[0046] Figure 5 It is a perspective view of a control valve PC2 as a second modification of the control valve. Such as Figure 5 As shown, for the control valve PC2, the two faces (two faces on the Z side) facing the bracket and the fixed plate are chamfered on the D face. Therefore, the shape of the bracket and the fixing plate are preferably also deformed according to the shape of the control valve PC2.
[0047] In addition, the portions corresponding to the pair of side walls of the bracket and the pair of side walls of the fixing plate are chamfered to form a groove portion TR2 and a step portion TR3 (a kind of groove portion). That is, the groove portion TR2 and the step portion TR3 are formed at the four corners of the cross-sectional direction (YZ plane) of the control valve PC2. like Figure 5 For the control valve PC2 shown, the four grooves TR2 on the +X side and Figure 4 Similarly, the groove portion TR1 shown has side surfaces on both sides in the X-axis direction,...

The invention provides a fixing structure of a control valve and a fixing method of the fixing structure of the control valve, and a fixing plate and a support of the fixing structure is strong in fixing strength. The control valve is fixed on a runner steering portion through the fixing structure (100) of the control valve. The fixing structure of the control valve comprises a bottom face (101), a first side wall (102a) and a support (10) of a second side wall (102b), wherein the bottom face is tightly fixed on the runner steering portion, and the first side wall and the second side wall extend to a control valve side from two end portions of the bottom face and are provided with an concave portion (104) which is formed by a pair of arms (103). The fixing structure of the control valve further comprises an upper face (111), a third side wall (112a), a fourth side wall (112b) and fixing plates (11) of two pairs of inserting holes (113), wherein the upper face is located on the side of the control valve, the third side face and the fourth side face extend to the side of the runner steering portion from two end portions of the upper face, and the inserting holes are formed in the third side wall, the fourth side wall and a connecting portion of the upper face. The front ends of the arms of the support are curved and fixed in the inserting holes of the fixing plates in a riveting mode.
Description
Technical field [0001] The present invention relates to a flow path reversing valve for reversing the flow path of a refrigerant for refrigeration, refrigeration, air conditioning, hot water supply cycle, and the like. Background technique [0002] Conventionally, there is a device disclosed in Patent Document 1 (CN201636376U) as a flow path switching valve (for example, a four-way valve) used in a refrigeration cycle. The flow path switching valve of Patent Document 1 switches the flow path of the fluid in the flow path switching section by means of a control valve. [0003] In Patent Document 1, a fixing structure for fixing the control valve to the flow passage reversing part is disclosed. That is, a structure is disclosed in which the arm of the bracket is fitted into the grooves formed at the four corners of the flat fixing plate, and the fixing plate is fixed to the bracket by bending the front end of the arm. [0004] However, since the fixing structure disclosed in Patent D...
