Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pressure regulator for compressed air pressure having a drain discharge part used for controlling the supply pressure of pneumatic equipment for general industry.

[0002]

[Prior art]

 In a pressure regulator with a drain discharge part, the drain valve must always be on the ground side. This is because otherwise drainage will be difficult to collect and drain. This pressure regulator was mainly used for setting the supply pressure of instruments, etc., and there was an unavoidable restriction on the attachment of the pressure regulator depending on the position of the air supply port of those instruments.

[0003]

[Problems to be solved by the device]

 Since this type of pressure regulator is set so that the drain discharge part is facing downward, it was common for the piping between the pressure regulator and the instrument to have a wide variety of arrangements. That is,

FIG. 12 shows a row of conventional pressure regulators. In the illustrated pressure regulator, by rotating the adjusting screw 21 and compressing the pressure adjusting spring 23, the port rod 25 is pushed through the diaphragm 24 to open the port, and the air pressure from the air supply port 27 is accumulated in the drain. It is guided to the diaphragm pressure chamber 28 via the portion 31 and the filter 30.

When the diaphragm 24 receives this pressure, it opposes the force generated by the pressure-adjusting spring 23 and creates an equilibrium state. The pressure of the diaphragm pressure chamber 28 is equal to the pressure introduced to the output port 29, and the output pressure corresponding to the force generated by the pressure adjusting spring 23 can be obtained. The part that operates in this way is called a pressure regulator. This is composed of members 21 to 29, which are referred to by the reference numerals in FIG. The bonnet 22 and the case 26 form an outer casing of this pressure regulating section, but the drain valve 33 existing at the bottom of the case 22 is always set to the ground side, so the bonnet 22 is always on the upper side. Will be located in. The drain reservoir 31, the filter 30, the drain valve 33, etc. constitute a drain discharge unit.

13 to 18 show examples of use of the pressure regulator shown in FIG. The supply pressure enters from the supply port 27, is guided to the output port 29, and is supplied to the meter 35 via the conduit 34. Since the drain valve 33 attached to the pressure regulator is mounted toward the ground side, that is, downward, only one position can be selected, and depending on the direction of the pressure connection port 36 of the meter 35, as shown in the figure. Therefore, complicated pipe connections must be made. However, such a pipe connecting method has a problem that it not only requires a lot of assembly man-hours but also causes a failure. The present invention is an epoch-making one intended to solve these problems.

[0007]

[Means for solving problems]

In the pressure regulator with the drain valve of the present invention shown in FIGS. 1 to 5, the pressure regulator 10 is 10 is provided with three output ports for sending the pressure-adjusted air to the required measuring instrument 15, It is the one that has been designed.

The pressure adjusting unit 10 includes an adjusting screw 1, a bonnet 2, a pressure adjusting spring 3, a diaphragm 4, a port rod 5, an atmosphere opening side valve port 17, a high pressure side valve port 18, a case 6, and air supply ports 7a, 7b. , Diaphragm pressure chamber 8, output ports 9a, 9b, 9c, etc. The drain discharge part is composed of a drain case 20, a cylindrical filter 16, a drain reservoir 11, air supply ports 7a and 7b, a bottom lid 12, a vent port 14 to the diaphragm pressure chamber 8, and the like.

[0009]

[Action]

Various examples in which the pressure regulator with the drain valve according to the present invention is connected to the desired instrument 15 by piping are shown in FIGS. 6 to 11. It can be seen that the condition of the piping is extremely good as compared with the conventional piping of the pressure regulator shown in FIGS. Very good piping like this So that the air whose pressure is adjusted here is sent to the required meter 15 in the pressure adjusting unit 10. Things. In using the air supply ports 7a and 7b, for example, it is convenient to use the left air supply port 7a in FIGS. 8 and 10 and the right side in FIGS. 9 and 11. It is convenient to use the air supply port 7b. In such a convenient use condition, the drain case 20 is provided with two compressed air supply ports, and the supply ports 7a and 7b are flat surfaces whose axes YY are orthogonal to the axis AA of the drain case 20. It is based on the configuration provided above so as to be parallel to the axis XX of the two output ports 9a and 9c. The air inlets 7a and 7b and the output outlets 9a, 9b and 9c which are not used are provided with blind lids. Thus, the axial centers YY of the air supply ports 7a and 7b of the drain case 20 are substantially aligned with the tangent line of the outer peripheral circle of the cylindrical filter 16.

[0010]

【Example】

 The present invention has the configuration shown in FIGS. 1 to 5 as described above. A drain valve 13 is provided at the inner lower end of the drain reservoir 11 in the cylindrical filter 16, and a dust collecting and discharging means 40 is provided between the cylindrical filter 16 and the drain case 20. In the illustrated example, the dust collecting and discharging means 40 is the bottom lid 12 which is attached to the lower end portion 39 of the drain case 20 and the lower end portion 38 of the cylindrical filter 16 so as to be able to come into contact with and separate from the bottom lid body 12. As shown in FIG. 5, the bottom cover 12 has an outer thread portion 41 that is screwed into the inner thread portion 37 of the lower portion of the drain case 20, and is provided with an O-ring 42 to prevent water leakage to the outside of the case. Is being prevented.
