Abstract
Description
Technical Field
[0001] This invention relates to a steam pipe drainage device, specifically a steam pipe drainage device applicable to two different methods. Background Technology
[0002] Traditional steam pipe condensate drain fittings consist of a working steel pipe, a tee condensate drain fitting, a steel pipe short section, end caps, a drain pipe, an insulation layer, and an outer protective pipe. Because the traditional steam pipe condensate drain fitting requires a tee + steel pipe short section + end cap, it not only increases the materials needed for the steel pipe short section, insulation material, and outer protective pipe, but also adds the workload of welding two welds, X-ray non-destructive testing, and a two-day production cycle. It also increases heat loss in the steam-insulated pipeline, raises the risk of steam leakage, and brings many inconveniences to the installation of prefabricated insulated pipelines. After the pipeline is installed, it is prone to deformation due to its own weight and vibrations generated during operation. Furthermore, the condensate drain fitting lacks impurity cleaning measures, which can easily lead to a decrease in pipeline patency over long-term use.
[0003] In view of this, the present invention designs a steam pipe drainage device that can be applied to overhead or direct burial methods. Summary of the Invention
[0004] The main purpose of this disclosure is to provide a steam pipe drainage device that can not only reduce manufacturing costs and improve the overall insulation effect, but also solve the welding problem of the tee end cap, and facilitate the on-site installation and construction of overhead steam pipes.
[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:
[0006] A steam pipe draining device includes a main steam pipe, a sealed tee fitting, and a drain pipe. The main steam pipe is fixedly installed on both the left and right ends of the sealed tee fitting, and the main steam pipe bodies on both sides are coaxially arranged. A rotating end cap is fixedly installed on the third end of the sealed tee fitting, and the rotating end cap is integrally formed with the sealed tee fitting. A drain pipe is fixedly connected to the rotating end cap, and the drain pipe extends outward.
[0007] A cleaning pipe is fixedly installed on the top of the sealing tee fitting, and a movable filter screen is movably installed inside the cleaning pipe, extending into the sealing tee fitting. The movable filter screen is located above the drain pipe.
[0008] Preferably, the cleaning pipe is a square pipe with a blind-path structure, and the movable filter screen is slidably installed inside the square pipe, that is, the side of the movable filter screen slides in contact with the inner wall of the square pipe. The cleaning pipe is provided with a driving mechanism to move the movable filter screen.
[0009] Preferably, the driving mechanism includes a movable slider and a Z-axis one-way screw. The Z-axis one-way screw is rotatably mounted on the top of the cleaning pipe, and the movable slider is threaded onto the Z-axis one-way screw, with the movable slider embedded in the middle of the movable filter screen.
[0010] Preferably, a U-shaped mounting frame is fixedly installed on the top of the cleaning pipe, and the U-shaped mounting frame is upside down. A small servo motor is fixedly installed on the U-shaped mounting frame, and the top end of the Z-axis unidirectional lead screw extends outward from the cleaning pipe and is fixedly connected to the output end of the small servo motor.
[0011] Preferably, the upper part of the movable filter screen is inclined, that is, the cross-section of the movable filter screen is an isosceles trapezoid.
[0012] Preferably, a plurality of slag discharge pipes arranged in a ring array are fixedly installed on the side of the cleaning pipe, and each slag discharge pipe has a threaded plug installed at its outer end. The slag discharge pipe is located above the movable filter screen.
[0013] Preferably, a pressure relief valve is installed on the slag discharge pipe.
[0014] Preferably, a pipe sleeve is fixedly installed on the outside of the main steam pipe, and the pipe sleeve wraps around the sealing tee fitting. The pipe sleeve consists of an insulation layer and an outer protective layer, and the drain pipe penetrates through the pipe sleeve.
[0015] In view of this, compared with the prior art, the beneficial effects of the present invention are:
[0016] (i) In this application, the steel pipe section is eliminated, the manufacturing cycle is shortened, the cost is reduced, and the workload of X-ray non-destructive testing is reduced.
[0017] (ii) This application greatly reduces the risk of steam leakage.
[0018] (III) In this application, the vertical height of the drainage joint is shortened by ≥200mm, saving space.
[0019] (iv) In this application, the materials for insulation and outer protective pipe are saved, reducing heat loss over the years, and the energy-saving and environmental protection effects are significant.
[0020] (v) This application applies to buried or overhead steam pipelines, which is convenient for on-site installation.
[0021] (vi) In this application, the movable filter screen is used to block impurities and prevent them from entering the water supply pipe. When cleaning, the small servo motor works, which drives the Z-axis one-way screw to rotate, so that the movable slider drives the movable filter screen to gradually rise until it moves to the position of the slag discharge pipe. Opening the threaded plug cap can discharge the impurities on the movable filter screen to keep the inside clean and provide a guarantee for long-term unobstructed flow. Attached Figure Description

[0032] Please see Figure 1-7 The present invention provides the following embodiments:
[0033] A steam pipe draining device includes a main steam pipe 1, a sealed tee fitting 2, and a drain pipe 4. The main steam pipe 1 is fixedly installed on both the left and right ports of the sealed tee fitting 2, and the main steam pipe bodies on both sides are coaxially arranged. A rotating end cap 3 is fixedly installed on the third port of the sealed tee fitting 2, and the rotating end cap 3 is integrally formed with the sealed tee fitting 2. The drain pipe 4 is fixedly connected to the rotating end cap 3, and the drain pipe 4 extends outward.
[0034] A cleaning pipe 6 is fixedly installed on the top of the sealing tee fitting 2. A movable filter screen 10 is movably installed inside the cleaning pipe 6 and extends into the sealing tee fitting 2. The movable filter screen 10 is located above the drain pipe 4.
[0035] Specifically, the cleaning pipe 6 is a square pipe with a blind path structure. The movable filter screen 10 is slidably installed inside the square pipe, that is, the side of the movable filter screen 10 slides in contact with the inner wall of the square pipe. The cleaning pipe 6 is equipped with a driving mechanism to move the movable filter screen 10.
[0036] Specifically, the driving mechanism includes a movable slider 11 and a Z-axis one-way screw 12. The Z-axis one-way screw 12 is rotatably mounted on the top of the cleaning pipe 6. The movable slider 11 is threaded onto the Z-axis one-way screw 12 and is embedded in the middle of the movable filter screen 10. A U-shaped mounting frame 13 is fixedly mounted on the top of the cleaning pipe 6 and is upside down. A small servo motor 14 is fixedly mounted on the U-shaped mounting frame 13. The top end of the Z-axis one-way screw 12 extends outward from the cleaning pipe 6 and is fixedly connected to the output end of the small servo motor 14.
[0037] Specifically, the upper part of the movable filter screen 10 is inclined, that is, the cross-section of the movable filter screen 10 is an isosceles trapezoid. Several slag discharge pipes 7 arranged in a ring array are fixedly installed on the side of the cleaning pipe 6. Each slag discharge pipe 7 has a threaded plug 8 threaded on its outer end. The slag discharge pipe 7 is located above the movable filter screen 10 and is used to remove blocked impurities.
[0038] Specifically, a pressure relief valve 9 is installed on the slag discharge pipe 7 to make the use of the steam pipeline safer.

[0040] The specific implementation method of this embodiment is as follows: by integrally processing the sealing tee fitting 2 and the rotating end cap 3, the short section of the steel pipe is avoided, thereby reducing the production workload and the space occupied.
[0041] The movable filter screen 10 is used to block impurities and prevent them from entering the drain pipe 4. During cleaning, the small servo motor 14 operates, which drives the Z-axis one-way lead screw 12 to rotate, causing the movable slider 11 to gradually raise the movable filter screen 10 until it moves to the position of the slag discharge pipe 7. Opening the threaded plug 8 allows the impurities on the movable filter screen 10 to be discharged, thus maintaining internal cleanliness and ensuring long-term unobstructed flow.
