Abstract
The utility model relates to a kind of boiler drum water replanishing devices.Boiler drum water replanishing device includes drum and the water-supply valve and drain valve that are connected with drum, water-supply valve is connected with feed pump, drum is equipped with the chain automatic water replenishing system with water-supply valve chain control feed pump, chain automatic water replenishing system includes the double-chamber balancing vessel and differential pressure transmitter being connected with drum, double-chamber balancing vessel is just, negative pressure chamber respectively with the height of differential pressure transmitter, low-pressure end is connected, when liquid level of steam drum is low and water-supply valve or drain valve failure, feed pump is automatically replenished according to the signal of chain automatic water replenishing system, liquid level in place when, feed pump stops moisturizing according to signal.Liquid level can be remained constant by manually controlling the switch of water-supply valve, drain valve.It in the case where drum stop valve failure, with chain control and is automatically replenished and realizes the stabilization of liquid level, it is dual chain to realize drum moisturizing, reduces employee's upper water labor intensity manually, improves the safety of drum moisturizing.
Description
Technical field
The utility model relates to a kind of boiler drum water replanishing devices.
Background technique
Drum stop valve do not open or close frequent occurrence incessantly etc. failures, need operative employee to manually boot on feed pump in this way
Water, the water on a manual furnace one in the case where personnel shortage, it is also necessary to drum platform manual switch by-passing valve is arrived upstairs, if any not
It is careful to will cause drum water shortage, equipment safety accident is caused, causing stokehold pressure to mention rifle cannot normally produce, or even drum occurs
It explodes pernicious safety accident, influences the personal safety of factory department's normal production order and on-site personnel.
Summary of the invention
In order to overcome the drawbacks of the prior art, the purpose of the utility model is to provide one kind can be improved drum moisturizing safety
The chain water replanishing device of drum of property.
In order to achieve the goal above, the technical solution of the utility model boiler drum water replanishing device is:
Boiler drum water replanishing device includes drum and the water-supply valve and drain valve that are connected with drum, water-supply valve and feed pump phase
Even, drum is equipped with chain automatic water replenishing system with water-supply valve chain control feed pump, chain automatic water replenishing system include with
Drum connected double-chamber balancing vessel and differential pressure transmitter, the positive and negative pressure chamber of double-chamber balancing vessel respectively with differential pressure transmitter
High and low pressure side is connected, and when liquid level of steam drum is low and water-supply valve or drain valve failure, feed pump is according to chain automatic water replenishing system
Signal automatic water supplement, liquid level in place when, feed pump according to signal stop moisturizing.
Further, it is connected with jet chimney at the top of drum, diffusion valve is installed on jet chimney.
Due to the implementation of above technical scheme, the utility model has the following technical effect that this reality compared with prior art
In novel, liquid level can be remained constant by manually controlling the switch of water-supply valve, drain valve.In drum stop valve failure
In the case of, it with chain control and is automatically replenished and realizes the stabilization of liquid level, it is dual chain to realize drum moisturizing, reduces employee's hand
Dynamic upper water labor intensity, improves the safety of drum moisturizing.
Detailed description of the invention
Fig. 1 is the schematic diagram of the boiler drum water replanishing device of the utility model.
Specific embodiment
The technical solution of the utility model is described in detail below by specific embodiment.
As shown in Figure 1, boiler drum water replanishing device includes drum 1, water-supply valve 3, drain valve 4, release are connected on drum 1
Valve 7 and chain automatic water replenishing system 6, water-supply valve 3 are connected with feed pump 5, and diffusion valve 7 is located on the jet chimney at the top of drum,
Item 2 indicates drum fluid columns.Chain automatic water replenishing system 6 is additionally provided on drum 1, chain automatic water replenishing system 6 and water-supply valve 3 are chain
Feed pump 5 is controlled, including the double-chamber balancing vessel and differential pressure transmitter being connected with drum, the positive and negative pressure chamber of double-chamber balancing vessel
It is connected respectively with the high and low pressure side of differential pressure transmitter, the current signal of transmitter output is sent to analog module, carries out liquid automatically
Moisturizing, the draining of position, principle are the prior art.
When liquid level of steam drum is low and water-supply valve or drain valve failure, feed pump according to the signal of chain automatic water replenishing system from
Dynamic moisturizing, liquid level in place when, feed pump stops moisturizing according to signal.
When not having to automatic, by manually controlling the switch of water-supply valve, drain valve, liquid level is remained constant.It is cut in drum
In the case where disconnected valve failure, the stabilization of liquid level is realized with chain control, the stabilization of liquid level of steam drum is realized in dual moisturizing.It realizes
Drum moisturizing is dual chain, reduces employee's upper water labor intensity manually, improves the safety of drum moisturizing.
Finally, it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations；
Although the utility model is described in detail with reference to the foregoing embodiments, those skilled in the art should understand that:
It is still possible to modify the technical solutions described in the foregoing embodiments, or part of technical characteristic is carried out etc.
With replacement；And these are modified or replaceed, various embodiments of the utility model technology that it does not separate the essence of the corresponding technical solution
The spirit and scope of scheme.
