DETAILED DESCRIPTION
[0019] Embodiments of the present utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present utility model, and should not be construed as limitations on the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.
[0020] See also Figure 1-5 The utility model provides an embodiment: a heating universal electric two-way ball valve, comprising a valve body 1, a mounting seat 4 arranged on the valve body 1, and an actuator 2 is installed on the mounting seat 4; after the actuator 2 is inserted into the mounting seat 4 through a connecting seat 6 provided at the bottom thereof, a bolt 9 is provided and then passed through the mounting seat 4 and connected with an internal threaded hole 7 provided on the connecting seat 6, so as to fix the actuator 2 on the valve body 1; a packing gland 8 is also provided on the valve body 1, and is connected to the inner wall surface of the mounting seat 4 through the packing gland 8, so as to compact the packing in the packing cavity.
[0021] In summary, after the mounting seat 4 is connected to the connecting seat 6, the actuator 2 is fixed to the valve body 1 by the bolt 9, so that the stability between the valve body 1 and the actuator 2 is improved, so as to solve the problem that the ball valve cannot work normally due to the shaking of the actuator 2; when the connecting seat 6 is inserted into the mounting seat 4, it is fixed by the bolt 9, so that the connecting seat 6 does not need to be processed with threads, and the mounting seat 4 does not need to be processed with threads or other connection structures, thereby simplifying the connection method between the actuator 2 and the valve body 1, facilitating the replacement of the actuator 2 and reducing the processing cost of the actuator 2. In addition, the packing gland 8 is used to compact the packing in the packing cavity, so that the valve body 1 does not need to use the actuator 2 to compress the packing. To facilitate the replacement of the actuator 2.
[0022] The existing electric two-way valve is basically installed by threading the valve pipe and the water pipe at both ends, and then wrapping waterproof tape around the connection port for sealing. However, when the two-way valve is disassembled for maintenance and then reinstalled, new waterproof tape needs to be wrapped, which wastes resources and is not easy to disassemble and assemble. In order to solve the above problems:
[0023] The two ends of the valve body 1 are also provided with connectors 3; the connector 3 includes a connecting pipe 31 connected to the valve body 1 at one end, and the other end of the connecting pipe 31 is connected to the water pipe. Due to the setting of the connecting pipe 31, the connecting pipe 31 of different forms can be replaced to facilitate the connection of the device with water pipes of different materials. For example, when the water pipe is made of plastic, a connecting pipe 31 of plastic material is selected; when the water pipe is made of metal pipe, the connecting pipe 31 can be made of metal. Based on this, while facilitating the connection between the valve body 1 and the water pipe, the same valve body 1 only needs to replace different connecting pipes 31 to adapt to water pipes of different materials.
[0024] Furthermore, since the connector 3 further includes a fastener 33, which is connected to the valve body 1 via the fastener 33 to fix one end of the connecting pipe 31 on the valve body 1, the installation and replacement of the connecting pipe 31 is facilitated by disassembling and assembling the fastener 33.
[0025] Based on this, the installation and replacement of the connecting pipe 31 can be completed by tightening or loosening the fastener 33, so as to solve the problem in the prior art that the connecting pipe 31 is difficult to disassemble and assemble due to the waterproof tape.
[0026] In order to improve the sealing performance after the connection pipe 31 is connected to the valve body 1, a protrusion 35 extending radially outward along the connection pipe 31 is provided at one end of the connection pipe 31, and the fastener 33 is tightened to cause the protrusion 35 to press against the contact surface 5 provided on the valve body 1. Furthermore, a first sealing ring 30 is provided between the contact surface 5 and the protrusion 35, and a second sealing ring 32 is provided between the valve body 1 and the fastener 33.
[0027] In summary, when the fastener 33 is tightened, the protrusion 35 squeezes the first sealing ring 30 and the second sealing ring 32 at the same time, thereby making the connection between the valve body 1 and the connecting pipe 31 have reliable sealing. At the same time, the provision of the protrusion 35 can also expand the contact area between the connecting pipe 31 and the first sealing ring 30, thereby improving the sealing of the connection between the valve body 1 and the connecting pipe 31.
[0028] In addition, since the connecting tube 31 is provided with ribs 34, and the number of the ribs 34 is multiple and arranged in a circumferential array on the connecting tube 31, the ribs 34 can be used to enhance the structural strength of the connecting tube 31, and the ribs 34 can also be used to expand the contact surface between the connecting tube 31 and the air, so as to improve the heat dissipation capacity of the device.
[0029] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
