Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a stainless steel valve casting. Background Art

[0002] Stainless steel castings are a general term for steel castings produced from various stainless steel materials. Stainless steel valves are valves made of stainless steel materials. Valves include stop valves, ball valves, butterfly valves, gate valves, etc., which can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. In the existing technology, most of the stainless steel valve castings are similar in structure to traditional carbon steel valves or cast iron valves. However, due to the characteristics of stainless steel, stainless steel valve castings are widely used in special environments such as high pressure and high corrosion.

[0003] When the stop valve is in use, when the stop valve is in a closed state, the medium pressure in the pipeline will exert a certain pressure on the valve, so that the valve is tightly pressed against the valve seat, so that a force greater than the medium pressure is required to open the valve when opening it, thereby increasing the difficulty of opening the stop valve. For this purpose, a stainless steel valve casting is proposed. Utility Model Content

[0032] like Figures 1 to 6 As shown, a stainless steel valve casting comprises: a fixed shell 1, a liquid inlet pipe 101 and a liquid outlet pipe 102 are respectively arranged on the outside of the fixed shell 1, the liquid inlet pipe 101 and the liquid outlet pipe 102 are respectively connected to the fixed shell 1, a fixed block 105 is arranged on the outside of the fixed shell 1, a partition 103 is arranged inside the fixed shell 1, and a connecting pipe 104 is arranged in the middle of the partition 103; a sealing component 4 is arranged inside the connecting pipe 104, and is used to control the interruption of water flow; a pressure relief component 5 is arranged inside the sealing component 4, and is used to balance the water pressure; a control component 2 is arranged inside the fixed block 105, and is used to control the sealing component 4. Specifically, when in use, the interruption of water flow is controlled by the sealing component 4 in cooperation with the fixed shell 1. When the water flow needs to flow, the pressure on both sides of the sealing component 4 is balanced by the pressure relief component 5, so that the pressure on both sides is uniform, and the resistance when the sealing component 4 is opened is reduced. When the flow needs to be controlled, the position of the pressure relief component 5 and the sealing component 4 is adjusted to improve the effect of water flow regulation.

[0033] like Figures 1 to 6 As shown, the sealing component 4 includes a sealing disk 401, a sealing disk 401, and the sealing disk 401 is abutted against one end of the connecting tube 104. The sealing disk 401 is respectively provided with a rotating groove 404, a sliding groove 405 and a through hole 402. The through hole 402 and the sliding groove 405 are multiple and are opened in the sealing disk 401, and the through hole 402 passes through the groove 403, and the groove 403 corresponds to the sliding groove 405. Specifically, when in use, the position of the sealing disk 401 relative to the connecting tube 104 is changed by the control component 2 to control the water flow. When the sealing disk 401 is in contact with the connecting tube 104, the sealing disk 401 seals the connecting tube 104 to cut off the water flow. When the sealing disk 401 is separated from the connecting tube 104, the side sealing disk 401 conducts the water flow to allow the water flow to flow.

[0034] like Figures 1 to 6As shown, the pressure relief assembly 5 includes a control disk 501, a guide rod 504 and a sealing block 503, the guide rod 504 and the sealing block 503 correspond to the sliding groove 405, the control disk 501 is provided with a guide hole 505 and an arc groove 502, respectively, and the guide hole 505 and the arc groove 502 both penetrate the control disk 501, the guide rod 504 slides inside the arc groove 502, the sealing block 503 slides inside the sliding groove 405, and the control disk 501 rotates inside the rotating groove 404, specifically, the arc groove 502 is in an arc shape, and the center of the arc groove 502 is aligned with the control disk The centers of the circles 501 are staggered, so that when the control disk 501 rotates, the sealing block 503 is pushed to move through the cooperation of the arc groove 502 and the guide rod 504, thereby achieving the balance of water flow pressure on both sides of the sealing disk 401, and at the same time, the flow rate of the water flow can be controlled. When the sealing block 503 and the guide rod 504 move, the sealing block 503 is guided by the sliding groove 405 to ensure the stability of the sealing block 503. The two sides of the control disk 501 are connected through the guide hole 505 to avoid the control disk 501 blocking the water flow when the water flows through the through hole 402.

[0035] More specifically, when water flow is required, the control disk 501 is first driven to rotate through the control component 2. During the rotation of the control disk 501, the guide rod 504 and the sealing block 503 are pushed to move inside the through hole 402 through the arc groove 502, so that water flows out from the through hole 402, so as to balance the pressure on both sides of the sealing disk 401, and facilitate the adjustment of the position of the sealing disk 401 relative to the connecting pipe 104. At the same time, the flow rate of water is accurately controlled by controlling the moving distance of the sealing block 503 in the sliding groove 405 to ensure that it can meet the needs during use.

[0036] like Figures 1 to 6 As shown, the control component 2 includes a rotating sleeve 201 and a rotating rod 204, one end of the rotating sleeve 201 and the rotating rod 204 are respectively connected to the sealing disk 401 and the control disk 501, and the rotating rod 204 rotates inside the rotating sleeve 201, and an external thread is provided on the outer side of the other end of the rotating sleeve 201, and the external thread is threadedly connected to the fixed block 105. Specifically, when in use, the sealing disk 401 is driven to move linearly relative to the connecting pipe 104 by rotating the rotating sleeve 201, so as to control the on-off of the water flow on both sides of the sealing disk 401. The rotating rod 204 inside the rotating sleeve 201 is connected to the control disk 501, so that when in use, the rotating rod 204 can be used to control the disk 501 to rotate, thereby adjusting the position of the sealing block 503 to control the flow of water.

[0037] like Figures 1 to 6As shown, a connecting groove 202 is opened at the other end of the rotating rod 204, and a limiting groove is opened inside the connecting groove 202. The limiting groove is slidably connected to the limiting strip, and a sliding rod 203 is arranged between the limiting strips. Specifically, through the cooperation of the limiting groove and the limiting strip, the sliding rod 203 can rotate synchronously relative to the rotating rod 204, and the sliding rod 203 can slide inside the connecting groove 202, so that the connecting groove 202 can store the sliding rod 203 after the adjustment is completed, so as to avoid accidentally touching the sliding rod 203 during use and causing the rotating rod 204 to rotate, thereby ensuring the stability of the water flow rate.

[0038] like Figures 1 to 6 As shown, the sealing disk 401 is provided with a groove 403 relative to one end of the connecting tube 104, and a sealing strip is provided inside the groove 403. The sealing strip abuts against the end of the connecting tube 104. Specifically, the sealing strip is made of rubber material, so that when the sealing disk 401 is connected to the connecting tube 104, the gap between the sealing disk 401 and the connecting tube 104 is sealed to prevent water from leaking through the gap between the sealing disk 401 and the connecting tube 104, thereby ensuring stability during use.
