Abstract
The utility model relates to a wind valve with wind-exhaust and fireproof two purposes. The wind valve with wind-exhaust and fireproof two purposes is composed of a circular outer disk, a circular bottom disk, a screw, a transverse strut, and a positioning nut. The wind valve with wind-exhaust and fireproof two purposes is characterized in that a gap is arranged between the circular outer disk and the circular bottom disk. A fusible sheet 7 is connected between a bearing sheathed on the screw and a position limiting nut. The wind valve with wind-exhaust and fireproof two purposes can be used as a wind supply opening and a wind discharge opening at ordinary times, the fusible sheet is automatically broken when the fusible sheet encounters a fire, and a wind intake opening is closed. The circular outer disk is disassembled after the fire, then, the fusible sheet can be replaced, and the wind valve with wind-exhaust and fireproof two purposes can continuously work. The utility model has the advantages of simple structure, and convenient installation and maintenance. Compared with the common vent plus a fireproof valve, the wind valve with wind-exhaust and fireproof two purposes can save initial investment 50%.
Description
The utility model belongs to the air-supply exhaust port and the fire-protection valve of air-conditioning equipment.
At present, all be provided with an air-supply, exhaust port in the room in restaurant and the toilet, it is connected on the airduct mouth of central air conditioning, to indoor air-supply, air draft, the air port is generally louvre ventilation, and when meeting fire, flue gas upwards enters air-conditioning duct from air-supply, exhaust port, spread to other rooms, the people who makes the room that does not have fire is because of flue gas death by suffocation.What have is provided with a fire-closing valve in ventilation duct, can close automatically when running into fire, but recover behind the fire to use also need enter in the narrow furred ceiling in work-yard to repair, and gives to use and safeguard at ordinary times to make troubles.
The purpose of this utility model is, designs a kind of air draft dual-purpose air-valve of preventing fires, and replaces existing air-supply, exhaust port, do air-supply, the exhaust port of central air conditioning at ordinary times, can close air intake, air draft air port automatically when running into fire, isolated flue gas, and recover use and easy to maintenance at ordinary times simple.
The air draft of the present utility model dual-purpose air-valve of preventing fires is made up of the outer dish 1 of circle, circular base plate 2, screw rod 11, horizontal support 4 and setscrew nut 6, it is characterized in that: circular outer dish 1 is one tubaeform, and osculum makes progress; Protrude on circular base plate 2 surface, acclivitous edge in periphery is oriented, in connect a long bolt 11, be installed in the Da Kouchu of circular outer dish, and leave the space between circular outer dish; The suitable for reading of dish has one to fix horizontal support 4 outside circle, screw rod 11 passes horizontal support, at top cover one location nut 6, horizontal support top is with spring 9 and stop nut 10 on screw rod, it is the balladeur train 5 of flute profile that stop nut 10 laterally connects a section, and the balladeur train bottom is stuck in the horizontal support, but the central position of standing screw, and along with screw rod moves up and down, the relative spring sheet 12 that is provided with in horizontal support with balladeur train plays the location point action; On the bottom screw rod that supports, be with the bearing 3 that screw rod is moved up and down; Be connected a fuse sheet 7 10 of bearing 3 and stop nuts, but bullet on the restraining spring 9 makes circular base plate 2 and circular outer dish 1 keep ventilation voids.
The air draft of the present utility model dual-purpose air-valve of preventing fires, during installation, the two ends of horizontal support and a fixing nail 8 on the circular outer dish are plugged on the air conditioning wind pipe mouth, wind coils suitable for reading entering outside circle, pass in the space inlet chamber of circular outer dish and circular base plate, the adjusting air quantity is 80-120M
3/ h; When fire occurring, when the flue-gas temperature by air draft fire prevention dual purpose valve reaches 70 ℃, the fuse sheet 7 that is connected to 10 of bearing 3 and stop nuts breaks, spring 9 power out of hand on horizontal support top and go up bullet, driving long bolt 11 moves upward, circular base plate rises and the driving fit of circular outer dish simultaneously, thereby reaches the purpose that isolated flue gas passes through.After fire, as long as circular inverted position turn is changeed, fixing nail 8 leaves airduct 13, with regard to replaceable fuse sheet, and the dual-purpose air-valve proper functioning again but air draft is prevented fires.
The air draft of the present utility model dual-purpose air-valve of preventing fires can adopt copper material or stainless steel material to make.
The air draft of the present utility model dual-purpose air-valve of preventing fires has simple in structurely, installs and to overhaul advantage easily, adds fire-closing valve than general air port and saves and once invest 50%, economic benefit and obvious social benefit.
Below in conjunction with drawings and Examples the air draft of the present utility model dual-purpose air-valve of preventing fires is described further.
Fig. 1 is the air draft dual-purpose air-valve planimetric map of preventing fires
Fig. 2 is the prevent fires I-I sectional drawing of dual-purpose air-valve of air draft
Fig. 3 is the prevent fires II-II sectional drawing of dual-purpose air-valve of air draft
As seen from the figure, the air draft dual-purpose air-valve of preventing fires is made up of the outer dish 1 of circle, circular base plate 2, screw rod 11, horizontal support 4 and setscrew nut 6, and circular outer dish is a toroidal, and osculum makes progress, and back cut diameter is 65 millimeters, and lower port diameter is 100 millimeters; The circular base plate diameter is 100 millimeters, connects a long bolt 11 in the circular base plate; Circular base plate is positioned at the Da Kouchu of circular outer dish, and the space is 30 millimeters; The suitable for reading of dish has one to fix horizontal support 4 outside circle, screw rod 11 passes horizontal support, at top cover one location nut 6, horizontal support top is with spring 9 and stop nut 10 on screw rod, it is the balladeur train 5 of flute profile that stop nut laterally connects a section, the balladeur train bottom is stuck in the horizontal support, and the horizontal support in the position relative with balladeur train is provided with a spring sheet 12; On the bottom screw rod that supports, be with the bearing 3 that screw rod is moved up and down; Be connected a fuse sheet 7 10 of bearing 3 and stop nuts, bullet on the restraining spring 9 makes between circular base plate and the circular outer dish to keep ventilation voids.
