Abstract
The utility model relates to an opening and closing device for a bottom valve of a water pump. The opening and closing device comprises the water pump which is arranged on a basic plane, a water suction pipe and a water drain pipe are arranged on the water pump, the bottom valve is arranged in the water suction pipe, a lever is arranged at the lower end of the bottom valve, one end of the lever is hinged with the wall of the water suction pipe, the other end of the lever is tied with a steel wire rope, a handle is hinged on the basic plane and connected with the steel wire rope, an ejector pin used for ejecting a spool of the bottom valve is arranged on the lever, a steel pipe is arranged outside the steel wire rope and connected with the lower surface of the basic plane, and a support is arranged between the outer wall of the steel pipe and the outer wall of the water suction pipe. The bottom valve of the water pump is prevented from being blocked by sundries, organizing labor to pull up the water suction pipe and the bottom valve of the water pump for maintenance is not needed, labor intensity is reduced, production efficiency is improved, persons are protected from falling into liquid during pulling, and unnecessary casualties are avoided.
Description
Technical field
The utility model relates to a kind of opening and closing device, and particularly a kind of bottom valve of water pump of controlling is opened and the device that closes.
Background technique
Water pump in the industries such as water supply, metallurgy, water treatment is equipped with bottom valve mostly, and bottom valve of water pump is a kind of valve of energy saving, generally is installed in the bottom of water pump suction pipe, and the liquid in the restriction water pump suction pipe returns the water source, plays the function of only import but no export.During general pump operation, bottom valve of water pump is opened, and liquid is from the valve body suction sleeve of entering, and when water pump was stopped transport, bottom valve of water pump was closed.There is such problem in such bottom valve of water pump switching mode: bottom valve of water pump is blocked by foreign material easily, causes the pump sump liquid in pipe to return the water source, and water pump is taken out not water outlet.Just need to organize this moment manpower that suction sleeve and bottom valve of water pump are dragged and place under repair, increase labor intensity, affect production, the while also can have the drop situation of liquid of people in pulling process, caused unnecessary casualties.
The model utility content
The utility model purpose is that a kind of bottom valve of water pump opening and closing device of having avoided bottom valve of water pump to be blocked by foreign material is provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of bottom valve of water pump opening and closing device comprises water pump, described water pump is arranged on the base plane, be connected with suction sleeve and waste pipe on the described water pump, be provided with bottom valve in the described suction sleeve, the lower end of described bottom valve is provided with lever; One end of described lever and suction tube wall hinge, there is wire rope in the other end system; Described base plane upper hinge has handle; Described handle links to each other with wire rope; Described lever is provided be used to the thimble that backs down the bottom valve spool.
Preferably, described wire rope is provided with steel pipe outward; Described steel pipe links to each other with the base plane lower surface.
Preferably, be provided with supporting element between described outer wall of steel pipe and suction sleeve outer wall.
Because the utilization of technique scheme, the utility model compared with prior art has following advantages:
Bottom valve of water pump opening and closing device of the present utility model when bottom valve of water pump need to be opened, is pressed lower handle, handle drives wire rope and moves upward, and wire rope hauls lever one end and rotates up, and the thimble that is arranged on the lever moves upward, back down the bottom valve spool, liquid is from the bottom valve valve body suction sleeve of entering; When bottom valve of water pump need to be closed, handle upwards lifted, and wire rope moves downward, and hauled lever one end and was rotated down, and thimble moves downward, away from the bottom valve spool.When bottom valve of water pump is blocked by foreign material, can repeatedly press and lift handle, so that thimble is done up and down to-and-fro motion, liquid can produce eddy current, and eddy current can wash away foreign material, avoided bottom valve of water pump to be blocked by foreign material, do not need to organize manpower that suction sleeve and bottom valve of water pump are dragged and place under repair, reduced labor intensity, increased manufacturing efficiency, the drop situation of liquid of the personnel that also avoided simultaneously occurring in pulling process has been avoided unnecessary casualties.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of bottom valve of water pump opening and closing device of the present utility model;
Wherein: 1, water pump; 2, base plane; 3, suction sleeve; 4, waste pipe; 5, bottom valve; 6, lever; 7, wire rope; 8, handle; 9, steel pipe; 10, supporting element; 11, thimble.
Embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Described in the utility model a kind of bottom valve of water pump opening and closing device as shown in Figure 1, comprise water pump 1, described water pump 1 is arranged on the base plane 2, is connected with suction sleeve 3 and waste pipe 4 on the described water pump 1, be provided with bottom valve 5 in the described suction sleeve 3, the lower end of described bottom valve 5 is provided with lever 6; One end of described lever 6 and suction tube wall hinge, there is wire rope 7 in the other end system; Described base plane 2 upper hinges have handle 8; Described handle 8 links to each other with wire rope 7; The described wire rope 7 outer steel pipes 9 that are provided with; Described steel pipe 9 links to each other with base plane 2 lower surfaces; Be provided with supporting element 10 between described steel pipe 9 outer walls and suction sleeve 3 outer walls; Described lever 6 is provided be used to the thimble 11 that backs down bottom valve 5 spools.
When bottom valve of water pump 5 needs to open, press lower handle 8, handle 8 drives wire rope 7 and moves upward, wire rope 7 hauls lever 6 one ends and rotates up, and the thimble 11 that is arranged on the lever 6 moves upward, and backs down bottom valve 5 spools, liquid is discharged from waste pipe 4 from the bottom valve 5 valve bodies suction sleeve 3 of entering; When bottom valve of water pump 5 need to be closed, handle 8 upwards lifted, and handle 8 drives wire rope 7 and moves downward, and hauls lever 6 one ends and is rotated down, and thimble 11 moves downward, and away from bottom valve 5 spools, liquid just can be from the bottom valve valve body suction sleeve of entering.
When bottom valve of water pump 5 is blocked by foreign material, can repeatedly press and lift handle 8, so that thimble 11 is done up and down to-and-fro motion, liquid can produce eddy current, and eddy current can wash away foreign material, avoided bottom valve of water pump 5 to be blocked by foreign material, do not need to organize manpower that suction sleeve 3 and bottom valve of water pump 5 are dragged and place under repair, reduced labor intensity, increased manufacturing efficiency, the drop situation of liquid of the personnel that also avoided simultaneously occurring in pulling process has been avoided unnecessary casualties.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, all drop within the utility model rights protection scope.
