Abstract
The present invention relates to a flux or differential pressure regulating valve for regulating the fluid flux or differential pressure in medium conveying equipment. The bottom of the regulating valve is disposed with an inlet branch pipe, an outlet branch pipe and an auxiliary valve connection pipe. The auxiliary valve forms a first flux throttle point by a valve seat and an active locking member and has a presetting mechanism. The presetting mechanism forms an adjustable second throttle point connected with the first throttle point in series by the same valve seat or another valve seat. The regulating valve has a valve drive mechanism fixed on the connection pipe and/or the valve seat which has a pressure cavity formed by active clapboard and connected to a pressure transmission channel. The auxiliary valve having pressure channel and the valve drive mechanism having pressure channel can be separated from each other. The operation rod of the presetting mechanism used for changing the second throttle point can be approached only when the valve drive mechanism is disassembled. When the valve drive mechanism is assembled, the pressure channels of the auxiliary valve and the valve drive mechanism are aligned and sealed with each other and form a common sealed pressure channel.
Description
Technical field
The present invention relates to a kind of being used at the flow control valve differential pressure modulating valve of medium transport equipment as the flow differential pressure of regulated fluid in heating and cooling equipment, it has a modulating valve bottom, one inlet arm is arranged at this bottom, one outlet stool and one between them and be used for the adapter that to pack attaching valve wherein into, the attaching valve forms a first flow throttle point with the fastening device of a valve seat and an activity, this attaching valve has a preset mechanism, this preset mechanism forms second an adjustable throttle point with same or another valve seat, second throttle point is connected with the first segment flow point, this flow control valve differential pressure modulating valve has a tappet gear that can be fixed on adapter and/or the valve seat, it has some pressure chambers, these pressure chambers are made of one or more active clapboards, lay respectively at before the can regulate flow point and pressure afterwards is transfused in these pressure chambers by the pressure transmission passage, these pressure transmission passages are formed by the parts of this attaching valve and this tappet gear.
Background technique
Flow control valve with such performance has for example been described for 44 16 154 li at DE 37 41 676 with at DE.In view of the above, these flow control valves have attaching valve and tappet gear as an adjunct unit ground, and wherein, this tappet gear is the constituent element of preset mechanism, and perhaps this preset mechanism has the operator that is attached on the tappet gear parts.If tappet gear has fault such as film impaired, then need to change a whole set of adjunct unit and will from valve housing, back-out for this reason.In addition, the common ground of these flow control valves is, can be from the outside near the operator of preset mechanism.Often to avoid this accessibility, thereby, additionally need a kind of sealing and/or lead sealing or the suitably measure of capping.
Summary of the invention
In the present invention, the shortcoming of the flow-pressure differential modulating valve that these are known overcomes by the following method, having promptly that the attaching valve of band preset mechanism of pressure channel and tappet gear with pressure channel be designed to is can be separated, wherein on the one hand, the operator that is used to change the preset mechanism of second throttle point only could be approaching when tappet gear is removed, on the other hand, when loading onto tappet gear, the pressure channel of some common mutual sealings is aimed at and formed to the pressure channel of this attaching valve and the pressure channel of tappet gear mutually.
When tappet gear is loaded onto, the pressure channel that forms with the attaching valve is thus arranged, promptly before second throttle point and pressure afterwards be transfused to respectively in the chamber that separates of tappet gear, obtain a favourable form of implementation of pressure channel thus.
Another favourable form of implementation obtains by a stop surface on the part of the active clapboard of tappet gear, a valve rod that is connected with fastening device acts on this stop surface, thereby just the to-and-fro motion of tappet gear part and this valve rod by this active clapboard can be passed to fastening device.Like this, the to-and-fro motion that passes to fastening device has changed the circulation transverse section and thereby has changed flow towards valve seat ground.
Another advantageous forms of implementation of attaching valve is that the pressure channel in the attaching valve is made of the part of valve rod, preset mechanism, the shell of attaching valve and the part in the inner part that modulating valve is taken over.
A preferred implementing form of pressure channel produces by the valve rod of the localized borehole at least in the attaching valve, and this valve rod forms a common pressure channel by stop surface with the centering piece of the active clapboard of localized borehole equally at least.
For being created in the sealing of this common pressure channel on this stop surface, in the part of active clapboard, be provided with one the band Sealing to mesopore, the end that is positioned at the valve seat opposite of valve rod is loaded into this in the mesopore.
Pressure on the end relative with valve seat of pressure channel reduces point and is formed by flow cavity, the border of being somebody's turn to do is by the shell wall of inboard, a fastening device formation that forms the preset part of second throttle point and form the first segment flow point of preset mechanism, wherein, this preset part preferably have a sleeve shape to the outstanding flange of valve seat, this flange has at least one on its outer surface as the hole of throttling transverse section and with the saturating fluid ground of its ora terminalis and can be bearing on the valve seat rotatably around the longitudinal axis of this part, perhaps this preset part can axially be adjusted, thereby just forms a preset transverse section of playing throttling action between the ora terminalis of sleeve shape flange and valve seat.
For checking the total pressure situation and for the filling or this equipment of unstowing, can load onto additional adapter on flow control valve differential pressure modulating valve on this modulating valve, these adapters have and are used to measure, the functor of filling, emptying or venting.
