摘要： PURPOSE:To prevent deformation of a sealing material resulting from the gravitation when sealing a vertical clearance and keep an appropriate shape to securely seal a dome. CONSTITUTION:Vertical wall tubes 84, 86 are fitted to vertical walls 78, 80 respectively, which are separated when opening a dome and brought to their approach when closing. The vertical wall tubes 84, 86 get in contact with each other in the closed condition of the dome to seal the clearance between the vertical walls 78, 80. A cylinder rod 90 equipped with a pressing plate 94 is contained in the vertical tubes 84, 86, respectively. A cylinder body 92 is fixed at the opposite side against the arranged side of the vertical wall tubes 84, 86 in the vertical walls 78, 80 so as to extend or contract the cylinder rod 90 by the hydraulic pressure. As the vertical wall tubes 84,86 are laterally pressed with the pressing plate 94 by the extension of the cylinder rod 90, the vertical wall tubes 84, 86 are loosened resulting from the gravity and hence, they are mutually made close.

摘要： PURPOSE:To reduce the power requirement of fan and maintain a high level of ventilation efficiency by providing a lock key device which normally biases the roller to the damper in the radial direction of the lock bearing member. CONSTITUTION:A lock key device 20 is disposed above a lock bearing member 22. Where the static pressure inside the duct, for instance, is 5mmAq, if the wind pressure of outside air is less than that value, the weight of a balance weight 24 overcomes the wind pressure to cause a vane 16 to close the duct opening, and a roller 30 is locked in place by the engagement with the lock bearing part 25 of the lock bearing member 22. When the wind pressure of outside air exceeds 5mmAq, the engagement of the roller 30 with the lock bearing part 25 is released to allow the roller 30 to slide on the circumferential surface of the lock bearing member 22, which then rotates to open the vane 16. In the event the ventilation fan motor is operated, the vane 16 is automatically opened, whereas the vane 16 is closed to interrupt the outside air when the fan motor is stopped and the rush of outside air into the room is to be prevented.

摘要： PURPOSE:To make it possible to unfailingly detect the flow of a wind with accuracy regardless strong winds and/or a turbulent flow by installing a photoelectric sensor in non-floating or floating part of the floating element of a guiding portion. CONSTITUTION:A floating element 9 which is caused to float up by the flow 8 of a wind through a standing tubular guiding portion 7 is provided within the guiding portion 7, and shelfs 26 for preventing the floating element 9 from getting out of the portion are provided in upper and lower openings 7a, 7b of the guiding portion 7, respectively, and the opening 7b of its lower end is mounted thereto so as to be in contact with the flow 8 of a wind. The ends of a projecting cable 10a and a light receiving cable 10b each of which ends is carried out of a photoelectric sensor 10 are mounted to respective mounting portions of the non-floating part of the floating element 9 of the guiding portion 7 so as to form a light projecting portion and a light receiving portion, respectively. Light signals output from the light projecting portion are reflected by the floating element 9 during the absence of the flow 8 of a wind so as to be put in the light receiving portion, which detects the absence of the flow of a wind accordingly. The floating element 9 moves upwardly during the presence of the flow 8 of wind so that light signals output from the light projecting portion will not be put in the light receiving portion because of the absence of the reflecting face of the floating element 9, and the flow of a wind is thereby detected.

摘要： PROBLEM TO BE SOLVED: To provide a constant pressure release damper formed that a blade is released at a stretch when wind passing through a damper frame exceeds a set wind pressure, and airtightness during full closing can be ensured. SOLUTION: The constant pressure release damper comprises a lock receiving body 32 having an arcuate part 34 fixed at the shaft end of a rotary shaft protruded outward and a lock support part 36; a roller 22 rolled in adhesion to the arcuate part 34 of the lock support body 23 and engaged with and disengaged from the lock support part 36 of a lock support body 32; and a lock device 26 energizing in direction in which the roller 22 always approaches the lock support body 32. Further, the lock support part 36 has a slope 58 situated such that the roller 22 is forced upward in a direction to approach the lock support body 32 in synchronism with closing rotation of the blade 16 formed in succession to the arcuate part 34. When the blade 16 fully closes a flow passage V, the roller 22 is positioned only on the slope 58, security of full closing of the flow passage during setting of a balance between a wind pressure and a gravity moment around a rotary shaft and closing of the blade is reliably executed.

摘要： PURPOSE: To provide an inexpensive fixed pressure open damper capable of an highly accurate adjustment of set air pressure and being simply fabricated in a short time. CONSTITUTION: This damper comprises a rotary shaft 14 penetrating a damper frame, a blade fixed to the rotary shaft 14, a rocking receptor 32 having a circular arc-shaped surface 34 and a rocking receptor part 36, a balance weight for energizing the blade in the direction of closing a flow passage, a roller 22 rolling on, in close contact with, the circular arc-shaped surface 34 and detachably engaging with the rocking receptor part 36 of the rocking receptor 32, and a rocking device 26 for energizing the roller 22 radially of the rocking receptor 32 at all times. The rocking receptor part 36 has a slope 58 formed continuously with the cricular arc-shaped surface 34 whereby when the blade closes the flow passage, the roller 22 is located on the slope 58 and hence a frictional component is reduced to ensure setting of stable air pressure.
