Abstract
Description
Technical Field
[0001] The utility model relates to the field of steam valves, and more specifically, to a pressure relief valve. Background Art
[0002] In a steam control system, due to unstable steam supply, the air pressure in the pipeline may suddenly increase, and the high-pressure steam will seriously affect the service life of the pipeline system. Summary of the Utility Model
[0003] Based on this, in order to solve the problem that high-pressure steam affects the service life of the pipeline system, the utility model provides a pressure relief valve, and its specific technical solution is as follows:
[0004] A pressure relief valve, comprising
[0005] A through pipe;
[0006] A buffer structure, the buffer structure includes a plurality of buffer components arranged in sequence, and a plurality of buffer structures are arranged in the through pipe; the buffer structure includes a first partition layer and a second partition layer with conical outer contours, and the first partition layer and the second partition layer are arranged at intervals along the length direction of the through pipe in the through pipe; a first opening is provided at the top of the first partition layer; a second opening is provided at the bottom of the second partition layer.
[0007] In the above pressure relief valve, when high-pressure steam enters the pressure relief valve, the first partition layer and the second partition layer are both conically arranged to achieve a buffering effect and slow down the speed of the steam; after the high-pressure steam passes through the first opening, it passes through the gap between the first partition layer and the second partition layer, and then enters the next adjacent buffer component through the second opening to achieve a buffering effect. This pressure relief valve solves the problem that high-pressure steam affects the service life of the pipeline system.
[0008] Further, a spray head is provided on the buffer structure.
[0009] Further, the spray head is provided on the first partition layer. Brief Description of the Drawings

[0015] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail in combination with its embodiments. It should be understood that the specific implementation methods described here are only used to explain the utility model and do not limit the protection scope of the utility model.
[0016] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.
[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0018] The “first” and “second” mentioned in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.
[0019] like Figure 1-2 As shown, a pressure relief valve in one embodiment of the utility model includes a through pipe 1 and a buffer structure; the buffer structure includes a plurality of buffer components 2 arranged in sequence, and the plurality of buffer structures are all arranged in the through pipe 1; the buffer structure includes a first partition layer 21 and a second partition layer 22, both of which have conical outer contours, and the first partition layer 21 and the second partition layer 22 are arranged in the through pipe 1 at intervals along the length direction of the through pipe 1; a first opening 3 is provided at the top of the first partition layer 21; a second opening 4 is provided at the bottom of the second partition layer 22.
[0020] In the above pressure relief valve, high-pressure steam enters the pressure relief valve. Since both the first partition layer 21 and the second partition layer 22 are conically arranged, a buffering effect is achieved to slow down the speed of the steam. After the high-pressure steam passes through the first opening 3, it passes through the gap between the first partition layer 21 and the second partition layer 22, and then enters the next adjacent buffering component 2 through the second opening 4, achieving a buffering effect. This pressure relief valve solves the problem of the impact of high-pressure steam on the service life of the pipeline system.
[0021] In one of the embodiments, as Figure 1-2 shown, a spray head 5 is provided on the buffering structure; the spray head 5 is provided on the first partition layer 21. In this way, the buffering effect is achieved by the steam spraying out from the spray head 5.
[0022] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
[0023] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
