Description

Technical Field

[0001] This utility model belongs to the field of valve seat technology, specifically relating to a heat-resistant and corrosion-resistant valve seat structure with high sealing performance. Background Technology

[0002] The valve seat is a key component in a valve that works with closing elements (such as valve discs, balls, etc.) to form a seal. Its core function is to block the flow of fluid media while withstanding the impact of pressure, temperature, and corrosive media.

[0003] Existing valve seats are usually fixed inside the valve body and come into direct contact with moving parts (such as valve discs and balls) to form a sealing pair. However, when the valve seat is in use, the large impact force of the device can easily cause large fluctuations in the medium pressure, resulting in poor sealing effect or sealing failure. Therefore, we need to upgrade and modify the existing technology. Utility Model Content

[0004] The purpose of this invention is to provide a heat-resistant and corrosion-resistant valve seat structure with high sealing performance to solve the problems mentioned in the background art.

[0005] To solve the above problems, the following technical solutions are provided:

[0006] A heat-resistant and corrosion-resistant high-sealing valve seat structure is designed, comprising a device body, which includes a retaining ring 1 and a retaining ring 2. A valve body 1 and a valve body 2 are housed within the retaining rings 1 and 2, and both retaining rings 1 and 2 are equipped with connecting buckles. Threaded cylinders are screwed into the valve bodies 1 and 2, with two sets of threaded cylinders, one end of which is connected to valve seat 1 and valve seat 2. Sealing grooves are formed within valve seat 1 and valve seat 2, and sealing rings 2 are also provided within them. Sealing ring 1 is located within the sealing grooves. A valve core is positioned between valve seat 1 and valve seat 2, and a valve stem is connected above the valve core. A connecting rod is inserted into the connecting buckle, and a nut is screwed onto the connecting rod.

[0007] Furthermore, the first and second retaining rings are provided with mounting grooves, and valve stems are inserted into the mounting grooves.

[0008] Furthermore, multiple sets of the plug rods are provided, and elastic pads are movably sleeved on the plug rods.

[0009] Furthermore, the nut is provided in multiple sets, and anti-slip grooves are formed inside the nut, with multiple sets of anti-slip grooves.

[0010] Furthermore, both the first and second retaining rings are provided with retaining plates on their outer walls, and multiple sets of retaining plates are provided.

[0011] Furthermore, both valve body one and valve body two are provided with flanges at one end.
