Description

Technical Field

[0001] The utility model belongs to the technical field of valves and relates to a valve body, in particular to a novel sealing valve body. Background Art

[0002] The definition of "valve" is a device used to control the direction, pressure, and flow of fluid in a fluid system. A valve is a device that allows the medium (liquid, gas, powder) in pipes and equipment to flow or stop, and can control its flow.

[0003] Among them, the valve body is the core component of fluid control, and its sealing performance directly affects the stability and safety of the entire fluid control system. However, traditional valve body sealing devices have problems such as complex structure, difficult maintenance, and unstable sealing performance, which makes it difficult to meet the requirements of modern industry for high efficiency, energy saving, and environmental protection. Summary of the invention

[0004] The purpose of the utility model is to provide a novel high-efficiency sealing valve body in view of the above problems existing in the prior art.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a new type of sealing valve body, including a valve body, characterized in that the valve body is provided with a water inlet for water intake and a water outlet for water discharge, and the water outlet is connected with a delivery pipe, the delivery pipe is connected to the water outlet through an external thread, the water outlet is provided with a sealing component for sealing the delivery pipe, the sealing component is provided with a double-layer sealing ring, and the double-layer sealing ring is provided with a sealing frame for supporting and protecting the double-layer sealing ring.

[0006] In the above-mentioned novel sealing valve body, the double-layer sealing ring is a two-layer structure, the first layer of the double-layer sealing ring is a soft sealing ring, and the second layer is a hard sealing ring. The soft sealing ring and the hard sealing ring cooperate to improve the sealing effect of the water outlet.

[0007] Compared with the prior art, the new sealing valve body adopts a double-layer sealing structure, which can maintain excellent sealing performance under various complex working conditions; the sealing component has a simple structure, which reduces the manufacturing cost and maintenance difficulty; because the sealing component adopts a combination of soft and hard materials, it can effectively extend the service life of the valve body.

[0012] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0013] like Figure 1 , Figure 2 , Figure 3 As shown, the new sealing valve body 1 includes a valve body 1, and the valve body 1 is provided with a water inlet 2 for water intake and a water outlet 3 for water discharge, and the water outlet 3 is connected to a delivery pipe 4, and the delivery pipe 4 is connected to the water outlet 3 through an external thread 5, and a sealing component 6 for sealing the delivery pipe 4 is provided on the water outlet 3, and the sealing component 6 is installed on the valve body 1 and cooperates with the delivery pipe 4, and a double-layer sealing ring 7 is provided on the sealing component 6, and a sealing frame 8 for supporting and protecting the double-layer sealing ring 7 is provided on the double-layer sealing ring 7, and the sealing frame 8 prevents the double-layer sealing ring 7 from being damaged by external forces.

[0014] To further elaborate, the double-layer sealing ring 7 has a two-layer structure. The first layer of the double-layer sealing ring 7 is a soft sealing ring 9, and the second layer is a hard sealing ring 10. An inner soft sealing ring 9 and an outer hard sealing ring 10 are prepared and assembled into the double-layer sealing ring 7. The soft sealing ring 9 and the hard sealing ring 10 cooperate with each other to improve the sealing effect of the water outlet 3.

[0015] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0016] Although the terms valve body 1, water inlet 2, water outlet 3, delivery pipe 4, external thread 5, sealing assembly 6, double-layer sealing ring 7, sealing frame 8, soft sealing ring 9, hard sealing ring 10 are used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
