Abstract
The utility model provides a D.C. actuated high temperature four-way exhaust valve which can drive a four-way exhaust valve used for 680 Celsius system of exhaust pipe with a permanent magnet motor and electricity. The utility model has a compact structure, a handsome appearance, a small volume, light weight and is convenient to install and maintain. The valve is current ideal updated product, is safe and reliable in realizing the remote control and adjustment of four-way conversion media flow of one-in-two-out or one-in-one-out, or one-off-one-on, one-on-two-off, two-off-one-on and two-on-one-off.
Description
The utility model relates to the valve on a kind of High Temperature Gas pipeline, 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 stopcock 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 purpose of this utility model is:
A kind of d.c. motor motor driving high-temperature four-way stopcock is provided, can uses the fourway plug valve on 680 ℃ of exhaust ducts, drive with permanent magnet motor and electricity, compact structure, aesthetic in appearance, 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, 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 purpose of this utility model is achieved in that
A kind of direct current drive high-temperature four-way smoke valve is characterized in that the monel metal material, has high temperature resistant characteristics.The cock of core band L type hole structure and valve body grind and coincide.The cock 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 utility model just can be under 680 ℃ of situations of high temperature the one-in-and-two-out or the one-in-and-one-out of length of run control permanent magnet motor electric high-temperature pipeline, or one close one and open, one opens two passes, two close one opens, two open the four-way purpose of a pass.Be widely used in oilfield exploitation, natural gas exploration experimental project, the application on the engineerings such as high temperature strong corrosion dangerous situation, particularly diesel engine high-temp waste gas absorption refrigeration heater device.
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is circuit theory diagrams of the present utility model.
Fig. 2 is direct current drive high-temperature four-way smoke valve embodiment's a longitudinal sectional drawing

In Fig. 1: 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:
Valve body spool (22) material grinds and coincide with 680 ℃ of high temperature of monel metal steel ability, good seal performance, and close in one hole during 90 ° of L types of spool (22) endoporus structure half-twist, and a through hole closes when returning, and another through hole is opened.Cock spool (22) top is connected with positioning work piece rotor shaft (14) pin (15), and positioning work piece shell spare (12) is connected with faucet valve (18) bolt (17) with middle frame (16).Positioning work piece housing (12) is connected with permanent magnet motor frame (4) bolt (8), and positioning work piece axle (14) and permanent magnet motor rotor shaft (1) are by pin (11); Connect permanent magnet motor rotor shaft (1) the top and appear, so that the debugging maintenance is used.
Permanent magnet motor starts stator (27) and is electrically connected with electric pile crown (19), closes 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) makes power supply lead on permanent magnet motor startup stator (27) through D.C. contactor (21) by electric pile crown (19), make permanent magnet (6) drive motor rotor shaft (1) work, via pins (11) drives stopcock fuse (25) rotation, by limit control (26) instruction one-in-and-two-out or one-in-and-one-out, or one close one and open, one opens two passes, and two close one opens, and two open a four way cock fuse rotation of closing.
Permanent magnet motor rotor (5) by upper bearing (metal) (3) lower bearing (7) bearing (3), (7) by gland (2), (9) with bolt (10), (28), tighten up.Valve body (18) inner spool (22) is by having compressed slip and seal action by filler (25) with screw (23) between following valve body (18) of Gland (24) and the spool (22).
