Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a sanitary pressure gauge or a mounting bracket for a sanitary pressure transmitter.
[0002]
[Prior art]
Conventionally, as shown in FIG. 4, a sanitary pressure gauge or a sanitary pressure transmitter formed by connecting a short branch pipe 12 in the middle of a pipe 11 and providing a connection flange 13 at an outer end of the branch pipe 12. The 14 mounting pipes 15 are known (hereinafter referred to as Conventional Example 1).
[0003]
However, in the mounting pipe 15 according to the above-described conventional example 1, the branch pipe 12 is a so-called riser pipe, and therefore, a liquid pool (stagnation of liquid) is generated inside, and the cleaning property is deteriorated. There was a problem.
[0004]
In addition to the above-described conventional example 1, as shown in FIGS. 5 to 7, a greatly expanded spherical portion 17 is integrally provided in the middle of the pipe 16 by casting or the like, and is connected to the wall surface of the spherical portion 17. A mounting pipe 21 for a sanitary pressure gauge or a sanitary pressure transmitter 20 formed by providing a connection flange 19 at the opening edge of the connection round hole 18 after opening the connection round hole 18 is known. (Hereinafter, Conventional Example 2).
[0005]
That is, in order to solve the above-mentioned problems, as in the above-mentioned conventional examples 1 and 2, the sanitary pressure gauge or the sanitary pressure transmitter is mounted with (1) short rising, or (2) spherical part. Although the method of mounting to a body with a hole is adopted, the above (1) cannot reduce the rising length to 0, and (2) is the flow of the part flowing from the liquid conduit (circular pipe) to the spherical part. However, there is a problem that peeling is inferior in cleaning performance, and that a relatively complicated and costly operation of connecting branch pipes and providing a spherical portion is required.
[0006]
Incidentally, the applicant of the present application could not find a related prior art document by searching the prior art.
[0007]
[Problems to be solved by the invention]
An object of the present invention is to provide a novel pressure gauge and a mounting bracket for a pressure transmitter devised to solve the above problems.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the pressure gauge according to the present invention, the mounting bracket of the pressure transmitter, when considered in a cross section perpendicular to the axis of the pipe, the inner surface of the pipe and the diaphragm surface are flush or nearly flush. It is characterized by being formed in a state.
[0009]
And, a state in which the inner surface of the pipe and the diaphragm surface are flush or nearly flush is formed through a burring tube.
[0010]
The pressure transmitter includes a pressure detector main body including a pressure gauge that detects the pressure of the fluid introduced into the pipe through the diaphragm surface and outputs a detection signal, and detects a pressure based on the detection signal. And a display device for performing display.
[0011]
The pressure gauge and the pressure transmitter are of a sanitary type.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
In the embodiment of the present invention shown in FIGS. 1 to 3, a small processing hole (not shown) is formed in a wall at an intermediate position of the pipe 1, and a burring process is performed on an opening edge of the processing hole. The burring tee portion 4 is provided on a wall at a point in the middle of the first portion, and the upper end of the burring tee portion 4 is cut off to provide a connection round hole 5, and a connection flange 6 is provided at an opening edge of the connection round hole 5. Thus, the mounting pipe 8 of the sanitary pressure gauge or the sanitary pressure transmitter 7 is obtained.
[0013]
The pressure transmitter 7 includes a sanitary pressure gauge 9 that detects a pressure of a fluid introduced into the pipe 1 and outputs a detection signal corresponding to the detected pressure. And a display 10 for displaying pressure based on the detection signal output from the control unit 9.
[0014]
As shown in FIGS. 1 and 2, the pressure transmitter 7 is sealed by a seal 31, fitted into the connection round hole 5, and fixed by a clamp 32.
[0015]
Reference numeral 2 in the drawing indicates a diaphragm surface provided in the pressure detector main body 9.
[0016]
[Action]
Since this embodiment is as described above, when the connecting round hole 5 is obtained, the height of the outer surface of the opening edge of the connecting round hole 5 is set to be the same as the outer circumferential surface of the pipe 1. That is, it is desirable to adopt a configuration in which there is no branch pipe (the rising length is set to 0).
[0017]
【The invention's effect】
Since the mounting bracket of the pressure gauge and the pressure transmitter according to the present invention has the above-described configuration, the rising length can be set to 0 or infinitely close to 0, and the intended purpose is completely achieved. Has a significant effect.
