Description
Technical field
The present invention relates to a kind of Radiator valve, this Radiator valve has fluid in a housing through-flow-control mechanism, this control mechanism has a movable element, this movable element can be handled by a push rod, an opening in the housing member of housing is passed through in this push rod guiding, and is provided with sealing system.
Background technique
The heat-carrying agent fluid of Radiator valve control by a heating unit, be generally the flow of water.Therefore, a movable valve element perhaps is positioned on the valve seat more or less fiercely near valve seat.Realize operation from the outside by a controlling mechanism for the valve element.This controlling mechanism can carry out manual operation.Common described controlling mechanism is by the hood-shaped one-tenth of thermostat.
In order to prevent that the heat-carrying agent fluid from flowing out from Radiator valve, push rod is lived housing seal by a sealing system.Because sealing system must seal up the push rod of motion, so the sealing system is subjected to certain wearing and tearing.This will cause sealing system not have sealing, and this is of course not desirable.
In order to address this problem, therefore a series of schemes have been proposed.
DD 2,010 406 discloses a kind of sealing system with a closed chamber, in the sealing chamber seal ring is being set, and the sealing ring carries out work with push rod.A guide sleeve also is installed in the sealing chamber, and this sleeve is used for carrying out radially-directed to push rod.In guide sleeve, formed another closed chamber, another seal ring is being set in the sealing chamber.Closed chamber comes locking by hold-down bolt, and this hold-down bolt is along axially carrying out work with a plane sealing element, and therefore closed chamber is sealed shut.When the sealing mechanism blow-by, must unclamp hold-down bolt, guide sleeve is unclamped from hold-down bolt, can change two seal rings then.This is a kind of comparatively bothersome scheme.The manufacturing expense of this sealing system is more expensive in addition.
EP 0 699 985 A2 disclose a kind of thermostat valve that is used for board-like heating unit, and wherein push rod seals by many O-ring seals-lip rings that are disposed in order vertically.These Sealings can not be approaching from the outside.The chamber that these Sealings are installed has only push rod to stretch out by this wall or rather by a wall sealing.In order to change described Sealing, in fact need to take apart fully valve.
DE 196 43 990 C1 disclose another kind of valve with a seal ring, and the sealing ring is arranged on the inner side surface of housing member, and push rod stretches out by this housing member.The sealing ring can not be replaced.When the sealing ring can not seal, another seal ring of packing into.Therefore, a doughnut is set on the outer side surface of housing member, in this doughnut, additional seal ring can be installed.Yet the sealing ring can be changed.But the shortcoming of using an additional seal ring to have is: changed the performance of valve, especially produced hysteresis when Xinmi City of use seal ring, because push rod must overcome the frictional force on two seal rings.When using an additional seal ring, in heating chamber, may produce other temperature changing process.
Summary of the invention
The objective of the invention is in a longer time period, to realize work reliably.
This purpose so realizes in the Radiator valve of the described type of beginning: sealing system only has the Sealing that carries out work with push rod, the sealing part can reach by a fitting opening in housing member, and this fitting opening covers by a cover.
Can realize by this scheme, can change Sealing easily when needed.The sealing part enters by fitting opening.This fitting opening covers by cover.In fact this cover has unique task: Sealing is fixed on the push rod.When removing cover, can pull down defective Sealing, a new Sealing is installed, and is covered cover again, promptly again cover is fixed on the housing member.All replacing processes can be carried out very soon, even therefore also do not worry the more fluid loss when changing.By only using a unique Sealing, the friction between push rod and the sealing system is reduced relatively.It is less that hysteresis keeps, because with opposite direction loading force the time, in fact push rod has identical kinetic characteristic.Manufacturing expense can be less, because only need less expense for the assembling of mechanical structure and valve.
Preferably, described push rod has guiding with gap by described cover.Therefore, this cover only has such task: fix Sealing.Do not need to make itself fulfil sealing function.
Preferably, cover is connected with housing member by kayser connection or clamping connection.This makes assembling be more prone to.Just cover must be pressed on the housing member, and this cover has such intensity: this intensity is enough for given function.Can be less relatively by the power that Sealing acts on the cover.
Preferably, couple together to cover and housing member rotation inhibiting and have a torsional interaction surface (Dreh-monentangriffsflaeche).In this case, can use cover that housing member is rotated.When the help by housing member realized the preliminary adjustment of Radiator valve, this was particularly advantageous.Rotation inhibiting connects and can so realize in simple mode: the interlocking geometrical shape (Ein-griffsgeometrie) between cover and housing member is not change along circumferencial direction, but changes.This for example so realizes: housing member is formed together with cover in the zone of interlocking geometrical shape angledly, perhaps has rill or similar structure.
Cover and preferably make by a kind of plastics.This has many advantages.One of them advantage is to make cover by a kind of plastics and can cause expense lower.Another advantage is that plastics are so soft or easily deformable usually, so that it is not having can be installed under the situation of bigger problem on the housing member and is being fixed on the there.
Preferably, stretch out on the outside of the opening of push rod in a doughnut, Sealing carries out pretension towards the inwall of this doughnut.Therefore push rod is surrounded by a part of housing on its a part of length, yes span.Therefore in the doughnut that forms Sealing is being installed, the sealing part compresses between the inwall of push rod and doughnut.Certainly, the sealing part also can be close on the push rod hermetically.Therefore, provide enough good sealability in a simple manner, the sealing performance can guarantee not have the heat-carrying agent fluid to let out from valve.
Preferably, doughnut has such axial length, this length greater than Sealing along the thickness that is parallel to push rod longitudinal extension direction.Therefore, the Sealing in the doughnut is with the push rod associated movement.This has the advantage of energy aspect.As long as the motion energy needed is less than overcoming the friction energy needed, Sealing just moves so.
Especially advantageously, the length of doughnut is that the twice of Sealing thickness is big at least.
Preferably, doughnut is arranged in the convex shoulder of housing member, and the wherein said outside that covers on surrounds this convex shoulder.This has improved described scheme, and for example people can be fixed on cover on the housing member.When externally remaining on cover on the convex shoulder, can cover be installed on the housing member by certain pretension.This pretension certainly makes removes described cover again by certain power from the outside.Described can be under any circumstance enough big the power that cover is fixed on the housing member, thereby can fix Sealing.
It is short that cover on the convex shoulder outer side surface cans be compared to convex shoulder most.In this case can enough instrumental purposes between cover and housing, and we can say and can take off described cover.For example advantageously, cover is positioned on the housing member for a long time and is for example clung securely under the action of high temperature of valve place existence.
Cover preferably extend in the doughnut.Cover clamps the wall of convex shoulder, that is to say the wall of clamping convex shoulder circlewise, and this has further improved retention force.
Preferably the mode of a dish with fixed-site is fixed on the push rod.This dish can be arranged rotationally with respect to push rod.But it can not remain on the push rod with losing.When not guaranteeing to be applied to clamping force on the push rod when enough big by Sealing, it can prevent that throw-out lever moves out from housing member, and this is favourable when transportation especially.Can use described dish in addition, so that under situation about breaking down, Sealing is moved out from doughnut by push rod.
Advantageously, movable element is provided with the non-return Sealing, and the sealing part carries out work with housing internally.When changing Sealing, the non-return Sealing makes valve keep sealing.Promptly in a single day the power that is applied on the movable element by push rod reduces, because push rod is pulled down from housing with Sealing, the non-return Sealing is easy to abut on the housing and there seal internally, therefore only some fluids can leak in short time durations, but valve keeps sealing for a long time.
Description of drawings
Describe the present invention below in conjunction with accompanying drawing in detail according to a preferred embodiment.Here,
Fig. 1 shows the schematic cross-sectional by a Radiator valve partly;
Fig. 2 shows an improved embodiment.
Embodiment
A Radiator valve 1 has 2, one valve seats 3 of a housing and is arranged in this housing 2, a valve element 4 and these valve seat 3 cooperatings.Valve element 4 with valve seat 3 formed be used for an a kind of fluid from 5 to outlets of an inlet, 6 heat-carrying agent fluid through-flow-control mechanism.In addition, the amount of through-flow fluid depends on the distance between valve element 4 and the valve seat 3.
One is designed to cup-shaped housing member 10 and covers on the part 9 of packing into, and its leeway is installed in housing 2 and the gap 11 between the part 9 of packing into.Housing member 10 seals by a Sealing 12 herein.Housing member 10 is fixed in the housing 2 by a sleeve 13, and its middle sleeve 13 is screwed in the housing 2, and act on one of housing member 10 around protuberance 14 on.
Valve rod 7 have one around protuberance 15, spring 8 is supported on this protuberance 15.Non-return Sealing 16 be arranged in protuberance 15 on the side of spring 8, when valve rod 7 moved in the end position on its top, spring 8 had bigger expansion, this non-return Sealing 16 is touched on an end wall 17.On this position, non-return Sealing 16 forms sealing with end wall 17, this sealing can prevent fluid from valve 1 to external leakage.
A push rod 18 is set to handle valve rod 7, these push rod 18 guiding are by an opening 19 that is arranged in end wall 17.Below opening 19, end wall 17 also has groove 20, and the upper end of valve rod 7 enters into this groove 20.
In doughnut 22, arrange a Sealing 23, encircle or circular seal ring that the sealing part carries out pretension towards the inwall 24 of convex shoulder 21 as O shape.In other words, Sealing 23 is stuck between the inwall 24 of push rod 18 and convex shoulder 21.
Doughnut 22 has relatively large length along the direction that is parallel to push rod 18 longitudinal extensions.This length is obviously bigger, promptly is that Sealing 23 is big along the twice of the thickness of equidirectional at least.Therefore, when push rod 18 moved, Sealing 23 may move together.
In order to prevent that Sealing 23 from moving out from doughnut 22, therefore be provided with a cover 25.Cover 25 is formed by plastics.This cover can be inserted on the convex shoulder 21, and since frictional force or by the attaching clamp that is not shown specifically or other fixing-or locking connection remain there.In the above-described embodiments, this cover is threaded by one and 26 is connected with convex shoulder.Cover 25 surrounds push rod 18 with certain clearance, promptly exists a gap between cover 25 and push rod 18.Therefore, cover 25 itself does not have sealing function.
Cover 25 is shorter than convex shoulder 21 on the direction that is parallel to push rod 18 longitudinal extensions, therefore can produce a gap 26 between cover 25 and housing member 10, is embedded in this gap 26 by means of an instrument, so that pull down cover 25 from convex shoulder 21.For example when needs, can adopt a screw wrench or similar instrument to embed here, and take off cover 25.
Cover 25 annular on the one hand surrounds convex shoulder 21, makes this cover on tensioning on the convex shoulder 21.But cover 25 also extend into certain-length in the doughnut 22 by a protuberance 27.Protuberance 27 will cover 25 and additionally be fixed on the convex shoulder 21.This protuberance increases the thickness of cover 25 in addition, covers 25 like this and also can bear bigger power, and can not be out of shape.At last, cover 25 has enough length, so that guiding push rod 18.
A dish 28 is fixed on the push rod 18.But coiling 28 can rotate on push rod 18.But this rim axially, promptly the longitudinal extension direction along push rod 18 can not move with respect to push rod.Usually this dish and push rod 18 stick together, and perhaps link into an integrated entity with push rod 18 similarly in another way.Therefore, dish 28 limits two end positions, that is, such end position: push rod 18 extend in the housing member 10 till arriving this end position; And another end position: push rod 18 to external movement till arriving this end position.On this end position, dish 28 is close on the Sealing 23.
Now, when Sealing 23 blow-by, to change Sealing 23 in simple relatively mode as following:
Take off cover 25 from convex shoulder 21.Therefore afterwards, can arrive push rod 18, can catch it and it is extracted with sufficient length.Coil 28 in this case as assistant tool, so that Sealing 23 is moved out from doughnut 22.Because valve rod 7 does not have to compress into immediately under the situation of power its position, upper end portion at valve rod 18, so non-return Sealing 16 is close on the end side surface 17, so valve 1 seals immediately to the outside.
Can insert push rod 18 again then, but not have power to load, and the new Sealing 23 of can packing into.Because inwall 24 has a slope 29 in upper end, institute is so that the insertion of Sealing 23 is very easy.Can move to Sealing 23 in its sealing station by plugging or clamp cover 25.Protuberance 27 is at least so big, so that Sealing 23 can be inserted in the doughnut 22 above slope 29.Therefore before non-return Sealing 16,17 was opened, when mounting cup 25, Sealing 23 sealed.
Couple together to cover 25 and convex shoulder 21 rotation inhibiting, that is, when rotating mask 25, housing member 10 is also rotated together.Therefore can use cover 25 to change the preliminary adjustment of valve.
Fig. 2 shows a kind of improved embodiment of a Radiator valve, identically in this embodiment represents with identical reference character with the function components identical.
Different with layout among Fig. 1 is that cover 25 ' no longer is fixed on the convex shoulder 21 by a kind of screw thread now.Be provided with a spring ring 30 or rather and fix cover 25 ', this spring ring is inserted in the internal annular groove 31 in the housing 2.Cover 25 ' has a corresponding outer annular groove 32, has therefore obtained a kind of fixing or kayser afterwards and connects being pressed into cover 25 '.
Between cover 25 ' and housing 2, be provided with a gap in a kind of mode that is not shown specifically at least one position on the circumference, revolving tool or another instrument is inserted in this gap with one, so that from housing 2, pull down cover 25 '.
