Technical problem to be solved by the invention
In the assembly of the solenoid valve described above, the first pipe is fixedly attached to the valve main body by brazing, and the second pipe is fixedly attached to the seat member by brazing. Then, a suction element, a plunger, a valve body, and a valve opening spring are disposed inside the valve body. Thereafter, the seat member is fixedly attached to the valve main body by welding. Therefore, when the seat member is fixedly mounted in a misaligned state with respect to the valve body, the valve seat is also misaligned, and thus valve leakage may occur. Further, the valve seat cannot be adjusted after the seat member is fixedly attached to the valve main body. Therefore, the inventors of the present application have invented a structure in which a portion of the valve body where the valve body and the like are disposed is divided from the cover. In this configuration, after the seat member is fixedly attached to one end portion of the cylindrical valve main body, a cover in which a valve element or the like is disposed is fixedly attached to the other end portion of the valve main body. However, when the cover is fixedly attached to the valve body, the cover may be inclined with respect to the valve body, and the valve element may be inclined to contact the valve seat. In the solenoid valve described above, since the copper pipe is brazed to the valve main body and the seat member, two brazing steps are required.

Detailed Description
(first embodiment)
An opening/closing valve according to a first embodiment of the present invention will be described below with reference to fig. 1 to 5. In this specification, the on-off valve includes a valve device in which a small amount of refrigerant flows in a closed state.
Fig. 1 is a longitudinal sectional view of an opening and closing valve according to a first embodiment of the present invention.
The opening/closing valve 1 of the first embodiment is used as, for example, a dehumidification valve for throttling a refrigerant during a dehumidification operation of an air conditioner. The opening and closing valve 1 is an electromagnetic valve in which a spool is driven by a magnetic force. The opening/closing valve 1 may be an electrically operated valve or the like in which a valve body is driven by the rotational force of an electric motor.
As shown in fig. 1, the opening/closing valve 1 includes: the valve includes a valve body 10, a seat member 20, a cover 30, a suction element 40 as a connection portion, a plunger 50, a valve body 60, and an electromagnetic coil 70.
The valve body 10 integrally includes a body portion 11, a seat member attachment portion 12, and a guide portion 13. The body portion 11 is formed in a cylindrical shape. The seat member mounting portion 12 is formed in a cylindrical shape having a larger diameter than the body portion 11. The seat member attachment portion 12 is provided continuously with the lower end portion of the main body portion 11. The guide portion 13 is formed in a cylindrical shape having a smaller diameter than the body portion 11. The guide portion 13 is connected to the upper end of the body portion 11. Both end portions of the valve main body 10 are opened. A valve chamber 14 is provided inside the valve body 10.
The seat member 20 integrally has a seat main body 21 and a flange 22. The seat main body 21 is formed in a cylindrical shape. The flange 22 is formed in an annular shape. The flange 22 is provided continuously with the lower end portion of the seat main body 21. A valve port 23 that opens into the valve chamber 14 is provided inside the seat main body 21. A valve seat 24 surrounding the valve port 23 is provided at an inner edge of the upper end portion of the seat main body 21. The valve seat 24 is an annular tapered surface whose diameter gradually decreases from the top toward the bottom. The valve seat 24 is provided with a plurality of escape grooves 25. The seat member 20 is fitted into the seat member mounting portion 12 of the valve body 10 (one end portion of the valve body 10). The flange 22 of the seat member 20 is fixedly attached to the seat member attachment portion 12 by brazing.
A first duct 16 extending laterally is fixedly attached to the main body portion 11 of the valve main body 10 by brazing. A second duct 17 extending downward is fixedly attached to a lower portion of the seat member 20 by brazing. The first conduit 16 is connected to the valve chamber 14. The second conduit 17 is connected to a valve port 23.
The cover 30 is formed in a cylindrical shape with the upper end closed. The cover 30 has a cylindrical portion 31 and a disc-shaped top portion 32 provided continuously to an upper end portion of the cylindrical portion 31. The cap 30 has the same inner diameter and the same outer diameter as the guide portion 13 of the valve body 10. The cover 30 is disposed on the guide portion 13 side (the other end portion of the valve body 10) of the valve body 10 so as to be coaxial with the valve body 10. The lower end 31a of the cylindrical portion 31 is fixedly attached to the guide portion 13 of the valve body 10 by welding.
The attraction member 40 is a fixed iron core magnetized by the electromagnetic coil 70. The suction member 40 is formed in a cylindrical shape. The suction member 40 is fixed to the cylindrical portion 31 of the cap 30. The suction element 40 is disposed such that a lower end portion 40a thereof protrudes downward from the cylindrical portion 31. The lower end portion 40a of the attraction member 40 is inserted into the guide portion 13. The lower end portion 40a of the attraction member 40 is inserted into the guide portion 13. The suction element 40 is a connection portion that connects the cover 30 and the valve body 10.
The outer diameter of the suction element 40 is the same as the inner diameter of the guide portion 13 of the valve body 10 and the inner diameter of the cylindrical portion 31 of the cap 30. Therefore, the outer peripheral surface of the suction element 40 is in contact with the inner peripheral surface of the guide portion 13 and the inner peripheral surface of the cylindrical portion 31 over the entire circumference, and the valve main body 10, the cover 30, and the suction element 40 are coaxially arranged. Thereby, the suction member 40 restricts the tilt of the cap 30 with respect to the valve main body 10. The outer peripheral surface of the suction element 40 may be in contact with the inner peripheral surface of the guide portion 13 and the inner peripheral surface of the cylindrical portion 31 over substantially the entire circumference. As long as the outer peripheral surface of the suction element 40 is in contact with these inner peripheral surfaces over substantially the entire circumference, the suction element 40 can restrict the inclination of the cover 30.
The plunger 50 is a movable iron core magnetized by an electromagnetic coil 70. The plunger 50 is formed in a cylindrical shape. The plunger 50 is disposed above the suction element 40 inside the cover 30. The plunger 50 is housed in the cover 30 so as to be movable in the vertical direction. The plunger 50 and the attraction member 40 sandwich a plunger spring 51 as a compression coil spring therebetween. When the plunger 50 and the attraction member 40 are magnetized, the plunger 50 is attracted by the attraction member 40 and moves downward. When the magnetization of the plunger 50 and the attraction member 40 is released, the plunger 50 is pushed by the plunger spring 51 and moves upward. The top 32 of the cap 30 serves as a stopper for determining the upper limit position of the plunger 50.
The valve body 60 includes a rod-shaped body portion 61 and a valve body portion 62 provided continuously to a lower end portion of the body portion 61. The body portion 61 is inserted through the suction element 40. The upper end of the barrel 61 is fixed to the plunger 50. The spool 60 moves in the vertical direction together with the plunger 50. The valve body 62 is disposed in the valve chamber 14 so as to vertically face the valve seat 24. That is, the valve body 60 is disposed to be able to advance and retreat with respect to the valve seat 24. The valve body 62 closes the valve port 23 by being in contact with (seated on) the valve seat 24 (valve-closed state). The valve body 62 is separated from the valve seat 24 to open the valve port 23 (open valve state).
The valve main body 10, the seat member 20, the cover 30, and the valve body 60 are made of metal such as stainless steel. The first conduit 16 and the second conduit 17 are made of metal such as copper. The valve main body 10, the seat member 20, the cover 30, the suction element 40, the plunger 50, and the valve body 60 are disposed so that their respective axes coincide with the axis L (i.e., so as to be coaxial).
The electromagnetic coil 70 is formed in a substantially cylindrical shape. The cover 30 is fitted inside the electromagnetic coil 70. A plate spring-like stopper 71 having a hemispherical convex portion is provided on the upper portion of the electromagnetic coil 70. The electromagnetic coil 70 is fixed to the cover 30 by fitting the hemispherical convex portion of the stopper 71 into the hemispherical concave portion provided in the cover 30.
The attraction member 40 and the plunger 50 are magnetized by energizing the electromagnetic coil 70. The magnetization of the attraction member 40 and the plunger 50 is released by not energizing the electromagnetic coil 70. The electromagnetic coil 70 functions as a drive unit in cooperation with the suction element 40, the plunger 50, and the plunger spring 51.
Next, an example of a method of assembling the opening/closing valve 1 will be described with reference to fig. 2 to 5. Fig. 2 to 5 are cross-sectional views illustrating an assembly method of the opening/closing valve of fig. 1, and sequentially show a brazing step, a valve seat adjusting step, a connecting step, and a welding step.
As shown in fig. 2, the first conduit 16 and the seat member 20 are virtually disposed to the valve body 10, and the second conduit 17 is virtually disposed to the seat member 20. Then, the brazing filler metal 80 is placed at each brazing site and then placed in a furnace. After the brazing material is melted in the furnace, the respective members are fixedly attached when the melted brazing material is solidified.
The valve body 10 and the seat member 20 may be distorted by the influence of high heat generated by the furnace, and the valve seat 24 may be misaligned or deformed. In the present embodiment, as shown in fig. 3, the position and shape of the valve seat 24 are adjusted by inserting the adjustment jig 90 from the guide portion 13 of the valve body 10. The adjustment jig 90 is formed in a cylindrical shape. The adjustment jig 90 has the same outer diameter as the inner diameter of the guide portion 13. The adjustment jig 90 has an annular tapered surface 91 at the distal end. Thus, when the adjustment jig 90 is inserted into the guide portion 13, the outer peripheral surface of the adjustment jig 90 is in contact with the inner peripheral surface of the guide portion 13 over the entire periphery, and the inclination of the adjustment jig 90 with respect to the valve body 10 is restricted. The adjustment jig 90 is positioned so as to be coaxially arranged with respect to the valve main body 10. The adjustment jig 90 is guided by the guide portion 13 so as to move in the direction of the axis L. Then, by pressing the tapered surface 91 against the valve seat 24, the valve seat 24 is adjusted in position so as to be coaxial with the guide portion 13 on the axis L, and the valve seat 24 is adjusted to have an appropriate shape.
Next, as shown in fig. 4, the suction element 40, the plunger 50, the plunger spring 51, and the valve body 60 are housed in the cover 30. At this time, the suction element 40 is disposed inside the cover 30 such that the lower end portion 40a of the suction element 40 protrudes downward from the lower end portion 31a of the cover 30. The cylindrical portion 31 of the cover 30 is struck with a punch, and the suction member 40 is fixed to the cylindrical portion 31. Then, the lower end portion 40a of the suction element 40 is inserted into the guide portion 13 while sliding the outer peripheral surface of the lower end portion 40a on the inner peripheral surface of the guide portion 13, so that the cylindrical portion 31 of the cover 30 is brought into contact with the guide portion 13.
Then, as shown in fig. 5, the lower end portion 31a of the cover 30 is welded to the guide portion 13 using a welding jig 95. The cover 30 is inserted to the inside of the electromagnetic coil 70, and the electromagnetic coil 70 is fixed by the stopper 71. Thus, the opening and closing valve 1 is completed.
As can be seen from the above, according to the method of assembling the opening/closing valve 1 of the present embodiment, the adjustment jig 90 is inserted into the guide portion 13 of the valve body 10, thereby adjusting the valve seat 24 fixedly attached to the seat member 20 of the valve body 10. Thereafter, the suction member 40 fixed to the cover 30 is inserted into the guide portion 13 of the valve body 10, and the valve body 10 and the cover 30 are fixedly attached by welding. In this way, after the seat member 20 is fixedly attached to the seat member attachment portion 12 of the valve body 10, the valve seat is adjusted by inserting the adjustment jig 90 from the opening of the guide portion 13 of the valve body 10, and the valve element 60 can be appropriately seated on the valve seat 24. Therefore, valve leakage can be effectively suppressed.
In addition, a guide portion 13 is provided at the valve body 10, and the guide portion 13 restricts the inclination of the cap 30 with respect to the valve body 10 by contacting with the outer circumferential surface of the suction member 40 fixed to the cap 30. Then, the suction member 40 is inserted into the guide portion 13 while sliding. This can suppress the inclination of the cover 30 with respect to the valve main body 10. In this way, when the cover 30 supports the valve element 60 so as to be able to advance and retreat with respect to the valve seat 24, the valve element 60 can be appropriately seated on the valve seat 24. Therefore, the valve leakage can be more effectively suppressed.
Further, the seat member 20 is fixedly attached to the valve main body 10 by brazing. Meanwhile, the first conduit 16 is fixedly mounted to the valve body 10 by brazing. Meanwhile, the second pipe 17 is fixedly attached to the seat member 20 by brazing. Thus, the valve main body 10, the seat member 20, the first conduit 16, and the second conduit 17 can be fixedly attached by one brazing process. Therefore, the number of brazing processes can be reduced. Even if the valve seat 24 is displaced or deformed due to the influence of the high temperature during brazing, the valve body 60 can be properly seated on the valve seat 24 because the valve seat 24 is adjusted thereafter.
(second to fourth embodiments)
An opening/closing valve according to second to fourth embodiments of the present invention will be described below with reference to fig. 6 to 8. In the embodiments described below, the same components as those of the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.
Fig. 6 to 8 are longitudinal sectional views of the opening/closing valve according to the second to fourth embodiments of the present invention in this order. In fig. 6 to 8, the electromagnetic coil 70 is not shown.
The opening-closing valve 2 of the second embodiment shown in fig. 6 has a valve main body 10A and a seat member 20A having different structures from those of the valve main body 10 and the seat member 20 of the opening-closing valve 1 of the first embodiment.
The valve body 10A has only the body portion 11 and the guide portion 13, and the seat member attachment portion 12 is omitted. Further, the seat member 20A integrally has a seat main body 21 and a large diameter portion 26. The large diameter portion 26 is formed in a cylindrical shape having a larger diameter than the seat main body 21. The large diameter portion 26 is connected to the lower end portion of the seat main body 21. The outer diameter of the large diameter portion 26 is the same as the inner diameter of the main body portion 11. When the seat member 20A is inserted from the lower end of the body portion 11 of the valve body 10A, the outer peripheral surface of the large diameter portion 26 abuts against the inner peripheral surface of the body portion 11. The valve main body 10A and the seat member 20A are arranged coaxially. Therefore, the valve body 60 can be properly seated on the valve seat 24 by suppressing the displacement of the valve seat 24.
The opening-closing valve 3 of the third embodiment shown in fig. 7 has a suction element 40A having a different structure from the suction element 40 of the opening-closing valve 1 of the first embodiment.
The outer diameter of the lower end portion 40A of the attraction member 40A is the same as the inner diameter of the guide portion 13. The outer diameter of the upper end portion 40b of the suction element 40A is the same as the inner diameter of the cylindrical portion 31 of the cap 30. The outer diameter of the central portion 40c of the suction member 40A is the same as the outer diameters of the guide portion 13 and the cover 30. The lower end 40A of the attraction member 40A is inserted into the guide portion 13. The upper end portion 40b of the suction member 40A is inserted into the cover 30. The cover 30 and the guide portion 13 are fixedly attached to the suction element 40A as a connection portion by welding. The upper end portion 40b of the suction element 40A is inserted into the cover 30, and the upper end portion 40b functions as a guide portion for the cover 30. This can suppress the inclination of the cover 30 with respect to the valve main body 10.
The opening-closing valve 4 of the fourth embodiment shown in fig. 8 has a guide portion 13A and a cover 30A. The length of the guide portion 13A in the direction of the axis L is longer than the guide portion 13 included in the opening and closing valve 1 of the first embodiment. The cover 30A has a shorter length in the direction of the axis L than the cover 30 of the opening/closing valve 1 of the first embodiment.
