Example Embodiment

[0016] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0017] like figure 1 As shown, the buffer type explosion flame isolation device of this embodiment includes a casing 1 and a sleeve device arranged in the casing 1, a valve core 4, a valve core base 3, a reset device 6 and a positioning device 2, and the sleeve device includes a sleeve 7 and the valve stem 5, the valve core 4 is connected to the valve stem 5, and the valve stem 5 can move axially in the sleeve 7 and be positioned by the positioning device 2. The positioning device 2 includes a positioning rod and a positioning groove arranged on the valve stem. The positioning rod is perpendicular to the valve stem, and the positioning is realized by inserting the positioning rod into the positioning groove. The valve core 4 is connected with a sleeve device, and the sleeve device is connected with a reset device 6, which can move axially ...

Abstract

The invention relates to a buffer type explosive flame isolation device comprising a shell, and a sleeve device, a valve core, a valve core base, a reset device and a positioning device which are arranged in the shell, and the valve core is connected to the sleeve device; and the sleeve device is connected to the reset device, can be rotated in the shell axially, and located through the positioning device. The device adopts mechanical principles completely, without electrical components, and has the advantages of low operating cost and high reliability. The quick turnoff of the device within the time difference between explosive blast and explosive flame is ensured, and the seal of the joint surface is closed quickly; and quick positioning and reset after action are achieved.

Description

technical field [0001] The invention belongs to the field of safety and relates to a buffer type explosion flame isolation device. Background technique [0002] In the field of flammable gas and dust market, the industrial market space is huge. According to incomplete statistics, there are currently more than 60,000 enterprises in my country whose business involves the production, storage, and transportation of industrial combustible gas dust. In recent years, there have been many gas and dust explosion accidents, resulting in huge loss of life and property. But there is a lack of effective explosion control equipment. The buffer explosion flame isolation device is one of the effective explosion control equipment, which is used to isolate the explosion flame in the flammable gas and dust explosion pipeline, so that the explosion flame cannot spread to the back of the device and protect the pipeline and system behind the device . This technology is blank in China. Conte...
