Description
Technical field
The utility model relates to vibration-detecting instrument technical field, specifically a kind of explosion-proof vibration-detecting instrument.
Background technology
The wide range of vibration-detecting instrument application; for different working environments; vibration-detecting instrument needs different performances; easily producing in the working environment of inflammable gas, due to vibration-detecting instrument operationally, can electric spark be produced; common vibration-detecting instrument does not have corresponding safeguard measure; electric spark meeting ignited flammable gas, cause blast, this is quite dangerous.
Utility model content
For solving the problem, the utility model discloses a kind of explosion-proof vibration-detecting instrument, comprise: mounting casing, vibration detection circuit plate, explosion-proof shell, Explosion-proof cap, binding post, O-ring seal, described vibration detection circuit plate is fixed in mounting casing inside, described explosion-proof shell is threaded connection on mounting casing top, described binding post is screwed in explosion-proof shell inside, described Explosion-proof cap is connected with explosion-proof shell by screw thread, and junction is lined with O-ring seal, described binding post is connected by wire with vibration detection circuit plate, described explosion-proof shell exit is provided with O-ring seal.
The utility model is a kind of explosion-proof vibration-detecting instrument, can use under the working environment easily producing inflammable gas, by arranging O-ring seal at Explosion-proof cap and explosion-proof shell junction, explosion-proof shell exit, make inflammable gas cannot enter vibration-detecting instrument inside, thus the spark making vibration-detecting instrument produce cannot ignited flammable gas, stop the generation of exploding.
The utility model has the advantages such as structure is simple, safe and effective.
Accompanying drawing explanation
