The utility model has the advantages of compact design, small size, and low cost. The utility model can also facilitate mass production, improve the performances of the electronic expansion valve effectively, and make the work process more reliable and efficient.
Description
[technical field]
The utility model belongs to the valve arrangement technical field, particularly relates to a kind of valve body structure of electric expansion valve.
[background technique]
The refrigerant flow control is to adopt capillary tube and heating power expansion valve in the present domestic refrigerated air-conditioning system, but application along with converter technique, the flow adjustment range of system, speed, precision etc. are required to improve greatly, work under the best circumstances, begin to adopt comparatively advanced electric expansion valve now for making system, and the electric expansion valve ubiquity that uses at present complex structure, bulky, it is unreliable to move, and manufacturability is poor, the cost height, defectives such as processed complex.
[model utility content]
The technical assignment of the technical problems to be solved in the utility model and proposition is to overcome the technological deficiency that existing product exists, and provides a kind of compact structure, reliability height, electric expansion valve valve body structure easy to process, with low cost.
The technological scheme that the utility model is taked is: the electric expansion valve valve body structure, comprise case, be located at rotor part and stop dog part in the case, the valve seat and the valve port of case below is characterized in that described valve port is one to have the pipe fitting of through hole, its inwall upper end is the guiding cylinder, the neutral position is provided with internal thread, and the lower end forms chamber, and the plane of described chamber is provided with the valve port hole, its sidewall is provided with aperture, and the lower end and the sidewall of described valve seat are equipped with opening.In the working procedure, produce magnetic field, the motion of control rotor part, the opening, stop of the rotor part that cooperates with it by stop dog part control by the outer coil that is provided with of case.The guiding cylinder that is provided with in the valve port plays the effect of setting upright rotor part, and internal thread can guide the needle rotation work, and two openings on the valve seat all are connected with adapter, guide the flow direction of fluid in use.This structure has been saved transmission nut, by internal thread is set in valve port, valve port is made of one the formula structure, makes its structure more succinct, and working procedure is more leaned on.
Described valve port is positioned at valve seat, with valve seat lower ending opening place inwall close-fitting, and connects by soldering.This structure is saved nut, adopts to be press-fitted valve port earlier, and the back processes valve port hole, guiding cylinder, internal thread, has guaranteed the coaxality of valve port, with valve port and valve seat fixed connection, makes the valve needle movements stroke definite relatively by soldering, has improved the performance of this electronic valve.
Aperture on the described chamber sidewall communicates with valve base cavity, and its aperture position and valve seat sidewall opening are at an angle.This setting makes aperture and takes over mouthful position (promptly not in one direction) at an angle, has avoided fluid directly to impact needle, and has influenced the service behaviour and the working life of valve.
Described case, valve seat are formed by stainless steel stretched, connect by argon arc welding or plasma welding between them.This structure is with case and valve seat finally sealed, and heating is few, can effectively reduce the heat affecting to magnet rotor, improves the precision and the working life of electric expansion valve.
The utility model is compared with existing valve body and had the following advantages: 1, compact structure, volume is little, and is reliable.2, this structure is except that valve port is the Vehicle Processing part, and all the other are stamping part, so high conformity, helps generation in enormous quantities.3, the valve port integral structure improves the electronic valve service behaviour, and assembling is simple, effectively reduces cost.
