Description
Affiliated field:
The utility model relates to a kind of hand well from the underground suction and the water supply that hoists.
Background technology:
The hand well is used in the rural area extensively at present, is the main intake equipment of water commonly used in people's daily life.Traditional hand well comprises a pit shaft that is connected with foggara, be provided with a piston element of handling by depression bar in pit shaft, and delivery port is arranged on the top of pit shaft.Because the well of this kind structure is by the negative pressure that produces in the foggara water to be drawn onto on the ground from underground, so, in use, at first to add a certain amount of diversion in the piston element top in pit shaft, just can draw water with the extruding that realizes sealing back depression bar.If can not reach certain sealing effectiveness between piston and shaft in wall, pollution of waterhead in the well is easily caused in the piston element bottom of added diversion leakiness to the pit shaft, is difficult for realization simultaneously and normally draws water; In addition, this kind well can only be extracted water out ground, and it can not be sent to eminence, so the well of this kind structure is for very inapplicable as occasions such as remote water such as rural irrigation or eminence water supply.
CN2188135Y has announced a kind of name and has been called " the hydraulic pressure well tool that does not need to add diversion " technology, and its structure is that the piston element post is the shape cavate, is provided with the one way valve of band spring precompressed in the chamber of piston element body.Though the hydraulic pressure well sealing effectiveness of this structure makes moderate progress, the step that adds diversion when having solved in addition from underground suction, but piston element is the column cavate, and adopt spring mechanism to seal one way valve, make and realize sealing in the piston element chamber, so, the manufacture technology complexity of this piston element, the cost height, and this pumped well still can not will be sent to eminence from the underground water that drinks up, and still can not solve problems such as remote or eminence water.
In addition, CN87203189U has also announced a kind of name and has been called " miniature hand well pump " technology, and the used piston element of this well is made of two sealing plates and forbay up and down, and one way valve is arranged in the forbay, and outlet pipe and inlet opening are arranged up and down.This well forms certain pressure by the water that will extract ground out on piston top, and only by people's power ability pressure accumulation upward, could realize remote then or hoist sending water.But, water can be formed in the process of pressure, along with the increase of pressure, needed external force is big more, and the mode with regard to manpower is exerted oneself upward can not form bigger hydraulic pressure, causes the lift of water less relatively; Simultaneously, one way valve itself just has complex structure and is difficult to shortcoming such as makings, adds the requirement of aspect such as withstand voltage, causes its cost of manufacture raising.
Technical scheme:
The purpose of this utility model provides a kind of hand well that with the two kinds of force methods that make progress water also can be formed the manual operation of relative elevated pressures downwards from underground extraction that utilizes.
The hand well that the utility model proposed, has the pit shaft that one or two inside communicate, being provided with the upper end in this pit shaft flexibly connects with the depression bar end that has fulcrum, the piston element that the lower end cooperates with the shaft in wall tightness, be provided with the outlet pipeline that communicates with it and have the water outlet non retern valve in the pit shaft and in the following side of piston element maximum travel position, wellbore bottom is connected with inlet pipeline through the water inlet non retern valve after by water inlet non retern valve and/or intervalve again.
Described water outlet and water inlet non retern valve have a central region and have the flange of a plurality of vertical through holes and one and be arranged on above the flange and/or the ligulate valve of side, and the ligulate valve is that central region has a side that the square of cannelure or round rubber pad make and is fixed on tongue piece on the flange.
The above and below of described piston element is provided with sealing mat.
Described depression bar can be the rod member that a straight-bar or end regions have arc.
Described intervalve is a tee piece that an import and two outlets are arranged.
Described hand well has two outer walls and is linked to each other by fulcrum and the inner pit shaft that has piston element, and fulcrum and depression bar central region flexibly connect.
The fulcrum on the described pit shaft outer wall and the front end of depression bar or flexibly connect with the front end region of depression bar.
The upper end of described pit shaft inner carrier and the front end of depression bar or flexibly connect with the front end region of depression bar.
Because it is to be made of with the ligulate valve that can cover a plurality of vertical through holes the flange that central region has a plurality of vertical through holes that the utility model proposes water inlet non retern valve that the hand well adopts, the current of Inlet and outlet water are disperseed steadily, impact force diminishes, thereby improved the application life of ligulate valve, and good sealing effect; Secondly, adopt the twin-well barrel structure, all realize water inlet and water outlet continuously when making depression bar depress or lift, can improve the efficient of Inlet and outlet water, this operating process simultaneously is also laborsaving relatively; In addition, no matter the hand well of individual well barrel structure because depression bar adopts different positions with piston element is hinged, and is which position of employing all can be realized laborsaving.
