Description

Technical Field

[0001] This utility model relates to the field of steam pipeline technology, and in particular to a steam thermal stabilization structure. Background Technology

[0002] A steam generator, also called a steam heat source machine (commonly known as a boiler), is a mechanical device that uses the heat energy of fuel or other energy sources to heat water into hot water or steam. Steam generators have a wide range of applications in various fields. The steam pressure produced by a steam generator is unstable. Therefore, when using steam, a pressure reducing valve needs to be installed at the end of the steam generator's outlet pipe. After the steam passes through the pressure reducing valve, the steam pressure after the valve can be stabilized at the set value, thus facilitating the use of steam.

[0003] When installing existing pressure reducing valves at the end of the steam generator's outlet pipe, a certain gap needs to be left between the beginning of the steam delivery pipeline and the end of the steam generator's outlet pipe. The pressure reducing valve is then placed into this gap, with its inlet connected to the end of the steam generator's outlet pipe via a flange, and its outlet connected to the beginning of the steam delivery pipeline via a flange. To ensure a tight seal at the flange connection, a gasket is required between adjacent flanges. However, because the steam delivery pipeline structure is fixed, the gap width between the beginning of the steam delivery pipeline and the end of the steam generator's outlet pipe must be close to the width of the pressure reducing valve to ensure a tight seal after the flange connection. This leads to the following drawback when installing the pressure reducing valve:

[0004] Because the gap between the beginning of the steam delivery pipeline and the end of the steam generator outlet pipe needs to be close to the width of the pressure reducing valve, it is not easy to put the pressure reducing valve and the sealing gasket into the gap between the beginning of the steam delivery pipeline and the end of the steam generator outlet pipe, making the installation of the pressure reducing valve inconvenient. Utility Model Content

[0005] The purpose of this utility model is to at least solve one of the technical defects described in the background art.

[0006] Therefore, one objective of this utility model is to propose a steam thermal stabilization structure, which aims to solve the problem that pressure reducing valves are not easy to install in existing steam pipelines.

[0007] To achieve the above objectives, one embodiment of the present invention provides a steam thermal stabilization structure, including an outlet pipe, a delivery pipe, and a pressure reducing valve located between the outlet pipe and the delivery pipe. A first limiting ring is fixedly installed at one end of the delivery pipe, and a sleeve is slidably sleeved on the outer surface of the first limiting ring. A second limiting ring is fixedly connected to the inner wall of one end of the sleeve. A first sealing gasket is provided between the first limiting ring and the second limiting ring. Flanges are fixedly connected to the end of the outlet pipe, one end of the sleeve, and the inlet and outlet ends of the pressure reducing valve.

[0008] The beneficial effects are as follows: the sleeve can slide on the surface of the delivery pipe, thus the gap between the outlet pipe and the sleeve can be adjusted. Therefore, when installing the pressure reducing valve, by sliding the sleeve, the gap between the sleeve and the outlet pipe can be made larger than the width of the pressure reducing valve, so that the pressure reducing valve can be easily inserted into the gap between the outlet pipe and the delivery pipe. Then, the pressure reducing valve is first fixed to the end of the outlet pipe by the flange, and then the sleeve is slid so that its end fits against the outlet end of the pressure reducing valve. Then it can be connected and fixed by the flange, thus facilitating the installation of the pressure reducing valve.

[0009] Preferably, one end of the conveying pipe is fixedly connected to a connector, and the first limiting ring is threadedly connected to the outer surface of the connector.

[0010] The beneficial effect is that when assembling the sleeve on the surface of the conveying pipe, after the sleeve is placed on the beginning of the conveying pipe, the first limiting ring is threaded onto the connector head, which can limit the sleeve and facilitate the assembly of the sleeve.

[0011] Preferably, in the above scheme, the outer diameter of the connector is smaller than the outer diameter of the conveying pipe, the outer diameter of the first limiting ring is larger than the outer diameter of the conveying pipe, and the inner diameter of the first sealing gasket is smaller than the outer diameter of the conveying pipe.

[0012] The beneficial effect is that after tightening the first limiting ring, the first limiting ring and the end of the conveying pipe can clamp the first sealing gasket, thereby sealing the gap between the first limiting ring and the connector, thus ensuring the sealing performance of the structure while ensuring easy assembly of the sleeve.

[0013] Preferably, in any of the above embodiments, a second sealing gasket is provided between two adjacent flanges, and a raised ring is fixedly connected to the side of the flange.

[0014] The beneficial effect is that when two adjacent flanges are connected, the raised ring on the side of the flange can be inserted into the second sealing gasket, thus achieving better sealing performance.

[0015] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0025] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] This invention provides a steam thermal stabilization structure.

[0027] Example 1:

[0028] like Figure 1-3 As shown, it includes an outlet pipe 1, a delivery pipe 2, and a pressure reducing valve 3 located between the outlet pipe 1 and the delivery pipe 2. The outlet pipe 1 is connected to the outlet of the steam generator, allowing steam to enter the pressure reducing valve 3 through the outlet pipe 1. The pressure reducing valve regulates the steam pressure to ensure a stable steam pressure discharged from the outlet of the pressure reducing valve 3. A first limiting ring 21 is fixedly installed at one end of the delivery pipe 2. A sleeve 8 is slidably fitted onto the outer surface of the first limiting ring 21. A second limiting ring 81 is fixedly connected to the inner wall of one end of the sleeve 8. The first limiting ring 21 limits the second limiting ring 81, preventing the sleeve 8 from slipping off the surface of the conveying pipe 2. A first sealing gasket 22 is provided between the first limiting ring 21 and the second limiting ring 81 to seal the gap between the first limiting ring 21 and the second limiting ring 81 and prevent steam leakage. The end of the outlet pipe 1, one end of the sleeve 8, and the inlet and outlet ends of the pressure reducing valve 3 are all fixedly connected to flanges 4. The outlet pipe 1, the conveying pipe 2, and the pressure reducing valve 3 are connected through flanges 4.

[0029] Specifically, a pressure gauge 24 is installed on the delivery pipe 2, through which the steam pressure value after being adjusted by the pressure reducing valve 3 can be observed.

[0030] Preferably, a second sealing gasket 5 is provided between two adjacent flanges 4 to seal the gap between the flanges 4, and a raised ring 41 is fixedly connected to the side of the flange 4. The raised ring 41 can be inserted into the second sealing gasket 5, thereby improving the sealing performance.

[0031] The working principle of this utility model is as follows: The gap between the outlet pipe 1 and the delivery pipe 2 is larger than the width of the pressure reducing valve 3. When installing the pressure reducing valve 3, the sleeve 8 slides away from the outlet pipe 1, so that the pressure reducing valve 3 can be easily inserted into the gap between the outlet pipe 1 and the delivery pipe 2. Then, the pressure reducing valve 3 is first fixed to the end of the outlet pipe 1 by the flange 4. Then, the sleeve 8 is slid so that its end fits against the outlet end of the pressure reducing valve 3. Then, it can be connected and fixed by the flange 4.

[0032] Example 2:

[0033] like Figure 4-5 As shown, based on Embodiment 1, one end of the conveying pipe 2 is fixedly connected to a connector 23, and the first limiting ring 21 is threadedly connected to the outer surface of the connector 23. After the sleeve 8 is placed on the beginning end of the conveying pipe 2, the first limiting ring 21 is then threadedly connected to the connector 23 to limit the sleeve 8. This method facilitates the assembly of the sleeve 8.

[0034] like Figure 5As shown, the outer diameter of the connector 23 is smaller than the outer diameter of the conveying pipe 2, the outer diameter of the first limiting ring 21 is larger than the outer diameter of the conveying pipe 2, and the inner diameter of the first sealing gasket 22 is smaller than the outer diameter of the conveying pipe 2. After tightening the first limiting ring 21, the first limiting ring 21 and the end of the conveying pipe 2 can clamp the first sealing gasket 22, thereby sealing the gap between the first limiting ring 21 and the connector 23.

[0035] Example 3:

[0036] like Figure 6 As shown, based on Embodiment 1 or Embodiment 2, a solenoid valve 6 is fixedly installed between the gas outlet pipe 1 and the pressure reducing valve 3. The solenoid valve 6 can remotely control the opening and closing of the steam delivery pipeline. A valve 7 is fixedly installed between the gas outlet pipe 1 and the solenoid valve 6. The valve 7 is manually controlled and is in a normally open state. Only when the solenoid valve 6 is damaged can the valve 7 be closed manually to close the steam delivery pipeline. The solenoid valve 6 and the valve 7 are both fixed by flanges.

[0037] It should be noted that the pressure reducing valve 3, solenoid valve 6 and valve 7 are all prior art and are well known to those skilled in the art. Therefore, this application will not elaborate on their internal structure and working principle.
