Description

Technical Field

[0001] The utility model relates to the technical field of steel dam gate control valves, in particular to a steel dam gate hydraulic control valve. Background Art

[0002] The hydraulic control valve of the steel dam gate has a precise structural design. It is mainly composed of a valve body, a valve core, a control chamber and a hydraulic control unit. The valve core adopts a flexible sealing structure. The guide groove is used to guide the water flow, and the control chamber is isolated by a sealing ring to prevent leakage. The hydraulic control unit includes an oil pump, an oil tank and a hydraulic valve to form a stable hydraulic system. In terms of structural principle, the valve controls the water flow by adjusting the position of the valve core, and the hydraulic pressure adjusts the opening and closing of the valve core, thereby achieving precise adjustment of the flow, pressure and water level. Its functions include flow regulation, pressure regulation, water level control, and it is widely used in irrigation and water conservancy projects. However, the current hydraulic control valve of the steel dam gate is mainly a single The valve body structure function is the same, that is, the valve body only has the ability of flow regulation, pressure regulation and water level control. Therefore, when controlling the steel dam gate fluid pressure, it is necessary to set control valves with different functions on the hydraulic pipeline, and each function requires an independent control valve to implement, which involves more pipeline connections and hydraulic components. This not only increases the difficulty of assembling the hydraulic system, but also increases the probability of system failure. In terms of the later maintenance of the hydraulic system, control valves with different functions also need to be maintained and repaired separately, and because multiple components are involved, more frequent inspections and more complicated maintenance procedures are required, which will bring additional economic burdens for the long-term operation and maintenance of water conservancy projects.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-4The utility model provides an embodiment: a hydraulic control valve for a steel dam gate, comprising an oil channel block 1 and an oil inlet 101 installed on the outer wall of one side of the oil channel block 1, two oil outlets on the front of the oil channel block 1 are installed with a plate-type stop valve 2 and a plate-type check valve 3, a second electromagnetic reversing valve 6 is installed on the outer wall of the other side of the oil channel block 1, and a first electromagnetic reversing valve 5 is installed at the oil outlet at the top of the oil channel block 1. The first electromagnetic reversing valve 5 and the second electromagnetic reversing valve 6 are used to realize the reversing function of the oil circuit. By controlling the on and off of the electromagnetic reversing valve, the flow direction of the liquid in the control valve can be changed, thereby realizing the reversing control of the hydraulic system of the steel dam gate;

[0018] The oil outlet on the back of the oil channel block 1 is equipped with a relief valve 7, which plays a role in pressure regulation on the oil channel block 1 of the control valve. When the pressure of the hydraulic system of the steel dam gate exceeds the set value, the relief valve 7 will open, so that the excess liquid will flow back to the oil tank to keep the system pressure stable and ensure the safety of the water conservancy project.

[0019] A plate-type stop valve 2 102 is installed at the oil outlet on the back of the oil channel block 1 above the overflow valve 7. There are two plate-type stop valves 2 102. The plate-type stop valve 1 2 and the plate-type stop valve 2 102 are connected to the hydraulic drive cylinders of each steel dam gate, which plays a role in controlling the flow of hydraulic oil. By adjusting the opening of the plate-type stop valve, the flow of the liquid flowing out of the control valve can be controlled.

[0020] Two bolt columns are installed on the outer wall of the oil passage block 1 on one side of the second electromagnetic reversing valve 6, one end of the bolt column extends to the inside of the oil passage block 1, and when the bolt column is removed from the oil passage block 1, two reserved openings will appear on the outer wall of the oil passage block 1 to facilitate the replenishment of the oil circuit;

[0021] The oil outlet at the top of the oil channel block 1 is installed with a superimposed hydraulically controlled one-way valve 4, and the oil outlet of the superimposed hydraulically controlled one-way valve 4 is connected to the oil inlet end of the first electromagnetic reversing valve 5. By installing the superimposed hydraulically controlled one-way valve 4 between the first electromagnetic reversing valve 5 and the oil channel block 1, the backflow of the hydraulic oil can be effectively prevented to ensure the normal operation and safety of the hydraulic system. At the same time, the superimposed hydraulically controlled one-way valve 4 can also ensure that the hydraulic oil flows in the correct direction to avoid instability in the hydraulic system.

[0022] Integrating multiple functional modules on the oil channel block 1 makes the overall structure of the control valve more compact and simple, and each functional module can be maintained and replaced independently without affecting the normal operation of other functional modules. Such a design can reduce the later maintenance cost of the hydraulic system of the steel dam gate;

[0023] An I-beam bracket 8 is fixed to the bottom end of the oil channel block 1, and studs 9 are installed on the top and bottom walls of the I-beam bracket 8. The length of the I-beam bracket 8 is the same as that of the oil channel block 1. The staff can fix the control valve to the installation plane through the studs 9 and the I-beam bracket 8.

[0024] When the embodiment of the present application is in use, first, the plate-type stop valve 1 2, the plate-type stop valve 2 102, the first electromagnetic reversing valve 5, the second electromagnetic reversing valve 6 and the overflow valve 7 are installed in sequence on the multiple oil outlets of the oil channel block 1, so that the control valve has a multi-way hydraulic oil cut-off function, an oil circuit reversing function and a high-pressure overflow protection function, and can realize the flow regulation, pressure regulation and water level control capabilities of the steel dam gate. Integrating multiple functions into one control valve can greatly simplify the structure of the system. Compared with setting multiple single-function control valves on the hydraulic pipeline, a multifunctional control valve can reduce the number of pipeline connections and hydraulic components, reduce the complexity of the system, and the procurement, installation and subsequent maintenance costs of a multifunctional control valve are more economical than those of multiple single-function control valves, which helps to quickly build a steel dam gate project.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
