Problems solved by technology

However, the motors of these water distributors have to overcome the pressure of the underground high-pressure water on the valve core, which increases the power of the motor and the force on the screw, which limits the cable length of the electric smart water distributor and the life of the water distributor.

Abstract

The invention relates to a bionic balance static-pressure valve. A valve element, a lower sealing structure, a valve element driving mechanism and an upper sealing structure are sequentially arranged in a valve body of the bionic balance static-pressure valve, the valve element driving mechanism is connected with the valve element, the lower sealing structure comprises a lower welded corrugated pipe and a lower corrugated pipe joint, the lower welded corrugated pipe sleeves the valve element, the upper end and the lower end of the lower welded corrugated pipe are respectively welded with the lower corrugated pipe joint and the valve element, the upper sealing structure comprises an upper welded corrugated pipe, a sliding sealing cover and an upper corrugated pipe joint, the upper end and the lower end of the upper welded corrugated pipe are respectively welded with the sliding sealing cover and the upper corrugated pipe joint, a valve bin sealing cover is arranged on the upper portion of the sliding sealing cover and is limited by a pressure cover, a gap between the sliding sealing cover and the lower welded corrugated pipe is completely filled with oil, and a balance static-pressure opening is formed in the valve body, corresponds to the sliding sealing cover and is communicated with a main water injecting pipeline. The bionic balance static-pressure valve has the advantages that the valve element position control precision can be improved, abrasion on a lead screw can be reduced, and the size, power and heat of a control motor can be decreased.

Description

technical field [0001] The invention relates to a valve, in particular to a bionic balance static pressure valve. Background technique [0002] At present, some electric intelligent water distributors have been installed in major oil fields across the country. The main function of these water distributors is to accurately inject water into different oil layers to ensure the pressure of each oil layer, thereby ensuring oil recovery efficiency. Because some oil layers are far away from the ground, the water injection pressure is increased, and the cable length of the electric smart water distributor is increased, which makes it very difficult for the electric water distributor to be used in deeper oil layers. [0003] Existing electric water distributors generally use a screw nut mechanism to control the movement of the spool with a motor, so as to achieve the purpose of controlling the water injection volume of each oil layer. However, the motors of these water distributors ...
