[0034] like Figures 1-5 The diagram shows an actuator connection structure for a heat-resistant polyethylene balancing valve disclosed in this utility model, comprising:
[0035] Mounting base 1, the actuator body 3 is fixedly connected to the balance valve, and the mounting base 1 has a through shaft hole in the middle, the shaft hole of the mounting base 1 is coaxial with the balance valve shaft;
[0036] The connecting shaft 4 is adapted to the shape and size of the shaft hole, and one end of the connecting shaft 4 is provided with a shaft groove 5 adapted to the balance valve shaft, and the other end of the connecting shaft 4 is provided with a convex shaft 6 adapted to the valve stem of the actuator body 3.
[0037] Connector 7, which is a ring structure, is fixedly connected to actuator body 3 by bolt assembly;
[0038] The fixing component 9 is used to fix the connecting member 7 to the mounting base 1. The convex shaft 6 of the connecting shaft 4 passes through the connecting member 7 and is coaxially connected to the valve stem of the actuator body 3.
[0039] The aforementioned mounting base 1 can be made of the same PE material as the heat-resistant polyethylene balance valve, and the fixed connection between the mounting base 1 and the balance valve can be hot-melt welding. The mounting base 1 is fixed to the balance valve body 2 by hot-melt welding. The mounting base 1 is a hollow tubular structure. When the mounting base 1 is fixed to the balance valve body 2, the valve stem of the balance valve passes through the shaft hole in the middle of the mounting base 1. The mounting base 1 serves as the mounting base of the actuator body 3.
[0040] The connector 7 is fixed to the actuator body 3 by bolt assembly, and then connected to the mounting base 1 by the fixing component 9 on the connector 7, thereby fixing the mounting base 1 and the connector 7, and thus realizing the connection between the actuator body 3 and the balance valve.
[0041] In a further embodiment, the bolt assembly includes a plurality of second screws 8, and the connector 7 is fixedly connected to the actuator body 3 by the second screws 8.
[0042] The connector 7 has an annular structure and is fixed to the actuator body 3. The annular hole of the connector 7 corresponds to the valve stem of the actuator body 3. The connector 7 is specifically connected to the actuator body 3 by attaching the top of the connector 7 to the bottom of the actuator body 3. Then, multiple second screws 8 are set at the bottom of the connector 7. The second screws 8 penetrate the connector 7 and are fixed to the actuator body 3, thereby fixing the connector 7 and the actuator body 3 as one unit. In order to ensure the stability of the connection between the connector 7 and the actuator body 3, multiple second screws 8 are set, generally 3-4, and the multiple second screws 8 are distributed in a circumferential array.
[0043] In a further embodiment, the fixing component 9 includes an annular mounting groove 91 adapted to the connecting ring, which is opened on the top of the mounting base 1, and a slot 92 is opened at the bottom of the mounting groove 91. A locking block 93 is fixedly connected to the bottom of the connector 7, and the shape of the locking block 93 is adapted to the shape of the slot 92. A first screw 94 is provided on the side wall of the mounting base 1. The first screw 94 passes through the side wall of the mounting base 1 and is placed in the slot 92. A screw hole adapted to the first screw 94 is opened on the locking block 93. The locking block 93 on the connector 7 is fixed in the slot 92 on the mounting base 1 by the first screw 94.
[0044] In this embodiment, the fixing component 9 is specifically configured as follows: an annular mounting groove 91 is formed on the top of the mounting base 1. The mounting groove 91 is concentric with the shaft hole. The maximum diameter of the mounting groove 91 is smaller than the outer diameter of the mounting base 1, and the maximum diameter of the mounting groove 91 is adapted to the outer diameter of the connector 7. The inner diameter of the connector 7 is adapted to the inner diameter of the mounting base 1, so that the connector 7 can be completely placed in the mounting groove 91. At the same time, multiple slots 92 are formed along the axial direction of the mounting base 1 in the mounting groove 91, and multiple locking blocks 93 are provided at the bottom of the connector 7. The number of locking blocks 93 is no more than [number missing]. The number of slots 92 is such that the size of the block 93 is adapted to the size of the slot 92. When the connector 7 is fully inserted into the mounting slot 91, the block 93 is placed in the slot 92. A first screw 94 is provided on the side wall of the mounting base 1, extending from the outside into the slot 92. At the same time, a screw hole adapted to the first screw 94 is provided on the block 93. The first screw 94 can be rotated to insert into the screw hole on the block 93, thereby fixing the block 93 to the slot 92 and preventing the block 93 from coming out of the slot 92, thus completing the fixing of the connector 7 and the mounting base 1.
[0045] Additionally, a connecting shaft 4 for connecting the balance valve stem and the actuator body 3 is provided in the shaft hole in the middle of the mounting base 1. The shaft size of the connecting shaft 4 is less than or equal to the shaft hole size of the mounting base 1, and the shaft hole can meet the conditions for shaft rotation. The connecting shaft 4 can be a cylindrical or prismatic structure. When the connecting shaft 4 is a prismatic structure, the outer circle size of the connecting shaft 4 must be less than or equal to the size of the shaft hole. The connecting shaft 4 is placed in the shaft hole of the mounting base 1. A shaft groove 5 adapted to the size of the balance valve stem is opened at the bottom of the shaft body of the connecting shaft 4. Both the shaft groove 5 and the valve stem are square structures. When the valve stem is inserted into the shaft groove 5, the two can rotate synchronously. A square convex shaft 6 is provided at the top of the shaft body of the connecting shaft 4 along its length direction. The convex shaft 6 is adapted to the groove on the valve stem of the actuator body 3 and can be inserted into the groove on the valve stem of the actuator body 3. The balance valve stem and the actuator body 3 valve stem are connected into a rotating whole by the connecting shaft 4, so that the actuator body 3 can drive the balance valve stem to rotate through the connecting shaft 4.
[0046] Furthermore, for ease of installation, multiple slots 92 are provided, and the multiple slots 92 are distributed in a circular array along the circumference of the annular mounting groove 91;
[0047] The number of card blocks 93 and card slots 92 are matched, and the card blocks 93 are distributed in a circular array along the annular connector 7.
[0048] In another embodiment, the bottom of the mounting base 1 is provided with an overflow groove 10, the inner diameter of the overflow groove 10 being larger than the inner diameter of the mounting base 1 and smaller than the outer diameter of the mounting base 1.
[0049] By using the overflow groove 10 at the bottom of the mounting base 1, it is ensured that no material overflows after the actuator body 3 mounting base 1 is welded to the balance valve, thus ensuring the aesthetics of the weld.
[0050] This utility model achieves a reliable connection between the mounting base 1 and the valve body 2 by using the same PE material as the valve body 2 of the actuator body 3 and connecting them to the valve body 2 through hot melt welding.
[0051] The actuator body 3 mounting base 1 has a square groove that mates with a square protrusion on the actuator body 3 connector 7, serving to withstand the torque of the actuator body 3. The connecting shaft 4 connects the actuator body 3 shaft to the balance valve shaft, transmitting torque. This enables a quick connection between the actuator body 3 and the balance valve, ensuring reliable connection.
[0052] The above specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.
[0053] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
