Abstract

The utility model discloses a special oil sampling valve for an oil-filled transformer, which comprises a hollow steel pipe and a copper ball valve which are connected in a threaded manner by the aid of a galvanized steel pipe. A rubber pipe with a sufficient length is arranged at the other end of the copper ball valve; sealing rings are arranged both between the hollow steel pipe and the galvanized steel pipe and between the galvanized steel pipe and the copper ball valve; internal threaded structures are arranged at both ends of the hollow steel pipe; external threaded structures are arranged at both ends of the galvanized steel pipe; and the galvanized steel pipe is arranged between the copper ball valve and the rubber pipe. After the special oil sampling valve is adopted, an injector is inserted into the rubber pipe for sealed sampling so that oil samples can not be exposed in air, real and effective data can be obtained, and accordingly the special oil sampling valve accurately judges whether potential faults exist in the transformer or not, is favorable for eliminating the faults at an early stage, and ensures safe and reliable running of a power grid.

Description

The oil-filled transformer special use valve that draws oil sample
Technical field:
The utility model relates to a kind of sampling fuel tap, particularly relates to a kind of special use that is used for transformer valve that draws oil sample, and is applicable to the oil-filled transformer that does not have the special-purpose sample valve of chromatogram in the power system transformer substation.
Background technology:
Based on filling type, this transformer all will carry out chromatography to its oil sample, to judge its running status after overhaul or before the spring inspection at the middle-size and small-size transformer of China.When carrying out the oil sample extraction, according to the sampling regulation, must under sealing state, carry out, but these transformers lack special-purpose chromatogram sample valve, oil sample is exposed in the air fully during sampling, does not accomplish the sealing sampling, does not meet rules and stipulates.Owing to do not sell special-purpose sample valve on the market, accomplish the sealing sampling, must carry out the transformation of device body to transformer, so, investment is big and cost is higher.
The utility model content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of special use of installing additional on oil-filled transformer lateral wall valve that draws oil sample is provided, solve the problem that runs in the real work.
The utility model is that the technical scheme that the technical solution problem is taked is:
A kind of oil-filled transformer special use valve that draws oil sample comprises hollow steel pipe and copper ball valve, and described hollow steel pipe and copper ball valve are threaded by coating steel pipe, and the copper ball valve other end is provided with the rubber tube of sufficient length.
Between described hollow steel pipe and the coating steel pipe and coating steel pipe and copper ball valve be provided with sealing ring.
The two ends of described hollow steel pipe are female thread structure.
Described coating steel pipe two ends are external thread structure.
Be provided with coating steel pipe between described copper ball valve and the rubber tube.
Good effect of the present utility model is:
1, in the process that draws oil sample of prior art, oil sample directly contacts with air, makes the chromatography result produce deviation, can't obtain authentic and valid data, can not whether exist the latency fault to make accurate judgement to transformer inside, be unfavorable for fault is eliminated in bud.And take special use of the present utility model to draw oil sample behind the valve in oil-filled transformer device body bottom, syringe is inserted rubber tube seal sampling, make oil sample not be exposed in the air, can obtain authentic and valid data, and then whether exist the latency fault to make accurate judgement to transformer inside, help fault is eliminated in bud, guarantee that power grid security moves reliably.
2, the utility model is simple in structure, sampling is convenient, and is safe in utilization, and accuracy is higher, and with low cost, be convenient to processing, market value is considerable.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
Referring to Fig. 1, a kind of oil-filled transformer special use valve that draws oil sample comprises hollow steel pipe 1 and copper ball valve 3, and described hollow steel pipe 1 and copper ball valve 3 are threaded by coating steel pipe 2, and copper ball valve 3 other ends are provided with the rubber tube 4 of sufficient length; Between described hollow steel pipe 1 and the coating steel pipe 2 and coating steel pipe 2 and copper ball valve 3 be provided with sealing ring; The two ends of described hollow steel pipe 1 are female thread structure; Described coating steel pipe 2 two ends are external thread structure; Be provided with coating steel pipe 5 between described copper ball valve 3 and the rubber tube 4.
In the actual mechanical process, this utility model product is installed at the place of draining the oil in oil-filled transformer device body bottom, the oil that just begins to flow out is bled off, get rid of the oil that impurity is arranged, then syringe being inserted rubber tube takes a sample, oil sample be not exposed in the air, seal sampling, make oil sample not be exposed in the air, can obtain authentic and valid data, and then whether exist the latency fault to make accurate judgement to transformer inside, and help fault is eliminated in bud, guarantee that power grid security moves reliably.
The utility model can be produced the tandem product of the different size that is complementary with it, different model, different size according to the size of fuel outlet valve on the equipment, and practicality is very strong.
