Description

[Detailed description of the invention] [Field of industrial application] This invention is installed at each entrance terminal of a drainage system as an odor control device to prevent sewage gas containing unpleasant odors from entering the room inside the drainage pipe. When a drainage trap is installed in a building and a completion inspection is performed, the internal pressure fluctuation value can be read easily, reliably, and stably without a measuring device.

[Conventional technology]

When inspecting the water seal status of a drain trap, the method used was to insert a measuring stick into the water seal part, hold it vertically, and read it.

However, these conventional methods have the following drawbacks and inconveniences.

When measuring, there are individual differences and sometimes the measurer is not placed in a fixed position, resulting in large measurement errors.

If water falls below the odor-proof wall of the drainage trap, measurement errors may occur.

Since it is difficult to read if the measurer is placed vertically, the measurer is often placed diagonally, resulting in unstable and uncertain measurements.

Not only is a measurer required for measurement, but at the same time, it is necessary to prepare measures for each area to be inspected for the completion inspection of an apartment complex.
There was a lot of waste.

Sometimes, when taking out a used measurer, the floor surface was stained.

During the completion inspection, the measurer must be accurately placed in a fixed position, which is a tedious task.

[Problem that the invention attempts to solve]

When inspecting the water sealing status of a drain trap, the present invention displays a pressure fluctuation scale in the pipe at a reference position on the deodorizing wall of the drain trap in advance so that it can be easily visually observed and the fluctuation in the pipe pressure can be measured. This eliminates all the drawbacks and inconveniences found in conventional technology.

A major requirement for the drainage traps installed at each inlet terminal of the drainage system is that they be designed so that the trap water seal will not be broken.

For this reason, there are design methods for gravity drainage ventilation systems, such as the one exemplified by the Air Conditioning Society of Japan's standard "HASS206 Water Supply and Drainage Equipment Standards."

Generally, a completion inspection is carried out for housing complexes, condominiums, etc. when construction is completed (before occupancy or handover), but when it comes to drainage ventilation equipment, the main items are the degree of pressure fluctuation throughout the drainage pipes and drainage performance. It has been confirmed as.

The judgment is based on the “HASS206 water supply and drainage equipment standards” mentioned above.
The goal is to pass the exam.

[Means for solving problems]

In the present invention, a deodorizing wall 3 is disposed near the drain port inside the main body 1 having a drain port 2 to the drain pipe 6 so as to face the drain port 2, and the drain port is connected from the inside of the main body 1 to the upper part of the deodorizing wall 3. 2 to form a pipe cleaning port 4 equipped with a removable blocker plug 5 for inserting a cleaning elongated body into the drain pipe 6, and set the reference position 7 at the zero point 9 on the side of the pipe cleaning port 4 to measure the internal pressure of the pipe. Variable scale 8
is displayed.

[Effect]

The method of inspecting drainage and ventilation systems upon completion of construction of apartment complexes and condominiums is to simultaneously drain water from the top floor of the building using a combination of various devices, and then examine the pressure fluctuations in the pipes on each lower floor. There is.

First, drain water from all appliances on the top floor (bath, toilet, washing pan, sink, etc.) at the same time.

On the other hand, on each floor leading up to the top floor, each person went to each floor and read the fluctuation value of the water seal level by placing a measuring tape in the correct vertical position on the water seal part of the drain trap of the bathroom or washing pan. .

The reading value indicates that the pressure fluctuation is on the positive side during simultaneous drainage,
Read and record each maximum value on the - side. It is determined whether the value is within the allowable range of the design value.

In this invention, by displaying the pipe pressure scale near the blockage plug 5 of the odor-proof wall 3, which is a place where the drainage trap can be easily viewed directly, it is possible to easily and accurately measure the pipe pressure fluctuation value during the ventilation and drainage performance tests during completion inspections. It has become possible to read reliably without any measuring equipment.

In other words, it drains water from all the fixtures on the top floor at the same time and reads how the amount of water sealed in the drain traps of all fixtures on each floor changes.

On the lower floors, water could overflow or be sucked in due to changes in the pressure inside the pipes, so it was necessary to accurately investigate the situation during the completion inspection.

In this invention, by setting the water surface line of approximately 50 mm of water seal as the reference position 7, the zero point 9 of the pipe pressure fluctuation scale 8 is set and displayed at the reference position 7, so that completion inspection can be easily performed at the same time. Ta.

Additionally, residents can check the amount of water sealed and whether or not it is present at any time after moving in, making it possible to prevent odors from flowing back due to water seal failure.

When you are away for a long time, the water seal decreases due to evaporation or other factors, causing a backflow of odors, so you can work in a way that prevents the water seal from breaking.

The in-pipe pressure fluctuation scale display may be directly cast when molding the main body, or may be integrated by fitting a scale display plate and bonding.

Furthermore, if a sensor or a sounding body is attached near the danger indicator 10, where the seal water is below zero point 9, which is the reference position 7, the seal water may flow due to the pressure inside the pipe and the odor may flow back. There is also the advantage of being able to replenish the sealed water.

[Effect of idea]

According to this invention, the scale is displayed near the blockage plug on the odor-proof wall, which is a place that is easy to see directly in the drainage trap, so it is easy to easily and reliably stabilize the internal pressure fluctuation values during ventilation and drainage performance inspections during completion inspections. Not only can it be read without a measuring device, but residents can also check it at any time even after they move in, making it possible to prevent odors from flowing back due to broken water seals.
