Description

Water control valve for hot water distributor {A VALVE FOR USE IN HOT WATER DISTRIBUTION HEADER}

The present invention relates to an improvement of a water supply control valve installed in a hot water distributor of a hot water circulation system. In particular, the assembly and construction work of the valve can be made more easily, while providing excellent watertightness, and the manufacture and disassembly of the valve if necessary. The work also relates to a water supply control valve for a hot water distributor designed to be made simple.

In a hot water circulation system, such as a hot water heating system, a hot water dispenser is used to distribute and supply hot water produced in a boiler to a place where it is needed. A plurality of water supply control valves are installed to allow selection of supply and shutoff of hot water.

Fig. 1 shows one conventional valve configuration which has been installed and used in such a hot water dispenser, and this conventional valve has an internal passage by an operation knob 1 and a ball valve rotated by the operation knob 1. The valve body (3) having a screw coupling portion (2) formed on one side of the tubular body to be opened and closed, and the screw body side screw coupling portion on one side of the polygon flange (4) required for inserting a wrench when installing or disassembling the valve. Combination (8) forming (5) and the union nut side screw coupling portion (6) formed on the other side and the union nut side screw coupling portion (6) formed inside the hose connecting portion (7) of small diameter formed Are formed into separate bodies, and when the valve is installed, the assembly (8) is first assembled to the valve body (3) by coupling the screw coupling part (5) to the screw coupling part (2) of the valve body (3). The end of the connection target hose (H) to the hose connection portion 7 in the state After Kin via the clamping ring (9) on the outside thereof by tightening the union nut (10) screwed to the section 6 of the binder (8) is to fulfill the valve construction.

However, the conventional valve as described above separates the coupling body 8 having many processing points such as the polygonal flange portion 4, the screw coupling portion 5, 6 and the hose connecting portion 7 from the valve body 3 separately. Because of the large number of manufacturing process of the valve, the manufacturing cost is high, and the incidence of manufacturing defects is high. In addition, when the valve 8 is coupled to the valve body 3, the valve is required. Proper adhesiveness, such as epoxy resin, to the threaded portion 2 of the valve body 3, the screwed portion 5 of the joint 8 and the opposite side of the valve body of the polygonal flange 4 for maintaining watertightness. Since the valve body 3 and the coupling body 8 are assembled after the sealing material is applied, the assembly of the valve is more cumbersome and leakage occurs frequently due to the poor coating of the sealing material. To Dismantling was also very difficult, and there were problems such as the valve being damaged in a way that was not reusable.

Therefore, the present invention effectively solves the above-mentioned problems as described above, and thus, the production and assembly of the valve can be more easily performed, thereby minimizing the occurrence of defects in the manufacturing and construction of the valve and maintaining excellent watertightness. In order to provide a further improved water supply control valve for hot water distributors, the present invention has been devised.

The present invention for achieving the above object is the operation handle and the second screw coupling portion for screwing the first screw connection portion and the hose connection portion screwed in the union nut on one side of the valve body in which the inner passage is opened and closed by the operation handle Provided integrally formed, the water supply control valve for hot water distributors, characterized in that the second screw coupling portion of the valve body is installed by coupling the hose connecting portion via a seal.

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

Figure 2 of the accompanying drawings is a perspective view of the exploded state of the main portion of the valve according to the present invention, Figure 3 is a cross-sectional view of the combined use of the valve.

Here, reference numeral 20 denotes a valve body of the valve according to the present invention, and the valve body 20 is operated by the operation knob 21 and the ball valve 22 rotated by the operation knob 21 as in the conventional valve. The inner passage 23 has a tubular body that is opened and closed by.

According to the present invention, the polygonal flange portion 24 and the first and second screw coupling portions 25 and 26 are integrally formed on one side of the valve body 20, and the valve body 20 2, the screw coupling portion 26 is assembled by screwing the hose connecting portion 27 formed separately from the valve body 20 via the seal 28.

As described above, the end of the hot water circulation hose (H) of the associated hot water circulation system is inserted into and installed on the outer side of the hose connecting portion 27 assembled to the valve body 20, and interposed therebetween with a tightening ring 29. When the union nut 30 is screwed into the first threaded portion 25 of the valve body 20, the tightening ring is formed by the action of the inclined surface 31 formed inside the union nut 30. 29) is clamped toward the hose H so that the hose H is firmly pressed against the hose connection 27 of the valve.

According to this configuration, the valve of the present invention is formed by separating the hose from the valve body 20, the hose connecting portion 27 is much smaller than the combination 8 of the conventional valve described above to form the second of the valve body 20 Since it is possible to achieve the desired valve configuration by attaching to the screw coupling portion 26, the manufacture and assembly of such a valve can be made much simpler than before, and the same epoxy resin as before in the valve construction. The assembly and watertightness of the valve is ensured because almost perfect water tightness is ensured by simply assembling the hose connecting portion 27 to the valve body 20 via the seal 28 without applying the sealing material between the valve assemblies. Excellent and, if necessary, to disassemble the valve from the installation location, even in the multiple flange portion 24 formed integrally provided in the valve body 20 By inserting values can easily operate to rotate the entire valve and provides significant advantages in that to occur facilitate easy hardly result in disassembly also damage to the valves of the valve.

Therefore, the present invention further improves the manufacturing, assemblability, and watertightness of the water supply control valve for hot water distributors by the configuration and operation as described above, and the dismantling operation of the installed valve is also easily performed if necessary without damaging the valve. It is a new useful effect that makes it possible to produce.
