Description

Radiator valve, particularly built-in valve

Technical field

The present invention relates to a kind of radiator valve, particularly built-in valve, this valve comprises inlet passage, discharge route, the valve seat between inlet passage and discharge route, valve element and the preset that cooperates with valve seat.

Background technique

It is in order to control the heat transport fluid by heater that people use this radiator valve, for example the flow of hot water.According to the distance that the valve element is promoted by valve seat, the heat transport fluid of greater or lesser amount flows through heater.If the valve element is close on the valve seat, flowing of heat transport fluid is under an embargo usually.

This radiator valve often also has preset.This preset comprises throttle valve, and this throttle valve is determined the peak rate of flow by the heat transport fluid of radiator valve.Even when valve is opened fully, also can pre-determine additional restriction by preset.

Summary of the invention

Task of the present invention is to expend realization preconditioning with very little.

This task is that the mode that constitutes the part of preset by the valve element in the radiator valve of the described type of beginning is solved.

People use the valve element, not only in order to influence the open cross-section that forms between valve element and valve seat.People use the valve element, also are in order to produce the preconditioning effect.Because the valve element after all must be from peripheral operation, therefore the valve element is carried out additional operations and only can cause seldom surcharge in order to produce the preconditioning effect.

Here preferably, preset can be regulated by the rotation of valve element.Normally, the working control function of valve element is to move point-blank by the valve element, promptly towards valve seat or lift off a seat and produce.If additionally allow now the motion possibility of valve element, promptly rotate, not pre-conditioning unit is regulated by the influence ground of the open cross-section that between valve element and valve seat, forms.

Preferably, the valve element has window, and the throttle element of preset has opening, and this window and this opening can relativity shifts.Depend on the degree that window and opening cover mutually, heat-carrying stream is by the stronger or more weak ground throttling of valve quilt.But this simply by throttle element and the relative movement of valve element be provided with and produce.

Preferably, inlet passage has the passway, and this passway forms valve seat and surrounds discharge route.This design proposal for example can be used to enlarge the ability of valve.The heat transport fluid that flows through inlet passage can be that many times of ground flow out through this passway towards both sides.

Preferably, throttle element stretches in the valve element.Therefore, can realize simultaneously that the valve element is directed by throttle element.

Preferably, throttle element is arranged still with respect to valve seat.This structure of radiator valve is therefore fairly simple.In fact, only need throttle element to be fixed on the valve seat, perhaps throttle element is integrally formed with the valve member that supports valve seat at the very start.

A kind of replacement scheme is that throttle element can be can be with respect to valve seat and/or move with respect to the valve element in the axial direction.In this case, throttle element is with respect to valve seat, perhaps with respect to the valve element, perhaps with respect to both skews.The adjusting possibility that this obtains increasing.

Preferably, throttle element with respect to the antitorque commentaries on classics of valve seat be held.Yet, remain possible with respect to the axial motion of valve seat.Therefore, in simple mode, the rotation by the valve element can make throttle element be offset in the axial direction.For this reason, only need being threaded between throttle element and the valve element.

Preferably, throttle element is designed to have the tube (Buchse) that stretches into the end face in the discharge route, and the periphery edge of this end face extends to outside the plane vertical with the moving direction of throttle element.Depend on the distance that throttle element is offset, so this periphery edge fully or the passway that just partly is discharged from passage hide, thereby also therefore can carry out preconditioning to a certain degree, promptly be not or just by window and opening.

Here preferably, this periphery edge tilts with respect to this plane.That is to say that this end face of throttle element is designed to tilt.

In a kind of alternative design proposal, can carry out following design: this periphery edge is with respect to this plane waviness.Depend on throttle element from the distance that discharge route outwards moves, produced a plurality of holes so, the size in these holes depends on the position of throttle element with respect to discharge route.

Preferably, the valve element has internal thread, and this internal thread cooperates with outside thread on being located at throttle element.Therefore, well utilized for the space of using in the inside of radiator valve.

Description of drawings

By preferred embodiment the present invention is described below in conjunction with accompanying drawing.Here:

Fig. 1 shows first kind of mode of execution of radiator valve;

Fig. 2 shows second kind of mode of execution of radiator valve;

Fig. 3 shows the third mode of execution of radiator valve.

Embodiment

Fig. 1 shows the radiator valve 1 that form is a built-in valve.This radiator valve 1 has housing 2, and this housing can screw in the heater that is not shown specifically with outside thread 3.Valve base element 5 is inserted and secured in this housing 2 from end face 4.Here, this fixing for example can or being pressed into by screw-in be realized.This valve base element 5 has inlet passage 6 and discharge route 7.Inlet passage be annular and surround discharge route 7.Inlet passage 6 has the passway that forms valve seat 8.

Valve element 9 cooperates with valve seat 8, and when radiator valve 1 was closed, this valve element was close on the valve seat 8 by Sealing 10.Valve element 9 is operated by tappet 11, and this tappet and valve element 9 are integrally formed.This tappet 11 by spring 12 by pretension on the open position of radiator valve 1.Operative pin 13 works along closing direction, and this operative pin is outwards drawn by gland 14.This operative pin 13 is normally loaded by constant temperature valve gap (not being shown specifically), to block radiator valve 1 stronger or more weakly.

Tappet 11 can be directed in tappet stem guide 15 in the axial direction movably.But this tappet keeps antitorque commentaries on classics in this tappet stem guide.For this reason, engaging piece 16 in this tappet stem guide for example has, engaging piece cooperates with corresponding outer gearing portion 17 on being located at tappet 11 in this.The antitorque commentaries on classics of tappet stem guide 15 ground is connected with follower 18, and this follower stretches out from housing 2 on an end relative with end face 4.Follower 18 is connected with operation ring 19 antitorque commentaries on classics ground again, thereby when operation ring 19 rotated, tappet 11 and then final valve element 9 also can rotate.

Discharge route 7 extends in throttle element 20 towards the valve element, and this throttle element is designed to pipe fitting and integrally formed with valve base element 5.This throttle element 20 inserts in the valve element 9.In any case this also partly is used for the guiding of valve element 9.

Throttle element 20 has opening 21, and this opening is arranged in the peripheral wall of throttle element 20 and starts from the end of throttle element 21 towards tappet 11.Valve element 9 has window 22.Opening 21 and window 22 all are to extend on the part of the periphery of throttle element 20 or valve element 9.

Be arranged in the housing 2 to throttle element 20 fixed-site.On the contrary, valve element 9 not only can move on the offset direction of tappet 11, and can rotate by this tappet 11.By the rotation of valve element 9, can change the level of coverage between opening 21 and the window 22 with respect to throttle element 20.If this level of coverage maximum will be opened maximum flow cross section so.If this level of coverage minimum, so mainly the preset that is made of valve element 9 and throttle element 20 has its maximum throttling action also therefore farthest to have limited the flow of heat transport fluid, and this flow is by arrow 23 expressions.

Preset can be regulated from the outside by rotating operation ring 19.In case of necessity, on operation ring 19, can be provided with mark 24, with the position of indication window 22.Then, which peak rate of flow the preset that comprises valve element 9 and throttle element 20 from the outside as can be seen is adjusted to.

If valve element 9 promotes from valve seat 8, on the end face of tappet 11, form the inflow cross section that enlarges a little more precisely at throttle element 20 so.But this expansion can be considered in advance.

Fig. 2 is at a kind of mode of execution through changing that shows radiator valve 1 on the diverse location of valve element 9 and on the diverse location of

preset

9,20.

Identical or corresponding parts use the reference character identical with Fig. 1 to represent.

In the mode of execution according to Fig. 1, throttle element 20 is fixedlyed connected with valve base element 5 and then with valve seat 8, and now, throttle element 20 just also is connected with valve base element 5 by moment of torsion support 25.That is to say that this throttle element 20 is removable in the axial direction with respect to valve base element 5, but can not be rotated.

Valve element 9 is provided with internal thread 26, and throttle element 20 is provided with outside thread 27.If valve element 9 is rotated by tappet 11, throttle element 20 is offset in valve element 9 so, shown in the comparison of for example Fig. 2 a and 2c.Therefore, in the axial direction level of coverage is changed between opening 21 in the throttle element 20 and the window 22 in the valve element 9.In the position of the throttle element shown in Fig. 2 a and the 2b 20 with respect to valve element 9, the throttling action minimum of preset.In the position with respect to valve element 9 of the throttle element shown in Fig. 2 c and the 2d 20, obtain the less axial level of coverage between window 22 and the opening 21, thereby obtain corresponding bigger throttling action.

At Fig. 2 a, during the little throttling action of passing through that valve element 9 and throttle element 20 form shown in the 2b, as by shown in the arrow 23, heat transport fluid can be at both direction, promptly radially inwardly and radially outward, flows out by valve seat 8.Yet, when radially inwardly flowing out, can not be subjected to the throttling action of preset.

If preset is subjected to throttling more strongly, that is to say that throttle element 20 further is pushed in the discharge route 7, this can seem different.Here, later at valve element 9 when valve seat 8 promotes, throttle element 20 also can be drawn out a little from discharge route 7.But throttle element 20 has the end face 28 of cutting sth. askew, thereby fluid can only radially inwardly overflow by valve seat 8 on the part of periphery.Place in throttle element 20 still is arranged in discharge route 7 has stoped fluid radially inwardly to cross valve seat 8 and has overflowed.

Fig. 3 shows the third design proposal, and in this scheme, identical or corresponding parts use the reference character identical with Fig. 1 and 2 to represent.

The design proposal of Fig. 3 and the difference of Fig. 2 mainly are: internal thread 26 is more or less on the whole inner length of valve 9 and extends, and wherein, 9 of valve elements have several arms that become star arrangement, and these arms are supporting and encircling 28, are fixed with Sealing 10 on this ring 28.But here, preconditioning also is to influence by dual mode.On the one hand, can change window 22 in the valve element 9 and the axial level of coverage between the opening 21 in the throttle element 20.On the other hand, when changing throttle element 20 with respect to the height of valve element 9, throttle element 20 also is drawn out from discharge route 7 more or less with its end face of cutting sth. askew 28, thereby the end face of cutting sth. askew 28 is opened the bigger or less periphery of " inner " valve seat 8 for overflowing of heat-carrying agent 23.
