Fireproof valve for oil smoke pipeline of setting machine

Abstract

The invention discloses a fireproof valve for an oil smoke pipeline of a setting machine, which has convenient disassembly and assembly and can rapidly induct a fire alarm signal. The fireproof valve comprises a shell, and one side of the shell is respectively provided with a track-type valve core mounting cavity and a track-type fire alarm sensor mounting cavity; a valve core and a fire alarm sensor are respectively arranged in the track-type valve core mounting cavity and the track-type fire alarm sensor mounting cavity. The invention has the advantages that the fireproof valve with the structure, which is used in the oil smoke pipeline of the setting machine, is easy to disassemble and install, and thereby, cleaning and maintaining the inside of the fireproof valve are convenient. Simultaneously, the fire alarm signal can be rapidly inducted, and then a channel between the oil smoke pipeline and the setting machine is cut off so as to prevent fire from spreading, prevent blades from deformation for a long time and prolong the service life of the fireproof valve.

Description

technical field [0001] The invention relates to a fire damper, in particular to a fire damper used in oil fume pipes of setting machines. Background technique [0002] The setting machine is a machine used to dry and arrange fabrics such as cloth to make them shape. When the oil fume passes through the oil fume pipe, it is very easy to catch fire. Once the fire spreads, it will be difficult to control, and even the whole setting machine and the fabric on the setting machine will be burned, causing relatively large economic losses. In order to control the spread of fire in the oil fume duct, a fire damper is generally arranged in the oil fume duct of the setting machine. The structure of the existing fire damper includes: a casing, an actuator arranged on one side of the casing, a vane group and a thermal melting device arranged in the casing. The hot-melt device is composed of a bracket, a spring pull rod arranged in the bracket and a hot-melt sheet arranged in the bracket...

AI Technical Summary

Problems solved by technology

However, during long-term use, oily fume tends to accumulate in the oily fume pipe and fire damper, and the blade group is stuck, and the opening and closing operations cannot be realized, which affects the normal operation of the fire damper

Therefore, the inside of the fire damper needs to be cleaned and maintained frequently, but the disassembly and installation of the fire damper with the above structure is very troublesome, which brings a lot of inconvenience to the cleaning and maintenance work.

At the same time, when a fire breaks out in the oil fume pipe, the hot-melt device with the above structure has fewer trigger points and takes a longer time to sense the fire signal. After a long time of fire, the blade group will heat up and expand, deformed, and cannot be opened and closed.
