Description
Technical field
The present invention relates to a kind of thermostat valve that has a shell and a valve element, this valve element is worked with a valve seat, this valve element can be moved by a control gear, and this control gear has first thermostat element that reflux temperature is reacted and second thermostat element that another temperature is reacted.
Background technique
A kind of like this thermostat valve is for example disclosed in DE198 56 009A1.Adopt this thermostat valve, the adjusting of the heating water flow of the radiator of flowing through not only with room temperature relative, also relevant with the temperature in the return line.If the water temperature in the return line is too high, the volume flowrate of the heating water of this radiator of then flowing through is by throttling.When during with the waste heat of the waste gas of fuel combustion, when perhaps sending back to recirculation water in the heating network, for example using the volume flow quantitative limitation of such heating water by the water conservancy in the return line.
Under known situation, then ground connection of two bellows elements.Bellows element near the valve element links to each other with a remote sensor by very thin pipeline, and this remote sensor is measured the temperature of return line.Bellows element away from the valve element is used for determining room temperature.
This structure causes valve to need a huge space.This valve also stretches into the room from a radiator relatively far, and it not only influences outward appearance but also dangerous, because the user in room may tangle at the valve gap place of stretching out.
Summary of the invention
Task of the present invention provides a kind of thermostat valve of compactness.
This task solves by thermostat valve according to the present invention.This thermostat valve has a shell and a valve element, this valve element is worked with a valve seat, this valve element can be moved by a control gear, this control gear has first thermostat element and second thermostat element that another temperature is reacted that reflux temperature is reacted, wherein, first thermostat element has a structure different with second thermostat element.
Because this setting, people are no longer dependent on two thermostat elements and use the bellows element.Opposite people can make each thermostat element match with task of the present invention clearly, and it is provided with at this task.For example first thermostat element can cooperate the adjusting of reflux temperature clearly, and second thermostat element can cooperate the adjusting of another temperature especially.Under these circumstances, it at first is related to room temperature.The excursion of the room temperature excursion than reflux temperature usually is little.For this reason, second thermostat element is more greatly favourable than the degree that first thermostat element enlarges for example.The adjusting of room temperature also can be controlled the temperature of preparatory stage.People can adopt thermostat valve to regulate the temperature difference that exceeds radiator (perhaps another heat exchanger, for example floor heating).
Preferred this first thermostat element and shell are united and are carried out transmission of heat.This first thermostat element can directly obtain the temperature in the pipeline, and the shell of valve is arranged in the pipeline.This allows from pipeline and the therefore heat transmission of not losing relatively from heating water to thermostat element.This thermostat element can correspondingly therewith be shaped littlely.This further makes the valve compactness.
Preferred this first thermostat element is contained in the transmission of heat projection of shell predetermined distance of this protrusion distance second thermostat element.On the one hand, people are provided with like this, that is, make the thermostat element of winning by shell or more precisely say so and surrounded by projection, thereby guarantee the heat transmission from the shell to the thermostat element.On the other hand, people prevent that the temperature of shell is influential to the projection even second thermostat element.This second thermostat element and projection compartment of terrain are enough far away.
Especially, this projection is screwed in the shell.Be threaded and guarantee that necessary heat is transmitted from the shell to the projection.By this projection is screwed in, this projection and shell can be separated manufacturing.Therefore can enough another kind of made projections different with shell.
Preferred this projection is surrounded a loose pin, and this loose pin acts on the valve element.This projection can form symmetrically.In fact this projection is placed on the center of shell, thereby from all side heat supplieds.Basically, projection does not cause the expansion of thermostat valve, because first thermostat element is received within the projection.
Preferred this first thermostat element constitutes the wax sleeve.A wax sleeve is of compact construction.The Volume Changes relevant with temperature is generally less than the situation at the bellows element.Yet in the case, this point is not critical, because the wax sleeve is directly by the temperature of shell, more precisely by transmission of heat projection application of load.Therefore the wax sleeve can keep so for a short time, to such an extent as to keep the supply pipeline compactness.
Preferred this first thermostat element has a tappet, and this tappet reaches in second thermostat element.And this has kept the compact structure of valve.Tappet disappears in this part of second thermostat element.Adopt this structure to make the first and second thermostat element joint operations with the control valve element.We can say that first and second thermostat elements are connected in series.
Preferred this second thermostat element forms the bellows element.Bellows element can be advantageously used in the adjusting with the flow of the heating liquid of room temperature relative.
Preferred this shell is arranged in the radiator return line.Therefore this first thermostat element is directly loaded this reflux temperature.
Preferred this second thermostat element is connected with a remote sensor.This remote sensor can be configured to away from this valve.This remote sensor also only is subjected to the influence of the heat that distributes from shell among a small circle.This has improved the adjusting of room temperature.
Preferred this first thermostat element and second thermostat element have a public high pressure spring.The high pressure spring played a role in the valve down periods, the valve element abuts on the valve seat because of the rising of temperature, and the rising of temperature is owing to externalities, for example insolation, temperature in one or two thermostat elements rises, and thermostat element correspondingly expands.Expansion is allowed to by this high pressure spring, and the valve element does not carry out unallowed strong pressing to valve seat.Because two thermostat elements have only single high pressure spring, so this valve can keep compact.
Preferred this first thermostat element has a pressure spring, and this spring loads the power on the shell direction to first thermostat element.This has been guaranteed 2 points, one, thermostat element are close on the loose pin, and this sells the activity of final control valve element.Its two, the first thermostat element always keeps heat conducting with shell and is connected.
Preferably be provided with one first controlling device, it acts on the supporting member that is provided with between two thermostat elements, thereby be that first thermostat element provides a rating value, and has one second controlling device, it changes the clamping force on second thermostat element of supporting member, thereby is that second thermostat element provides a rating value.Therefore people are that two thermostat elements respectively provide a separate rating value.Influencing each other between two rating value is to eliminate by this supporting element that is arranged between two thermostat elements.
Preferred two controlling devices form handle with sleeve.By handle with sleeve is reversed towards this part of admitting handle, people can change the adjusting of rating value.
The handle with sleeve of preferred first controlling device acts on the sleeve that an adjacent support part is placed, thereby the handle with sleeve of second controlling device screws in the sleeve.This is technical simple relatively method, makes two controlling devices separately work.In addition, can also obtain a very compact structure.
Description of drawings
Present invention is described in conjunction with the accompanying drawings by means of a preferred embodiment below.Wherein:
Fig. 1 be have the valve gap of taking the thermostat valve element signal sectional view and
Fig. 2 is the state that is installed together corresponding to Fig. 1.
Embodiment
Thermostat valve 1 has a shell 2 and a valve gap 3.Shell 2 is arranged in the return line of a radiator or another heat exchanger (further not illustrating), and has 4 and outlets 5 of an inlet.At inlet 4 with between exporting 5 a valve seat 6 is set, when thermostat valve 1 was in the closed position as shown in Figure 1, a valve element 7 was by being placed on the valve seat 6.Valve element 7 is fixed on the axle 8, and when there not being other masterpiece time spent, axle 8 is open under the effect of a unlatching spring 9 of valve seat 6.
Axle 8 is by 10 controls of a loose pin, and this pin is by a sealing gland 11 guiding.Loose pin 10 and sealing gland 11 are arranged in the housing parts 12, and housing parts is substantially perpendicular to inlet 4 and the flow direction that exports between 5 extends.
Housing parts 12 has a plurality of fixed geometirc structures, for example one around cross section be the projection 13 of wedge shape, as shown in Figure 2, the fixedly finger 14 of valve gap 3 or screw thread 15 clamp these projection 13 valve gaps from the back and can fix by screw thread in another way.
A projection 16 screws in housing parts 12, and this projection 16 is surrounded loose pin 10, and it is led.Projection 16 is by a kind of good Heat Conduction Material manufacturing.The material of this projection 16 can be different with the material of shell 2, but can adopt identical materials.For example shell 2 and projection 16 can both be by the brass manufacturings.
Loose pin 10 reaches in the projection 16, exactly, reaches in the cylindrical cavity 17, and this cavity utilizes wall 18 to surround projection 16.
Valve gap 3 has one and has fixing 14 the base portion 19 that refers to.Be rotary with a nut 20 on the base portion 19, when nut screwing clamping, fixing finger 14 is pinched protrusion 13 from behind.
Base portion 19 connects with a valve gap shell 21.In valve gap shell 21, screw in one first handle with sleeve 22, the valve gap shell 21 and first handle with sleeve 22 surround an inner space 23 together.
In inner space 23, it is first thermostat element 24 of wax sleeve that a form is set.This wax sleeve is arranged in the container 26, and has a tappet 27, when wax sleeve 24 because of intensification by application of load and when correspondingly expanding, this tappet upwards ejects (as shown in Figure 1) from this container 26.Container 26 is same by good Heat Conduction Material manufacturing.
Container 26 is suspended in the retainer 25, thereby retainer 25 is subjected to load on shell 2 directions by a pressure spring 28.As shown in Figure 2, therefore guarantee that container 26 always remains on the loose pin 10.
Pressure spring 28 is supported on the supporting element 29.This supporting element 29 abuts on the sleeve 30 from the side towards shell 2 again.Sleeve 30 have one around 31, one high pressure springs of radially outer projection 32 support thereon, high pressure spring 32 is clamped between the projection 31 and first handle with sleeve 22.Sleeve 30 is resisted the power of the high pressure spring 32 in first handle with sleeve 22 and is moved.In sleeve 30, screw in a handle with sleeve 33.This handle with sleeve 33 and this inner space 34 of sleeve 30 common qualifications wherein, are provided with second thermostat element 35 of a bellows element form.This bellows element has a bellows 36, and a projection 37 of supporting element 29 reaches in this bellows.Projection 37 has a midfeather 38, and the tappet 27 that constitutes the wax sleeve of first thermostat element 24 abuts on this wall.
Second thermostat element 35 connects a remote sensor 40 by a very thin pipeline 39.But also can adopt conventional thermostat element, this element is measured the actual air temperature, and for example directly constitutes with valve.
As shown in Figure 2, under situation about constituting with valve 1, first thermostat element 24 is contained in the cavity 17 of projection 16, and is tightly surrounded by wall 18.Between wall 18 and first thermostat element 24, also just there be contacting of plane.By this plane contact, almost there is not loss from shell 2 and even heat transmission from the liquid of the valve of flowing through to first thermostat element 24.Surpass the rating value of setting by means of first handle with sleeve 22 if flow through the temperature of the hot liquid of shell 2, the wax sleeve expansion of first thermostat element 24 then, and container 26 is moved down, thereby act on the axle 8, and valve element 7 leans against on the valve seat 6 by loose pin 10.
If first handle with sleeve 22 is reversed, then by high pressure spring 32 moveable supports 29 near or away from shell.Because moving with moving of midfeather 38 of supporting element 29 links to each other, and therefore directly acts on first thermostat element 24.
Owing to, make the state of second thermostat element 35 change, and rating value also changes thus reversing of second handle with sleeve 33 on sleeve 30 opposites.Second thermostat element 35 should be controlled this rating value.This second thermostat element 35 passes through remote sensor 40 control examples such as room temperature, and acts on loose pin 10 and axle 8 by first thermostat element 24 then, opens valve or cut-off valve thereby depend on room temperature.
The operation of valve 1 is as follows:
Valve element 7 is removed the pressing of valve seat 6 by opening spring 9, and inlet 4 is freely connected to outlet 5.Heating water can shove through valve 1.Heating water is released to Heating Room by radiator with its heat.The rising of temperature is obtained by remote sensor 40, and passs on to second thermostat element 35.The internal volume increase that temperature raises and causes second thermostat element 35.Bellows 36 is compacted thus, and makes supporting element 29 move towards the direction of shell by projection 37.Therefore cause first thermostat element 24 correspondingly to shift by tappet 27.Slit between valve element 7 and the valve seat 6 is by throttling.
In addition, first thermostat element 24 obtains the temperature of shell 2, and therefore obtains reflux temperature.If reflux temperature rises, then the wax in the wax sleeve expands and repels tappet 27, makes container 26 move towards the direction of shell 2 equally.The throttling of the heating liquid of this valve that also causes flowing through.
Effect that two kinds of effects are reflux temperature and the stack of the effect of room temperature are because two thermostat elements 24,35 are connected in series.
Because first thermostat element 24 forms the wax sleeve, it has the structure of relative compact, even if also help valve gap 3 to enlarge in very little size.Adopt single high pressure spring 32 also to help to make compact structure.All reach the compact structure of having facilitated valve in second thermostat element 35 by tappet 27 and the supporting element 29 that makes first thermostat element 24 at last.
