Abstract
The utility model discloses a double spring tube type sulphur hexafluoride controller which is a device used for controlling and measuring the density of sulphur hexafluoride. An indicating device and a control device are arranged in a casing. The position where a window is arranged at the back of the casing is provided with a back cover on which an O-shaped channel is arranged. An O-shaped o-ring seal is arranged in the O-shaped channel. A decorative cover fixedly connected with the casing is arranged outside the back cover. The utility model has the advantages that because the double spring tube type sulphur hexafluoride controller adopts the O-shaped o-ring seal, the sealing effect is good; the double spring tube type sulphur hexafluoride controller can be used as an oil charge type or a non-oil charge type and the dust and the oil can be better sealed; a circlip type decorative cover is pressed and the back cover is fixed; the appearance is beautiful and the volume is small; the height can be smaller than 83mm; the material is saved; the cost is decreased.
Description
Technical field
The utility model is the device that is used for sulfur hexafluoride density control and measures.
Background technology
Existing dual spring tubular type sulfur hexafluoride density controller is divided into oil-filled type and not oil-filled type, and oil-filled type adopts the mode of no bonnet, need not seal, but volume is big, highly reaches 94mm, takes material, and is not attractive in appearance; Not oil-filled type bonnet adopts the sealing of bayonet type nylon cushion, and sealing property is not good, can only seal dirt, can not oil sealing.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned not enough problem, and a kind of dual spring tubular type sulfur hexafluoride density controller is provided, good sealing effect, and can seal dirt again can oil sealing, and volume is small and exquisite and attractive in appearance.
The technical scheme that the utility model is adopted for achieving the above object is: dual spring tubular type sulfur hexafluoride density controller, indicating device and control device are housed in the housing, bonnet is equipped with in the position of windowing, housing rear portion, O type groove is arranged on the bonnet, O type O-ring seal is housed in the O type groove, and bonnet has trim to fixedly connected with housing outward.
Be equipped with open slot with the trim corresponding positions on the described housing, the circlip type trim sticks into the open slot internal fixation and connects.
The utility model has the advantages that: because adopt O type O-ring seal good sealing effect, can both well seal dirt, oil sealing, be pressed into the circlip type trim as filling type or filling type not, bonnet is fixed, and good looking appearance, volume is little, height can be saved material less than 83mm, reduces cost.
Description of drawings
Accompanying drawing is the utility model structural representation.
