Abstract
The utility model provides a temperature control automatic telescoping mechanism for an air inlet. The temperature control automatic telescoping mechanism comprises an installing frame, a fixing support fixed on the installing frame, a guide sleeve provided with a memory alloy spring by means of encapsulating, a guide rod movably sleeved at one end of the guide sleeve, a compressed spring movably sleeved at the other end of the guide sleeve, a movable support sleeved on the guide sleeve, and a mounting foot fixed to valve blades. Limiting steps for limiting the route of the compressed spring are arranged on the guide sleeve; the fixing end of the compressed spring is fixedly arranged on the fixing support. One end of the guide rod props against the memory alloy spring, and the other end of the guide rod extends out of the guide sleeve and props against the installing frame. The mounting foot is movably arranged on the movable support. By using the temperature control automatic telescoping mechanism, a valve of the air inlet can be opened or closed based on the temperature in a ventilating pipeline, and the part can be used continuously.
Description
Technical field:
The utility model relates to and a kind ofly is installed in air port in the building ventilation system with the automatic extending means of temperature control.
Background technique:
In the tall building ventilation duct is installed all at present, ventilation duct all leaves ventilated port in the room He in the corridor, and the place, air port is equipped with valve, and the opening and closing of valve realize ventilation in the room and fire prevention.Generally be provided with temperature sensor in the actuator that controls air port place's valve opening at present and close; Temperature sensor action and the action of drive actuator in the temperature of appointment; But can't reuse again after this temperature sensor action, promptly need change after the action temperature sensor.
The model utility content:
The utility model provides a kind of can open or close the air port valve according to the temperature in the ventilation duct, and the air port that parts can continue to use is with the automatic extending means of temperature control.
The utility model overcomes the above problems used technological scheme: provide a kind of air port with the automatic extending means of temperature control with following structure, it comprises the scaffold that is fixed on the valve housing, be fixed on fixed support on the scaffold, be packaged with memory alloy spring guide sleeve, be movably set in guide rod in guide sleeve one end, be movably set in stage clip on the guide sleeve the other end, be sleeved on travel(l)ing rest on the guide sleeve, be fixed on the installation foot on the valve blade; Said guide sleeve is provided with the limited step that is used for spacing stage clip stroke, and the fixed end of said stage clip is packed on the fixed support; One end and the memory alloy spring of said guide rod offset, and the other end stretches out guide sleeve and scaffold offsets; Said installation foot is movably arranged on the travel(l)ing rest.
The fixed end of said stage clip is packed on the fixed support and is meant, on the said fixed support press spring base is installed, and the fixed end of said stage clip is sleeved in the press spring base.
Said installation foot is movably arranged on the travel(l)ing rest and is meant, said travel(l)ing rest is provided with rotating shaft, and said installation foot is provided with the slotted hole that is rotatably assorted and vertically is provided with rotating shaft.
After adopting above structure; The air port of the utility model has the following advantages with the automatic extending means of temperature control: owing to the scaffold of this air port with the automatic extending means of temperature control is fixed on the valve housing, installation foot is fixed on the valve blade, when the temperature in the ventilation duct reaches or surpass the temperature value of memory alloy spring setting; The shape of memory alloy spring will change; Memory alloy spring can trail and make length elongated, thereby promotion guide sleeve and travel(l)ing rest move, and travel(l)ing rest moves and just drives the installation foot rotation; Thereby drive the rotation of valve blade, make valve closing; After the temperature in the ventilation duct was lower than the temperature value of memory alloy spring setting, memory alloy spring returned to original shape again, and stage clip promotes guide sleeve and travel(l)ing rest is got back to original position, thereby travel(l)ing rest makes valve open through driving the installation foot rotation.
Description of drawings:
Fig. 1 is the plan structure schematic representation of the air port of the utility model with the automatic extending means of temperature control.
Fig. 2 is the main TV structure schematic representation of the air port of the utility model with the automatic extending means of temperature control.
Shown in the figure: 1, scaffold, 2, fixed support, 3, guide rod, 4, guide sleeve, 4.1, limited step, 5, memory alloy spring, 6, stage clip, 7, press spring base, 8, travel(l)ing rest, 8.1, rotating shaft, 9, installation foot, 9.1, slotted hole.
Embodiment:
Below in conjunction with accompanying drawing and embodiment, the utility model done further describing:
A kind of air port as depicted in figs. 1 and 2 is with the automatic extending means of temperature control, it comprise through bolt be installed in scaffold 1 on the valve housing (not shown), through bolt be installed in fixed support 2 on the scaffold 1, be packaged with memory alloy spring 5 guide sleeve 4, be movably set in guide rod 3 in guide sleeve 4 one ends, be movably set in stage clip 6 on guide sleeve 4 the other ends, be sleeved on travel(l)ing rest 8 on the guide sleeve 4, be fixed on the installation foot 9 on the valve blade (not shown).Said guide sleeve 4 is provided with the limited step 4.1 that is used for spacing stage clip 6 strokes, and the fixed end of said stage clip 6 is packed on the fixed support 2.One end and the memory alloy spring 5 of said guide rod 3 offset, and the other end stretches out guide sleeve 4 and offsets with scaffold 1.Said installation foot 9 is movably arranged on the travel(l)ing rest 8.
The fixed end of said stage clip 6 is packed on the fixed support 2 and is meant, on the said fixed support 2 press spring base 7 is installed, and the fixed end of said stage clip 6 is sleeved in the press spring base 7.
Said installation foot 9 is movably arranged on the travel(l)ing rest 8 and is meant, said travel(l)ing rest 8 is provided with rotating shaft 8.1, and said installation foot 9 is provided with the slotted hole 9.1 that is rotatably assorted and vertically is provided with rotating shaft 8.1.
In the present embodiment, be sleeved on travel(l)ing rest 8 on the guide sleeve 4 between stage clip 6 and limited step 4.1.
During use; Earlier scaffold 1 is fixed on the valve housing at ventilation duct place, installation foot 9 is fixed on the valve blade, and when the temperature in the ventilation duct reaches or surpass the temperature value (being generally 70 ℃) of memory alloy spring 5 settings; The shape of memory alloy spring 5 will change; Memory alloy spring 5 can trail and make length elongated, thereby promotion guide sleeve 4 and travel(l)ing rest 8 move, and moving of travel(l)ing rest 8 will drive installation foot 9 rotations; Thereby drive the rotation of valve blade, make valve closing.After the temperature in the ventilation duct is lower than the temperature value (being generally 70 ℃) of memory alloy spring 5 settings; Memory alloy spring 5 returns to original shape again; Stage clip 6 promotes guide sleeve 4 and travel(l)ing rest 8 is got back to original position, thereby travel(l)ing rest 8 opens the valve blade through driving installation foot 9 rotations.
Certainly memory alloy spring 5 can change length with the variation of set temperature value, and this technology is a general knowledge, so not at this detailed description.
