Abstract
The invention discloses an anti-explosion sensor shield. The anti-explosion sensor shield comprises an anti-explosion shell and a protective skirt and is characterized in that the bottom of the anti-explosion shell is connected with the protective skirt; an anti-explosion thread is arranged outside the upper end of the anti-explosion shell; an inner cavity is formed inside the anti-explosion shell; a cavity anti-explosion thread is arranged in the position where the bottom of the inner cavity is connected with the protective skirt; a circumference hole is formed at the joint of the anti-explosion shell and the protective skirt; a detection cavity is formed inside the circumference hole; the lower end of the detection cavity is connected with plane circular holes. The anti-explosion sensor shield has the beneficial effects that two vent hole structures are not only used for rapidly guiding detection gases to enter and exit from a sensor but also protect the sensor from being affected by adverse factors, such as wind and rain.
Description
Technical field
the present invention relates to a kind of protective cover, be 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 patent of the present invention is not enough and proposes for solving appeal just, adopts rational structural design, guaranteeing, under the prerequisite that windproof, rainproof, portable adjusting is demarcated, to invent the object not affecting sensor performance.
Summary of the invention
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 invention provides a kind of explosion-proof sensor protective cover, comprise explosion-proof casing, protection skirt, it is characterized in that: bottom described explosion-proof casing, connecting protection skirt; 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 invention has the beneficial effects as follows: 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.
