Abstract
A constant flow water distribution device mainly solves the problems of the prior gate valve or stop valve including frequent control operation by operator, time consuming, labor consuming and difficult control of water injection rate in time and accurately during controlling water injection rate. The utility model is characterized in that: a valve body (1) has a middle cavity (5) and a bottom annular cavity (6); the valve body (1) arranged at the outside of the middle cavity (5) is provided with a water inlet valve (2), a water outlet valve (3) and a constant flow blocking device (4); the bottom annular cavity (6) is respectively communicated with the water inlet valve (2) and the constant flow blocking device (4), while the middle cavity (5) is respectively communicated with the water outlet valve (3) and the constant flow blocking device (4). The utility model can control water injection rate automatically and has the characteristics of compact structure and accurate control of water flow.
Description
Technical field:
The utility model relates to a kind of ground water-injection control device, especially constant current water dispensing apparatus used in the oil recovery field, oil field.
Background technology:
At present, oilfield water extraction crude oil is a kind of oil recovery means of using always, and gate valve or stop valve control water injection rate are generally adopted in the ground water filling.Uncertain or when changing when pump pressure or strata pressure, need manual control gate valve or stop valve to realize control to water injection rate, the operator controls frequently, wastes time and energy, and is difficult to control timely and accurately water injection rate, the normal production of recovering the oil of influence.
The utility model content:
For overcome the control of existing gate valve or stop valve during water injection rate the operator control frequently, waste time and energy and be difficult to control timely and accurately the deficiency of water injection rate, the utility model provides a kind of constant current water dispensing apparatus, this constant current water dispensing apparatus can be finished the control of water injection rate automatically, has compact conformation, control water yield characteristic of accurate.
The technical solution of the utility model is: this constant current water dispensing apparatus comprises valve body, valve body has middle cavity and base circle chamber, on the valve body in the middle cavity outside water intaking valve, outlet valve and constant flow blanking plug are installed, the base circle chamber communicates with water intaking valve and constant flow blanking plug respectively, and middle cavity communicates with outlet valve and constant flow blanking plug respectively.
The utlity model has following beneficial effect: owing to take such scheme, press water enters the base circle chamber by water intaking valve, enters middle cavity through constant flow blanking plug again, injects waterflood-transmission line by outlet valve at last.Constant flow blanking plug can be regulated water injection rate automatically, makes water injection rate keep steady state value.This apparatus structure compactness, without the Artificial Control water injection rate, the control water yield is accurate.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is A-A sectional views among Fig. 1.
1-valve body among the figure, 2-water intaking valve, 3-outlet valve, 4-constant flow blanking plug, 5-middle cavity, 6-base circle chamber.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By Fig. 1 in conjunction with shown in Figure 2, this constant current water dispensing apparatus comprises valve body 1, valve body 1 has middle cavity 5 and base circle chamber 6, on the valve body 1 in middle cavity 5 outsides water intaking valve 2 is installed, outlet valve 3 and constant flow blanking plug 4, constant flow blanking plug 4 is a spring-loaded plunger formula constant-current device, the groundwork principle is to utilize the elastic force of pretensioned spring to come balance to import and export the pressure of front and back, make the pressure reduction before and after importing and exporting keep constant, thereby guarantee that the flow by constant flow blanking plug 4 is a constant, reach the purpose of constant flow rate, constant flow blanking plug 4 belongs to prior art, and its structure is not given unnecessary details at this.Base circle chamber 6 communicates with water intaking valve 2 and constant flow blanking plug 4 respectively, and middle cavity 5 communicates with outlet valve 3 and constant flow blanking plug 4 respectively.
During actual the use, press water enters base circle chamber 6 by water intaking valve 2, enters middle cavity 5 through constant flow blanking plug 4 again, injects waterflood-transmission line by outlet valve 3 at last.Constant flow blanking plug 4 can be regulated water injection rate automatically, makes water injection rate keep steady state value.This apparatus structure compactness, without the Artificial Control water injection rate, the control water yield is accurate.
