Embodiment Construction

[0028] A temperature-sensing glass bulb temperature control switch, which includes a body (1), a locking screw (2), a temperature-sensing glass bulb (3), a plug (4), a push rod (5), and a guide copper sleeve (6) , spring (7), terminal post I (8), terminal post II (9), conductive block (10), lock nut (11).

[0029] The body (1) is designed as a cavity structure.

[0030] The plug (4) is installed on the step edge of the inner through hole of the body (1).

[0031] The plug (4) divides the inside of the body (1) into two parts, an upper cavity and a lower cavity.

[0032] The locking screw (2) is screwed into the central screw hole on the upper end of the body (1).

[0033] The temperature-sensing glass bulb (3) is installed inside the upper cavity of the body (1), the lower part of the temperature-sensing glass bulb (3) is installed in the central concave hole on the upper end of the plug (4), and the temperature-sensing glass bulb (3) The upper part is compressed by the loc...

Abstract

The present invention discloses a temperature sensing glass ball temperature control switch. The switch mainly comprises a body 1, a locking screw 2, a temperature sensing glass ball 3, a plug 4, an ejection rod 5, a guidance copper bush 6, a spring 7, a binding post I8, a binding post II9, a conduction block 10 and a locking nut 11. The materials of the ejection rod 5 are insulated, heat-resisting and anti-corrosion plastics, and an end face of the locking nut 11 is provided with a plurality of radial equidistant ventilation opening holes. The temperature sensing glass ball temperature control switch employs the temperature sensing glass ball 3 as a temperature sensing element, when the temperature of a fire scene reaches a nominal motion temperature of the temperature sensing glass ball3, the temperature sensing glass ball 3 is broken, the temperature control switch automatically connects with a switching circuit, and therefore a purpose of effects of a fire extinguisher plant is achieved, and the switch provided by the invention is simple in structure, reliable in effect and low in cost, etc.

Description

technical field [0001] The invention relates to a temperature-sensing glass bulb temperature control switch, which uses a temperature-sensing glass bulb as a temperature-sensing element to realize automatic switching on of the temperature control switch, and is especially applied to a hanging or floor-standing non-pressure-storage hot aerosol automatic fire extinguishing device. Background technique [0002] In the background technology, temperature-sensing glass bulbs are used as a temperature-sensing element, and have been widely used in glass bulb temperature-sensing nozzles. The temperature-sensing nozzles are mainly used in stored-pressure ultra-fine dry powder fire extinguishing devices and fire-fighting sprinkler systems. When the ambient temperature of the fire scene reaches the nominal operating temperature of the temperature-sensing glass ball, the temperature-sensing glass ball is broken, and the valve on the temperature-sensing sprinkler head is opened. Water is ...
