Definitions
- the present invention relates to a pipe connection structure that connects pipes by connecting flanges.
- a vehicle air conditioner performs heat exchange between indoor air and an evaporator by circulating a refrigerant.
- the refrigerant adiabatically expanded through an expansion valve is in a two-phase state of gas and liquid. As it enters the evaporator, it absorbs heat from the outside and evaporates (evaporates) to continue isothermal expansion to cool the air in the cabin. Then, it becomes superheated steam and is sucked into the compressor.
- a pipe connection structure is provided in a portion of the evaporator.
- a conventional pipe connection structure is configured as described in Japanese Patent Application Laid-Open No. 7-329549.
- a pipe block in which the end of the supply pipe for supplying and outflow of the refrigerant and the end of the outflow pipe are connected to the evaporator via an expansion valve, and a bolt is connected to the bottom of the pipe block. After passing through the through hole and the insertion hole of the expansion valve, it is screwed into the female screw portion formed in the evaporator.
- FIGS. 1A, 1B, and 1C Piping connection structures similar to such a configuration are shown in FIGS. 1A, 1B, and 1C.
- the flange 3 connecting the end of the supply pipe 1 and the end of the outflow pipe 2 is connected via two bolts 4 passing through the mounting holes 3a of the flange 3. It is screwed into the female thread 6a of the flange 6 integral with the evaporator 5.
- an object of the present invention is to provide a piping connection structure that solves the above-mentioned problems.
- the present invention relates to a first flange having a plurality of one flow paths, the first flange having a female screw portion, and a plurality of pipes having the other flow path formed.
- a second flange having a groove formed on the outer peripheral surface thereof along the thickness direction, and a second flange being fitted into the groove from the outer peripheral surface of the second flange, and being screwed into the female thread portion of the first flange.
- a bolt for connecting the first flange and the second flange by inserting the first flange and the second flange.
- the bolt when the first flange and the second flange are connected, the bolt is inserted into the groove from the outer peripheral surface of the second flange, and then screwed into the female screw portion of the first flange. Since there is no need to push the bolt in the axial direction and pass it through the second flange, the bolt can be easily installed without the need for a hand to enter between the pipes.
- one of a concave portion and a convex portion in which the one flow path is opened is formed on a mating surface of the first flange, and the mating surface of the second flange is formed.
- the convex portion is fitted into the concave portion, and a sealing material is interposed between the outer peripheral surface of the convex portion and the inner peripheral surface of the concave portion. You may do it.
- FIG. 1A is a plan view of a conventional pipe connection structure.
- FIG. 1B is a front view of a conventional pipe connection structure.
- FIG. 1C is a right side view of a conventional pipe connection structure.
- FIG. 2 is an explanatory view of an operation of a conventional pipe connection structure.
- FIG. 3A is an enlarged view of a main part of Embodiment 1 of a pipe connection structure according to the present invention.
- FIG. 3B is a front view of the flange of the pipe connection structure according to the first embodiment of the present invention. is there.
- FIG. 4 is an operation explanatory view of Embodiment 1 of the piping connection structure according to the present invention.
- FIG. 5 is a front view of a flange according to a second embodiment of the pipe connection structure according to the present invention.
- FIG. 6 is a plan view of a main part of a third embodiment of the pipe connection structure according to the present invention.
- Embodiment 1 is shown in FIGS. 3A, 3B, and 4.
- FIG. 4 the evaporator 5 is provided with a flange (first flange) 6, and the flange 6 has two flow paths (not shown) formed therein. It is connected to.
- a flange (second flange) 3 for coupling with the flange 6 is provided.
- An end of the supply pipe 1 and an end of the outflow pipe 2 for forming the flow paths la and 2a are connected to the flange 3. That is, the end of the supply pipe 1 and the end of the outflow pipe 2 are fitted into the through holes 3d and 3e of the flange 3 shown in FIG. 3B.
- a groove 3b is formed instead of a mounting hole for passing the bolt 4 through.
- the groove 3 b is formed on the outer peripheral surface 3 c on both sides of the flange 3 along the thickness direction of the flange 3.
- the groove 3b is formed obliquely with respect to the upper and lower surfaces of the flange 3.
- Bolts 4 fitted in these grooves 3b are screwed into female screw portions 6a formed in the force flanges 6.
- a flat washer 7 is provided between the head of the bolt 4 and the flange 3 so as to pass through the bolt 4.
- a pair of flow paths (not shown) is formed in the flange 6, and a projection 6f in which one of the pair of flow paths is opened is formed on the joint surface of the flange 6.
- a concave portion 3h into which the convex portion 6f is fitted is formed on the joint surface of the flange 3.
- the recess 3h is formed up to the position of the end face of the supply pipe 1 in a state where the end of the supply pipe 1 is fitted into the through hole 3d of the flange 3.
- a circumferential groove is formed on the outer peripheral surface of the projection 6f, and an O-ring 8c as a sealing material is fitted into the circumferential groove.
- FIG. 3 differs from the first embodiment only in the shape of the groove 3b formed in the flange 3.
- groove 3b is formed substantially at right angles to outer peripheral surface 3c.
- FIG. 1 a third embodiment is shown in FIG.
- the joint surface force of the flange 3 also protrudes.
- the channels la and 2a are opened in the sections 3f and 3g.
- channels 6 b and 6 c are formed in the flange 6, and concave portions 6 d and 6 e in which the channels 6 b and 6 c open are formed on the joint surface with the flange 3.
- a circumferential groove is formed on the outer peripheral surface of each of the projections 3f and 3g, and O-rings 8a and 8b serving as seal materials are fitted into the circumferential grooves.
- the O-rings 8a, 8b hermetically seal the gap between the outer peripheral surfaces of the convex portions 3f, 3g and the inner peripheral surfaces of the concave portions 6d, 6e, so that the flow paths 6b, 6c and Communication with la and 2a can be performed in an airtight manner.
- the bolt when connecting the first flange and the second flange, the bolt is fitted into the outer peripheral surface force groove of the second flange, and then screwed into the female screw portion of the first flange. Since it is not necessary to push the bolt in the axial direction and pass it through the second flange, the bolt can be easily attached even if the hand does not enter between the pipes.
