Abstract
The utility model discloses a fuel outlet ball valve for a transformer, which is characterized in that at least two sealing rings are arranged on a valve stem; a movable handle is arranged on a hand wheel; a positioning sheet is arranged in a valve body, and is connected with the valve stem; a cover plate is arranged on the valve body, and a convex block is arranged on the positioning sheet; a notch is arranged on the cover plate. The utility model has the advantages of high oil resistance, strong corrosion resistance, high temperature and low temperature (from + 260 DEG C to -250 DEG C) resistance, long service life, convenient operation, quick oil outlet performance, environment protection, etc., and is an ideal substitute for a fuel outlet valve for a transformer.
Description
The utility model belongs to the annex of transformer, specifically is used for the ball valve of draining the oil of transformer.
The valve that is used to into, drains the oil on the existing transformer seals common gate valve or the single stop valve of paying of paying that seals mostly firmly, these valves are easy to generate leakage in the transformer using process, directly influence the transformer technology quality requirement, cause working life short, and because leakage of oil has caused environmental pollution.
The purpose of this utility model is a kind of operation of being convenient to, the antileakaging transformer ball valve of draining the oil.
The technical solution of the utility model is achieved in that the transformer ball valve of draining the oil, it mainly comprises valve body, be contained in the handwheel on the valve body, be contained in the valve seat in the valve body, valve rod, ball is housed on valve seat, this ball has a groove, and an end of valve rod is arranged in this groove, is provided with flange hole in valve body, seal ring is housed on valve rod, it is characterized in that: on valve rod, be provided with two seal rings at least, on handwheel, be provided with mobilizable handle, location piece is housed in valve body, valve rod is connected with location piece, on valve body, be provided with cover plate, on location piece, be provided with projection, on the cover board be provided with breach.
The utility model adopts double-sealing; solved the problem of easy leakage; handle is mobilizable the connection with handwheel, and regulating handle increases the arm of force as required, makes operation free and relaxed; this product has oil resistant, anti-corrosion, high-low temperature resistant (+260 degree are to-250 degree); long service life, easy to operate, it is quick to put oil into; helping advantages such as environmental protection, is desirable transformer fuel outlet valve substitute products.
