Abstract
A method for automatically feeding a closed liquid system from a liquid source according to need by creating between the liquid source and the closed liquid system a load buffer formed from liquid, in which between the liquid source and the feed buffer only liquid flow in the direction of the feel buffers is allowed and from the feed buffer to the closed liquid system only drorpwise liquid transport is admitted. The feed buffer can be realized with a cylindrical drip feeder with inlet, outlet and freely movable plunger, which can close the outlet in an abutting position while leaving clear a minuscule leakage channel and is provided with a passage with a non-return valve in the direction of the inlet. Such a drip feeder can, with or without insertion of a storage container for liquid, be connected with, for instance, a liquid system, such as a central heating system with pipe system, boiler and expansion tank.
Description
The present invention relates to a kind of being used for as required from fluid supply is the method for closed liquid system (for example central-heating system or be designed to the another kind of heat exchange or the treatment system in sealing liquid loop) self-feeding, wherein in this system, the feeding buffer that generation is formed by liquid, and between fluid supply and feeding buffer, only allow liquid to flow along feeding buffer direction.The invention still further relates to a kind of the dripping of this method of can being used for realizing, and wherein adopted described method and described heating system to conveyer to conveyer.
From WO-A-00/19149, can understand aforesaid method.Preserve the liquid material stock in the deaerating chamber therein, it passes through to float control valve from fluid supply as required, more particularly comes supply from public water supply system.In this method, no matter when during feeding, must guarantee, for example because under the situation of the increase of the pressure in liquid system or decline of the pressure in fluid supply or pressure fault, any fluid of closed liquid system all cannot enter in the source of carrying out feeding.Also must guarantee when disaster occurring and for example in liquid system, pipeline break occurs, can on sizable degree, cut off supply at least, thereby can not aggravate this disaster from fluid supply.
To with reference to central heating apparatus these problems be illustrated in greater detail in the mode of embodiment below.This sealing liquid closed circuit with variable temperature and pressure often adopts a kind of expansion tank, thereby when variations in temperature, can adapt to the increase and the minimizing of sealing liquid volume, does not increase and excessive pressure can not occur.In addition, in fact in this sealing liquid closed circuit, especially when relating to central heating apparatus, be difficult to get rid of the fluid loss that has from loop.So many liquid can be missed from this closed system, becomes apparent and will compensate thereby leak.When this amount hour, be difficult to detect the position of leakage, perhaps detect and will have great difficulty.In addition, to such an extent as to the hydraulic slip amount can very little this liquid almost just all evaporations at once, when oozing out leakage loss, though be not do not have mark at all can be target-seeking, also be difficult to pursue trace.When measuring for a long time in the heating equipment at 40kW, find that it approximately is 0.8cc/24 hour that these no marks can target-seekingly ooze out leakage loss, this season will be equivalent to about 300cc a heating.
Have or do not have the leakage water of caution to be collected into specific degrees by expansion tank, this expansion tank can be considered as a supply source, but can only be as a restrictive or limited supply source.If this supply source is depleted, continue so again to leak, the pressure in this sealing liquid closed circuit will descend rapidly, is dropping under the specified pressure, for example when the pressure in the heating equipment drops to atmospheric pressure, can cause the automatic cut-out of equipment operation.For central heating apparatus, this can cause catastrophic consequence, for example at frosty night.Can prevent everything generation by the replenishing method as shown in WO-A-00/19149.But this method needs special preparation measures, to prevent that aforesaid liquid is back to fluid supply from closed liquid system, more precisely, be to prevent that under the situation of for example closed liquid system pipe breakage liquid from flowing into from an in fact unrestricted fluid supply, for example public water supply system.
The purpose of this invention is to provide a kind of method, utilize this method, can give the closed liquid system self-feeding from fluid supply as required, and do not have liquid to flow into the danger of fluid supply from this liquid system, in the method, when also guaranteeing disaster or fault to occur in this liquid system, liquid can not flow to the liquid system from fluid supply with not retraining.
A further object of the present invention provides a kind of method, utilizes this method, can give that liquid system is instantaneous to provide predetermined finite quantity liquid.
Another purpose of the present invention provides one and gives conveyer, utilize this can well to realize said method for conveyer, this can automatically carry out supply from a unrestricted substantially source (for example public water supply system) for the leakage of the small amount of liquid the closed circulation loop for conveyer as required, and can not produce the danger of repulsion or unsighted discharge.
Another object of the present invention provides a kind of sealing liquid circulatory system, by adopting above-mentioned to give conveyer, this system can remain under the pressure automatically, and can guarantee simultaneously when taking place to leak, can discharge specific and limited amount liquid at once, so that detect the position of leakage, after discharging this finite quantity liquid, automatic feeding system can not discharged a large amount of water continuously.
By according to provided by the invention as required from the method for fluid supply to the closed liquid system self-feeding, between fluid supply and sealing feed system, form a liquid buffer, and only allow from the feeding buffer liquid to be delivered to this closed liquid system with form dropwise, therefore having guaranteed can be from fluid supply to the feeding continuously of this fluid loop, this method is configured to make and pushes back liquid to liquid buffer and be restricted simultaneously, and does not allow liquid to be back in the fluid supply forever fully.Although this method is also guaranteed in normal running liquid and can be flowed out continuously and do not supervised from fluid supply, but pressure reduces or during pressure fault when (for example when pipe breakage) in fluid loop, more liquid can only spill from fluid supply in the mode of drop, (for example passes through valve) in another way and cut off supply fully when finding.
The feeding buffer can communicate with liquid system, therefore in fact forms the part of this system.Can withstanding pressure under the situation of fluctuation at the feeding buffer, and according to a further advantageous embodiment of the invention, this feeding buffer has minimum volume, and when the pressure in the feeding buffer had surpassed the pressure in the fluid supply, this volume increased.Therefore, the possibility that expands is provided for the feeding buffer, and can be arranged to limit the volume increase of feeding buffer by the unnecessary pressure protect of exhaust.
Because the feeding buffer is only sent liquid according to the mode of drop, therefore in fact obtained effective outflow protection, but the amount of liquid that can join in the system is restricted in the unit interval.In the short period of time a large amount of liquid is delivered in the system if in fact wish, so according to another embodiment of the invention, if a liquid material stock is arranged between feeding buffer and closed liquid system, it connects to come feeding from the feeding buffer by the drop transmission and through opening wide, it is connected with liquid system by closable passage, the opening and closing of this passage are controlled according to the value that closed liquid system produced, thereby can realize above-mentioned requirements.
In order to realize the present invention, a kind of feeding buffer of preferred employing, it is housed in one and gives in the conveyer, this is provided with a cylindrical shell to conveyer, described housing has an inlet, one exports and is arranged on the primary circle column plunger that can move freely in this housing, this plunger be provided with at least the first that is assemblied in by being slidingly matched in this cylindrical shell with and the diameter second portion littler than first, this plunger can seal described outlet at an adjoining position, and clearly stay next tiny leakage pipe, this plunger is provided with a passage that is connected with inlet, and in housing second portion around leave the space, this plunger also is provided with check valve, to prevent getting back to inlet from this spatial flow.Obtaining one by these measures drips to conveyer, wherein under pressure with after a fluid supply (for example public water facilities) is connected, plunger is driven into adjoining position by fluid pressure, and wherein the design of this small leakage pipe makes it only pass through drop according to finite quantity.Therefore can be automatically with supply continuously little ooze out leakage loss.If big disaster takes place, for example pipeline breaking, cause in the outlet pressure fault of dripping to conveyer, this only carries liquid according to the mode of drop for conveyer constantly, thereby also can not make the result of pipeline breaking worsen because a large amount of additive liqs is provided continuously.If opposite situation has taken place, just the pressure in exit is higher than the pressure of porch, for example pressure is temporary transient in supply source reduces or pressure fault, even then the pressure differential between outlet and the inlet raises and the direction and this small leakage pipe that make plunger be pressed towards inlet becomes wideer unlimited connection, but check valve can prevent that also liquid is through this valve and so enter into supply source by inlet.
The realization of minute leakage pipeline with and the maintenance of suitable size and its size etc. depend on the fit system of plunger second portion and outlet.In order to optimize this cooperation, according to still a further embodiment, by being set at the center, a pin shape projection extends the second portion of this plunger, the hole that this projection engages outlet by being slidingly matched forms part, and near with the junction of this second portion a circumferential groove being set, this groove is connected with at least one longitudinal groove along the protruding longitudinal extension of pin shape.By these measures, plunger can be guided in housing exactly, and outlet is reduced to desired size.
Can adopt several different methods to realize this tiny leakage pipe.One of them example can be to form superfine groove in the end wall of the second portion of plunger and shell one or boths' the end surface that matches.But according to still a further embodiment, particularly preferably be, pin shape projection utilizes an end portion to be connected to the plunger second portion, and stop with free end, be provided with sealing ring endways around the part, the free end in the adjoining position of second portion contacts with the cam face of adjusting element, and this is adjusted element and can move with respect to pin shape projection, and when mobile, can be by this pin shape projection mobile plunger along the longitudinal.Can obtain a structure by these measures, utilize this structure can adjust leakiness very exactly, and the width of therefore adjusting the minute leakage pipeline exactly.Just, by plunger the end wall that sealing ring heads on housing is pressed in the sealing station.Adjust element but utilize, plunger can be pushed back, the originally more flat sealing ring of result begins to present once more its round shape gradually.At given time, consequently the sealing ring seals no longer fully, but stays next tiny leakage path.Can control the width of leakage path of acquisition like this and the formation of tiny leakage pipe exactly by adjusting element.
As previously mentioned, in the use of dripping, by plunger being pressed in the adjoining position from the fluid pressure of supply source to conveyer.Even under the situation that temporary transient low pressure or pressure fault in supply source, occur so forever, just plunger is remained on its adjoining position, must apply additional force to plunger towards adjoining position.According to still a further embodiment, if plunger is pressed in the adjoining position by spring, just can be easy to realize this requirement, wherein this spring one end is supported on the plunger, the other end is positioned on the stopping part of fixedlying connected with housing, wherein in this connection, more preferably, this stopping part can be adjusted with respect to housing.
In a kind of comparatively simple mode, according to still a further embodiment, if form check valve by the annular groove in the outer surface of the second portion of plunger, and this groove is provided with lateral edges and bottom, in this groove, have the passage that at least one is communicated with inlet, and the O shape of utilizing adjacency on the lateral edges is encircled and is sealed on the position of distance bottom certain distance, then can obtain a very effective check valve.In addition, by this trenched side-wall is further designed it can be adjusted relative to one another, then can optimally adjust the starting pressure of this check valve, for example under only than the pressure in the slightly higher inlet of the pressure in the space around the second portion, make this check valve open all the time, if the pressure in this space has surpassed the pressure in the porch simultaneously, to guarantee also that then check valve preferably is plugged.And this check valve can be adjusted to higher starting pressure, when the maximum feeding pressure that for example is added in the liquid of fluid circulation system if desired is lower than pressure in the inlet.
In the description in front, point out that because statutory regulation, hope or requirement can not push back the liquid in the fluid circulation system in the supply source, therefore having check valve is a very effective measure.If in this fluid circulation system because undesirable reason (for example overvoltage protection valve fault); in fluid circulation system, form high pressure and make plunger push back a specific range to Way in; then the result is, for example sells the shape projection and can leave its guiding piece.Utilize of the present invention to give conveyer, and according to still a further embodiment, housing is provided with outlet, when the second portion of plunger is in its adjoining position, this outlet by plunger second portion sealed closes, and after Way in moves preset distance, discharge this outlet at plunger, then can preferably realize the release of this system.
The invention still further relates to the firing equipment that is provided with the sealing liquid closed circuit, wherein accommodate at least one boiler and expansion tank, this sealing liquid closed circuit is connected to high pressure liquid source by of the present invention to conveyer.Except great disaster, so can obtain a kind of heating system, it can not become because of lack of water and stop, thereby causes low system pressure and therefore caused the automatic disconnection operation.
In order to detect the leakage in liquid circulation loop, as seen also be very helpful if the amount of liquid of outflow leak makes this leak position become.According to still a further embodiment, communicate if drip to the outlet of conveyer and the supply pipeline that is used for the sealing liquid closed circuit and the inlet that is used for the storage container of make-up water, and this supply pipeline links to each other with supply element inlet, this supply element communicates with liquid circulation loop, described inlet is provided with a valve, this valve is in the closed position usually, but when then being shown in an open position during lack of water in the liquid circulation loop, thereby help to observe leakage.By these measures, in the storage container under the specified pressure, can obtain the liquid of specified quantitative, when opening the valve of supply element, this liquid can be sent in the liquid circulation loop at once.By this liquid pulse, can be so that leak as seen.And this is an instantaneity liquid pulse.If the storage container sky, the supply of this pulse mode stops, and then further supply is only carried out to conveyer by dripping.Therefore can so that the generation of leaking as seen, but can prevent to make the excessive lasting leakage of fluid circulation system by this visual way.
Now with reference to the embodiment shown in the accompanying drawings to illustrating in greater detail for conveyer and heating system according to of the present invention, but just describe in the mode of non-limiting examples.In these accompanying drawings:
