DK 161782 BDK 161782 B
Opfindelsen angår en kombineret afspærringsventil eller taphane og kontraventil med en ventilspindel, der foretager en bevægelse i ventilens aksialretning. Det har hidtil har været almindelig praksis at anvende afspærringsventil og kontraventil som to adskilte separate 5 enheder, og årsagen hertil er, at der i vandinstallationer ikke altid har været behov for begge funktioner samtidigt. Ved visse installationer er der dog behov for begge funktioner, og der findes derfor på markedet konstruktioner, hvor begge funktioner er indbygget i samme 10 ventilhus. I princippet eksisterer der følgende to forskellige konstruktioner.The invention relates to a combined shut-off valve or tap and check valve with a valve spindle which makes a movement in the axial direction of the valve. So far, it has been common practice to use shut-off valve and non-return valve as two separate separate 5 units, and the reason for this is that in water installations, both functions have not always been required simultaneously. However, for some installations both functions are needed and therefore there are designs on the market where both functions are built into the same 10 valve housing. In principle, the following two different constructions exist.
Den mest kendte konstruktion er den traditionelle tappearmatur med stigende spindelføring, hvor ventilkeglen er frit bevægelig i spinde-15 lens akseretning, hvorved den frie kegle også kan virke som kontraventil og lukke ventilsædet for tilbagestrømning, hvis forsyningstrykket falder bort, mens tappearmaturens spindel er drejet i åben stilling.The most well-known construction is the traditional spindle luminaire with increasing spindle guide, the valve cone being freely movable in the axis of the spindle, whereby the free cone can also act as a non-return valve and close the valve seat for back flow if the supply pressure is lost while the spindle of the tappet is turned. open position.
20 Den anden kendte konstruktion er de moderne kugleafspærringsventiler, som også kan være forsynet med en kontraventil i indløbsåbningen eller i udløbsåbningen.The other known construction is the modern ball shut-off valves, which may also be provided with a non-return valve in the inlet opening or in the outlet opening.
De kendte konstruktioner har flere ulemper, hvoraf kan*anføres, at 25 tappearmaturen med spindelføring er umoderne m.h.t. såvel betjening som udseende, og endvidere kræves der et smedet eller støbt ventilhus, hvilket medfører en højere fremstillingspris. Ved kugleafspærringsventilen med indbygget kontraventil er der naturligvis ligesom 2 .The known constructions have several disadvantages, of which * it can be stated that the spindle luminaire with spindle guide is outdated with respect to. both operation and appearance, and a forged or molded valve body is also required, resulting in a higher manufacturing cost. Of course, at the ball shut-off valve with built-in non-return valve, there are like 2.

ved almindelige kugleafspærringsventiler samme risiko for, at kuglen sætter sig fast. Dette sker ofte, hvis der ikke jævnligt foretages drejebevægelse af kuglen. Det skal endvidere bemærkes, at afspærringsfunktionen og kontraventilfunktionen er to af hinanden 5' uafhængige funktioner ved denne konstruktion.in the case of ordinary ball shut-off valves the same risk of the ball getting stuck. This often happens if the ball is not rotated regularly. Furthermore, it should be noted that the shut-off function and the check valve function are two of each other 5 'independent functions in this construction.
Opfindelsen har til formål at tilvejebringe en kompakt integreret ventilkonstruktion med begge ovennævnte funktioner, og en konstruktion med sikkerhed for, at afspærringsfunktionen også virker effektivt selv 10 efter lang tids ubenyttethed.The invention has for its object to provide a compact integrated valve structure with both of the above-mentioned functions, and a structure which ensures that the shut-off function also works effectively even after prolonged disuse.
Den kombinerede afspærringsventil eller taphane og kontraventil med spindel", der foretager en bevægelse i ventilens akseretning er ifølge opfindelsen kendetegnet ved, at der i ventilhuset i strømnings-15 retningen efter.kontraventilen er placeret et åbent drejelegeme med en udragende spindel, som ved drejning kan medføre bevægelse i åbneeller lukkeretning af kontraventilens spindel afhængig af omdrejningsretning og i en bestemt drejevinkel blokerer for kontraventilens spindelbevægelse i kontraventilens lukkestilling.The combined shut-off valve or tap valve and check valve with spindle "which makes a movement in the axis of the valve according to the invention is characterized in that in the valve housing in the flow direction after the check valve there is arranged an open swivel body with a protruding spindle which can cause movement in the open or closing direction of the check valve spindle depending on the direction of rotation and at a certain turning angle blocks the check valve spindle movement in the check valve closing position.

Ovennævnte afspærringsventiler anvendes ofte på vandinstallationer med det formål at kunne afspærre installationen umiddelbart før de kendte sanitetstappearmaturer. Afspærringsventilerne står således oftest i åben stilling, og de lukkes kun i de situationer, hvor der skal ydes 25 service eller reparation på de efterfølgende sanitetsarmaturer.The above-mentioned shut-off valves are often used on water installations for the purpose of being able to shut off the installation immediately before the known sanitary tap fittings. Thus, the shut-off valves are most often in the open position and are only closed in situations where 25 servicing or repairs must be performed on the subsequent sanitary fittings.

bevægelse mellem åben og lukket stilling hver gang, der tappes vand, og der er derfor ringe risiko for, at denne vil sætte sig fast. Da afspærringsfunktionen ved konstruktionen ifølge opfindelsen tilvejebringes ved, at kontraventilen blokeres i sin lukkestilling af 5 drejelegemet i en bestemt drejevinkel, opnås der stor sikkerhed for, at afspærringsfunkionen virker effektivt, selv om denne i lang tid har været ubenyttet. Da der ved drejelegemet kun stilles krav ang. tæthed ved spindelgennemføringen i ventilhusets væg, kan drejelegemet udformes med lille friktion ved drejebevægelsen, og der opnås derved 10 en sikker og pålidelig funktion af denne drejebevægelse og følgelig også af kombiventilens afspærringsfunktion. Da kontraventil- funktionen arbejder uafhængigt af afspærringsfunktionen, når kombiventilen er i åben stilling, vil denne funktion være identisk med de hidtil kendte for kontraventiler.movement between open and closed position every time water is drained, and therefore there is little risk that it will get stuck. Since the shut-off function of the construction according to the invention is provided by blocking the non-return valve in its closing position by the rotating body at a certain turning angle, there is great certainty that the shut-off function works effectively, although it has been unused for a long time. Since the swivel body only imposes requirements on tightness in the spindle insertion in the wall of the valve body, the swivel body can be designed with little friction in the swivel movement, thereby providing a safe and reliable function of this swivel movement and, consequently, of the shut-off function of the comb valve. Since the non-return valve function operates independently of the shut-off function when the combi valve is in the open position, this function will be identical to those previously known for non-return valves.

Konstruktionen ifølge opfindelsen kan naturligvis også være sammenbygget med en anden armatur fx en termostatisk blandeventil, hvorved der i såvel den kolde som den varme tilslutning er indbygget en kombiventil ifølge opfindelsen. De indbyggede kontraventiler sikrer 20 mqd overstrømning, og afspærringsfunktionen gør det lettere at yde service på den termostatiske blandearmatur.The structure according to the invention can of course also be combined with another fixture, for example a thermostatic mixing valve, whereby a combination valve according to the invention is incorporated in both the cold and the hot connection. The built-in check valves ensure 20 mqd of overflow, and the shut-off function makes it easier to service the thermostatic mixer.
Konstruktionen ifølge opfindelsen kan også . anvendes som almindelig tappehane, hvor den indbyggede kontraventil sikrer installationen mod 25 tilbagesugning.The construction according to the invention can also. is used as a normal tapping valve, where the built-in non-return valve secures the installation against 25 return suction.

Kombiventilen består af et ventilhus 1 med gevindtilslutning i begge ender. I ventilhusets indløbskanal 2 er placeret en kontraventil 10, som støtter mod- et bryst* " 3 i ventilhusets indløbskanal 2.The combi valve consists of a valve housing 1 with threaded connection at both ends. A check valve 10 is located in the inlet duct 2 of the valve body which supports against a chest * "3 in the inlet duct 2 of the valve body.
Kontraventilen 10 låses i indløbskanalen 2 v.h.a. låsering 4, der 15 styrer i en neddrejet rille 5 i indløbskanalen 2. Låseringen 4 kan evt. være forsynet med et gitter, som udgør et grovmasket filter. Dette filter kan forhindre grove .partikler i at trænge ind i kontraventilen 10 og evt. beskadige denne. 1 2 3 4 5 6 r Kontraventilen 10 består af et udvendigt cylindrisk hus 11, der danner 2 et ventilsæde 12 i den ene ende. Det cylindriske hus tætner ved hjælp 3 af en 0-ring 13 i ventilhusets indløbskanal 2. I det cylindriske 4 kontraventilhus 11 er der placeret en fjederbelastet ventilkegle 14 5 med en O-ring 15 som tætningselement. Ventilkeglen 14 med 0-ring 15 6 kan tætne mod ventilsædet 12. Ventilkeglen 14 har en langsgående ventilspindel 16, der centrerer i kontraventilens skruefjeder 17.The check valve 10 is locked in the inlet duct 2 by a.k.a. locking ring 4, which controls 15 in a pivoted groove 5 in the inlet duct 2. The locking ring 4 can optionally be used. be provided with a grating which constitutes a coarse-mesh filter. This filter can prevent coarse particles from entering the check valve 10 and possibly damage this one. 1 2 3 4 5 6 r The check valve 10 consists of an outer cylindrical housing 11 which forms 2 a valve seat 12 at one end. The cylindrical housing seals by means of an 0-ring 13 in the inlet duct of the valve housing 2. In the cylindrical 4 non-return valve housing 11 a spring-loaded valve cone 14 5 with an O-ring 15 is provided as a sealing element. The valve cone 14 with 0-ring 15 6 can seal against the valve seat 12. The valve cone 14 has a longitudinal valve spindle 16 which centers in the non-return valve spring screw 17.

5 I strømningsretningen efter kontraventilen 10 er der i ventilhuset 1 en udboring 20 med halvkugleformet endebund 21. I denne udboring 'er der placeret et drejelegeme 22 med en udragende spindel 23. Drejelegemet kan dreje om en akse 29 og er udkærnet, så vandet kan 5 strømme forbi dette og gennem udboringen 20.5 In the flow direction after the check valve 10 there is in the valve housing 1 a bore 20 with hemispherical end bottom 21. In this bore a rotating body 22 is provided with a protruding spindle 23. The rotating body can rotate about an axis 29 and is cut out so that the water can 5 flow past this and through the bore 20.
Drejelegemet 22 er forsynet med en kurveformet flade 24, der afhængig af drejelegemets 22 drejevinkel bestemmer, hvor lang bevægelse kontraventilens spindel 16 kan foretage, og således hvor meget 10 kontraventilens kegle 14 kan åbne over ventilsædet 12. I en bestemt drejevinkel for drejelegemet 22 vil dette forhindre bevægelse af kontraventilens spindel 16, og kontraventilens ventilkegle 14 fastholdes i kontraventilens lukkestilling. Drejelegemets udragende spindel 23 er ført ud gennem ventilhusets 1 væg, og tætning ved denne 15 gennemføring tilvejebringes v.h.a. en O-ring 33. Den udragende spindel 23 er i endefladen forsynet med et profilhul eller slids 30, hvori der kan monteres et værktøj eller håndtag for drejning af drejelegemet 22 ved åbning eller lukning af afspærringsventilen. Drejelegemmet er endvidere styret i bunden af ventilhuset i form af en styretap 25 i 20 » drejelegemets omdrejningsakse 29. Denne styretap 25 kan endvidere være udformet, så den danner stop for drejelegemets drejebevægelse.The turning body 22 is provided with a curved surface 24 which, depending on the turning angle of the turning body 22, determines how long the check valve spindle 16 can make and thus how much the check valve cone 14 can open over the valve seat 12. In a particular turning angle of the turning body 22, this will prevent the movement of the check valve spindle 16 and the check valve 14 of the check valve being held in the closing position of the check valve. The protruding spindle 23 of the swivel body is extended through the wall of the valve body 1, and sealing in this passage is provided by an O-ring 33. The protruding spindle 23 is provided in the end face with a profile hole or slot 30, in which a tool or handle can be mounted for turning the rotary body 22 by opening or closing the shut-off valve. The rotary body is further controlled at the bottom of the valve housing in the form of a guide pin 25 in the axis of rotation of the rotary body 29. This control pin 25 can furthermore be designed to stop the rotational movement of the rotary body.
I drejelegemets udkærning og fastmonteret i forhold til dette kan der være placeret et filter 26, som vandet strømmer igennem, inden vandet 25 strømmer ind i udløbskanalen 6 i ventilhuset. I ventilhuset 1 i sektionen for drejelegemet 22 kan der være tilvejebragt et dæksel 27, der muliggør åbning ind til udboringen 20 og drejelegemet 22 ogIn the cutout of the swivel body and fixed relative thereto, a filter 26 may be placed through which the water flows before the water 25 flows into the outlet channel 6 in the valve housing. In the valve housing 1 in the section of the swivel body 22 a cover 27 may be provided which allows opening into the bore 20 and the swivel body 22 and

6 udtagning af filtret 26 for rensning, når afspærringsventilen er i lukket stilling. Dækslet tætner i ventilhuset v.h.a. en O-ring 31. For at lette udtagning af filtret 26 kan den udragende spindel være delt i to, hvoraf den øverste del 32, som er ført gennem dækslet 27, kan 5 fjernes sammen med dette.6 removing the filter 26 for cleaning when the shut-off valve is in the closed position. The cover seals in the valve housing v.h.a. an O-ring 31. In order to facilitate removal of the filter 26, the protruding spindle may be divided in two, the upper part 32 passing through the cover 27 can be removed along with it.
En del af drejelegemet 22 danner en kuglekalot 28, passende til den kugleformede endebund 21 i udboringen 20. Kuglekalotten 28 har samme centrum som den kugleformede endebund 21, og kuglecentrum ligger i 10 drejelegemets 22 omdrejningsakse 29. Når drejelegemet 22 drejes fra åben stilling for afspærringsventilen, d.v.s. evt. med kontraventilen i åben stilling, vil kuglekalotten 28 under den første del af drejebevægelsen, ca, 45° vinkel, delvis lukke for vandets udløb gennem ventilhusets udløbskanal 6, som har forbindelse med den 15 halvkugleformede endebund 21. Under den sidste del af drejelegemets 22 drejebevægelse, ca. fra 45 - 90° vinkel,, vil den kurveformede flade 24 evt. presse mod kontraventilens spindel 16 og bringe kontraventilen mod dennes lukkestilling. Hvis vandstrømmen er meget ringe under den sidste del af drejelegemets 22 drejebevægelse mod 20 lukkestilling, vil kontraventilens skruefjeder 17 evt. selv lukke Ψ kontraventilen. Det skal endvidere bemærkes, at kontraventilens skruefjeder 17 altid vil lukke kontraventilen, når der ingen vandstrømning er gennem kombiventilen, selv om drejelegemet står i åben stilling for afspærringsventilen. Kontraventilen foretager således en 25 åbne/lukke bevægelse hver gang, der åbnes og lukkes for en sanitetstappearmatur, som forsynes gennem den rørledning, hvor kombiventilen ifølge opfindelsen er indbygget._A portion of the pivot body 22 forms a ball sphere 28, suitable for the spherical end bottom 21 of the bore 20. The sphere 28 has the same center as the spherical end bottom 21, and the ball center lies in the pivot axis 29 of the pivot body 22. , ie Possibly. with the non-return valve in the open position, the ball ball 28 during the first part of the turning movement, about 45 ° angle, will partially close the outlet of the water through the outlet channel 6 of the valve housing, which is connected to the hemispherical end bottom 21. During the last part of the turning movement of the turning body 22 , approx. from 45 - 90 ° angle, the curved surface 24 will be press against the check valve spindle 16 and bring the check valve to its closing position. If the flow of water is very low during the last part of the rotary movement of the rotary body 22 towards the 20 closing position, the non-return valve spring 17 may be fitted. even close the Ψ check valve. It should also be noted that the non-return spring screw spring 17 will always close the non-return valve when there is no flow of water through the combination valve, even if the rotary body is in the open position of the shut-off valve. The check valve thus performs an open / close movement each time that is opened and closed for a sanitary tap fitting provided through the pipeline on which the combination valve according to the invention is incorporated.
