Description
Technical Field
The utility model belongs to the technical field of tunnel engineering drainage under water, in particular to but diversion control flap valve for drainage.
Background
With the development of society and the continuous improvement of people's traffic demand, more and more underwater tunnels are built. Because the underwater tunnel is designed to be a V-shaped slope, the structure has large water leakage amount and the lowest point, and the tunnel wastewater cannot be discharged automatically, a large-scale wastewater pump room is generally arranged at the lowest point of the tunnel to bear the wastewater discharge of the whole tunnel. The underwater tunnel waste water discharge is one of the key factors related to the tunnel operation safety.
In order to desilt, maintain and repair and store accident wastewater in emergency in a dry pond, a water collecting pond of an underwater tunnel wastewater pump room is generally divided into a plurality of chambers which are separated by partition walls, and communication valves are installed on the wall bodies. The valves such as gate valves, butterfly valves and the like are easily affected by sludge and have opening and closing faults, so that the communicating valves mostly adopt gates or flap valves, and the flap valves are most widely applied to drainage engineering.
The traditional flap valve is mostly controlled by a screw-type headstock gear, the headstock gear controls the opening of a valve through a screw, the valve realizes one-way sealing by means of dead weight and one-way water pressure, and the flap valve has the following defects: 1. the headstock gear and the valve body are required to be vertically arranged, so that the installation position of the flap valve body is limited, the area of a pump room is required to be enlarged for creating installation conditions, and huge waste is caused; 2. the water bins which need to be communicated and have bidirectional sealing working conditions, such as a wastewater pump house water collecting tank sub-bin, need to be provided with traditional flap valves at two sides of the wall body of the intermediate wall so as to realize bidirectional sealing and cause inconvenience and waste in installation. 3. The screw type hoist relies on the screw rod to open the flap valve, and screw rod length is restricted, has restricted the difference in height between valve body and the hoist, and for large-scale underwater tunnel waste water pump houses such as submarine tunnel, the catch basin degree of depth is big, and the catch basin bottom is big apart from pump house bottom plate difference in height, and ordinary flap valve is difficult to satisfy the requirement.
In summary, in view of the practical requirements in the field of underwater tunnel engineering drainage and the defects of the traditional flap valve, a water collecting tank communicating valve which is convenient and simple to install, can realize bidirectional sealing and is not limited by the installation height is needed in the field of underwater tunnel engineering drainage.
Disclosure of Invention
The utility model discloses to the technical problem who exists among the prior art, provide a drainage is with convertible control flap valve, simple to operate is simple, can realize two-way airtight, do not receive the mounting height restriction, reduces the pump house scale, reduces the investment, provides a convenient efficient intercommunication means for waste water pump house catch basin branch storehouse.
The utility model adopts the technical proposal that: a drainage directional control flap valve comprises a valve closing opening and closing machine, a valve opening and closing machine, guide pulleys, an anchoring bolt, a flap valve body, a valve closing guide rope and a valve opening guide rope, wherein the valve closing guide rope and the valve opening guide rope are respectively connected to two sides of the flap valve body, the valve opening guide rope is connected with the valve opening and closing machine after being changed in direction through the guide pulleys, the valve closing guide rope is connected with the valve closing opening and closing machine after being changed in direction through a plurality of guide pulleys, and the guide pulleys are fixed on a structure through the anchoring bolt.
Preferably, the flap valve body is positioned between the water collecting tank and the emergency sump, the valve opening guide rope is positioned on one side of the water collecting tank, the valve closing guide rope is positioned on one side of the emergency sump, and the valve closing hoist and the valve opening hoist are positioned in the pump room.
The opening and closing device of the direction-variable control flap valve is connected with the flap valve body through a high-strength corrosion-resistant guide rope, the direction and the path of the guide rope can be changed through a guide pulley which is pre-embedded or anchored on a structure, the installation of the flap valve body is not restricted by the relative position between the flap valve body and the opening and closing device and is not limited by the installation height, and therefore the opening and closing device and the flap valve body are installed in a separated mode.
When the flap valve is converted from the opening state to the closing state, the locking device of the rope hoist connected to one side of the flap valve body in the opening direction is closed, and the guide rope on one side of the flap valve in the opening direction can be freely released; the rope hoist connected to one side of the valve in the closing direction is started, the rope hoist acts on the flap valve body through the guide rope, the flap valve body is pulled to be in a closed state, after the valve is completely closed, the rope hoist locking device on the side is started, the flap valve body is in a closed state under the continuous binding effect of the guide rope, and therefore bidirectional sealing of two sides of the valve body is achieved.
When the flap valve is converted from a closed state to an open state, the rope type hoist locking device connected to one side of the flap valve body in the closing direction is closed, and the guide rope on one side of the flap valve in the closing direction can be freely released; the rope hoist connected to one side of the valve opening direction is started, the rope hoist acts on the flap valve body through the guide rope, the flap valve body is pulled to be in an opening state, after the valve is completely opened, the rope hoist locking device on the side is started, the flap valve body is in an opening state under the continuous binding effect of the guide rope, and the two sides of the valve body are communicated.
Compared with the prior art, the utility model discloses the beneficial effect who has is: on one hand, the utility model can realize the separated installation of the opening and closing device and the flap valve body, effectively solves the problem that the traditional flap valve is limited by the relative position between the flap valve body and the opening and closing device and the installation height, and can make the pump room more compact and flexible; on the other hand, can only realize the one-way airtight of valve body for the tradition claps the door, the utility model discloses can realize the two-way airtight of valve body both sides.
