Abstract
The utility model provides a current transformer oil drain valve with a control valve. One end of a connecting pipe is provided with the control valve. An outer end of the control valve is connected with a set screw. One end of the control valve, which is opposite with the set screw, is provided with a movable outer connection. One end of a connector is provided with a movable inner connection. Sealing rings are sleeved on a jointing pipe of the movable inner connection. Two sealing rings are provided and are parallelly sleeved on the jointing pipe. Because the control valve is provided on the connecting pipe, the amount of the discharged oil of an oil discharging valve can be controlled. Because the two sealing rings are sleeved on the jointing pipe of the connection end, total sealing can be obtained and oil leakage phenomenon can be prevented. The current transformer oil drain valve with the control valve is suitable for being mounted on the current transformer for draining the oil.
Description
Technical field
The utility model provides appliance field and is used for the current transformer fuel outlet valve that is provided with control valve that current transformer is drained the oil.
Background technology
The common 220kv current transformer of safeguarding, model is LCB7-220W1, belongs to outdoor type, wherein weight of oil reaches 365kg, because seasonal variations, summer temperature height, high humidity, the Water in oil amount very easily cause current transformer to make moist, in case greater than 10uL/L, just must be carried out oil processing.
Existing current transformer is drained the oil does not have valve on the parts, is not easy to grasp the amount of draining the oil when draining the oil, and the single track sealing ring that connects is difficult to realize sealing fully, therefore occurs oil leakage phenomenon easily.Influence result of use.
When existing fuel outlet valve is installed, generally all be under power-off condition, to carry out.Because transformer oil lower box part fuel outlet valve installation site is low excessively, drain oil unit is single, often controls badly, occurs sewing; And get oil sample one time, and need many people to work in coordination, to waste time and energy, the scene makes oil stain full of stains or spots again, and is very uneconomical.Because of active joint comes back rotation, the oil impregnate phenomenon appears in the joint.Moreover do not control the valve system of oil mass size, use very inconvenient.
Because the raising of power supply reliability comprises that the chemical examination of drawing oil sample waits operation to finish, so be badly in need of changing original oily mode of getting, designs and produces simple oil taking tool under situation about not having a power failure.
Summary of the invention
In order to overcome the shortcoming of existing current transformer fuel outlet valve, the utility model provides the current transformer that is provided with control valve fuel outlet valve.This fuel outlet valve is provided with the two seals circle by installation and control valve on tube connector with at link, solves the technical problem that current transformer is drained the oil.
The scheme that the utility model technical solution problem is adopted is: at tube connector one end control valve is installed, the control valve outer end is connected with jackscrew, and the relative end with jackscrew of control valve is provided with movable external; Be provided with in the activity and connect connecting first end, be set with sealing ring in the adapter that connects in the activity.Sealing ring is two, is sleeved in the adapter side by side.
Good effect owing to installation and control valve on tube connector, can make the fuel outlet valve amount of draining the oil controlled; Owing in the adapter of link, be set with two sealing rings, can reach sealing fully, prevent the generation of oil leakage phenomenon.Suitable being installed in of the utility model is used to the application of draining the oil on the current transformer.
Description of drawings
Fig. 1 is the utility model overall structure figure
Fig. 2 meets end structure figure in the utility model activity
Fig. 3 is the utility model activity external connection end structure chart
Among the figure, 1. tube connector, 2. control valve, 3. jackscrew, 4. movable external, 5. connector 6. connects in the activity, 7. sealing ring.
Embodiment
According to the figure, at tube connector 1 one ends control valve 2 is installed, the control valve outer end is connected with jackscrew 3, and the relative end with jackscrew of control valve is provided with movable external 4; Be provided with at connector 5 one ends and connect 6 in the activity, be set with sealing ring 7 in the adapter that connects in the activity.Sealing ring is two, is sleeved in the adapter side by side.
Use of the present utility model
In use, the fuel outlet of current transformer is opened, with jackscrew precession fuel outlet, open fuel outlet valve, oil is by connecing in tube connector, the activity and connector flows out, when reaching when getting oil mass, closed control valve, stop to get oil, and jackscrew is unloaded from the fuel outlet of current transformer, finish and once get oily operation.
Connector can connect flexible pipe, and the oil of being emitted is left in the oil vessel.
The jackscrew internal diameter is 8mm, be used for control and eject oil mass, other has screwed connection on active joint, move the size of controlling oil mass by switching through in the active joint, external and the joint that is connected petroleum pipeline of active joint is connected, got oil after, externally can unload together with petroleum pipeline in advance, be unlikely with the fuel outlet valve first half and together rotate, reach fully and separate.
At active joint cartridge control valve that the front adds, can effectively grasp the output size of oil.In addition, at the active joint oil impregnate, install the two seals cushion rubber additional, it is close to reach reliable envelope.The kit length overall is 250mm only.
Advantage of the present utility model
1, saves time and laborsaving, can increase work efficiency.
2, can control voluntarily and get oil mass, cut the waste.
3, nothing is sewed, and is pollution-free, reaches clean cleaning.
The utility model parts role
Jackscrew: eject the oil in the current transformer;
By-pass valve control: control oil mass;
Movable external: valve connects;
Connect in the activity: inside and outside connection;
Sealing ring: seal close effect;
Jointing: connect oil delivery hose.
