Abstract
The utility model discloses a butterfly valve opening and closing limiting device for a transformer, which comprises a limiting fixed plate and a valve rod protective handle; the limiting fixing plate is provided with a valve rod handle protecting hole, the lower surface of the limiting fixing plate is provided with a limiting groove, and the left side surface and the right side surface of the limiting groove are positioned at two sides of the valve rod handle protecting hole; a blind hole in the center of the valve rod guard handle is matched with the valve rod, a sealing ring groove is formed at the lower end of the blind hole, and a limit stop matched with the limit groove on the limit fixing plate is arranged on the outer edge of the lower end part of the blind hole; the distance between the fixing hole and the center of the valve rod handle protecting hole is unequal. The utility model discloses simple structure, reliability height, not fragile, longe-lived. The fixed mounting of the limiting fixing plate has good directivity and is not easy to be reversely mounted, the misoperation in the assembling and overhauling processes is eliminated, the production efficiency is improved, and the requirement on the skill of a user is reduced. Installation the utility model discloses an easy discernment of opening and the closed condition of butterfly valve is favorable to remote supervision and observes its state.
Description
One, affiliated technical field:
The utility model belongs to a kind of transformer and opens and closes stopping means with butterfly valve.
Two, background technology:
Existing transformer opens and closes stopping means with butterfly valve, protecting handle by fixed head and valve rod forms, valve rod protects the upper surface of handle and the upper surface of spacing fixed head is carved with the sign of butterfly valve opening and closing respectively, be fixed with spacing bumping post on the butterfly valve seat, the lower surface that valve rod protects handle has the loose slot of spacing bumping post.Because spacing bumping post is fixed on the butterfly valve seat, its connection reliability is poor, fragile, life-span weak point.And the fixed head both sides have, and to be installed in the distance that fixing hole on the valve seat and the valve rod on it protect the delthyrium center equidistant, like this, fixed head does not fixedly mount direction, when being installed on the valve seat easily about anti-dress, easily produce misoperation in the maintenance assembling process, reduced production efficiency, high to operator's technical ability requirement.
Three, summary of the invention:
The utility model solves the above-mentioned problems in the prior art exactly, and providing has the transformer of fixed installation direction to open and close stopping means with butterfly valve on a kind of reliability height, the fixed head.
For addressing the above problem, technical solution of the present utility model is: a kind of transformer opens and closes stopping means with butterfly valve, and it comprises that fixed head and valve rod protect handle; Fixed head is spacing fixed head, and valve rod protects the upper surface of handle and the upper surface of spacing fixed head is carved with the sign of butterfly valve opening and closing respectively; Have valve rod on the spacing fixed head and protect delthyrium, on its lower surface stopper slot is arranged, this stopper slot left and right sides face is positioned at the both sides that valve rod protects delthyrium; Valve rod protects the handle center and has the blind hole that is fixed together with valve rod, and blind hole and valve rod are complementary, and the blind hole lower end has seal groove, have on the outer rim of blind hole bottom with spacing fixed head on the positive stop that is complementary of stopper slot; Spacing fixed head has the fixing hole that is fixed together with butterfly valve seat on two side positions of stopper slot, the distance that fixing hole and valve rod protect the delthyrium center does not wait.
The upper end that above-mentioned described valve rod of the present utility model protects handle has one to protrude the indicator collet that valve rod protects the handle bar, and the sign that valve rod protects the upper surface of handle is engraved on the indicator collet.The indicator collet that protrudes makes human eye more easy to identify.
The utility model not only plays a protective role to the valve rod of butterfly valve, and lower end and valve rod that position limiting structure is positioned at spacing fixed head protect on the handle, it is simple in structure, reliability is high, not fragile, the life-span is long.It is not equidistant that fixing hole on the spacing fixed head and valve rod protect the delthyrium center, during installation, must install according to the position of fixing hole, can only a direction install, the fixed installation good directionality is difficult for anti-dress, eliminated the misoperation of assembling, maintenance process, improved production efficiency, reduced technical ability requirement the user.The opening and closing state that butterfly valve of the present utility model is installed is easy to identify, helps telemonitoring and its state of observation.
Four, description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is an installation diagram of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
