JPH10150866A - Improved stop valve - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide improved stop valve structure with which sun-heated warm water can be let flow into an underdrain duct as it is, the level of reserved water in a geologic stratum is automatically adjusted and growing property, operability and power saving can be improved by eliminating a stop vane. SOLUTION: There is no stop vane. In this case, this improved stop cock is the opening pipe of a water supply port pipe 9 connecting and sticking an opening pipe for a prescribed length through adhesive paste to another terminal with the insert bonding part of a perpendicular curved pipe 3 as a rotary shaft at both the terminals of insert type bonding part of an underdrain duct 2, the head part is made into the same opening pipe as a paddy field surface water reserving horizontal plane 13 and concerning a water supply/drain cock, the improved water cock is installed while installing a concrete break destruction protecting frame 18 on the outside water channel and drain channel side of paddy field levee 19. When stopping the up and down changes of water supply port pipe 9 and water drain port pipe, while utilizing the outer diameter of insert part of a cover pipe 5 and a gap between the through holes of protecting frame 18, the rotary shaft is stopped with a thick rubber ring 21 as a compression stopper.

Description

DETAILED DESCRIPTION OF THE INVENTION

As shown in the drawing, the present invention has 27 improved water stopcocks without water stop vents. Of 1
1 open pipe is connected and bonded by glue glue. 9 open water pipes are 11 open pipes, 27 improved water stopcocks without 27 water stop vents of the present invention and 2 drain pipes at the other end of culvert pipe have the same structure. The mouth was an 11-opened pipe, and the head was an 11-opened pipe, which was the same as the 13 paddy surface water storage horizontal plane. (1) With the improved water stopcock, both are required to be connected to each other before being combined with the eight rotation shafts. Temporarily insert it at the end of the pipe, insert the 26 water leakage prevention rubber ring into the slightly longer pipe of the 6-rotation shaft stop ring pipe, and glue it to the predetermined position with adhesive glue.
1 improved water stopcock with 9 water supply pipes and 10 drainage pipes, both of which are made upright and can be changed horizontally.
9 Water-supply faucet and 30 drainage faucet are installed in each of the 18 protection frames made of concrete shown in the drawing to prevent damage in the waterway side of 9 paddy fields.
If the 11-opening pipe is submerged in the water drawn from the 16 canals, the flowing water will flow from the 11-opening pipe, and will flow into the 2 culvert pipes, and part of the water will flow from the 28 discharge holes of the 14 cultivated stratum into the stratum and the plant roots. And the excess is distributed through two underdrain pipes and
0 Through the siphon section of the drainage pipe, the expected position of the 13 cultivated soil reservoirs, outside is discharged from the 11 open pipes of the 10 drainage pipes to the 17 drainage channels, and the 23 cultivated soils are changed by changing the upright side of the 10 drainage pipes. The water storage level is freely discharged from the 10 drain pipes, the formation seepage water enters through the discharge holes of the 2 culvert pipes and is discharged sequentially, the upper side of the 2 culvert pipes is hollow, and the lower side flows out of the 10 drain pipes. The temperature of the outside air goes to the low temperature part because of the characteristic that goes to the low temperature part. It circulates in the direction of 9 water supply pipes from 10 drain pipes, and is exchanged with the formation cold air to some extent, so that the formation cold air in 2 culvert pipes can be discharged. Is possible if a special blower is maintained and installed. The plumbing tap shown in the drawing is a concrete breakage 18
The protective frame was installed on the outside of the 19 paddy field outside the 16 waterways and 17 drainage channels, and the improved water stopcock of the present invention was installed. By using the outer diameter of the insertion portion and the space between the through-holes of the 18 protective frame, a 21-thick rubber ring is used as a compression stopper to stop the rotation shaft.

[Industrial application] Simple stopcock structure without 27 stopcocks of 1 improved stopcock, used for 4 stopcocks for water replenishment of 2 underdrain plumbing equipment of cultivated soil layer.

2. Description of the Related Art A conventional four stopcock is constituted by an open / closed 27 water stop vent, and at the time of passing, becomes high pressure running water to some extent. Pass, 22
The sunshine temperature decreases. The amount of water supply and drainage was difficult to confirm, and both operation and labor were required separately for water supply and drainage. 23 The water level in the stratum could not be automatically adjusted.

[Effect] On the 22nd day, hot water can flow into the two underdrain pipes as it is, exchanged with the formation low temperature, the low temperature is discharged, and the temperature dissipation is radiated to the formation surface. The operation of the replenishment drainage is easy due to the change of the raising and lowering of the 11-opening pipe, and even if the replenishment is excessive, the assumed 23 reservoir levels are automatically released and the sense of security is great. It can be assembled with off-the-shelf tubing and can be constructed at low cost without the need for technology.

[Example] The distribution water passed through 4 stopcocks, and there was no decrease in irradiated hot water on the 22nd, as expected. As the 22nd irradiated water passed through the culvert pipe, the water discharge temperature from the 10 drainage pipes was initially cold. However, the temperature rose in the beginning. Initially it took a long time.

[Effect of the Invention] In the era of transplanting seedlings that have been germinated in a greenhouse in a greenhouse in recent years, even in early spring, the outside air and night cooling are severe, and the state of raising seedlings raised on greenhouses is prolonged. Naturally, if the cultivation of 14 cultivated strata can be made hotbed by passing through two culverts with sunshine hot water, it is natural that the seedlings can be quickly planted and planted, and the growth effect will affect the harvest. The characteristic of the temperature is that it does not fall even if it rises and diverges. 2 It is the method of circulating the sunshine temperature in the culvert pipe for 22 days and raising the temperature of the cultivated stratum by at least 14 by using the culvert. The drain cock is a modified tap with no water stop vent. The tap is passed straight through the water supply and drain port without injecting the illuminated water on the 22nd, and exchanged with the formation cold air in the two culverts. Since 30 drain plugs are also released without pressure water because there is no 27 stop water vent, there is also an effect that the sedimentation rate of sediment is small in the culvert pipe, and there is no water pressure in the culvert pipe and the water supply and drainage with normal running water power I can do it. The inflow and outflow from the mouth of the pipe can be witnessed, and the increase and decrease can be freely adjusted by raising and lowering the water supply and drainage pipes. 10 drainage pipes are required from the 2 culvert pipes buried in the layer to 13 rice field storage planes, and several 10 outlets were required with 10 siphon drainage pipes, but only one outlet is needed by raising and lowering 11 open pipes. .
