Therefore in other words, the present invention no longer includes socket, does not need for the clamping band that thermostat is installed on the valve fastener, in conjunction with nut etc.Now, thermostatic element be directly installed on the valve chest and therefore can think thermostatic element and control unit fixedly be combined in one i.e. connection between control gear and the valve chest.This has simplified the structure of valve.Be used for the number of parts of this valve of assembling less than the valve of prior art, because the socket of thermostat head can be omitted entirely.
Preferably, described control gear has the form of ring.This ring can be for example with respect to housing rotary with in order to change the setting value of valve.
Preferably, described control gear is formed at least two parts that connect along circumferential direction.When these parts were separated, they can be around the part location of valve chest.When they were in suitable position, they can link together, and maintaining valve housing and thermostatic element allow together and simultaneously to regulate setting value, for example, and by along moving thermostatic element towards the direction of valve seat or the direction of lifting off a seat.This setting value is desired temperature.
Preferably, described part is connected by the fastener connection.Fastener connects and only connects these parts by pressing them together.Fastener mechanism has prevented these parts separation.
In a preferred embodiment, described part is unremovably to connect.When these parts are mounted together, to only have when the connection between they or they is damaged, they just can be removed.By this way, thermostatic element cannot remove from valve.
Preferably, described thermostatic element comprises shoulder, and described shoulder is placed in the groove shapes, is formed in the wall of the described control gear that centers on described thermostatic element.The combination of shoulder and groove has provided the simple form of the axial connection between control gear and the thermostatic element, allows simultaneously in some cases control gear to rotate with respect to thermostatic element.By this way, can change the position of thermostatic element, for example pass through with respect to the housing rotary control gear.
In a preferred embodiment, except the attachment portion, described thermostatic element protrudes from described control gear fully.Thermostatic element also remains almost wholly visible and only is maintained in the control gear in the attachment portion.Most thermostatic elements are that visible this fact brings thermostatic element to resist better the advantage that inlet temperature relies on.Reason is more to be difficult to the heated constant temperature element such as fruit arranges plastic casing always, because heat can be passed to parts of plastics from parts of plastics for by the heating of valve control or the temperature of cooling medium.In addition, thermostatic element almost completely is exposed to surrounding atmosphere so that thermostatic element can be realized the fastish reaction of the temperature variation of surrounding atmosphere.
Preferably, described control gear and described housing form screw pair together, it is included in the first screw thread on the described valve chest, preferably on the outside of described valve chest, perhaps be connected on the part of described housing, and the second screw thread in described control gear, especially in the inwall of described control gear.Inwall can be identical with the wall of the groove of accommodating shoulder for thermostatic element.Yet inwall can be included in the step of dividing inwall in the different piece.When rotating control assembly, the use of screw pair is to produce the simple mode that thermostatic element moves to valve seat or lifts off a seat.
Preferably, described the first screw thread is divided at least two parts along circumferential direction.This means that screw thread turns along circumferential direction is interrupted.In principle, it is enough only using single screw thread to turn in the first screw thread.This in addition so that structure is more simple.
In a preferred embodiment, described the second screw thread forms end stop at least in described control gear leaves the moving direction of described valve seat.Therefore, control gear can not remove from valve chest by rotating it.This is rotated in end stop and is blocked.
Preferably, calibrated scale is fabricated on the outside of described valve chest, and described control gear is formed on the indicator of indicating on the described calibrated scale.Indicator can be realized by the edge of control gear.By this way, can provide the indication of the setting value that control gear regulated.
Preferably, described valve element is connected to valve rod, and described thermostatic element directly acts on the described valve rod.By this way, do not need to use the catch bar of the centre between thermostatic element and valve rod.The parts that use are fewer, and structure is simpler.

Fig. 3 is the perspective view of the valve of Fig. 1, and control gear is in complete operating position; And
Fig. 4 is the perspective view of constant temperature Controlled valve, and control gear is in a fully open position.
Embodiment
Fig. 1 schematically shows the cross section of constant temperature Controlled valve 1.Valve 1 comprises valve chest 2.Valve chest 2 has entrance 3 and outlet 4, and valve seat 5 is arranged in entrance 3 and exports between 4.Yet, can use the valve chest of other form, for example, angled housing.
Valve element 7 is at its contact valve seat 5 and be breaking at entrance 3 and export the position of the connection between 4, and removable between 5 the position of lifting off a seat, and has the passage from entrance 3 to outlet 4 in valve seat 5.Distance between valve element 7 and valve seat 5 be limit respectively the radiator that flows to connection valve 1 heating liquid volume flow parameter or flow to the parameter of volume flow of cooling liquid of the cooling unit of connection valve 1.
Valve element 7 is connected to bar 8.The axle that bar 8 is parallel to the axle 6 of valve chest 2 extends.In this example, the end 9 of bar 8 is outwardly from axle 6.
Sealed package 10 is arranged in the axle 6 of valve chest 2, has prevented from leaking to the outside at entrance 3 and the heating or the cooling liquid that export in the valve chest 2 between 4 via axle 6.In the present example, sealed package 10 comprises several O shape rings 11,12,13.Yet the form of sealed package 10 can change.
The spring 14 that opens is set up via stop device 15 and acts on the bar 8.This opens spring 14 along lifting off a seat 5 directive effect on bar 8.In other words, when not having extra masterpiece to be used on the bar 8, it is far away as far as possible that valve element 7 moves away valve seat 5.
In figure shown in Figure 1, the filler 17 of thermostatic element 16 has expanded so that thermostat 18 is compressed, and valve element 7 is pressed against valve seat 5.When the ambient air temperature step-down, the volume reducing of filler 17, and thermostat 18 can be expanded so that open spring 14 movement of valve elements 7 and lifts off a seat 5.
Adopt the control gear 20 of the form of ring to be used to connect thermostatic element 16 to valve chest 2, allow simultaneously to adjust thermostatic element 16 with respect to the position of valve chest 2.
For this purpose, thermostatic element 16 comprises shoulder 21, and it is contained in the groove 22 that is formed in the control gear 20.If necessary, shoulder and groove 22 allow control gear 20 with respect to thermostatic element 16 rotations.Yet along the direction that is parallel to bar 8, thermostatic element 16 is fixedly positioned in the control gear 20.
When control gear 20 was adjusted with respect to the position of housing 2, thermostatic element 16 was also adjusted with respect to the position of housing 2.
This adjustment can for example be undertaken by the screw pair shown in Fig. 2.
Element identical in Fig. 2 uses identical reference character.
The first screw thread 23 is arranged on the outside of valve chest 2, more accurately on the outside of axle 6.This first screw thread 23 only is included in that the single screw thread on the visible side turns (thread turn) among Fig. 2, and another the similar screw thread on the opposite side of axle 6 turns.In other words, the first screw thread 23 is divided at least two parts along circumferential direction.
Such as Fig. 1 and seen in fig. 2, thermostatic element 16 protrudes from control gear 20 fully.Only the attachment portion remains in the control gear 20, as can be seen from Fig. 1.This has the following advantages, and thermostatic element 16 is exposed in the ambient air, and it is so that thermostatic element can react to change in the air temperature around well.There is not or only has around very little resistance to heat between air and the thermostatic element 16.
On the top of thermostatic element 16, be placed with such as the label 25 with sign etc.
The part 26 of control gear 20 can be identical.Each part comprises fastener projection 27 and corresponding fastener opening 28.When control gear 20 was made by two halves or two-part 26, these parts arranged around the axle 6 of valve chest 2, this thermostatic element 16 in groove 22 accommodating shoulder 21 and on the first screw thread 23 the second screw thread 24 of placement part 26.In case part 26 has been placed on this position, then they can be pressed together so that they are connected by are connected the fastener of realizing with the fastener opening by fastener projection 27.By this way, part 26 can not be joined together with breaking away from.When the fastener detection was opened, one of them part 26 was damaged so that it no longer can be used.Screw pair can otherwise be realized.Can use the part that is connected to valve chest and carries the first screw thread 23.Also can in valve chest 2, use groove, in control gear 20, use screw thread to turn.By any way, when control gear 20 rotated with respect to valve chest 2, this screw pair allowed thermostatic element 16 to carry out translational motion.Therefore, the set point 1 of this valve can be by regulating with respect to valve chest 2 rotating control assemblies 20.
It should be noted that part 26 can otherwise connect, for example by ultra-sonic welded, screw/nut connection etc.What also it is contemplated that is to have to immerse oneself in two screws of head, from a part 26 is screwed into screw thread another part 26.In this example, can use the screw that only rotates along a direction.
Yet, the invention is not restricted to being threaded between control gear 20 and valve chest 2.
The axle 6 of valve chest 2 comprises calibrated scale 29.Seen in Fig. 3 and 4, control gear 20 forms indicator (pointer) 30, and in the present example, indicator 30 is that control gear 20 is at the edge of facing on the side of valve chest 2.
Fig. 3 shows the valve 1 with thermostatic element 16, and thermostatic element 16 has in the position of low set point at valve 1 and moves.Scale 29 hardly as seen.
In Fig. 4, thermostatic element 16 moves to the setting value of valve 1 by control gear 20 and is the position of maximum.The major part of scale 29 is visible.
