Abstract
The invention relates to a thermal insulation electrohydraulic high-temperature four-way ball valve capable of being used in high-temperature pipelines. Outside the valve is casted or welded an insulating casing connected with an inlet-outlet pipe. The warm-keeping fluid is heated cyclically in the inlet-outlet pipe. The inventive valve is driven by a permanent-magnet motor and electricity and can control the flow of the four-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 four-way 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 dissolve in the cylinder, make gas drive move cisco unity malfunction.
The objective of the invention is:
A kind of heat insulation electrohydraulic high temperature four way ball valve is provided, can uses the four way ball valve on pipeline, 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 desirable a few days ago update product, and safe and reliable realization telecontrol is regulated one-in-and-two-out or one-in-and-one-out, or one close one and open, and one opens two passes, and two close one opens, and two open a four-way transfer medium flow that closes.
The object of the present invention is achieved like this:
A kind of heat insulation electrohydraulic high temperature four 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.Valve body is cast with outward or the heat-preservating shell of burn-oning is managed mechanical connection with turnover, and the circulation of insulation liquid turnover pipe is incubated.Ball core top is connected with sense of rotation positioning device shaft 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 closed one at the one-in-and-two-out of telecontrol permanent magnet motor electric high-temperature pipeline under the high-temperature condition or one-in-and-one-out or and be opened, and one opens two passes, and two close one opens, and two open the four-way purpose of a pass.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 heat insulation electrohydraulic high temperature four way ball valve embodiment's a longitudinal sectional drawing.
