Description
Technical field
The present invention relates to be used for the connection valve of radiator, it has a shell, radiator mouth and at least one supply opening that can link to each other with a supply line that at least one can link to each other with a radiator.
Background technology
From DE29812233U1, known such connection valve.
Main with wall radiator (radiator) and especially use such valve that is connected relevantly with the towel dryer.Such radiator often no longer directly promptly links to each other with the current drainage pipeline for the stream pipeline with supply line.Exactly, with to be connected valve continuous, a radiator valve such as hot control radiator valve can be installed in this connection valve for stream pipeline and current drainage pipeline.Can on radiator valve is pre-installed, connect valve, thereby can successfully carry out all the other installment works such as assembly wall sheet in relevant room.Subsequently, in the suspension radiator and with its be connected valve and couple together.
But radiator is relatively more bothersome with being connected the valve connection.What adopt in the described example of DE29812233U1 is locking nut, by locking nut valve is linked to each other with corresponding radiator pipeline.This for example needs the radiator pipeline to have suitable length and is equipped with the conical surface.
Summary of the invention
Task of the present invention is to simplify installment work.
In the connection valve of the above-mentioned type, so finish above-mentioned task, promptly be provided with a fixing hole on the opposite of each radiator mouth, a stationary pipes is passed described fixing hole, and described stationary pipes is projected into outside the radiator mouth by fixed mechanism.
Can connect formation connection between valve and the radiator simply by stationary pipes.For this reason, only need insert stationary pipes or be screwed in the respective aperture in the radiator just.In this case, also can be from the shell opposite side near stationary pipes, thus the operation of stationary pipes is fairly simple.Radiator itself does not hinder this installation.The operation of stationary pipes has had the space of enough usefulness.
When fixed mechanism had one section screw thread or locking geometry, this also was favourable.Can produce being threaded between stationary pipes and the radiator by one section screw thread.But when corresponding formation radiator, can realize that also quick-action connects.
In this case, stationary pipes is preferably in the fixing hole zone and abuts on the shell sealedly.This sealing for example can realize so simply, and promptly stationary pipes links to each other with an annular lip on that end of fixing fixing hole, and described flange perhaps abuts on the shell under the centre is provided with the situation of seal.But, can certainly be susceptible to the conical surface shape widening portion of other geometry design scheme such as stationary pipes.Stationary pipes also not necessarily will be connected with outer casing screw.If stationary pipes is screwed in the radiator by its thread segment, this is just enough.Be enough to opposite shell sealed heat-dissipating device and also opposite shell sealing and fixing pipe by being screwed into the suffered pulling force of the shell that causes.
Stationary pipes is preferably in has a torque face on that side of fixing hole.Therefore, can apply power from the fixing hole side to stationary pipes, thereby can it be screwed in the radiator with required torque with instrument.
Stationary pipes has a cinclides in its tube wall in the middle of being preferably in shell, and described cinclides links to each other with supply opening.By this cinclides, also can form the fluid course of the heat transport fluid from the supply opening to the radiator simply.Because cinclides is arranged in the shell in other words in the stationary pipes part that is positioned at shell central authorities, so sealing problem is unessential.
Shell is preferably in the cinclides zone with fixing hole has cannelure.It is unessential that stationary pipes finally is installed in the shell with the position, angle of assorted petty sample.Stationary pipes can only be screwed into the radiator from fully fixing angle with seeing.Guaranteed that fluid is admitted in the stationary pipes.
In this case, the stationary pipes lateral surface has one cannelure in the cinclides zone, and this is particularly preferred.Can be obviously more easily be formed on groove on the lateral surface than the groove on the inwall of hole.This has simplified manufacturing.
Stationary pipes preferably and the radiator mouth conjointly be surrounded by a spacer sleeve.The spacer sleeve that also can be called as cushion block can make and be adapted to different mounting conditions simply and become possibility.If which kind of reason all departs from slightly radiator has been installed with connecting valve, then can have so been overcome this departing from simply, promptly people adopt slightly long stationary pipes and corresponding spacer sleeve.Exactly, need other seal in this case, promptly the sealing between spacer sleeve and shell, also need the sealing between spacer sleeve and the radiator.But, because stationary pipes can be screwed in the radiator by enough big moment, so do not realized to too big problem being tightly connected and being tightly connected between spacer sleeve and the radiator on the other hand between one side spacer sleeve and the shell.
Stationary pipes is preferably in has a closure wall that has a hole in its end region, described hole is closed by an accessory.This hole for example can be used to the emptying radiator.
But such design is particularly preferred, and promptly accessory becomes the functor form.People can make valve have other function by inserting this functor simply.Such functor for example can become forms of sensor, so that measure temperature and/or flow.But functor also can become radiator or heating form, and they are electronic.Thereby, only need reach in warm summer as people in can be during making continuous heating equipment out-of-work and add heat radiator, so that the oven dry towel.
In this case, accessory is preferably charged into stationary pipes by a convex shoulder, and convex shoulder has formed the slit each other with tube wall.Such project organization is to be beneficial to the thermal conductive surface that provides enough big especially in radiator.
Stationary pipes has in one pipe, the inner chamber that circumference of cannon bone lays out in quilt and together the slit between interior pipe and tube wall have the connecting portion that separates that is used for supply opening.In this case, as long as unique radiator mouth has been set,, realized supplying heat transport fluid and therefrom discharging heat transport fluid to radiator by described radiator mouth.Such design is particularly useful for the tandem heating equipment.
In this case, be preferably in bypass passageways of arrangement in the shell.Bypass passageways allows part heat transport fluid to continue to flow to next radiator, and does not flow through and be connected the radiator that valve links to each other.Therefore, a plurality of radiators for being arranged in same column can adjust desirable temperature regime.
Be preferably in a stopper that can take out is set in the bypass passageways.This stopper can be changed by another stopper, thereby can make the low identical connection valve of cost be matched with the diverse location of the radiator in the tandem heating equipment.In last radiator, people can close bypass passageways fully.In above-mentioned connection valve, people are provided with the stopper with either large or small throttling function.
Preferably bypass passageways is closed by a closing cock near a supply opening, and described closing cock can move in the shell always, has disconnected connection between supply opening and the stationary pipes up to it.Sealing is plugged with two tasks, and one allows near stopper, thereby can completely or partially open or block bypass passageways.Its two, it also is used to disconnect radiator and exactly is the radiator mouth and being connected of corresponding supply opening.If can seal another supply opening by radiator valve, then locking flows into or flows out fully.People also can disconnect to the radiator supply heat transport fluid that links to each other, thereby can pull down radiator.
Supply opening preferably is communicated with bypass passageways by an additional channel.Thus one, therein be connected the radiator that valve links to each other and break away from fully under the above-mentioned situation of supply, follow-up radiator still can obtain abundant heat transport fluid.
The radiator mouth preferably is made like with fixing hole.If necessary, people also can rotation cases and are made stationary pipes insert fixing hole and be exposed at outside the fixing hole.So, obtained the high flexibility in the installation.
Shell preferably by a casing cover round, described casing cover has the hole on two opposed tegmental walls, they are round stationary pipes.In many designs, from angle attractive in appearance, it is desirable covering shell with casing cover.For example, casing cover can have the color identical with radiator, and the shell of being made by brass usually has another kind of color.The fixing of casing cover can so realize simply, i.e. also fixed housing lid of stationary pipes.For this reason, only need casing cover to have the hole just, can be fixed hole and radiator mouth of described hole blocks.When sending out shell when stationary pipes is packed into, lid also is fixed on the shell.If the employing spacer sleeve, then spacer sleeve has the color the same with casing cover and perhaps the same color may be favourable with radiator.As long as load is suitably feasible, then people can stipulate, form spacer sleeve and casing cover with same material at least on its surface separately.
Casing cover is laterally being pulled on the shell along the stationary pipes bearing of trend preferably.Therefore, only need stationary pipes, on shell, move to prevent casing cover.In addition, casing cover is fixed on the shell by its shape.
In this case, the best cross section of casing cover becomes U-shaped ground to be formed with two supporting legs, and its free end curves inwardly and reserves a seam, and the width of seam equals the outside dimension of supply opening.In this design, realized as much as possible casing cover being fixed on the shell by the interior curved free end of supporting leg.Casing cover can only move at the shell upside.When stationary pipes is screwed into shell, hindered this sidesway.
