Description

Technical Field

[0001] This utility model relates to the field of regulating valve technology, specifically a high-sealing electric V-type regulating valve. Background Technology

[0002] The electric V-type regulating valve is a rotary ball valve with a metal or metal-to-PTFE sealing core and seat. It combines the best control characteristics of ball valves and butterfly valves into one, and can be used as a control valve or a shut-off valve.

[0003] In practical use, existing electric V-type control valves are difficult to seal due to their V-shaped valve core structure, and leakage is prone to occur when the pipeline pressure is high. Therefore, we propose a high-sealing electric V-type control valve. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A high-sealing electric V-type regulating valve includes: a valve body assembly and a buffer assembly disposed on the valve body assembly. The valve body assembly includes a valve tube, a control motor mounted on the valve tube, a drive rod fixed to the end of the control motor, and a valve core connected to the drive rod. The buffer assembly includes a limiting connector fixed to the end of the drive rod, limiting grooves opened in the valve tube and located at both ends of the valve core, a connecting plate snapped into the limiting grooves and connected to the valve core, a slot opened in the connecting plate for the limiting connector to be inserted, a reset block fixed to one side of the limiting grooves, a feed hole opened in the valve core, a storage hole connected to the inner end of the feed hole, a sealing strip disposed on the outside of the storage hole, and a sealing edge fixed in the valve tube.

[0007] In a preferred embodiment, the present invention can be further configured such that both the limiting connector and the slot adopt a polygonal structure, and the length of the slot is greater than the width of the limiting connector.

[0008] In a preferred embodiment, the present invention can be further configured such that the reset block adopts an elastic rubber strip structure.

[0009] In a preferred embodiment, the present invention can be further configured such that the feed port is positioned toward the middle of the valve tube.

[0010] In a preferred embodiment, the present invention can be further configured such that a magnetic strip is provided at the bottom of the card slot.

[0011] In a preferred embodiment, the present invention can be further configured such that the sealing edge adopts an arc-shaped strip structure and is located on the outside of the sealing strip.

[0012] The above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0013] This invention, through a buffer assembly, allows the medium to enter the storage hole from the feed hole during operation, thereby squeezing the sealing strip towards the sealing edge. This, in conjunction with the sealing edge, improves the sealing performance between the valve core and the valve pipe. The higher the pressure inside the pipeline, the better the sealing performance. Simultaneously, the greater the pressure, the more the connecting plate is pushed towards the reset block, causing the valve core to move appropriately towards the sealing edge. This further enhances the on / off sealing performance in conjunction with the sealing strip and the sealing edge. This solution, through multiple seals, greatly improves the sealing effect of the regulating valve. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0022] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a high-sealing electric V-type regulating valve.

[0023] Combination Figure 1-4As shown, the present invention provides a high-sealing electric V-type regulating valve, comprising: a valve body assembly 100 and a buffer assembly 200 disposed on the valve body assembly 100. The valve body assembly 100 includes a valve pipe 110, a control motor 120 mounted on the valve pipe 110, a drive rod 130 fixed to the end of the control motor 120, and a valve core 140 connected to the drive rod 130.

[0024] The buffer assembly 200 includes a limiting connector 210 fixed to the end of the drive rod 130, a limiting groove 220 opened in the valve tube 110 and located at both ends of the valve core 140, a connecting plate 230 clamped in the limiting groove 220 and connected to the valve core 140, a slot 240 opened in the connecting plate 230 for the limiting connector 210 to be inserted, a reset block 250 fixed to one side of the limiting groove 220, a feed hole 260 opened on the valve core 140, a storage hole 270 connected to the inner end of the feed hole 260, a sealing strip 280 disposed on the outside of the storage hole 270, and a fixed to the end of the valve core 140. The sealing edge 290 inside the valve tube 110, through the buffer assembly 200, allows the medium to enter the storage hole 270 from the feed hole 260 during operation, thereby squeezing the sealing strip 280 towards the sealing edge 290. This, in conjunction with the sealing edge 290, improves the sealing performance between the valve core 140 and the valve tube 110. The higher the pressure inside the pipeline, the better the sealing performance. At the same time, the greater the pressure, the more it pushes the connecting plate 230 towards the reset block 250, thereby causing the valve core 140 to move appropriately towards the sealing edge 290. This further enhances the on / off sealing performance in conjunction with the sealing strip 280 and the sealing edge 290. This scheme, through multiple seals, greatly improves the sealing effect of the regulating valve.

[0025] Specifically, both the limiting connector 210 and the slot 240 adopt a polygonal structure, and the length of the slot 240 is greater than the width of the limiting connector 210. The polygonal structure allows the limiting connector 210 to move within the slot 240. After the pressure in the valve pipe 110 decreases, the limiting connector 210 will reset under the action of the reset block 250, thereby facilitating the control of the drive rod 130 connected to the motor 120 to drive the valve core 140 to rotate and adjust the opening and closing of the valve pipe 110.

[0026] Furthermore, the reset block 250 adopts an elastic rubber strip structure, which has a better elastic effect. Compared with the use of traditional springs, it can prevent the medium residue in the valve tube 110 and facilitate cleaning.

[0027] On the other hand, the feed hole 260 is positioned towards the middle of the valve tube 110, which allows the medium in the valve tube 110 to enter the feed hole 260 better during operation, thereby ensuring the stability of the sealing strip 280 under the thrust and ensuring the sealing effect.

[0028] Furthermore, a magnetic strip 241 is provided at the bottom of the card slot 240. The magnetic strip 241 can magnetically attract and limit the connector 210, which can promote the reset of the connector plate 230 and has high practicality.

[0029] It should be noted that the sealing edge 290 adopts an arc-shaped strip structure, and the sealing edge 290 is located on the outside of the sealing strip 280. It can adhere tightly to the sealing edge 290 after the sealing strip 280 is subjected to thrust, thus ensuring the sealing effect.

[0030] The working principle and usage process of this utility model are as follows: First, during the blocking operation, the control motor 120 drives the valve core 140 to rotate, and then the medium enters the storage hole 270 through the feed hole 260, thereby squeezing the sealing strip 280 towards the sealing edge 290. The sealing edge 290, together with the sealing edge 290, improves the sealing performance between the valve core 140 and the valve pipe 110. The greater the pressure in the pipeline, the better the sealing performance. At the same time, the greater pressure will push the connecting plate 230 towards the reset block 250, thereby causing the valve core 140 to move appropriately towards the sealing edge 290. This further improves the sealing performance of the opening and closing by cooperating with the sealing strip 280 and the sealing edge 290. When the pressure in the valve pipe 110 decreases, the connecting plate 230 will be reset under the action of the reset block 250 and the magnetic strip 241.

[0031] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
