Description
Technical field
The present invention relates to a kind of heating body-loading type valve, have a housing and a valve seat, this valve seat is screwed in the housing by screw thread and has a coupling profile that is used to operate cover, wherein, a deformed region is set between valve seat and housing.
Background technique
This built-in valve is for example open by DE196 12 494 C1.At this, deformed region is arranged on the backstop, and when valve seat further is screwed into by the torque of touching on housing and this valve seat is increased by usefulness with this backstop, this backstop will be out of shape.
As a rule, housing has been the constituent element of heating unit, so that housing directed immutable in the space.Afterwards, the coupling profile on the valve seat determines to be assemblied in the orientation that thermostat on the valve seat covers on the angle aspect.At this, wish to be provided with a given mark, arrow for example in a precalculated position, for example allow this arrow point to vertically upward.When people only when backstop ground is screwed into valve seat in the housing, this is not always easily to realize.Being screwed into usually of just finishing before backstop touches housing is not considered, because being connected blow-by between valve seat and the housing.On the contrary, can be when its deformed region be out of shape when backstop, valve seat can be by further rotating certain angle scope so, and this is essential, so that the profile that will be coupled places on the required orientation.
The scheme of describing in DE196 12 494 C1 is proved to be favourable.
But, with some heating units of other manufacturers produce and the housing that forms thus in combination, As time goes on a problem will appear, that is, lacquer---with this lacquer coating housing lean against the distolateral of backstop---will begin to flow.This causes again, no longer can valve seat be screwed in the housing with the specified tightening force square.Under disadvantageous occasion, this can cause, and this valve seat is back-outed from housing when the operated thermostat cover, for example when counterclockwise handle with sleeve with the thermostat cover forwards the backstop place to and is rotated further then, will cause this valve seat to be back-outed from housing.
Summary of the invention
So task of the present invention is, avoids valve seat to deviate from from housing.
Task of the present invention will start in the heating body-loading type valve of described type at this paper and solve in the following manner, that is, deformed region is set at enclosure interior.
This configuration has advantage, that is, deformed region is set in the zone, and this zone is no time dependent cover coat usually.Do not paint usually in the inside of housing.Correspondingly, owing to the mobile problem that causes of lacquer is eliminated practically.Usually, in when japanning, opening in the housing and the opening that is screwed into valve seat later on pass through plug closes.On the other hand, can make in this mode that the connecting pipe of shell that surrounds valve seat is distolateral is painted as before.Avoid those zones that are not painted to get rusty thus.At last, can realize, valve seat after being screwed into, still as seen and afterwards do not kept lessly by what the thermostat cover hid.For vivid reason, selected this notion " deformed region ".It is a contact area basically, wherein, distortion to a certain degree occurs, and this distortion is essential, so that cause sealing.
Preferred housing has a conical surface in a hole that receives valve seat, valve seat with deformed region by touching on this conical surface.Thereby deformed region is set in the zone of the conical surface.This conical surface makes valve seat become easily to the importing in the hole again because this valve seat in importing to the hole time by this conical surface guiding.This conical surface be positioned at the hole the outer end near.The sub-fraction that when being implemented in the generation distortion thus only is the valve seat axial length mechanically is subjected to load.This makes the design of valve seat become easily and the low cost of manufacture of valve seat again.
In one first configuration, stipulate that deformed region is made of rib, rib and described conical surface acting in conjunction.Obtain two anamorphic effects at this, promptly on the one hand by rib clamp-oning and the distortion by rib on the other hand to the conical surface.These two effects which account for leading, can be on the one hand from the material hardness that is used for housing and obtain from the material hardness that is used for valve seat on the other hand.But final, as long as distortion occurs, this distortion allow valve seat above one first backstop be screwed into, so which of this two parts can be out of shape be inessential.
In one second configuration, stipulate, valve seat have one around, flange that a relative body is provided with radial spacing, flange when being screwed into by the conical surface radially to internal strain.Then, should around flange be deformed in this spacing.At this, be used to be screwed into required torque and increase gradually.
A seal ring preferably is set between flange and body.When flange was bent on the body, the sealing circle was extruded from described spacing and under pressure in the sealing area between valve seat and housing.
At this, particularly advantageously be, body its side towards flange have one around the inclined-plane.This inclined-plane make seal arrangement easily the chamber between flange and body the direction to housing extrude.
Favourable also has, and valve seat has a projection that radially protrudes in flange.In this case, this projection in fact indeformable or only distortion indistinctively when valve seat is screwed into body.This mainly has visual reason.Valve seat can slightly deeper be screwed in the housing basically then.
Consider that in one the 3rd possibility valve seat has a relative conical surface, this relative conical surface has the cone angle that is different from the described conical surface, this relative conical surface when being screwed in the zone at the relative conical surface under the distortion of valve seat by touching on the described conical surface.Then, the distortion of valve seat axially begins on the inner end of the relative conical surface.Because along with the increase that is screwed into the degree of depth, the increasing zone of the conical surface must be out of shape relatively, improves a certain amount of so be used to be screwed into required torque.
Also can consider, valve seat have one radially outstanding, around radial flange, radial flange axially is being out of shape when contacting on the conical surface.This radial flange constitutes a kind ofly can axially have the form of springs of certain preload towards housing.When valve seat up to backstop even when being screwed in the housing with surmounting backstop slightly, it is directed that this radial flange can be parallel to the distolateral ground of valve seat so.
At this, preferably, the thickness of the radially outer of this radial flange is less than the thickness of inner radial.This makes that being screwed into becomes and causes a progressive indicatrix again easily and for being screwed into moment.
Preferred screw thread have by plastics, the coating of PTFE especially.This for example can spray the coating that forms and is utilized, so as between valve seat and housing in sealing of region generating of screw thread.
Alternatively or additionally, also can consider, on the part of the axial length of screw thread, a plastic hoop of especially being done by PTFE is set.This plastic hoop can be used as solid parts and constitutes.But it also can relate to a plastic tape one or more layers, and this plastic tape can be reeled circlewise.At this, also sealing in the zone at Sealing between housing and the valve seat.
At last, possible still is that a circular seal ring is set in screw thread.A circular seal ring also can be called as " O-ring seals ".For it is set, in valve seat---exactly, on the axial length of screw thread---conform with the destination circular groove is set.When being screwed into valve seat in the housing, this circular seal ring is compressed in this circular groove.
Screw thread preferably is configured to taper.This taper configurations can realize in the following manner, that is, that the body of valve seat is configured to taper and make screw thread with identical height of thread there.Can consider that also some between the single screw thread channel " paddy " flatten.Then, along with the increase of the degree of depth, being screwed into required moment also increases.This configuration has two advantages.On the one hand, the unavailable hand of valve seat is back-outed from housing.On the other hand, with little seal approach, for example spray the sealing that is connected just can make between valve element and the housing carrying out PTFE on the screw thread.
Can consider that also screw thread has zigzag cross section.In other words, single " tooth " of screw thread has such cross section, that is, one of them flank of tooth extends perpendicular to the axis of screw thread, and the axis of another flank of tooth phase double thread extends with certain angle.When valve seat was screwed in the housing, it can be out of shape in the zone of screw thread, because " tooth " of screw thread only also constitutes with the strength of materials of half.In fact this deformed region is in the screw thread.
Favourable also has, and a spring sheet fixing device is set in screw thread.Also can use a spring sheet fixing device, so that guarantee that valve seat can not back-outed from housing.At this, this spring sheet fixing device can have different structures.Can use a spring sheet, its be pressed in the screw thread and also we can say the screw thread that is set at valve seat and the screw thread of housing between.This spring sheet needn't extend on the whole circumference of valve seat.It extends just enough basically on part axial length and circumference.This spring sheet fixing device also can be made of an elastic ring, elastic ring be set at one around groove in, wherein, should around groove be positioned at the axial inner of screw thread.When being screwed into, this elastic ring is by radial compression and be extended in " paddy " in the outside thread, but only on the part of circumference.Also can avoid valve seat to be back-outed thus from housing.
Description of drawings
Below according to preferred embodiment and accompanying drawings the present invention.Shown in the drawings:
Fig. 1: the schematic cross sectional views of heating body-loading type valve,
Fig. 2: the partial view of amplification,
Fig. 3-14: the different forms of implementation of housing and valve seat combination.
Embodiment
Fig. 1 illustrates 1, one valve seat 3 of heating body-loading type valve with a housing 2 and is screwed in this housing.This housing 2 has the adapter 4 of a band internal thread 5, is used to receive described valve seat.This valve seat has outside thread 6, the latter and 5 engagements of described internal thread.
This housing 2 is painted on its outside, preferably is coated with the color with heating unit.This lacquer also extend in take over 4 distolateral 10 on, but do not extend to the inside of housing 2.
Fig. 2 illustrates the details II among Fig. 1.As can be seen, take over 4 and in the zone of its opening, have a conical surface 11.This conical surface 11 makes valve seat 3 easily to import to and takes in 4.But this conical surface 11 also has other tasks under current situation.Valve seat 3 have one around rib 12, rib when valve seat 3 is screwed into certain depth by touching on the conical surface 11.If should realize by touching, the profile 7 that also not necessarily guarantees to be coupled has the orientation of correct angle aspect, that is, these ribs 8 are in such position, and a mark, arrow for example are shown on the thermostat cover in this position subsequently vertically upward.In order to reach this position, angle, valve seat 3 can exceed rib 12 being rotated further by contacting to earth on the conical surface 11.At this, decide on the material hardness of housing 2 and the material hardness of valve seat 3, or rib 12 is imbedded in the conical surface 11, or with the gradient of rib 12 leveling and the adaptive conical surface 11.As a rule, also can consider the combination of described two kinds of phenomenons.Then, valve seat 3 can be rotated further, up to reaching coupling profile 7 orientation aspect the required angle in the space.
This has additional advantage, that is, as seen valve seat 3 only keeps with little flange 13 ground.Even this flange 13 can not be capped during suit thermostat cover afterwards yet.This flange 13 has a peripheral wall 14, and its aspect ratio is less, for example at the order of magnitude of 1mm.
By rib 12 and housing 2 unvarnished, be that the conical surface 11 cooperates, lacquer---because on the conical surface 11 not lacquer---can not exert an influence to afterwards the relation of valve seat 3 in housing 2.Especially avoided this risk, that is, lacquer begins to flow and change resistance under certain load, and valve seat 3 is screwed in the housing 2 with this resistance.The moment of screwing that valve seat 3 is remained in the housing 2 remains in the whole circumference and obtains.
There are various schemes in---this deformed region is made of in the inside of housing 2 rib 12 and the conical surface 11 in according to the configuration of Fig. 1 and 2---for deformed region, and these schemes are by Fig. 3-14 explanation.Also show different schemes in these accompanying drawings, that is, how being connected between seal valve seat 3 and the housing 2 avoids liquid to flow out.
Fig. 3 once more illustrate on the principle according to Fig. 1 and 2, have by touching the configuration of the rib 12 on the conical surface 11.Also show O-ring seals 15, the latter is being screwed into valve seat 3 distortion when taking in 4.This O-ring seals 15 be set on the valve seat 3 one around groove 16 in, exactly, in the zone of the axial outer end portion of outside thread 6.
Fig. 4 illustrates a kind of form of implementation, and wherein, housing 2 also has a conical surface 11.Valve seat 3 has a relative conical surface 17.The conical surface 11 and the relative conical surface 17 have different cone angles.With respect to being screwed into direction, it is more flat that the relative conical surface 17 is configured ground.If now valve seat 3 is screwed in the housing 2, then the axial inner ends portion of the at first relative conical surface 17 is by touching on the conical surface 11.Then, when further being screwed into, valve seat 3 is out of shape in the zone of the relative conical surface 17, wherein, relatively the conical surface 17 gradually to the conical surface 11 by touching.At this, this contact needn't fully be carried out.If after the further little spoke of valve seat 3 rotates, reached the correct location of coupling profile 7 in the space, between the conical surface and the relative conical surface 17, can keep a gap 18 fully so.
Outside thread 6 is provided with the coating by plastics, especially PTFE.This coating can be sprayed and be formed.This coating has guaranteed the sealing that is connected between housing 2 and the valve seat 3.
Fig. 5 illustrates the flexible program according to the configuration of Fig. 4.At this, also be provided with a conical surface 11 on the housing 2 and on valve seat 3, be provided with a relative conical surface 17, when valve seat 3 was screwed in the housing 2 fully, their level lands contacted with each other.This is shown in upper half part of Fig. 2.
Sealing between valve seat 3 and the housing 2 is undertaken by the seal ring 19 by plastics, especially PTFE, and seal ring is set in the groove 20.Groove 20 reaches thus, and seal ring 19 is within the axial length of outside thread 6.
Fig. 6 illustrates the flexible program according to the configuration of Fig. 5.The deformed region that constitutes by the conical surface 11 and the relative conical surface 17 is configured to the deformed region among Fig. 4 and 5 the same.Sealing is to place the O-ring seals 15 of a groove 20 to carry out by one, and this groove 20 is in the axial outer end portion of outside thread 6.
In configuration according to Fig. 4-6, by the deformed region that in the zone of the conical surface 11 and the relative conical surface 17, constitutes, from the radial inner end of the relative conical surface 17 by touching the moment that is screwed into that moment on the conical surface 11 obtains increasing.Afterwards, being screwed into moment raises.Equally, be used for also raising from the housing 2 valve seat 3 required moments of back-outing.Realize two effects thus.On the one hand, coupling profile 7 can forward on the required orientation in the space.On the other hand, valve seat 3 will be fixed in the housing 2 reliably.
Fig. 7 illustrates a different slightly scheme, and this scheme also can be in conjunction with the different cone angle on the conical surface 11 and the relative conical surface 17.
In the embodiment according to Fig. 7, outside thread 6 is by taper ground structure, and that internal thread 5 still is essentially is cylindrical.
As by the first half of Fig. 7 is compared as can be known with the Lower Half of Fig. 7, it causes, and the valve seat in the axial outer end portion of outside thread 6 is pressed by pier radially.Being used for pier presses outside thread 6 required power to increase along with being screwed into the degree of depth.
For the sealing of valve seat 3 relative housings 2, can use means in conjunction with Fig. 4-6 explanation, that is, outside thread 6 is carried out coating, a plastic hoop or an O-ring seals with plastics especially PTFE.
Fig. 8 illustrates another configuration, wherein, valve seat 3 have one around radial flange 21, the thickness specific diameter of radial flange radially outer is little to the thickness of inside.Valve seat 3 is being screwed under the situation of housing 2 certain depths, this radial flange 21 is by touching on the conical surface 11.O-ring seals 15 is in the wedge crack between radial flange 21 and the outside thread 6.
As long as reach the degree of depth that is screwed into shown in Fig. 8, then have only with higher to be screwed into moment and valve seat 3 further could to be screwed in the housing 2.So, this increases is screwed into torque and will causes axially outwards distortion of radial flange 21.Also we can say radial flange 21 axially outside warpages.At this, this O-ring seals 15 will be compressed and sealing between housing 2 and valve seat 3.
Fig. 9 illustrates a kind of configuration, wherein, valve seat have one around flange 22, the body 24 of the relative valve seat 3 of flange is provided with a spacing 23.Outside thread 6 is on the radial outside of body 24.O-ring seals 15 is set in the spacing 23.
Now, the available common moment that is screwed into is screwed into valve seat 3 in the housing 2, up to flange 22 by touching on the conical surface 11.Afterwards, must improve and be screwed into moment.
The moment that is screwed into that this increases causes, and flange 22 is radially inwardly pressed on the conical surface 11 and correspondingly radially to internal strain.This situation illustrates in the bottom of Fig. 9.
Basically constitute one around the spacing 23 of groove have a bottom that is configured to inclined-plane 25.Now, O-ring seals 15 is radially inwardly to push inwardly and mainly radially on this inclined-plane 25, so that it reaches in the position shown in the bottom of Fig. 9.
Figure 10 illustrates a kind of basically corresponding to the configuration of Fig. 9.But here one around projection 26 radially stretch out above flange 22.Compare with the configuration according to Fig. 9, this flange 22 radially more upcountry is provided with.This will cause, and in the state of being screwed into, under any circumstance distolateral 27 of projection 26 all as seen, and this has improved visual appearance.
In the configuration according to Fig. 9 and 10, deformed region forms by the acting in conjunction of the conical surface 11 with flange 22.
Figure 11 illustrates another embodiment, and wherein, outside thread has special shape.In sectional view, outside thread 6 has tooth, and these teeth constitute the sawtooth profile.In order to explain, the flank profil 28 of an amplification is shown in the inside of valve seat 3.This flank profil 28 has the flank of tooth 29, and the flank of tooth axially outwards points to and tilts in a conventional manner.The flank of tooth 30 on opposite, be that in fact the flank of tooth 30 of axial inner extends perpendicular to being screwed into axis ground.When valve seat 3 was screwed in the housing 2, tooth 31 so---shown in Figure 11 bottom---can be out of shape in the axial direction.Therefore, deformed region constitutes by the acting in conjunction of internal thread 5 with outside thread 6.
Sealing is undertaken by an O-ring seals 15, and this O-ring seals is set in the axial outer end portion of outside thread 6.
A similar configuration shown in Figure 12, wherein, flank profil 28 also is configured to zigzag fashion.But the axial outer flank of tooth 29 of tooth 31 points to perpendicular to being screwed into axis ground here, and axially inner toothed surface 30 tilts in a conventional manner.In this configuration, deformed region also is that the acting in conjunction by the outside thread 6 on the internal thread on the housing 5 and the valve seat 3 realizes.
Figure 13 illustrates an additional fixation, is used to avoid valve seat 3 to back-out from housing 2.At this, an elastic plate 32 is set between internal thread 5 and outside thread 6.This elastic plate 32 cover outside threads 6 axial length a part and also cover the part of the circumference of outside thread 6.
Figure 14 illustrates an elastic ring 33 and replaces elastic plates 32, and elastic ring is placed in the groove 34 in the outside thread 6.This elastic ring 33 allows valve seat 3 to be screwed in the housing 2.In the process of being screwed into, elastic ring 33 is compressed.As long as valve seat 3 reaches a position of rest, elastic ring 33 can expand slightly and be engaged to thus again in the backlash space between these teeth of internal thread 5 so.
In all aforesaid forms of implementation, not only elastic plate 32 but also elastic ring 33 all can be used as additional, anti-fixing device of back-outing.
