Abstract
The utility model relates to a cam electric guide valve which is composed of a valve body, a guide hole, a valve seat, a valve core, a gland, a valve closing spring, a press rod, a return spring, an O-shaped sealing ring, a cam, a miniature motor and a support of a motor. The utility model is used for controlling liquid conveying, especially for controlling tap water supply systems, and avoids various problems caused by vibration and interference of external magnetic fields when electromagnetic guide valves are used.
Description
The utility model relates to and is used for the pilot valve that liquid is carried control, and what have is also referred to as switch valve, more particularly relates to the electronic pilot valve of a kind of cammingly.
Generally speaking, being used for liquid carries the pilot valve or the switch valve of control to be the electromagnetic type pilot valve, its principle is forward and reverse drive spool and the switch spring by solenoid current, make the pilot valve opening and closing, make the spool self-locking with permanent magnet under off-position, this structure is shaken or the interference of external magnetic field and malfunctioning easily.
The purpose of this utility model provides a kind of electronic pilot valve of cammingly of switch flexibility and reliability.
The electronic pilot valve of cammingly of the present utility model, by valve body, pilot hole, valve seat, spool, gland, valve-closing spring, depression bar, Returnning spring, sealing O type circle, cam, miniature motor and electric machine support are formed, the outer wall that it is characterized in that valve seat is threaded with valve body and valve gap and is threaded, valve seat and valve body joint have sealing O type circle, gland plays fixation to electric machine support, and spool is had position-limiting action, prevents that spool from excessively moving up; Spool is the cylindric of band convex edge, places valve seat to move up and down, and valve-closing spring and depression bar are housed in the cylinder of spool, and the part that the gland outside is stretched out on the top of depression bar is hemisphere type, and end face contacts with eccentric outer rim; Be provided with Returnning spring in the gap of spool and valve seat, iron chains embedding one sealing O type circle in the groove of spool bottom.Used micromachine is the self-locking motor of band reducing gear, guarantees can oneself not rotate under vibrations or magnetic field situation at cam under cold situation.
The principle of the electronic pilot valve of cammingly is: miniature motor drives cam rotation, when the edge of cam semi major axis contacts with the hemispherical end face of depression bar, it is downward that depression bar compression valve-closing spring drives spool, and the caulking gum of installing on the spool blocks the pilot hole of valve body, and pilot valve is closed; When the edge of eccentric wheel short radius contacts with the hemispherical end face of depression bar, rely on the tension force of Returnning spring that spool is mentioned, pilot hole is opened, and pilot valve is on state.Along with the Electric Machine Control program of artificial setting, this pilot valve can be opened or close at any time.Because eccentric wheel and depression bar are rigid construction, and motor self-locking under off-position, can not shaken or external magnetic field disturbs, the switch flexibility and reliability.
The electronic pilot valve of cammingly of the present utility model is used for the conveying of liquid to be controlled in particular for tap water supply system, the variety of issue that has occurred when having avoided using the electromagnetic type pilot valve.
Describe the structure of the electronic pilot valve of the utility model cammingly in detail below in conjunction with accompanying drawing:

Claims (2)
1, the electronic pilot valve of a kind of cammingly, by valve body, pilot hole, valve seat, spool, gland, valve-closing spring, depression bar, Returnning spring, sealing O type circle, cam, miniature motor and electric machine support are formed, the outer wall that it is characterized in that valve seat is threaded with valve body and valve gap and is threaded, valve seat and valve body joint have sealing O type circle, gland plays fixation to electric machine support, and spool had position-limiting action, spool is the cylindric of band convex edge, place valve seat to move up and down, be equipped with in the cylinder of spool and close valve list spring and depression bar, the part that the gland outside is stretched out on the top of depression bar is hemisphere type, and end face contacts with eccentric outer rim; Be provided with Returnning spring in spool and the valve seat gap, iron chains embedding one sealing O type circle in the groove of spool bottom, miniature motor drives eccentric wheel and rotates, and spool is moved up and down, and causes the pilot hole of valve body to open or close, thus the break-make of control valve.
2, the electronic pilot valve of cammingly according to claim 1 is characterized in that described miniature motor is the self-locking motor of band reducing gear, guarantees can oneself not rotate under vibrations or magnetic field situation at cam under cold situation.
