Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to a valve with a cable duct.

0002

[Conventional technology]

Generally, when supplying water from a river, etc., one or more water pipes are connected. Install flow control valves (butterfly valves), flow cutoff valves, pumps, etc. at designated locations in the water pipes. It is carried out separately. And to operate and control the flow control valve, flow cutoff valve, pump, etc. A power supply is required, and communication equipment and control equipment are essential for these management facilities. be.

0003

[Problem that the idea aims to solve]

By the way, it is economically desirable to install water pipes at the shortest geographical distance possible. Delicious. However, in special areas such as deep in the mountains, power sources are not necessarily nearby. Furthermore, communication cables and control cables do not necessarily run near the water pipes. At the same time, there are geographical restrictions when constructing water conduits together. There was a problem.

0004 In addition, water conduit facilities, power and communication cables, control cables, etc. are constructed separately. Therefore, there was a problem in that the cost increased economically.

[0005] This idea was made in view of the above problems and is subject to geographical restrictions. A highly economical cable that allows water pipes to be installed over the shortest distance without any problems. An object of the present invention is to provide a valve with a duct.

[0006]

[Means to solve the problem] This idea solves the above problem by storing various cables in the valve box and bypassing them. It is configured with a cable duct.

[0007]

[Effect]

According to the cable duct-equipped valve according to this invention, the cable duct is provided in the valve box. Therefore, connect the power cable, communication cable, and control cable to the cable duct in advance. If you store and route various cables such as control valves and ports, It can be operated by connecting to the pump and management equipment.

【Example】

An embodiment of this invention will be described based on the drawings. The drawings are examples of this invention. Figure 1 is a front view showing the configuration of the valve with cable duct, and Figure 2 is its side view. 3 is a detailed diagram showing the main part (part P) of FIG. 2. FIG.

[0009] 1 is a cylindrical valve box that has a communication hole 1a through which fluid flows and is connected to a water pipe. Ru. Reference numeral 2 denotes a disc-shaped valve body that opens and closes the communication hole 1a. 2a is a reinforcing material for the valve body 2 , 2b (Fig. 2) is a valve seat made of a material such as synthetic rubber. 3 is a valve shaft that rotates the valve body 2 in the opening and closing directions. 4 is a bearing for the valve shaft 3. 5 is a parallel pin for connecting the valve shaft 3 and the valve body 2.

0010 6 is an opening/closing machine for opening and closing the valve body 3. The internal structure of this switch 6 is shown in the diagram. However, a known method is adopted, for example, a bevel gear on the output shaft of the switch 6. A bevel gear that meshes with the bevel gear is provided at the tip of the intermediate shaft. It is constructed by meshing a spur gear provided at the base end of the intermediate shaft with a spur gear provided on the valve shaft 3. Ru.

[0011] 7 is a handle that rotates the output shaft of the opening/closing machine 6. Reference numeral 8 denotes a leg section provided at the bottom of the valve box 1. 9 is the valve box valve seat (Figure 2).

0012 10 is a cable duct which is the main part of this invention, as shown in Figs. 2 and 3. It is provided at the bottom of the valve box 1. As shown in FIG. 3, this cable duct 10 includes a power cable, a communication cable, Conduits 10a, 10a that lead various cables B such as control cables from the outside, and cables A hollow storage case 10b is provided at the bottom of the valve box 1. has been done. A cable supporting cable B is located in the center of the storage case 10b. A holder 10c is provided. The cable receiver 10c has a through hole through which the cable B passes. A hole 10d is bored.

[0013] According to the valve A with a cable duct according to this invention, the cable duct is attached to the valve box 1. Since the cable duct 10 is provided, the power cable and communication cable are connected to the cable duct 10 in advance. If you store and route various cables B such as cables and control cables, you can The cable B can be connected to control valves, pumps, and management equipment for operation. Therefore, those various cables do not pass nearby, and the cable duct 10 It is sufficient to use cable B housed in the This allows water pipes to be connected in the shortest possible distance.

[0014] This invention is not limited to the above-mentioned embodiments, but is also applicable to utility model registration requests. Changes in species are possible within the scope of the technical matters described in the scope. example For example, although a horizontal butterfly valve is used in this example, it is also suitable for a vertical butterfly valve. may be used. Further, the cable duct 10 may be provided on the side surface of the valve box 1.

[0015]

[Effect of the idea]

The valve with cable duct according to this invention exhibits the following excellent effects. do.

[0016] Since a cable duct is provided in the valve box, connect the power cable to the cable duct in advance. If you store and route various cables such as cables, communication cables, and control cables, These cables can be connected to control valves, pumps, and management equipment for operation. Ru. Therefore, the installation location of the water pipes is not subject to geographical restrictions, and the water pipes can be installed at the shortest possible distance. Can be connected by distance.

[0017] During construction, water transmission pipe facilities, power supply and communication cables, control cables, etc. are separated. There is no need for additional construction, making it highly economical.

[0018] Even if the valve is closed due to control of the flow control valve or flow cutoff valve, various cables are The valve itself remains closed without being obstructed by various cables. can be done.
