Description

Technical Field

[0001] This utility model relates to the field of valve controller technology, and more specifically, it relates to a remote control type valve actuator. Background Technology

[0002] A valve actuator is a drive device that converts control signals into mechanical displacement. It drives valves to open or close or adjust the opening degree through electric, pneumatic or hydraulic mechanisms, so as to achieve precise control of pipeline medium flow, pressure and temperature. It can also be equipped with additional functions such as position feedback, fault self-diagnosis and handwheel clutch. It is widely used in process industries such as petrochemical, power, building automation and so on.

[0003] Currently, existing valve actuators typically adopt an integrated design, directly controlling the valve body. Among known technologies, there are those that assemble the valve actuator and valve body using a disassembly-friendly structure, allowing for easy replacement and maintenance of either the actuator or the valve body.

[0004] However, valve actuators operate in a variety of environments. In high-temperature environments, electronic components, grease, and seals may age due to temperature resistance issues. In low-temperature environments, the viscosity of the grease increases sharply, and the starting current of the motor increases, leading to difficulty in starting and extended action time. In strong magnetic environments, control failure may occur.

[0005] To address the above problems, this utility model proposes a remote control type valve actuator. Utility Model Content

[0033] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0034] Please see Figure 1-7 The present invention provides the following technical solution:

[0035] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0036] See Figure 1 and Figure 2A remote control type valve actuator includes a valve actuator 1 and a control terminal 2. A socket assembly 3 is installed on both the valve actuator 1 and the control terminal 2. A connection mechanism 4 is fitted on the two socket assemblies 3. A first connection line 5 and a second connection line 6 are connected between the connection mechanism 4 of the valve actuator 1 and the connection mechanism 4 of the control terminal 2.

[0037] Valve actuator 1 transmits valve control signals to control terminal 2. Valve actuator 1 performs corresponding actions according to the action of control terminal 2. Socket assembly 3 is fixed on the mounting positions of valve actuator 1 and control terminal 2 respectively. The control terminal is a machine resistant to extreme working conditions. Socket assembly 3 provides an installation position for connection mechanism 4. First connection line 5 is a positive signal line, marked SIG+, and second connection line 6 is a negative signal line, marked SIG-. First connection line 5 and second connection line 6 provide an AC signal path between valve actuator 1 and control terminal 2.

[0038] The socket assembly 3 includes a socket body 31 and a fixing bolt 32. The socket body 31 has a circularly equidistant fixing groove 36. The fixing bolt 32 passes through the fixing groove 36 and is fixed to the control terminal 2.

[0039] The socket body 31 provides an installation position for easy fitting with the connection mechanism 4. The fixing bolts 32 correspond to the installation positions on the valve actuator 1 and the control end 2, respectively. The socket body 31 is fixed to the valve actuator 1 and the control end 2 by passing the fixing bolts 32 through the fixing grooves 36. The four fixing grooves 36 can prevent the socket body 31 from shifting on the valve actuator 1 or the control end 2, and avoid instability during signal transmission.

[0040] The socket body 31 is provided with an outer fixing groove 33, an inner fixing plug groove 34 and a positioning groove 35 in sequence along the radius towards the middle position. The outer fixing groove 33, the inner fixing plug groove 34 and the positioning groove 35 are all arranged in a circular array along the center.

[0041] The outer fixing groove 33 and the inner fixing insertion groove 34 are inserted into the connecting mechanism 4 to facilitate the connection between the fixed socket assembly 3 and the connecting mechanism 4 and to avoid unstable insertion. Both the outer and inner rings are inserted to increase the friction during actual operation. The positioning groove 35 positions the mating position with the connecting mechanism 4. Since there are many insertion grooves in the outer fixing groove 33 and the inner fixing insertion groove 34, misalignment may occur during insertion. By setting fewer positioning grooves 35 to pre-position the connecting mechanism 4, misalignment during insertion is avoided.

[0042] The connection mechanism 4 includes a connection end 41 and a plug assembly 44 disposed at one end of the connection end 41. The plug assembly 44 is fitted and installed with the socket assembly 3. The connection end 41 is provided with a first plug wire slot 42 and a second plug wire slot 43. A first connecting line 5 is connected between the first plug wire slot 42 of the valve actuator 1 and the first plug wire slot 42 of the control end 2. A second connecting line 6 is connected between the second plug wire slot 43 of the valve actuator 1 and the second plug wire slot 43 of the control end 2.

[0043] The plug assembly 44 cooperates with the socket assembly 3 to position the installation position of the connection mechanism 4. The connecting end 41 is fixed to the tail end of the plug assembly 44. The first plug slot 42 and the second plug slot 43 in the connecting end 41 transmit signals to the plug assembly 44. The plug assembly 44 transmits signals to the socket assembly 3. The socket assembly 3 transmits signals to the control terminal 2, providing a plug-in position for the first plug slot 42 and the second plug slot 43. The control signal output by the valve actuator 1 is transmitted to the control terminal 2 through the first connecting line 5 and the second connecting line 6.

[0044] By installing socket components 3 and connecting mechanisms 4 on valve actuator 1 and control terminal 2 respectively, and installing two plug components 44 in conjunction with two socket components 3 respectively, the control signals of valve actuator 1 are transmitted to control terminal 2 through the first connecting line 5 and the second connecting line 6 between the two connecting mechanisms 4, the effect of remote control of valve actuator is achieved.

[0045] The plug assembly 44 includes a plug body 441, which is plugged into and fixed to the socket body 31. The plug body 441 is provided with an outer fixing connector 442, an inner fixing connector 443, and a positioning connector 444 in sequence from the radius to the center. The outer fixing connector 442, the inner fixing connector 443, and the positioning connector 444 are all arranged in a circular array along the center. The outer fixing connector 442 is inserted into the outer fixing groove 33, the inner fixing connector 443 is inserted into the inner fixing groove 34, and the positioning connector 444 is inserted into the positioning groove 35 to position the plug body 441 and the socket body 31.

[0046] The plug body 441 and the socket body 31 are shaped to fit together. The outer fixing connector 442 fits into the outer fixing groove 33 and is inserted into the outer fixing groove 33. The inner fixing connector 443 fits into the inner fixing groove 34 and is inserted into the inner fixing groove 34. The cooperation between the outer fixing connector 442 and the outer fixing groove 33 and the inner fixing connector 443 and the inner fixing groove 34 increases the friction after insertion. The positioning connector 444 fits into the positioning groove 35 and is inserted into the positioning groove 35 to position the insertion and prevent misalignment.

[0047] In another embodiment, the socket assembly 3 is installed on the control terminal 2, and the plug assembly 44 is installed on the valve actuator 1. The plug assembly 44 is directly fixed to the socket assembly 3, so that the valve actuator 1 and the control terminal 2 are connected together for joint operation. During direct installation, the plug body 441 and the socket body 31 are fitted together. The outer fixing connector 442 is fitted with the outer fixing groove 33 and inserted into the outer fixing groove 33. The inner fixing connector 443 is fitted with the inner fixing groove 34 and inserted into the inner fixing groove 34. The cooperation between the outer fixing connector 442 and the outer fixing groove 33, and the cooperation between the inner fixing connector 443 and the inner fixing groove 34, increases the friction after insertion. The positioning connector 444 is fitted with the positioning groove 35 and inserted into the positioning groove 35. Thus, there is no need for the first connecting line 5 and the second connecting line 6 to transmit signals. The control signal is transmitted directly through the plug-in method.

[0048] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
