Abstract
The utility model relates to an external automatic water feeding device for a boiler, which comprises a float box and a floating ball valve with a small hole, wherein a steam communicating pipe and a water communicating pipe which are arranged on the float box are respectively connected with a steam space and a water storage space of a boiler body. A float and a float rod are fixed to an action lever of the floating ball valve with a small hole, the external form of a valve cap of the floating ball valve with a small hole is a flange disk which is fixed to a flange seat of the float box by a screw, a water inlet of the floating ball valve with a small hole is connected with a tap water pipe and a water outlet is connected with the bottom of the boiler body through a water supply pipe. The utility model has the characteristics of rapid and timely water feeding, synchronous increase of the water level of the boiler body and the water level of the float box, easy fabrication, low cost, little possibility of ageing for rubber sealing elements and long service life.
Description
The auxilliary moving automaton of using on a kind of steam boiler.
" the steam boiler " that No. 96206970 patents propose with external automatic watering apparatus, though that its automatic watering apparatus is positioned at pot is external, processing, installation, maintenance ratio are easier to, and have following weak point:
1. when water level descends in the pot body, running water at first enters in the float tank by the aperture ball-cock assembly, the float tank water level is raise, rely on small water-head pressure between float tank and the pot body then, flow to lentamente in pot body, cause a pot body water level to lag behind float tank, can not obtain make-up water in time.
2. in order to accelerate the speed that water enters pot body from float tank, must do the communicating pipe between them very thick, therefore improve cost of manufacture.
3. will make facilities such as special-purpose valve box, valve bonnet, cost of manufacture is higher.
4. have only one deck rubber removable cover to be separated by between float tank and the valve bonnet, cause the aperture ball-cock assembly in the valve bonnet still to be in than in the higher temperature environment, the rubber element that seals in the valve is easily aging, needs often to change, and service life is short.
The purpose of this utility model provides the external automatic watering apparatus of a kind of improved boiler, accomplishes to give pot body make-up water, low cost of manufacture, long service life in time.
The purpose of this utility model is achieved in that to be improved No. 96206970 patents, the valve gap profile of aperture ball-cock assembly is changed system into ring flange, directly be installed on the flange seat of float tank with screw, the water inlet of aperture ball-cock assembly connects running water pipe, and delivery port connects bottom of pot body by feed pipe.
Fig. 1 is the external automatic watering apparatus structural representation of boiler.
Fig. 2 is float tank and aperture ball-cock assembly parts master cutaway view.
Describe concrete structure of the present utility model and operation principle in detail below in conjunction with Fig. 1, Fig. 2 and embodiment.
As shown in the figure, the utility model includes float tank 2 and aperture ball-cock assembly 7, there are vapor communication pipe 3, water communicating pipe 4 to link to each other with water storage space with the vapor space of pot body 1 respectively on the float tank 2, float and float lever 6 are fixed on the action lever 71 of aperture ball-cock assembly 7, difference is that valve gap 72 profiles of aperture ball-cock assembly 7 are ring flange, be fixed on screw on the flange seat 21 of float tank 2, the water inlet 73 of aperture ball-cock assembly 7 connects running water pipe, and delivery port 74 is pressed pot body 1 bottom by feed pipe 8.
Intake antrum 75, pressure chamber 76 are arranged in the valve body of aperture ball-cock assembly 7.Movable spool 9 is formed by interior cover 91, overcoat 92 and tripod fairlead 93 mutual rotation sets.Be set with a bowl type rubber seal 94 between interior cover 91 and the overcoat 92, be with ring-like rubber seal 95 between overcoat 92 and the tripod fairlead 93.Head portion include valve pocket lid 77, stem head 78, valve head cover 79 and on action lever 71, little delivery port 70.Valve rod 96 passes the central small hole of movable spool 9 and valve pocket lid 77, and right-hand member is fastened on the stem head 78, and spring 97 is between movable spool 9 and valve pocket lid 77, and rubber gasket 98 is enclosed within on the valve rod 96, between valve pocket lid 77 and stem head 78.
Operation principle of the present utility model is as follows:
When pot body 1 water level raise, float tank 2 water levels rose thereupon, and the buoyancy of float 5 drives action lever 71, and stem head 78 is moved to left, and pushes down rubber gasket 98, closed valve pocket lid 77.At this moment, the water that enters in the pressure chamber 76 along central small hole begins to increase pressure, and under the cooperation of spring 97, promotion activity spool 9 moves to left, and makes ring-like rubber gasket 95 close water inlet 73, and running water stops to enter pot body 1.Because pressure chamber 76 sectional areas are that the water inlet sectional area is more than 2 times, under the situation that hydraulic pressure equates by force, water is water inlet 73 place's water more than 2 times of propulsive thrust to movable spool 9 to the pushing force of movable spool 9 in the pressure chamber 76, thereby makes water inlet 73 places tight-closed reliable.
When pot body 1 water level descended, float tank 2 water levels descended, and the gravity of float 5 drives action lever 71, and stem head 78 is moved to right, and rubber gasket 98 is thrown off valve pocket lid 77.At this moment, the water in the pressure chamber 76 enters float tank 2 by little delivery port 70, and the pressure of water reduces in the pressure chamber 76, and running water promotion activity spool 9 moves to right, and water inlet 73 places are opened, and a large amount of water directly enters in pot body 1 through delivery port 74, feed pipe 8.
In the present embodiment, delivery port 74 is directed upwardly, and the feed pipe 8 on it is an inverted U.Purpose is when stopping into water, and remaining the valve body upper end has one section cold water, to weaken the influence of heat conduction to valve body, whole valve is operated in the lower temperature environment, thus the ageing process that prolongs rubber sealing element more.
Compared with the prior art, the utility model has following characteristics:
1. water inlet is in time quick, and a small amount of water enters float tank, and big water gaging directly enters a pot body through feed pipe, Guarantee the simultaneous growth of pot body water level and float tank water level.
2. the aperture ball-cock assembly, is therefore made easily as long as parts such as valve gap are just transformed a little and can be used on sale on the market.
3. saving raw material, cost of manufacture is low.
4. rubber sealing element only contacts with cold water basically, therefore is difficult for wearing out long service life.
