Description

This utility model relates to the technical field of oil outlet and oil removal of a transformer, and specifically relates to a new structure valve assembly with high-speed coupling.

Transformer oil has functions such as insulation, heat radiation, and arc extinguishing. Transformer oil must be periodically sampled at the oil outlet and tested for each insulation performance index of the transformer. There is a horizontal one-way valve that is often seen in the structure of the oil outlet of conventional transformers, and the sample tool corresponds to the one-way valve. The oil fluid enters the oil extraction device with the transformer. With the expansion of oil outlet functionality, some oil extraction devices include direct sensors or assemblies that perform monitoring and other operations after being installed directly at the oil outlet in the field, thus reducing the volume of the oil extraction device. Each shape is different. Some additional assemblies extend horizontally to the original oil outlet, making it inconvenient to remove oil.

As a result of the search, for example, the Chinese patent with publication number CN211259948U (Double insurance valve assembly of transformer oil outlet assembly type) includes the following technology. Specifically, it includes a fitting and a nut for mating with the self-sealing valve of the main transformer oil outlet of the substation, said fitting being a right-hand fitting, and located away from the oil outlet on the right-hand fitting. a flange is provided, said nut being a removable nut, one end of the removable nut being for engaging a threaded port attached to the one-way valve of the oil outlet; The end has a neck closure with a smaller diameter than the screw opening, and the neck closure is fitted into the right joint, and the diameter of the neck closure is smaller than the diameter of the flange. One end of the right joint remote from the oil discharge port is attached to the right continuation of a double valve, a left joint is attached to the left continuation of the double valve, and the double valve further includes a valve handle for opening and closing the valve. The above problem was solved by including.

However, the technical proposal of this utility model has the following technical problems. When using this valve assembly, the oil bottle must be attached to the outside of the self-sealing external valve through threads, and the oil bottle must be rotated multiple times when operated by the employee, which slows down the process. It is relatively complicated and seriously affects the oil extraction efficiency of employees, and when oil is extracted, the transformer oil is easy to spill around, polluting the environment.
For this purpose, we proposed a valve assembly with a new structure with a high-speed coupling.

The purpose of this utility model is that when using the valve assembly proposed in the above-mentioned background art, the oil bottle needs to be attached to the outside of the self-sealing external valve through the thread, and the operator does not have to operate it. The oil bottle needs to be rotated multiple times during the process, which makes the process complicated and seriously affects the efficiency of oil removal by workers.Moreover, when removing the oil, the transformer oil is likely to spill around, polluting the environment. In order to solve this problem, we provide a valve assembly with a new structure with a high-speed coupling.

In order to achieve the above purpose, this utility model provides the following technical proposal. The new structure valve assembly with high-speed coupling according to this technical proposal includes a valve body,
