Description

Connection structure of hot water distributer and valve}

The present invention relates to a hot water distributor, and more particularly, by insert molding the insert into the distribution port of the hot water distributor for distributing the heated hot water in the boiler to be sealed with the valve, which may occur through the gap that can be caused by the difference in thermal expansion The present invention relates to a hot water distributor valve connection structure that prevents leakage.

A hot water distributor is a hot water circulation heating system that generates hot water by heating water with a boiler and circulates the hot water through a pipe embedded in the floor of a room or living room, such as a house, to perform heating. It means that the user can select and operate the hot water to circulate the hot water to the heating zone or to cut off the hot water supply to the zone that does not need the heating.

As shown in FIG. 1, the hot water distributor collects hot water heated in a boiler and supplies a distribution capillary 10 to each distribution port 20, and supplies hot water generated in the boiler to the distribution capillary 10. It consists of 12.

In particular, the distribution port 20 has a thread 22 is formed on the outer peripheral surface, the thread 22 is a valve (not shown) to enable the user to arbitrarily supply the hot water of the distribution capillary 10 to the area requiring heating If the valve is installed on the thread 22 formed on the outer circumferential surface of the distribution port 20, the thermal expansion difference between the distribution port 20 formed of synthetic resin and the valve formed of metal such as bronze or brass Due to this, a leak was generated. For this purpose, a method of forming a hot water dispenser using bronze or brass has been proposed, but there is a problem in that a manufacturing cost of the hot water dispenser is increased.

In addition, in order to solve the above-mentioned water leakage problem, a packing method or a taping treatment is disclosed in the distribution port 20, but there is a problem in that it takes a lot of work time and is not easy to work.

The present invention has been made to solve the above problems, by insert molding the insert into the distribution port of the hot water distributor for distributing the heated hot water in the boiler to be sealed with the valve can occur through the gap that can be caused by the difference in thermal expansion It is an object of the present invention to provide a hot water distributor valve connection structure that prevents a leak.

The present invention devised to achieve the above object is as follows. The present invention is a hot water dispenser for distributing hot water generated from the boiler to the distribution capillary formed of synthetic resin to the area requiring heating through the distribution capillary, the pipe part for supplying and draining hot water to the distribution capillary injection integrally with the distribution capillary Molded inserts are provided with threaded inserts inside the pipes to be connected to the valves, and stainless steel compression rings are installed on the insert outer circumference to suppress gaps between the inserts and pipes by hot water. It is characterized in that it is possible to prevent the leakage phenomenon that can occur in between.

Here, the outer circumferential surface of the tube portion is formed with a projection protruding in the side, the pressing ring is formed in the pressing ring corresponding to the locking projection, the locking projection is fixed through the locking hole through the locking hole.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.

Figure 2 is a perspective view of the hot water distributor according to the present invention, Figure 3 is an exploded perspective view of the hot water distributor valve connection structure according to the present invention, Figure 4 is a side cross-sectional view of the hot water distributor valve connection structure according to the present invention.

The hot water distributor of the present invention, as shown in Figure 2, the distribution capillary 10 for distributing hot water supplied from the boiler (not shown) to be supplied to the area requiring heating, and the hot water to the distribution capillary (10) It is made of a connection structure (100,200) for supplying and supplying hot water from the distribution capillary 10 to the area requiring heating.

Since the distribution capillary 10 has the same material and shape as the related art, a detailed description thereof will be omitted.

The connection structures 100 and 200 are configured to supply and distribute hot water, and thus the functions of the connection structures 100 and 200 will be described by using the connection structure 100 for distributing hot water as an example.

The connection structure 100 is largely comprised of a pipe part 110, a compression ring 120, and an insert 130.

First, the pipe part 110 is injection molded integrally with the distribution capillary 100 and the insert 130 is inserted molded therein. In addition, the upper portion of the pipe portion 110 is formed with a coupling portion 114 in which the compression ring 120 is installed on the outer circumferential surface, the outer ring of the coupling portion 114 to the side so that the pressing ring 120 can be fixed A protruding locking protrusion 112 is formed and recessed in a stepped shape along the circumference at the upper end thereof. On the other hand, the inside of the pipe part 110 is protruded along the circumference inward to form a step 116 for supporting the insert 130 described later from the bottom.

Insert 130 is formed of a bronze or brass material is inserted into the inside of the tube 110, the lower end is located on the step 116 formed in the tube 110, the inner circumferential surface of the thread 132 is formed This thread 132 is screwed into the valve (not shown). Therefore, the insert 130 is formed of the same material as the valve so that a gap due to heat does not occur.

Finally, the pressing ring 120 is preferably made of stainless steel is installed outside the coupling portion 114 of the pipe portion 110, the locking hole 122 to correspond to the locking protrusion 112 described above. Is formed so that the locking protrusion 112 penetrates the locking hole 122 and is fixed to the outer circumferential surface of the coupling part 114, and a bent part 124 having an upper end bent inward is formed at the upper end of the coupling part 114. It is located in the groove.

Since the pressing ring 120 is strongly pressed on the outer peripheral surface of the coupling part 114, the insert 130 can be fixed to the inside of the pipe part 110, and the insert 130 is caused by the temperature of the insert 130 by hot water. Since the deformation of the coupling part 114 is suppressed, the pipe part 110 may be prevented from being damaged, thereby preventing leakage into the gap between the pipe part 110 and the insert 130.

The present invention is not limited to the above-described embodiment and can be implemented in various modifications within the range allowed by the technical idea of the present invention.

According to the present invention constituted as described above, the insert is molded into the distribution port of the hot water distributor for distributing the heated hot water in the boiler formed of synthetic resin and combined with the valve, and the difference in thermal expansion between the valve and the distribution port is compressed. It can prevent the water leakage which can be caused by the gap.
