Background technology

Fire resisting damper and smoke exhaust fire damper are mainly made of valve body, blade, executing agency and heat detector, installed in mechanical smoke extraction On pipeline, usually in opening, meet that smoke evacuation requires within a certain period of time, when flue-gas temperature reaches 280 in smoke discharging pipe DEG C (smoke exhaust fire damper)/70 DEG C（Fire resisting damper）When, executing agency's action automatic-closing valve, current fire resisting damper and smoke-exhaust fire Valve has the following disadvantages：

First, the blade of fire resisting damper and smoke exhaust fire damper is synchronized between blade by linkage combination there are multi-disc Be turned on and off, for obstructing the circulation of flue gas, linkage is located at valve inner, and by high temperature to be influenced service life short；Blade Between and the structure of sharf and valve body at there are gap, can not be effectively treated.

2nd, the contact point of tabletting and valve body is more, have impact on the strength of executing agency's tension spring accordingly, for a long time using influence The use of fire resisting damper and smoke exhaust fire damper.

3rd, the opening direction of blade is different, cares for the side block aerofoil coordinated with blade as split structure and is located at valve body two Side, causes inleakage not controlled.

4th, the opening and closing of fire resisting damper and smoke exhaust fire damper are realized by executing agency's internally installed pull-spring, the drawing of the tension spring Power is smaller, can not make between blade, overlap joint combines completely between blade and valve body, causes inleakage not controlled.

The content of the invention

Technical solution is used by the utility model solves its technical problem：

A kind of novel fire damper, including valve body, executing agency, heat detector and blade, it is characterised in that：In the valve body Middle side part is equipped with central fixing bracket, and central fixing bracket both sides are respectively equipped with a piece of blade, and two blades inner sides are It is connected between Internal baffle and blade by sharf equipped with Internal baffle matched with central fixing bracket and with valve body, two blades It can be equipped with and the matched side block aerofoil of blade, the sharf both ends towards valve body the same side Unscrew and valve body opposite side Valve body is stretched out respectively to set and be connected with each other by link mechanism, link mechanism is also connected by external tension spring with valve body, wherein One sharf is connected with the executing agency.

The link mechanism includes con-rod only and the connection sheet positioned at con-rod only both ends, and con-rod only passes through company Contact pin and corresponding blade axis connection.

The central fixing bracket is a plate body, and the support bracket fastened left and right sides in center matches and seals with valve interior wall Connection, both sides are horizontal section to central fixing bracket up and down.

The side block aerofoil is one and the matched ring-type plate body of valve interior wall.

The sharf is connected by axle sleeve with body wall.

The heat detector is arranged on valve interior wall.

In conclusion the beneficial effects of the utility model are：Reasonable in design, sealing effect is good, simple production process, It is efficient, the operating flexibility of fire resisting damper is improved, can meet the control to inleakage, comply with national standard, can be used Used in fire resisting damper and smoke exhaust fire damper.
