Description

The electric four passes selector valve

Technical field

The utility model relates to a kind of valve, specifically is a kind of electric four passes selector valve, is applicable to refrigeration and air-conditioning industry.Can also be as required, be made into electronic or manual Twoway valves, three-way valve or the like multichannel pipeline unlatching, close, the valve of switching effect.

Background technique

Chinese patent CN1254805A discloses a kind of " electrically controlled 4-way diverter valve ", and it has a valve cylinder body, and valve seat is arranged in the cylindrical shell, is connected with the plural mouth of pipe on the valve seat, and the valve piece that cooperates is with it arranged on the valve seat, and the valve piece then is subjected to the control of solenoid pilot valve.It by solenoid pilot valve electric and dead electricity, and utilize the pressure reduction of two-way high pressure in the refrigeration pipe system and low-pressure gas to push away movable valve block to move back and forth, thereby reach the high pressure that switches in four pipelines and the purpose of low-pressure gas flow direction.Because the processing technology complexity of this valve, many with material, cost is high, thereby price is expensive.But at present in world's refrigerating and air conditioning industry, this a kind of four-way valve only, the user is left with no alternative.

Summary of the invention

The problem that the utility model need solve is, overcomes disadvantages of background technology, provides a kind of reasonable in design, can guarantee sealing, processes the mortor operated valve simple, few with material again, that price is low.

Selector valve of the present utility model has a valve cylinder body, valve seat is arranged in the cylindrical shell, be connected with four pipes on the valve seat, the electrically-controlled valve piece that cooperates is with it arranged on the valve seat, it is characterized in that described valve piece is the rotary valve piece that can rotate in the plane, the rotating shaft on valve piece top cooperates with the axis hole that drum shaft puts, and between valve piece and the axle sleeve stage clip is arranged, valve piece bottom has can comprise and connect pipe, two cavities independent of each other, and described electric-controlled parts is motor and driving mechanism.Adopt plane rotation switching principle, changing the valve body translation is innovation main points of the present utility model for the plane turn.Motor and driving mechanism are that those skilled in the art can be finished.

Can be direct interlock between motor and driving mechanism and the rotary valve piece, also can be that the mode by mechanical transmission mechanism connects.

The design of four pipes has two kinds of schemes, or all is located on the valve seat, or establishes one on the valve cylinder, establishes three on the valve seat.Each can comprise two pipes two cavities of the former valve piece, and its shape can be two first quarter moon shape (see figure 3)s, also can be that eyes are specular; The sectional area of passage should be enough big, to guarantee the flow of fluid.The valve piece by 90 ° of-90 ° of rotations be a circulation (can be per 90 ° rotate continuously, also can per 90 ° of clockwise and anticlockwise alternately).There is aperture to be communicated with on one of them pipe (high pressure inlet pipe), so that the rotary valve piece is subjected to high pressure to strengthen sealing between it and the valve seat with valve pocket.Two cavities of latter's valve piece can comprise one and two pipes respectively, have passage and be communicated with valve pocket in the cavity that comprises a pipe, and the valve piece is a circulation by-120 ° of-+120 ° of rotations.

Motor and driving mechanism both can integral installation in the valve cylinder body, it is external also can be installed in valve cylinder, the stator and the rotor of motor can also be installed separately; The rotor portion of motor is installed in the valve cylinder body, and it is external that the stationary part of motor is installed in valve cylinder, is more convenient for making the valve cylinder body to do to such an extent that seal fully like this.

The utlity model has reasonable in designly, process the advantage simple, few, that price is low with material.

Embodiment

Below in conjunction with accompanying drawing the utility model is further described.

Embodiment 1, sees Fig. 1.This routine selector valve has a valve cylinder body 5, and cylindrical shell top has built-in motor and driving mechanism 1 to be connected with valve piece 2, is connected with four pipes (see figure 2) that becomes just distributing on the valve seat 3, and wherein D1 is the low pipe that extrudes, and D3 is high pressure inlet pipe, has aperture 9 to be communicated with valve pocket 7 on it.The rotating shaft 2-1 on rotary valve piece 2 tops cooperates with axis hole on the valve cylinder body 5 axle sleeve 5-1, and stage clip 6 is arranged between valve piece and the axle sleeve.Each becomes two first quarter moon shapes two cavities of valve piece 2 bottoms, and each cavity comprises two pipes.The valve piece is a circulation by 90 ° of-90 ° of rotations.

Fig. 3 is first state of rotary valve piece 2, and this moment, D2 was communicated with by cavity 2-1a with D3, and D2 becomes high blow-off pipe, and D4 is comprised and is communicated with by cavity 2-1b with D1, and D4 becomes the low pressure inlet pipe.Rotary valve piece 2 turns over 90 ° in the direction of the clock during electrical power, and stops at desired second state.This moment, valve piece cavity 2-1b was communicated with D1 and D2, and D2 switches to the low pressure inlet pipe by high blow-off pipe; Cavity 2-1a then is communicated with D3 and D4, and D4 switches to high blow-off pipe by the low pressure inlet pipe.Finish handoff procedure thus one time, the valve piece changes 90 ° again and is returned to first state when switching next time, finishes a circulation.

Embodiment 2, see Fig. 4.A high pressure inlet pipe D3 is arranged on the valve cylinder body 5 of this routine mortor operated valve, be connected with three pipes (see figure 5) that becomes just distributing on the valve seat 3, wherein D1 is low blow-off pipe.Cavity on the rotary valve piece 2 becomes two of sizes fan-shaped, and passage 8 is opened in little fan-shaped cavity top.First state is seen Fig. 6, and high pressure inlet pipe D3 is communicated with D2 by valve pocket 7, passage 8, little fan-shaped cavity 2-1a, and D2 is high blow-off pipe; Big fan-shaped cavity 2-1b is communicated with D1 and D4, and D4 becomes the low pressure inlet pipe.During electrical power, rotary valve piece 2 turns over 120 ° in the direction of the clock, and stops at desired second state.This moment, high pressure inlet pipe D3 was communicated with the D4 that little fan-shaped cavity 2-1a comprises, and D4 is switched into high blow-off pipe, and big fan-shaped cavity 2-1b then is communicated with D1 and D2, and D2 is switched into the low pressure inlet pipe.Finish handoff procedure thus one time, the revolution of valve piece is returned to first state for 120 ° when switching next time, finishes a circulation.This example adopts stepper motor external, and driving mechanism is built-in, and all the other are with embodiment 1.

If in this four-way mortor operated valve, cancellation D3 pipe, this valve promptly becomes the electric three-way valve.This moment, the D1 pipe was fluid inlet tube, and D2 and D4 are that fluid goes out pipe.When primary importance, D1 communicates with D4, and D1 is a fluid inlet tube, and D4 is that fluid goes out pipe, and D2 is a closed condition.When electric T-shaped valve get electric after, rotary valve 2 rotates, dead electricity when arriving desired location, rotary valve 2 stops at second state, this moment, D1 still be a fluid inlet tube, but the D4 pipe is closed, the D2 pipe is unlocked, the D2 pipe becomes fluid and goes out to manage.When valve once more after the electric and dead electricity, rotary valve 2 is with regard to reverse rotation or be rotated further first state.Continuous like this electric, dead electricity, again electric, dead electricity again, finish thus reach the D1 pipe fluid to the switching of D2 or D4 pipe conveyance fluid or the purpose of closing and opening.
