Description

Technical Field

[0001] The present invention belongs to the technical field of steam traps, and specifically relates to a condensate discharge device for a nozzle-type steam trap. Background Art

[0002] In industry, steam is often used as a heat source for heating objects. After the steam used as a heat source liquefies, it forms condensate. The condensate will reduce the heating effect of the steam and is also the cause of the so-called "water hammer" phenomenon. Therefore, in places such as factories, it is necessary to install steam traps at positions such as production pipelines to appropriately discharge the condensate.

[0003] In the prior art, during long-term use and observation, it is found that the amount of condensate generated by existing steam traps fluctuates with the environment. When the amount of condensate generated fluctuates, if the steam trap cannot discharge the condensate in a timely and effective manner, it will cause excessive condensate to accumulate in the steam pipeline and equipment. This part of the condensate will absorb the heat of the steam, making the thermal energy of the steam unable to be fully transferred to the heat-using equipment, thereby increasing the heat loss. Moreover, when the amount of condensate generated suddenly increases, if the drainage capacity of the steam trap is insufficient, a water plug will form in the pipeline. When the steam meets the water plug, a water hammer phenomenon will occur. The water hammer will cause the vibration and noise of the pipeline, and may cause the loosening of the pipeline connectors, pipeline rupture, and even damage to steam equipment such as the tube bundle rupture of a steam heat exchanger in the long run, affecting the normal operation and service life of the equipment. Therefore, the present invention provides a condensate discharge device for a nozzle-type steam trap. Summary of the Invention

[0013] The beneficial effects of the present invention are as follows:

[0014] 1.

Detailed implementation mode

[0030] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with the detailed implementation mode. In each figure, the Z direction represents the up and down direction, and the X direction and the Y direction are orthogonal to the Z direction.

[0031] Such as Figure 1 - Figure 11As shown in the figure, a nozzle type steam trap condensate discharge device according to an embodiment of the present invention includes a main body 2; the main body 2 is box-shaped and made of a metal material, and has an inlet 6, an outlet 7, and a flow path 8; the inlet 6 is used to introduce condensate into the interior of the main body 2, the outlet 7 is used to discharge condensate to the outside of the main body 2, and the flow path 8 extends from the inlet 6 to the outlet 7 and forms a plurality of first specific spaces 11, second specific spaces 12, third specific spaces 13, and a discharge space 14; during operation, the main body 2 serves as the core load-bearing structure, which is made into a box shape by a high-strength metal material. Its spacious internal space can accommodate a large amount of condensate and provide a stable installation foundation for each component. In a large system, under the drive of the system pressure difference, the condensate enters the main body 2 quickly and smoothly through the inlet 6 with a pipe diameter adapted to the condensate generation amount of the large system. The flow path 8 is carefully arranged to guide the condensate to pass through a plurality of specific spaces 11-13 in sequence for treatment, and finally discharged through the outlet 7. The position and direction of the outlet 7 are precisely planned to be adapted to the external drainage system, and the condensate is efficiently discharged by using gravity and the inertia of the water flow, avoiding water accumulation from damaging the equipment. Through this design, in the face of fluctuations in the condensate generation amount, the box-shaped metal structure of the main body 2 and the reasonably arranged flow path 8 can flexibly adapt to different flow rates of condensate. When the condensate generation amount increases, the spacious flow path 8 and the first specific space 11, second specific space 12, and third specific space 13 can quickly accommodate and guide the water flow, and the condensate is efficiently discharged through the outlet 7 by using gravity and the inertia of the water flow, avoiding water accumulation; when the generation amount decreases, the space structures can still ensure the stable passage of the water flow, maintaining the normal operation of the system and ensuring that the drainage efficiency is not affected by the fluctuations.

[0032] As Figure 1 - Figure 11As shown, a first cylinder wall 11a3 is provided on one side of the inlet 6; a second cylinder wall 11a4 is provided on one side of the first cylinder wall 11a3; a flat wall 11a5 is provided on one side of the second cylinder wall 11a4; the first specific space 11 is provided on one side of the inlet 6 and includes a first space 11a and a second space 11b; the first space 11a is located on the X1 side of the inlet 6 and is adjacent to the inlet 6, and is in a transverse T shape, and is composed of a space 11a1 extending in the X direction and a space 11a2 extending in the Z direction. The space 11a1 extending in the X direction has the inlet 6, and the space 11a2 extending in the Z direction has a first opening 11c opening in the Z2 direction. The first opening 11c is screwed with a first thread groove 11a6 by a thread and is closed by a first detachable part 3. During operation, the condensed water enters the cylindrical space 11a1 surrounded by the first cylinder wall 11a3 from the inlet 6. The first cylinder wall 11a3 restricts the water flow to make it flow stably. Considering the large flow rate of condensed water in a large system, the space 11a1 extending in the X direction has a large length and diameter to initially buffer a large amount of condensed water, reduce the water flow speed, and reduce the impact on subsequent components. Then, the water flow enters the space 11a2 extending in the Z direction surrounded by the second cylinder wall 11a4 and the flat wall 11a5. The first detachable part 3 is tightly screwed with the first thread groove 11a6 by a thread to close the first opening 11c to form a relatively closed space. In this space, the transverse T-shaped structure makes the water flow change direction, increases the water flow path, is conducive to heat exchange and pressure buffering. At the same time, larger particle impurities collide with the wall surface and settle due to inertia when the water flow turns, realizing preliminary filtration. The flat wall 11a5 is perpendicular to the Z direction of the axial direction of the space 11a2 extending in the Z direction, restricting the movement of the sleeve to ensure the stability of the water flow. Through the transverse T-shaped structure of the first space 11a in the first specific space 11, combined with the restraint of the second cylinder wall 11a4 and the restriction of the flat wall 11a5, not only is a large amount of condensed water initially buffered, the water flow speed is reduced, and the impact on subsequent components is reduced, but also preliminary filtration is realized by the turning of the water flow, effectively removing larger particle impurities and reducing the burden on subsequent processing.

[0033] As Figure 1 - Figure 11As shown, the second space 11b is located on the Z1 side of the first space 11a and adjacent to the first space 11a. The first space 11a is connected to the first opening 11c and is a cylindrical space with openings at both ends. Its second opening 11b1 is connected to the first space 11a, and the third opening 11b2 is connected to the second specific space 12. A second thread groove 11b4 is provided on the inner circumference of the third cylinder wall 11b3. A first filter 21 is threadedly connected to the second thread groove 11b4; during operation, the condensed water processed by the first space 11a flows into the second space 11b surrounded by the third cylinder wall 11b3 through the second opening 11b1. The cylindrical structure ensures smooth water flow. The second thread groove 11b4 on the inner circumference of the third cylinder wall 11b3 is tightly screwed with the thread of the first filter 21 to firmly fix the first filter 21. When a large amount of condensed water passes through, the filter screen of the first filter 21 efficiently intercepts impurities such as rust and scale, deeply purifies the condensed water, protects the subsequent flow path and equipment from impurities, prevents blockage and wear, and the first filter 21 can be easily disassembled and installed through the threaded connection part, so that after the large-scale system runs for a long time, the filter can be maintained and replaced in time for possible blockage, ensuring good filtering effect. Through the reasonable connection between the second space 11b and the first space 11a and the cooperation between the thread groove on the inner circumference of the third cylinder wall 11b3 and the first filter 21, the first filter 21 can be firmly installed and efficiently purify the condensed water. At the same time, it ensures that during the long-term operation of the large-scale system, impurities such as rust and scale can always be effectively intercepted, protecting the subsequent flow path and equipment.

[0034] As Figure 1 - Figure 11As shown, the second specific space 12 includes a third space 12a and a fourth space 12b; the third space 12a is located on the Z1 side of the first specific space 11 and is adjacent to the second space 11b, and has a fourth opening 12c on one side, and the fourth opening 12c is communicated with the outside of the body 2, and the thread of the fourth opening 12c is screwed with the third thread groove 12a3 and is closed by the second detachable part 4; a fourth cylinder wall 12a1 is arranged on the side wall of the third space 12a; a right side wall 12a2 is arranged on one side of the fourth cylinder wall 12a1; a first opposing area 12a11 is arranged inside the third space 12a; during operation, the second detachable part 4 is precisely screwed with the third thread groove 12a3 through the thread to close the fourth opening 12c, so that the third space 12a forms a closed and stable space, and a large amount of high-pressure condensed water flowing in from the second space 11b impacts the opposing area 12a11 on the cylinder wall 12a1 that is precisely opposite to the opening 11b2 of the second space 11b at a high speed. The water flow direction changes rapidly, the speed drops sharply, and the pressure is effectively buffered. The opposing area 12a11 adopts special structures such as a concave-convex surface or a diversion groove to further disperse the water flow energy and reduce the impact on the inside of the equipment, adapting to the complex working conditions with a relatively large condensed water pressure in a large system. The right side wall 12a2 is perpendicular to the X direction of the axis of the third space 12a, accurately guiding the water flow to smoothly enter the fourth space 12b. Through this design, the third space 12a of the second specific space 12 closes the fourth opening 12c through the second detachable part 4 to form a stable space, and the first opposing area 12a11 on its fourth cylinder wall 12a1 can effectively buffer the high-pressure condensed water from the second space 11b, change the water flow direction and speed, and reduce the internal impact, adapting to the complex water flow pressure working conditions of a large system.

[0035] As Figure 1 - Figure 11As shown, the fourth space 12b is located on the X1 side of the third space 12a and is adjacent to the third space 12a. The third space 12a is connected to the fourth opening 12c and is a cylindrical space with openings at both ends. Its fifth opening 12b1 is connected to the third space 12a, and the sixth opening 12b2 is connected to the third specific space 13. A fourth thread groove 12b4 is provided on the inner circumference of the fifth cylinder wall 12b3. A second filter 22 is threadedly connected to the fourth thread groove 12b4 through threads. During operation, the condensed water processed by the third space 12a flows into the fourth space 12b surrounded by the fifth cylinder wall 12b3 through the fifth opening 12b1. The cylindrical structure ensures a stable and continuous flow of water. The fourth thread groove 12b4 on the inner circumference of the fifth cylinder wall 12b3 is tightly screwed with the threads of the second filter 22 to firmly fix the second filter 22. The second filter 22 further finely filters the condensed water that has been preliminarily filtered by the first filter 21, effectively removing minute impurities, significantly improving the purity of the condensed water, ensuring that the condensed water entering the third specific space 13 meets the strict requirements of subsequent processing, and meeting the high-standard requirements of large systems for the quality of condensed water. Through the connection design between the fourth space 12b and the third space 12a, and the connection between the thread groove on the inner circumference of the fifth cylinder wall 12b3 and the second filter 22, the second filter 22 can further finely filter the preliminarily filtered condensed water, significantly improving the purity of the condensed water and ensuring that the water quality in the third specific space 13 meets the high-standard requirements of large systems for condensed water.

[0036] As Figure 1 - Figure 11As shown, the third specific space 13 includes a fifth space 13a and a sixth space 13b; the fifth space 13a is located on the X1 side of the second specific space 12 and is adjacent to the fourth space 12b. One side has a seventh opening 13c, and the seventh opening 13c is in communication with the outside of the body 2. The thread of the seventh opening 13c is screwed with the fifth thread groove 13a3 and is closed by the third detachable part 5. The inner side of the fifth space 13a is provided with a sixth cylinder wall 13a1; one side of the sixth cylinder wall 13a1 is provided with a second opposing area 13a11; one side of the second opposing area 13a11 is provided with a bottom wall 13a2. During operation, the third detachable part 5 is tightly screwed with the fifth thread groove 13a3 through the thread to close the seventh opening 13c, so that the fifth space 13a forms a closed space to ensure the stability of the internal water flow environment. A large amount of condensed water flowing in from the fourth space 12b impacts the second opposing area 13a11 on the sixth cylinder wall 13a1 opposite to the opening 12b2 of the fourth space 12b. The water flow velocity and pressure are effectively buffered and regulated again. The unique structure of the second opposing area 13a11 causes the water flow to form a turbulent flow, fully dispersing the energy and reducing the pressure to adapt to the complex and changeable water flow conditions in a large-scale system. The bottom wall 13a2 is perpendicular to the Z direction of the axial direction of the fifth space 13a, effectively restricting the movement of the sleeve, ensuring the stable flow of water in this space and the accurate flow direction. Through this design, the third detachable part 5 of the fifth space 13a in the third specific space 13 closes the seventh opening 13c to ensure the stability of the internal water flow. The second opposing area 13a11 on its sixth cylinder wall 13a1 can buffer and regulate the water flow velocity and pressure again, form a turbulent flow to disperse the energy, and adapt to the complex water flow conditions. At the same time, the bottom wall 13a2 ensures the stable flow direction of the water.

[0037] As Figure 1 - Figure 11As shown, the sixth space 13b is located on the Z2 side of the fifth space 13a and adjacent to the fifth space 13a. The fifth space 13a is connected to the seventh opening 13c and is a cylindrical space with openings at both ends. Its eighth opening 13b1 is connected to the fifth space 13a, and its ninth opening 13b2 is connected to the discharge space 14. The inner circumference of the seventh cylinder wall 13b3 is provided with a sixth thread groove 13b4, and a third filter 23 is arranged inside the sixth thread groove 13b4. During operation, the condensed water processed by the fifth space 13a flows into the sixth space 13b surrounded by the seventh cylinder wall 13b3 through the eighth opening 13b1. The cylindrical structure ensures smooth water flow. The sixth thread groove 13b4 on the inner circumference of the seventh cylinder wall 13b3 is tightly screwed with the threads of the third filter 23 to firmly fix the third filter 23. The third filter 23 performs a final deep filtration on the condensed water to further remove residual tiny impurities, ensuring that the discharged condensed water reaches a higher purity, meeting the discharge requirements and satisfying the stringent standards for drainage water quality in large systems. Through the threaded connection part, the third filter 23 can be conveniently disassembled and installed, facilitating long-term maintenance and timely replacement, and ensuring that the filter is always in the best working state. Through the connection between the sixth space 13b and the fifth space 13a and the cooperation between the thread groove on the inner circumference of the seventh cylinder wall 13b3 and the third filter 23, the third filter 23 can perform a final deep filtration on the condensed water, ensuring that the discharged condensed water reaches a higher purity and satisfying the stringent standards for drainage water quality in large systems.

[0038] As Figure 1 - Figure 11 As shown, the discharge space 14 is located on the Z2 side of the third specific space 13 and adjacent to the sixth space 13b, and has a discharge port 7 that is open in the X1 direction. During operation, the discharge space 14 converges the condensed water that has been processed layer by layer through multiple specific spaces and filters, playing a buffering role. The discharge port 7 is open in the X1 direction, cleverly utilizing gravity and water flow inertia to ensure that the condensed water can be stably and smoothly discharged to the outside of the main body 2, avoiding water accumulation. This fully meets the drainage requirements of large systems and effectively guarantees the continuous and stable operation of the equipment. Through this design, the discharge space 14 plays a buffering role for the condensed water that has been processed layer by layer, combined with the discharge port 7 that is open in the X1 direction, cleverly utilizing gravity and water flow inertia to ensure stable and smooth discharge of the condensed water, avoiding water accumulation, and effectively guaranteeing the continuous and stable operation of large system equipment.

[0039] During operation, the main body 2 serves as the core load-bearing structure. It is made of high-strength metal materials in a box shape. Its spacious internal space can accommodate a large amount of condensed water and provide a stable installation foundation for various components. In a large system, under the drive of the system pressure difference, the condensed water quickly and smoothly enters the main body 2 through the inlet 6 with a pipe diameter adapted to the condensed water generation volume of the large system. The flow path 8 is carefully laid out to guide the condensed water to pass through multiple specific spaces 11 - 13 for treatment in sequence, and finally discharged through the outlet 7. The position and direction of the outlet 7 are precisely planned to be adapted to the external drainage system. Using gravity and the inertia of the water flow, the condensed water is efficiently discharged to avoid water accumulation causing damage to the equipment. The condensed water enters the cylindrical space 11a1 surrounded by the first cylindrical wall 11a3 from the inlet 6. The first cylindrical wall 11a3 restricts the water flow to make it flow stably. Considering the large flow rate of condensed water in the large system, the space 11a1 extending in the X direction has a relatively large length and diameter to initially buffer a large amount of condensed water, reduce the water flow speed, and reduce the impact on subsequent components. Then, the water flow enters the space 11a2 extending in the Z direction surrounded by the second cylindrical wall 11a4 and the flat wall 11a5. The first detachable part 3 is tightly screwed with the first thread groove 11a6 through a thread to close the first opening 11c, forming a relatively closed space. Inside this space, the horizontal T-shaped structure changes the direction of the water flow, increases the water flow path, is conducive to heat exchange and pressure buffering. At the same time, larger particle impurities collide with the wall surface and settle due to inertia when the water flow changes direction, achieving preliminary filtration. The flat wall 11a5 is perpendicular to the Z direction of the axis of the space 11a2 extending in the Z direction, restricting the movement of the sleeve to ensure the stability of the water flow. The condensed water processed by the first space 11a flows into the second space 11b surrounded by the third cylindrical wall 11b3 through the second opening 11b1. The cylindrical structure ensures smooth water flow. The second thread groove 11b4 on the inner circumference of the third cylindrical wall 11b3 is tightly screwed with the thread of the first filter 21 to firmly fix the first filter 21. When a large amount of condensed water passes through, the filter screen of the first filter 21 efficiently intercepts impurities such as rust and scale, deeply purifies the condensed water, protects the subsequent flow path and equipment from impurity damage, and prevents blockage and wear. Through the threaded connection part, the first filter 21 can be easily disassembled and installed to facilitate timely maintenance and replacement in case of possible blockage of the filter after the long-term operation of the large system, ensuring good filtering effect. The second detachable part 4 is precisely screwed with the third thread groove 12a3 through a thread to close the fourth opening 12c, making the third space 12a form a closed and stable space. A large amount of high-pressure condensed water flowing in from the second space 11b impacts the opposing area 12a11 on the cylindrical wall 12a1 that is precisely opposite to the opening 11b2 of the second space 11b at a high speed. The water flow direction changes rapidly, the speed drops sharply, and the pressure is effectively buffered. The opposing area 12a11 adopts special structures such as a concave-convex surface or a diversion groove to further disperse the water flow energy and reduce the impact on the inside of the equipment, adapting to the complex working conditions with relatively high condensed water pressure in the large system.The right side wall 12a2 is perpendicular to the third space 12a in the axial direction X, accurately guiding the water flow to smoothly enter the fourth space 12b. The condensed water processed in the third space 12a flows into the fourth space 12b surrounded by the fifth cylinder wall 12b3 through the fifth opening 12b1. The cylindrical structure ensures a stable and continuous water flow through. The fourth thread groove 12b4 on the inner circumference of the fifth cylinder wall 12b3 is tightly screwed with the thread of the second filter 22, firmly fixing the second filter 22. The second filter 22 performs a secondary fine filtration on the condensed water preliminarily filtered by the first filter 21, effectively removing minute impurities, significantly improving the purity of the condensed water, ensuring that the condensed water entering the third specific space 13 meets the strict requirements for subsequent treatment and satisfies the high standard requirements of the large system for the quality of condensed water. The third detachable part 5 is tightly screwed with the fifth thread groove 13a3 through the thread, closing the seventh opening 13c, making the fifth space 13a a closed space, ensuring a stable internal water flow environment. A large amount of condensed water flowing in from the fourth space 12b impacts the second opposing area 13a11 on the sixth cylinder wall 13a1 opposite to the opening 12b2 of the fourth space 12b. The water flow velocity and pressure are effectively buffered and regulated again. The unique structure of the second opposing area 13a11 causes the water flow to form a turbulent flow, fully dispersing the energy and reducing the pressure, adapting to the complex and changeable water flow conditions in the large system. The bottom wall 13a2 is perpendicular to the fifth space 13a in the axial direction Z, effectively restricting the movement of the sleeve, ensuring a stable water flow in this space with an accurate flow direction. The condensed water processed in the fifth space 13a flows into the sixth space 13b surrounded by the seventh cylinder wall 13b3 through the eighth opening 13b1. The cylindrical structure ensures a smooth water flow through. The sixth thread groove 13b4 on the inner circumference of the seventh cylinder wall 13b3 is tightly screwed with the thread of the third filter 23, firmly fixing the third filter 23. The third filter 23 performs a final deep filtration on the condensed water, further removing residual minute impurities, ensuring that the discharged condensed water reaches a higher purity and meets the discharge requirements, satisfying the stringent standards of the large system for the quality of drained water. Through the threaded connection part, the third filter 23 can be conveniently disassembled and installed, facilitating long-term maintenance and timely replacement, ensuring that the filter is always in the best working condition. The discharge space 14 converges the condensed water that has been processed layer by layer through multiple specific spaces and filters, playing a buffering role. The discharge port 7 is open in the X1 direction, cleverly utilizing gravity and the inertia of the water flow to ensure that the condensed water can be stably and smoothly discharged to the outside of the main body 2, avoiding water accumulation, fully meeting the drainage requirements of the large system, and effectively ensuring the continuous and stable operation of the equipment.
