Description
ssoovzs-7 2 Vid hittills kända ventilsystem uppstår ofta radialkrafter på ventilspindeln med slitage på spindeltätning och -styrning som följd. Vid ventilsystemet enligt föreliggande uppfinning erhålles en rent axiell rörelse på ventilspindeln, vilket medför längre livslängd på såväl cylinder som ventilsäten och därmed en effektivare öppning och stängning av ventilen. ssoovzs-7 2 In hitherto known valve systems, radial forces often occur on the valve stem, with wear on the stem seal and control as a result. With the valve system according to the present invention, a purely axial movement is obtained on the valve stem, which results in a longer service life of both cylinder and valve seats and thus a more efficient opening and closing of the valve.
Uppfinningen kommer att närmare beskrivas i anslutning till bifogade ritning, där fig 1 visar ett längdsnitt av en ventil och dess infästning i en spridarramp. Fig 2 visar ett tvärsnitt genom ventilen utefter linjen A-A i fig 1.The invention will be described in more detail in connection with the accompanying drawing, in which Fig. 1 shows a longitudinal section of a valve and its attachment to a spreading ramp. Fig. 2 shows a cross section through the valve along the line A-A in Fig. 1.
I fig 1 visas en ramp 1 i vilken en ventil 2 är monterad. Ventilen regleras med hjälp av tryckmedium och är uppbyggd som en konventionell tryckluftcylinder med tillhörande kolv och kolvstång. Cylinderdelen 3 är ingängad i rampväggen 1 och kolvstången som i föreliggande fall benämns ventilspindel 4 är förlägnd och sträck- er sig ut ur cylindern 3 och in i rampen 1. ' ' Ventilspindeln 4 är i sin inuti cylinderdelen 3 befintliga ände utrustad med en kolv 5 och i sin andra ände med en ventilkägla 6 och sträcker sig från cylinder- delen 3 och diametralt in i rampen 1 till dess motsatta vägg, i vilken ett mot ventilkäglan 6 svarande ventilsäte 7 är inskruvat. Ventilen 2 öppnar och stänger genom att ventilkäglan 6 bringas från och till anliggning mot ventilsätet 7.Fig. 1 shows a ramp 1 in which a valve 2 is mounted. The valve is regulated by means of pressure medium and is constructed as a conventional compressed air cylinder with associated piston and piston rod. The cylinder part 3 is concealed in the ramp wall 1 and the piston rod, which in the present case is called valve spindle 4, is located and extends out of the cylinder 3 and into the ramp 1. The valve spindle 4 is equipped at its end inside the cylinder part 3 with a piston 5 and at its other end with a valve cone 6 and extends from the cylinder part 3 and diametrically into the ramp 1 to its opposite wall, in which a valve seat 7 corresponding to the valve cone 6 is screwed. The valve 2 opens and closes by bringing the valve cone 6 from and to abutment against the valve seat 7.
Ventilkolven 5 är rörlig inuti cylinderrummet 8, vilket kommunicerar med en öpp- ning 9 i cylinderväggen genom vilken tryckmedium kan tillföras cylinderrummet 8 och bringa kolven 5 och därmed ventilspindelns 4 ventilkägla 6 från anliggning mot ventilsätet 7. Ventilen återföres till anliggning mot ventilsätet 7 med hjälp av en fjäder 10, vilken är så förspänd att den håller ventilen stängd vid tryck- mediumbortfall. Fjädern 10 har även till uppgift att förspänna den tätning 11 som är avsedd att förhindra bindemedel att under ventilrörelsen tränga ut från rampen 1 och in i cylindern 2. Tätningen 11 består av V-ringar som genom kilverkan trycks mot ventilspindeln 4 och cylinderhuset 3.The valve piston 5 is movable inside the cylinder space 8, which communicates with an opening 9 in the cylinder wall through which pressure medium can be supplied to the cylinder space 8 and bring the piston 5 and thus the valve cone 4 of the valve stem 4 from abutment against the valve seat 7. The valve is returned to abutment against the valve seat 7 of a spring 10, which is so biased that it keeps the valve closed in case of pressure medium failure. The spring 10 also has the task of prestressing the seal 11 which is intended to prevent adhesive from penetrating from the ramp 1 and into the cylinder 2 during the valve movement. The seal 11 consists of V-rings which are pressed against the valve stem 4 and the cylinder housing 3 by wedge action.
Fjädern 10 är därvid så dimensionerad att den håller tätningen förspänd, även efter en viss förslitning av tätningen 11.The spring 10 is then dimensioned so that it keeps the seal biased, even after a certain wear of the seal 11.
Cylinderrummet 8 är upptill avgränsat av ett hylsformat på cylindern pâskruvat lock 12. Cylinderhusets yttervägg har gjorts sexkantigt, för att bättre ge fäste för exempelvis en skruvnyckel då huset skruvas fast i rampväggen. Hylslocket 12 är emellertid cylindriskt och så dimensionerat att spalter 13 bildas mellan cy- 3 8500723-7 linderhuset och hylslocket 12. Spalterna tjänstgör som avluftningskanaler för den ovanför kolven 5 befintliga luften när tryckmedium pressas in genom öppningen 9 och trycker kolven 5 uppåt och därmed öppnar ventilen så att bindemedel kan strömma -ut från rampen 1 genom ventilöppningen 14. För att förhindra att tryckmedium träng- er ned i rampen 1, är cylinderrummet 8 nedtill tätat genom en tätningsring 15, vil- ken tätar mot ventilspindeln 4 och cylinderhuset 3. Om läckage av tryckmedium eller bindemedel uppkommer, exempelvis till följd av förslitning av tätningen 15 respektive tätningen 11 så avleds detta genom en dräneringskanal 16 upptagen i cylinderhusets vägg.The cylinder space 8 is delimited at the top by a sleeve-shaped lid 12 screwed onto the cylinder. The outer wall of the cylinder housing has been made hexagonal, in order to better provide a mount for, for example, a wrench when the housing is screwed into the ramp wall. However, the sleeve cover 12 is cylindrical and so dimensioned that gaps 13 are formed between the cylinder housing and the sleeve cover 12. The gaps serve as vent channels for the air present above the piston 5 when pressure medium is forced in through the opening 9 and pushes the piston 5 upwards and thus opens the valve so that adhesive can flow out of the ramp 1 through the valve opening 14. To prevent pressure medium from penetrating into the ramp 1, the cylinder space 8 is sealed at the bottom by a sealing ring 15, which seals against the valve stem 4 and the cylinder housing 3. If leakage of pressure medium or adhesive occurs, for example as a result of wear of the seal 15 and the seal 11, respectively, this is diverted through a drainage channel 16 accommodated in the wall of the cylinder housing.
Genom att cylinderhuset 3 och ventilsätet 7 är monterade så långt från varandra, uppstår krav på monteringens exakthet för att en effektiv ventiltätning skall er- hållas. För att undanröja detta problem är ventilkäglan 6 skålformad och påträdd ventilspindelns 4 nedre ände med ett radiellt spel. Genom en sprint 17 som går genom ett hål 18 i spindelns 4 nedre ände och sträcker sig på båda sidor om spin- deln in genom hål i kägelväggen, hålls käglan 6 kvar på ventilspindeln 4. Hålets 18 diameter är större än sprintens 17 diameter, vilket ger käglan 6 möjlighet att röra sig axiellt i förhållande till ventilspindeln 4.Because the cylinder housing 3 and the valve seat 7 are mounted so far apart, requirements arise for the accuracy of the assembly in order to obtain an effective valve seal. To eliminate this problem, the valve cone 6 is cup-shaped and the lower end of the valve stem 4 is threaded with a radial play. Through a pin 17 which passes through a hole 18 in the lower end of the spindle 4 and extends on both sides of the spindle in through holes in the cone wall, the cone 6 is kept on the valve spindle 4. The diameter of the hole 18 is larger than the diameter of the pin 17, which allows the cone 6 to move axially relative to the valve stem 4.
Infästningen av käglan 6 medger således en såväl axiell som radiell rörelse rela- tivt ventilspindeln 4, vilket medför att kravet på exakthet vid inmonteringen av cylinderhus och ventilsäte kan avsevärt reduceras utan att tätningskravet behöver eftersättas.The attachment of the cone 6 thus allows both axial and radial movement relative to the valve stem 4, which means that the requirement for accuracy in the installation of the cylinder housing and valve seat can be considerably reduced without the sealing requirement having to be waived.
För att ytterligare säkerställa tätningskravet är en tätningsring 19 placerad i ventilsätet 7. Ringen är av mjukt material och har dessutom den egenskapen att bindemedlet i rampen 1 inte fastnar på densamma. Genom att ringen 19 är av mjukt material, säkerställes tätningen -mellan denna och ventilkäglan 6, även om en fast partikel skulle befinna sig mellan kägla och sätesring under ventilstängningsmo- mentet. Den fasta partikeln trycks då in i ringen utan att någon spalt uppstår.To further ensure the sealing requirement, a sealing ring 19 is placed in the valve seat 7. The ring is made of soft material and also has the property that the adhesive in the ramp 1 does not stick to it. Because the ring 19 is of soft material, the seal between it and the valve cone 6 is ensured, even if a solid particle would be located between the cone and the seat ring during the valve closing moment. The solid particle is then pushed into the ring without any gap.
Vid den efterföljande öppningen av ventilen spolas partikeln med bindemedlet ut genom öppningen 14.At the subsequent opening of the valve, the particle with the binder is flushed out through the opening 14.
Hålet i rampväggen 1 i vilket cylinderdelen 3 är inskruvad är lämpligen förstärkt med en invändigt gängad bussning 20. Cylinderdelen 3 skruvas in i bussningen 20 till dess en stoppmutter eller stoppring 21 på cylinderhuset kommer till anligg~ ning mot en på bussningen 20 utformad fläns 22. För att förhindra bindemedel att tränga ut genom bussningens gänga är en tätningsring 23 anordnad mellan cylinder- hus och bussning.The hole in the ramp wall 1 in which the cylinder part 3 is screwed in is suitably reinforced with an internally threaded bushing 20. The cylinder part 3 is screwed into the bushing 20 until a stop nut or stop ring 21 on the cylinder housing comes into contact with a flange 22 formed on the bushing 20. To prevent adhesive from penetrating through the thread of the bushing, a sealing ring 23 is arranged between the cylinder housing and the bushing.
