Description
Technical Field
The invention relates to the field of fireproof sealing valves, in particular to a valve locking device for a fireproof sealing valve.
Background
The fire-fighting smoke-discharging fireproof sealing valve is mainly installed at the inlet of a smoke-discharging fan, the smoke-discharging opening or when a fire-preventing subarea passes through and is used for controlling the fire to be automatically closed once the fire reaches a specific temperature; the valve plate of the fireproof airtight valve in the prior art can shake when meeting the resistance of wind and water, so that the operation of an actuating mechanism is unstable, and the service life of the fireproof airtight valve is shortened.
Disclosure of Invention
The invention aims to provide a valve locking device for a fireproof airtight valve, which has the advantages of simple structure and good use effect, and improves the use performance of the fireproof airtight valve; the technical problem is solved.
In order to achieve the technical purpose and achieve the technical requirements, the invention adopts the technical scheme that: the locking device for the fireproof airtight valve comprises a fireproof valve body; is characterized in that a cover plate is arranged above the fire damper, one end of the cover plate is provided with an air spring through a first rotating pin, the air spring is horizontally arranged, and the other end of the air spring is connected with an indicating needle; the other end of the cover plate is provided with a sign corresponding to the pointer; the center of the indicator needle is provided with a rotating shaft, and the rotating shaft is connected with a valve rod of the fire damper.
Preferably: the gas spring is connected with the indicating needle through a second rotating pin.
Preferably: and a space is arranged between the pointer and the cover plate.
Preferably: the indication board is fixed on the cover plate through rivets.
Preferably: the rotating shaft and the valve rod are coaxial.
The invention has the beneficial effects; a locking device for a fire-proof containment valve, compared to a traditional structure: one end of the cover plate is provided with a gas spring through a first rotating pin, and the other end of the gas spring is connected with the indicating needle; the gas spring is rotated along with the rotation of the pointer and rotates around the first rotating pin; the rotating shaft is connected with the valve rod, and the rotating shaft and the indicating needle generate locking force under the action of the gas spring, so that the valve rod and the valve plate cannot shake; the performance stability of the fireproof airtight valve is greatly improved; the valve opening degree can be clearly observed through the design of the indicating needle; the invention has simple and compact structure, good stability, safety and reliability, can effectively resist the resistance of wind and water, avoids the valve from shaking, improves the use effect of the fireproof airtight valve and prolongs the service life of the fireproof airtight valve. The valve is locked through the cooperation of the gas spring, the rotating shaft and the pointer, so that the actuating mechanism is always in a good, effective and safe functional operation state.

Detailed Description
In order to make the objects, technical solutions and advantageous technical effects of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments;
in the drawings: the locking device for the fireproof airtight valve comprises a fireproof valve body; the method is characterized in that: a cover plate 2 is arranged above the fire damper body 1, one end of the cover plate 2 is provided with an air spring 4 through a first rotating pin 3, the air spring 4 is horizontally arranged, and the other end of the air spring 4 is connected with an indicating needle 5; the other end of the cover plate 2 is provided with an indication plate 6 corresponding to the indication needle 5; the center of the indicator needle 5 is provided with a rotating shaft 7, and the rotating shaft 7 is connected with a valve rod 8 of the fire damper.
The gas spring 4 is connected with the indicating needle 5 through a second rotating pin 9; a space is arranged between the indicating needle 5 and the cover plate 2; the indication board 6 is fixed on the cover plate 2 through a rivet; the rotating shaft 9 and the valve rod 8 are arranged coaxially.
The invention is implemented specifically as follows: in the process of opening and closing the valve, the valve rod drives the valve plate to rotate, and because the rotating shaft is connected with the valve rod through the connecting piece, the rotating shaft synchronously rotates while the valve rod rotates, so that the indicating needle is driven to rotate, and the indicating needle points to the opening or closing of the indicating plate, so that the operation is clear; one end of the pointer connected with the gas spring assembly drives the spring to rotate around the first rotating pin; when the valve is completely opened or closed, the indicating needle generates locking force under the action of the gas spring, so that the valve rod and the valve plate cannot shake; the performance stability of the fireproof airtight valve is greatly improved. The invention has simple structure, good stability, safety and reliability, can effectively resist the resistance of wind and water, avoids the valve from shaking, improves the use effect of the fireproof airtight valve and prolongs the service life of the fireproof airtight valve. By locking the valve, the actuating mechanism is always in a good, effective and safe functional operation state.
The foregoing examples are given solely for the purpose of illustrating the invention and are not to be construed as limiting the embodiments, and other variations and modifications in form thereof will be suggested to those skilled in the art upon reading the foregoing description, and it is not necessary or necessary to exhaustively enumerate all embodiments and all such obvious variations and modifications are deemed to be within the scope of the invention.
