Abstract
The utility model provides a take transformer insulating oil sampler of end cap, including the barrel in its inner zone chamber, set up the sample mouth of pipe at the cavity front end, set up the piston rod in the cavity, the piston rod outer end passes the cavity rear end and outwards extends, is equipped with the end cap on its characterized in that sample mouth of pipe, and this end cap includes the upset seal cover of outer end and the inner plug post. Can conveniently insert the sealed stopper post in the sample mouth of pipe, accomplish the shutoff of once taking a sample the orificial, the upset of rethread upset seal cover makes its parcel sample mouth of pipe outer wall, accomplishes the orificial secondary shutoff of taking a sample, can effectively avoid the insulating oil in the cavity to leak, can effectively avoid insulating oil to be polluted by external filth again, ensures that the sample mouth of pipe has higher sealing performance, can also avoid the damage sample mouth of pipe simultaneously.
Description
Technical Field
The utility model relates to a transformer insulating oil sampler, especially a transformer insulating oil sampler of taking end cap belongs to detection apparatus manufacturing and designing technical field.
Background
When the gas content of the transformer insulating oil is detected, a special oil taking needle tube is required to be used for extracting the insulating oil, and after the insulating oil is extracted, the end of the needle tube is sealed by a plug, so that the insulating oil is ensured not to be polluted, and meanwhile, the gas in the insulating oil is prevented from leaking or air enters to influence the accurate detection of the actual gas content in the transformer insulating oil. The existing plug is only a simple sleeve cap, sealing performance is difficult to guarantee easily when sampling is conducted at high frequency, the existing plug drops off when a sampling opening is plugged, and finally an oil sample is polluted before an experiment to influence detection effect. There is therefore a need for improvements in the prior art.
Disclosure of Invention
There is the sample connection shutoff bad for solving current transformer insulating oil tolerance detects with the sampler, leads to the oil appearance to be contaminated before the experiment and influences the testing effect scheduling problem, the utility model provides a take transformer insulating oil sampler of end cap.
The utility model discloses a following technical scheme accomplishes: the utility model provides a take transformer insulating oil sampler of end cap, includes the barrel in its inner zone chamber, sets up the sample mouth of pipe at the cavity front end, sets up the piston rod in the cavity, and the piston rod outer end passes the cavity rear end and outwards extends, is equipped with the end cap on its characterized in that sample mouth of pipe, and this end cap includes the upset seal cover of outer end and the inner sealing plug post to in inserting the sampling pipe post with the sealing plug post, turn over the upset seal cover downwards again, make it wrap the sample mouth of pipe and accomplish the orificial shutoff of taking a sample.
The sealing plug column is arranged to be a cylinder, the outer diameter of the cylinder is matched with the inner diameter of the sampling pipe orifice, so that the sealing plug column can be conveniently inserted into the sampling pipe orifice, one-time plugging of the sampling pipe orifice is completed, and the insulating oil in the cavity is prevented from being polluted.
And the top of the sealing plug column is provided with a circular arc-shaped sealing cap so as to plug the sampling pipe orifice through the circular arc-shaped sealing cap.
The turnover sealing sleeve is designed into a cylinder shape, an opening is formed in the outer end of the turnover sealing sleeve, the inner end of the turnover sealing sleeve is connected with the outer edge of the arc-shaped sealing cap, the inner diameter of the turnover sealing sleeve is matched with the outer diameter of the sampling pipe opening, and the turnover sealing sleeve is designed into an elastic soft sleeve so as to be capable of wrapping the outer wall of the sampling pipe opening after being turned over, secondary plugging of the sampling pipe opening is completed, and plugging performance is further enhanced.
The utility model has the advantages of it is following and effect: adopt above-mentioned scheme, can conveniently insert the sealing plug post in the sample mouth of pipe, accomplish the shutoff of orificial one time of taking a sample, the upset of rethread upset seal cover makes it wrap the orificial outer wall of taking a sample, accomplishes the orificial secondary shutoff of taking a sample, can effectively avoid the insulating oil in the cavity to leak, can effectively avoid insulating oil to be polluted by external filth again, ensure that the mouth of pipe of taking a sample has higher sealing performance, can also avoid damaging the sample mouth of pipe simultaneously.
Drawings
FIG. 1 is a schematic view of the present invention;
fig. 2 is a view showing the structure of the plug of fig. 1.
The present invention will be further described with reference to the accompanying drawings.
The utility model provides a take transformer insulating oil sampler of end cap, including barrel 1 of its inner zone chamber 3, set up the sample mouth of pipe 4 at the 3 front ends of cavity, set up piston rod 2 in cavity 3, the 2 outer ends of piston rod pass 3 rear ends of cavity and outwards extend, wherein: a plug is arranged on the sampling pipe orifice 4 and comprises an overturning sealing sleeve 7 at the outer end and a sealing plug column 5 at the inner end; the sealing plug 5 is a cylinder, the outer diameter of the cylinder is adapted to the inner diameter of the sampling pipe orifice 4, so that the sealing plug 5 can be conveniently inserted into the sampling pipe orifice 4 to complete one-time plugging of the sampling pipe orifice, and the insulating oil in the cavity is prevented from being polluted; the top of the sealing plug 5 is provided with an arc-shaped sealing cap 6 so as to seal the sampling pipe orifice 4 through the arc-shaped sealing cap 6; the turnover sealing sleeve 7 is cylindrical, an opening is formed in the outer end of the turnover sealing sleeve, the inner end of the turnover sealing sleeve is connected with the outer edge of the arc-shaped sealing cap 6, the inner diameter of the turnover sealing sleeve 7 is matched with the outer diameter of the sampling pipe orifice 4, and the turnover sealing sleeve 7 is an elastic soft sleeve so as to wrap the outer wall of the sampling pipe orifice 4 after being turned over, secondary plugging of the sampling pipe orifice is completed, and plugging performance is further enhanced.
During the action, the sealing plug 5 is inserted into the sampling pipe orifice 4, and the turnover sealing sleeve 7 is turned downwards to cover the sampling pipe orifice 4 to complete the plugging of the sampling pipe orifice 4, so that the taken transformer insulating oil 8 does not leak and is not polluted.
