Description
Technical field
The utility model relates to a kind of valve, specifically a kind of apparatus of air conditioning four-way change-over valve.
Background technique
The four-way change-over valve of the current apparatus of air conditioning forms primarily of four-way air operated reversing valve (main valve), solenoid directional control valve (control valve) and capillary tube.Form movable valve plug by slide block, piston in main valve, valve body of main valve two ends have through hole that the capillary tube at two ends can be made to be connected with valve intracorporeal space, and slide block two ends are fixed with piston respectively, and the space on piston both sides communicates by the exhaust port on piston.Control valve is made up of valve body and electromagnetic coil.Needle-like spool is had in valve body.There are three (or four) capillary tubies to be connected between main valve with control valve, form the entirety of four-way change-over valve.The four-way change-over valve not only complex structure of this kind of structure, and often easily there is the technical problems such as blocking in capillary tube.Although also having four way ball valve structure at present for four-way change-over valve there is not the technical problems such as blocking in it, but its four passage flow duct of traditional ball-valve structure controls to be two, and vertically crossing runner switching is through, and the four-way change-over valve of the apparatus of air conditioning must be four runner interfaces is all through, and these four runners can change runner direction according to valve element position, the ball valve of conventional construction grosses incompetence thus.How to simplify the technical pattern of four-way change-over valve, prevent the technical problems such as stuck, gas blowby, blocking is the object that those skilled in the art study always.
Summary of the invention
The utility model provides the apparatus of air conditioning four-way change-over valve that a kind of structure is simple, long service life, technical failure are few.
A kind of apparatus of air conditioning four-way change-over valve, comprise four-way change valve and spool, surrounding valve body is connected to suction tude, the first arm, outlet pipe, the second arm that spool pilot line is communicated with, be respectively equipped with corner between described suction tude and the first arm, the second arm, between outlet pipe and the first arm, the second arm, be respectively equipped with corner; Described spool comprises the cylindrical body of upper and lower two proportioning valve intracoelomic cavities, is provided with point chamber muscle of one between two cylindrical bodys; Described spool is driven by reducing motor and rotates.This kind of apparatus of air conditioning four-way change-over valve is by arranging corner between suction tude and the first arm, the second arm, arrange corner between outlet pipe and the first arm, the second arm, that is a kind of preferred structure is that around valve body periphery, 90 degree of angles are arranged successively for suction tude, the first arm, outlet pipe, the second arm.Thus under point chamber muscle effect of spool, valve body is divided into two chambers, a chamber suction tude and the first arm, another chamber outlet pipe and the second arm, after spool rotates under reducing motor drives, valve body is realized to be divided into two other chamber, a chamber suction tude and the second arm, another chamber outlet pipe and the first arm, thus under the state not changing suction tude and steam outlet pipe, realize the switching of four-way change-over valve, namely the apparatus of air conditioning freezes or heats the switching of two states.It should be noted that suction tude, its effect of outlet pipe are constant all the time in apparatus of air conditioning four-way change-over valve at this, namely suction tude enters pressurized gas all the time, and low-pressure gas arranged all the time by outlet pipe, difference is that pressurized gas flow to the refrigeration or heat-production functions that determine.The four way ball valve of conventional construction does not have above-mentioned functions, and the application also not possessing this respect may.
Two cylindrical body exterior edge faces on described spool are connected to front-end bearing pedestal and rear bearing block, front-end bearing pedestal and rear bearing block are connected to bearing, two bearings connect front cover and the rear end cover of sealed valve body respectively, and before and after being formed, the supporting structure of duplex bearing prevents spool owing to frequently rotating the technical failure such as stuck caused.
Described center, front-end bearing pedestal outer end is provided with mounting hole, the output shaft of the reducing motor that is connected in mounting hole; Two cylindrical bodys on described output shaft and spool are coaxially arranged, by coaxially arrange increase by two cylindrical bodys in rotary course with the performance that is sealed and matched of body cavity, prevent the product rejection problem that gas blowby causes.
Two cylindrical body exterior edge faces on described spool are respectively equipped with location shrinkage pool, location shrinkage pool coordinates front-end bearing pedestal and the rear bearing block of embedding respectively, location shrinkage pool is by screw equally distributed on bottom surface, bolton connects front-end bearing pedestal and rear bearing block, increases spool, the close-fitting installed between front-end bearing pedestal and rear bearing block and installation efficiency.
The utility model is by the cylindrical body of upper and lower two proportioning valve intracoelomic cavities, point chamber muscle structure of one is provided with between two cylindrical bodys, under the driving of reducing motor, change suction tude be communicated with situation with between the first arm or the second arm, and outlet pipe is communicated with situation with between the first arm, the second arm, realize the switching that the apparatus of air conditioning freezes or heats two states, change the technical problem existed in conventional construction.
Accompanying drawing explanation
Be illustrated in figure 1 the utility model apparatus of air conditioning four-way change-over valve master and look sectional structure schematic diagram;
