Description

[Detailed description of the invention] Heating valve The invention relates to a heater valve of the type according to the preamble of claim 1, wherein the heater valve is vertically Seated or tilted seating system with multiple radiators and various passages. It is inserted into the thermal device, primarily into the return passage.

The corresponding part of the device is discharged through such a heater valve that serves to close the passage. Ru.

The heater valve of the type mentioned at the beginning is registered as a utility model of the Federal Republic of Germany under No. 7111825. It is known from the specification of No. In this heater valve, the threaded connection of the casing A hollow spindle, which is also used for pre-adjustment of the flow rate, is screwed into the , because this spindle is closed against the valve seat of the casing through a screw cap is movable for adjustment and preconditioning. A spherical valve is placed inside a hollow valve spindle. The passage or radiator is discharged through this spherical valve. hollow valve From the outside through the spindle, the sphere returns to the spring using a screwable ejector. is moved against the pressure of the valve and thus away from the valve seat inside the valve spindle.

The front part of the valve spindle is used for presetting.

By appropriate pre-adjustment in each passage using such heater valves, the required Operating conditions are taken into account.

However, operating conditions often vary in large equipment, resulting in One time preconditioning of the flow is not sufficient. Usually a control valve is installed at the corresponding point later, at least A diaphragm regulator is also installed. This type of later installation requires an expensive assembly. Requires an included fee.

The object of the invention is to improve a heating valve of the type mentioned at the beginning so that the heating valve has a simple form. The purpose is to make it possible to combine it with a pressure regulator in a formula.

The object of the invention is that in a heater valve of the type mentioned above, the second hollow valve closing piece is double-operated. the first valve closure piece with its end facing away from the discharge valve seat; The second valve closing piece is movable through the casing in the direction of the valve seat and is attached to the heater valve. The problem was solved by making it possible to install a regulator that acts on the problem.

Heating according to the invention that can be used as a closing valve with discharge function and preadjustability For control valves, the regulator is not attached to the valve casing or upper part. will be installed on the In this case, the regulator is connected to the hollow valve spindle with the corresponding actuating member. and acts on the second valve closing piece within this valve spindle. follow The heater valve can be changed to a control valve in a simple manner.

An advantageous embodiment of the invention according to claim 2 provides that the regulator is located outside the valve spindle. is attached to the end of the It is therefore advantageous if the regulator is independent of the casing. Different casings in type but size with same shaped valve spindle end According to another embodiment of the invention according to claim 4, the preconditioning device is used for different valves. is formed so that it can be seen from the outside. Based on claim 5, the screw cap and the indicator The ring forms a preconditioning indicator visible from the outside.

The invention will now be described in more detail on the basis of the illustrated embodiment. FIG. A vertical cross-sectional view of a heater valve configured as a chain valve, Figure 2 is based on Figure 1 (heater valve and Figure 3 shows the combination with a diaphragm regulator mounted on the valve spindle.

First, FIG. 1 will be described. Reference numeral 1 is attached to the casing of the heater valve. Ke Connections 11 and 12 are shown facing each other on the housing 1, and the connections are connected to pipes or pipes. leads to the radiator. The threaded connection 13 is a screwable receptacle of the valve upper part 2. It is used for storage purposes. A valve seat 14 is formed inside the casing 1. , a first closing piece 4 arranged on the valve spindle 3 acts against the valve seat. original In theory, the adjustment of the first closing piece 4 relative to the corresponding valve seat 14 is a precondition for the flow through. It will stipulate the section. The heater valve can be closed by means of the first closing piece 4 .

In the hollow chamber 31 in the axial direction of the valve spindle 3, a double action is performed against the pressure of the spring 6. A second closing piece 5 for the purpose is slidable. The upper closing end 51 of this closing piece is in the middle. Together with the valve seat 33 in the empty valve spindle 3, a discharge valve is formed. Not shown By attaching the discharge device, the closing end 51 of the second closing piece 5 is separated from the valve seat 33. It is possible. A second closure where the water is hollowed out from the conduit or radiator for discharge. through the piece 5 into the hollow chamber 31 of the valve spindle and then from there to the outside. Flows into the ejector. The hollow chamber 53 of the second closing piece 5 opens towards the casing. and ends below the closed end 51, so that in the state shown in FIG. Valve seat 33 is closed.

The opposite closing piece end 52 projects outwardly through the first valve closing piece 4 and has a projecting section. thereby forming the contour of the first closure piece and defining, together with the first closure piece, an aperture gap. There is. The end of the valve spindle 3, which projects from the upper valve part 2, rests on the rotation entrainment 32. The screw cap 8 is non-rotatably mounted and the cap is tightly mounted on it. 82, which at the same time holds the hollow valve spindle 3. It's closed.

Pre-adjustment is carried out after removing cap 82 and screw cap 8. in this case , the valve spindle 3 is not allowed to move. A corresponding rotation of the indicator ring 7 is then carried out. and a toothed preadjustment nut located in the indicator ring 7 via the indicator ring. 10 is moved together with an adjustment ring 10a non-rotatably received therein, and the valve The spindle 3 is driven axially. Due to the corresponding rotary entrainment connection, the upper side of the valve 21 is used in this range in conjunction with a corresponding configuration of the valve spindle 3. ing. A threaded section 22 is formed on the outside of the valve upper part 2, into which a finger can be inserted. The indicator ring 7 is engaged.

As shown in FIG. 2, a correspondingly constructed cap 82 of the valve spindle 3 is At the outer end, which is provided with a section 34 which is also used for receiving, there is a regulator, preferably a dagger. Earphragm adjusters 9 can be installed. In this case, the associated threaded sleeve 91 It has plunged into the step part of Jika Tsubu 8. The adjustment member is a diaphragm adjuster. Attached to the diaphragm is a tube-shaped operating member 92, which is hollow. into the valve spindle 3 and acts with its free end on the second closing piece 5. are doing. The closing end 52 of the second closing piece 5 is connected to the casing 1 via the operating member. It is moved in the direction of the valve seat 14 and is adjusted thereby to control the flow through.
