Abstract
The invention provided a cone Z-shaped valve core typed electric four-way valve, belonging to the design, manufacture and application technical field of valves. The cone Z-shaped valve core typed electric four-way valve is characterized in that four liquid pipes which are vertical to each other extend outwards on the same plane below a thick wall with the internal chamber being a taper cylindrical valve body; the center of a flange passes through a mainshaft; the upper part of the mainshaft is provided with a lead screw; the mainshaft sequentially passes through a Z-shaped valve core and an indexing rotation ring in a cone chamber, extends out two retainers downwards, is fixed on the main gear of a clapboard and engaged with the mainshaft lead screw by an internal thread. The mainshaft is closely fixed with the Z-shaped valve core and the indexing rotation ring. The indexing rotation ring extends out a pulling rod which faces to a limit switch. The main gear is engaged with a motor outlet shaft gear by a transition gear set. After the cone Z-shaped valve core typed electric four-way valve is executed, a water hammer phenomenon during flowing cutting is thoroughly eliminated, situations such as instant shutoff pressure, vibration, etc. are eliminated, the pre-stroke pipe section is greatly shortened, and the length of the whole machine is shortened by nearly 1/3 compared with an imported product; a volume pipe can be arranged on an automobile and taken as a movable verification platform, thus having wider and more convenient application.
Description
Technical field
The design, manufacturing, the applied technical field that belong to valve.
Background technique
Abroad the electric four passes switching valve (with the warlord) of " ball one valve bidirectional electric four-way type standard pipe prover " employing uses the mechanical gear transmission, make valve shaft do lifter motion, contract in the semicolumn valve block of two separation of drive, and the original place rotate switch to the position after, valve shaft makes valve block outwards expand downwards and supports, and barrel seals simultaneously.There are two deficiencys in this principle, the one, in when contracting by playing drainage circulation effect with the space of the about 2～3mm of inner tube wall, in the process that big flow switches, easily produce and turn to torsional moment to increase, instantaneous cutout promptly the build the pressure phenomenon and the shake of hydraulic shock and equipment occur.It two was about 8～12 seconds from rotateing in place to the sealing time, and this guide tube to the distance between the detecting switch just occurs, and very longly just to guarantee to move sender normal.
Summary of the invention
The invention provides a kind of in the process that big flow switches, can the generation and turn to torsional moment to increase, the phenomenon that builds the pressure of instantaneous cutout can not occur, do not have the shake of hydraulic shock and equipment; And guide tube is to the conical Z-shaped valve core type electric four-way valve of also not wanting very long distance between the detecting switch.
The technological scheme that the present invention takes is:
Conical Z-shaped valve core type electric four-way valve, comprise valve body and spool, its scheme is: a heavy wall, inner chamber is the below of tapered cylinder shape valve body, protruding mutually perpendicular four fluid-through tubes on the same horizontal plane, at the bottom of the valve by the band leak detector valve flange seal, the main shaft of top band screw mandrel passes in flange center, main shaft passes the master gear that the Z-shaped spool, the calibration that place the marginal zone seal ring in the cone cavity were turn-taked, stretched out two backstopping devices downwards and be fixed in dividing plate successively, and there are internal thread and the engagement of main shaft screw mandrel in the master gear center; Main shaft is also turn-taked fastening with Z-shaped spool, calibration; The calibration protruding driving lever of turn-taking has a motor steering limit switch facing to driving lever; Master gear is by the transition gear group of upper and lower two gears that are connected by axle, with the Motor Shaft gear engagement of the loam cake strip manual adjustment wheel that is fixed on valve; Remaining part all is sealed in the valve body.
Implementing good effect of the present invention is:
Owing to adopt the mechanical gear drive mechanism, with band Z-shaped spool of tapering and inner conical cylindrical shell structure, big trapezoidal seal ring combines with the conical surface and seals, turn to switch to reduce to turn round in four-way mouth upper end with the big lift technique of uniqueness and refuse, thoroughly eliminate water hammer when cutting stream, eliminated instantaneously build the pressure, situation such as shake, quick descending cushion seal, the fastest time is 3 seconds, cut apart smoothly naturally very much owing to the Z-shaped fluid of spool when descending, finish the effect of displacement fluid direction, realized the way traffic function of ball.The pretravel pipeline section is shortened greatly, and it is nearly 1/3rd to make that complete machine length has shortened than imported product, volume tube can be installed on the automobile, becomes movable verification platform, and purposes is more extensive and convenient.

Embodiment
Now the invention will be further described in conjunction with the accompanying drawings,
Conical Z-shaped valve core type electric four-way valve, comprise valve body and spool, it is characterized in that: a heavy wall, inner chamber is the below of tapered cylinder shape valve body 1, protruding mutually perpendicular four fluid-through tubes 2 on the same horizontal plane, flange 3 by band leak detector valve 18 at the bottom of the valve seals, the main shaft 4 of top band screw mandrel passes in flange center, main shaft passes the Z-shaped spool 5, the calibration that place the marginal zone seal ring 17 in the cone cavity successively and turn-takes 6, stretches out two backstopping devices 7 downwards and be fixed in the master gear 9 of dividing plate 8, and the master gear center has internal thread and screw mandrel to mesh; Main shaft is also turn-taked fastening with Z-shaped spool, calibration; The calibration protruding driving lever 10 of turn-taking has a motor steering limit switch 11 facing to driving lever; Master gear is with the motor 14 of manual adjustment wheels 16 to go out shaftgear 15 engagements by the transition gear group of upper and lower two gears that are connected by axle 12 with the upper cover plate 13 that is fixed on valve; Remaining part all is sealed in the valve body 1.
Now in conjunction with the accompanying drawings working principle of the present invention is explained,
When Motor Shaft drives master gear 9 by the transition gear group, the master gear center has internal thread and main shaft screw mandrel to mesh; Drag main shaft and rise, Z-shaped spool and calibration are turn-taked and are and then risen, and calibration is turn-taked and run into two backstopping devices 7 master gear under, and then rotates, and runs into motor steering limit switch 11 when driving lever, and motor oppositely drags, and finishes Z-shaped spool lifting and go to action at this moment.
