Description
Technical Field
The utility model relates to a main transformer relief valve of pumped storage power station, especially sectional type pressure relief valve lead oil and draw low tube device.
Background
A pressure relief valve (abbreviated as relief valve) is a pressure protection device for a transformer, and when there is a serious failure inside the transformer, oil is decomposed to generate a large amount of gas. Because the transformer is basically a closed object, the diameter of the connecting pipe communicated with the oil storage cabinet is smaller, and the pressure can not be effectively and rapidly reduced only by the connecting pipe communicated with the oil storage cabinet, the pressure in the oil tank is rapidly increased, and the oil tank of the transformer can be cracked. The relief valve will open in time, draining some transformer oil, reducing the pressure in the oil tank. After the pressure in the oil tank is reduced, the release valve is automatically closed to keep the oil tank sealed.
At present, a release valve used in a hydropower station is directly connected with an oil guide down-bent pipe bent by 90 degrees, and the oil guide down-bent pipe is a steel pipe and has relatively large weight, so the oil guide down-bent pipe needs to be connected with the release valve through riveting. When the release valve needs to be overhauled, the whole oil guiding down bent pipe needs to be detached from the release valve, and the disassembly and the assembly are very inconvenient. And present power station exists some relief valves and is located the open air condition, and it directly exposes in external environment, and severe environment such as rainwater can lead to relief valve's life-span accelerated loss to cause its life to reduce, the phase change has improved its use cost.
Therefore, the release valve used in the current hydropower station has the problems of inconvenient maintenance of the directly riveted oil guide down bent pipe and short service life without protective measures.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a sectional type pressure relief valve leads oil and draws low tube device. The utility model has the advantages of convenient maintenance and longer service life.
The technical scheme of the utility model: the sectional type pressure relief valve oil guiding and discharging pipe device comprises a transformer and a relief valve which is arranged above a wall body and connected with the transformer; a rain cover is arranged above the release valve, a cover door capable of rotating up and down is arranged on one side of the rain cover away from the wall body, and a pipe leading groove is formed in the bottom of the cover door; the release valve is connected with the corrugated pipe through a flange plate, one end of the corrugated pipe is located in the rain cover through the pipe guiding groove, and the other end of the corrugated pipe is connected with the vertical pipe guiding through the flange plate.
In the segmented pressure release valve oil guiding and discharging pipe device, the top of the cover door is rotatably connected with the rain cover through a plurality of hinges; the cover door is provided with a handle.
In the segmented pressure relief valve oil guiding and discharging pipe device, a mounting base is arranged on the side surface of the wall body corresponding to the vertical guiding and discharging pipe; one side of the mounting base corresponding to the vertical down-leading pipe is provided with a hydraulic telescopic pipe which is horizontally arranged; a pipeline hoop is arranged at one end of the hydraulic telescopic pipe close to the vertical down-leading pipe; the pipeline hoop is arranged on the vertical down-leading pipe.
Compared with the prior art, the utility model discloses an add and establish the bellows, connect relief valve and vertical tube of drawing down through the ring flange respectively by crooked bellows both ends, it is more convenient that the dismouting is connected to the ring flange connection is compared original riveting to staff's manpower and time when can sparingly overhaul improve maintenance efficiency. Moreover, the utility model discloses an add on the release valve and establish rain-proof cover, rain-proof cover is effectual to play the effect that hides wind and rain for the release valve to prevent that the release valve from leading to acceleration strain because of adverse circumstances, the life-span of release valve is longer relatively.
Therefore, the utility model has the advantages of convenient maintenance and longer service life.
Further, the utility model discloses an add on rain-proof cover and establish rotatable cover door, only need upwards open the cover door when needs overhaul and just can overhaul the release valve, cover door can be fine again when need not to overhaul plays the effect of sheltering from.
Through set up the installation base of taking hydraulic telescoping pipe on the wall body, adjust the distance between vertical downlead and the wall body through hydraulic telescoping pipe, can adjust the interval according to the environment of difference again when playing fixedly, the suitability is wider.
