Abstract

The utility model relates to a whole measuring range water gauge for the steam manifold of a boiler, comprising a water level gauge and the communicating pipe of steam and water. The whole measuring range water gauge for the steam manifold of a boiler is characterized in that the length of the measuring barrel of the water level gauge is equal to the diameter of a measured steam manifold or is lightly bigger than the diameter of the measured steam manifold; the communicating pipes of steam and water are respectively attached to the top part and the bottom of the steam manifold. Thus, the protection fixed value of a water level is enlarged, the damages of a boiler unit are avoided, and industrial loss is reduced. As water can be fed after the boiler is stopped, the lifetime of the steam manifold is extended. The structure of the utility model is simple; the whole measuring range water gauge for the steam manifold of a boiler can save a lot of losses for power boilers and industrial steam manifold boilers. Thus, the utility model is an ideal preparing product for the boiler.

Description

Whole measuring range water gauge for steam manifold of boiler

Boiler-steam dome gamut water level meter is a kind of device of measuring water level in power boiler and the Industrial Boiler.

Current, power boiler and Industrial Boiler, its steam water-level meter maximum range have only ± and 300 millimeters, can satisfy the demand at normal this water level meter in service.But raise because of operations staff's fault or unit exception generation water level sometimes or reduce, when water level surpasses ± 300 millimeters visible water levels, be called serious full water or serious water shortage, must handle by urgent left alone without help stove, otherwise bring certain loss to production.When drum dryouies pot, if the operations staff handles not according to urgent left alone without help stove, and blindly go up water, then may cause boiler badly damaged.

The purpose of this utility model is to provide a kind of drum gamut water level meter, this water level meter can clearly observe the height of water level in the whole boiler-steam dome, thereby remind the staff whether to need urgent left alone without help stove really, still lose no time to go up water, water or draining etc. on the stop that still loses no time.

The utility model is achieved in that it is by constituting water level meter and vapour, water communicating pipe, the measurement tube of water level meter equates with drum diameter total length, or be slightly larger than the diameter of drum, water level meter subscript is marked with three definite value numbers of corresponding boiler water protection: wetting system in the warning of I value, the automatic left alone without help stove of II value, III value (near the dryouting pot) locking, avoid device damage; To the heavy wall drum can be when the left alone without help stove waterborne to the drum top, so reduced stress, the prolongation drum life-span; Receiving vapour communicating pipe on drum top or steam guiding tube, extraction steam pipe, the manometer tube etc. of the water level meter of lengthening received on drum bottom or downcomer, recirculation pipe, the adjutage etc., thereby realized the gamut level measuring water communicating pipe.

The utility model is compared with prior art: amplified the water level protection definite value, avoided the boiler explosion, reduced a kind of loss for industry, prolonged the drum life-span.

Fig. 1: be prior art drum instrumentation plan.

Fig. 2: be the utility model drum instrumentation plan.

Lifting an example below in conjunction with accompanying drawing is elaborated:

If it is 1600 millimeters that its diameter of a drum is arranged; the water level range of existing technology (as Fig. 1) water level meter 3 has only ± and 300 millimeters; vapour communicating pipe 2 and water communicating pipe 4 all directly join with drum 1; the utility model (as Fig. 2); if the diameter of drum 1 is 1600 millimeters; the measurement tube of water level meter 6 also is 1600 millimeters or more bigger; connect vapour communicating pipe 5 and water communicating pipe 7 the top steam guiding tube 8 of drum and the downcomer 9 of bottom respectively, water level meter 6 subscripts are marked with water level protection three definite values 10: wetting system in the warning of I value, the automatic left alone without help stove of II value, the locking of III value.

The utility model can be at the direct perforate connecting leg in drum top and bottom to the coming of new boiler, and to the boiler that has put into operation, vapour, water communicating pipe receive on steam steam guiding tube and the downcomer, avoid the drum perforate.

Claims

1, boiler-steam dome gamut water level meter by constituting water level meter (6) and vapour communicating pipe (5), water communicating pipe (7), is characterized in that: the equal diameters of the measurement tube length degree of water level meter 6 and tested drum (1) or than drum slightly larger in diameter a bit.

2, water level meter according to claim 1, it is characterized in that receiving vapour communicating pipe (5) on drum top (8) or steam guiding tube or extraction steam pipe or the Pressure gauge, receive water communicating pipe (7) on drum bottom (9) or downcomer, recirculation pipe, the adjutage.

3, water level meter according to claim 1 and 2 is characterized in that water level meter (a 6) measurement tube subscript is marked with and corresponding water conservation three definite values of boiler (10): wetting system in the warning of I value, the automatic left alone without help stove of II value, the locking of III value.
