Description
Technical Field
The utility model relates to a fields such as meteorological, atmospheric pressure altitude measurement specifically are an external tubing assembly of baroceptor for meteorological affairs.
Background
The air pressure sensor is used for measuring the air pressure, and the application range of the products is greatly limited because some air pressure sensors cannot be directly used in the environments of damp heat, sand dust and the like. When a user uses the product in the environments of damp heat, sand dust and the like, a certain protection measure needs to be taken, and a damp-proof and dustproof device is usually installed as the protection measure taken by the user. But the volume of the moisture-proof and dust-proof device is larger, which brings inconvenience to users.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem who solves: the problem of atmospheric pressure sensor dampproofing, dustproof is solved, current dampproofing, dustproof measure is generally handled by the user by oneself, brings very big inconvenience for the user uses. The user can not reach dampproofing, dustproof effect very effectually under the prerequisite of not knowing this type of baroceptor structure mechanism. The invention combines the structure and performance characteristics of the product, so that a user does not need to carry out damp-proof and dust-proof design by himself when using the air pressure conduit assembly, and the air pressure conduit assembly can be directly used as an accessory, so that the air pressure conduit assembly is more convenient for the user to use.
The technical scheme is as follows:
the utility model provides an external conduit component of a meteorological air pressure sensor, which comprises a pipe joint and a spiral conduit; at least the outlet end of the spiral conduit is fixedly connected with a pipe joint; the pipe joint is adapted to a gas pressure sensor, and is capable of guiding gas to the gas pressure sensor.
Furthermore, the number of the pipe joints is two, the first pipe joint is fixedly arranged at the outlet end of the spiral conduit and matched with the air pressure sensor, and the second pipe joint is fixedly arranged at the inlet end of the spiral conduit and serves as a universal joint. The universal joint is used for connecting or communicating with other external equipment or pipelines.
Further, the pipe joint is connected with the spiral conduit in a bonding, welding, threaded connection or tight fit mode.
Furthermore, the pipe joint is made of plastic, carbon fiber, rubber, metal or composite materials.
Furthermore, the spiral conduit is made of plastic, carbon fiber, metal or composite materials. Preferably stainless steel.
Furthermore, the number of spiral turns of the spiral conduit is 5-20.
Further, the pitch of the spiral conduit is constant or gradually reduced from the inlet end to the outlet end. The tapering enhances the responsiveness of the gas through the helical conduit. The one end that the pitch is big corresponds gas inlet, adapts to high velocity of flow gas, does not need too big pitch after gaseous stability, reduces the pitch and can improve the separation effect, and the stroke lengthening also can prolong the separation stroke, and the pitch reduces gradually and can slow down the gas velocity of flow for particulate matter or condensate separate more easily.
Further, the radius of the spiral conduit is constant or gradually increased from the inlet end to the outlet end. The radius gradually becomes larger, so that the gas flow rate is reduced, the particles or the condensate are easier to separate, and the adsorptivity is enhanced.
Furthermore, the screw pitch of the spiral conduit is 3-10 mm.
Further, the spiral radius of the spiral conduit is 3-20 mm.
The utility model has the advantages that:
the utility model discloses the appearance is small and exquisite, simple to operate, can experience external atmospheric pressure again when dampproofing, dirt-proof, and especially adapted uses in humidity, dust and sand environment, makes some baroceptor's range of application widen greatly.
The utility model discloses can make the gas that baroceptor pressure sensing end accepted through dampproofing, dustproof processing for the baroceptor measures more accurately. The utility model discloses a user is provided as the annex to the atmospheric pressure duct subassembly to satisfy user's dampproofing, dustproof demand. The pneumatic conduit assembly has the characteristics of compact structure, attractive appearance and convenience in use.
When the air pressure conduit assembly is used by a user, the air pressure conduit assembly is required to be connected into an air path system between an air pressure interface of the user and an air pressure sensor. In the moist, sand and dust environment, aqueous vapor, sand and dust and the like entering the user air pressure interface can be attached to the cavity of the spiral air pressure conduit under the action of gravity, and can not enter the air pressure sensor, so that the air pressure sensor can be normally used in the moist and sand and dust environment.
