Abstract
The utility model provides a constant flow water distributor, comprising an upper cover of a valve body, a lower valve body, a water inlet pipe and a water outlet pipe to form a distributor body whose middle portion is provided with a cylinder sleeve. An adjusting rod is cooperatively connected with the upper end of the cylinder sleeve by the upper cover of the valve body. The lower portion of the cylinder sleeve is provided with a water inlet correspondingly connected with the water inlet pipe of the body. A hollow plunger piston device forms a sliding pair in the cylinder sleeve. The water inlet hole on the bottom portion is cooperated with the water inlet of the cylinder sleeve. The water outlet hole on the upper portion and the water outlet of the cylinder sleeve are communicated to form a water flow path. A constant pressure spring is arranged on the lower end of the plunger piston. The distributor adopts the cylinder sleeve and a plunger piston sliding assembly and makes use of the water flow pressure difference of the water inlet pipe and the water outlet pipe to control the sliding displacement of the plunger piston to control the water flow quantity in the distributor. The function of automatically adjusting the water injecting quantity by machinery is realized and the problems of that themanual control valve can not timely and accurately conduct water injecting to the oil well and oil production work and the water injecting work are influenced are solved.
Description
Technical field:
The utility model provides a kind of constant current mode water distributor, be used for water injection well in oil fields and control water injection rate automatically, be installed on the waterflood-transmission line of ground, under the situation that its function mainly is to work as pump pressure and strata pressure is uncertain or change, can regulate internal pressure automatically, guarantee the interval of its control or full well by the predetermined accurate water filling of injection allocation amount, belong to the oil field well with water distribution equipment technical field.
Background technique:
At present, generally be to use common valve control flushing in the oil field, comprise gate valve, stop valve etc., when pump pressure and strata pressure is uncertain or situation about changing under, can only finish injection allocation by manual tune valve control water yield realization flow equilibrium, waste time and energy, can't promptly and accurately carry out water filling, influenced water filling and oil extraction operation oil well.
Summary of the invention:
The utility model provides a kind of constant current mode water distributor, has solved problems such as waste of manpower that existing use valve hand-guided water injection rate brings, poor accuracy.
The utility model adopts following technical solution: by valve upper cover, following valve body and intake pipe and outlet pipe constitute the water distributor body, the middle part of water distributor body is provided with cylinder sleeve, adjustable lever is connected by valve upper cover and cylinder sleeve upper end, the bottom of cylinder sleeve has the corresponding connection of intake pipe of water intake and body, top is that the rotary valve of water outlet and adjustable lever is connected, hollow plunger assembly constitutes sliding pair in cylinder sleeve, match with the water intake of cylinder sleeve in the water inlet of side, the osculum on top is communicated with the formation flow channel with the water outlet of cylinder sleeve, the level pressure spring is installed in the lower end of plunger, it moves up and down may command, regulate water inlet, the size of water outlet, promptly control the water flow of water distributor, realized constant current mode water distribution purpose.
Under the working state, the elastic force of level pressure spring and plunger be pressure balance up and down.When this pressure reduction was bigger than normal or less than normal, under the level pressure spring action, plunger slided downward or upward automatically and changes cylinder sleeve water intake size, adjusts the cylinder sleeve internal pressure, the Spring balanced of pressure reduction and spring about plunger.During the work of constant current water distributor, plunger pressure reduction up and down is certain; Cylinder sleeve outlet port inside and outside differential pressure is certain, is not subjected to the constant current water distributor to come the pressure influence of water and water outlet.Therefore, after the cylinder sleeve water outlet was determined, flow was determined.The size of cylinder sleeve water outlet is regulated according to injection allocation amount size by adjustable lever.
Good effect of the present utility model is: adopt cylinder sleeve, plunger slip assembly in water distributor, utilize the slide displacement of the current pressure reduction control plunger of water inlet, outlet pipe, control water flow in the water distributor, realized mechanical automatic adjusting injection flow function, having solved manual control valve can't promptly and accurately carry out water filling to oil well, has influenced the problem of water filling and oil extraction operation.
