Abstract
The utility model relates to a kind of steam generator relief valve mechanism.This mechanism comprises water pump and steam generator, is connected between water pump with steam generator by tube connector, and described water pump and the junction of tube connector or tube connector stage casing are provided with a relief valve.Relief valve is arranged on the connecting line of water pump and steam generator by steam generator relief valve mechanism of the present utility model, assemble when producing in steam generator, when air pressure raises, pressure in tube connector increases, when pressure reaches the operating pressure of relief valve, relief valve and beginning pressure release, pressure now in steam generator decreases, play the pressure release effect simultaneously to pipeline and steam generator, avoid the problem can not taking into account tube connector when only the pressure of steam generator being controlled, further increase the security of use.
Description
Technical field
The utility model relates to a kind of steam pipework mounted valve, especially a kind of steam generator relief valve mechanism.
Background technology
The blower fan of smoke exhaust ventilator is stained with a large amount of oil stain, and the general high-temperature steam that adopts heats oil stain, makes its deliquescing, expands, comes off, and realizes clean.Steam raising plant is sent to steam generator by water plug water source and is heated and sprayed by nozzle, realizes HIGH TEMPERATURE PURGE.Generally water pump is connected with steam generator by pipeline in existing steam generator, when steam generator works, inner pressure is larger, when running into internal duct blocking or give vent to anger not smooth, pressure inside steam generator can increase, easy generation is sharply expanded and produces explosion, so some products are arranged on steam generator pressure relief mechanism to carry out pressure release, but because steam generator is directly connected with pipeline, steam generator generally adopts to be had the certain thickness housing of some strength and makes, its pressure that can bear often is greater than the pressure that pipeline can bear, and tube connector generally adopts silicone tube or other soft pipelines to make, in steam generator during pressure increase, and when not reaching the operating pressure of pressure relief mechanism, the pressure at tube connector place often exceeds tolerance range, so still there is explosion danger in tube connector place.
Utility model content
The utility model proposes a kind of steam generator relief valve mechanism, solve the easy pressure increase in tube connector place in prior art and produce the problem of explosion.
The technical solution of the utility model is achieved in that
This mechanism comprises water pump and steam generator, is connected between water pump with steam generator by tube connector, and its improvement is: described water pump and the junction of tube connector or tube connector stage casing are provided with a relief valve.
Preferably, described relief valve comprises a valve casing, and described valve casing is provided with feed tube, drain pipe and relief tube, is provided with spool in valve casing.
Preferably, described feed tube is communicated with setting with drain pipe level, and described relief tube upwards extends perpendicular to feed tube and drain pipe.
Owing to have employed such scheme, relief valve is arranged on the connecting line of water pump and steam generator by steam generator relief valve mechanism of the present utility model, assemble when producing in steam generator, when air pressure raises, pressure in tube connector increases, when pressure reaches the operating pressure of relief valve, relief valve and beginning pressure release, pressure now in steam generator decreases, play the pressure release effect simultaneously to pipeline and steam generator, avoid the problem can not taking into account tube connector when only the pressure of steam generator being controlled, further increase the security of use.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the cross section structure schematic diagram of the utility model first embodiment;
Fig. 2 is the cross section structure schematic diagram of the utility model second embodiment.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the steam generator relief valve mechanism of the first embodiment of the present utility model comprises water pump 1 and steam generator 2, be connected by tube connector between water pump 1 with steam generator 2, described tube connector comprise the water pump efferent duct 3 that is connected with water pump 1 and be connected with steam generator 2 steam generator input pipe 4, be provided with a relief valve 5 between described water pump efferent duct 3 and steam generator input pipe 4.
During work, water pump 1 injects the water of band evaporation by tube connector in steam generator 2, and water is carried out high-temperature evaporation in order to using by steam generator 2, and now relief valve 5 is in breakthrough status, and current are pressed normal work path and run; When steam generator 2 operation irregularity, internal pressure increases, cause the also corresponding increase of the pressure in pipeline, when reaching the operating pressure of relief valve 5, relief valve 5 is got involved work and is carried out pressure release, to ensure that pipeline does not produce explosion because of excessive pressure, also ensure that the job security of steam generator 2 simultaneously.
Concrete, in the present embodiment, described relief valve 5 comprises a valve casing 51, and described valve casing 51 is provided with feed tube 52, drain pipe 53 and relief tube 54, is provided with spool 55 in valve casing 51.
Specifically arranging at pipeline, in the present embodiment, described feed tube 52 is communicated with setting with drain pipe 53 level, and described relief tube 54 upwards extends perpendicular to feed tube 52 and drain pipe 53.
Above-mentioned first embodiment illustrate be tube connector relief valve being installed on water pump and steam generator stage casing on structure, in second embodiment of the present utility model, as shown in Figure 2, water pump 1 and steam generator 2 adopt the tube connector 6 of whole section to be connected, then relief valve 5 is installed on the junction of water pump 1 and tube connector 6, the feed tube of relief valve 5 is connected to the exit of water pump 1, and the drain pipe of relief valve 5 is connected to the porch of tube connector 6.During work, when steam generator 2 operation irregularity, internal pressure increases, cause the also corresponding increase of the pressure in pipeline, when reaching the operating pressure of relief valve 5, relief valve 5 is got involved work and is carried out pressure release, to ensure that pipeline does not produce explosion because of excessive pressure, also ensure that the job security of steam generator 2 simultaneously.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
