The design concept completely breaks the conventional design concept in a way that a firm and durable metal plate body is additionally arranged in the structure, the through hole is arranged on the plate body to be convenient for users to insert key rings or hang strings, the metal plate body is provided with good wear resistance and pressure resistance, thus the service life of the product can be effectively prolonged, and the wastage degree of the product is reduced, the casing body of the product is divided into an upper casing body and a lower casing body which adopt the design of a symmetric structure, when the combination is finished, a thin cavity body is formed at the inner parts of the upper casing body and the lower casing body, and the thin cavity body can be used for positioning a wireless radio frequency circuit board. The utility model has the advantages that the integral design concept of the product is ingenious, the design structure is reasonable, both the firmness and the sealing property are good, and the good practicability is provided, thereby being convenient for popularization and application.
Description
Technical field:
The utility model relates to the technical field of pneumatics, refrigeration, air-conditioning equipment, a kind of specifically cold medium compressor solenoid valve of control energy adjustment, the particularly mechanical connecting structure of its oil circuit switching mechanism.
Background technique:
Oil circuit switching mechanism in the general solenoid valve adopts piston, traveller or slide block as the commutation component that slide, and its geometrical shape is comparatively complicated, and the part processing difficulty is big.
So still need the oil circuit switching mechanism in the existing solenoid valve is further improved, effectively reduce its part processing difficulty, simplify product structure.
Summary of the invention:
The purpose of this utility model is to provide a kind of oil circuit switching mechanism that is used for solenoid valve, the structural type that it adopts thimble and steel ball to match, utilize steel ball to move back and forth to close or open the valve port at passage two ends that oil circuit is switched, the used component of this mechanism are few, simple in structure, Miniaturized, overcome the shortcoming and defect that prior art exists.
To achieve these goals, technological scheme of the present invention is: a kind of oil circuit switching mechanism that is used for solenoid valve, it mainly comprises valve body, it is characterized in that: be provided with the valve port seat in the described valve body, be provided with through hole in the last valve port seat, be provided with thimble in the through hole, be provided with the gap between last valve port seat and the valve body, be provided with steel ball in the gap.
The utility model discloses a kind of oil circuit switching mechanism that is used for solenoid valve, its mentality of designing design concept that breaks traditions fully, structurally added robust metal plate, and on plate body, offered perforation, be convenient to the user and wear key-ring or lanyard thereon, the plate body of metal has good wear-resisting crushing resistance, can effectively prolong the working life of product, reduced the extent of deterioration of product, the housing of product is divided into upper shell and lower shell body, and they become symmetrical structural design, when combination is finished, its inner thin type cavity that forms can be used for placing the wireless radio frequency circuit plate, and the product whole design idea is ingenious, project organization is reasonable, soundness and sealing are good, have good practicability, and be easy to utilize.

Embodiment:
With reference to the accompanying drawings, the utility model further is described
The utility model is a kind of oil circuit switching mechanism that is used for solenoid valve, it mainly comprises valve body 1, it is different from prior art and is: be provided with valve port seat 2 in the described valve body 1, be provided with through hole in the last valve port seat 2, be provided with thimble 3 in the through hole, be provided with the gap between last valve port seat 2 and the valve body 1, be provided with steel ball 4 in the gap, steel ball 4 is placed over against thimble, and described through hole is positioned at valve port seat 2 centre bits, be provided with thimble 3 in the through hole, 3 one-tenth " T " font structures of described thimble.
This oil circuit switching mechanism mainly contains 4 parts: valve body, last valve port seat, thimble, steel ball, because steel ball has substituted piston, traveller or slide block commutation slip component in the general solenoid valve, make whole oil circuit switching mechanism more terse, steel ball is a standard piece, the precision height, can directly purchase from the market, reduced the amount of finish of part, the corresponding cost of production that reduced, because the geometric accuracy of steel ball itself and dimensional accuracy guarantee, thereby have improved the operational safety of the assembly quality and the product of product.
The performance characteristic of oil circuit switching mechanism is as follows:
When the electromagnetic coil no electric circuit, steel ball has sealed lower valve port under the roof pressure of thimble, the high-pressure mouth medium can not be imported, then common port communicates with low pressure port, see shown in Fig. 3, after the electromagnetic coil energising, under the effect of electromagnetic force, the thimble parts rise, thimble unclamps steel ball, steel ball moves up under the holder power of the pressure medium of high-pressure mouth input, opens the lower valve port sealing automatically and goes up valve port, and this moment, high-pressure mouth communicated with common port, see shown in Fig. 4, again when after the electromagnetic coil outage then after, the thimble parts move down under the effect of spring force, thimble is pushed steel ball to lower valve port again, close lower valve port common port is communicated with low pressure port, so this oil circuit switching construction under the effect of electromagnetic force and spring force, can constantly switch oil circuit.
