Description
Technical Field
The invention particularly relates to a valve well emptying valve, and belongs to the field of equipment in the sewage treatment industry.
Background
In the current sewage treatment industry, valve wells are built in buildings such as an oxidation ditch, a secondary sedimentation tank, a mud storage tank and a sedimentation tank, blow-down pipes and blow-down valves are arranged in the wells, and the blow-down valves adopt disc valves, gate valves, knife valves and the like in the prior art. Because such valves are not opened once a year, a significant amount of a mixture of sludge and waste is deposited in the blow-down pipe in front of the blow-down valve. They are extremely prone to be coagulated into blocks and lose fluidity due to long-time deposition and long-time sunlight exposure, and cause the blockage of the blow-down pipes and the blow-down valves, so that sewage in the ditch or the pool cannot be discharged normally.
When the sewage in the ditch or the pool needs to be emptied, the emptying valve is opened, and the sewage cannot be discharged. Because the blow-down pipe in the front of the blow-down valve is blocked by the mixture of long-term deposited, solar insolated and agglomerated sludge and garbage.
When the condition is met, the valve is manually placed in the valve well, the emptying valve is opened, the high-pressure water gun is repeatedly used for repeatedly flushing the valve port of the emptying valve, even the emptying pipe is required to be plugged and soaked in water, after the emptying valve and sludge dirt in the emptying pipe are softened, the high-pressure water gun is used for repeatedly flushing the emptying valve and the sludge dirt in the emptying pipe, so that the operation is repeatedly repeated, and the sludge dirt can be flushed out and discharged for many times. The whole process is time-consuming, more manpower and material resources are needed to be used, the difficulty is high, and the labor intensity is high. Because the emptying valve is always arranged in the valve well, the valve well is deeper, the space is small, the operation difficulty is very high, the body is easy to be injured by the falling operation, and the sprayed sewage is very easy to splash on the staff, so that personal injury is caused.
Even if the blow-down valve can normally discharge, the operator is required to go down into the valve well to open the blow-down valve, and when the blow-down valve is opened to one third of the degree, a large amount of high-pressure sewage is sprayed out. The high-pressure sewage sprayed out can rebound rapidly when the high-pressure sewage bumps against the well wall, and the rebound sewage is very easy to spray on operators, so that personal safety threat to the operators is formed, therefore, the emptying valve is always opened less than half to be forced to stop operation, the operators also need to rapidly spill out of the valve well, the emptying time is long, and the working efficiency and the production efficiency are directly influenced.
In order to overcome the above drawbacks, it is important to develop a valve well emptying valve which can be easily opened or closed on the well surface of the valve well without going down the valve well.

The working principle of the valve well emptying valve is as follows:
1. opening the valve
The protection cover is hung by a lifting hook, the inner square four sides of a sliding block arranged in a hollow circle of an operating rod are inserted into the outer square four sides of the head part of the valve rod, the position of a proper pin hole on the operating rod is selected according to the depth of a valve well, a hand wheel is moved to the position, a self-locking pin rod is penetrated, a hand wheel is fixed, then the hand wheel is rotated anticlockwise, the hand wheel transmits power to the self-locking pin rod through the pin hole on the hand wheel seat, the self-locking pin rod drives the operating rod to rotate in the same direction, the operating rod pushes a boss through a guide groove, the boss drives the outer square four sides of the head part of the valve rod to rotate in the same direction through the inner square four sides of the sliding block, so that the valve rod is driven to rotate in the same direction with the valve rod nut under the supporting action of the valve rod seat and the supporting rod, the bearing seat is pulled upwards simultaneously, and the valve plate is pulled upwards through the pin rod when the bearing seat is pulled upwards, so that the emptying valve is opened. When the gland touches the valve rod seat, the emptying valve is opened to the maximum position, and the hand wheel can not rotate any more.
The valve rod continuously ascends while rotating with the valve rod nut in a threaded manner, a reaction force is applied to the sliding block to push the sliding block to synchronously ascend, the sliding block slides upwards along the guide groove by virtue of a boss inserted in the guide groove of the operating rod, and the sliding block synchronously ascends with the valve rod to enter into a hollow circle of the operating rod, so that the pushing force of the valve rod on the operating rod is solved, and the operating rod can always keep the position unchanged by depending on the weight of the operating rod.
2. Closing
The hand wheel is rotated clockwise, the hand wheel transmits power to the self-locking pin rod through a pin rod hole on the hand wheel seat, the self-locking pin rod drives the operation rod to rotate in the same direction, the operation rod drives the boss through the guide groove, the boss drives the outer square four sides of the head of the valve rod to rotate through the inner square four sides of the sliding block, so that the valve rod is driven to rotate in the same direction, the valve rod and the valve rod nut rotate downwards under the supporting action of the valve rod seat and the supporting rod, meanwhile, the bearing seat is extruded to force the bearing seat to downwards, and meanwhile, the valve plate is extruded to downwards through the pin rod, so that the emptying valve is closed. When the valve plate hits the junction of the valve body L and the valve body R, the blow-down valve is completely closed and the hand wheel will not be able to rotate any further.
In this process, the slider follows, and the condition that the emptying valve is opened does not occur.
Operators stand on the well surface of the valve well in the two processes.
3. Dredging device
When the second valve well emptying valve in the valve well is blocked by the sludge dirt of the junction plate, one end of the water hose is connected to a fire-fighting water source or other high-pressure water sources, and the other end of the water hose is connected to a quick pipe connector of the valve well emptying valve. And (3) opening a high-pressure water source, flushing a check valve by the high-pressure water through a quick pipe joint, and finally directly spraying the high-pressure water onto the sludge dirt of the second valve well emptying valve and the emptying pipe inner junction plate under the boosting action of the spray nozzle. The mud dirt of the caking plate is continuously ulcerated and dissolved under the impact action of high-pressure water and is discharged out of the second valve well emptying valve and the emptying pipe together with the sewage, so that the second valve well emptying valve and the emptying pipe are dredged, and the sewage in the ditch or the pool can be normally discharged.
When the second valve well emptying valve can normally discharge, the high-pressure water source is stopped, the check valve is closed under the pressure effect of sewage in the second valve well emptying valve, the outflow of sewage is cut off, and the sewage in the second valve well emptying valve is prevented from flowing out of the emptying valve body.
4. Mounting and hanging-off of protective cover
1. Hanging off
When the second valve well emptying valve needs to be opened, the protective cover is hung off to perform the opening action.
2. Mounting
When the second valve well emptying valve is temporarily not used any more after the work is finished, the operating part is taken out, the protective cover is mounted on the outer circle of the valve rod nut by using the hanging hook through the U-shaped hanging ring above the protective cover, and dust and water vapor are prevented from corroding the threaded matching part of the valve rod and the valve rod nut and the outer square tetrahedron of the valve rod head.
