Embodiment
To combine accompanying drawing that innovative idea of the present invention is further specified below.
The main valve of four-way reversing valve structural representation that Fig. 3 provides for the present invention, the schematic perspective view of one of preferred link assembly that Fig. 4 provides for the present invention.
Like Fig. 3 and shown in Figure 4.The main valve of selector valve comprises that valve component 200, valve component 200 are provided with the passage that a plurality of confession refrigeration streams switch.Two piston assemblys 300 about in valve component 200, being provided with have the attachment hole 11 of installation on the link assembly 100, piston assembly 300 is fixed on through screw 4 and installs on the attachment hole 11.Mangetic core assembly 400 is fixed on link assembly 100 and attendes on the cavity 24 of basic courses department.In the refrigeration system working procedure, the pressure change in two piston assemblys, 300 pairing cavitys disequilibrates when concerning, two piston assemblys 300 can drive mangetic core assembly 400 and move to switch flow path channel.
This link assembly 100 comprises con-rod only 2 and link 1.Its con-rod only 2 structures are that sheet material is through punching press and bending and molding; It comprises the rectangular-shaped basic courses department of smooth one-tenth 21 and from the bending part 22 of the bending that stretches out of the horizontal X-X symmetry of basic courses department 21; In basic courses department 21, be provided with cavity 24 through the punching mode; So that fixing and installation mangetic core assembly 400 is provided with the integral bending that bending part 22 helps to improve con-rod only 2, the simple cost of this processing mode is lower.
In the present embodiment, the width B 1 of opening slot 12 is slightly larger than the thickness B 2 of the basic courses department 21 of con-rod only 2; And the length H1 of opening slot 12 is slightly less than the width H2 of the basic courses department 21 of con-rod only 2; Its objective is when the end 23 of con-rod only 2 and embed in this opening slot 12; The matching gap of two links is little; And the link 1 through metal-cutting machining method moulding or the block structure that directly obtains through shaping material processing has higher intensity through sheet material through the con-rod only 2 of punching press and bending and molding, thus such fit system effectively control link body 2 at the axial distortion of Y-Y (M1).
The having two that two vertical Y-Y axisymmetric with respect to the basic courses department 21 of con-rod only 2 distribute towards con-rod only 2 opposite directions attachment holes 11 be installed of each link 1; And the axle line Z1/Z2 of the corresponding installation attachment hole 11 of two links passes the material layer of the basic courses department 21 of con-rod only 2; So about two piston assemblys 300 power of imposing on con-rod only 2 can not make con-rod only 2 the axial distortion M1 of horizontal X-X occur, make link assembly slide steadily.
The main valve of four-way reversing valve structure of said structure, the con-rod only 2 of its link assembly 100 has been cancelled the bending of both sides, end through the plate stamping brake forming, and structure is simpler than existing technology, is convenient to machine shaping; Coupling rod parts 1 is through the metal chip processing mode or directly obtain through section bar processing, and it is installed attachment hole 11 and can one-time positioning process simultaneously with opening slot 12, has guaranteed the precision of mutual alignment, positional accuracy that can control valve core assembly 400 after the installation.According to the intensity needs, coupling rod parts 1 can be selected Cu alloy material or steel etc. for use.
Fig. 6 is the shaping material structural representation that is used to process link.As shown in Figure 6, the link 1 preferred section bar processing method of using is bored attachment hole after shaping material cuts off and rivet hole gets final product, and is fit to large batch of production scale, lowers cost of production.
Two schematic perspective view of the preferred link assembly that Fig. 5 provides for the present invention.As shown in Figure 5.Present embodiment and aforementioned schemes difference are; Con-rod only 2A comprises the basic courses department 21 that is roughly rectangle and extends the bending part 22 of bending from basic courses department's 21 horizontal directions; Link 1 is roughly the block structure through metal cutting method or section bar processing, and link 1 has the attachment hole 11 of installation towards the opposite direction of con-rod only 2; Be provided with stepped part 13 at link 1 towards an end of con-rod only 2, the end 23 of con-rod only 2 places on the stepped part 13, can link 1 be fixed on the two ends of con-rod only 2 through welding manner.Because effect that present embodiment played and implementation result and aforementioned schemes are basic identical, those skilled in the art should be understood that, repeats no more at this.
The stress of the present invention in having taken into full account the actual using process of the link assembly in the selector valve; With link is section bar machine shaping or cutting moulding; Con-rod only adopts sheet material processing; Make the weakness zone dividing processing strengthen design separately, weakness zone has been carried out improving design, intensity is improved significantly.Take into account simultaneously the manufacturability of materials processing again and improve, make the selector valve main valve be applied on the big specification four-way valve, have very high voltage endurance capability and operational safety.
The above only is a preferred implementation of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; Can also make some improvement and retouching, these improvement and retouching also should be regarded as protection scope of the present invention.
