Abstract
An electrohydraulic high-temperature three-way ball valve for use in high-temperature pipelines is driven by a permanent-magnet motor and electricity. Because of its compact structure, small volume and light weight, it's easy for the three-way ball valve to be used, mounted and repaired. The inventive valve can realize the remote control of the flow of the three-way conversion medium.
Description
The present invention relates to the valve on a kind of high-temperature pipe, especially drives with DC start and control d.c. motor and threeway automatic is opened and one closed, one closes a valving of opening.
At present, known ball valve is by valve body, spool, filler, Gland, handle or install cylinder additional and form.Air cylinder driven is only used at low temperatures, and as high temperature, handle scalds one's hand and damages.As surpassing 250 ℃ of rubber bands that will melt in the cylinder, make gas drive move cisco unity malfunction.
The objective of the invention is:
A kind of electric and hydraulic high-temperature three-way ball valve is provided, can uses the tee ball valve on high-temperature pipe, drive with permanent magnet motor and electricity, compact structure, beautiful shape, volume is little, and is in light weight, uses I﹠M convenient.This valve is present desirable update product, and safe and reliable realization telecontrol is regulated one-in-and-two-out or one-in-and-one-out, threeway transfer medium flow.
The object of the present invention is achieved like this:
A kind of electric and hydraulic high-temperature three-way ball valve is characterized in that the monel metal material, has high temperature resistant characteristics.The ball of core band type hole structure and valve body grind and coincide.Ball core top is connected with sense of rotation positioning device shaft mechanical, and the motor rotor axle is connected with ball valve fuse rotor axis mechanical, and the fluid head fuse is connected with ball valve fuse rotor axis mechanical, and square toes are exposed in permanent magnet motor rotor shaft the top.The two poles of the earth are electrically connected on the permanent magnet motor stator, by connecting line and D.C. contactor remote switch or powered-down.
Owing to adopt such scheme, the present invention just can be at high temperature the one-in-and-two-out of telecontrol permanent magnet motor electric high-temperature pipeline or the threeway purpose of one-in-and-one-out under the situation.Be widely used in oilfield exploitation, natural gas exploration experimental project, engineerings such as high temperature strong corrosion dangerous situation.
The present invention is further described below in conjunction with drawings and Examples:
Fig. 1 is circuit theory diagrams of the present invention.
Fig. 2 is electric and hydraulic high-temperature three-way ball valve embodiment's a longitudinal sectional drawing.
