On frame plate.
Preferably, the outside bending in continuous 90 ° of the crossing frame plate side 2 times, L-shaped structure, crossing frame plate centre are equipped with
Two symmetrical horizontal frame side's muscle, crossing frame plate inside are equipped with baffle.
Preferably, the outside bending in continuous 90 ° of the vertical frame plate side 2 times, L-shaped structure, vertical frame plate are equipped between two parties
Vertical frame side's muscle, vertical frame side's muscle is equipped with the support sealing strip of U-shaped structure, between the support sealing strip and vertical frame side's muscle are reserved
Gap.
Preferably, the blade is by blade body, blade side's muscle, elastic sealing strip, first party muscle, second party muscle, semicircle
Muscle forms, and the blade end reinforcing rib for having back-shaped structure is riveted on the first party muscle.
Preferably, the blade body is an integral molding structure with first party muscle, second party muscle, semicircle muscle, first party muscle
It is opposite with second party muscle protrusion direction.
Advantageous effect is：The utility model is rational in infrastructure, and service life is long, and air-tightness is good, especially under high temperature environment,
Its caloric deformation rate is extremely low, and Smoke prevention and the fire protecting performance of valve has been effectively ensured.

Specific embodiment
Below by non-limiting example, the utility model is expanded on further, understands the utility model.
With reference to figure 1-7, a kind of high leakproofness fire resistant valve, including valve body 1 and four blades 4, the valve body 1 is by indulging
Frame plate 10 and crossing frame plate 9 form, and the vertical frame plate 10 is equipped with executing agency 2, heat detector 3, spring 22 and axis hole 7,
4 left and right ends of blade are connect with linkage 6, and 4 both ends of blade are equipped with pressing plate 8, and blade is equipped between blade 4 and pressing plate 8
Axis 5, the sharf 5 are connected to by axis hole 7 on vertical frame plate 10.The utility model, can positive normal open usually in opening
Wind, when the fire occurs, when the temperature in pipeline reaches the temperature of the setting of heat detector 3, heat detector 3 gives executing agency 2 signal, makes
It obtains blade 4 to close, blocks ventilation shaft, play the role of completely cutting off burning things which may cause a fire disaster, block flue gas.
The innovation of the utility model is, the continuous 90 ° of outside bendings of the crossing frame plate 9 and 10 side of vertical frame plate
