Abstract
The invention provides a high temperature three-way ball valve which is driven by electric liquid. It can be used on gas discharging pipe where the temperature is about 680 deg.C. It is driven by permanent magnetism motor, the structure is compact, the shape is handsome, the volume is small and the weight is light, it can be used and maintained conveniently.
Description
The present invention relates to the valve on a kind of high-temperature pipe, especially drives with direct current 24V starting 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 dissolve in the cylinder, make gas drive move cisco unity malfunction.
The objective of the invention is:
Provide a kind of electric liquid to drive high-temperature three-way ball valve, can use the tee ball valve on 680 ℃ of exhaust ducts, with the permanent magnet motor and the driving of surging, 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 liquid drives high-temperature three-way ball valve, it is characterized in that the monel metal material, has high temperature resistant characteristics.The ball of core band L type hole structure and valve body grind and coincide.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.Solenoid valve is 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 under 680 ℃ of situations of 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.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:
Figure one is circuit theory diagrams of the present invention.
Figure two is longitudinal sectional drawings that electric liquid drives high-temperature three-way ball valve embodiment.

In figure one: direct current supply line (20) and D.C. contactor (21) and permanent magnet motor, electric pile crown (19) is electrically connected.
In example shown in Figure 2:
Spheroid (34) seal ring (35) spool (25) material grinds and coincide with monel metal steel ability 680 ℃ of high pest, good seal performance, and close in one hole during 90 ° of spheroid (34) endoporus, and a through hole closes when returning, and another through hole is opened.Spheroid (34) top is connected with positioning work piece rotor shaft (14) pin (15) with spool (25), and the head capsule spare that surges (12) is connected by bolt (24) with middle frame (16), and middle frame (16) is connected with ball valve body (18) bolt (17).The head capsule body (12) that surges is connected with permanent magnet motor frame (4) bolt (8), the head axle (14) that surges is connected by pin (11) with permanent magnet motor rotor shaft (1), appear in permanent magnet motor rotor shaft (1) the top, so that the debugging maintenance is used, the outer cylinder body (12) that surges is opened a screw and pipe connects (22) and is threaded onto in the middle of the hydraulic pressure solenoid dress solenoid valve (23) and drives fluid head fuses (13) and drive rotating shafts (14) rotation via pins (15) drive ball spool (25) rotation through taking over (22), by solenoid valve controller (30) instruction hydraulic power, one open-one close, one closes 2 90 ° of ball core rotation drives of opening is rotated by seal ring (35) interior spheroid (34).
Permanent magnet motor starts stator, and (31 electric pile crowns (19) are electrically connected, and close electric current by electric pile crown (19) connecting line (20) and long-range the opening or closing of D.C. contactor (21).Direct current 24V electrical signal (20) leads at permanent magnet motor startup stator (31) power supply through D.C. contactor (21) by electric pile crown (19), make permanent magnet (6) drive motor rotor shaft (1) work, via pins (11) drive ball spool (25) rotation is by the threeway ball fuse rotation of limit control (29) instruction one-in-and-two-out or one-in-and-one-out.
Bearing (3), (7) are tightened up with bolt (10), (32) by gland (2), (9) permanent magnet motor rotor (5) by upper bearing (metal) (3) lower bearing (7).Valve body (18) inner spool (25) is by having compressed slip and seal action by filler (28) with screw (26) between following valve body (18) of Gland (27) and the spool (25).
