Description
Technical field
The present invention relates to a kind of heat exchanger valving, Radiator valve door device particularly, have one and be installed in valve, a valve element and this valve seat acting in conjunction between an inlet and the outlet and that have a valve seat, also be with a pressure regulator, it makes valve pressure keep constant, and wherein pressure regulator has a unlatching spring.
Background technique
Become known for the valving with this feature of a lot of application purposes by WO 01/,130 17 A2.
By US 6 062 257 known alternative valve devices.It for example is used in the heating plant, and wherein many heating units are serially connected on the same heat supply pipeline.Pressure regulator remains unchanged the pressure on the valve, makes the influx that is connected other heating unit on the same pipeline can utilize the control characteristic of valve to keep smallerly.
By US 5 860 591 known a kind of similar valvings.
Yet bring with common heating body thermostat valve in the improvement that known case lower valve device is regulated possibility and to compare bigger physical dimension.This makes this principle implement to become difficult on market, although it has certain advantage.
The present invention also can be used in other heat exchangers, for example the occasion of covering in cooling.Heat-loading body is given heating unit with heat delivered in heat exchanger, there distribute heat towards periphery.At the occasion heat-loading body of cooling lid from absorbing heat on every side and with its output.Usually adopt water as heat-loading body.But also can use other fluids.
Summary of the invention
The objective of the invention is, can design such valve compactly.
This purpose realizes by such method in the heat exchanger valving of the described type of beginning, promptly opens spring and is arranged in the runner that heat transport fluid flows through pressure regulator.
Because the unlatching spring of pressure regulator is arranged in the runner of heat transport fluid, only need less additional structure space for pressure regulator itself, if also need.
If valve element and pressure regulator are arranged on not ipsilateral of valve seat, also be favourable.At first can make valving design compactly with this structure.On a side relative of valve seat, there is certain space usually, can be used, so that the setting pressure controlling device with valve element.Another advantage is that intrinsic Radiator valve and the pressure regulator be made up of valve element and valve seat are separated from each other.That is to say the force transfer element that permanent action is not set between valve and pressure regulator, as spring or bar.Therefore two interactional possibilities of parts are very little.
Pressure regulator is preferably disposed on before the flow direction valve seat that exports from entering the mouth to of edge, and the valve element is arranged on after the valve seat.Make the absolute pressure that acts on the valve element become less thus.Thereby can adopt the operation equipment of less less expensive.The power that thermostatic element must produce when adopting the constant temperature method device can be selected smallerly.This makes again can adopt less thermostatic element, and it can be reacted fast to temperature variation usually.The outward appearance of comparing valving with common heating body valve almost can remain unchanged.The standing part geometrical shape that for example is used to operate tube head seems can be just the same with the heating body valve that adopts on market.Valve rod particularly, just the part of operating valve element can be stretched out from housing as valve up to now just the samely.This just helps promoting this new scheme on market.
Pressure regulator preferably has the modulating valve with a regulating valve seat and a modulating valve element, and the modulating valve element is installed between regulating valve seat and the valve seat.Modulating valve element and regulating valve seat acting in conjunction, and more or less by valve controlling liquid flow.Here the motion for the modulating valve element only needs smaller structure space, anyway can provide such structure space on a side that matches with pressure regulator of the valve seat of valve.
The modulating valve element preferably has a dottle pin, and it acts on the valve element and produce a minimum range between modulating valve element and valve element.Spacer ring prevents, at pressure reduction hour, at this moment modulating valve element high lifting from the regulating valve seat makes the valve element owing to other influences are closed.If very near regulating valve seat, dottle pin can not remake and be used on the valve element modulating valve element so.But act in this case on the valve element that the valve element is pressed is bigger from the pressure of valve seat.
Valve seat is preferably disposed in the housing, and housing is processed from two mutual back-to-back sides of valve seat.Can produce the standing part geometrical shape of the operation equipment that is used for valve like this from a side, produce the standing part geometrical shape that is used for pressure regulator from opposite side.Therefore valve and pressure regulator are mechanically thrown off mutually.
Valve seat preferably constitutes a constituent element of housing.That is to say and to process the add-on parts that is used for supporting valve seat.
Pressure regulator is preferably made the assembly that is fixed in the housing.Can adopt identical assembly for dissimilar valves, for example in corner valve, throughway valve, H shape part or the like.Here H shape part is meant such element of construction, and it has the pipe joint of the supply line of the input output pipe that is used for building one side (flowing forward and reflux line) and heating unit one side, and has valve usually.If necessary, assembly can be changed easily.Therefore pressure regulator also can be complementary with different requirements.
Assembly preferably has a cavity, and it is communicated with outlet by a passage at least one opening on its wall and the housing, and its hollow cavity is surrounded by a diaphragm, and this diaphragm is connected with the modulating valve element.Pressure in effect exports on diaphragm one side like this.Pressure on opposite side in the effect inlet.This pressure also acts directly on the modulating valve element along opening direction.Like this by selecting between effective diaphragm area and the modulating valve element effective active area corresponding area than just adjusting desirable pressure reduction roughly at least.Can otherwise finely tune.
Cavity preferably has a pressure introduction port, and it constitutes by the opening device on the annular wall, and is connected with passage by annular chamber.Therefore annular wall and the same transmission power that is used in the past, that is to say can the support pressure controlling device other parts.
Diaphragm preferably is clamped between the valve seat matrix and a fixing device that forms regulating valve seat above.Fixing device for example can constitute by annular wall.Can obtain fixing eaily thus.Here " clamping " not necessarily be interpreted as, diaphragm is pressed on the clamped position with pressure.For example diaphragm not only had been connected with the valve seat matrix but also with fixing device by bonding or other connecting means, also just enough.
The best ring seal of valve seat matrix, and have at least one entry port, it is positioned on the side that enters the mouth dorsad.Thereby avoid, liquid flows directly on the modulating valve element from inlet.Make great efforts to impel liquid at first externally to flow around the valve seat matrix from inlet, arrive cavity until it by entry port, liquid can set out therefrom and act on the modulating valve element like this.This reduces the vibration tendency of modulating valve element.
Unlatching spring to the reinforcing of modulating valve element is preferably disposed between modulating valve element and the valve seat matrix.Opening spring is the main auxiliary element that is used for determining pressure, and pressure regulator should make this pressure keep constant.The unlatching spring of for example making stage clip acts on the modulating valve element along opening direction, that is to say if there is no power, and the modulating valve element just can lift from regulating valve seat.This opens spring, as mentioned above, is installed in the runner of heat carrier fluid.That is to say that in fact it does not cause the increasing of Radiator valve structure length, that is heating body valve keeps compact.
Pressure regulator preferably has a pressure regulation device, can adjust pressure on the valve with it.That is produce an additional variable force that can change, to adjust the size that keep constant compression force.
Here preferential especially is, pressure regulation device has a preloading spring that acts on the modulating valve element, and it is bearing in one on the adjustable backstop of the distance of regulating valve seat.Can additionally change and keep constant compression force by changing the power that applies by preloading spring.
Brief description
By means of a preferred embodiment the present invention is done more detailed explanation below in conjunction with accompanying drawing.Wherein unique accompanying drawing is represented a Radiator valve door device.
Embodiment
Valving 1 has the housing 2 with an inlet 3 and one outlet 4.Establish a valve 5 at inlet 3 with between exporting 4, it has a valve seat 6 and a valve element 7.Valve seat 6 is made the part of housing 2.Valve seat surrounds an opening 8, and thermal liquid flows from 3 runners to outlet 4 that enter the mouth at it through opening.Here valve element 7 is met stream by valve seat 6.
Valve element 7 usefulness known methods are fixed on the valve rod 9, and valve rod remains on its enable possition by means of spring 10.Difference according to application purpose also it is contemplated that the valve of closing without external force, that is a NC (normally closed) valve, for example the occasion of covering in cooling.Effect one operative pin 11 on valve rod 9.It passes a stuffing box 12.If operative pin 11 is pressed in the housing 2, for example by a thermostat top cover of not representing in detail, just valve 5 is closed so.This reaches near the method for valve seat 6 more by making valve element 7.
Valve 5 has a standing part geometrical shape 13, and above-mentioned thermostat valve top cover can be fixed on above it.In fact standing part geometrical shape 13 does not have any difference with common thermostatically controlled heating body valve.
Setting pressure controlling device 14 on a side relative with valve element 7 of valve seat 6, it makes the pressure on the valve 5 keep constant.Therefore the flow that flows through valve 5 is only determined by its opening degree, that is is determined by the distance between valve element 7 and the valve seat 6.
Pressure regulator 14 has a valve seat matrix 15, and regulating valve seat 16 is installed on this matrix.Modulating valve element 17 and regulating valve seat 16 actings in conjunction, the modulating valve element is pressed from regulating valve seat 16 by opening spring 18.Opening spring 18 is bearing on the boss 19 of valve seat matrix 15.
Modulating valve element 17 is connected with diaphragm 21 by screw 20.Diaphragm 21 is fixed between a valve seat matrix 15 and the fixing device 22, and pressure regulator 14 is fixed in the housing 2 with this fixing device equally.
Fixing device 22 has a screw thread 23, and this screw thread of fixing device 22 usefulness is screwed in the housing 2.Sealing 24 stops liquid to flow out.
Fixing device surrounds a cavity 25 with diaphragm 21.Here the be fixed annular wall 26 of device 22 of cavity 25 is surrounded.Establish an opening device with many openings on annular wall, opening is communicated with passage 29 on the housing 2 by annular pass 28, this passage again with export 4 and be connected.
Valve seat matrix 15 be equally ring seal and have an entry port 30, it is not opposed with inlet 3, but is positioned at the opposite side of valve seat matrix 15.By the connection that an annular pass 31 is set up between inlet 3 and the entry port 30, the annular pass forms between housing 2 and valve seat matrix 15.Therefore the flow path of heat-carrying agent passes valve seat matrix 15, that is passes pressure regulator 14, and is to lead to regulating valve seat 16 from side opening 30.Opening spring 18 is arranged in this flow path.Therefore it need be in the additional structure space on lengthening pressure regulator 14 meanings.
Valve seat matrix 15 seals with respect to housing 2 by Sealing 32.
Diaphragm 21 is subjected to the active force of a preloading spring 33, wherein preloading spring 33 on diaphragm 21, thereby also on modulating valve element 17, apply a power, it is orientated like this, makes modulating valve element 17 be subjected to a load of leaving regulating valve seat 16.Therefore act on the modulating valve element 17 along opening direction except that opening spring 18 preloading springs 33.Its opening force component is usually less than opening spring 18.That is to say that opening spring 18 provides " basic load " or " fundamental force ", and preloading spring can be used for fine setting.Can select enough greatly or can reach fine setting if open spring 18, can cancel preloading spring 33 so with additive method for the application target of anticipation.
Preloading spring 33 is bearing on the backstop 34, and the position of this backstop in housing can be with a screw adjustment.That is to say by changing the position of screw 35 in housing 2 and can change the pretightening force that acts on the modulating valve element 17.Can certainly adopt other possibilities, change pretightening force and adjust, for example have the different pads of different-thickness or quantity.
A throttling arrangement 36 is adorned in the back of streamwise valve 5, and it flows through outlet at liquid stream and produced certain pressure drop at 4 o'clock.
There is a pressure P 1 in the ingress.There is pressure P 2 in the cavity 37 between regulating valve seat 16 and valve seat 6.There is pressure P 3 in the outlet port.
Pressure P 1 arrives valve seat matrixes 15 inside by annular pass 31, and acts on thus on the modulating valve element 17, and be by diaphragm 21 to closing direction, by modulating valve element 17 itself to opening direction (applying active force).Because the effective pressure acting surface of the effective pressure acting surface of diaphragm 21 and modulating valve element 17 is complementary, the effect of pressure P 1 is actually balance.
Pressure P 2 acts on the modulating valve element 17 along closing direction.Cause a pressure drop by the throttling position that between modulating valve element 17 and regulating valve seat 16, forms.The size of pressure drop is determined in the adjustment of spring, thereby determines the size of pressure reduction.
Pressure P 3 is because the pressure drop on the valve 5 equally may be less than pressure P 2, and this pressure P 3 acts on the modulating valve element 17 to opening direction by diaphragm 21.Throttling arrangement 36 can also have an opening 39 in addition, and in fact pressure P 3 arrives passage 29 by this opening.Throttling arrangement 36 causes the hydraulic damping in chamber 25.Opening 39 also can replace by one or several pit on the surface of contact between throttling arrangement 36 and the housing 2 simply.Throttling arrangement 36 should not produce big circulating resistance for thermal liquid with its opening (a plurality of openings can be set) yet.
Can establish a spacer ring pad on modulating valve element 17, it can act on the valve element 7, and modulating valve element 17 is distant from regulating valve seat 16 if valve element 7 arrives near the valve seats 6.If pressure reduction is little, be this situation.Perhaps have such danger in this case, promptly valve element 7 is fitted on the valve seat 6 owing to ectocine, even do not wish like this.Dottle pin 38 prevents that such situation from occurring.
