Abstract
The utility model relates to a leakless valve for refrigeration air conditioning equipment, which is characterized in that the utility model comprises a motor, a coupling, an outer magnetic yoke, an outer magnetic body, an isolating shield, an internal magnetic body, an threading nut, a valve rod, a valve flap and a valve body, wherein, the valve body is provided inside with the valve flap; the valve flap is connected with the valve rod; the upper part of the valve rod is provided with the threading nut and the internal magnetic body; the isolating shield encloses the internal magnetic body and the valve rod inside; the outer magnetic yoke and the outer magnetic body are arranged outside the isolating shield corresponding to the internal magnetic body; the motor can drive the outer magnetic body to rotate through the coupling to make the internal magnetic body rotate accordingly under the magnetic force; thereby, the valve flap can open and close. The utility model has the advantage of a simple structure, which can completely solve the sealing problem in cooling air conditioning equipment with safety and reliability, and is not easy to be damaged, and brings great convenience to users.
Description
The utility model relates to a kind of valve, especially for the valve of refrigeration air-conditioner sealed pipe line traffic control.
Along with the develop rapidly of China's economic construction, the improving constantly of living standards of the people, refrigeration and air-conditioning technical has obtained using widely in every field such as industry, agricultural, commerce, food, medicine, building, national defence and high-tech.The valve that is used for the refrigerant pipe line traffic control of refrigeration air-conditioner at present mostly adopts the valve of conventional construction.Because its structural reason makes valve rod and valve body have the slipper seal point.Which type of sealing material all fundamentally not solve the sealing problem of refrigeration agent with.If the sealing failure will cause the leakage of refrigeration agent to make refrigerated air-conditioning system malfunctioning, and cause the pollution of environment, particularly the pipeline sealing problem of at present more advanced lithium-bromide absorption-type refrigerating machine is more outstanding, lithium bromide has very strong corrosivity, the sealing material that is suitable for is few, and the life-span is short, makes refrigeration air-conditioner often break down.
The purpose of this utility model is exactly the kind of drive of radical change conventional valves on the structure, makes the nonslipping seal point of valve, fundamentally solves the leakage problem of conventional construction valve with the mode of magnetic transmission.
The purpose of this utility model realizes by following technical proposals.The valve that is used for refrigeration air-conditioner of the present utility model comprises motor (manually handwheel), outer yoke, outer magnet, shielding can, inner magnet, screw, valve rod, flap and valve body; Be equipped with flap in the valve body, this flap connects valve rod, is equipped with on valve rod top that inner magnet, shielding can are installed on the valve body and with inner magnet and valve rod encapsulation within it.Outside and the corresponding position that above-mentioned motor (manually handwheel) can be sleeved on shielding can is provided with outer yoke and outer magnet.
The working condition of above-mentioned valve is such, when valve need be opened or close, only need to pass through magnetic drives by rotation (rotation of the handwheel) outer magnet of motor and the inner magnet on the corresponding shielding can inner valve stem, the corresponding rotation of inner magnet, drive screw, make valve rod move up and down, so that flap is opened in valve body or closed.Because the dynamic sealing point that do not leak outside of this valve, thereby thoroughly stopped the leakage problem of valve.
The utility model has the advantages that simple in structurely, solved the sealing problem of the pipeline control of refrigeration air-conditioner, safe and reliable, and also not fragile, brought many convenience to the user.
Further describe the structure that model utility is used for the valve of refrigeration air-conditioner below in conjunction with accompanying drawing, wherein:
Fig. 1 is used for the structural representation of refrigeration air-conditioner valve for the utility model.
Now referring to accompanying drawing, the valve that the utility model is used for refrigeration air-conditioner comprises valve body 1, flap 2, valve rod 3, screw 4, inner magnet 5, shielding can 6, shaft joint 7, motor (handwheel) 8, outer yoke 9, outer magnet 10.
Wherein be furnished with flap 2 in the valve body 1, connect valve rod 3, be mounted with on the top of valve rod 3 that screw 4 is connected with inner magnet 5 that shielding can 6 is installed on the valve body 1 and with inner magnet 5 and valve rod 3 encapsulation within it, motor 8 is by shaft joint 7 fixedly outer yoke 9 and outer magnet 10 and be sleeved on shielding can 6 relevant position outward.
Should know clearly that for a person skilled in the art, any improvement of having done on this basis can not break away from the application's spirit.
