DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temperature control valve for a natural convection radiator used in a natural convection radiator for heating by circulating a circulating liquid heated by a heating device for heating. .

[0002]

2. Description of the Related Art Conventionally, panel convectors and radiators which circulate circulating fluid such as water or antifreeze heated by a heating device such as a heating boiler and radiate heat by the heat of the circulating fluid to heat the room. Natural convection radiator 10
In No. 1, a natural convection type radiator temperature control valve 102 for controlling the flow of the circulating liquid into the radiator 101 at room temperature was used. This is the circulation pipe 1 that constitutes the circulation path of the circulating fluid.
The opening and closing valve is opened and closed by moving the open / close valve using the volume change of the thermowax which expands and contracts due to the change in room temperature, through the flow opening formed in the blocking wall in the connection pipe 104 connecting the heat sink 03 and the radiator 101. In addition to controlling the flow rate of the circulating fluid, the desired room temperature can be set by operating the operating member 105, and when the room temperature reaches the set temperature, the flow port is completely closed by the open / close valve.

When selecting the heating capacity and size of the radiator 101, first, the heating capacity of the radiator 101 is determined by referring to the monthly average value of the daily minimum temperature at the time of the minimum temperature of the day and the desired temperature. That can heat up to
In addition, the heat radiating capacity is selected from those having a heating capacity slightly larger than the calculated load value, which is as long as possible over the width of the window 106.

This is a natural convection type radiator 101 of this kind.
Is generally installed below the window 106 so that convective heat 107 generated from the upper surface of the radiator 101 causes
6 is pushed up toward the ceiling of the room, and the cool air 108 entering from the window 106 is
6 is prevented from lowering toward the floor of the room, thereby preventing the temperature of the floor from lowering. There was no heating.

[0005]

By the way, in this conventional apparatus, first, the volume change of expansion and contraction of the thermowax does not linearly follow even if the temperature changes abruptly, but gradually changes. The outlet was gradually opened and closed over 5 minutes from fully open to fully closed, and over 1 minute from fully closed to fully open.

In most cases, the operation of the operating member on which the desired set temperature and the corresponding heating level are graduated, that is, the setting of the desired temperature, is not changed once the graduation is adjusted, and the graduation is used without change. And
If heating is performed when the temperature difference between the outside air temperature and the room temperature is small in that state, the heating capacity of the radiator that can sufficiently heat even at the lowest daily temperature will be excessive, and the distribution port will be fully closed immediately, and then fully closed. The time becomes much longer than the time when it is fully open.

Therefore, convection heat is not generated because the circulating liquid does not flow into the radiator, and the fully-closed state in which the cool air entering from the window descends steadily toward the floor surface becomes longer. The temperature suddenly drops and the temperature difference with the upper part of the room increases, and the temperature in the range of about 10 cm to 15 cm from the floor surface where the temperature control valve is installed also drops, so that the thermo wax becomes When the circulating fluid flows into the radiator again due to contraction and opening of the circulation port, the temperature near the floor surface becomes considerably low.

The diameter of the hole at the tip end portion 11 of the insertion portion 10 is made smaller than the diameter of the other portion of the sliding hole 9.

The desired temperature and heating level can be set by moving the thermosensor 1 back and forth.

Reference numeral 22 denotes a connecting member having a hollow cylindrical shape, the inner diameter near the center being partially reduced, and the outer periphery being threaded.

The upper end of the push-up spring 27 formed of a coil spring through which the shaft portion 4 is inserted comes into contact with the lower surface of the E-ring 26 of the open / close valve 24 to lift the open / close valve 24 upward. The opening and closing valve 24 stops at a position where the force and the pushing-up force of the pushing-up spring 27 are balanced.

Reference numeral 28 denotes a connection pipe, one end of which is connected to the circulation pipe, the other end of which is connected to the inflow side of the radiator. An engagement portion 29 is formed in which the threaded portion engages to fix the connection member 23, and the connection pipe 28 below the engagement portion 29 is opened and closed by the valve portion 25 of the on-off valve 24. A blocking wall 31 in which a flow port 30 is formed is provided.

The circulating fluid in the connection pipe 28 is prevented from leaking into the connection member 23 by being in close contact with the hollow portion 3.

Next, the operation will be described. First, the circulation port 30 in the connection pipe 28 is connected to the open / close valve 2 as shown in FIG.
From the state where the circulating fluid does not flow into the radiator at all because the valve unit 25 is completely closed by the valve unit 25, the operating member 19 is manually turned to adjust the scale from the fully closed state of “0” to a scale of “5”, for example. Thus, the distribution port 30 is opened.

When the operation member 19 is rotated in the fully open direction to adjust the scale, the threaded portion of the insertion portion 10 in the operation member 19 is removed from the threaded portion on the upper inner periphery of the sliding member 12. Since the member 7 moves upward, the force by which the operating rod 5 pushes down the opening / closing valve 24 becomes weaker, and the force by which the push-up spring 27 pushes up the E-ring 26 of the opening / closing valve 24 becomes stronger, so that the push-up spring 2
The opening and closing valve 24 is pushed up by the extension of 7. As a result, the valve portion 25 of the on-off valve 24 that has been in close contact with the communication port 30 in the connection pipe 28 rises, and the horizontal portion of the blocking wall 31 where the communication port 30 is formed and the distal end surface of the valve portion 25 are moved. A gap is generated, and the circulating liquid flows from the circulation port 30 to the radiator through the gap.

The opening / closing valve 24, which is moved upward by the push-up spring 27 by moving the holding member 7 upward as the degree of turning the operation portion 19 in the fully open direction increases.
The amount of upward movement is increased, and accordingly, the barrier 3
The gap between the horizontal portion 1 and the tip end surface of the valve portion 25 also increases, and the amount of circulating fluid flowing increases, thereby increasing the amount of heat radiation. As described above, the circulating fluid heated by the heating boiler flows into the radiator and flows through the radiator, so that radiant heat is generated from the front of the radiator, and convection heat is generated on the upper surface of the radiator to heat the room. .

In general, a natural convection type radiator such as a panel convector is installed under a window longer than the length of the window, and cold air entering the room through the window due to a temperature difference between the outdoor and the room. Is temporarily raised by convective heat generated from the upper surface of the radiator, thereby preventing cool air from flowing to the floor surface of the room, lowering the temperature near the floor surface, and increasing the temperature difference between the upper and lower parts of the room. Further, while the raised cool air descends, the cool air is warmed and convected, so that the room temperature can be raised without unevenness in the room temperature.

When the room temperature gradually rises due to heat radiation from the radiator, the thermosensitive body 1 in contact with the room air is gradually warmed by the slit of the operating member 19, and the thermo wax in the thermosensitive body 1 is heated. 4 also expands gradually. Then, as the thermo wax 4 expands gradually, the bellows member 3 in the temperature sensing element 1 is compressed, and the operating rod 5 is gradually pushed out. The distribution port 30 is gradually closed.

When the room temperature reaches the set temperature, as shown in FIG. 2, the gap between the horizontal portion of the blocking wall 31 in the connection pipe 28 and the tip end surface of the valve portion 25 has a heat quantity such that the room temperature rises.
There is no, but the cool air entering from the window is on the floor from the window
Generates convection heat enough to raise without descending
In a gap where the circulating fluid flows at a flow rate
The opening / closing valve 24 moves to a position where the circulating fluid flows at a flow rate of 20 to 30% of the maximum flow rate when fully opened in this embodiment .

Since such a gap is generated, the operating rod 5 and the opening / closing valve 24 are shortened, the mounting position of the valve portion 25 is shifted backward of the shaft portion, and The internal volume of the thermosensitive body 1 is reduced by providing a concave in the surface of the thermosensitive body 1 and then filled with the thermowax 4 to reduce the volume of the thermowax 4 or to reduce the expansion rate of the thermowax 4. The shrinkage of the bellows member 3 is reduced by changing it to a smaller one.

As described above , the blocking wall 31 in the connection pipe 28
The room temperature rises due to the gap between the horizontal part of
Although it does not have enough heat to cool,
How to raise the energy without lowering it from the window toward the floor
Circulating fluid at a flow rate that can generate
In this embodiment, the gap is a gap through which the circulating fluid flows at a flow rate of 20 to 30% of the maximum flow rate when fully opened. Convection heat can be generated so that cold air entering from the window rises without descending from the window toward the floor, thereby preventing the temperature near the floor from lowering.

In this state, if the room temperature continues to rise, the thermowax 4 expands further, the open / close valve 24 further lowers, the flow port 30 is completely closed, and the circulating fluid flows into the radiator. Is stopped so that the room temperature does not rise.

Although the flow rate when the room temperature reaches the set temperature is not enough to increase the room temperature , the flow rate from the window
Without letting in the cool air coming down from the window toward the floor
A flow that can generate enough convective heat to rise
Less than the amount, i.e. in this embodiment the flow rate at that time is less than 20-30% of the maximum flow rate, is placed below the window or the like
The convection heat generated by the radiator is too small to sufficiently raise the cold air that has entered through the window, causing a temperature difference between the top and bottom of the room, and conversely, the room temperature reaches the set temperature.
Flow rate is not enough to raise the room temperature
Of cold air coming from the window down from the window to the floor
Generate convection heat enough to raise without lowering
Is greater than the flow rate that can be achieved.
If the amount is more than 20 to 30% of the maximum flow rate, the radiant heat and convective heat generated from the radiator are too large, and the room temperature rises.

Next, another embodiment will be described. FIG. 3 shows a structure in which a secondary flow port 34 is formed in the blocking wall 31 in the connection pipe 28. This is provided at the end of the vertical portion below the blocking wall 31, and the outlet 30 is opened and closed at the tip end surface of the valve 25, whereas the secondary outlet 30 is opened and closed at the side of the valve 25. Is what is done.

The operation will be described. First, in the fully closed state, the flow port 30 is completely closed at the distal end face of the valve section 25, and the secondary flow port 30 is completely closed at the side face of the valve section 25. When the operation unit 19 on which the scale is displayed is turned to set a desired temperature, the holding member 7 moves in a direction away from the sliding member 12, so that the operating rod 5 retreats,
As a result, the open / close valve 24 is pushed up by the push-up spring 27, and the circulating fluid flows into the radiator from the communication port 30 through the gap between the blocking wall 31 and the valve body 25 and the secondary communication port 34.

When the room temperature gradually rises and the thermowax 4 in the temperature sensing element 1 also gradually expands, the bellows member 3 contracts and pushes the operating rod 5 to open / close the open / close valve 24 which is in contact with the operating rod 5. When the room temperature reaches the set temperature, the opening / closing valve 24 is pushed down to a position where the passage through which the circulating fluid passes becomes only the secondary circulation port 34 as shown in FIG.

The secondary flow port 34 is used to increase the room temperature.
Although it is not the amount of heat, the cold air entering from the window
From the floor to the floor
So that a flow rate that can generate heat flow flows.
In this embodiment, the open / close valve 24 rises and the blocking wall 31
The gap between the circulating fluid and the valve element 25 is maximized, and a flow rate of 20 to 30% of the maximum flow rate of the circulating fluid in the fully open state flowing through the gap and the secondary circulation port 34 is formed. It is a thing.

In this state, if the room temperature continues to rise, the thermowax 4 expands further, the opening / closing valve 24 further lowers, and the valve portion 25 also completely closes the secondary flow port 34 to release heat. The flow of the circulating fluid into the vessel is stopped so that the room temperature does not rise.

[0034] In natural convection type condenser-use temperature control valve of the present invention, as described above, even if the room temperature is reached a temperature set by operating the operation unit 19 not circulating fluid flow is zero, the upper room temperature
Although it is not enough to heat up, it invades through windows
Increase the cool air from the window to the floor without lowering it
The amount of circulating fluid that can generate convection heat
As it flows, that is, in this embodiment, the maximum flow rate is 20 to 3
Since 0% circulating fluid was allowed to flow, even if the room temperature reached the set temperature, the cool air from the window did not descend toward the floor ,
The convection heat generated by the radiator installed below the windows prevents the temperature of the floor from falling and the area near the floor to cool, and also prevents the temperature difference between the top and bottom of the room. Thus, it is possible to prevent a person in the room from feeling uncomfortable.
