Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a header device for floor heating that completely eliminates the inefficiency of the flow setting operation at the construction site and at the same time rationalizes the assembly operation of the header (distribution fitting).
[0002]
[Prior art]
In floor heating systems and snow melting systems using hot water, metal headers are used to supply hot water to a plurality of installed distribution pipes, and a plurality of headers are provided on the headers. An opening / closing valve and a flow meter are assembled to each of the branch ports. The on-off valve is used for temporarily shutting off hot water for venting the pipe, repairing the pipe, etc., and the flowmeter is used for setting the flow rate for each pipe.
[0003]
[Problems to be solved by the invention]
The on-off valves and flowmeters are currently assembled to the header one by one at the construction site, and the assembly work at the site is very cumbersome when the quantity increases, and there is a risk that it will be assembled by mistake. is there. In addition, since the flow rate of each pipeline is set one by one using a flow meter, it is inevitable that work takes a lot of manpower and time, and it is extremely inefficient and a solution was desired. .
[0004]
The present invention solves such a problem, and an object of the present invention is to use a constant flow valve in which the flow rate to each pipeline is set in advance instead of a conventional flow meter, and to use this constant flow valve together with an on-off valve. Unitized by assembling in the header, saving the work of assembling the valve and setting the flow rate at the construction site so that anyone can easily install the floor heating system , and noise generated during the distribution of the heating medium An object of the present invention is to provide an improved floor heating header device that reduces noise and noise while improving durability .
[0005]
[Means for Solving the Problems]
In order to achieve the above object, a header device for floor heating, which is a feature of the present invention, includes a pair of headers used on a high temperature side and a low temperature side of a heating medium, and each header has a plurality of branch ports. provided, close valve capable of connecting the flow pipe of the heating medium in each branch port of the high temperature side header of the both headers, and each branch port portion of the low-temperature side header to each conduit Each of the constant flow valves having a preset flow rate is connected, and each of the constant flow valves is connected to an open / close valve that can connect a distribution pipe for the heating medium.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings. Reference numerals 1 and 2 denote headers. The pair of headers 1 and 2 are set with a step on a frame 3 installed between walls, and the lower header 1 is a high-temperature side (supply side) header of a heating medium. The upper header 2 is used as a low temperature side (return side) header of the heating medium. Incidentally, the both headers 1 and 2 steel, stainless steel, which is made of metal such as copper is formed in a tubular shape, each plurality of the branch port portion 1a, 2a are provided.
[0007]
On- off valves 4 are screwed into the branch ports 1a of the high temperature side header 1, and constant flow valves 5 with predetermined flow rates to the respective pipes described later are screwed into the branch ports 2a of the low temperature side header 2. And the open / close valve 6 is connected to each of the constant flow valves 5 by screwing. Off valve 4,6 are shared also joint distribution pipe p constituting the conduit between the high temperature side header 1 and the low temperature-side header 2, between 1 and 2 the two header by the connection of the flow-class pipe p Consists of a plurality of pipes.
[0008]
The constant flow valve 5 is provided with an orifice plate 51 in which a flow hole 51a is formed, and has a known structure in which the flow rate can be set in advance by the diameter of the flow hole 51a, and is screwed into the branch port 1a. A male screw portion 52 and a female screw portion 53 that are screwed with the male screw portion 61 of the on-off valve 6 are provided. On the other hand, the on-off valves 4 and 6 have a known structure that can open and close the flow path by the rotation of the valve body, and are provided with joint portions 42 and 62 for connecting the flow pipe p, respectively. On the side, a male screw portion 41 that is screwed into the branch port portion 1a is provided.
[0009]
The joint portions 42, 62 are male threaded portions 42a, 62a, inner core portions 42b, 62b projecting from the male threaded portions 42a, 62a, split rings 42c, 62c, and fastening bags, as in the case of ordinary plastic pipe joints. 42d nut consists 62d, a distribution pipe p fitted to the inner core portion 52 b (62b), and sandwiched between the pre-distribution pipe p is fitted into the split ring 4 2c (62d) The distribution pipe p can be connected by a tightening operation with a cap nut 42d (62d) screwed into the male screw portion 42a (62a). The distribution pipe p is made of thermoplastic resin (for example, low density cross-linked polyethylene), steel, copper or the like.
[0010]
According to the above configuration, the on / off valve 4 is assembled in the high temperature side header 1 and the constant flow valve 5 and the on / off valve 6 are assembled in the low temperature side header 2 in advance. in each of the distribution pipe p being constructed using joint portion 42, 62 of the opening and closing valves 4 and 6 only is connected between the both headers 1 and 2, the flow rate for each line is set Easy to install floor heating. In the figure, 7 is an air relief valve mounted on the cold side F Dda 2 of the heating medium.
[0011]
【The invention's effect】
The present invention is as described above, and since there is no need to set the flow rate for each pipeline at the construction site, it is possible to achieve a significant reduction in manpower and time, and there is an advantage that the floor heating system can be efficiently constructed. . In addition, noise and noise generated during the distribution of heating media can be reduced and durability can be improved.
