Abstract
A steam boiler comprises a boiler body, a water supply system, a water level gauge, a steam outlet valve and a pressure gauge are connected on the boiler body; the steam boiler is characterized by further comprising a vacuum breaking valve which is communicated with the steam space of the boiler body. In use, the steam boiler can solve the problems that in the prior art, after the steam boiler and the corresponding pipeline system stop running, the internal space generates higher vacuum due to cooling of the boiler, and the supply water in the water supply system is sucked into the vacuum to form a full condition, or pipe fittings and equipment connected with the pipeline are difficult to be switched on and off, even existing potential safety hazards or safety accidents. The steam boiler is safe and convenient to use and strong in practicability.
Description
Technical field
The utility model relates to a kind of steam boiler, the particularly a kind of steam boiler that can eliminate the boiler vacuum state.
Background technology
Boiler is heat energy or other energy that utilizes fuel combustion to discharge, and working medium is heated to the equipment of certain parameter.Be applied to add the boiler that hot water makes it to change into steam and be called steam boiler.It is very extensive in sector applications such as clothes, chemical industry, medicine, weaving, papermaking, and sphere of lifes such as civil heating also need boiler to supply with a large amount of heat energy.In light industry, apparel industry, widely applying operating pressure to be less than or equal to 0.7MPa, saturated-steam temperature is less than or equal to 170 ℃ small steam boiler.On the method for operation, then need often (every day even shorter) blowing out continually, particularly at night.After the blowing out, cooling along with the body of heater of boiler, the steam of boiler internal is because of after cooling condenses into water, volume dwindles extremely significantly and makes boiler internal produce higher vacuum, at this moment, if the valve of pipe-line system still is under the running status during unmanned, will suck the feedwater in the water supply system and form full water state, perhaps because the vacuum state in boiler and the pipeline thereof, make pipe fitting or the equipment that is connected is difficult to open and close operation, it is to having potential safety hazard or security incident taking place.
Summary of the invention
At above shortcomings in the prior art, the present invention aims to provide a kind of vacuum state of eliminating, and has safe in utilization, steam boiler easily.
Described steam boiler comprises body of heater, is connected with water supply system, water level meter, gas outlet valve, safety valve and Pressure gauge on the body of heater, it is characterized in that this steam boiler also comprises the air admission valve that is connected with the vapor space of body of heater.
Described steam boiler, it is characterized in that described air admission valve is made up of valve rod, valve seat, O-ring seals, valve gap and valve body, valve rod is between valve body, valve gap and valve seat, it can move by free lifting in valve body, the valve rod top is set with the O-ring seals mobile along with valve rod, valve body is threaded with valve gap, and valve seat is between valve body and valve gap.
Described steam boiler is characterized in that described water supply system mainly is formed by connecting by pipeline by feed-tank, feed pump, feedwater/check-valves.
Described steam boiler is characterized in that described bottom of furnace body is equipped with blowoff valve.
Described steam boiler is characterized in that described air admission valve is arranged on water level meter upper end.
Described steam boiler is characterized in that described water level meter lower end is provided with water level meter flushing/blowoff valve.
Compared with prior art, the utility model has installed an air admission valve additional on steam boiler and node that the vapor space is connected after, when this boiler stops/finishing operation, after the boiler cooling, working medium in the boiler will reduce temperature and pressure because of cooling, until condensing into water, form vacuum state.Air admission valve will be opened automatically, and boiler internal is connected with atmosphere, no longer produce vacuum state.Need not manually-operated and on duty, also can not produce because of the formed potential safety hazard of vacuum, operating difficulties or the full water state that forms naturally.In addition, bottom of furnace body of the present utility model is provided with blowoff valve, in time clears up the booty of body of heater inside, to guarantee water quality; The water level meter that is provided with is convenient to observe intuitively water level; Above-mentioned steam boiler has safety, convenient, cheap, uses advantages such as reliable.

Among the figure: the 1-gas outlet valve; The 2-safety valve; The 3-body of heater; The 4-feed-tank; The 5-feed pump; 6-feedwater/check-valves; The 7-blowoff valve; The 8-Pressure gauge; The 9-air admission valve; 10-water level meter; 11-water level meter flushing/blowoff valve; The 12-valve rod; The 13-valve seat; 14-O shape sealing ring; The 15-valve gap; The 16-valve body.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
The utility model comprises body of heater 3, is connected with water supply system, gas outlet valve 1, safety valve 2 and Pressure gauge 8 etc. on the body of heater 3, and wherein, water supply system mainly is formed by connecting by pipeline by feed-tank 4, feed pump 5, feedwater/check-valves 6; In order to make the boiler plant trouble free service, an air admission valve 9 can be acquired, on the cylindrical shell that is directly installed on body of heater 3 at boiler plant or in its pipe-line system.This air admission valve 9 is made up of valve rod 12, valve seat 13, O-ring seals 14, valve gap 15 and valve body 16, valve body 16 belows are connected with the base of gas thread with the vapor space of steam boiler, valve gap 15 also is connected with screw thread with valve body 16, should tighten during use.Valve seat 13 is arranged between the two, and the faying face after tightening between them can not leak; Valve rod 12 is between valve body 16, valve gap 15 and the valve seat 13, and it can move by free lifting in valve body 16; Valve rod 12 tops are set with O-ring seals 14, move along with valve rod 12.When valve body and below have pressure, steam will promote valve rod 12 and O-ring seals 14 moves up and with valve seat 13 auto-closings, can not leak vapour; And when valve body and below do not have pressure or be in vacuum state, valve rod 12 and O-ring seals 14 will fall, and be in automatic opening, make it to communicate with outside atmosphere, destroy the vacuum state of inner chamber.In order to guarantee the cleaning of water in the body of heater 3, body of heater 3 bottoms are equipped with blowoff valve 7, are convenient in time clear up stolen goods water and foreign material etc.Be equipped with water level meter 10 on the body of heater 3 and be used for monitoring intuitively the water level of body of heater 3, water level meter 10 lower ends can be provided with water level meter flushing/blowoff valve 11, can in time clean when in water level meter 10 tube chambers dirt being arranged, and it is more clear to make the observation of water level; Air admission valve 9 also can be arranged on the top of water level meter 10, is connected with the vapour communicating valve of water level meter, perhaps is installed in other positions that are connected with the vapor space of boiler.
The utility model only needs to acquire an air admission valve at boiler plant or in its pipe-line system, can reach the purpose of this boiler plant trouble free service.When it normally moves at boiler, promote the valve rod of air admission valve and, can provide steam supply qualified, safety this valve closure by the steam pressure in the boiler; When boiler was in the blowing out state, it can be opened automatically, and boiler is connected with atmosphere, can not produce vacuum state, guaranteed boiler plant and was attached thereto the safety of the system that connects, and used very convenient.And because structure is very simple, with low cost, very easy to utilize, this air admission valve not only can be applied in garment production, the service industry, at sphere of lifes such as industries such as chemical industry, medicine, weaving, papermaking, food and civil heatings, all has the prospect of applying.The utlity model has advantages such as safe, convenient, cheap, practical.
