Description

Contant water level control valve system using by electric operation ball valve}

The present invention relates to a water level valve system using an electric ball valve, and more particularly, to irrigation water such as water or liquid fertilizer along a long branch pipe to a watering device for spraying water or liquid fertilizer to a large farming complex or an outdoor golf course. When supplying through the control, by operating the water level valve device by controlling the opening and closing of the electric ball valve provided in the water level valve device from a remote location, it is to enable the irrigation water such as water or liquid ratio to be supplied to the watering device.

Conventionally, large-scale farming complexes or outdoor golf courses, etc. are using a separate equipment to spray fertilizers or pesticides. For example, in the case of a golf course, a tank is loaded in a loading box of a mobile vehicle, and each fertilizer or pesticide is sprayed using a spray device coupled with the tank while moving each hole. Therefore, in golf courses, etc., fertilization or reagents are applied according to the development and management of the grass or the natural environment of the surroundings, and the number of fertilizers and reagents is considerable, and since the fertilization and reagent area are enormous, fertilization and It is common to carry out reagents.

However, when carrying out fertilization and reagents using a mobile vehicle, there is a problem that a relatively large time, personnel, and expense are required for fertilization or reagents. In addition, it is not easy to uniformly spread the fertilizer or medicament on the object, and there is a problem in that the fertilizer and reagent time is lost when the fertilizing and reagent time is extended.

In order to solve this problem, technologies for applying fertilizers or reagents in a sprinkler method, which pressurizes irrigation water and pumps water, and sprays water from the drains or fountains, have been developed. In this sprinkler type fertilizer and reagent technology, a plurality of branch pipes are connected to the main pipe connected to the pump for pressurization, and a sprinkler or a fountain device is mounted at one end of the branch pipe that is displayed on the ground. A hydrostatic valve arrangement is used to deliver fertilization or reagents.

1A to 1D are views for explaining the operation of the conventional water level valve device.

In FIG. 1A, the upper side A of the hydrostatic valve is about 0.5 kg / cm 2 at the pressure pushing the valve disc 110. Therefore, in order to open the valve by pushing the valve lower primary side B up to open the valve, the valve disk 110 must be pushed up to a pressure of at least 0.5 kg / cm 2 or more to open the water level valve.

When the induction pipe D is installed as shown in FIG. 1B, when the primary water supply pressure of FIG. 1B is 7 kg / cm 2, the primary pressure is transmitted to the diaphragm pressure chamber 120 through the induction pipe D. The kg / cm 2 and the pressure originally held together add up to 7.5 kg / cm 2. At this time, since the pressure on the B side is 7 kg / cm 2 equal to the pressure on the primary side, the water level valve is closed.

When installing the induction pipe E as shown in Figure 1c, the water supply pressure of the primary side enters the valve upper A through the induction pipe of the D and the incoming pressure is discharged to the secondary side through the induction pipe E. Therefore, the valve upper side A is the pressure 0.5 kg / ㎠ originally pressed and the B side pressure is 7 kg / ㎠, the primary water supply pressure to lift the valve disk 110 to open the water level valve.

If the solenoid (Solenoid) is provided in the induction tube E as shown in Figure 1d, the induction tube of E is blocked as long as the electron valve is not opened, as in the case of Figure 1b. Therefore, the water level valve is closed. As shown in FIG. 1D, the electromagnetic valve plays a very important role in the hydrostatic valve device. When the power supply 220V is supplied to the electromagnetic valve, the electromagnetic valve is opened by the electromagnet, and when the power is cut off, the solenoid valve is opened and closed according to the ON / OFF of the electromagnetic valve.

However, if impurities such as fine rust residues enter the opening and closing of the electron valve, malfunction may occur. In addition, when the water level valve is opened and closed repeatedly due to rapid ON / OFF operation or automatic adjustment of the water level, water hammering action occurs, which causes a strong shock to pipes and valves, etc., causing breakage and noise vibration.

The present invention for solving the above problems, when supplying irrigation water such as water or liquid fertilizer along the long branch pipe to the watering device spraying water or liquid fertilizer to a large farming complex or outdoor golf course through the control of the water level valve device, By controlling the opening and closing of the electric ball valve provided in the valve device at a remote location, the water level valve device is operated so that irrigation water such as water or liquid ratio can be supplied to the watering device. The purpose is to provide a valve system.

A hole 306 for injecting fluid into the secondary outlet is formed, and the hole of the first diaphragm 312 is introduced so that the fluid at the primary inlet is introduced into the secondary outlet according to the opening and closing operation. The valve disc 314 is in contact with 306, and a second diaphragm 316 is connected to the valve disc 314 from an upper wall in the valve frame 310 to form a diaphragm pressure chamber 320. The primary inlet 302 and the diaphragm pressure chamber 320 are connected through the first induction pipe D, and the diaphragm pressure chamber 320 and the secondary side outlet 304 are connected to the second induction pipe E. Connected through the fluid in the diaphragm pressure chamber An electric ball valve 324 is provided in the second induction pipe E for controlling the fluid pressure by transmitting a force to the secondary outlet 304 through the second induction pipe E. The opening and closing of the valve 324 adjusts the pressure of the diaphragm pressure chamber 320, and opens and closes the valve disk 314 in accordance with the pressure control of the diaphragm pressure chamber 320, and of the valve disk 314 A hydrostatic valve device may be provided that is configured to deliver or shut off the fluid at the primary inlet 302 to the secondary outlet 304 through opening and closing.

Here, the electric ball valve is connected to the central control device for transmitting a predetermined control command via a wired communication network, and the opening and closing operation according to the predetermined control command transmitted from the central control device through the wired communication network. have.

The electric ball valve can be closed.

In addition, the driving unit stops the operation of the opening operation unit according to a power off signal, and only the closing operation unit is operated, and after a predetermined time passes after the closing operation unit operates the power supply through the power cut-off unit. You can block them all.

According to the present invention, there is no need to use a mobile vehicle when fertilizing or applying fertilizers or reagents to a large agricultural complex or an outdoor golf course with a large fertilizer or reagent area. Thus, relatively little time, personnel and expense are required for fertilization or reagents.

In addition, by uniformly installing the branch pipe spraying the fluid delivered from the main pipe can be evenly sprayed fertilizer or medicament to the object, even when the fertilizer and reagent time is extended can be timely spraying of the fertilizer or reagent. .

In addition, the conventional electronic valve opening and closing the fine rust residues, such as impurities in the opening portion may cause a malfunction, but by using the electric ball valve according to the present invention there is no problem in the sprinkling operation even if fine impurities such as fine residues.

In addition, when the opening and closing are repeated due to the rapid on / off operation of the electronic valve or the automatic adjustment of the water level, the water hammering action occurs, giving a strong impact to pipes and valves, etc. As the electric ball valve is used, the impact applied to the pipes and the valves can be alleviated, and the damage and noise vibration can be reduced.
