Embodiment

[0024] In order to make the above-mentioned features, methods, purposes and advantages of the present invention more obvious and easy to understand, in conjunction with the accompanying drawings, it is described as follows:

[0025] figure 1 A cross-sectional view of a preferred embodiment of a sprinkler using a differential pressure switch provided by the present invention is shown.

[0026] The spraying device of the present invention includes a differential pressure switch 101 , a pressure sensing component 102 , a spraying element 103 , an upper cover 105 , a base 106 and an airtight bag 107 . Wherein, the spraying element 103 is fixed in the upper cover 105 and externally connected to the material supply device 100 for supplying the spraying material 109 . In addition, the spraying element 103 also includes a spraying head 110 as an outlet for the spraying material 109 .

[0027] The spraying device of the present invention is connected on the air duct wall 108 of the e...

Abstract

The pressure difference type spraying device for exhausting air duct apparatus includes spraying element, sealing bag to cover the spraying head, pressure sensing element and pressure difference switch. When the sealing bag breaks, the internal pressure change will be detected via the pressure sensing element and reflected to the pressure difference switch, and when the pressure change reaches the range for the pressure difference switch to act, the pressure difference switch will start the spraying element to spray material.

Description

technical field [0001] The invention relates to a differential pressure spraying device, in particular to a differential pressure spraying device used in an exhaust air duct. Background technique [0002] Because the equipment and pipelines inside the general factory are very complicated and hide many dangerous factors that can cause fires, among them, the exhaust duct equipment used to transport gas is a closed space and the interior is mostly flammable gas, so it is quite easy to cause a fire. Therefore, fire prevention devices that can react and deal with fire phenomena in real time are necessary equipment. Usually, this type of fire prevention equipment uses an automatic sprinkler as a fire prevention device in the exhaust duct, and uses the included spray water mist, water, or other Various fire extinguishing substances are used to extinguish the flames. [0003] The traditional automatic spraying device erected on the exhaust air duct is generally used to protect the...
