Description

Warm water adjusting valve assembly

The present invention relates to a hot water temperature control valve mainly mounted on the hot water distribution pipe constituting the hot water distribution system, and more particularly, it is possible to appropriately adjust the temperature of the hot water for heating supplied to each room of the building where hot water for heating is supplied. The present invention relates to a hot water temperature control valve designed to contribute to energy saving (20% to 30%) while being more convenient to use by precisely controlling hot water temperature in response to each room condition.

In general, a hot water distribution system installed in a building heats water by a boiler to produce hot water, and the hot water is circulated through a hot water pipe embedded in each indoor floor of a house or other building, thereby heating the inside of the building. It is. At this time, the hot water distribution pipe constituting the hot water distribution system is to allow the user to selectively operate to circulate the hot water produced in the boiler to the area requiring heating or to block the hot water supply circulation for the area not requiring heating. Hot water temperature control valve is installed. That is, the hot water temperature control valve is installed in the hot water distribution pipe mainly installed in the apartment porch or kitchen, so that the hot water circulation supply amount can be adjusted by operating the hot water temperature control valve if necessary.

However, in the above hot water distribution system, since the lengths of the hot water pipes embedded in the floor and the distance between the boiler and the hot water pipes are different from each other, the temperature of the hot water is set to a specific temperature in the hot water distribution system. When the boiler is operated, there is a problem of insufficient control of the heating hot water corresponding to the same conditions as the area of each room of the building due to the uniformly set hot water temperature. In other words, in a building where the floor area is relatively large and the hot water pipe is long, the heating is not performed properly. In a room where the floor area is small and the hot water pipe is shortened, the temperature is too high. There is a problem of heating. For example, the temperature of the heated hot water may not be properly adjusted, which may result in some rooms being too cold and some rooms being heated too hot.

The temperature control valve employing such a shape memory spring is intended to increase energy efficiency by appropriately adjusting the heating temperature of each room of the building. In other words, if the temperature of the heating water rises too much, the heating efficiency is lowered due to excessive heating. Therefore, it is necessary to adjust the heating temperature to an appropriate range. For example, in the case of indoor heating, 20 ° C to 23 ° C can be regarded as the most appropriate heating temperature.

The present invention is to solve the above problems, an object of the present invention is to properly adjust the temperature of the hot water for heating supplied to each room of the building where the hot water for heating is supplied, its own structure is simple but reliable operation It is an object of the present invention to provide a hot water temperature control valve designed to expect a desirable result such as height.

When combined in the manner, it is possible to complete the assembly of the hot water temperature control valve of the present invention.

Referring to the process of installing the present invention having such a configuration in the hot water distribution pipe (2), the first screw portion 21 formed on the outlet side of the housing 20 to the bottom surface of the hot water distribution pipe (2) of the approximately straight pipe shape By screwing to the formed screw hole portion, the hot water temperature control valve of the present invention is installed in the hot water distribution pipe (2). At this time, the packing (P) interposed between the outer step 25 of the housing 20 and the lower surface of the hot water distribution pipe (2) is coupled to the hot water distribution pipe (2) by screwing the housing (20). While being pressurized, the sealing state between the hot water distribution pipe 2 and the coupling site of the present invention can be maintained. At the same time, the O-ring (OR) coupled to the outer circumferential surface of the temperature control valve body 40 is pressurized to the inner circumferential surface of the coupling hole formed in the upper surface portion of the hot water distribution pipe 2, so that the temperature control valve body 40 and the hot water distribution pipe ( The binding site of 2) may also be kept in a sealed state.

Next, the adjustment knob 42 is fitted to the outer circumferential surface of the upper end side of the temperature control valve body 40, and the spring washer 43 is fitted to the circumference of the bolt body 41 protruding to the upper end of the adjustment knob 42. Next, when the nut 44 is coupled to the bolt body 41, the upper end side of the temperature control valve body 40 in the present invention can be coupled to the upper surface of the hot water distribution pipe 2 without being separated, By finishing the tablet, the present invention can be installed in the hot water distribution pipe (2).

Then, by inserting the pipes embedded in each room of the building into the pipe connection portion 94 of the nipple 90 provided on the inlet side of the housing 20, and tighten the tightening nut body 80, the tightening ring body 96 is Since the pipe is pressurized, the pipe can be connected to the present invention.

According to the present invention having such a configuration, when holding the control knob protruding to the upper surface portion of the hot water distribution pipe (2) and rotates the temperature control valve body 40, the spiral groove 24 and the temperature control valve body 40 of the housing 20 When the temperature control valve body 40 is rotated up by the spiral protrusion 48 of its own, and the temperature control valve body 40 is rotated up, the shape memory spring 60 and the flow rate are caused by the elastic force of the finger holding means 70. Since the control cap 50 is raised together to open the inlet of the housing 20, hot water is supplied to the pipes embedded in each room of the building, thereby enabling heating of each room of the building. Of course, the water heat exchanged while heating the interior of the building is returned to the boiler by the circulation unit not shown, and is supplied again.

At this time, in the present invention, when the temperature of the hot water passing through the interior of the housing 20 and the temperature control valve body 40 is higher than the set temperature, the shape memory spring 60 is extended, the housing 20 inlet side By operating in close contact with the retaining ring 30, the hot water does not flow well toward the outlet, so that the heating temperature of the room can be automatically adjusted to an appropriate temperature.

On the other hand, when the temperature of the hot water passing through the temperature control valve body 40 and the housing 20 is lower than the set hot water temperature, the shape memory spring 60 is reduced, at the same time the finger holding means 70 flow rate by its elastic force Since the hot water passage is widened while pushing the adjusting cap 50 away from the retaining ring sieve 30 on the inlet side of the housing 20, the heating temperature of the room can be automatically adjusted to an appropriate temperature.

In addition, since the temperature control valve body 40, which is the main part of the present invention, has a tubular shape, the hot water outlet is opened and closed while rotating forward and backward in the housing 20 by a combination of the spiral groove 24 and the spiral protrusion 48. In addition, the operation structure is simple and the operation reliability can be expected to be higher.

In particular, the present invention due to the interlocking operation of the temperature control valve body 40 and the shape memory spring 60 and the support means 70 and the flow control cap 50 within the temperature range of the heating water 38 ℃ ~ 47 ℃ range By making it possible to adjust and use properly, the advantage is also the advantage in terms of heating efficiency and water conservation, etc. is the biggest feature.

In other words, the present invention employs only one shape memory spring 60 for 45 ° C. and at the same time, together with the temperature control valve body 40, the shape memory spring 60, the support means 70, and the flow control cap 50. By configuring the interlocking, as shown in Figure 4, by completely lowering the temperature control valve body 40 can adjust the heating water temperature to 38 ℃, as shown in Figure 5, the temperature control valve body 40 ) Can be raised to 47 ℃.

Then, by adjusting the temperature control valve body 40 to the intermediate position it is possible to precisely control the heating water temperature in the range of 38 ℃ to 47 ℃. For example, the heating water temperature can be raised to about 40 ° C. by slightly turning the temperature control valve body 40 upward while the heating water temperature is set at 38 ° C. In other words, when the temperature of the heating water is relatively low, the temperature can be slightly increased by slightly opening the temperature control valve body 40 while the temperature of the temperature control valve body 40 is felt when the heating water temperature is relatively high. By slightly lowering the temperature), the user can easily adjust the heating water temperature by operating the temperature control valve body 40 according to the room conditions, and this is the greatest feature of the present invention.

In addition, the present invention integrates district heating and individual heating without the need to separately manufacture district heating products and individual heating products (that is, products employing shape memory springs for district heating and shape memory springs for individual heating). Since it is designed as a single product, it is very preferable from the viewpoint of economy.

In addition, the present invention can be easily used to suit the temperature of the heating water within an appropriate range in accordance with the indoor conditions of the building, it is very preferable in terms of heating efficiency and energy saving (20% to 30%).

In addition, a plurality of outlet holes 46 are formed at radial intervals in a circumferential direction at a circumferential portion of the tubular temperature control valve body 40, which is a main part of the present invention, so that the water rising from the housing 20 is controlled by the temperature control valve. Since the inside of the sieve 40 is uniformly introduced into the hot water distribution pipe 2 through the plurality of outflow holes 46 in all directions, it is possible to contribute to more smooth and even heating. In other words, if only one inlet 46 is formed in the temperature control valve body 40, the water introduced with a constant propulsion force (constant pressure) into the interior of the housing 20 is the temperature control valve body 40 itself. The phenomenon that the vortex is generated will be aggravated while being hit, and thus, there is a possibility that the negative pressure is applied and the water is not distributed smoothly, and thus the hot water heating efficiency is lowered. By forming a plurality of outflow holes 46 to prevent such negative pressure and vortex phenomenon, thereby, water is smoothly distributed and it is possible to prevent the reduction of hot water heating efficiency. See FIG. 2.

In addition, in the present invention, the flow rate adjusting cap 50 has an end portion facing the retaining ring body 30 at the inlet side of the housing 20 in a convex shape at the center thereof, thereby allowing more precise control of the amount of hot water supplied to the pipe. This can also contribute to higher hot water heating efficiency.

In addition, since the retaining ring body 30, which is another main part, is coupled to the housing 20, the shape memory spring 60, the flow control cap 50, and the holding means 70 are supported so as not to be separated from each other. Assembly work can also be done more efficiently.

In addition, in the case of the present invention, the nipple 90 is provided separately from the housing 20, so that work such as pipe connection or disconnection is easier. That is, when the pipe is to be connected, loosen the tightening nut body 80 from the housing 20 to separate the nipple 90, insert the pipe connecting portion 94 of the nipple 90 into the pipe, and then nipple 90 ) Is inserted into the inlet side of the housing 20 and screwing the tightening nut body 80 back into the housing 20, the tightening of the pipe by the tightening ring 96 can be connected to the present invention, When removing the fastening nut body 80 only need to be released, it is possible to work more easily than when connecting or disconnecting the pipe in a state of fixing the hot water temperature control valve to the hot water distribution pipe (2).

At this time, as the fastening nut body 80 is screwed into the housing 20, the packing P interposed between the flange portion 92 of the nipple 90 and the retaining ring body 30 is pressurized, so that the pipe And the sealing state between the connection site of the present invention can be maintained firmly. That is, as the packing P is pressurized as the tightening nut body 80 is tightened, the coupling portion of the retaining ring body 30 and the housing 20 is sealed, and the nipple 90 and the retaining ring body 30 are sealed. ) Is also to seal the packing (P).

On the other hand, the tightening ring body 96 is to advance the inside of the housing 20 in the process of tightening the tightening nut body 80 and at the same time to reduce the diameter of the center around the cutout to press the fixed pipe, the tightening ring body 96 Tapered tightening guide surfaces 96a and 96b are provided at both ends of the one side of the tightening guide surface 96a to guide the tightening ring 96 smoothly along the inner circumferential surface of the housing 20, and on the other side. The tapered tightening guide surface 82a of the inwardly extending portion 82 provided at one end of the tightening guide surface 96b and the tightening nut body 80 reduces the diameter of the tightening ring 96 more smoothly in the inner diameter direction. As a result, the pressure fixing work of the pipe can be performed more smoothly.

In addition, since the pressing protrusion 97 formed on the inner circumferential surface of the tightening ring 96 is pressed with a concentrated force on the outer circumferential surface of the pipe, the coupling force of the pipe can be further increased.

In addition, the housing 20, which is a main part of the present invention, is formed on the outer circumferential surface of the flat surface 27 which is relatively concave than other portions, and the flat surface 27 forms the polygonal shape on the outer circumferential surface of the housing 20. The plural (20) is formed in the circumferential direction with respect to the center, and the first screw portion (21) of the housing (20) is screwed onto the lower surface of the hot water distribution pipe (2) for mounting or screwing. Since the tool can be rotated by coupling the tool to the polygonal shape formed by the plurality of flat surfaces 27 when released and separated, the operation of installing or separating the present invention in the hot water distribution pipe 2 can be made easier. In addition, the effect of reducing the material by the concave flat surface 27, as compared with forming a polygonal tool coupling portion (for example, outward tool coupling portion of the hexagonal cross-sectional shape) protruding further to the outer peripheral surface Can.

The present invention described above is not limited to the above-described embodiment and the accompanying drawings, and various permutations, modifications, and changes can be made without departing from the spirit of the present invention. It will be apparent to those who have it.
