Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a synthetic resin sluice used for adjusting the water level of irrigation water, groundwater, etc.

[Conventional technology]

Conventionally, this type of synthetic resin water lock has an operating rod mounted approximately in the center of the water lock body, with a partition wall having a water discharge port tilted between a water inlet and a drain port formed on both sides of the lower part of the water lock body. Generally used is a valve in which a valve is provided at the lower part thereof with the same slope as the partition wall and is removably abutted on the periphery of the water outlet so that it can be opened and closed.

[Problem that the invention attempts to solve]

This type of water lock is used to adjust the water level of irrigation water, groundwater, etc., and since this water level adjustment involves opening and closing of a valve installed at the bottom of the water lock body, the valve naturally requires watertightness. .

However, molded products made of synthetic resin suffer from distortion during molding, and the operation tube is long and bendable, at around 2 m, and is regulated by an upper cap so that it is located in the center of the lock body. Because of this, it was a very difficult task to fit the valve located at the bottom of the valve in a watertight manner to the periphery of the water outlet.

[Means to solve the problem]

This device was devised to solve the above-mentioned drawbacks of the conventional products, and a partition wall having a water outlet is tilted between the water inlet and drain port formed on both sides of the lower part of the water lock body. In a synthetic resin water lock in which a valve provided at the lower part thereof with the same slope as the partition wall is detachably attached to the periphery of the water outlet and can be opened and closed by the upper and lower parts of the operating pipe installed approximately in the center. A small diameter pipe is inserted into the upper end of the large diameter pipe that is erected on the valve so that a predetermined distance is formed between the pipe walls, and a stopper is inserted into the long hole formed in the superposed pipe. The problem was solved by using an operating tube that was inserted through the tube and connected so that it could swing back and forth and left and right. [Example] Hereinafter, an example of this invention shown in the drawings will be explained. Fig. 1 is a partially cutaway sectional view showing an example of a synthetic resin water lock of this invention, and 1 in the figure is a comparatively The main body of the water lock is made of a synthetic resin pipe with a large diameter. 2 and 3 are a water inlet and a drain port formed on both sides of the lower part of the main body 1 of the water lock, and 4 is a water inlet to block the water inlet 2 and the drain port 3. 6 is a water outlet formed approximately at the center of the bulkhead 5, which is tilted to the top, and 6 is an operating pipe installed approximately at the center of the lock body 1, which is a large-diameter short tube erected on the valve, which will be described later. A small-diameter long tube 62 is fitted into the upper end of the tube 61 so that a predetermined gap 8 is formed between the tube walls, and the superposed tube 6
1 and 62 are connected so as to be able to swing with a stopper 9, and 7 is a valve attached to the lower end of the operating tube 6, which has the same slope as the partition wall 5. It is formed so that it can be detachably abutted on the periphery of the water outlet 4 by means of the upper and lower portions of the operation tube 6 and can be opened and closed.

Note that the hole 10 of the large-diameter short pipe 61 through which the stopper 9 is inserted
The valve 7 is formed in the shape of a long hole so that it can swing back and forth and left and right.

[Effect of idea]

As is clear from the above, this invention is based on the operating tube 6.
A small diameter long pipe 62 is fitted into the upper end of the large diameter short pipe 61 that is erected on the valve 7 so that a predetermined gap 8 is formed between the pipe walls, and the superposed pipes 61 and 62
Since the structure is connected so that it can be swung by a stopper 9, the installation position of the operating tube 6 may become incorrect, or the operating tube 6 itself may be bent, as shown in Fig. 4. Although distortion occurs during molding, the position is corrected by swinging the valve 7 portion as shown in Figure 3, and the valve 7 is evenly attached to the periphery of the water outlet 4, achieving the desired watertight effect. is played.

Claims (1)

[Scope of utility model registration request] A partition wall with a water outlet is tilted between the water inlet and drain port formed on both sides of the lower part of the water lock body, and the same slope as the partition wall is made at the lower part by the upper and lower part of the operation pipe attached to the approximate center of the water lock body. In a synthetic resin water lock in which an attached valve is removably attached to the periphery of the water outlet and can be opened and closed, a valve is attached between the pipe walls at the upper end of the large diameter pipe 61 erected on the valve 7. A small-diameter tube 62 is inserted so that a predetermined interval 8 is formed, and a stopper 9 is inserted into a long hole 10 formed in the overlapping tubes 61 and 62, so that the tube can be swung back and forth and left and right. A synthetic resin water lock characterized by using an operating pipe connected in a manner similar to the above.
