Fig. 1 is the external structure schematic diagram according to the utility model embodiment's sampling cock;
Fig. 2 is the internal structure schematic diagram according to the utility model embodiment's sampling cock;
Fig. 3 is that A-A is to sectional view.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technological scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model embodiment provides a kind of sampling cock for the electric power oil-filled electric equipment.Be elaborated below in conjunction with 1 to 3 pair of the utility model of accompanying drawing.
As shown in Figures 1 to 3, sampling cock comprises: valve body 1; Electric power oil-filled electric equipment connection mouth 5; Oil duct 6; The first sample tap 2 is arranged on valve body 1 sidewall; Stop valve 3 is used for the opening and closing of control the first sample tap 2, is arranged on valve body 1 sidewall with 2 one-tenth horizontal vertical angles of the first sample tap, that is to say, stop valve 3 and the first sample tap 2 are in one plane in the horizontal direction spent every 90 between the two; Branch's oil duct 13 is with oil duct 6 vertical settings; The sampling oil of the first sample tap 2 arrives 2 outlets of the first sample tap via oil duct 6, branch's oil duct 13, stop valve 3, bypass oil duct 12; The second sample tap 7 is arranged on valve body 1 lower end, is connected with electric power oil-filled electric equipment connection mouth 5 through oil duct 6.
As seen from the above description, by two sample taps of sampling cock, can carry out simultaneously two chemical analyses, than prior art, the utility model embodiment has improved the chemico-analytic efficient of light wood material, thereby has improved working efficiency.
