DETAILED DESCRIPTION

[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings.

[0018] like Figs. 1-2 As shown, a vertical tubular water seal includes a pipe 1, a water seal cavity 2, a base plate 3, a cover plate 4, an inlet pipe 5, an outlet pipe 6, a drain pipe 7, and a threaded cap 8. The lower end of the pipe 1 is connected to the circular base plate 3, and the upper end is connected to the circular cover plate 4. The inlet pipe 5 is connected to the cover plate 4, with its upper end extending beyond the cover plate 4. There is a gap between the outlet at its lower end and the base plate 3, and the axis of the inlet pipe 5 is parallel to the axis of the pipe 1. The outlet pipe 6 is connected to the base plate 3, with a gap between the inlet at its upper end and the cover plate 4, and a gap between its lower end and the base plate 3. The water outlet pipe 6 is connected to the pipe cylinder 1, and the axis of the water outlet pipe 6 is parallel to the axis of the pipe cylinder 1. The water outlet pipe 6 is characterized by having one or more one-way valve plates 62 on its peripheral wall. The one-way valve plates 62 are installed in the mounting hole, and the lower end of the one-way valve plate 62 is higher than the lower end of the water outlet pipe 5. When the water pressure or water volume in the water seal chamber 2 is A, the water in the tubular water seal flows from the water inlet at the upper end of the water outlet pipe 6. When the water pressure or water volume in the water seal chamber 2 is B, which is greater than A, the water in the tubular water seal flows from the water inlet at the upper end of the water outlet pipe 6 and the one-way valve plate 62 together.

[0019] In the event of a sudden and unexpected situation where the water pressure or flow rate exceeds the preset value A (at which point the water pressure or flow rate is B), this invention addresses this by installing one or more one-way valve plates 62 on the peripheral wall of the outlet pipe 6. In a short time, when the water pressure or flow rate in the water seal chamber 2 is A, the water in the tubular water seal flows out from the inlet at the upper end of the outlet pipe 6. When the water pressure or flow rate in the water seal chamber 2 is greater than A (B), the water in the tubular water seal flows out from both the inlet at the upper end of the outlet pipe 6 and the one-way valve plate 62, thereby enabling rapid drainage and preventing blockage / stagnation in the pipeline system.

[0020] Furthermore, the lower end of the inlet pipe 5 is provided with a first annular portion 52 and a second annular portion 53, which are L-shaped. The lower end of the second annular portion 53 is located below the lower end of the first annular portion 52, and the lower end of the first annular portion 52 is located below the outlet of the inlet pipe 5. By providing the first annular portion 52 and the second annular portion 53, this invention can reduce the impact of the water flowing from the inlet pipe 5 on the outlet pipe 6 and the one-way valve plate 62, thus having a flow-slowing effect.

[0021] Further, the bottom plate 3 is inclinedly arranged, and the bottom end of the bottom plate 3 is inclinedly arranged to one side of the water outlet pipe 6, so that the sundries are conveniently gathered to one side of the water outlet pipe 6.

[0022] Further, the cover plate 4 is slightly inclinedly and protrudingly arranged to the center part, the relief pipe 7 is arranged in the center part, the threaded cap 8 is arranged on the relief pipe 7, the relief pipe 7 is arranged between the water outlet pipe 6 and the water inlet pipe 5, and the threaded cap 8 has a visible transparent part. Through the design of the relief pipe 7 and the threaded cap 8, the air pressure of the water seal cavity 2 can be adjusted, and the excessive sundries or water can be discharged, and the visible transparent part of the threaded cap 8 can be used for observing the sundries in the pipe type water seal.

[0023] The upper end of the water inlet pipe 5 is provided with a first threaded part 51, and the lower end of the water outlet pipe 6 is provided with a second threaded part 61, which are used for being threadedly connected with corresponding pipelines.

[0024] Further, the upper end of the water outlet pipe 6 has an axial gap H1 with the cover plate 4, and the lower end of the water inlet pipe 5 has an axial gap H2 with the bottom plate 3, H1>H2, and Wherein, P1 is the maximum pressure in the water seal cavity 2, P2 is the opening pressure of the one-way valve piece 62, K is a proportional coefficient, which is set according to the pressure and flow of the pipeline system where the vertical pipe type water seal is arranged, and when calculating, the dimensionless numerical value part of H1, H2, P1 and P2 is taken. Through the design, the smoothness of the vertical pipe type water seal can be improved, and the pipeline system can be prevented from being blocked.

[0025] The vertical pipe type water seal of the application can quickly drain water and prevent the pipeline system from being blocked in a short time when the water pressure or water volume is A (at this time, the water pressure or water volume is B) due to the sudden emergence of the water pressure or water volume greater than the preset water pressure or water volume.

[0026] Through the arrangement of the first annular part 52 and the second annular part 53, the impact of the water outlet of the water inlet pipe 5 on the water outlet pipe 6 and the one-way valve piece 62 can be reduced, and the flow can be slowed down. The smoothness of the vertical pipe type water seal can be improved, and the pipeline system can be prevented from being blocked.

[0027] The above embodiments are illustrative of the present application and are not limiting of the present application. It is to be understood that variations, modifications, substitutions and changes can be made without departing from the spirit and scope of the present application, which are defined by the appended claims and their equivalents.
