Abstract
A kind of deep well pump sand control check three-port structure, including outlet pipe, outlet pipe side wall are equipped with lateral discharge opening, are the water outlet of transverse direction below discharge opening, valve are equipped between discharge opening and water outlet, valve is hinged on outlet pipe；The inner face of the discharge opening is stretched into outlet pipe and is obliquely installed, and valve is closed in flow action lower cover on water outlet or discharge opening.The utility model provides a kind of deep well pump sand control check three-port structure, and the outlet end of well pump is mounted in as accessory, ensure in pump operation can with automatic-sealed tapping pipe, when shutdown can it is automatic we open tapping pipe, it is outer that the water in pipe is released pump.
Description
Technical field
The utility model belongs to water pump technology, refers in particular to a kind of deep well pump sand control check three-port structure.
Background technology
With the continuous decline of level of ground water, deep well pump makes deep well pump industry development at the ideal water lift of people
It is extremely rapid.Because level of ground water declines the emergence with high-rise building, it is desirable that deep-well pump lift is continuously improved, and is increased to by tens meters
Hundreds of meters of even upper kms.With the raising of pump lift, pump discharge is taken over also with the raising of lift and is lengthened, and substantially and raises
Journey and synchronize increase.When electric pump is shut down, ponding and sand grains in long long pipeline will be flowed to by blowback in well, and this reflux has
Two kinds of drawbacks, one is the motor meeting high speed reverse rotation in reflux course, capacitor-operated motor can become generator, defeated to lead-out wire
Go out electric current, if starting motor at this time, the electric current on both sides can be fought, and prodigious damage is caused to motor；Secondly the silt particle in water
It can be accumulated in pump when passing through pump, cause pump seizure and burn out motor.
In order to solve these drawbacks, many producers are provided with non-return valve (such as Fig. 3) in well pump exit site, to prevent to let out
Water, water are can to block, but new drawback occurs again, the silt particle in pipe can be deposited on non-return valve top, and silt particle is more to be made
Non-return valve can not be opened, and water pump cannot be discharged.In addition water is trapped in winter meeting bursting by freezing pipeline in outlet pipe.This several drawbacks at
" cancer " of well pump operation, causes the structural factor of these drawbacks to be all happened in well, cannot manually or manually method is gone
It solves, can only rely on and automatically control, therefore to have solved these problems prodigious difficulty, many water pump experts, scholar, engineer
It is all inquiring into, research attempts to solve these drawbacks, but never good method.
Utility model content
The purpose of this utility model is to provide a kind of deep well pump sand control check three-port structure, as accessory going out mounted in well pump
Mouthful end, ensure in pump operation can with automatic-sealed tapping pipe, when shutdown can it is automatic we open tapping pipe, the water in pipe is released
Pump is outer.
What the purpose of this utility model was realized in：A kind of deep well pump sand control check three-port structure, including outlet pipe, go out
Water pipe side wall is equipped with lateral discharge opening, is the water outlet of transverse direction below discharge opening, valve is equipped between discharge opening and water outlet,
Valve is hinged on outlet pipe；The inner face of the discharge opening is stretched into outlet pipe and is obliquely installed, and valve is under flow action
Lid closes on water outlet or discharge opening.
Wherein, the inner face angle of inclination of the discharge opening is 70 °.
Wherein, the discharge opening is radially plugged on outlet pipe by water discharging pipe and is formed, and water discharging pipe is solid by fastener
It is scheduled on outlet pipe.
The utility model is prominent and beneficial compared with prior art to be had the technical effect that：
The threeway of sand control check is mounted in pump discharge end as a well pump accessory, a series of using the energy progress for pumping itself
Action, valve opening close valve, and interlocking movement makes water outlet and return water according to scheduled trend of road, effectively controls water (flow) direction, makes
Outside the smooth discharge pump of sand water in outlet pipe, solves sand water and well pump is damaged.
Description of the drawings
State diagram when Fig. 1 is the utility model pump operation；
Fig. 2 is state diagram when the utility model pump is shut down；
Fig. 3 is the check valve structure figure of the existing well pump of the utility model.
Reference numeral：1, outlet pipe；1a, step surface；2, valve；3, discharge opening；4, water discharging pipe；5, fastener；6, go out
The mouth of a river；7, non-return valve.
Specific implementation mode
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings, referring to Fig. 1-2：
A kind of deep well pump sand control check three-port structure, including outlet pipe 1, outlet pipe 1 connects the pump housing, for drawing water upwards
Go out.It is provided with horizontal step surface 1a in outlet pipe 1, the radial sluicing being plugged on outlet pipe 1 is equipped on step surface 1a
Pipe fitting 4,4 inner end of water discharging pipe are stretched into outlet pipe 1 and are obliquely installed, and inclined-plane is arranged towards step surface 1a；4 outer end of water discharging pipe
It is connected and fixed by fastener 5 with outlet pipe 1；Sluicing pipe orifice forms discharge opening 3, and the endoporus at step surface 1a then forms water outlet
Valve 2 is arranged in mouth 6 between discharge opening 3 and water outlet 6,2 one end of valve is hinged on 1 inner wall of outlet pipe, and valve 2 is with working condition
Lid closes back and forth between discharge opening 3 and water outlet 6, to control water (flow) direction.
When water pump operation (as shown in Figure 1)
At runtime, the pressure of water outlet is very big for water pump, and upward active force can jack up valve 2, be pressed around branch suitable
Clockwise rotates, and opens water outlet 6, and when rotating to 70 °, valve 2 has blocked discharge opening 3, and water pump normally hoists confession
Water.
When water pump is shut down (as shown in Figure 2)
When water pump is shut down, under the action of return water downward force, valve 2 rotates counterclockwise around fulcrum, when
Valve 2 has blocked water outlet 6 when rotating to 0 °, while also opening discharge opening 3, by pipe water and silt particle to release pump outer.
So the threeway of sand control check is mounted in pump discharge end as a well pump accessory, one is carried out using the energy of itself is pumped
The action of series, valve opening close valve, and interlocking movement makes water outlet and return water according to scheduled trend of road, effective to control flow side
To, make outside the smooth discharge pump of sand water in outlet pipe 1, solve sand water to well pump damage.
Above-described embodiment is only the preferred embodiment of the utility model, not limits the protection model of the utility model according to this
It encloses, therefore：The equivalence changes that all structures, shape, principle according to the utility model are done, should all be covered by the protection of the utility model
Within the scope of.
