Abstract

The axial control valve features a measurement nozzle, which provides negative and positive pressure, used for measuring throughput and as an impulse for controlling the differential pressure or throughput. A permanent loss of pressure inside the valve due to the built-in nozzle is not increasing. On the inlet chassis the same winding features a two-part closure nut with scale and a limiting nut with protective screw. Both parts of the closing nut are connected to the detachable cogged clutch. Beneath the limiting nut there are longitudinal grooves, which are deeper than the winding and prevent the slipping of the protective screw. Both measured pressures are measured in a common measurement adapter. All connections and the pointer are located on the lower side of the chassis for easier access. Both parts of the chassis are connected by a ring-shaped nut, which prevents the penetration of the spring rim during assembly. In the flanged version, the chassis features blind winding openings, and the closure axles are located right beneath the flange diameter.

Multifunkcijski aksialni regulacijski ventilMultipurpose axial control valve

Predmet izuma je aksialni regulacijski ventil, ki lahko hkrati opravlja več funkcij. In sicer: meritev pretoka, zapiranje, omejitev odpiranja, praznjenje ter regulacijo diferenčnega tlaka in/ali pretoka. Primeren je predvsem za balansiranje dvižnih vodov v centralnih kurjavah, klimatizaciji ali ohlajevanju ter v hišnih postajah daljinskega ogrevanja ali ohlajevanja.The subject of the invention is an axial control valve that can perform several functions simultaneously. Namely: flow measurement, closing, opening restriction, discharge and differential pressure and / or flow control. It is especially suited for balancing the supply lines in central heating, air-conditioning or cooling, as well as in domestic district heating or cooling stations.

Ta izum rešuje sledeče tehnične probleme.This invention solves the following technical problems.

Problem 1. Regulator naj ima hkrati možnih več funkcij, pri tem pa naj bo čim manjši in čim krajši, vendar z veliko kapaciteto in majhno šumnostjo.Problem 1. The controller should have several functions at the same time, keeping it as small and as short as possible, but with high capacity and low noise.

Problem 2. V regulator diferenčnega tlaka ali pretoka naj bo vgrajen zanesljiv in točen merilnik pretoka, pri čemer naj bo merilno področje nastavljivo v več stopnjah.Problem 2. A reliable and accurate flowmeter should be built into the differential pressure or flow controller, with the measurement range adjustable in several stages.

Problem 3. Merilna priključka naj bosta speljana iz ohišja skupaj na istem mestu in zaprta z eno samo armaturo.Problem 3. The measuring terminals should be connected from the housing together in the same place and closed with a single armature.

Problem 4. Možno naj bo zapiranje in omejitev odpiranja, pri čemer zapiranje ne sme pokvariti omejitve odpiranja, ki mora biti točna in neodvisna od sile odpiranja.Problem 4. It should be possible to close and limit the opening, and the closing must not break the opening limit, which must be accurate and independent of the opening force.

Problem 5. Odzračevanje plus komore mora biti možno z enim samim odzračevalnim vijakom, pri horizontalni in vertikalni vgradnji regulatoija.Problem 5. Ventilation of the plus chamber must be possible with a single vent screw, with horizontal and vertical installation of regulators.

Problem 6. Iz istih sestavnih delov naj bo možno zgraditi regulator diferenčnega tlaka ali regulator pretoka, oziroma kombiniran regulator pretoka in diferenčnega tlaka.Problem 6. It should be possible to build a differential pressure controller or flow controller, or a combined flow and differential pressure controller, from the same components.

Problem 7. Skupna trajna poraba tlaka in poraba tlaka za krmiljenje regulatorja pretoka naj bo čim manjša ob čim večji točnosti regulacije.Problem 7. The total continuous pressure consumption and the pressure consumption for controlling the flow regulator should be kept to a minimum with the highest possible accuracy of regulation.

Problem 8. Vzmeti, ki so v obliki venca vgrajene v aksialnem regulatorju se pri montaži rade zvrnejo, če niso vstavljene zelo točno in brez prečnih odklonov ter prečnih obremenitev. Če se oba dela ohišja sestavljata z navojem in torej pri montaži vrtita eden proti drugemu, je pravilno lego vzmeti v vencu zelo težko doseči.Problem 8. Coil-mounted springs in the axial controller tend to rotate during mounting unless they are inserted very accurately and without transverse deflections or transverse loads. If both parts of the housing are threaded and thus rotate against each other during mounting, the correct position of the spring in the rim is very difficult to achieve.

Rešitev problemov 1-8Problem Solving 1-8

Problem 1. V že znan aksialni regulacijski ventil je vgrajena merilna šoba, zaporna matica, omejilna matica ter regulator z matico za nastavitev diferenčnega tlaka ali pretoka. Zaradi aksialne izvedbe je možna velika kapaciteta pri mali šumnosti, malih zunanjih merah in veliko funkcijah. Pri prirobnični izvedbi so namesto običajnih prirobnic v ohišju slepe izvrtine z navojem za vijake.Problem 1. The already known axial control valve includes a measuring nozzle, a stop nut, a stop nut, and a regulator with a nut to adjust the differential pressure or flow. The axial design allows for large capacities with low noise, small external dimensions and many features. In the flange version, blind holes with screw thread are provided in the housing instead of the usual flanges.

Problem 2. V regulatorje na vstopu vgrajena aerodinamično oblikovana merilna šoba, ki deluje neodvisno od položaja ventilskega krožnika. Odvzem plus in minus tlaka je izveden skozi krožni špranji, ki sta nameščeni tako, da se geometrija toka ob njiju ne spreminja. Vsaka špranja poteka po celem obodu in tako odvzema tlak iz vseh točk na obodu cevi. Rob špranj je oster in točno izdelan. Poleg tega je špranja zelo ozka in ima ustje oblikovano tako, da ne more povzročati dodatnih motenj in vrtincev. Pred vgradnjo regulatorja v cevovod se lahko glede na predvideno področje pretoka v šobo vgradi ustrezen fiksen vložek. S tem se karakteristika šobe prilagodi predvidenem pretoku.Problem 2. An aerodynamically designed measuring nozzle is built into the regulators at the inlet, which operates independently of the position of the valve plate. The extraction of plus and minus pressure is made through circular slits, which are positioned so that the flow geometry next to them does not change. Each slit runs throughout the perimeter, relieving pressure from all points on the perimeter of the pipe. The edge of the slit is sharp and precisely crafted. In addition, the slit is very narrow and has a mouth that is designed so that it can not cause additional disturbance and swirls. A suitable fixed insert may be fitted to the nozzle prior to installation of the regulator in the pipeline. This adjusts the nozzle characteristic to the intended flow.

Prednosti po izumu so sledeče. 1. Ni treba poznati položaja ventilskega krožnika, zato ni potreben mehanizem za odčitavanje položaja. Konstanta merilnika je ena sama. 2. Gladka in ozka krožna špranja izravnava vpliv turbulence toka v posameznih delih preseka cevi. 3. Oblika šobe in položaj krožnih špranj so izbrani tako, da se geometrija toka v področju špranj zelo malo spreminja. S tem se pri velikih pretokih doseže veliko večja točnost meritve kot pri znanih izvedbah, obenem pa pri zelo malih pretokih pa vsaj enaka točnost. 4. Z vložkom v šobi se lahko doseže zelo velika točnost tudi pri zelo malih pretokih.The advantages of the invention are as follows. 1. It is not necessary to know the position of the valve plate, so no mechanism is needed to read the position. The meter constant is one. 2. Smooth and narrow circular slits offset the influence of flow turbulence in individual sections of the pipe cross-section. 3. The shape of the nozzle and the position of the circular slits are chosen in such a way that the flow geometry in the slit area varies very little. This results in a much higher measurement accuracy than in known embodiments, and at the same time, at very low flows, at least the same accuracy. 4. The nozzle insert can achieve very high accuracy even at very low flow rates.

Znani ventili z vgrajenim merilnikom pretoka imajo odvzem tlaka izveden z izvrtino pred in za ventilskim sedežem. Slabosti znanih izvedb so sledeče. 1.Merilec je lahko vgrajen samo v ročni regulacijski ventil, ker pri avtomatskem regulatoiju položaj krožnika ni fiksen in zato meritev ni možna. 2. Izvrtine za odvzem tlaka so relativno majhne in imajo vstop v relativno grobi liti ali kovani steni. Zato njihova geometrija ni na vseh izdelkih točno enaka. Zaradi majhnosti so zelo podvržene lokalnim vplivom turbulence toka po preseku cevi. 3.Geometrija curka na sedežu in ob odprtinah se spreminja in vpliva na točnost meritve. 4. Meritev je odvisna od položaja ventilskega krožnika, ki mora biti točno poznan. Tolerance pri izdelavi krožnika in mehanizma za odčitavanje položaja močno vplivajo na točnost meritve. Prednost znanih izvedb pa je v tem, da lahko pri močno priprtem ventilu ob majhnem pretoku, dosežemo relativno velik padec tlaka in s tem dosežemo relativno veliko točnost meritve tudi pri zelo malih pretokih.Known valves with a built-in flowmeter have pressure extraction performed with a bore in front of and behind the valve seat. The disadvantages of the known embodiments are as follows. 1. The meter can only be built into the manual control valve, since the automatic position of the plate is not a fixed position and therefore measurement is not possible. 2. Pressure extraction bores are relatively small and have entry in relatively coarse cast or forged walls. Therefore, their geometry is not exactly the same on all products. Due to their small size, they are highly susceptible to local influences of flow turbulence after the pipe cross-section. 3.The geometry of the jet at the seat and at the openings varies and affects the accuracy of the measurement. 4. The measurement depends on the position of the valve plate, which must be accurately known. Tolerances in the design of the plate and the position reading mechanism greatly affect the accuracy of the measurement. The advantage of the known embodiments is that, with a tightly closed valve at low flow, a relatively large pressure drop can be achieved, thereby achieving relatively high measurement accuracy even at very low flow rates.

Problem 3. Odvzema plus in minus tlaka na merilni šobi sta speljana v merilno komoro in ločena z gumijastim tesnilom. Na merilno komoro je pritrjena kroglasta pipa, ki služi obenem za izpraznjevanje. Skozi pipo se vstavi kombinirano merilno cevko. Notranja cevka je za minus tlak in mora prebosti tesnilno gumo v merilni komori ter seči v področje minus tlaka. Okoli notranje cevke je zunanja cevka, ki mora segati v prostor plus tlaka, pred gumijastim tesnilom. Plus tlak se hkrati kot (dP-) impulz vodi iz merilne komore skozi impulzno izvrtino na membrano regulatoija diferenčnega tlaka, oziroma kot (V+) impulz na membrano regulatorja pretoka. Prednosti po izumu so sledeče. 1. Potreben je samo en merilni priključek na ohišju in ena zaporna armatura. 2. Zapiranje in tesnjenje navzven in proti velikemu tlaku opravi kroglasta pipa, ki se odpre samo med meritvijo. 3. Gumijasto tesnilo mora tesniti samo razliko med plus in minus tlakom, ki je relativno majhna (20 do 30 kPa). Ni potrebna absolutna tesnost. Tudi če par kapelj uide skozi tesnilo, to ni problem, ker ostanejo v notranjosti. 4. Izvrtina za plus tlak se uporablja hkrati kot impulzna izvrtina za regulacijo in izpraznjevalna izvrtina. Namesto treh izvrtin je potrebna samo ena.Problem 3. It removes the plus and minus pressures on the measuring nozzle and is fed into the measuring chamber and separated by a rubber seal. A ball valve is attached to the measuring chamber, which is also used for emptying. A combined measuring tube is inserted through the tap. The inner tube is for minus pressure and must pierce the sealing rubber in the measuring chamber and intersect into the minus pressure area. Around the inner tube is the outer tube, which must extend into the space plus pressure, in front of the rubber gasket. At the same time, plus pressure is driven as a (dP-) pulse from the measuring chamber through a pulse hole to the differential pressure regulator, or (V +) pulse to the flow regulator diaphragm. The advantages of the invention are as follows. 1. Only one measuring connection on the housing and one shut-off valve is required. 2. Closing and sealing outwards and against high pressure is performed by a ball valve which only opens during measurement. 3. The rubber seal must only seal the difference between plus and minus pressure, which is relatively small (20 to 30 kPa). No absolute tightness is required. Even if a couple drops drop through the gasket, it's no problem because they stay inside. 4. The plus pressure bore shall be used at the same time as the impulse bore for the control and the discharge bore. Instead of three holes only one is required.

Problem 4. Zapiranje in dušenje je možno z zaporno matico, ki jo sestavljata dva med seboj z razstavljivo zobato sklopko povezana obroča. Na notranji izvrtini notranjega obroča je navoj, ki vprijema v navoj na ohišju. Na zunanjem robu notranjega obroča pa je venec zob, v katerega segajo zobje zunanjega obroča. Na zunanjem obroču je skala, na ohišju pa kazalec. Ob montaži se s pomočjo zobate sklopke lahko položaj zunanjega obroča nastavi točno z ničlo proti kazalcu, ko položaj notranjega obroča ustreza pretoku nič. Po montaži se oba obroča trajno povežeta (zlepita itd), tako da se nastavitev ne more več pokvariti. Na drugo stran, proti maksimalnem odprtju je hod zaporne matice omejen z omejilno matico. Na ohišju so pod omejilno matico vzdolžni utori, v katere se sede varovalni vijak, ki je privit v omejilno matico. Zaporna in omejilna matica imata na tistem boku, kjer se stikata, po en bočni zob. Bočni zob na zaporni matici mora biti nekoliko manjši od koraka navoja zaporne matice. Tako se vrtenje zaporne matice ustavi točno in zanesljivo takrat, ko se zoba naslonita-stakneta. Znane izvedbe imajo samo eno matico, ki služi za zapiranje in omejitev hoda. Slabost znanih izvedb je vtem, da mora biti taka matica plombirana in je potrebno ob vsakem zapiranju plombo odstraniti. Prednosti po izumu so sledeče. 1. Zapiranje in omejitev odpiranja sta ločena. Zaporne matice ni treba plombirati. 2. Vrednost omejitve odpiranja je vidna od zunaj ter je zavarovana pred nenamerno spremembo. 3. Omejitev odpiranja je zelo natančna, ker je položaj NIČ ob montaži točno nastavljen s pomočjo zobate sklopke.Problem 4. Closing and damping is possible with a locking nut made up of two detachable toothed clutch connected rings. There is a thread on the inner bore of the inner ring that engages the thread on the housing. At the outer edge of the inner ring, however, there is a tooth crown into which the teeth of the outer ring extend. There is a rock on the outer ring and a pointer on the case. When mounted, the outer ring position can be adjusted exactly zero with the pointer using a gear clutch when the inner ring position corresponds to a zero flow. After mounting, the two rings are permanently connected (stuck together) so that the setting can no longer be broken. On the other hand, towards the maximum opening, the stroke of the lock nut is limited by the lock nut. There are longitudinal grooves on the chassis under which the locking nut is secured, which is screwed into the lock nut. The locking and locking nuts have one lateral tooth on the side where they are joined. The lateral tooth on the lock nut must be slightly smaller than the thread pitch of the lock nut. In this way, the rotation of the locking nut stops exactly and reliably when the teeth are leaning-glass. Known embodiments have only one nut, which serves to close and limit stroke. A disadvantage of the known embodiments is that such a nut must be sealed and the seal must be removed every time it is closed. The advantages of the invention are as follows. 1. Closing and opening restriction are separate. The lock nut does not have to be sealed. 2. The value of the opening restriction shall be visible from the outside and shall be protected against unintentional change. 3. The opening restriction is very precise, because the ZERO position at the mounting point is precisely adjusted by means of a toothed clutch.

Problem 5. Membranski disk je raven. Izvrtina za odzračevanje je speljana v najvišji del plus komore. Prednost izvedbe po izumu je vtem, da zadošča za odzračevanje v obeh položajih en sam odzračevalni vijak. Znane izvedbe sploh nimajo odzračevanja ali pa je membranski disk poševen. Slabost znanih izved je sledeča. 1. Z enim odzračevalnim vijakom se ne da odzračevati plus komore pri horizontalni in vertikalni vgradnji regulatorja. 2. Obstoja večja možnost nestabilne regulacije.Problem 5. The diaphragm disk is flat. The vent hole is inserted into the highest part of the plus chamber. An advantage of the embodiment according to the invention is that a single vent screw is sufficient for venting in both positions. Known embodiments have no venting at all or the diaphragm disc is sloping. The disadvantage of the known embodiments is as follows. 1. A single vent screw cannot vent plus chambers in horizontal and vertical installation of the controller. 2. There is a greater possibility of unstable regulation.

Problem 6. Regulator pretoka je sestavljen iz istih sestavnih delov kot regulator diferenčnega tlaka. Razlika je samo v tem, da je plus tlak meritve speljan v plus komoro pred membrano in minus tlak meritve v minus komoro za membrano. Ohišje je popolnoma enako, samo dve izvrtini sta drugače speljani. Prednost po izumu je v pocenitvi izdelave.Problem 6. The flow controller consists of the same components as the differential pressure controller. The only difference is that the plus measurement pressure is directed to the plus chamber in front of the membrane and minus the measurement pressure to the minus membrane chamber. The housing is exactly the same, only the two holes are flush. The advantage of the invention lies in the low cost of manufacture.

Problem 7. V aksialnem ventilu je premer sedeža lahko bistveno manjši od nazivnega premera ventila. Zožitev iz polnega - nominalnega premera na premer sedeža je izvedena v obliki šobe. Pad tlaka v tej šobi je relativno majhen, vendar predstavlja neizogibno del trajnega pada tlaka v ventilu. Če to že obstoječo šobo uporabimo za meritev pretoka ali krmiljenje regulatorja pretoka, se celotni trajni pad ne spremeni. Prednost izvedbe po izumu je v tem, da se zaradi merilne šobe trajni pad tlaka v ventilu ne poveča. Znane izvedbe uporabljajo za krmiljenje regulatorja pretoka razliko tlaka na nekem hidravličnem uporu, ki ima obliko ventila itd.. Slabost znanih izvedb je v tem, da je celotna poraba tlaka približno dva do trikrat večja.Problem 7. In the axial valve, the seat diameter can be significantly smaller than the nominal valve diameter. Narrowing from full - nominal diameter to seat diameter is made in the form of a nozzle. The pressure drop in this nozzle is relatively small, but it is inevitably part of the permanent pressure drop in the valve. If we use this already existing nozzle to measure flow or control the flow regulator, the total permanent drop does not change. An advantage of the invention according to the invention is that due to the measuring nozzle the permanent pressure drop in the valve is not increased. The known embodiments use a differential pressure on a hydraulic resistor in the form of a valve, etc. to control the flow regulator. The disadvantage of the known embodiments is that the total pressure consumption is about two to three times greater.

Problem 8. Vstopno in izstopno ohišje sta spojena z obročasto matico. Tako se ob sestavljanju ohišja obe dela ne vrtita, temveč samo aksialno premikata. Prednost izvedbe po izumu je sledeča. 1. Vzmeti ki so v obliki venca vgrajene v aksialnem regulatorju, se pri montaži ne morejo podreti, ker niso izpostavljene prečnim silam. 2. Ohišje je pogojno razstavljivo, tudi ko je regulator že vgrajen v cevovod. 3. Površina obročaste matice služi lahko kot napisna tablica. Pri znanih rešitvah je navoj narezan direktno na obe ohišji, ki se pri montaži privijata ena v drugo.Slabost je v tem, da se pri montaži vrtita in se vzmeti rade podrejo.Problem 8. The inlet and outlet housings are connected by a ring nut. Thus, when assembling the housing, both parts do not rotate, but only move axially. The advantage of the embodiment of the invention is as follows. 1. Coil-shaped springs mounted in an axial regulator cannot be torn apart during mounting because they are not exposed to transverse forces. 2. The housing is conditionally disassembled, even when the regulator is already installed in the pipeline. 3. The surface of the annular nut can serve as a nameplate. With known solutions, the thread is cut directly into both housings, which are screwed into each other during installation. The disadvantage is that they rotate during installation and the springs tend to tear down.
