Description
The present invention relates to a kind of by claim 1 multi-way valve that makes the operation of working medium circulation safe as described in the preamble.
The necessary energy of working medium circulation safe operation (regular work state) in process automation or the power generating equipment, and possible fault (informal working state) must be able to reliably be controlled in running.Especially for situation about sewing in the working medium circulation, its consequence may cause the working medium loss, must guarantee that device security turn-offs.
Therefore the objective of the invention is, a kind of multi-way valve that described requirement is used for the working medium circulation that satisfies can be provided.
This purpose reaches by the multi-way valve that makes the operation of working medium circulation safe with claim 1 feature.Comprise import by multi-way valve of the present invention, the first and second outlet and conversion equipments, wherein, the gas volume of pressurization is provided in inlet, and first outlet can be connected with the hot branch line of working medium circulation, the second outlet can be connected with the cold branch line of working medium circulation, and wherein, conversion equipment is designed to, close import at the regular work state, and open import in informal working state, and can or go to the first outlet or go to the second outlet at the gas volume that inlet provides, this depends on that outlet port exists compares lower pressure with another outlet.
Especially when one of two branch lines that are attached thereto, when also instant heating or cold branch line are sewed, cause two obvious pressure reduction in outlet port.Here, hot branch line should be regarded as working medium circulation from source point, process source or the energy branch line of drawing for example, and cold branch line then is the branch line of guiding described source point into.Owing in the cold or hot branch line of working medium circulation, sewing, cause opening closed so far circulation towards the surrounding environment direction, thereby working medium can be overflowed.Because working medium pressure all is higher than external pressure in the ordinary course of things, so at first cause local compression to descend sewing the place.Then this pressure drop expands to whole working medium circulation gradually.
By multi-way valve of the present invention, it is connected an outlet with hot branch line, and another outlet is connected with cold branch line, now might with the gas volume that provides from the multi-way valve adding have sew also thereby that branch line of local compression decline in.In case the pressure of the gas volume that provides greater than the pressure in the branch line of sewing, is just connected by multi-way valve of the present invention, the gas from gas volume can be flowed in this branch line.Because the gas expansion that flows into squeezes the working medium in this branch line that can sew, and also by sewing outflow.The flux density of impelling thus obvious reduction working medium to flow out causes significantly reducing the loss of working medium.
Therefore depend on the gas volume of existence and the degree of sewing, even in informal working state, the operation of equipment still can be kept some times, and do not cause equipment to be in runaway condition this moment.Exactly, exist possibility at this moment between during device security close, and can take to guarantee other follow-ups of device security.
For the gas from gas volume can be circulated by flowing into working medium by multi-way valve of the present invention, the pressure in the gas volume must have the value of predesignating.According to the application of equipment or purpose and the security requirement that should observe, the pressure of gas volume must suitably be selected.Importantly, be identified in immediately the local pressure drop that occurs in one of branch line, and in case in this branch line described pressure drop, still compare corresponding to the pressure of working pressure all the time with the inertia regular hour after sewing based on working medium, reach the pressure reduction that certain is predesignated, multi-way valve is just made a response, and making gas flow into this has in the branch line of sewing.
Especially may importantly not only stoping when informal work because leakage flow goes out working medium in electricity generating device, here is freezing mixture, and the other working medium of continuous supplementation input.This reaches by establishing the second import by the present invention, the working medium storage volumes of pressurization is provided in the second inlet, wherein, described the second import is closed by conversion equipment at the regular work state, and in informal working state, in the working medium storage volumes that the second inlet provides, can or go to the second outlet or go to the first outlet, this will see in that outlet port existence and compare higher pressure with another outlet.Therefore this multi-way valve provides the working medium of additional deposit by its second import, and it adds in that branch line of not sewing when informal work.Therefore can simultaneously gas volume be added in the branch line that can sew and sew for " sealing ", and additional working medium is added in the working medium circulation, be used for the working medium that " replenishing " fallen owing to leadkage loss.
Particularly preferably be, by multi-way valve of the present invention conversion equipment arranged, it can be according to the pressure reduction between the multi-way valve outlet, the inflection point the when position of rest during from the regular work state moves to informal working state.Do not need thus other control systems, because multi-way valve independently recognizes whether there is pressure reduction in the outlet port and takes appropriate measures based on the configuration of conversion equipment.Here appropriate is to establish biased member or pre-tightening apparatus, and it reliably and stably is fixed on its position of rest with conversion equipment, and the value of predesignating for permissible pressure when determining the regular work state by the power of pre-tightening apparatus.
In order to obtain a kind of also simple especially thereby favourable form of implementation of multi-way valve, conversion equipment is rotatably mounted and be set to, to be divided into two subregions that are isolated from each other in order to rotate necessary cavity in the multi-way valve, these two subregions are attached troops to a unit respectively in an outlet.Therefore the pressure that occurs in the outlet port also is present in these two subregions, and thereby acts directly on the described rotatable conversion equipment.
When specific design, pre-tightening apparatus is comprised of the spring material, the revolving point of they and conversion equipment staggers and acts on the conversion equipment from two opposed minute chambeies, make conversion equipment when regular work, be fixed on position of rest, and thereby close the first import or the first and second import.Can establish in addition especially can the electromagnetism release lockset, they are fixed on conversion equipment on the position after the informal working state deflection.
Can be applied to especially satisfy the highest security requirement by multi-way valve of the present invention, the working medium in the initial cycle of equipment electricity generating device is when especially freezing mixture lacks, in the situation that informal working state is kept the working medium circulation of power generating equipment.
For reach the preparation of described purpose by equipment electricity generating device of the present invention, except the energy, power consumption point (energy sink), have the hot branch line and the working medium circulation from the power consumption point to the cold branch line of the energy from the energy to power consumption point, the multi-way valve that also has the front to illustrate, multi-way valve is configured such that its first outlet is connected with hot branch line, and its second outlet is connected with cold branch line.
Special in must satisfying the nuclear industry equipment of highest security requirement, by the present invention multi-way valve is set in electricity generating device, multi-way valve is provided for, electricity generating device can and be moved under informal working state at the regular work state that is used for generating, under informal working state, must be able to control the coolant loss in the initial cycle.
For can be independent of that external control devices implements electricity generating device these by safety measure of the present invention, can connect in the first import of multi-way valve the gas pressure vessel of in advance filling, and the water storage volumes that connects pressurization in the second import.Thus, in case multi-way valve is made a response, just provide immediately two safety measures, needn't take other measures, open additional valve such as control.
Therefore the present invention can be widely used in those operation has the place of highest security requirement for equipment, can be power generating equipment, for example steam power station, combustion gas and steam power station or nuclear industry power station, or also can be process automation equipment.
The below should illustrate the present invention by accompanying drawing.Wherein:
Fig. 1 is illustrated in the working medium circulation by multi-way valve basic principle of the present invention;
Fig. 2 schematically illustrates the multi-way valve that an import is arranged by a kind of form of implementation of the present invention; And
Fig. 3 schematically illustrates the multi-way valve that two imports are arranged by the another kind of form of implementation of the present invention.
Now should at first illustrate by multi-way valve basic principle of the present invention by the basic structure that represents among Fig. 1.Diagram multi-way valve V has import E1 and the first outlet A1 and the second outlet A2.Described multi-way valve V can be connected with the working medium circulation.Can see this working medium circulation in various process automation equipment and power generating equipment, wherein, at least basically closed circulation, working medium must be at the energy or the process energy and the circle transmission energy between point or the process power consumption point that consumes energy.Some that the segmentation summary represents described circulation among Fig. 1 are for explanation part and parcel of the present invention." hot branch line " H as seen from the figure, that is in the circulation working medium is transported to the part of power consumption point from source point, and " cold branch line " K, it is carried working medium and gets back to source point from the power consumption point.The arrow that with dashed lines is drawn in Fig. 1 represents described circulation.
Circulate also thereby the knotty problem of whole equipment safety operation aspect as working medium, already proved following situation may occur, that is in circulating, sew and the working medium effusion, for example break down or even interruption from the continuous transmission of the energy of the energy this moment.Therefore establish conversion equipment U by the present invention in multi-way valve V, it is connected to each other two kinds of functions.Conversion equipment U design here also is configured in valve V, at first in the ordinary course of things, and at the import E1 corresponding to the first working state cut-off valve V of regular work state.Otherwise in the informal working state of equipment, that is in the working state that does not conform to the regular work state, conversion equipment allows to open import E1, and the gas volume G that offers import E1, or guides the first outlet A1 of valve V into, or guides the second outlet A2 of valve V into.Here, which the gas volume G that offers import E1 place guides among outlet A1 or the A2 into, depends on which compares the lower pressure of existence in these outlets with another outlet.That is to say, if the hot branch line H of outlet A1 and A2 and working medium circulation be connected branch line K and be connected, and one of two branch lines have occured to sew also thereby have caused the pressure loss, then thisly sew that the short time also can be caused pressure reduction between A1 and A2 at least.Surpass specified value if locate this pressure reduction at one of A1 or A2 now, then conversion equipment U opens import E1 in valve V, and meanwhile the gas G that provides is guided towards that Way out that lower pressure is arranged, thereby gas G can be flowed in the connected branch line there.If the pressure of inflow gas G is higher than the pressure of working medium in this branch line now, then enter the gas G expansion in this branch line, and thereby impact type expand and squeeze thus working medium.So the working medium of sewing is also squeezed, and thereby stop working medium further to flow out and further loss.Even therefore equipment can also continue to move at least a period of time again under this informal working state.If this situation for example causes breaking down, then keep certain hour, so that safety shutdown devices or take other measures in power generating equipment.
Fig. 2 schematically illustrate in the power generating equipment initial cycle, use by the multi-way valve V of the present invention form of implementation that can imagine.Here, initial cycle comprises for example pressurized water reactor container, steam generator and hot and cold branch line.In hot branch line, the current direction steam generator that in reactor vessel, heats.Then, cooled water in steam generator flow back in the steam generator by pump in cold branch line again as cold water, thereby forms closed circulate coolant.
Now by the present invention by the two-way valve that represents among Fig. 2 or two-way valve V, guide gas G into outlet A1 or A2, and thereby the branch line that is attached thereto respectively of guiding, in this branch line, cause the pressure loss based on sewing in advance.Utilize physical effect here, that is in one of branch line based on the freezing mixture decompression wave of sewing generation, time lag, ground arrived the different location of circulation, so that namely cause at least two pressure reduction between branch line and therefore cause valve V conversion equipment U correspondingly to move after sewing.The gas G of pressurization flows into by valve V to be had in the branch line of sewing, and impact type expands there, so at this point squeeze freezing mixture also thereby significantly reduce freezing mixture and cause further mass loss because sewing.Therefore, under this failure condition, freezing mixture can provide use the long period in initial cycle.
By the form of implementation that Fig. 2 represents, valve V has can be around the conversion equipment U of revolving point UD swivel bearing.Described conversion equipment U here is designed to, and it is divided into two subregion T1 and T2 with the cavity that moves therein for conversion equipment U in the multi-way valve.As representing among the figure, this point reaches by the beam shape design of conversion equipment U, and this conversion equipment asymmetricly supports in addition.Wherein the first subregion T1, that is the first partial volume attaches troops to a unit in the first outlet A1, and the second subregion T2(the second partial volume) attach troops to a unit in the second outlet A2.The state that multi-way valve represents in Fig. 2 relates to the regular work state of equipment, and the import E1 of multi-way valve was converted device U and itself closed this moment.Under this situation, movable conversion equipment U is in position of rest, and described position of rest can take the measure that adds to strengthen, and for example applies bias voltage or pretension and interactional spring D1 and D2 by expression here.Even therefore there is the less pressure surge that is lower than threshold value, can not cause conversion equipment U motion also yet thereby make its deflection.
Now the situation of hypothesis is, in the situation that occur sewing in the hot branch line that breaks down, and this branch line is connected with the outlet A1 of multi-way valve, thereby at first causes pressure drop also at this outlet A1 place thereby cause two to export between A1 and the A2 and produce pressure reduction.Because these two outlets also are connected with T2 with subregion T1 respectively, so described pressure reduction also is present in the both sides of conversion equipment U.If the pressure reduction between present two subregion T1 and the T2 surpasses the value (for example 5 to 6bar) of predesignating, this value of predesignating is based on two preloading spring D1 that select and the elasticity of D2 and inertia or the inertia adjustment of conversion equipment, so cause conversion equipment U to rotatablely move and thereby it is gone out from position of rest deflection.Among the embodiment of expression, when in hot branch line, sewing, based on pressure lower in the subregion T1 that causes thus and the asymmetrical eccentric support of conversion equipment, cause conversion equipment U clockwise direction to rotate here.Therefore conversion equipment U moves towards the direction of subregion T2 side S2, and the import E1 that stops up before discharging thus.From the superheated steam of gas volume G, can flow to outlet A1 through subregion T1 from import E1 now, and flow into therefrom hot branch line.Additional lockset R1 and R2 are used for fixed conversion device U here and also thereby with it stably are bearing in a position after the deflection.As shown in Figure 2, for example again electromagnetism release of lockset R1 and R2.Conversion equipment can come back to it for the position of rest of equipment normal operation for later normal mode of operation thus.
Otherwise if, if in cold branch line, also thereby at outlet A2 place cause pressure drop, then conversion equipment U makes corresponding reaction, and based on pressure lower in the subregion T2 and the geometry designs of supporting, here counterclockwise move towards the direction of side S1, thereby gas G can flow to outlet A2 from import E1, and thereby flows in the cold branch line.
By the function of multi-way valve of the present invention thereby can be only by the 5-6bar pressure reduction Passive Control of for example predesignating in outlet A1 and the existence of A2 place, and thereby can not take other the exterior measures.But the measure that does not have expression here that also can take to add is for example established pressure valve in import between gas volume G and import E1, these measures do not affect by multi-way valve of the present invention function described above.
Fig. 3 represents by valve V another kind of the present invention wherein to take other additional measures by form of implementation of the present invention.The multi-way valve that represents among the figure also has the second import E2 except the first import E1.Can provide the additional working medium volume W for preparing for informal working state by described the second import E2.Here the four way valve of expression or four-way valve V might be simultaneously add the gas from gas volume G in the branch line of sewing by import E1, and additional working medium W is added working medium by import E2 circulate in another branch line of not sewing.The adding of additional work medium W here can initiatively be carried out by additional pump (not shown), or the only passive realization of volume by pressurizeing as representing among Fig. 3.
Adopt form of implementation shown in Figure 3 still to utilize described physical effect, input leakage branch line and a small amount of gas that expands there just have been enough to significantly reduce the mass flow rate of working medium by sewing, and thereby prolong the time of controlledly closing for equipment.But here, for example in nuclear industry equipment, also add in another branch line by simultaneously gas being added in the branch line and with additional freezing mixture, reach the secondary cooling of reactor with the longer time.
The fundamental function of four-way valve shown in Figure 3 is consistent by the embodiment that Fig. 2 has illustrated with the front to a great extent.Suppose in hot branch line H, to sew, then in this branch line, also thereby also locate pressure drop at valve V outlet A1 and subregion T1 '.By the asymmetric supporting of beam shape conversion equipment U, cause conversion equipment U to clockwise rotate here.Along with described rotation, conversion equipment U is towards the motion of the direction of side S2 and thereby discharge two import E1 and E2.Gas at import E1 place from gas volume G can flow to outlet A1 by subregion T1 and connecting passage now, and at import E2 place the additional work medium from working medium storage volumes W, can export A2 by the subregion T2 ' flow direction.Here in the represented example, be used for spring D1 and D2 and lockset R1 and the R2 of pretension conversion equipment, with example illustrated in fig. 2 identical function arranged.
The invention is not restricted to form of implementation described above.Exactly, also can consider combination, the change or additional of various features, these should be able to cause other the possible forms of implementation by inventive concept.For example replace the rotary converter that represents above, also can in valve, establish the horizontal moving type conversion equipment.Replace the spring that schematically illustrates, also can adopt the elastic element of any other type, as long as they have and the identical characteristics that illustrate previously.Although the front only has been used as detailed description for making in the power generating equipment with the energy and power consumption point in description of drawings, the present invention also can be applied in all that and be fit to avoid the occasion that causes the unmanageable fault of equipment of sewing in the working medium circulation.
