The valve element is installed for displacement between first working position and second working position. In first working position the valve element engages with thefirst seat, and in second working position, with the second seat. A valve spindle which is angled about a predetermined angle opposite a central axis of the valve seat housing. Thereby overall dimensions of valve and space required for arrangement of such valve is reduced.

Description

Valve, particularly radiator valve
Technical field
The present invention relates to a valve, particularly a radiator valve has a valve element and a valve seat housing that is arranged on the valve rod, and the valve seat housing has one first valve seat and one second valve seat; Wherein, the valve element can be mutually adjusted between second working position that first working position that valve element and first valve seat concur and valve element and second valve seat concur.
Background technique
This valve has obtained open in DE 100 48 688 A1.
On radiator valve, generally predesignate through-flow direction.This through-flow direction should be noticed that so that avoid fault, this fault can be discovered by abnormal noise especially.Fluid should pass valve seat flow valves element.Under the situation that through-flow direction is not noted and valve is installed by mistake, fluid just flows to valve seat from the valve element.When valve cut out, the valve element was just moved towards valve seat, and avoided the gap between valve element and the valve seat.When this gap is lower than certain size, to close to valve element impact type, this brings a unexpected pressure to raise in the pipe-line system that valve is installed.This pressure raises and is called as so-called " water slug " (Wasser-schlag), and it not only brings abnormal noise, and can cause the damage in the pipe-line system.
The danger that the radiator valve mistake is installed is not only because the professional qualification deficiency of installation personnel is brought, and, when people can not clearly confirm in old house or equipment, which circuit is used to flow into hot water, when which circuit is used to flow out hot water, the danger that also can exist the radiator valve mistake to install.
Therefore from the known situation of DE 100 48 688 A1, be provided with two valve seats.Like this, it at first is inapparent with which kind of the installation of carrying out valve connect being set.If when determining which valve seat to flow into fluid to be controlled, then can come the valve element is positioned by rotate a housing member with respect to the valve seat housing by, thus make it just and valve seat concur, fluid is by this valve seat inflow.But this has brought following consequence, and just valve is relatively large.Must provide one to be the space of actual requisite space twice, because in use, the valve element should be fixed on two different positions.
Summary of the invention
Purpose of the present invention is exactly on a kind of such valve, to keep little space requirement.
This purpose can be started the valve realization of the sort of form of mentioning by article, and just valve rod is with respect to predetermined angle of medial axis inclination of valve seat housing.
With this design conserve space significantly.Particularly the space requirement of actuating valve needs dwindles.When valve rod tilts, driving structure, usually be exactly that a gland just can continue to be moved " to middle " together with valve follower and a shell dimension, a driving element for example thermostat valve cap can be fixed on the described driving structure, thereby, driving mechanism more or less be in the position of not depending on the valve element on the same position.Need obviously littler space.
Preferably, valve rod has a drive end, and it terminates on the medial axis.In this case, even can be in that " " center " is arranged driving mechanism, thereby it is located on the same axis with the medial axis of valve seat housing.Under these circumstances, when adjusting, the valve element in fact do not have the additional space demand.
Preferably, each valve seat is with respect to the predetermined angle of plane inclination perpendicular to the medial axis.People can be provided with the valve element perpendicular to valve rod to previous the same, thereby when the valve element is when the direction of valve seat rises or descends, always can keep an identical shaped gap at the periphery of valve element.This has favorable influence to the flow characteristic in the valve.The only monolateral minutely load that is subjected to of valve element at first.This has just prolonged the working life of valve.By the inclination of valve seat, make when cut-off valve, just when being placed on the valve seat, can always more or less act on an identical power in a circumferential direction to the valve element.This valve can be sealed shut with a less comparatively speaking cost.
Preferably, valve rod can drive push rod by one and load, and it becomes an angle less than 180 degree with valve rod.Thus, valve rod and driving push rod be not just on a straight line.This neither be essential, an enough power can be delivered on the valve rod as long as drive push rod.
Preferably, drive push rod and for all positions of valve element, occupy an identical position.This just means that for example, the axis that drives push rod is coordinated mutually with the medial axis of valve seat housing.In the time of the change in location of valve element, do not cause driving the variation of push rod, therefore just do not cause yet thermostat valve cap standing part geometrical relationship (Befestigungsgeometrie) variation or move.This valve keeps the outside not change, and where does not depend on the valve element simultaneously, just, does not depend on that valve element and which valve seat concur.
Preferably, valve rod is connected with the driving push rod by a joint connection.This joint connection is designed to simpler relatively.For example, driving push rod is embedded in the recess of an arch on the valve follower end face.Such joint connects permission, and the valve element successfully moves on to another working position from a working position, and does not lose and drive the acting in conjunction between the push rod.
Preferably, the valve element can be adjusted by the rotation of an auxiliary device.People needn't directly act on the valve element.This has the following advantages, and promptly valve totally needn't be opened in order to adjust the valve element.Valve just can keep sealing with a bigger reliability like this.
Preferably, auxiliary device is made of a guide mechanism, and valve rod is bearing in wherein, so people need only rotary steering mechanism.This can easily realize from the outside.
Preferred thus guide mechanism has the guide channel of an inclination.This guide channel has more advantage.One, it guides valve rod in one of shaft length relatively large scope.In addition, when valve element adjustment campaign, valve rod is supported on the relatively large area, thereby does not just worry the valve rod distortion.
Preferably, auxiliary device and valve seat housing have a coefficient positioning device, and by this device, the valve element only is positioned on the predetermined working position with respect to the valve seat housing.This is fixed on its working position valve element and is more prone to.People must rotate auxiliary device, up to being stuck or the backstop positioning device on one or another direction.
Preferably, auxiliary device can drive from the outside by a control loops.This control loops has just been simplified operator's effect.Control loops can be touched easily from the outside and the value of valve outside dimensions is obviously enlarged.
Preferably, control loops is surrounded a gland housing.Thus, control loops has an additional function.It can protect the gland housing not to be hurt from the outside.
Preferably, the valve element has the lift height restriction that can regulate.Can realize for example preliminary adjustment of valve by this lift height restriction.The example of this lift height restriction has obtained description in DE 10,022 730 A1.
When advantageously the valve seat housing has the end face opening that a lateral opening that is communicated with first valve seat and is communicated with second valve seat.This valve can be used as an alternative of traditional built-in valve.
Description of drawings
Together with accompanying drawing the present invention is described below by preferred embodiment, in the accompanying drawing:
Fig. 1 valve shown in section;
The part of Fig. 2 valve is together with the 3-D view of its auxiliary device;
Fig. 3 valve seat housing is together with the zoomed-in view of valve element;
The three-dimensional zoomed-in view of Fig. 4 valve seat housing.
Embodiment
Radiator valve 1 has housing 2, and this housing has outside thread 3, can be screwed into radiator valve on the radiator that is not shown specifically by it.Correspondingly, radiator valve 1 just is made into built-in valve.
Housing 2 is connected with a valve seat housing 4, and this valve seat housing has one first valve seat 5 and one second valve seat 6.As can be seen from Figure 3, first valve seat 5 is connected with an opening 7, and this opening is formed on the peripheral wall of valve seat housing 4, and the opening 8 of second valve seat 6 and an end face is connected.
Internal placement at housing 2 has a valve element 9.Valve element 9 is fixed on an end of valve rod 10.Valve rod 10 is supported in the guiding device 11, and this guiding device has a guide channel 12.Guide channel 12 guides valve rod on the major part of valve rod 10 length.Guide channel 12 is extended to a recess 13 on away from an end of the guide channel 12 of valve seat housing 4, one spring wherein is set in a not shown manner, spring is pressed onto on the open position at the following valve rod 10 of the situation that does not have external force, and valve element 9 lifts from valve seat housing 4 on this open position.This spring action is on an annular flange flange 14 of valve rod 10.
As can be seen from Figure 1, valve rod 10 tilts with respect to the medial axis 15 of valve seat housing 4, and this medial axis also constitutes the medial axis of housing 2.Valve rod 10 finishes with a drive end 16 away from valve element 9 on medial axis 15.It has the recess 17 of a rounding there, has a driving push rod 18 to extend in the described recess.Driving push rod 18 is coaxial with medial axis 15, thereby drives push rod 18 with an angle less than 180 degree is just arranged between the valve rod 10.Angle together with valve rod 10 and medial axis 15 obtains 180 degree.
Push rod 18 penetrates a gland 19, and this gland is disposed in again in the gland housing 20.Gland housing 20 by a Sealing 21 for example a circular seal ring remain on hermetically in the housing 2.Gland housing 20 rotatably is fixed in the housing 2.
Gland housing 20 is surrounded by a control loops 22, and the people can catch this control loops from the outside, so that with respect to housing 2 rotation gland housings 20.Gland housing 20 also has a torque face 23 in addition, and the people can be placed in instrument on this face, so that adjust gland housing 20 with respect to housing 2.
Gland housing 20 is connected with guiding device 11 by a synchronizer 24.Therefore when gland housing 20 was rotated, guide mechanism 11 was rotated simultaneously.Counterpart 25 is arranged, they and synchronizer 24 actings in conjunction on the guide mechanism 11.Synchronizer 24 and its counterpart 25 are arranged on mutual opposed of guide mechanism 11 suitably.
When guide mechanism 11 was rotated, it just drove valve rod 10 naturally and rotates together.Just move on to second working position at this valve element 9, valve element and 5 actings in conjunction of first valve seat on described first working position, it and 6 actings in conjunction of second valve seat on second working position from its first working position.For valve element 9 is moved on to another working position from a working position, must be on the principle gland housing 20 Rotate 180 degree.Housing 2 is with respect to valve seat housing 4 fixed-site.But also may make housing 2 is rotatable with respect to valve seat housing 4, thereby in housing 2 rotation together too when first valve seat 5 is adjusted to second valve seat 6 of valve element.
Space 17 connects by the joint that the end that drives push rod 18 forms the ball-joint form.This ball-joint bears when valve element 9 motion the motion that produces along the direction of (aktiv) valve seat 5,6 of each activity.This joint connects the motion of also bearing when valve rod 10 is adjusted in a circumferential direction in addition.
As for example from Fig. 2 and Fig. 4 as can be seen, valve seat housing 4 is not flat in the side towards valve element 9, but V-type wherein has a relatively large angle between two of V-arrangement limits.Arrange this two limits, make when valve element 9 and valve seat concur that two valve seats 5 and 6 are separately perpendicular to valve rod 10.In other words, just these two valve seats 5 with 6 with respect to one perpendicular to one of the plane inclination of medial axis 15 as valve rod 10 with respect to the angle the medial axis 15.Therefore possible is, valve element 9 always vertically along the direction of each valve seat 5,6 towards or move with lifting off a seat, wherein between valve element 9 and each valve seat 5,6, always form one and be evenly distributed the gap, ground at circumferencial direction.Valve rod 10 impacts can in the practical application closing property of valve with respect to being tilted in of medial axis 15.
In order to guarantee valve element 9 with respect to desirable valve seat 5,6 correct positioning separately, valve seat housing 4 has a recess 26 at it on a side of guide mechanism 11, and the protuberance 27 of guide mechanism 11 is embedded in this recess.Guide mechanism must rotate with certain power, so that make protuberance 27 leave its recess 26.When leaving this position, rotate with the continuation that a little power just can make guide mechanism 11 carry out subsequently.But this can most clearly perceive for the operator, arrives " correctly " position (just valve element 9 is opposed with another valve seat 5 or 6), because at this moment protuberance 27 just can be snapped to 26 li of recesses again.
Another kind of scheme is shown in Figure 4.Here guide mechanism has a protuberance 28, and when valve element 9 was located with respect to first valve seat 5, this protuberance leaned against on the chock spare 29.For second valve seat 6, a similar retainer (invisible) is set on opposite side.Valve seat housing 4 towards a side of guide mechanism 11 in the front of retainer 29, a guide surface of cutting sth. askew 30 is arranged.The inclination of this guide surface 30 can be consistent with the inclination of second valve seat 6.But this is not certain essential.
In a kind of unspecified mode, people also can be arranged on gland housing 20 in the housing 2 by screw thread, thereby when rotated, it changes its axial position with respect to guide mechanism 11.Thus, the change of a lift height or the restriction of lift height just can be implemented, and it can be used to pre-set valve 1.Certainly imagine other the scheme that pre-sets.
