and then driving the blade main shaft 11 that is connected with this accessory assembly therefor of rocking arm 9 turns clockwise thereby drive fire-protection valve, makes valve closing, plays the frpf effect.
