DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluid distribution / supply means for dividing and distributing a fluid.

[0002]

2. Description of the Related Art When a liquid is supplied to a plurality of parallel down flow paths, water is usually sprayed down each of the down flow paths using a header pipe provided with a perforated nozzle. Although the flow rate of each nozzle is not constant, it is a simple watering method. If there is a request to make the flow rates uniform, it is necessary to attach a valve to each nozzle and adjust the flow rate for each valve.

More specifically, in the case of the snowmelt sheet (S) for a tiled roof shown in FIG. 1, four flow-down paths (F) are provided in a range of about 410 mm width corresponding to one row of the roof. . Conventionally, a header pipe (P) provided with a total of four valves (not shown) has been attached to these flow paths.
The header pipes are arranged in multiple stages at intervals of 4 to 6 meters along the roof surface, and hot water is discharged from each pipe to melt snow. Vertical 1 constructed by the applicant
On a 2-meter, 20-meter-wide roof tile roof, 320 valves were used in two rows of header pipes attached at intervals of 6 meters above and below.

In the conventional water supply method, a large number of valves must be used. The installation of a large number of valves is a very tedious and time-consuming task and has the disadvantage of being expensive.

When the above-mentioned equipment was actually operated, fine silt particles passing through the filter adhered and accumulated on the valve seat, and the flow rate of the valve fluctuated with the passage of time, and some of them were completely blocked. . There are still issues in terms of maintenance.

[0006]

In order to solve the above-mentioned problems associated with the use of a valve, an accommodation space for receiving a fluid is formed by an upper weir in the form of a flat plate, and a fluid flowing out of an orifice of the upper weir is formed into a mountain shape. It is configured so that the fluid flowing out of each of these accumulation areas is received by the lower weir and discharged from a plurality of openings, and the fluid is managed in a planar manner. I decided that.

[0007]

The upper weir blocks the fluid supplied through the valve or the fluid flowing down from above. The fluid received by the upper weir does not flow out immediately, but is stored in an appropriate amount. When the upper weir blocks the fluid supplied through the valve and the fluid flowing down from above, both fluids are stirred and mixed. Fluid collects in the middle of the storage area and flows out of the orifice in an orderly manner. The fluid passing through the outflow orifice collides with the diversion weir and the flow is divided into right and left. If the center of the diversion weir is at the center of the flow of the fluid, the flow is divided almost equally to the left and right, and if it is located to one side, the divided flow rate changes in accordance with the ratio.

[0008] The fast flow along the diversion weir is slowed down in the area on both sides of the diversion weir and the movement is buffered. Fluid accumulates in this buffer zone and exits the buffer zone and is supplied on average to the lower weir located below. The lower weir is provided with a plurality of passages, and the fluid flows out at a flow rate unique to each passage.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, specific examples of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 shows an example of the fluid distribution / supply means and its usage. For convenience of explanation, the fluid distribution and supply means is used in the snow melting sheet. As described at the beginning, the snow-melting sheet S constitutes a planar planar heating element having four flow-down paths F. Fluid used as a heat source is, for example, boiler hot water or groundwater,
Snowmelt itself is also used as a heat carrier. Note that the illustrated sheet may be referred to as a heat collecting sheet for collecting hot water. The fluid distribution and supply means 1 is adhesively fixed on the snow melting sheet S adjacent to the header pipe P.

In the example shown in the figure, the fluid distribution / supply means 1 is composed of a plate-like structure made of synthetic resin, rubber, ceramic, cement, or the like. A weir 3 is placed, and a lower weir 4 is installed on the downstream side. The fluid is supplied through a valve V installed in the header pipe P. The valve V and the snow melting sheet S are in a positional relationship such that fluid can be supplied to two snow melting sheets on both sides of the valve. The fluid sent from the valve through the flexible tube C is divided into four parts while flowing down through the fluid distribution and supply means 1. Therefore, one plate serving as the fluid distribution and supply means 1 plays the role of four valves. According to this arrangement example,
In the case of the above-mentioned tile rod roof, the total number of valves used is 40, which is only one-eighth that of the conventional one of the same size.

The fluid distribution and supply means 1 receives a fluid,
An intermediate weir is provided with an upper weir 2 forming a fluid storage area for collecting fluid. The upper weir 2 has a fluid outflow orifice 5. The outflow orifice 5 is provided with a mountain-shaped diversion weir 3 that divides the outflowing fluid. Fluid traveling along the diversion weir flows into the buffer zones 6 located on both sides of the diversion weir. The buffer zone serves to store the moving fluid and buffer the movement.

A lower weir 4 is disposed at a position for receiving the fluid flowing out of the buffer area. The shape of the lower weir 4 is shown in FIG.
2 and 4 are common, and both have a mountain shape.
The lower weir 4 shown in FIGS. 3 and 5 is in the form of a straight weir. The number and arrangement of these lower weir passages is a matter of choice.

FIG. 4 shows the structure and arrangement of the fluid distribution and supply means 1 arranged at an intermediate position of the snow melting sheet. 1 is basically the same as that of FIG. 1, but the upper part of the storage area is open, and the fluid flowing down along the sheet flows into the storage area and is blocked by the upper weir 2. At the same time, the fluid is supplied from the header pipe P via the valve V, and the fluid flowing from above the seat and the fluid from the valve are mixed and stirred.

The fluid distribution and supply means 1 shown in FIG. 4 is made of a sheet-like base material, unlike the one shown in FIG. This sheet-shaped substrate has water absorption,
For example, when fabric is used, the fluid tends to spread well on the surface and accumulate laterally.

[0015]

According to the above construction, the operation which was originally supplied individually using the valve can be replaced by one article, the cost can be reduced, and the construction can be easily performed. In addition, since the structure is exposed to the outside, inspection and repair can be easily performed.
