Description

Technical Field

[0001] This utility model relates to the field of fireproof valve products, specifically a high-sealing, high-temperature fireproof valve. Background Technology

[0002] Fire dampers are typically installed on the supply and return air ducts of ventilation and air conditioning systems. They are normally open, but in the event of a fire, when the gas temperature inside the duct reaches 70°C, the fusible link melts, and the valve automatically closes under the force of a torsion spring. These dampers meet the requirements for fire resistance stability and integrity for a certain period, serving as smoke and fire barriers. When the valve is closed, it outputs a closing signal.

[0003] For example, patent application number CN201721658110.2 describes a high-sealing, high-temperature resistant fireproof valve, comprising a valve body and multiple blades. The valve body is composed of a longitudinal frame plate and a transverse frame plate. The longitudinal frame plate is provided with an actuator, a temperature sensor, a spring, and a shaft hole. The left and right ends of the blades are connected to a connecting rod device, and pressure plates are provided at both ends of the blades. A blade shaft is provided between the blades and the pressure plates, and the blade shaft is connected to the longitudinal frame plate through a shaft hole. This utility model has a reasonable structure, long service life, good airtightness, high temperature resistance, and extremely low thermal deformation rate, effectively ensuring smoke and fire prevention performance.

[0004] However, the aforementioned common high-sealing, high-temperature resistant fire dampers have the problem of being difficult to disassemble. When the fire damper body is damaged, it cannot be quickly and easily removed from the ventilation duct, causing great inconvenience to users. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] Please see Figs. 1-3 This utility model provides an embodiment of a high-sealing, high-temperature fireproof valve, comprising a pipe 1 and a fireproof valve body 2. The fireproof valve body 2 is disposed inside the pipe 1. The top of the pipe 1 has a spigot. The top of the fireproof valve body 2 passes through the spigot and is fixedly connected to a positioning plate 3. Fixing plates 4 are provided on both sides of the positioning plate 3. The fixing plates 4 are fixedly connected to the pipe 1. A locking plate 5 is slidably inserted into both ends of the fixing plate 4. A slanted groove 6 is provided at the top of one end of the locking plate 5. A connecting plate 7 is fixedly connected between two adjacent locking plates 5. One side of the connecting plate 7 is connected to the fixing plate 4. Multiple elastic mechanisms 8 are fixedly connected between the plates 4. The outer wall of the positioning plate 3 is provided with a slot corresponding to the card plate 5. The fire damper body 2 is aligned with the socket on the pipe 1 and inserted. During the insertion process, the bottom ends of the positioning plate 3 will press against the inclined groove 6 on the card plate 5. At the same time, the card plate 5 will move on the fixed plate 4 under the push of the positioning plate 3. At this time, the connecting plate 7 will squeeze the elastic mechanism 8. When one end of the card plate 5 is parallel to the slot on the positioning plate 3, the rebound force of the elastic mechanism 8 will cause the connecting plate 7 to push the card plate 5 back so that the card plate 5 is firmly locked in the slot.

[0022] In this embodiment, a sealing ring 9 is fixedly connected to the bottom of the positioning plate 3. The sealing ring 9 is made of rubber and can cover the outside of the socket to achieve the sealing effect of the pipe 1. A handle 10 is fixedly connected to the top of the positioning plate 3 to facilitate pulling the positioning plate 3. All the elastic mechanisms 8 are springs with high accessibility. The inclined groove 6 on one end of the clamping plate 5 is polished to reduce pressure resistance. The positioning plate 3 is provided with a through hole corresponding to the clamping plate 5, and the clamping plate 5 is slidably inserted into the through hole.

[0023] Working principle: During installation, the fire damper body 2 is inserted into the socket on the pipe 1. During the insertion process, the bottom ends of the positioning plate 3 will press against the inclined groove 6 on the clamping plate 5. At the same time, the clamping plate 5 will move on the fixing plate 4 under the push of the positioning plate 3. At this time, the connecting plate 7 will squeeze the elastic mechanism 8. When one end of the clamping plate 5 is parallel to the position of the groove on the positioning plate 3, the rebound force of the elastic mechanism 8 will cause the connecting plate 7 to push back the clamping plate 5 so that the clamping plate 5 is firmly clamped in the groove.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
