Description

Technical Field

[0001] The utility model relates to the technical field of water traps of drainage pipes, in particular to an S-shaped combined water trap device which is visible and can restore the water seal height. Background Art

[0002] The water trap is one of the main accessories of drainage pipes in the construction industry. It refers to a kind of accessory with a water seal inside the sanitary ware or on the drainage pipe section of the ware. Its function is to use a certain height of static water pressure to resist the pressure change in the drainage pipe, isolate and prevent the rancid, harmful, flammable gases and small insects produced by the drainage pipe from entering the room through sanitary ware, floor drains, etc. and polluting the environment. The water seal is achieved by using a certain height of water column in the water trap. The water seal of the water trap should meet the water column requirements of a certain height. The water seal height of the water trap is generally 50~100mm, which is more reasonable.

[0003] However, the water seal of the trap is easily damaged due to reasons such as insufficient water seal depth. If the interval between uses is too long and water is not replenished for a long time, the water surface of the water seal will continue to evaporate and lose its water seal function, which is not easy to be found. This is the main reason for the escape of odor. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an S-shaped combined water trap device which is visible and can restore the water seal height, and can effectively solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above problems, the technical solution adopted by the utility model is: a visible S-shaped combined water trap device that can restore the water seal height, characterized in that it includes an upstream P-type tube, a transparent straight tube and a downstream P-type tube, the transparent straight tube is arranged between the upstream P-type tube and the downstream P-type tube, one end of the transparent straight tube is connected to the upstream P-type tube, and the other end is connected to the downstream P-type tube; a drain outlet is opened at the bottom of the upstream P-type tube, and a water injection port is opened at the top of the downstream P-type tube.

[0006] Preferably, the upstream P-type tube is connected to the transparent straight tube and the downstream P-type tube to form an S shape.

[0007] Preferably, the upstream P-type tube and the downstream P-type tube are made of rigid polyvinyl chloride material, and the transparent straight tube is made of transparent plastic material.

[0008] Preferably, the transparent plastic material is polymethyl methacrylate, polycarbonate or polyethylene terephthalate.

[0009] Preferably, the diameter of the transparent straight tube is DN50 to DN110.

[0010] Preferably, the transparent straight tube is connected to the upstream P-type tube and the downstream P-type tube using a PVC special adhesive.

[0011] Compared with the prior art, the utility model provides an S-shaped combined water trap device which is visible and can restore the water seal height, and has the following beneficial effects:

[0012] The utility model can utilize the visual performance of the transparent straight pipe according to actual needs to facilitate maintenance personnel to regularly inspect the water seal height. When the water seal height is insufficient, water can be replenished in time through the water injection port of the downstream P-type pipe to avoid evaporation of water in the water trap and ensure the water seal height of the water trap; sewage or rainwater debris can be cleaned through the drain port;

[0013] The water seal height in the trap can be checked in real time. When the water seal height is less than 50mm, water can be replenished in time to ensure that the water seal is not damaged and effectively avoid the return of odor in the drain pipe. The whole design structure is simple and easy to install, and the market for promotion and application is broad. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0017] Reference Figure 1 The utility model provides an S-shaped combined water trap device which is visible and can restore the water seal height, characterized in that it comprises an upstream P-type tube 1, a transparent straight tube 2 and a downstream P-type tube 3, wherein the transparent straight tube 2 is arranged between the upstream P-type tube 1 and the downstream P-type tube 3, one end of the transparent straight tube 2 is connected to the upstream P-type tube 1, and the other end is connected to the downstream P-type tube 3; a drain port 4 is provided at the bottom of the upstream P-type tube 1, and a water injection port 5 is provided at the top of the downstream P-type tube 3.

[0018] Preferably, the upstream P-type tube 1 is connected to the transparent straight tube 2 and the downstream P-type tube 3 to form an S shape.

[0019] Preferably, the upstream P-type tube 1 and the downstream P-type tube 3 are made of rigid polyvinyl chloride (UPVC) material, and the transparent straight tube 2 is made of transparent plastic material.

[0020] Preferably, the transparent plastic material is polymethyl methacrylate (PMMA), polycarbonate (PC) or polyethylene terephthalate (PET).

[0022] Preferably, the transparent straight tube 2 is connected to the upstream P-type tube 1 and the downstream P-type tube 3 using a PVC special adhesive.

[0023] As a specific embodiment of the utility model:

[0024] The device is mainly used at the bottom of the drainage riser. When connected, one end of the S-shaped water trap is connected to the drainage riser, and the other end is connected to the bottom riser. For example, a PVC pipe can be used for plug-in connection. If a metal pipe is used, a special connector can also be used for connection. The S-shaped water trap is provided with a water injection port 5 at one end and a drain port 4 at the other end. The water injection port 5 can be used to add water to restore the water seal when the water seal height is insufficient, and the drain port 4 can be used to clean sewage or rainwater debris.
