Description

Improved sealing and releasing oil filling valve

Technical Field

The utility model relates to the technical field of sealing and placing oil filling valves, in particular to an enhanced sealing and placing oil filling valve.

Background

The sealing and placing oil filling valve is specially used for filling oil, discharging oil, sealing and extracting oil samples of power transformers, oil transformers and other equipment. The existing oil valve is in sealed connection with conical surface metal hard connection, and when the existing oil valve is fastened by improper force, a sealing inclined surface is easy to scratch, so that leakage accidents are caused, the service life is very short, the existing oil valve is repeatedly abandoned due to unsmooth smoothness of the conical surface body, and the maintenance cost is increased.

When oiling again, lift off the closing cap, oil can spray and go out simultaneously, cause environmental pollution, when monitoring equipment operates, if the inside grease condition of regular judgement, need extract the oil appearance many times, lift off the closing cap this moment and can go out because of the oil sprays many times, lead to polluting the environmental area diffusion, meanwhile, hard connection existence's hard wound (only one seal), once sealed not tight, then the oil can continue the seepage, cause environmental destruction very big, can cause equipment paralysis if on-the-spot can not in time discover or the oil is not in time mended, thereby lead to large-area power failure.

Before the oil valve material is the material of ordinary ironware Q235, easy oxidation rust, change waste time and energy.

Detailed Description

In the description of the present utility model, it should be understood that the terms "center," "lateral," "upper," "lower," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like indicate or are based on the orientation or positional relationship shown in the drawings, merely to facilitate description of the utility model and simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the utility model. Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present utility model, unless otherwise indicated, the meaning of "a plurality" is two or more. In addition, the term "include" and any variations thereof are intended to cover a non-exclusive inclusion.

The present utility model will be described in further detail with reference to the accompanying drawings.

The improved sealing and placing oil taking and injecting valve comprises a sealing nut 1, an oil taking sampler 2, a sliding oil pipe 3, a main body valve seat 4, a sealing flat gasket 5, a sealing ball 6, a limiting sleeve 7, a pressure spring 8 and a cock fixing seat 9;

the sealing nut 1 has been cup jointed to main part disk seat 4 upside, the inside movable sliding oil pipe 3 of upper and lower movable has been cup jointed in main part disk seat 4 upper portion activity, sliding oil pipe 3 top activity has cup jointed oil sampler 2, oil sampler 2 upper portion forms needle glib 14, sliding oil pipe 3 downside is equipped with cup joints the sealed flat pad 5 of fixing on main part disk seat 4 middle part circumference inner wall, cup joint and be fixed with cock fixing base 9 on main part disk seat 4 bottom circumference inner wall, through spacing sleeve 7 fixed connection between sealed flat pad 5 and cock fixing base 9, spacing sleeve 7 inboard activity is provided with sealed ball 6, sealed ball 6 upside is inconsistent with sliding oil pipe 3's bottom, and be connected through pressure spring 8 between downside and the cock fixing base 9.

It should be noted that the connection between the sealing nut 1 and the main body valve seat 4 is sealed by an O-ring 10. The oil sampler 2 and the sliding oil pipe 3 are sealed through a second O-shaped ring 11. The sliding oil pipe 3 and the main body valve seat 4 are sealed by an O-shaped ring III 12. And a sealing ring 13 is fixedly sleeved on the circumferential inner wall of the bottom end of the main body valve seat 4.

The embodiment is implemented in specific manner: when the sliding oil pipe 3 moves towards the sealing ball 6, the sealing ball 6 is separated from the sealing flat gasket 5, an oil duct is opened, the oil speed and the flow can be controlled according to the separation gap, the oil is injected at the moment, and the limiting sleeve 7 carries out limiting control on the sealing flat gasket 5 at the moment due to the fact that the oil pressure is too high during oil injection, so that displacement caused by the oil pressure is avoided.

When the oil sample is taken, the sliding oil pipe 3 is rotated, and the oil product can automatically flow out from the needle type oil nozzle 14, so that the oil quality is judged. After oiling is completed, the sliding oil pipe 3 moves upwards to seal, the sealing ball 6 returns, the oil way is closed, and under the action of the pressure spring 8, the sealing can be kept for a long time, and the O-shaped ring I10, the O-shaped ring II 1, the O-shaped ring III 12 and the sealing flat gasket 5 are sealed in quadruple mode.
