Description
Technical field
The utility model relates to a kind of electrician tool, i.e. a kind of oil-filled mutual inductor sealing sample valve.
Background technology
Oil-filled mutual inductor needs regularly to extract insulating oil and carries out assay, and sampling process does not also wish to enter air.Therefore, the housing of oil-filled mutual inductor has special stopple coupon, and pipe is provided with gland bonnet, is provided with seal ball-valve in pipe, opens gland bonnet during sampling, then pushes seal ball-valve open, stretches into suction pipe and extracts insulating oil.Obviously, this way can not prevent entering of air completely, and can only require that sampler's action is fast, the used time is short, enters air less as far as possible, operation very difficult.
Summary of the invention
The purpose of this utility model is to provide a kind of oil sample that can gather in oil-filled mutual inductor, can not enter air, and structure is simple, easy to operate oil-filled mutual inductor sealing sample valve.
Above-mentioned purpose is realized by following technical scheme: develop a kind of oil-filled mutual inductor sealing sample valve, be characterized in: the main body of said sample valve is an intubate, the leading portion of intubate is provided with the external thread that can match with oil-filled mutual inductor stopple coupon internal thread, the middle part of intubate is the valve body that external diameter is greater than stopple coupon external diameter, the front end of valve body is provided with the elastic seal ring be enclosed within outside intubate, elastic seal ring external diameter is greater than stopple coupon external diameter, valve body back segment both sides are respectively provided with a lever-like handle radially extended, it is the connecting pipe of reduced diameter after valve body, connecting pipe back segment socket flexible pipe, connected sucking pipe after flexible pipe, suction pipe internal diameter and piston rod precision-fit.
One section of hexagonal nut is arranged with outside described valve body.
Described connecting pipe is provided with Capsule for subsequent use.
The beneficial effects of the utility model are: intubate insertion mutual inductor stopple coupon is sealed sampling nozzle by O-ring seal, and piston rod is twitched and formed negative pressure subsequently, then opening encapsulation ball valve oil pumping sampling, and at the end of oil pumping, intubate exits seal ball-valve closedown.The features such as whole process mutual inductor can not enter air, achieves totally-enclosed sampling, and has structure simply, easy to operate, are expected the essential product becoming industry.
Accompanying drawing explanation
Fig. 1 is a kind of front view of embodiment;
Fig. 2 is the working state schematic representation of this embodiment;
Fig. 3 is the idle storage configuration figure of this embodiment.
Visible in figure: intubate 1, external thread 2, elastic seal ring 3, hexagonal nut 4, valve body 5, handle 6, connecting pipe 7, flexible pipe 8, suction pipe 9, piston rod 10, housing 11, stopple coupon 12, seal ball-valve 13, Capsule 14.
Embodiment
A kind of embodiment is introduced below in conjunction with accompanying drawing:
Fig. 1 describes a kind of oil-filled mutual inductor sealing sample valve, and its main body is an intubate 1, and the leading portion of intubate 1 is comparatively thin, and diameter is less than the internal diameter of oil-filled mutual inductor stopple coupon 12, and is provided with one section of external thread 2 that can match with the internal thread of oil-filled mutual inductor stopple coupon 12.The middle part of intubate 1 is the valve body 5 that external diameter increases, and the external diameter of valve body 5 must be greater than the external diameter of stopple coupon 12 port, the flexible O-ring seal 3 in valve body 5 front end, and elastic seal ring 3 is enclosed within the outside of intubate 1, and external diameter is greater than stopple coupon 12 external diameter suitable for reading.Valve body 5 back segment both sides are respectively provided with a lever-like handle 6 perpendicular to valve body 5, valve body 5 is the connecting pipe 7 of reduced diameter below, connecting pipe 7 back segment socket flexible pipe 8, termination suction pipe 9 after flexible pipe 8, suction pipe 9 internal diameter and piston rod 10 precision-fit, its shape is similar to injector for medical purpose with function.One section of hexagonal nut is arranged with outside valve body 5.
During work as shown in Figure 2, intubate 1 is inserted in mutual inductor stopple coupon 12, rotate intubate 1 and its external thread 2 is engaged with the internal thread of stopple coupon 12, elastic seal ring 3 is oppressed the upper port of stopple coupon 12 and achieves sealing simultaneously.Suitably pull the piston rod 10 in suction pipe 9 simultaneously, sample valve channel lumen is made to be negative pressure state, intubate 1 is rotated further subsequently, elasticity of compression O-ring seal 13 and descending, and push seal ball-valve 13 open, accelerate pull suction pipe 9 inner piston rod 10, the insulating oil in oil-filled mutual inductor housing 11 can be gone out sample valve endoporus from the gap of seal ball-valve 13 and enter suction pipe 9 under vacuum suction simultaneously.Then, rotate backward valve body 5, intubate 1 is moved, seal ball-valve 13 is closed, then pulls out intubate 1, closes the upper cover of stopple coupon 12.Whole process mutual inductor can not enter air, achieves the sampling of totally-enclosed.Sample valve after using as shown in Figure 3, takes off flexible pipe and suction pipe censorship, Capsule 14 be enclosed within connecting pipe 7 suitable for reading can deposit for subsequent use.
