Closed-circuit sampler special for aviation oil quality detection

Abstract

The invention discloses a closed-circuit sampler special for aviation oil quality detection. The closed-circuit sampler comprises a base provided with an aviation oil inlet, a glass cylinder, a sealing cover component hinged to the upper end of the glass cylinder, a ball valve body detachably connected to the bottom of the base, a handle component detachably connected to one side of the base, anda liquid taking component which is arranged on the other side of the base and communicates with the interior of the glass cylinder, wherein a ball valve core in the ball valve body communicates with the aviation oil inlet of the base; a vertical valve core through hole is arranged in the center of the ball valve core; a filter baffle plate is detachably arranged in the valve core through hole; thehandle component comprises a rotating shaft and a handle connected to the rotating shaft; and the rotating shaft is coaxially and detachably connected to a valve rod below the base. According to theclosed-circuit sampler, the integral detachable structure design is adopted, the ball valve body can be conveniently disassembled, the ball valve core and related parts can be conveniently maintained,overhauled and replaced, and a situation that a chemical water measurer falls into the closed-circuit sampler and then enters an oil pipeline system to cause blockage of an oil product pipeline system or pollution of an oil product is avoided.

Description

technical field [0001] The invention relates to the technical field of aviation fuel detection, in particular to a closed-circuit sampler specially used for aviation fuel quality detection. Background technique [0002] Aircraft refueling vehicle is a special vehicle specially used for refueling aircraft at the airport. When adding aviation fuel to the aircraft fuel tank, it is necessary to sample and test the aviation fuel, and the aviation fuel that has passed the test can be refueled. [0003] The existing closed-circuit sampler comprises parts such as a glass cylinder, a sample lifting cover, a sample detection port, an oil inlet and outlet valve seat, and a ball valve. When it is necessary to detect the quality of the oil at the inlet and outlet of the filter, it is necessary to switch the inlet and outlet control ball valves. The oil enters such as a closed-circuit sampler through the pipeline. Determination, after the detection is completed, open the ball valve at t...

Problems solved by technology

[0005] 1. Because the chemical water measuring device is easy to fall off and fall into the closed-circuit sampler, the chemical water measuring device enters the ball valve spool and flows into the oil pipeline, which affects the sampling test work of the closed-circuit sampler, and in actual operation, Operators often open the sample cover to inhale the oil from above, which is more likely to cause the above situation;

[0006] 2. The integrated structure of the base and the ball valve core is inconvenient to replace the ball valve core and other related parts during actual use. Once the internal ball valve core is damaged, the matching ball valve core must be replaced before it can continue to be used. Maintenance costs Higher, it will delay the maintenance time and affect the normal detection of aviation fuel
