Embodiment
Below in conjunction with accompanying drawing, specify mode of execution of the present invention.
First mode of execution:
Please with reference to Fig. 1, Fig. 2, Fig. 1 is the structural representation of direct-acting type two-way solenoid valve first mode of execution of the present invention, and Fig. 2 is that the A-A of Fig. 1 is to sectional view.
Direct-acting type two-way solenoid valve comprise valve component 2, with valve component 2 coil component 1 through screw; Valve component 2 comprises that first takes over the valve seat 21 that 22a, second takes over 22b and is communicated with respectively with both; Be symmetrically arranged with a pair of valve port 21a 1,21b 1 on the valve seat 21, valve port 21a 1/21b 1 takes over 22a and second and takes over 22b and be connected with first respectively.Valve seat 21 machined are hollow shape, are formed with to have step-like valve pocket 26.In direction illustrated in figures 1 and 2, valve seat 21 internal upper part cavitys are cylindric, and the external diameter of its internal diameter and sleeve pipe 23 is complementary, and both are fixing through welding; The inwall of its underpart cavity is formed by the plane 211a/212a and the arc surface 213a/214a encirclement of symmetry, and two plane 211a/212a are parallel to each other, and spacing between the two forms stepped part less than the internal diameter of upper chamber.
The end sealing and fixing away from valve seat 21 at sleeve pipe 23 has static iron core 24; In the inner chambers that sleeve pipe 23 and valve component 2 form jointly, iron core 27 is arranged, between moving iron core 27 and static iron core 24, be provided with returning spring 25.The external diameter of moving iron core 27 and the internal diameter of sleeve pipe 23 are complementary, and can in sleeve pipe 23, slide up and down.Moving iron core 232 is provided with minor diameter part 271 near valve port one end, and in this mode of execution, minor diameter part 271 is integrative-structure with moving iron core 27 integral body, can carry out cutting through the end to moving iron core 27 and form.Certainly minor diameter part 271 also can be made separately, and is fixing through welding with moving iron core 27 then.Minor diameter part 271 forms stepped part with moving iron core 27, and formed stepped part cooperatively interacts in this stepped part and the valve base cavity.In this mode of execution; The length of the path section 271 of moving iron core 27 ends is set to; When moving iron core 27 moved downward limit position, its end face was lower than valve port 21a1/21b1, made the sealed member that is arranged on the path section 271 can valve port 21a1/21b1 be sealed.In addition, moving iron core 27 also is provided with an axial through hole 272, and through hole 2381 is connected with valve pocket 26.
The path section 271 of moving iron core 27 has been disposed radially through hole, through hole be built-in with a pair of sealing plug 28b.Sealing plug 28a/28b cross section is T-shaped, and its bigger diameter end end face is the plane, matches with the inwall plane 211a/212a of valve pocket 26 respectively.Between sealing plug 28a and the 28b, be provided with support spring 29, under the effect of spring force, the bigger diameter end of sealing plug 28a and 28b all is pressed on the opening of valve port 21a1/21b1, and it is sealed.
Need to prove that the nouns of locality such as " top, belows " of indication all is to Figure of description in the description of above mode of execution, in fact is not limited thereto.
When the electromagnetic coil no electric circuit; Moving iron core 27 moves down under the effect of returning spring 25, drives the sealing plug 28a/28b that is arranged on minor diameter part 271 and moves down together, and be pressed on the opening portion of valve port 21al/21bl; Valve port is closed; At this moment, refrigerant no matter is from the first adapter 22a or taking over 22b from second gets into, and solenoid valve all is in closed condition.
When electromagnetic coil is switched on; Electromagnetic force overcomes the active force of returning spring 25 and the frictional force between sealing plug 28a/28b and the valve port 21a1/21b1, make on the iron core 27 and move, until with static iron core 24 adhesives; At this moment; The sealed member that is arranged at path section 271 also with on move, valve port 21a1/21b1 opens, solenoid valve is opened.
Second mode of execution:
Second mode of execution is that the locality of on the basis of first mode of execution, being done changes; Be mainly reflected in the structural design of moving iron core member path section; This mode of execution is that with the difference of first mode of execution when coil component 1 no electric circuit, solenoid valve is in opening state; When coil component 1 energising, solenoid valve is in closed condition.
Introduce the structure of this mode of execution below in conjunction with accompanying drawing, the parts for identical with effect with the first mode of execution structure adopt same numbering to describe.
Please with reference to Fig. 3, Fig. 3 is the structural representation of direct-acting type two-way solenoid valve second mode of execution of the present invention.In this mode of execution, the radial direction through hole top that path section 271 is offered also offers fluid passage 273.When moving iron core 27 was displaced downwardly to limit position, fluid passage 273 was communicated with valve port 21a1/21b1.At this moment, sealed member is for the positional structure of first mode of execution, more near the bottom of valve pocket 26.
The structural design of this mode of execution remaining part is identical with first mode of execution, gives unnecessary details no longer one by one at this.
When coil component 1 no electric circuit, moving iron core 27 moves down under the effect of returning spring 25, drives the sealing plug 28a/28b that is arranged on minor diameter part 271 and moves down together, and entire body passage 273 is connected with valve port 21a1/21b1, and at this moment, valve port 21a1/21b1 is in opening state.
When coil component 1 energising, electromagnetic force overcomes the active force of returning spring 25, makes on the iron core 27 to move; Until with static iron core 24 adhesives; The sealed member that is arranged at path section 271 also with on move, until the opening portion that is pressed on valve port 21a1/21b1,21a1/21b1 closes with valve port.At this moment, refrigerant no matter is from the first adapter 22a or taking over 22b from second gets into, and solenoid valve all is in closed condition.
At above two kinds of mode of executions, the latus rectum that is specially adapted to valve port is arranged on the bidirectional electromagnetic valve between the 0.5-2.5mm.
