Valve for remote fuse control

Abstract

The invention relates to a valve for remote fuse control. The valve comprises a valve body, an oblique valve plate is hinged on the valve body, and the outer walls of the left and right sides of the valve body are provided with a left connecting rod body and a right connecting rod body; a tension spring is installed on a tension spring card, and the lower end of the tension spring connected with the connecting rods I and II; connecting rod pressing plates are also arranged on connecting rod base plates, the connecting rod pressing plates are connected with the middles of the two connecting rods by a fusing pin shaft, the tail ends of the two connecting rods are connected with the front end of a steel cable by a cable clamp, and the tail ends of the two steel cables on the left and right connecting rod bodies are simultaneously connected with a pushing rod motor assembly; the valve is the improved scheme based on the existing technical scheme and is also a brand-new scheme; although theimprovement is relatively simple, the valve can improve the sensitivity and reliability of the reaction in the event of a fire greatly, so that the fire performance of the valve is further and substantially improved.

Description

technical field [0001] The invention relates to the technical field of oil fume purification equipment, in particular to a valve with remote fusing control. Background technique [0002] In the current market, especially in hotel and restaurant kitchens that use more stoves or other industrial systems that involve multiple exhaust fumes, the fire damper currently used is a general damper, which is not installed inside the smoke hood. Special air valve. Most of the upwind valves on the market now have a square valve body. At present, there is no smoke hood with an inclined damper inside the smoke hood on the market. Most of the oil exhaust hoods on the market are controlled by one fan. When the stove is cooking and cooking, the fan must be turned on at full load, which is an extreme waste of electric energy, and the energy saving situation is extremely unsatisfactory. Moreover, such an oil fume exhaust system is not ideal for the single oil fume exhaust area in the system. ...

Problems solved by technology

Most of the upwind valves on the market now have a square valve body. At present, there is no smoke hood with an inclined damper inside the smoke hood on the market. Most of the oil exhaust hoods on the market are controlled by one fan. When the stove is cooking and cooking, the fan must be turned on at full load, which is an extreme waste of electric energy, and the energy saving situation is extremely unsatisfactory. Moreover, such a fume exhaust system is not ideal for the single fume exhaust area in the system.

[0003] Of course, there are currently technical solutions involving the fire-proof hood damper structure, such as the technical solutions described in the patent applications with application numbers 201910489289.0 and 201910489301.8, that is, once a fire occurs under the fume hood, the temperature reaches A certain fusing value, the temperature sensor on it will feed back the temperature to the electric actuator, and the action of the electric actuator can pull the inclined valve plate back and close the fire protection. At the same time, some of them use tension springs to help reset operating mechanism, but the above-mentioned mechanisms have shortcomings at the same time, that is, once there is a problem with the executive mechanism, or the electronic control mechanism fails, the fire protection function will not be realized, leaving a huge fire hazard, and because the oil fume purification equipment itself The working environment is quite bad. With the increase of service time, the probability of failure of these mechanisms will greatly increase, which in turn increases the safety hazard of fire.
