Abstract
The utility model discloses a kind of electrically operated valve with instruction function, it is driving chamber above valve deck, motor is set in the driving chamber, gear one is set on the output shaft of motor, the gear one is engaged with gear two, gear two and gear three are coaxial, and gear three and gear four engage, and gear four is arranged on valve rod；The lower section of the valve deck is fixed with sealing shroud, and multiple grooves are arranged along the axial direction of valve rod in sealing shroud, and the outer diameter of sealing ring is embedded in the groove, and the internal diameter of sealing ring covers on the outside of the light bar segment of valve rod；Direction board is arranged in the part that the upper end of the valve rod passes through driving chamber.The utility model has the advantages that: since sealing ring is arranged in the groove of sealing shroud, do not moved with the axial movement of valve rod；And the sealing ring setting of multilayer can guarantee effectively sealing, it is often more important that, sealing ring is the position of polished rod for being sleeved on valve rod, is sleeved on threaded portion in this way, overcoming, and seals bad defect.
Description
Technical field
The utility model relates to valve gate technology, specifically a kind of electrically operated valve.
Background technique
Valve is different according to the occasion used, and the very inconvenient place of manual operation is arranged in sometimes, at this moment just needs
A kind of electronic valve, passes through the opening and closing of power supply control valve；Existing electrically operated valve generally uses helical structure control valve core
Opening and closing, and the greatest problem of helical structure is to seal more difficult, especially electrically operated valve, it is also necessary to by driving chamber and valve body
Separate from order to avoid damaged to motor.
Utility model content
In order to solve the above technical problems, valve body is isolated very well with driving chamber the purpose of the utility model is to provide a kind of
Electrically operated valve, specific technical solution are as follows:
A kind of electrically operated valve with instruction function, including valve body, described valve body one end connect water inlet pipe, and other end connects
Connected water outlet pipe, valve body are fixed with valve deck, and threaded hole is arranged among valve deck, and valve rod is screwed in the threaded hole, set below valve rod
Spool is set, the spool matches with the shape of through holes on bottom flange；It is characterized by: being driving chamber, institute above the valve deck
It states and motor is set in driving chamber, gear one is set on the output shaft of motor, the gear one is engaged with gear two, gear two and tooth
Wheel three is coaxial, and gear three and gear four engage, and gear four is arranged on valve rod；The number of teeth of the gear one is less than the tooth of gear two
Number, the number of teeth of gear three are less than the number of teeth of gear four；The lower section of the valve deck is fixed with sealing shroud, along the axis of valve rod in sealing shroud
To multiple grooves are arranged, the outer diameter of sealing ring is embedded in the groove, and the internal diameter of sealing ring covers on the outside of the light bar segment of valve rod；Institute
The upper end for stating valve rod passes through the part setting direction board of driving chamber.
Thread segment is set on the valve rod, and the diameter of the thread segment is greater than the diameter of light bar segment.
Water-in flange is arranged in the water inlet pipe, and water-output flange is arranged in the outlet pipe.
The utility model has the advantages that: since sealing ring is arranged in the groove of sealing shroud, not with the axial direction of valve rod
It moves and moves；And the sealing ring setting of multilayer can guarantee effectively sealing, it is often more important that, sealing ring is the light for being sleeved on valve rod
Bar position is sleeved on threaded portion in this way, overcoming, and seals bad defect.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is illustrated with reference to the accompanying drawing, as shown, the utility model includes valve body 1, the valve body 1
One end connects water inlet pipe 2, and other end connects outlet pipe 3, and valve body 1 and valve deck 4 are fixed, and threaded hole, valve rod is arranged among valve deck 4
Thread segment 51 is set on 5, and the diameter of the thread segment 51 is greater than the diameter of light bar segment 52；Thread segment 51 screws in the threaded hole
In, spool 17 is arranged in the lower section of valve rod, and the spool 17 matches with the shape of through holes on bottom flange 18 to guarantee to be opened and closed；It is described
It is driving chamber 6 above valve deck 4, motor 9 is set in the driving chamber 6, gear 1, the tooth are set on the output shaft of motor 9
It takes turns 1 to engage with gear 2 11, gear 2 11 and gear 3 12 are coaxial, and gear 3 12 and gear 4 13 engage, and gear 4 13 is set
It sets on valve rod 5；The number of teeth of the gear 1 is less than the number of teeth of gear 2 11, and the number of teeth of gear 3 12 is less than gear 4 13
The number of teeth；The lower section of the valve deck 4 and sealing shroud 7 are fixed, and multiple grooves 71, sealing ring 8 is arranged along the axial direction of valve rod in sealing shroud 7
Outer diameter be embedded in the groove 71, the internal diameter of sealing ring 8 covers in 52 outside of light bar segment of valve rod；It wears the upper end of the valve rod 5
Overdrive chamber 6 part setting direction board 14, with the rotation of valve rod, direction board is also accordingly rotated, therefore, can be from external observation
Whether spool is opened.
Water-in flange 15 is arranged in the water inlet pipe 2, and water-output flange 16 is arranged in the outlet pipe 3.
