Abstract
The utility model discloses a kind of engine sump tank jettison gear, its structure is: the bottom of drain line joint is threaded with helmet, and drain line joint top light pipe section is placed in oil sump, by spot welding and purge cock joint chair fastening.Be processed with spring seat and respective springs in drain line joint, spool penetrates spring, is screw threads for fastening between spool and valve gap, and valve gap is provided with two drain oils.The face that in drain line joint, top contacts with helmet is provided with O-ring seal, and the surface of contact of spool and drain line joint is sealing surface.This device utilizes flowline connection to subsea to make one-way valve structures, the flow of oil extraction along with spool and drain line joint contact surfaces clearance distance and control, thus can not there is fuel injection event.Increase helmet in flowline connection to subsea outside, can dual sealing manner be played and avoid roof leaking accident to occur.The easy installation and removal of this device, does not use extracting tool just can carry out draining the oil operation simultaneously.
Description
Technical field
The utility model belongs to engine mechanical part, is specifically related to a kind of jettison gear of engine sump tank.
Background technique
The machine oil be stored in engine sump tank after a certain time of operation or because carry out detection experiment to oil product, need bleed off by motor.The method of draining the oil of current machine oil is, the oil bottom oil sump is blocked up bolt and pulls down, and machine oil is flowed in the container of access machine oil naturally.The defect that this kind of operating method exists is, causes machine oil splash in the moment of turning on the stifled bolt of oil, with it easy splash to operator, and can splash on other parts of motor.And because of the increase of number of times of changing oil, very easily cause the thread damage of the stifled bolt of oil and oil sump fuel outlet, and cause lubricating oil leakage thus and affect the fuel feeding and cooling effect that motor moistens.
The utility model proposes a kind of new jettison gear, but the problems referred to above are satisfactorily resolved.
Summary of the invention
The purpose of this utility model is, proposes a kind of oil sump jettison gear, under the prerequisite preventing oil spout, can ensure sealing and the reliability of purge cock.
: the lower part of drain line joint cylindrical is threaded with helmet that drain line joint upper part light pipe section is placed in oil sump for realizing this object technical pattern of the present utility model, by spot welding and purge cock joint chair fastening.Be processed with spring seat in drain line joint, spring is placed on spring seat, and spool penetrates spring, is screw threads for fastening between spool and valve gap, and valve gap is provided with two drain oils.The face that drain line joint inner tip contacts with helmet is provided with O-ring seal, and the surface of contact of spool and drain line joint is sealing surface.
Principle of the present utility model is, drain line joint interior arrangement is equivalent to an one-way valve, take helmet upwardly valve gap, because spool departs from drain line joint, the drain oil along spool and valve gap flows out and fuel injection event can not occur by the machine oil in oil sump.
The beneficial effect of feature of the present utility model and generation is, utilizes flowline connection to subsea to make one-way valve structures, the flow of oil extraction along with spool and drain line joint contact surfaces clearance distance and control, thus can not there is fuel injection event.Increase helmet in flowline connection to subsea outside, can dual sealing manner be played and avoid roof leaking accident to occur.The easy installation and removal of this device, does not use extracting tool just can carry out draining the oil operation simultaneously.
Accompanying drawing explanation
Shown accompanying drawing is Principles and methods sectional drawing of the present utility model.
Embodiment
Structure of the present utility model to be described further by embodiment below in conjunction with accompanying drawing.Engine sump tank jettison gear, comprises flowline connection to subsea, helmet, spring seat, spring, spool, valve bonnet seal cushion rubber, chain, rubber sheet gasket, screw, oil sump and purge cock joint chair etc.Its structure is: the lower part of drain line joint 1 cylindrical is threaded with helmet 2, and drain line joint upper part light pipe section is placed in oil sump 12, by spot welding and purge cock joint chair 13 fastening.Be processed with spring seat 3 in drain line joint, spring 4 is placed on spring seat, and spool 5 penetrates spring, is screw threads for fastening between spool and valve gap 6, and valve gap is provided with two drain oils 8.The face that drain line joint inner tip contacts with helmet is provided with O-ring seal 7, and the surface of contact of spool and drain line joint is sealing surface.
The bottom of helmet and the outer side surface of drain line joint are provided with screw 9, for being connected and fixed chain 10, lose when preventing helmet from taking.
Between purge cock joint chair in drain line joint top light pipe section and oil sump, and be equipped with rubber sheet gasket 11 between lower thread section and helmet, there is vibration damping and seal action.
The innovative point of the utility model structure is, is made " one-way cock " by flowline connection to subsea.Because spool bottom groove exports (being also groove) with drain line, processing grinding becomes good sealing surface, and two surface of contact fit tightly, so machine oil can not seepage by the pressure utilizing oil sump inner engine oil height to produce and the pressure of spring.If but promote valve gap from overcoming the pressure of spring in the other direction, now spool moves, machine oil just can be discharged smoothly.
Adopt Screw assembly between helmet and flowline connection to subsea, in helmet, be equipped with O type rubber ring simultaneously, its objective is just in case when oil dripping phenomenon does not sternly appear in flowline connection to subsea inner spool, helmet can play excellent sealing effect.
When motor needs to drain the oil, pull down helmet, to valve gap (upwards) applied thrust, and there will not be oil spout.Also can avoid the damage of the screw thread of oil sump oil discharge screw and oil sump fuel outlet, sealing effect reduces simultaneously.
