Description
Technical field
the utility model relates to a kind of protective cover, is specially a kind of explosion-proof sensor protective cover.
Background technology
at industrial circles such as oil, chemical industry, smelting, pharmacy, gas detector is the professional instrument effectively detecting toxic and harmful, bears the important task of gas security alarm.The core detecting element of the Industrial Solid fixed pattern gas detector on market today is sensor, and the parameter such as accuracy of detection, response time of gas detector all has direct relation with the protective cover of sensor.And although the sensor protective shield that the gas detector product that most manufacturers is produced at present adopts is of a great variety, but there is the defect that one is common, ensure to some extent the response time, but to weak to weather protection rank, high to weather protection rank, but the response time is affected to some extent, also or to the operation that the debugging of detector is demarcated brings obstruction.
and the utility model patent is not enough and proposes for solving appeal just, adopt rational structural design, under the prerequisite guaranteeing windproof, rainproof, portable adjusting demarcation, utility model does not affect the object of sensor performance.
Utility model content
the technical matters with weight is amassed in order to solve above-mentioned casting machine support body, this full mold provides a kind of water test unit to replace casting frame, this device not only simplifies the operation system, and significantly reduces volume and the weight of hydraulic testing equipment, and is applicable to the hydraulic testing of small size flameproof enclosure.
in order to solve the problems of the technologies described above, the utility model provides a kind of explosion-proof sensor protective cover, comprises explosion-proof casing, protection skirt, it is characterized in that: connect protection skirt bottom described explosion-proof casing; Be provided with explosion-proof screw thread outside described explosion-proof casing upper end, explosion-proof casing inside is provided with inner chamber; Described intracavity bottom connects protection skirt place and is provided with the explosion-proof screw thread of cavity; Described explosion-proof casing and protection skirt junction are provided with circumferential apertures; Described circumferential apertures inside is provided with test chamber; Described test chamber lower end connects plane circular hole.
the beneficial effects of the utility model are: two groups of vent hole structures not only guide fast and detect gas turnover sensor, and play the protective action that sensor can not be subject to the unfavorable factor impacts such as wind and rain.
