An anti-leakage oil pipe filter

Abstract

The invention provides an oil-leakage-proof oil pipe filter. The oil-leakage-proof oil pipe filter comprises a valve body, an adjusting switch, a positioning sleeve, a spring and a filter screen, wherein one end of the valve body is a connection end which is connected with an oil pipe, and the other end of the valve body is a sealed end with a valve element; one end of the adjusting switch is connected with the valve element and the other end of the adjusting switch is provided with a radially convex positioning block; the positioning sleeve is movably connected to the valve body and sleeves the adjusting switch; a sliding groove is formed in a pipe body of the positioning sleeve; the positioning block of the adjusting switch is located in the positioning groove; the spring is arranged between the adjusting switch and the valve body; and the filter screen is arranged on the outer surface of the positioning sleeve and is used for filtering liquid entering and exiting from the valve body. The filter screen is arranged outside the positioning sleeve so that fuel oil entering and exiting from the oil pipe can be directly filtered, and furthermore, the safety of an oil pump or oil utilization equipment is guaranteed. The adjusting switch controlled by the spring can be used for automatically controlling the opening and closing of the oil pipe, the oil pipe is prevented from sprinkling of remaining fuel oil after leaving from the fuel oil, the wastes are reduced and potential safety hazards are eliminated.

Description

technical field [0001] The invention relates to the field of oil delivery, in particular to an oil pipe filter capable of sealing the pipeline after oil delivery to prevent oil leakage. Background technique [0002] At present, fuel oil needs to be purified and filtered before it is delivered and filled into the used fuel tank, so as to remove possible solid impurities in the fuel and prevent the delivery pump from getting stuck or polluting the used fuel tank. The equipment for realizing the above-mentioned filtering is generally installed on a fixed fuel supply equipment, which has been perfected in terms of fuel oil output and filtration. However, some portable refueling equipment is a mobile working method, which uses oil pipes to connect with the oil storage tank to be supplied, and the filter part is directly fixed to the mouth of the oil pipe with a filter screen, without sealing the oil in the pipe, or the switch is set in the pump body It is inconvenient to use, an...
