Abstract
The invention discloses a fireproof valve blade. The longitudinal sides of two single blades (5) are articulated so as to form an airfoil double-layer blade. Since the longitudinal sides of the single blades are articulated so as to form the airfoil double-layer blade, the fireproof valve blade deforms slightly under a high-temperature fireproof test condition as compared with a single blade. According to the invention, the seal property and fireproof property of the fireproof valve are improved, the air leakage rate of the valve is reduced, the fireproof valve blade fills up the blank of the domestic fireproof valve airfoil-free-type double-layer blade, and can be widely applied to nuclear power projects and other foreign or domestic construction projects with high-standard fireproof rating requirements.
Description
Technical field
The present invention relates to the fire-protection valve device that a kind of building uses, particularly a kind of fire-closing valve blade.
Background technique
In some important buildings, almost be equipped with Automatic fire a1arm system, need fire-closing valve be set at the response position of air conditioner and smoke control system.Fire-closing valve; Be installed on the specific position that fire protection requirement is arranged (fire barrier wall or floor) of the sending of ventilation and air conditioning system, return air pipeline; Fire-closing valve is often opened at ordinary times, and when breaking out of fire, it is when gas temperature reaches 70 ℃ in the pipeline that the interior air-flow of pipeline reaches controlled temperature; Thermal link fusing, valve is closed under the effect of torsion spring power automatically.Can satisfy Fire stability and Fire integrity requirement within a certain period of time, play valve at a distance from the effect of cigarette back-fire relief.Behind the fire, change thermal link and open fire-closing valve again.Existing fire-protection valve connects actuator by the blade type valve body, and following technological deficiency is arranged: 1, blade does not adopt elongated axle to reinforce, and rigidity is low; Receive blast and be heated after all yielding; The valve inleakage is big, and fire performance is poor, and is especially obvious for big specification valve.2, at present domestic fire-closing valve is the individual layer blade, and fire resistance rating is 1.5 hours, can not reach the nuclear power USS United States Standard, promptly fire resistance rating be 3.0 hours requirement and domestic single blade when fire testing, be easy to distortion.
Summary of the invention
The objective of the invention is to the present invention and propose a kind of improved fire-closing valve, solve the problem that the valve inleakage is big, fire performance is poor, working life is short, actuator's bearing capacity is low.
The technological scheme that realizes the object of the invention is: a kind of fire-closing valve blade; By blade type valve body and actuator; The blade type valve body comprises that external frame, connecting rod driver plate, said connecting rod driver plate link to each other with the sharf dunnage; Single blade is closed the extension spring sheet with being arranged on the valve, and single sharf penetrates on the shaft shoulder support that is fixed on the housing, and actuator comprises main shaft and the auxilliary axle that matches with it; Said main shaft penetrates through collar bush and is fixed on the external frame, and being articulated and connected by two said single blade longitudinal edges is the aerofoil profile twi-tier blade.
The present invention has following beneficial effect: single blade longitudinal edge is articulated and connected and is the aerofoil profile twi-tier blade; Make it under the high-temperature flame-proof test conditions; Micro-strain only takes place in more single blade, has improved sealing and refractory nature, has reduced the valve inleakage; This fire-closing valve blade has been filled up the blank of domestic fire-closing valve all-body configuration twi-tier blade, other concerning foreign affairs or domestic construction projects that can be widely used in nuclear power engineering and have the high standard fire resistance rating to require.

Embodiment
See a kind of fire-closing valve blade of Fig. 1; By blade type valve body and actuator; See that Fig. 2 and Fig. 3 blade type valve body comprise that external frame 1, connecting rod driver plate 2, said connecting rod driver plate 2 link to each other with sharf dunnage 4, single blade 5 is closed extension spring sheet 6 with being arranged on the valve, and single sharf penetrates on the shaft shoulder support 8 that is fixed on the housing; Actuator comprises main shaft 7 and the auxilliary axle 9 that matches with it; Said main shaft 7 penetrates through collar bush 3 and is fixed on the external frame 1, sees Fig. 4, and being articulated and connected by two said single blade 5 longitudinal edges is the aerofoil profile twi-tier blade.Its working procedure is: double-leaf is the mode of being crossed the structure that is hinged by two single blade pass, and is compressed together two longitudinal edges, makes them under 1052 ℃ of high-temperature flame-proof test conditionss, and micro-strain only takes place more single blade, and Deformation control is within critical field.
Should be appreciated that specific embodiment described above only is used to explain the present invention, and be not used in qualification the present invention.Conspicuous variation of being extended out by spirit of the present invention or change still are among protection scope of the present invention.
