Description

Technical Field

[0001] The present invention relates to the technical field of valve cast steel parts, and specifically to a valve cast steel part made of WCB material that is resistant to high temperature and high pressure. Background Art

[0002] A valve is a control component in a fluid transportation system, with functions such as cutoff, regulation, diversion, prevention of backflow, pressure stabilization, flow splitting, or overflow pressure relief. For valves used in fluid control systems, from the simplest stop valve to various valves used in extremely complex automatic control systems, their varieties and specifications are quite numerous. The carbon steel represented by the material WCB has the characteristics of high strength, good wear resistance, and strong plasticity, enabling the valve to withstand high pressure, high temperature, and harsh working environments. Valves made of WCB material are applied in multiple fields.

[0003] Chinese Patent Publication No. CN113324056A discloses a valve cast steel part made of WCB material that is resistant to high temperature and high pressure, including a valve body, a valve cover, and a support column. Both sides of the valve body are provided with water pipe installation ends, and a plurality of threaded holes are opened on the outer periphery of one side of the water pipe installation end. The center end of the top of the valve body is provided with a mounting seat, and strengthening members are fixedly connected to both sides of the mounting seat. The bottoms of the two strengthening members are respectively fixedly connected to the tops of the water pipe installation ends on both sides of the valve body. The top of the valve cover is provided with a mounting plate, the top of the mounting plate is provided with a limiting plate, the top of the support column is provided with a limiting seat, and mounting feet are fixedly connected to both sides of the bottom of the support column.

[0004] However, the existing device has the following problems:

[0005] When in use, the stability is relatively poor. It is connected through a limiting seat provided at the top of the support column. During the flow of high-pressure fluid, due to the large pressure of the high-pressure fluid, the closing and stability after closing of the valve are not good, and it is applied to the on-off of high-pressure fluid, without regulating the flow of low-pressure fluid, and the specific application effect is not good.

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] Please refer to Figures 1 to 8, an embodiment of the present invention provides a WCB material valve steel casting that can withstand high temperature and high pressure. This WCB material valve steel casting applicable to controlling the on / off of high-pressure fluid. In this embodiment, by improving the structure of the valve body, it has the advantages of low-pressure cut-off and stable on / off of high-pressure fluid. Specifically, the above material can be a WCB steel casting. Taking the WCB material valve as an example, as a preferred solution in this embodiment, the WCB material valve is specifically a WCB material valve steel casting that can withstand high temperature and high pressure, and can cut off the flow at low pressure and stably conduct high-pressure fluid.

[0039] Please refer to Figures 1 to 8 , the present invention provides a technical solution: a WCB material valve steel casting that can withstand high temperature and high pressure. This WCB material valve is mainly applied to the scenario of controlling the on / off of high-pressure fluid.

[0040] Inside the body assembly 1, there is a shielding assembly 2. Inside the shielding assembly 2, there is a connection assembly 3. Inside the body assembly 1, there is an opening and closing assembly 4. On top of the opening and closing assembly 4, there is a moving assembly 5.

On the side of the rotating assembly 8, there is a locking assembly 9.

[0041] The body assembly 1 includes a valve body 101. On top of the valve body 101, a valve cover 102 is fixedly installed. Inside the valve cover 102 and the valve body 101, connection bolts 103 are fixedly installed. High-pressure fluid enters the inside of the valve body 101 from one end of the valve body 101, and the valve cover 102 is fixed on top of the valve body 101 using the connection bolts 103, thereby making the use process of the valve steel casting more stable.

[0042] The shielding assembly 2 includes an inclined plate 201 and a connecting ring 202. The side of the inclined plate 201 is fixedly connected to the inside of the valve body 101. The side of the connecting ring 202 is fixedly connected to the inside of the valve body 101. When high-pressure fluid enters the inside of the valve body 101 and impacts the inclined plate 201, at this time, the inclined plate 201 partially blocks the high-pressure fluid to prevent the high-pressure fluid from suddenly impacting and damaging the internal components of the valve body 101.

[0043] The connecting component 3 includes a connecting rod 301. One end of the connecting rod 301 is rotatably connected to the inside of the connecting ring 202.

A connecting block 304 is fixedly connected to the top of the connecting rod 301. The side surface of the connecting block 304 is fitted and connected to the inside of the valve cover 102. By the impact of high-pressure fluid on the disc plate 302 inside the valve body 101, the disc plate 302 can be rotated inside the connecting ring 202, so that the disc plate 302 drives the connecting rod 301 to rotate, and the connecting rod 301 drives the connecting block 304 to rotate inside the valve cover 102. When the fluid pressure is small, at this time, the torsion spring 303 installed on the surface of the connecting rod 301 drives the disc plate 302 to rotate, which can block the fluid from flowing through the valve, thus achieving the effect of low-pressure cut-off. And by observing the connecting block 304 to determine the on-off of the fluid, it is applicable to high-pressure valve cast steel parts and has a better on-off effect on high-pressure fluid.

[0044] The opening and closing component 4 includes a baffle plate 401. The side surface of the baffle plate 401 is slidably connected to the inside of the valve body 101. A rubber pad 402 is fixedly installed on the side surface of the baffle plate 401. A spring 403 is fixedly installed inside the baffle plate 401. A moving block 404 is fixedly installed on the top of the baffle plate 401. By driving the baffle plate 401 inside the valve body 101 to move up and down through the moving block 404, the on-off of the high-pressure fluid is controlled. When the baffle plate 401 moves up, at this time, a group of cooperatively installed baffle plates 401 move to both sides under the push of the spring 403, so that the baffle plate 401 cooperates with the rubber pad 402 fixedly installed on the side surface, enabling the baffle plate 401 to continuously be in close contact and seal with the inside of the valve body 101, and thus making the on-off process of the high-pressure fluid more stable and accurate.

[0045] The moving component 5 includes a rack 501. The bottom of the rack 501 is fixedly connected to the top of the moving block 404. A gear 502 is meshed with the side surface of the rack 501. A transmission shaft 503 is fixedly installed inside the gear 502. By driving the rack 501 to rotate through the gear 502, and since the gear 502 is a semi-gear 502, the movement of the rack 501 is restricted. When the rack 501 moves, it drives the moving block 404 fixed to the bottom to move, thereby controlling the stable on-off of the high-pressure fluid.

[0046] The fixing component 6 includes a fixing shell 601. The bottom of the fixing shell 601 is fixedly installed on the top of the valve body 101. Fixing bolts 602 are fixedly installed inside the valve body 101 and the fixing shell 601. A fixing frame 603 is fixedly installed on the side surface of the fixing shell 601. By using the fixing bolts 602 to fix the fixing shell 601 on the top of the valve body 101, and the gear 502 and the rack 501 are installed inside the fixing shell 601.

[0047] The limit component 7 includes a fixed clamp 701. The side surface of the fixed clamp 701 is fixedly connected to the inside of the fixed housing 601. A rotating clamp 702 is fitted on the side surface of the fixed clamp 701. The side surface of the rotating clamp 702 is fixedly installed at one end of the transmission shaft 503. When the transmission shaft 503 rotates in cooperation with the rotating shaft 801, and the transmission shaft 503 drives the rotating clamp 702 fixed to its side to rotate, thus the fixed clamp 701 limits the rotation of the rotating clamp 702, and further restricts the rotation range of the rotating shaft 801.

[0048] The rotating component 8 includes a rotating shaft 801. One end of the rotating shaft 801 is fixedly installed inside the rotating clamp 702. A turntable 802 is fixedly installed at the other end of the rotating shaft 801. The surface of the rotating shaft 801 is rotatably connected to the inside of the fixed bracket 603. By rotating the turntable 802, the turntable 802 can drive the rotating shaft 801 fixed to its side to rotate, so that the rotating shaft 801 rotates inside the fixed bracket 603. Due to the relatively large flow pressure of the high-pressure fluid, it is more labor-saving and convenient for the turntable 802 to cooperate with the rotating shaft 801 to control the on-off of the high-pressure fluid.

[0049] The locking component 9 includes a locking block 901. The inside of the locking block 901 is fixedly connected to the side surface of the rotating shaft 801. A locking bolt 902 is fixedly installed on the side surface of the locking block 901. A locking clamp 903 is fitted on the side surface of the locking bolt 902. The side surface of the locking clamp 903 is fixedly installed on the side surface of the fixed bracket 603. By means of the locking block 901 fixed to the side of the rotating shaft 801 cooperating with the locking bolt 902, the locking bolt 902 can fixedly install the locking block 901 and the locking clamp 903, so as to lock the rotating shaft 801 after the on-off control of the high-pressure fluid is completed, stabilize the opening and closing of the high-pressure fluid, and further make the use process of the valve cast steel more stable and more suitable for the on-off control of high-pressure fluid.

[0050] In summary, when the valve cast steel made of WCB material with high temperature and high pressure resistance is in use:

[0051] 1. Rotating the turntable 802 can drive the rotating shaft 801 fixed to the side to rotate, so that the rotating shaft 801 rotates inside the fixed frame 603. Due to the relatively large flow pressure of the high-pressure fluid, it is more labor-saving and convenient for the turntable 802 to cooperate with the rotating shaft 801 to control the on-off of the high-pressure fluid. When the transmission shaft 503 rotates in cooperation with the rotating shaft 801, the transmission shaft 503 drives the rotating clamp 702 fixed to the side to rotate, and the fixed clamp 701 limits the rotation of the rotating clamp 702, thereby restricting the rotation range of the rotating shaft 801. The gear 502 drives the rack 501 to rotate. Since the gear 502 is a semi-gear 502, the movement of the rack 501 is restricted. When the rack 501 moves, it drives the moving block 404 fixed to the bottom to move, thereby controlling the stable on-off of the high-pressure fluid;

[0052] 2. Use the fixing bolt 602 to fix the fixing shell 601 on the top of the valve body 101. The gear 502 and the rack 501 are installed inside the fixing shell 601. The moving block 404 drives the baffle 401 inside the valve body 101 to move up and down, thereby controlling the on-off of the high-pressure fluid. When the baffle 401 moves up, a set of cooperating baffles 401 move to both sides under the push of the spring 403, so that the baffle 401 cooperates with the rubber pad 402 fixed to the side, enabling the baffle 401 to continuously and tightly contact and seal inside the valve body 101, and thus making the on-off process of the high-pressure fluid more stable and accurate;

[0053] 3. Through the locking block 901 fixed to the side of the rotating shaft 801 cooperating with the locking bolt 902, the locking bolt 902 can fixedly install the locking block 901 and the locking clamp 903, so as to lock the rotating shaft 801 after the on-off of the high-pressure fluid is controlled, stabilize the opening and closing of the high-pressure fluid, and thus make the use process of the valve steel casting more stable and more suitable for the opening and closing control of high-pressure fluids.

[0054] 4. The high-pressure fluid enters the valve body 101 from one end of the valve body 101, and the valve cover 102 is fixed to the top of the valve body 101 using the connecting bolt 103, making the use process of the valve steel casting more stable. The high-pressure fluid enters the valve body 101 and impacts the inclined plate 201. At this time, the inclined plate 201 partially blocks the high-pressure fluid to prevent the high-pressure fluid from suddenly impacting and damaging the internal components of the valve body 101;

[0055] 5. The high-pressure fluid impacts the disc 302 inside the valve body 101, enabling the disc 302 to rotate inside the connecting ring 202, thereby causing the disc 302 to drive the connecting rod 301 to rotate, and the connecting rod 301 drives the connecting block 304 to rotate inside the valve cover 102. When the fluid pressure is relatively small, the torsion spring 303 installed on the surface of the connecting rod 301 drives the disc 302 to rotate at this time, which can block the fluid from flowing through the valve, thus achieving the effect of low-pressure flow interruption. And by observing the rotation of the connecting block 304 to determine the on-off of the fluid, it is applicable to high-pressure valve castings and has a better on-off effect on high-pressure fluids.
