Problems solved by technology

However, when detecting the emission of evaporative pollutants from motor vehicle fuel, it is necessary to install a temperature sensor for real-time monitoring inside the fuel tank and closed container during the detection, and the fuel tank and closed container are mostly welded conversion joints directly on the vehicle. The methods of bonding sensors with oil-resistant adhesives all have high cost of preparation and installation before the test and long cycle time, improper welding methods are likely to cause fire and explosion safety accidents, the bonding method is easy to leak air, and installation and operation are inconvenient. Defects such as the use of the day
But the problem is that the welding and bonding method is easy to leak air, which will cause the detection failure, double the test cost and prolong the detection time, and affect the normal test and detection and measurement work. Therefore, it is urgent to abandon the existing fuel tanks and closed containers. The installation method with fuel welding and oil-resistant glue avoids defects such as potential safety hazards and insufficient tests

Embodiment 1

[0036] like figure 1 and figure 2 As shown, a misplaced adapter for installing a rod sensor on a pressure vessel includes a core rod 6 arranged in a test hole 11-1 of a pressure vessel 11, and the test hole 11-1 of the pressure vessel 11 There is a notch 11-2 on the hole wall, and the lower end of the core rod 6 is provided with a dislocation claw 6- that extends into the pressure vessel 11 from the notch 11-2 and closely fits the inner top wall of the pressure vessel 11 after rotation. 1. The core rod 6 is covered with a compression nut 7 for locking the position of the misaligned claw 6-1. The compression nut 7 is arranged above the pressure vessel 11, and the core rod 6 is provided with a There is a through hole for the rod sensor 1 to pass through and extend into the inside of the pressure vessel 11 .

[0037] In this embodiment, when the dislocation adapter is installed, the lower end of the core rod 6 is first inserted into the pressure vessel 11 from the test hole 11...

Embodiment 2

[0058] like image 3 and Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that the core rod 6 is connected with the pressure cap 2 through a core rod connecting rod 12, and the core rod connecting rod 12 is installed on the core rod 6 The upper end of the core rod connecting rod 12 is provided with a hole 12-1 communicating with the through hole on the core rod 6, and the outer wall of the core rod connecting rod 12 is provided with an external thread for connecting with the pressure cap 2.

[0059] In this embodiment, the quick connection between the core rod 6 and the pressure cap 2 can be realized by setting the core rod connecting rod 12. The core rod connecting rod 12 can be integrally formed on the upper end of the core rod 6, or can be Through the threaded connection between the external thread of the core rod connecting rod 12 and the internal thread of the through hole wall of the core rod 6, a hole 12-1 is set on the core rod connecting...

Abstract

The invention discloses a staggered-type adapter used for mounting a lever-type sensor on a pressure vessel. The staggered-type adapter comprises a core rod arranged in a testing hole in the pressure vessel; a notch is formed in the wall of the testing hole in the pressure vessel; a staggered pawl extended into the pressure vessel from the notch and tightly fitted with the inner top wall of the pressure vessel after rotation is arranged at the lower end of the core rod; a compression nut used for locking the position of the staggered pawl sleeves the core rod, and is arranged above the pressure vessel; a through hole, through which the lever-type sensor penetrates and extends into the pressure vessel, is formed in the core rod. The staggered-type adapter adopts a staggered-type mechanical connection manner, so as to realize effective connection between the staggered-type adapter and the pressure vessel; moreover, the preparation time for mounting of the staggered-type adapter is short; the mounting and the demounting are convenient; the staggered-type adapter can be utilized repeatedly; safety accidents caused by a welding manner can be avoided.

Description

technical field [0001] The invention belongs to the technical field of installation of a rod sensor on a pressure vessel, and in particular relates to a misplaced conversion joint for installing a rod sensor on a pressure vessel. Background technique [0002] Motor vehicle fuel evaporative pollutant emission limits are a mandatory indicator for evaluating vehicle performance. Among them, GB20998-2007 Motorcycle and Moped Fuel Evaporative Pollutant Emission Limits and Measurement Methods: It is to implement the "Environmental Protection Law of the People's Republic of China" and the "Law of the People's Republic of China on Air Pollution Prevention and Control" to control motorcycles and mopeds. Environmental pollution caused by vehicle fuel evaporation pollutants, environmental protection, and energy conservation are formulated in this standard. This standard stipulates the type approval, production consistency inspection requirements and judgment methods of motorcycle and ...
