Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to an improved balancing valve core and a valve having the improved balancing valve core. Background Technology

[0002] A static balancing valve, also known as a balancing valve, manual balancing valve, digital locking balancing valve, or two-position regulating valve, regulates flow by altering the clearance (opening) between the valve core and seat, thereby changing the flow resistance through the valve. Its working principle is simple and effective: by adjusting the distance between the valve core and seat, the flow resistance of the medium is changed, achieving precise flow control. Figure 1 The diagram shows an existing static balancing valve, comprising a valve body 1', a valve cover 2' mounted on the valve body 1', an inlet channel 4' and an outlet channel 5' within the valve body 1', and a valve seat located between the inlet channel 4' and the outlet channel 5'. A valve stem 3' is threaded onto the valve cover 2', and a valve core rod is threaded onto the valve stem 3'. A valve core 6' is located at the other end of the valve core rod. While this meets the usage requirements, the valve core has a flat plate structure. Therefore, when the valve core is used for flow control, the flat plate valve core presses against the valve seat, and the water flow presses against the valve core. The large flow area of ​​the valve core results in a large opening and closing torque, making the valve prone to failure to close completely. Furthermore, the valve core is prone to wobbling under the action of water flow, causing vibration in the pipeline during opening and closing, thus reducing the valve's service life.

[0003] To address this problem, this utility model was developed. Utility Model Content

[0004] Therefore, in view of the above problems, this utility model proposes an improved balancing valve core with a simple structure and convenient opening and closing adjustment, and a valve with the improved balancing valve core.

[0016] A further improvement is that the limiting device includes two limiting blocks, which are fixedly disposed on the periphery of the valve core rod. A limiting channel is opened on the valve cover, and the limiting blocks are slidably disposed within the limiting channel.

[0017] A further improvement is that the sealing device includes a sealing ring, and the valve body has a sealing groove at the position of the valve core body. The sealing ring is located in the sealing groove and between the valve core body and the valve body.

[0026] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0027] refer to Figure 1-6The present invention discloses a valve with an improved balanced valve core, comprising a valve body 1, a valve cover 2 disposed on the valve body 1, an inlet channel 3 and an outlet channel 4 opened on the valve body 1, and a valve seat disposed between the inlet channel 3. A valve stem 5 is disposed on the valve cover 2, and a valve core 6 for sealing the valve seat is disposed on the valve stem 5. The valve core 6 includes a valve core body 61, which is arranged in the form of a piston sleeve. One end of the valve core body 61 is provided with a valve core rod 61 connected to the valve stem 5. The valve cover 2 has a sliding channel 8, and the valve core rod 61 slides through the sliding channel 8. The valve stem 5 is threaded through the valve core rod 61. The valve core rod 61 is symmetrically provided with limiting blocks 611 on its periphery, which allow the valve core rod 61 to slide up and down when the valve stem 5 rotates. The valve cover 2 has... A limiting channel (not shown in the figure) is provided, and the limiting block 611 is slidably disposed in the limiting channel. The other end of the valve core body 61 is provided with a sealing cylinder 63 that seals with the valve seat. A force-saving device is provided between the sealing cylinder 63 and the valve core body 61 to reduce the flow area and thus save the opening and closing force. The force-saving device is: multiple flow holes 64 are opened between the valve core body 61 and the sealing cylinder 63. The valve core body 61 resists the inner wall of the valve body 1. A sealing ring 9 is provided between the valve body 1 and the valve core body 61. A sealing groove 91 is opened at the position of the valve core body 61 in the valve body 1. The sealing ring 9 is disposed in the sealing groove 91 and is located between the valve core body 61 and the valve body 1. The sealing ring 9 is used to ensure the seal between the valve core body 61 and the inner wall of the valve body 1, so that the water flow will not leak from the two.

[0028] In operation, when adjusting or opening / closing the valve, the valve stem 5 rotates, and the valve stem 5 and valve core 61 are threaded together, causing the valve core 61 to slide up and down. This, in turn, causes the valve core body 61 to slide up and down, which in turn causes the sealing cylinder 63 to slide up and down, thus opening and closing the valve seat. This achieves the opening, closing, and adjustment of the valve. During use, because a flow passage is provided between the piston-type valve core body 61 and the sealing cylinder 63, fluid can enter the valve core body 61 and the valve cover 2, preventing all the fluid from impacting the valve core 6. This reduces the flow area of ​​the valve core 6, thereby reducing the pressure on the valve core 6 and reducing the opening and closing torque, making the valve easier to open and close and easier to adjust.

[0029] To prevent the valve core 6 from easily shaking during opening and closing, which could cause internal vibration of the valve, three fixing claws 67 are included. These fixing claws 67 are evenly distributed and fixedly disposed at the bottom of the sealing cylinder 63, and abut against the inside of the valve seat. The fixing claws 67, positioned at the bottom of the sealing cylinder 63 and contacting the valve seat, make the sealing cylinder 63 more stable and less prone to deformation under water flow, thus extending the service life of the valve core 6. Furthermore, the valve core 6 does not deform during opening and closing, thereby reducing turbulence and vibration in the pipeline, further extending the valve's service life.

[0030] In order to facilitate the connection between the sealing cylinder 63 and the valve core body 61, the sealing cylinder 63 is provided with a connecting rod 65, which is threaded through the valve core body 61. A sealing gasket 66 is provided between the sealing cylinder 63 and the valve core body 61 to ensure a sealed connection between the sealing cylinder 63 and the valve core body 61.
