Abstract
The utility model relates to a dual-purpose valve which is arranged at the bottom of the oil tank of an oil-filled transformer for sampling oil or discharging oil. The oil discharging valve and the oil sampling valve of the utility model are connected together into integration, and particularly, an oil sampling valve is arranged at the lower part of the valve body of the oil discharging valve, so the utility model has two functions. The utility model is mainly composed of a valve body, a gland, a handwheel, a screw rod, a valve plate, a sealing ring, an oil inlet, an oil sampling valve, an oil discharging outlet and a baffle. The valve is produced and installed easily and can save production cost.
Description
The utility model relates to a kind of Dual-purpose valve, and it is installed in the oil tank for oil immersion type transformer bottom, is used to draw oil sample or drain the oil.
At present, the oil tank for oil immersion type transformer bottom all is equipped with Fuel Bleed Valve respectively and the valve that draws oil sample.Like this, its fuel tank bottom must be opened two holes and respectively be pacified a valve again, not only manufacturing expenses man-hours, also increases the annex cost simultaneously
For overcoming the above-mentioned defective of prior art, the utility model aims to provide a kind of Dual-purpose valve, and it is installed in the oil tank for oil immersion type transformer bottom, is used to draw oil sample or drain the oil.
For achieving the above object, the utility model is integrated the Fuel Bleed Valve and the valve that draws oil sample exactly, and the concrete practice is exactly to set up the valve that draws oil sample in the valve cast bottom of Fuel Bleed Valve, and it is dual-purpose to reach one.
Owing to take above-mentioned technical solution, the utlity model has the one double-purpose functional, not only make simply, easy for installation, also save manufacture cost, be suitable for and promote the use of.
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing, elaborate specific embodiment of the utility model and working principle thereof:
Referring to accompanying drawing as can be known, the utility model mainly is made of valve cast 1, gland 2, handwheel 5, screw mandrel 7, valve plate 9, seal ring 10, filler opening 11, the valve 12 that draws oil sample, plate washer 14 and fuel outlet 15, is provided with filler opening 11 on valve cast 1, valve 12 and fuel outlet 15 draw oil sample.Gland 2 is installed in the top of valve cast 1 through screw 3, and the center hole on the screw mandrel 7 string overpressure cap 2 is also realized its sealings through trim ring 4 and glue ring 8.Handwheel 5 is installed in the upper end of screw mandrel 7 through nut 6, the screw portion kissing of establishing in the screw thread portion of screw mandrel 7 and the valve cast 1, and valve plate 9 and seal ring 10 are equipped with in the lower end of screw mandrel 7.Plate washer 14 is installed in an end face of valve cast 1 through screw 13, to realize the sealing to fuel outlet 15.
Working principle and using method: the utility model is installed in the fuel tank bottom of transformer, makes the oil outlet on the fuel tank relative with filler opening 11.At ordinary times, valve plate 9 is in extreme lower position in valve cast 1, and the seal ring 10 below the valve plate 9 is with the stifled tight envelope of passage of 15 of filler opening 11 and fuel outlets.Valve 12 is located at the bottom of valve cast 1 because draw oil sample, and can use it at any time and draw oil sample.When desiring to drain the oil, plate washer 14 is unloaded, fuel outlet 15 joins with drain line, rotates handwheel 5, and screw mandrel 7 just drives on valve plate 9 and the seal ring 10 and moves, and the center-aisle of filler opening 11 and fuel outlet 15 is opened, and the oil in the oil tank of transformer can be emitted.
