Description

Technical Field

[0001] This utility model relates to a safety valve, specifically a novel safety valve for steam systems, and belongs to the field of safety valve technology. Background Technology

[0002] Steam, also known as water vapor, is formed when a liquid evaporates in a confined, enclosed space. Liquid molecules pass through the liquid surface and enter the space above, becoming steam molecules. Based on the effects of pressure and temperature on various types of steam, steam is classified into saturated steam and superheated steam. The main uses of steam include heating, humidification, power generation, and propulsion.

[0003] Patent CN206669050U discloses a steam safety valve, relating to the field of safety valve technology. The valve includes a valve body with a first through-hole on its left side. A hollow tube is fixedly connected to the left side of the valve body's inner wall, and a second through-hole is formed in the hollow tube, communicating with the first through-hole. A baffle is fixedly connected to the right side of the hollow tube, and a fixing block is fixedly connected to the right side of the valve body's inner wall. A valve plate is movably connected to the left side of the fixing block via a rotating shaft, with the valve plate located at the top of the baffle. A handle is provided on the left side of the valve body, and a screw is fixedly connected to the right side of the handle. This invention, by incorporating a valve body, a first through-hole, a hollow tube, a second through-hole, a baffle, a fixing block, a valve plate, a handle, and a screw, solves the safety problem that can arise during steam recovery and reuse if blockages occur. This steam safety valve improves the safety of steam recovery and facilitates user operation.

[0004] The aforementioned patent cannot adjust the internal pressure of the steam pipe according to usage requirements. When the internal pressure of the steam pipe is too high, it is necessary to quickly release the internal pressure to prevent excessive pressure from causing an explosion. When the internal pressure is too low, the valve body needs to be closed to prevent pressure loss, which reduces adjustability. When the steam inside the steam pipe is discharged, a large amount of heat is generated, which will cause heat to accumulate inside the valve body. Over time, this will affect the normal use of the valve body, leading to a decrease in safety and a reduction in heat dissipation efficiency. Therefore, a new type of safety valve for steam systems is proposed here. Utility Model Content

[0005] This invention proposes a novel safety valve for steam systems to solve the problem in the prior art that the pressure inside the steam pipe cannot be adjusted according to usage requirements.

[0006] This utility model is achieved through the following technical solution: a new type of safety valve for a steam system, including a steam pipe, a pressure relief component disposed at the top of the steam pipe, and a heat dissipation component disposed outside the pressure relief component;

[0007] The pressure relief assembly includes a valve body, which is fixedly connected to the top of the steam pipe. The valve body has air outlets on both outer sides and a sliding groove on both inner sides. A spring is fixedly connected to the bottom of the inner cavity of the sliding groove, and a slider is fixedly connected to the top of the spring. The slider is slidably connected to the inner cavity of the sliding groove, and a stop block is fixedly connected between the outer sides of the slider.

[0008] Furthermore, the heat dissipation assembly includes an upper heat dissipation ring, which is fixedly connected to the outside of the valve body. A lower heat dissipation ring is fixedly connected to the outside of the valve body. Heat dissipation plates are fixedly connected to the outside of the upper heat dissipation ring and the inside of the lower heat dissipation ring, and are arranged sequentially from left to right.

[0009] Furthermore, a threaded rod is rotatably connected to the top of the inner cavity of the valve body, a movable plate is screwed to the outer side of the threaded rod, and a pressing rod is fixedly connected to both sides of the bottom of the movable plate.

[0010] Furthermore, the threaded rod penetrates the inner cavity of the valve body and extends to the outer side of the valve body. A turntable is fixedly connected to the top end of the threaded rod, and an anti-detachment ring is fixedly connected to the end end of the threaded rod. The turntable is used to drive the threaded rod to rotate, and the anti-detachment ring is used to prevent the movable plate from detaching from the threaded rod.

[0011] Furthermore, the upper heat dissipation ring has a T-shaped structure, and both the upper and lower heat dissipation rings are made of polyurethane material. Polyurethane material has high thermal insulation properties, which can prevent the heat generated by steam discharge from affecting the valve body.

[0012] Furthermore, the heat sink has an arc-shaped structure, and heat dissipation holes are opened on the outer side of the heat sink, arranged sequentially from top to bottom. The heat dissipation holes are used to change the movement trajectory of the steam exhaust to achieve a heat dissipation effect.

[0013] This utility model provides a novel safety valve for steam systems, which has the following beneficial effects:

[0014] 1. The safety valve in this new steam system can be operated by rotating a turntable to drive a threaded rod, which in turn moves a movable plate. The movable plate then moves a pressing rod to press a stop block, blocking the steam outlet and thus regulating the steam discharge rate. This changes the pressure within the steam pipe. When rapid steam discharge is needed, rotating the threaded rod moves the pressing rod upward, causing a spring to push a slider and move the stop block, thereby removing the blockage at the steam outlet and allowing steam to discharge quickly. This prevents excessive pressure from causing the steam pipe to explode and improves adjustability.

[0015] 2. This new type of steam system uses a safety valve to discharge steam through the valve body and the outlet. The discharged steam is guided out through the upper and lower heat dissipation rings, both of which are made of polyurethane material, which has good heat insulation properties and can prevent heat from accumulating in the valve body. By setting heat dissipation plates and heat dissipation holes, the movement trajectory of steam output is changed. The arc-shaped structure of the heat dissipation plate can increase the movement distance of steam discharge, thereby achieving the heat dissipation effect and preventing the safety valve from malfunctioning when heat accumulates, thus improving the heat dissipation efficiency.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0025] Please see Figures 1-5 This utility model provides a novel safety valve for a steam system, including a steam pipe 100, a pressure relief assembly disposed at the top of the steam pipe 100, and a heat dissipation assembly disposed outside the pressure relief assembly;

[0026] Please refer to this carefully. Figures 1-3 The pressure relief assembly includes a valve body 110, which is fixedly connected to the top of the steam pipe 100. Air outlets 111 are opened on both outer sides of the valve body 110. Slide grooves 120 are opened on both inner sides of the valve body 110. A spring 121 is fixedly connected to the bottom of the inner cavity of the slide groove 120, and a slider 122 is fixedly connected to the top of the spring 121. The slider 122 is slidably connected to the inner cavity of the slide groove 120. A stop block 123 is fixedly connected between the outer sides of the slider 122. A threaded rod 130 is rotatably connected to the top of the inner cavity of the valve body 110. A movable plate 131 is screwed to the outer side of the threaded rod 130. A pressing rod 132 is fixedly connected to both bottom sides of the movable plate 131. The threaded rod 130 penetrates the inner cavity of the valve body 110 and extends to the outer side of the valve body 110. The top of the threaded rod 130 is fixedly connected to... The device includes a turntable 133 and an anti-detachment ring 134 fixedly connected to the end of a threaded rod 130. During use, rotating the turntable 133 drives the threaded rod 130 to rotate, which in turn moves the movable plate 131. The movable plate 131 then moves the pressing rod 132 to press the stop block 123, causing the stop block 123 to block the air outlet 111. This regulates the steam discharge rate and thus changes the pressure within the steam pipe 100. When rapid steam discharge is required, rotating the threaded rod 130 moves the pressing rod 132 upward, causing the spring 121 to push the slider 122 to move and move the stop block 123, thereby releasing the blockage of the air outlet 111 and allowing the steam to discharge rapidly. This prevents excessive pressure from causing the steam pipe 100 to explode and improves adjustability.

[0027] Please refer to this carefully. Figure 1 , Figure 4 and Figure 5 The heat dissipation assembly includes an upper heat dissipation ring 200, which is fixedly connected to the outside of the valve body 110. A lower heat dissipation ring 210 is fixedly connected to the outside of the valve body 110. Heat dissipation plates 220 are fixedly connected to the outside of the upper heat dissipation ring 200 and the inside of the lower heat dissipation ring 210, arranged sequentially from left to right. The upper heat dissipation ring 200 has a T-shaped structure. Both the upper heat dissipation ring 200 and the lower heat dissipation ring 210 are made of polyurethane. The heat dissipation plate 220 has an arc-shaped structure. Heat dissipation holes 221 are opened on the outside of the heat dissipation plate 220, arranged sequentially from top to bottom. Steam is discharged through valve body 110 and outlet 111. The discharged steam is guided out by upper heat dissipation ring 200 and lower heat dissipation ring 210. Both upper heat dissipation ring 200 and lower heat dissipation ring 210 are made of polyurethane material, which has good heat insulation properties and can prevent heat from accumulating in valve body 110. The movement trajectory of steam output is changed by setting heat dissipation plate 220 and heat dissipation hole 221. The arc-shaped structure of heat dissipation plate 220 can increase the movement path of steam discharge, thereby achieving the effect of heat dissipation and preventing the safety valve from failing to function properly when heat accumulates, thus improving heat dissipation efficiency.

[0028] In use, this invention can be used by rotating the turntable 133 to drive the threaded rod 130 to rotate, which in turn drives the movable plate 131 to move. The movable plate 131 then drives the pressing rod 132 to move and press the stop block 123, thus blocking the air outlet 111 and adjusting the steam discharge rate. This changes the pressure inside the steam pipe 100. When rapid steam discharge is needed, rotating the threaded rod 130 can drive the pressing rod 132 upward, causing the spring 121 to push the slider 122 to move and drive the stop block 123 to move, thereby removing the blockage of the air outlet 111 and allowing the steam to be discharged quickly, preventing excessive pressure from causing the steam pipe 100 to explode.

[0029] During use, steam is discharged through valve body 110 and outlet 111. The discharged steam is guided out through upper heat dissipation ring 200 and lower heat dissipation ring 210. Both upper heat dissipation ring 200 and lower heat dissipation ring 210 are made of polyurethane material, which has good heat insulation properties and can prevent heat from accumulating in valve body 110. The movement trajectory of steam output is changed by setting heat dissipation plate 220 and heat dissipation hole 221. The arc-shaped structure of heat dissipation plate 220 can increase the movement path of steam discharge, thereby achieving the heat dissipation effect.
