Abstract
The utility model relates to a liquid level sensor used in equipment with strict requirements for sealing property and the liquid level of equipment needs controlling, such as a vacuum boiler and an oil field vacuum heating furnace. The adjustable dual sealed liquid level sensor comprises an electrode with one end inserting into the boiler and a binding post seat which is fixed at the top or side of the boiler through a flange. Holes for electrode inserting through are arranged inside the binding post seat. The electrode is fastened at inner side of a binding post, close to the boiler through an inside nut. The electrode is fastened at outer side which is opposite to the inner side of the binding post through an outside nut. A sealing gasket is arranged at a contact place between the electrode and the inner side of the binding post, and a sealing gasket is arranged at a contact places between the electrode and the outer side of the binding post. The installation site of the adjustable dual sealed liquid level sensor is not limited. The adjustable dual sealed liquid level sensor is characterized by being strong in adaptability, good in sealing property, low in cost, simple in structure and reliable in performance, and the liquid level can be adjusted.
Description
Technical field
The utility model relates to a kind of liquid level sensor of and device that liquid level need control strict for seal requests such as vacuum boiler or oil field vacuum furnaces.
Background technology
At present, vacuum boiler or oil field vacuum furnace are owing to the advantages such as safe and reliable, energy-efficient, strong adaptability and life-span be long are found broad application.Yet if cause vacuum tightness to descend owing to vacuum drying oven is poorly sealed, the vacuum drying oven performance will be greatly affected.Simultaneously, matchmaker's water water level of vacuum drying oven also directly injures the safety of vacuum drying oven as can not get reliable control.The fluid level controller of classic method not only cost is high and do not possess adjustability, and often the installation of fluid level controller only is confined to the side of vacuum boiler and the structural arrangement of vacuum boiler is affected.
Summary of the invention
The purpose of this utility model is, for the deficiencies in the prior art, provides a kind of adjustable dual seal liquid level sensor, and the installation site of sensor is unrestricted, and electrode to go deep into liquid level adjustable, good seal performance.
The technical solution of the utility model is, a kind of adjustable dual seal liquid level sensor, comprise that an end inserts the electrode in the boiler, also comprise the wiring column base that is fixed to boiler end face or side by flange, and be provided with the hole that power pole is passed in the wiring column base, and electrode is fastening by inner screw nut and outboard nut respectively near the medial surface of boiler and the lateral surface relative with medial surface at the wiring column base; Gasket seal is installed respectively in the medial surface of electrode and wiring column base and the contact position of lateral surface.
Sensor described in the utility model can be fixed to boiler end face or side, is not subjected to the restriction of installation site; Unscrew inner screw nut and outboard nut, the length of electrode in the boiler is goed deep in decision according to the vacuum drying oven liquid level, again with nut screwing clamping; Gasket seal is installed respectively in the medial surface of electrode and wiring column base and the contact position of lateral surface, reaches the effect of double seal, and finally the binding post by electrode tip passes to control system with signal, to reach the purpose of liquid level control.
Wiring column base lateral surface is provided with the gland bonnet that covers on the electrode, and electrode is protected and sealed.
As known from the above, adjustable dual seal liquid level sensor described in the utility model, the installation site is unrestricted, has strong adaptability, good seal performance, the characteristics that liquid level control is adjustable, and cost is low, and simple in structure, dependable performance.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
