Abstract
The utility model discloses a device used to detect the leakage of the sensor, which relates to the sensor detection technical field. The device consists of a plurality of cylindrical cylinder bodies, a sealing gasket, a flange plate, a pipe joint, a connecting plate, a cover plate, a tightening screw, a connecting screw, a sensor, an outlet valve, a gas bottle and a pressure gauge. The cylindrical cylinder body is fixed on the connecting plate by the connecting screw; the cylinder body is connected with a plurality of cylinder bodies by a two-way pipe joint to make the entered air pressure between the cylinders bodies equal when each cylindrical cylinder body is inflated. The utility model has simple structure, convenient operation, smart and convenient disassembly, strong sealability, anti-corrosion, high efficiency, largely improved producing efficiency and obviously reduced producing cost.
Description
Technical field
The utility model relate to the sensor detecting field, specifically be a kind of device whether liquid level sensor leaks under air pressure or hydraulic action that detects.
Background technology
Sensor is mainly used in to be measured and control system, the kind of sensor is a lot, as displacement transducer, strain gauge, load sensor, speed pickup, vibration transducer, pressure transducer, temperature sensor, humidity sensor and density sensor, liquid level sensor etc.Usually the liquid level sensor of aircraft series use also is to belong to one of tested transducer series, therefore, the sensor of Shi Yonging all must carry out strict sealing detection each time, quality and performance requirement are very high, traditional detection method is that a sensor is placed in the cylindrical tube that relies on the ring flange connection, add source of the gas ventilation pressurization and detect leakage, perhaps adopt gas, water detects frock and detects leakage, sealing is poor, owing to do not have threaded hole on the ring flange, the fixing often adopting process method of product, dismounting inconvenience, and the sensor of each auxiliary products all have separately can not be general the detection frock, can only be a sensor so whenever do one-time detection, also to change airtight pipe interface, and to spend a large amount of calculating for changing airtight pipe interface, can only detect 12 products at most by one day 8 hours.Work efficiency is extremely low, seriously takes time and effort.Can not adapt to problems such as product small serial production.
Summary of the invention
The utility model is at the problems referred to above of prior art, the technical scheme that solves provides the device that a kind of detecting sensor is leaked, this device by a plurality of column type cylindrical shells, packing washer, ring flange, pipe adapter, web joint, cover plate, housing screw, attachment screw, sensor, go out valve, gas cylinder, tensimeter and form.The column type cylindrical shell is fixed on the web joint by attachment screw, interconnects by the two siphunculus joint between cylindrical shell and a plurality of cylindrical shell, and when making each column type cylindrical shell inflation, the gaseous tension that enters each other equates.Described ring flange has groove, and O-ring seal is put into ring flange, and tested sensor inserts in the column type cylindrical shell, closely connects by the ring flange housing screw.Owing to adopted said apparatus, tested sensor is in the strict seal state, provides high-quality, the composite set that short run detects thereby can be the detecting sensor leakage.
The utility model beneficial effect: this apparatus structure is simple, easy to operate, lightly, convenient disassembly, sealing by force, corrosion-resistant again, high-level efficiency has solved the problem that above-mentioned detection multiple sensors exists, originally a direct labor can only finish 12 products in 1 day, a product surplus can finishing 50 in present one day, production efficiency improves greatly, and production cost obviously descends.
Description of drawings
Fig. 1: former ring flange synoptic diagram
Fig. 2: the ring flange synoptic diagram after the improvement
Fig. 3: the device synoptic diagram that detecting sensor is leaked
Wherein, 1 be column type cylindrical shell, 2 for ring flange, 10 for pipe adapter, 4 for packing washer, 5 for web joint, 6 for cover plate, 7 for housing screw, 8 for attachment screw, 12 for sensor, 11 for the valve of giving vent to anger, 13 for air intake valve, 14 tensimeters, 15 be gas cylinder.
Specific implementation method
Former as shown in Figure 1 ring flange is not with groove.Be illustrated in figure 2 as the ring flange 2 that improves back band groove, packing washer 4 is put into ring flange 2 grooves.Be illustrated in figure 3 as structural representation of the present utility model, the utility model is made up of a plurality of column type cylindrical shells 1, ring flange 2, packing washer 4, pipe adapter 10, web joint 5, cover plate 6, housing screw 7, attachment screw 8, sensor 12, the valve 11 of giving vent to anger, air intake valve 13, tensimeter 14, gas cylinder 15.Column type cylindrical shell 1 is fixed on the web joint 5 by attachment screw 8, described web joint 5 can prolong, interconnect by pipe adapter 10 between cylindrical shell 1 and the cylindrical shell 1, a plurality of column type cylindrical shells 1 can be set according to the length of web joint 5, and when making each column type cylindrical shell 1 inflation, the gaseous tension that enters each other equates.Described ring flange 2 has groove, packing washer 4 is put into ring flange 2, tested sensor 12 inserts in the column type cylindrical shell 1, closely connect by housing screw 7, tested sensor 12 is in the strict seal state, at this moment, close the valve 11 of giving vent to anger, open air intake valve 13, open gas cylinder 15, column type cylindrical shell 1 is inflated to certain pressure, close air intake valve 13, check whether sensor 12 lumen orifice have leakage, check after 30 minutes whether tensimeter 14 has decline, if pressure is constant, illustrate that sensor 12 bore seal are good.Otherwise, leakage has been described.
Close air intake valve 13, open the valve 11 of giving vent to anger, treat that gas has all been put after, dismantle 8 housing screws 7, take out sensor, airtight detection finishes.
The principle that watertight detects is the same with airtight detection, and difference only is that the water of putting into certain pressure in the frock tube makes sensor 12 be in hydraulic pressure, checks after 30 minutes whether hydraulic pressure descends.The frock inflated condition is after 30 minutes, and sensor 12 lumen orifice do not have leakage, proves that the sealing position of sensor 12 in the frock cavity do not have rosin joint or leakage, and the airtight detection of product is qualified.
