Abstract
The utility model provides a multifunctional tube oil level displaying device, belonging to a component of the transformer and essentially applicable to the fully-enclosed oil filling power distribution transformer, which comprises a tube with an observing window, a glass tube, a float and a blind flange or a pressure release valve and so on; the structure is characterized in that the tube end is provided with a top installation base or a bottom installation base as the tube accessory, and the glass tube is able to be provided with the tube or the inner wall of the bottom installation base or the top installation base as the tube accessory in a seal mode; the bottom of the tube or the tube accessory is provided with a bolt or a pin or a post through and fixed on the tube or the tube accessory wall, being taken as a float orientation limit component, and moreover, the float or the float synchronous component is provided with a notch or a slot cooperating with the float orientation limit component; besides, a flange sleeve is positioned on the tube or the outer wall of the bottom installation base bottom, which is able to sleeve the float orientation limit component. Except for solving the problems of a comparatively complex structure and an inconvenient installation, the utility model further settles the issues that the prior art provides an inflexible assembling and the float limit is not able to limit the rotation and so on.
Description
Technical field
The utility model belongs to a kind of parts of transformer, be mounted on the transformer case in order to show the device of the gas that fuel tank internal oil level or storage fuel tank internal produce, and venting, minimum oil level or functions such as excess air monitoring, pressure release are arranged, mainly be applicable to hermetically sealed oil-filled substation transformer.
Background technology
At present, the used multi-functional preferably tubular type oil level display device of hermetically sealed oil-filled substation transformer is that the patent No. is ZL 01241627.4, and name is called a kind of multi-functional tubular type oil level indicator.Its objective is the minimum oil level that shows the fuel tank internal upper part, prevent solar radiation oil, can in time monitor minimum oil level or excess air, can gather gas or pressure release etc.Its primary structure is: have one or several inspection hole on body top, be equipped with and inboard wall of tube body sealed glass pipe at the inspection hole place, bottom in body is equipped with float, on float, be equipped with the mark spare that shows the oil level mark, be equipped with flange or the pressure relief valve of being with air relief cock or getting gas sample valve in the sealing of body upper end; On the lower inner wall of body, be provided with the locating part of float domain of walker, the technical matters of its existence is: 1, because the locating part of the float domain of walker of this structure needs two up and down, and the locating part of lower end need be installed in that body extends to fuel tank internal part or the position-limited rack established in addition on, and can only limit float domain of walker up and down, and can not limit the rotation of float, therefore structure is complicated, and the spacing circumferencial direction that can not limit of float rotates; 2, because its lower end and the installation of transformer case lid are to be fixed on the flange seat that is welded with on the case lid with the flange of bolt with its lower end, so structure is complicated, and inconvenience is installed; 3, because glass tube only seals with inboard wall of tube body, therefore assemble dumb sometimes.
Summary of the invention
Be to solve the technical matters that exists in the prior art, the utility model will provide assembling flexibly, can limit float rotate, simple in structure, more convenient multi-functional tubular type oil level display device is installed.
The technical solution adopted in the utility model is: it comprises body, glass tube, float, blind flange or the pressure relief valve etc. that have inspection hole, its architectural feature is: mount pad or following mount pad on can being equipped with as the body annex in the end of body, and glass tube can or be gone up mount pad or the inner wall sealing installation of mount pad down with body; Be equipped with the screw that passes and be fixed on body or the body annex wall or pin or post in the bottom of body or body annex as the directed locating part of float, and on the synchronous piece of float or float, be provided with the directed locating part of float and stretch into notch or the groove that body or body annex inner wall section match; Thread connection has the mounting flange cover on the lower end outer wall of body or following mount pad, and the directed locating part of float can be entangled at body or following mount pad outer wall section in the internal diameter top of mounting flange cover.
The utility model beneficial effect compared with prior art is:
1, because mount pad or following mount pad on can being equipped with as the body annex in the end of body, and glass tube can with body go up mount pad or down the inner wall sealing of mount pad install, therefore assembling flexibly, reliable;
2, because the utility model adopts screw or pin or post as the directed locating part of float, and it matches with notch or groove that the synchronous piece of float or float is provided with, therefore not only can carry out spacing up and down to float, but also can limit the rotation of float, simultaneously do not need the extension of body lower end or establish position-limited rack in addition, simple in structure;
3,, therefore easy for installation, simple owing to be connected with the mounting flange cover at body or as the lower end screw thread of the following mount pad of body annex; Again because the mounting flange cover can entangle the directed locating part of float part at body or as the following mount pad wall of body annex outside, can prevent the loosening of the directed locating part of float or come off, so further improve reliability.
Description of drawings
Accompanying drawing is the utility model example structure synoptic diagram.
Among the figure: 1, body, 1a, inspection hole, 2, float, 2a, notch or groove, 3, oil level mark spare, 4, glass tube, 5, pressure relief valve, 6, mount pad down, 7, the directed locating part of float, 8, the mounting flange cover, 9, go up mount pad.
Embodiment
With reference to accompanying drawing.The embodiment of the utility model embodiment comprises: have body 1, glass tube 4, pressure relief valve 5 or blind flange, the float 2 of inspection hole 1a and the oil level mark spare 3 that is equipped with above thereof etc., its architectural feature is: mount pad 9 or following mount pad 6 on can being equipped with as the body annex in the end of body 1, and glass tube 4 can or be gone up mount pad 9 or the inner wall sealing installation of mount pad 6 down with body 1; Be equipped with at body 1 or as the bottom of the following mount pad 6 of body annex and pass and to be fixed on body 1 or the screw on mount pad 6 walls or pin or post and are provided with notch or the groove 2a that stretches into body 1 or match as following mount pad 6 inner wall section of body annex with the directed locating part 7 of float as the directed locating part 7 of float on the synchronous piece of float 2 or float 2 down; Thread connection has mounting flange cover 8 on the lower end outer wall of body 1 or following mount pad 6, and the directed locating part 7 of float can be entangled at body 1 or following mount pad 6 outer wall sections in the internal diameter top of mounting flange cover 8.
During use, mounting flange is overlapped 8 sealing and fixing on the fuel tank cap of transformer, with body 1 or down the threaded portion of mount pad 6 bottoms screw in mounting flange cover 8 and sealing and fixing gets final product.When the oil level in the oil tank of transformer when the scope of regulation rises or descends, can see that oil level mark spare has demonstrated oil or do not had oil by inspection hole 1a.Simultaneously, define on the float by the directed locating part 7 of float with notch or groove 2a or domain of walker down and control float 2 and do not rotate.
