Description
Technical field
The utility model relates to high pressure oil immersion mutual inductor, specifically a kind of high pressure oil immersion mutual inductor Oil-filling and drainage valve.
Background technique
Because need crude oil sample analysis inspection be carried out when mutual inductor product is checked and accepted at the scene; In addition, when whether the running state need understanding high pressure oil immersion mutual inductor is good, within the setting period, need to carry out Insulation monitoring to product.Check whether its characteristic gas has significant change by chromatograph after extraction oil sample, can find whether its major insulation aspect has problems.And mutual inductor product belongs to few oily equipment, each institute draws oil sample to test needed for reality and is advisable, can not be too many, otherwise the waste causing transformer oil unnecessary; Meanwhile, the oil impregnate produced when drawing oil sample also can to environment.
Model utility content
For exist in prior art draw oil sample time cause transformer oil to waste and the oil impregnate that produces to the problem of environment, the purpose of this utility model is to provide a kind of high pressure oil immersion mutual inductor Oil-filling and drainage valve.
The purpose of this utility model is achieved through the following technical solutions:
The present invention includes valve body, valve gap, spool and spheroid, wherein one end of valve body is arranged in the base of mutual inductor main body of described high pressure oil immersion mutual inductor, and the other end is connected with described valve bonnet seal; Two spools are provided with in the inner chamber of described valve body, moveable spheroid is equipped with in space between described two spools, be the sphere matched with spheroid along getting spool that oily direction is positioned at outside towards the end face of described spheroid one end, described two spools all have oil drain canal.
Wherein: described two spools are the first spool and the second spool, are threadedly connected in the inner chamber of described valve body respectively, in the space of described spheroid between the first spool and the second spool; Described second spool and the first spool are arranged from inside to outside along getting oily direction, and this first spool is sphere towards the end face of described spheroid one end, and the oil drain canal on described first spool and the second spool is arranged all vertically; Described first spool and the second spool are arranged in the same way vertically in the inner chamber of valve body, and this first spool and the second spool are equipped with outside thread, are threaded respectively with the internal thread in the inner chamber of described valve body; The longitudinal center line conllinear of oil drain canal, valve body and valve gap on the oil drain canal on described first spool, the first spool, the second spool, the second spool; Seal ring is provided with between the other end of described valve body and valve gap.
Advantage of the present utility model and good effect are:
1. the utility model is provided with rational oil drain canal at first and second center spool, and the first spool is the sphere matched with spheroid towards the end face of spheroid, the effect of oil pressure is added when drawing oil sample, high pressure oil immersion mutual inductor is sealed still very reliable, there will not be leakage of oil problem; And, by controlling thimble quantity that positioning control draws oil sample, again because Oil-filling and drainage valve and the good fit of sample collector do not exist Seepage, the pollution of environment can also be avoided.
2. the utility model structure is simple, easy to use, and operation is reliable.
Accompanying drawing explanation
Fig. 1 is internal structure schematic diagram of the present utility model;
Wherein: 1 is valve body, 2 is seal ring, and 3 is valve gap, and 4 is the first spool, and 5 is spheroid, and 6 is base of mutual inductor main body, and 7 is the second spool, and 8 is oil drain canal, and 9 is space.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the utility model comprises valve body 1, valve gap 3, first spool 4, spheroid 5 and the second spool 7, wherein the inner chamber of valve body 1 is provided with internal thread, one end of this valve body 1 is welded in the base of mutual inductor main body 6 of high pressure oil immersion mutual inductor, the other end is threaded with valve gap 3, and seal ring 2 is provided with between the other end and valve gap 3 of valve body 1, seal.
The inner chamber of valve body 1 is connected with high pressure oil immersion mutual inductor inside, is provided with two spools in the inner chamber of valve body 1, the first spool 4 and the second spool 7.First spool 4 and the second spool 7 are equipped with screw thread, are connected respectively with the internal thread in the inner chamber of valve body 1; First spool 4 and the second spool 7 arrange, are positioned at the inner chamber two ends of valve body 1 vertically in the same way in the inner chamber of valve body 1, along getting the outside that oily direction first spool 4 is positioned at the second spool 7.Moveable spheroid 5 (spheroid 5 of the present embodiment is steel ball) is equipped with in space 9 between the first spool 4 and the second spool 7, first spool 4 is the sphere matched with spheroid 5 towards the end face of spheroid 5 one end, and the sphere namely on the first spool 4 is inner towards high pressure oil immersion mutual inductor.First spool 4 and the second spool 7 all have the longitudinal center line conllinear of oil drain canal 8, valve body 1 and the valve gap 3 on oil drain canal 8, second spool 7, second spool 7 on oil drain canal 8, first spool 4, first spool 4 arranged vertically.
Working principle of the present utility model is:
When drawing oil sample, when taking off valve gap 3 and oil thief is not also received on Oil-filling and drainage valve, due to sphere and spheroid 5 Proper Match of first spool 4 one end, add the effect of oil pressure, make high pressure oil immersion mutual inductor sealing now still very reliable, there will not be leakage of oil problem.
When spheroid 5 to be backed down the sphere of the first spool 4 by the thimble of sample collector, transformer oil just can enter in sample collector, and can to realize drawing oil sample the control of quantity by controlling thimble position; Again because Oil-filling and drainage valve and the good fit of sample collector do not exist Seepage, avoid the pollution of environment.
