[0020] 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, and 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.

[0021] The purpose of this invention is to provide a stress protection device for valves installed in heating pipelines of municipal engineering projects, so as to solve the problems existing in the prior art.

[0022] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1:

[0024] This embodiment provides a stress protection device for valves installed in heating pipelines of municipal engineering projects, such as... Figure 1-3 As shown, the valve body 1 is connected to both the inlet and outlet ends of the valve body 1 via heating pipes 2. A buffer pipe 3 is connected between the inlet end of the valve body 1 and the heating pipe 2. A permeable plate 4 is provided inside the buffer pipe 3 near the valve body 1. A guide post 5 is vertically provided at the center of the permeable plate 4. A buffer mechanism 6 is slidably provided on the guide post 5. A diverter head 7 is provided at the end of the guide post 5.

[0025] As one implementation method, the inlet end of the valve body 1, the end of the heating pipe 2, and both ends of the buffer pipe 3 are provided with connecting flanges, thereby enabling the connection function.

[0026] As one implementation method, a sealing gasket is provided between the connecting flanges to achieve a sealing effect and reduce damage caused by axial stress between pipes.

[0027] As one implementation, the edge of the permeable plate 4 is provided with permeable holes 41 for water to pass through.

[0028] In one embodiment, the guide post 5 has a groove 51 in the middle, and the buffer mechanism 6 is slidably disposed in the groove 51.

[0029] In one embodiment, the buffer mechanism 6 includes a guide plate 61, the diameter of which is smaller than the inner diameter of the buffer pipe 3. The guide plate 61 is sleeved on the outside of the guide post 5, and a slider 62 is provided in its middle. The slider 62 is slidably limited within the groove 51. A buffer spring 63 is provided on the side of the guide plate 61 near the permeable plate 4. After the water flow impacts the diverting head 7, the hemispherical diverting head 7 can disperse the water flow. The dispersed water flow is dispersed after passing through the guide plate 61, and at the same time, the buffer spring 63 plays a buffering role, reducing the impact force.

[0030] In one implementation, the guide plate 61 is provided with a guide groove 64 on the side near the diverter head 7. The guide groove 64 has an arc-shaped dispersed structure to improve the diversion effect.

[0031] As one implementation method, a water distribution groove 31 is provided on the inner wall of the buffer pipe 3 near the valve body 1. The water distribution groove 31 has a spiral structure, and the water flow can flow along the water distribution groove 31, which also plays a buffering role.

[0032] The present invention provides a stress protection device for valve installation in municipal engineering heating pipelines. Its working principle is as follows: when water flows through the heating pipeline 2 to the inlet end of the valve body 1, it first passes through the buffer pipeline 3. After being dispersed by the diverter head 7, the water flows to the guide plate 61. After being dispersed again by the guide plate 61, it flows to the water permeable hole 41 of the permeable plate 4. At the same time, the buffer spring 63 plays a buffering role, reducing the impact force. The dispersed water flows into the valve body 1 under the action of the water distribution trough 31, thereby achieving the effect of reducing stress.

[0033] This invention has illustrated its principles and implementation methods using specific examples. The descriptions of these embodiments are merely illustrative of the method and its core ideas; furthermore, those skilled in the art will recognize that modifications may be made to the specific implementation methods and application scope based on the principles of this invention. Therefore, the content of this specification should not be construed as limiting the invention.
