Description

Technical Field

[0001] This utility model relates to the field of gate valve technology, specifically to a stainless steel rising stem signal gate valve. Background Technology

[0002] A gate valve is a gate that opens and closes. The direction of the gate's movement is perpendicular to the direction of the fluid. Gate valves can only be fully open or fully closed; they cannot be used for regulation or throttling. Gate valves achieve sealing through the contact between the valve seat and the gate. Gate valves include non-rising stem gate valves and rising stem gate valves. In a rising stem gate valve, the stem nut is on the valve cover or frame. When opening and closing the gate, the stem is raised or lowered by rotating the stem nut. In a non-rising stem gate valve, the stem nut is inside the valve body and is in direct contact with the medium. When opening and closing the gate, the stem is rotated.

[0003] In the use of rising stem gate valves, threaded stems are mostly used to control the position of the gate. In actual use, the gate can only be fully open or fully closed. As a result, the sensitivity of the gate control is reduced due to the long idle travel distance of the threaded stem during the opening and closing process. Therefore, a stainless steel rising stem signal gate valve is proposed. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the sensitivity of the gate control is reduced due to the long idle stroke of the threaded rod during the opening and closing process of the gate. This invention provides a stainless steel rising rod signal gate valve.

[0028] like Figures 1 to 5As shown, a stainless steel rising rod signal gate valve includes: a fixing block 1, which is open on one side, with a fixing cover 101 at the open end of the fixing block 1; a fixing sleeve 103 and a control disc 104 arranged sequentially on the outside of the fixing cover 101, with the control disc 104 rotating relative to the fixing sleeve 103; multiple connecting pipes 102 arranged on the outside of the fixing block 1, and the connecting pipes 102 communicating with the fixing block 1; a sealing element 3, disposed inside the fixing block 1, used for controlling the on / off state of the connecting pipes 102; and a control element 2, disposed inside the fixing cover 101, used for adjusting the position of the sealing element 3. Specifically, the control element 2 is positioned within the fixing cover 101. During use, the fixed block 1 and the control component 2 work together to control the movement of the sealing component 3. The moving sealing component 3 can control the flow of water inside the connecting pipe 102. The fixed block 1 and the fixed cover 101 guide the sealing component 3 during use, ensuring that the sealing component 3 can move stably inside the fixed block 1. The connecting pipe 102 is distributed on both sides of the fixed block 1, so that it can be connected to the water pipe during use. The fixed block 1 and the fixed cover 101 can be connected by bolts or clips, which facilitates the maintenance and replacement of the sealing component 3 during use.

[0029] like Figures 1 to 5 As shown, the sealing element 3 includes a gate 301, which is disposed inside the fixing block 1 and slides inside the fixing block 1. A receiving groove 302 is provided inside the gate 301, which penetrates one side of the gate 301 and the penetration direction of the receiving groove 302 points to the opening end of the fixing block 1. A connecting groove 304 is provided inside the receiving groove 302, which is connected to the receiving groove 302, and the opening direction of the connecting groove 304 is perpendicular to the opening direction of the receiving groove 302. Specifically, the fixing block 1 can guide the movement direction of the gate 301 during use, ensuring that the gate 301 can stably control the connecting pipe 102. The receiving groove 302 can store the control element 2 during movement, avoiding interference between the gate 301 and the control element 2 during movement, and ensuring the stability of the position of the gate 301 during use.

[0030] like Figures 1 to 5As shown, the control component 2 includes a connecting plate 201 and a threaded rod 204. The connecting plate 201 slides inside the receiving groove 302. Connecting rods 207 are provided at both ends of the connecting plate 201, and the connecting rods 207 correspond one-to-one with the connecting grooves 304, and the connecting rods 207 slide inside the connecting grooves 304. Sliding grooves 205 are provided at both ends of the connecting plate 201, and sliding blocks 206 slide inside the sliding grooves 205. A fixing rod 202 is provided on the outside of the connecting plate 201, and the fixing rod 202 rotates relative to the connecting plate 201. The fixed rod 202 is connected to the fixed cover 101, and the threaded rod 204 passes through the fixed cover 101. The axis of the threaded rod 204 is parallel to the opening direction of the fixed block 1. The threaded rod 204 is screwed to the control panel 104. One end of the threaded rod 204 is provided with a sliding frame 203, which slides inside the fixed rod 202. The sliding block 206 is connected to the sliding frame 203. Specifically, the fixed sleeve 103 can guide the threaded rod 204 during use to ensure the smooth movement of the threaded rod 204. The control panel 104, during use, limits the threaded rod 204 through the cooperation of the sliding frame 203 and the fixed rod 202, preventing the threaded rod 204 from rotating synchronously with the control panel 104. The fixed rod 202 provides support for the connecting plate 201 during use, ensuring the stability of the connecting plate 201's position. The sliding groove 205 guides the sliding block 206 during use, causing the sliding block 206 to rotate the connecting plate 201 and the connecting rod 207 in conjunction with the sliding groove 205. When it is necessary to control the gate 301, the control panel 104 first moves the threaded rod 204, which in turn moves the sliding frame 203 and the sliding block 206. The moving sliding block 206, in conjunction with the sliding groove 205, rotates the connecting plate 201, thereby shortening the length of the threaded rod 204's idle stroke. During the rotation, the connecting plate 201 controls the gate 301 to slide inside the fixed block 1 through the cooperation of the connecting rod 207 and the connecting groove 304.

[0031] like Figures 1 to 5 As shown, a through hole is provided inside the receiving groove 302, and the through hole penetrates the gate plate 301. The axis of the through hole is parallel to the opening direction of the receiving groove 302. Specifically, during use, the water remaining inside the receiving groove 302 is discharged through the through hole to prevent water from remaining inside the receiving groove 302. During the movement of the gate plate 301, the connecting plate 201 and the fixing rod 202 can slide inside the receiving groove 302 to prevent the gate plate 301 from interfering with the fixing rod 202 during the movement.

[0032] like Figures 1 to 5As shown, a groove 303 is also provided inside the receiving groove 302. The groove 303 is connected to the receiving groove 302, and the sliding frame 203 slides inside the groove 303. Specifically, the groove 303 further increases the movement space of the fixing rod 202 inside the gate 301 during use, so as to avoid interference between the fixing rod 202, the sliding frame 203 and the gate 301, and ensure the stability of the gate 301 during movement.

[0033] like Figures 1 to 5 As shown, the threaded rod 204 includes a connecting block and a control rod. The connecting block slides between the fixed rods 202 and is connected to the threaded rod 204. The control rod is connected to the connecting block and the sliding block 206. The control rod is located at both ends of the connecting plate 201. Specifically, the threaded rod 204 and the connecting block can be connected by bolts or clips, thereby limiting the threaded rod 204 during use and preventing the threaded rod 204 from rotating synchronously with the control plate 104. The fixed rod 202 guides the movement direction of the control rod during use, ensuring that the control rod drives the connecting plate 201 to rotate through the cooperation of the sliding block 206 and the sliding groove 205.
