Description
Technical field
The utility model relates to a kind of detection meter case, belongs to metering and process and detects the control field.
Background technology
In activities such as industrial processes control, metering, need to use corresponding instrument that physical quantitys such as temperature, pressure, flow and thing position are detected, as thermometer, tensimeter, flowmeter, level meter etc.These instrument all have a shell, and various electronic units, mechanical parts, sensor etc. are installed in the housing, and the material of shell can be plastics, also can be metal.The effect of shell is that device, the parts to its inside are protected, and prevents the erosion of outside bump, corrosive gas or liquid, guarantees that instrument can work steady in a long-term.Meter case must have good sealing property, reliable degree of protection, and particularly when outdoor mounted is used, or under the environment of gas or liquid that is corrosive, the positiver sealing of instrument is even more important.
Meter case is made of main casing and cap usually, and the shell that has is a up-down structure, is cap (loam cake) above, is main casing below; Have plenty of left and right sides structure, the left and right sides is a cap, and the centre is a main casing.No matter be any structure, all need the introducing of external cable, be used for instrument power supply, outwards transmit the detection limit signal.Meter housing is provided with the cable intake and cable entry is installed, and cable entry is generally water joint, and cable enters gauge internal by water joint.Water joint normally is installed in the side of instrument main casing in the mode of level, cable enters in the meter housing with the direction of level, should screw the nut of water joint after cable is introduced, rainwater flow in the instrument by cable when being subjected to drenching with rain when preventing outdoor mounted.Ultrasonic material level meter as shown in Figure 1, its cable enters in the meter housing by the water joint horizontal mode of side, and what the watchcase bottom connected is ultrasonic probe.
In actual applications, the instrument of outdoor mounted rainwater often occurs and enters into the situation that causes instrument to be corroded and to damage in the instrument by water joint not because there has been the cable waterproof joint just can guarantee that rainwater does not enter in the housing.Reason has two, at first is the positional structure of water joint and the reason of used material.Water joint is made of adapter body, back nut and inner plastics convergent-divergent head and rubber seal.Cable screws nut after introducing, and inner plastics convergent-divergent head can make rubber seal push down cable, and the space around eliminating forms sealing.But because inner plastics convergent-divergent head and rubber seal have certain elasticity, through long retroaction, nut can produce loosening gradually, the slit can occur around the cable, owing to be the horizontal direction lead-in cable, rainwater just may infiltrate gauge internal when being subjected to drenching with rain.If former two is that the installation and maintenance personnel of instrument fail to screw water joint when installing or safeguarding therefore, then can cause the intrusion of rainwater inevitably.
The utility model content
The purpose of this utility model is exactly to design a kind of shell of new construction, prevents that effectively instrument rainwater when outdoor mounted is subjected to drenching with rain from flowing into the generation of gauge internal situation by the cable intake.
The utility model is a up-down structure, is made of main casing and loam cake, and the main casing bottom is provided with coupling arrangement and is used for being connected with sensor or other equipment.The main casing upper end is round, is provided with external thread, is used for being connected with loam cake, and the loam cake inboard is provided with internal thread.Feature of the present utility model is: the inside in the round upper end of main casing forms a platform, on platform, be provided with the cable intake, the housing side that is in this platform below is for the circular upper side of its top, be inside indent form, to realize the cable intake structure of its top, make cable entry (as water joint) can be installed in the bottom of the round upper end of housing in mode from bottom to top, guarantee that external cable can enter enclosure interior from bottom to top, for suitable space is reserved in the introducing of cable.Because cable is the enclosure interior that enters from bottom to top, housing rainwater when being subjected to drenching with rain just can not penetrate into or flow in the housing by cable inlet.
Guaranteed water-resistant performance reliable of housing from structural design.
