The utility model discloses a set up alone in the outside of changer at the air duct to be provided with waterproof ventilation valve at the air duct tip, can filter steam through waterproof ventilation valve like this, improve the degree of accuracy of throw -in type liquid level meter measuring.
Description
Technical field
The utility model relates to liquid level sensor device technical field, refers to a kind of called putting-into-type liquid level meter especially.
Background technology
The wireway that the upper end of existing called putting-into-type liquid level meter is connected with air is all that air communicates, such device in use just easily makes the steam in air enter into wireway, due to the water vapor condensation that temperature difference causes, through after a while, (snorkel only has usually less than 5mm will to form water column in snorkel, be easy to the water column forming more than 1m), and this liquid level gauge is exactly the pressure differential utilized between bottom pressure and air, by formulae discovery go out liquid level come, at this moment the water column in snorkel will have influence on the actual value that liquid level gauge is measured, such as, put into 50 meters of dark seabeds, the water column of 1 meter is produced bottom wireway, such measured value just becomes 49 meters, error reaches 2%, exceed the precision 1% of liquid level gauge, that device data is invalid.In addition, water column also can corrode circuit board, reduces insulating property, and time one length also can cause circuit to damage, thus causes the usability of called putting-into-type liquid level meter poor.
Therefore, must make improvements for above-mentioned defect.
Utility model content
The utility model proposes a kind of called putting-into-type liquid level meter, solve the problem of the usability difference of existing called putting-into-type liquid level meter.
The technical solution of the utility model is achieved in that
A kind of called putting-into-type liquid level meter, comprise the transmitter, cable and the probe that connect successively from top to bottom, wireway is provided with in described cable, described wireway one end is connected with described probe, described transmitter side is provided with the wireway matched with described wireway and exports, and described wireway outlet is also provided with the waterproof vent valve in mating connection with described wireway.
Further, described waterproof vent valve exports with described wireway and is threaded.
Further, connected by resistance to compression joint between described cable and probe.
Further, described strain relief clamp is connected on described transmitter.
Further, the mounting flange for fixing described transmitter is provided with below described transmitter.
Enforcement the beneficial effects of the utility model have:
The utility model by being separately set on transmitter at described wireway, and is provided with waterproof vent valve in wireway end, can filter steam like this by waterproof vent valve, improves the accuracy that called putting-into-type liquid level meter is measured.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the perspective view of a kind of called putting-into-type liquid level meter of the utility model embodiment.
Figure number and explanation thereof:
1, transmitter; 2, waterproof vent valve; 3, cable; 4, resistance to compression joint; 5, pop one's head in.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
With reference to Fig. 1, a kind of called putting-into-type liquid level meter that the utility model provides, comprise the transmitter 1, cable 3 and the probe 5 that connect successively from top to bottom, wireway is provided with in cable 3, wireway one end is connected with probe 5, transmitter 1 side is provided with the wireway matched with wireway and exports, and wireway outlet is also provided with the waterproof vent valve 2 in mating connection with wireway.Waterproof vent valve 2 main filtration steam, other impurity in certain air also together filter, and can improve the accuracy that called putting-into-type liquid level meter is measured like this.
Wireway outlet is provided with the first O-ring seal with waterproof vent valve 2 junction, can prevent liquid, impurity etc. from entering in cable 3 and/or transmitter 1 by the first O-ring seal, ensures the accuracy that transmitter 1 shows.Waterproof vent valve 2 exports with wireway and is threaded.Other connected mode can certainly be adopted to replace.
Connected by resistance to compression joint 4 between cable 3 and probe 5.The stability that cable 3 is connected with probe 5 can be ensured like this, ensure the accuracy detected.
Cable 3 is connected on transmitter 1.The second O-ring seal is provided with between cable 3 and transmitter 1, the sealing that cable 3 is connected with transmitter 1 can be ensured by the second O-ring seal, prevent liquid, impurity etc. from entering in cable 3 and/or transmitter 1 by cable 3 and transmitter 1 junction, ensure the accuracy that transmitter 1 shows.
Transmitter 1 is provided with the mounting flange for fixing transmitter 1 below.The installation of transmitter 1 is facilitated by mounting flange.
In sum, the utility model by being separately set in the outside of transmitter at wireway, and is provided with waterproof vent valve in wireway end, can filter steam like this by waterproof vent valve, improves the accuracy that called putting-into-type liquid level meter is measured.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
