Description

151515151515

Opfindelsen angår en reguleringsmekanisme til varmeveksleranlæg af den i hovedkravets indledning angivne art.The invention relates to a control mechanism for heat exchanger systems of the kind specified in the preamble of the main claim.

I varme/køleanlæg er der sædvanligvis monteret en shuntventil for at skille varme/kølesiden fra forbrugersiden og for at give mu-5 lighed for regulering.In heating / cooling systems, a shunt valve is usually fitted to separate the heat / cooling side from the consumer side and to allow for regulation.

Som oftest er shuntventilen indbygget i anlægget i en såkaldt shuntkobling, som principielt er vist i fig. 1. Ledningssystemet på shuntkoblingens forrådsside (for varme eller kulde) kaldes sædvanligvis primærkredsen og på koblingens forbrugerside sekundærkredsen.Most often, the shunt valve is built into the system in a so-called shunt coupling, which is shown in principle in FIG. 1. The wiring system on the supply side of the shunt coupling (for hot or cold) is usually called the primary circuit and on the consumer side of the coupling the secondary circuit.

10 Den sidstnævnte kan omfatte et større antal forbrugere, og trevejsventilen drives af en termostatstyret motor i overensstemmelse med varme/kuldebehovet i sekundærkredsen.The latter may comprise a greater number of consumers and the three-way valve is operated by a thermostatically controlled motor according to the heat / cold requirements of the secondary circuit.

Når der ikke er behov for varme/kulde i sekundærkredsen, skal trevejsventilen være lukket, og der skal da ikke være nogen I5 cirkulation i ledningssystemet mellem primærkredsen og sekundærkredsen. Det har vist sig, at en shuntkobling med kun en trevejsventil ikke er tilstrækkelig til at forhindre varmetab, som skyldes strømningslækager mellem kredsene. Fig. 1 viser et eksempel på utilsigtet cirkulation i en shuntkobling. For at undgå utilsigtet cirkulation, som 20 resulterer i store varmetab, kan man anbringe en yderligere lukkemekanisme i shuntkoblingens kreds. En sådan lukkemekanisme kan være i form af en motordrevet lukkeventil, magnetisk ventil, kontraventil, U-rør med væskélås og andet. Ulempen med sådanne yderligere lukkemekanismer er, at de foruden at fordyre anlægget og komplicere kon-25 struktionen også kræver individuel betjening, da de sædvanligvis ikke skal deltage i normal reguleringsdrift, fordi reguleringsfunktionen er tillagt trevejsventilen. Dertil kommer, at hver yderligere ventil eller lukkemekanisme, som indkobles i systemet, udgør en ny støjkilde.When there is no need for heat / cold in the secondary circuit, the three-way valve must be closed and there should then be no I5 circulation in the wiring system between the primary circuit and the secondary circuit. It has been found that a shunt coupling with only a three-way valve is not sufficient to prevent heat loss caused by flow leaks between the circuits. FIG. 1 shows an example of accidental circulation in a shunt coupling. In order to avoid accidental circulation which results in large heat losses, an additional closing mechanism can be placed in the shunt coupling circuit. Such a closing mechanism may be in the form of a motor-operated closing valve, magnetic valve, non-return valve, U-tube with fluid lock and other. The disadvantage of such additional closing mechanisms is that, in addition to costing the plant and complicating the construction, they also require individual operation, as they usually do not have to participate in normal control operation because the control function is assigned to the three-way valve. In addition, each additional valve or closure mechanism that is connected to the system constitutes a new source of noise.

Forudsætningen for reguleringsdriften er, at mediet i primær-30 kredsen og i sekundærkredsen cirkulerer, og disse kredse er derfor forsynet med hver sin cirkulationspumpe. Foruden pumper kan anlægget have yderligere lukkeventiler, drøvleventiler, haner, termometre o.s.v.. Nogle af dem kan også være anbragt indenfor shuntkob-lingen mellem fremløbsledningen og returledningen på primærsiden 35 eller sekundærsiden.The prerequisite for the control operation is that the medium circulates in the primary circuit and in the secondary circuit, and these circuits are therefore equipped with a separate circulation pump. In addition to pumps, the system may have additional shut-off valves, throttle valves, taps, thermometers, etc. Some of them may also be located within the shunt connection between the supply line and the return line on the primary side 35 or the secondary side.

Formålet med opfindelsen er at tilvejebringe en reguleringsmekanisme (i det følgende kaldt ventilmekanisme), som ikke alene har 151515 2 stilling sikrer anlægget mod uforudsete strømningslækager mellem primærkredsen og sekundærkredsen. Et andet formål med opfindelsen er at tilvejebringe en reguleringsmekanisme af den nævnte art, som lader sig bygge som en kompakt enhed, der er let at montere, og som fylder 5 forholdsvis lidt.The object of the invention is to provide a regulating mechanism (hereinafter called valve mechanism) which not only has the position of securing the plant against unforeseen flow leaks between the primary circuit and the secondary circuit. Another object of the invention is to provide a regulating mechanism of the kind which can be built as a compact unit which is easy to assemble and which fills relatively little.

Denne opgave løses ifølge opfindelsen ved, at lukke/åbne- og reguleringsmekanismen er udformet med de i krav l's kendetegnende del angivne ejendommeligheder. Ved denne udformning af lukke/åbne- og reguleringsmekanismen opnås ved hjælp af et eneste regulerings- og 10 lukkeorgan både en nøjagtig og pålidelig regulering af vandstrømmen og en absolut sikker og effektiv lukning og god varmestrømningsmæssig isolering mellem primærsiden og sekundærsiden i den lukkede tilstand. Foruden den effektive og varmeisolerende afspærring mellem fremløbets primærside og sekundærside (stempelsiden kan være af et formstofma-15 teriale, som er meget varmeisolerende) opnås i den afspærrede tilstand også en forbindelse mellem fremløbet og returløbet på sekundærsiden og dermed en temperaturudligning (i hviletilstanden), som sikrer mod støj forårsaget af varmeudvidelser eller varmesammentrækning på grund af ujævne temperaturovergange.This task is solved according to the invention in that the closing / opening and regulating mechanism is designed with the characteristics specified in the characteristic part of claim 1. In this design of the closing / opening and regulating mechanism, by means of a single regulating and closing means, both accurate and reliable regulation of the water flow and an absolutely safe and effective closure and good heat flow insulation between the primary and secondary sides in the closed state are achieved. In addition to the effective and heat insulating barrier between the primary and secondary side of the flow (the piston side can be of a material which is very heat insulating), in the closed state a connection is also obtained between the flow and the return flow on the secondary side, and thus a temperature equalization (in the resting state), which protects against noise caused by heat expansion or heat contraction due to uneven temperature transitions.

20 Opfindelsen skal herefter forklares nærmere ved hjælp af eksempler under henvisning til tegningen og i forbindelse med et varmeanlæg, men det vil forstås, at opfindelsen er lige så godt anvendelig ved køleanlæg (f.eks. med isvand som kølemedium).The invention will then be explained in more detail by way of examples with reference to the drawing and in connection with a heating system, but it will be understood that the invention is equally applicable to cooling systems (eg with ice water as a cooling medium).

På tegningen viser: 25 fig. 1 den indledningsvis omtalte shuntkobling mellem et varme anlægs primærkreds og sekundærkreds, fig. 2 skematisk og delvis i snit en udførelsesform for reguleringsmekanismen ifølge opfindelsen, fig. 3 i udfoldning porte til en stempelglider med en alternativ 30 udførelse, fig. 4 en alternativ udførelse af et grenkanalparti og stempelgliderens endeparti og et tilstødende parti af en anden samvirkende kanal, fig. 5 en anden alternativ udførelsesform for det samme parti, 35 og fig. 6 et billede svarende til fig. 1, men til illustrering af en udførelsesform for mekanismen ifølge opfindelsen.In the drawing: FIG. 1 shows the shunt coupling initially mentioned between a primary system's secondary circuit and a secondary circuit; FIG. 2 is a schematic and partial sectional view of one embodiment of the control mechanism according to the invention; FIG. 3 in unfolding ports for a piston slide having an alternative embodiment; FIG. 4 shows an alternative embodiment of a branch channel portion and the end portion of the piston slide and an adjacent portion of another cooperating channel; FIG. 5 shows another alternative embodiment of the same portion, 35 and FIG. 6 is a view similar to FIG. 1, but to illustrate one embodiment of the mechanism of the invention.

Fig. 1 illustrerer utilsigtet cirkulation i en skematisk vist shuntkobling af kendt udformning. Primærsiden er betegnet med P, sekundærsiden med S, fremløbsledninger med T og returledninger med R og en trevejsventil med V. Ventilen drives fra en termostatstyret motor 5 M. Til trods for lukket ventil opstår der lækagestrømme og lækagecirku lation ved koblingspartiet, som er mærket L, med det resultat, at der aldrig vil blive ligevægtsindstilling i primærkredsen, hvilket medfører kontinuerligt varmetab.FIG. 1 illustrates inadvertent circulation in a schematically shown shunt coupling of known design. The primary side is designated P, the secondary side with S, flow lines with T and return lines with R and a three-way valve with V. The valve is operated from a thermostatically controlled motor 5 M. Despite closed valve, leakage currents and leakage circulation occur at the coupling section marked L , with the result that there will never be equilibrium adjustment in the primary circuit, resulting in continuous heat loss.

Fig. 2 viser skematisk en udførelsesform for ventilmekanismen 10 eller reguleringsmekanismen ifølge opfindelsen med et ventilorgan, som ikke alene udfører reguleringsventilens funktion (trevejsventilen V) i shuntkoblingen ifølge fig. 1, men som også medfører fuldstændig strømningsmæssig aflukning mellem sekundærkredsen og primær kredsen, når ventilorganet først er bragt i lukkestilling.FIG. 2 schematically shows an embodiment of the valve mechanism 10 or the control mechanism according to the invention with a valve means which not only performs the function of the control valve (three-way valve V) in the shunt coupling according to FIG. 1, but which also causes complete flow closure between the secondary circuit and the primary circuit when the valve means is first brought into the closing position.

15 Et rørstykke 1 og et rørstykke 4 er anbragt parallelt med og i lille afstand fra hinanden. Ved et sted mellem rørstykkerne 1 og 4's ender forløber der et stempelgliderrør 7, og dette deler røret 1 i to rørstykker 2 og 3 og røret 4 i to rørstykker 5 og 6, som parvis befinder sig på hver sin side af røret 7. Rørene 1, 4 og 7 ligger i samme 20 plan, og røret 7 har større diameter end rørene 1 og 2. Røret 7's ene endeparti 8 rager et kort stykke udenfor røret 4 og er lukket med en bund, medens røret 7's andet endeparti 10 er væsentligt længere og er åbent ved sin ende, som er lukket med en forskruning 11 med en boring 12, der er forsynet med ringtætninger 13 for gennemføring 25 af en stempelstang 14, som både kan forskydes aksialt og drejes i boringen 12.A pipe piece 1 and a pipe piece 4 are arranged parallel to and at a small distance from each other. At a point between the ends of the tubes 1 and 4, a piston sliding tube 7 proceeds, and this divides the tube 1 into two tubes 2 and 3 and the tube 4 into two tubes 5 and 6, which are in pairs on each side of the tube 7. The tubes 1 , 4 and 7 lie in the same plane 20 and the tube 7 is larger in diameter than the tubes 1 and 2. The one end portion 8 of the tube 7 projects a short distance outside the tube 4 and is closed with a bottom, while the other end portion 10 of the tube 7 is substantially longer. and is open at its end, which is closed with a socket 11 with a bore 12 provided with ring seals 13 for passage 25 of a piston rod 14 which can be both axially displaced and rotated in the bore 12.

I praksis er rørkonstruktionen sammensvejset af rørstykker, og rørstykket 2 udmunder i røret 7 med sin åbning 15. Røret 3 har en tilsvarende åbning 16, medens røret 5 og 6 har en åbning, hen-30 holdsvis 17 og 18. Et skrårør 19 med omtrent samme diameter som røret 5 forløber mellem rørstykket 5 og et sted på stempelgliderrøret 7 omtrent midt mellem rørene 3 og 4. Crenrøret 19 forbinder røret 5 med røret 7 gennem åbninger 20 og 21. På røret 19 er der svejset en vorte 22 for eventuel udboring for anbringelse af en hane, drøvleventil, 35 lukkeventil eller lignende. Et forbindelsesrør 23 strækker sig mellem rørstykkerne 2 og 4 og forbinder disse med hinanden. Rørstykket 23 er på midten forsynet med en hane 24 eller en lukkeventil.In practice, the pipe structure is welded by pipe pieces, and pipe piece 2 opens into pipe 7 with its opening 15. The pipe 3 has a corresponding opening 16, while the pipes 5 and 6 have an opening, respectively 17 and 18. A cutting pipe 19 with approx. the same diameter as the pipe 5 extends between the pipe piece 5 and a location on the piston sliding pipe 7 approximately midway between the pipes 3 and 4. The pipe 19 connects the pipe 5 with the pipe 7 through openings 20 and 21. On the pipe 19 a wart 22 is provided for possible drilling for placement of a tap, throttle valve, 35 shut-off valve or the like. A connecting pipe 23 extends between the pipe pieces 2 and 4 and connects them to each other. The pipe piece 23 is provided in the center with a tap 24 or a shut-off valve.

4 151515 I gliderrøret 7 er der drejeligt og forskydeligt anbragt en stempelglider 25, der er stift forbundet med stempelstangen 14. Glideren har et lukket endeparti 26, som, når glideren befinder sig i lukkestilling (yderst til venstre i fig. 2), strækker sig omtrent fra bunden 5 af rørforlængelsen 8 og til et sted i lille afstand fra kanten af åb ningen 11. Stempelstangen 14 er fastgjort i denne kompakte del af stempelglideren. Det resterende parti 27 af stempelglideren er udformet som et rør med åben ende på stempelstangsiden, og i den nævnte stilling strækker det sig et lille stykke forbi kanten af åbnin-10 gen 15 eller 16 i røret, henholdsvis 2 og 3 som vist i fig. 2.In the slider tube 7 a piston slider 25 is pivotally and slidably mounted rigidly connected to the piston rod 14. The slider has a closed end portion 26 which, when the slider is in the closing position (far left in Fig. 2), extends approximately from the bottom 5 of the tube extension 8 and to a location at a small distance from the edge of the opening 11. The piston rod 14 is secured in this compact portion of the piston slide. The remaining portion 27 of the piston slide is formed as an open end tube on the piston rod side, and in said position extends a short distance beyond the edge of the opening 15 or 16 of the tube, 2 and 3, respectively, as shown in FIG. 2nd

Glideren 25 eller rettere sagt gliderens rørformede del 27 er udformet med fra et til tre sæt porte 28,29 og 30. Fig. 4 viser glider-fladen i udfoldning med tre sæt porte. Til udførelsesformen ifølge fig.2 er gliderfladen afmærket med A,B,C,D. Portsættet 28 omfatter tre af-15 lange rektangulære porte, som samvirker enkeltvis med rørstykket 3's åbning 16. Portsættet 29 omfatter tre kileformede eller trekantformede porte, som er anbragt diametralt modsat de førstnævnte porte, og som samvirker med rørstykket 2's åbning 15. Portene er stærkt tilspidset i stempelgliderens åbneretning for opnåelse af finreguleret gennemstrøm-20 ning. Portsættet 30 omfatter tre trekantformede porte, som er anbragt på omtrent samme frembringere som portsættet 28's porte. Portene til portsættet 30 vender deres spidser i gliderens lukkeretning. Som vist i fig. 2 har portene 28 en sådan længde, at de er i forbindelse med rørstykket 3's åbning 16 uanset stempelgliderens stilling. Portene 25 30 har fuld åbning, når de befinder sig lige overfor grenrørets åb ning 21. I den sidstnævnte stilling befinder portene 29 sig uden for området for åbningen 15 i rørstykket 2. Portene 29 har fuld åbning, når stempelglideren befinder sig i åbnestillingen. Stempelgliderens lukkede endeparti 26 tjener til gradvis åbning og lukning af åbninger-30 ne 17 og 18 i rørstykkerne, henholdsvis 5 og 6.The slider 25 or rather the tubular portion 27 of the slider is formed with from one to three sets of ports 28,29 and 30. FIG. 4 shows the sliding surface unfolding with three sets of gates. For the embodiment of Fig. 2, the sliding surface is marked with A, B, C, D. The gate set 28 comprises three of 15 long rectangular gates which cooperate individually with the opening of the pipe piece 3. tapered in the open direction of the piston slide to achieve finely regulated flow. The gate set 30 comprises three triangular gates which are arranged on approximately the same generators as the gates of the gate set 28. The gates of the gate set 30 turn their tips in the slider's closing direction. As shown in FIG. 2, the ports 28 are such that they are in communication with the opening 16 of the pipe piece 3 regardless of the position of the piston slide. The ports 25 30 have full opening when they are directly opposite the opening of the manifold 21. In the latter position, the ports 29 are outside the area of the opening 15 of the pipe piece 2. The ports 29 have full opening when the piston slider is in the open position. The closed end portion 26 of the piston slide serves to gradually open and close the openings 30 and 17 of the pipe sections 5 and 6, respectively.

Fig. 2 viser som nævnt ventilmekanismen i lukket stilling. Det kan antages, at røret 1 tilhører fremløbsledningen og røret 4 returledningen, således at rørstykkerne 2 og 4 tilhører primærkredsen, og rørstykkerne 3 og 5 tilhører sekundærkredsen. Endvidere antages det, 35 at hanen 25 er åben. Når stempelglideren befinder sig i den nævnte stilling, er fremløbet blokeret ved 15 og returløbet ved 17 og 18. Der er forbindelse mellem løbet 5 og løbet 3 gennem grenløbet 19, en af por- 5 151515 tene 30, gliderens indre og en af portene 28. Sekundærkredsen er således hydraulisk isoleret fra primærkredsen. I primærkredsen er der forbindelse mellem fremløbet 2 og returløbet 6. Eventuelt kan hanen 24 lukkes ved specielle anlæg. Anbringelsen af hanen er imid-5 lertid ikke væsentlig for denne opfindelse, og det samme gælder rørstykket 23. Deres tilstedeværelse i mekanismen forøger imidlertid væsentligt mulighederne for brugeren af mekanismen i forskellige reguleringssystemer.FIG. 2, as mentioned, shows the valve mechanism in the closed position. It can be assumed that the pipe 1 belongs to the supply line and the pipe 4 the return line, so that the pipe pieces 2 and 4 belong to the primary circuit and the pipe pieces 3 and 5 belong to the secondary circuit. Furthermore, it is assumed that the male 25 is open. When the piston slide is in said position, the flow is blocked at 15 and the return flow at 17 and 18. There is a connection between the run 5 and the run 3 through the branch run 19, one of the ports 30, the interior of the slider and one of the gates 28 Thus, the secondary circuit is hydraulically isolated from the primary circuit. In the primary circuit there is a connection between the flow 2 and the return flow 6. Optionally the tap 24 can be closed at special plants. However, the positioning of the tap is not essential to this invention, and the same is true of the pipe piece 23. Their presence in the mechanism, however, significantly increases the possibilities for the user of the mechanism in various control systems.

Når stempel g I ide ren bevæges til åbnestilling, d.v.s. til højre i 10 fig. 2, vil porten 29 blive åbnet gradvis, og porten 21 vil blive lukket gradvis, samtidig med at forbindelsen mellem røråbningerne 17 og 18 vil åbnes forholdsvis hurtigt. Gennemstrømningen reguleres med aksialforskydning af stempelglideren og tilvejebringes ved hjælp af stempelstangen 14, der er koblet til en motordrevet mekanisme, som 15 alene forskyder glideren aksialt; Ved at dreje stempelglideren manuelt kan man vælge ventilens kapacitet og reguleringsevne ved valg af portene i de tre portsæt 28, 30 og 29. Den drejelige vælgermekanisme for portstørrelsen gør koblingsmekanismen meget anvendelig.When the plunger g is moved to the open position, i.e. to the right in FIG. 2, the gate 29 will be opened gradually and the gate 21 will be closed gradually, while the connection between the pipe openings 17 and 18 will be opened relatively quickly. The flow is controlled by axial displacement of the piston slide and provided by the piston rod 14 coupled to a motor-driven mechanism which 15 alone displaces the slide axially; By manually rotating the piston slide, one can select the valve capacity and regulating ability when selecting the ports in the three port sets 28, 30 and 29. The swivel selector mechanism for the gate size makes the clutch mechanism very useful.

Fig. 4 viser en anden udførelsesform for stempelglideren 125's 20 endeparti 126 på det tilsluttede parti af koblingsmekanismen. Der er anvendt samme henvisningsbetegnelser for delene som i fig. 2, men forøget med 100. Som vist er rørløbet 105 ført ind på skrå i gliderrøret 107 parallelt med grenløbet 119. Det andet rørløb 106 er ført et stykke forbi gliderrøret 107's akse, og gliderrøret 107's endeparti, 25 som her udmunder i røret 106, er udformet som et kegleformet ventilsæde 108. Stempelgliderens endeparti 126 er udformet med en endekegle, der samvirker med sædet. På denne måde opnås der en tættere aflukning og en jævnere åbning for mediumstrømmen gennem rørene 105 og 106.FIG. 4 shows another embodiment of the end portion 126 of the piston slide 125 20 on the connected portion of the coupling mechanism. The same reference numerals have been used for the parts as in FIG. 2, but increased by 100. As shown, the tubing 105 is inserted obliquely into the slider 107 parallel to the branch 119. The second tubular 106 is passed a distance past the axis of the slider 107, and the end portion of the slider 107, which here opens into the tube 106, is configured as a cone-shaped valve seat 108. The end portion 126 of the piston slide is formed with an end cone that cooperates with the seat. In this way, a closer closure and a smoother opening for the medium flow is obtained through pipes 105 and 106.

30 Fig. 5 viser endnu en udførelsesform, hvor gliderrøret 207 er forlænget betydeligt udenfor rørene 205 og 206, således at der er dannet en rørføring 208 til stempelgliderens forlængelse 226. Denne forlængelse er forsynet med et sæt porte 240, der er vist i planet A,D,E,F i fig. 3. I begge tilfælde viser firkanten B,C,E,F altså glider-35 fladen i udfoldning. Ulempen ved denne udførelsesform er, at mekanismens byggelængde bliver større. Fordelen består i en meget pålidelig føring af stempelglideren.FIG. 5 shows yet another embodiment in which the slider 207 is significantly extended outside the pipes 205 and 206, so that a tube guide 208 is formed to the piston slider extension 226. This extension is provided with a set of ports 240 shown in planes A, D, E, F in FIG. 3. In both cases, the squares B, C, E, F thus show the sliding surface in unfolding. The disadvantage of this embodiment is that the build length of the mechanism becomes larger. The advantage consists of a very reliable guide of the piston slide.

Som allerede vist kan både gliderens og rørstykkernes form variere. Som antydet kan grenrøret T9 f.eks. forsynes med en ekstra ventil, hvis dette er ønskeligt. Grenrøret kan have en hvilken som helst form (f.eks. som en rørbøjning) og kan lige så godt befinde 5 sig på primærsiden som på sekundærsiden, da primærsiden kan an vendes som sekundærside, og sekundærsiden som primærside, alt afhængigt af hvilken slags anlæg mekanismen monteres.As already shown, both the shape of the slider and the pipe pieces can vary. As indicated, the manifold T9 can e.g. provided with an additional valve if desired. The manifold can be of any shape (e.g. as a bend) and may be as well located on the primary side as on the secondary side, since the primary side can be used as a secondary side, and the secondary side as a primary side, depending on the type of plant. the mechanism is mounted.

Rørstykkerne 2, 3, 5, 6 behøver ikke at ligge i samme plan, men i så fald skal portenes anbringelse i stempelglideren ændres på tilsva-10 rende måde. Når glideren har så mange porte anbragt langs omkredsen, som vist i fig. 3, må åbningerne 15,16,17,18's udstrækning i omkredsretningen begrænses tilsvarende, således at kun én port ad gangen samvirker med den tilhørende åbning.The pipe pieces 2, 3, 5, 6 do not have to be in the same plane, but in that case the position of the ports in the piston slide must be changed in a corresponding way. When the slider has so many gates disposed along the circumference, as shown in FIG. 3, the extent of the openings 15,16,17,18 in the circumferential direction must be limited accordingly, so that only one door at a time cooperates with the corresponding opening.

Reguleringsmekanismen behøver ikke at være fremstillet af rør.The regulating mechanism need not be made of pipes.

15 Den kan f.eks. være fremstillet som en støbt blok med kanaler og med en cylindrisk kanal til stempelglideren. En kombination af rør og støbt materiale, f.eks. letmetal eller plast, kan også komme på tale, navnlig til køleanlæg.It can e.g. be manufactured as a molded block with channels and with a cylindrical channel for the piston slide. A combination of pipes and molded material, e.g. light metals or plastics may also come into play, especially for refrigeration systems.

Portenes udformning kan være forskellig fra den i det foregående 20 forklarede og kan tilpasses det aktuelle behov.The design of the gates may be different from that described in the previous 20 and may be adapted to the current need.
