Description

Technical Field

[0001] The utility model relates to the technical field of electric control valves, in particular to an electric control valve with controllable flow rate. Background Technique

[0002] An electric control valve is an automatic control valve that controls the opening and closing of the valve and the adjustment of the valve position through an electric actuator. It mainly consists of an electric actuator, a valve body, a controller, etc. The electric actuator is responsible for receiving the control signal and driving the valve stem, thereby changing the flow area between the valve core and the valve seat to achieve the purpose of adjusting the flow rate, pressure or temperature.

[0003] During the use of the existing electric control valve, it is connected to the external pipeline through a connecting flange for normal use. However, during the process of tightening the bolts between the connecting flange and the external pipeline, the tightening bolts rely on manual judgment. If too much tightening force is applied, it is easy to cause the phenomenon of thread slipping, affecting the actual tightening effect. Content of the Utility Model

The pressure sensor is threadedly penetrated and connected to the middle of the plugging head and extends into the connecting pipe, and the buzzer is arranged on the outer surface of one end of the pressure sensor.

[0009] Further, the pressure sensor is internally provided with a control end and is electrically connected to the buzzer through a wire.

[0010] Further, a sleeve hole is provided on the outer surface of one end of the pressure sensor, and the buzzer is set to be columnar and one end is damped and extends into the sleeve hole.

[0027] To make the purpose, technical solution, and advantages of the present utility model clearer, the following will further describe in detail the implementation manners of the present utility model with reference to the attached drawings.

[0028] Please refer to Figures 1-3 As shown, this embodiment is an electric control valve with controllable flow rate, including:

[0029] The electric control valve body, which includes a valve seat 11 and a connecting flange 12; the connecting flange 12 is symmetrically and fixedly connected to the end of the valve seat 11;

[0030] The valve seat 11 is the main installation carrier of the electric control valve body. The valve plate provided inside is affected by the rotational force of the servo motor 14 and can control the flow rate. The connecting flange 12 connects the valve seat 11 to the external pipeline;

[0031] The electric control valve body further includes a bracket 13, a servo motor 14, a reducer 15, and a coupling 16;

[0032] The bracket 13 is fixedly connected to the middle part above the outer surface of the valve seat 11, and the servo motor 14 passes through and is connected to the middle part of the upper end of the bracket 13. The reducer 15 is connected to the lower part of the output end of the servo motor 14, and the coupling 16 is connected to the lower part of the output end of the reducer 15 and extends into the valve seat 11;

[0033] The bracket 13 installs the structure of the servo motor 14, applies a rotational force to the valve plate through the servo motor 14 to complete the multi-angle rotation of the valve plate and complete the regulation of the flow rate. The reducer 15 is used for reducing the rotational force, and the coupling 16 connects the valve plate and the reducer 15 and transmits the force;

[0034] The locking prompt part, which includes a connecting pipe 21, a plugging head 22, a pressure sensor 23, and a buzzer 24; the connecting pipe 21 is threadedly connected to one side of the screw hole on the outer edge of the connecting flange 12, and the plugging head 22 is threadedly connected to the inside of one end of the connecting pipe 21. The pressure sensor 23 is threadedly penetrated and connected to the middle of the plugging head 22 and extends into the connecting pipe 21, and the buzzer 24 is arranged inside the outer surface of one end of the pressure sensor 23;

[0035] The connecting pipe 21 installs and structures the plugging head 22, and fixes the pressure sensor 23 through the plugging head 22. After one end of the bolt contacts the pressure sensor 23 during tightening, due to the change in force, the buzzer 24 can be controlled to give a beeping prompt to avoid the bolt from being tightened too much and causing thread slipping;

[0036] The pressure sensor 23 has a built-in control end and is electrically connected to the buzzer 24 through a wire;

[0037] A sleeve hole is provided on the outer surface of one end of the pressure sensor 23, and the buzzer 24 is columnar and one end is damped and extends into the sleeve hole;

[0038] The sleeve hole structurally fixes the buzzer 24. By using a socket connection method, it is beneficial to the disassembly and assembly of the structure;

[0039] Working principle: When connecting the connecting flange 12 to an external pipeline, first install and fix the connecting pipe 21 on one side of the screw hole on the connecting flange 12, and thread the plugging head 22 at one end of the connecting pipe 21. The pressure sensor 23 is threadedly penetrated through the middle of the plugging head 22, and the buzzer 24 is sleeved on the outer surface of one end of the pressure sensor 23;

[0040] At this time, when placing bolts into the screw holes of the connecting flange 12 and the external pipeline and applying a tightening force, during the tightening process, as one end of the bolt continuously moves forward and contacts the pressure sensor 23, the pressure sensor 23 detects a change in force and can give a beeping prompt through the buzzer 24, that is, the bolt is tightened in place. And slightly apply a reverse force to the bolt that is tightened in place. While ensuring tightening, the buzzer 24 can be stopped;

[0041] This solution can avoid applying too much force to the bolt and causing thread slipping, improving the use effect.

[0042] Please refer to Figures 1-3 As shown, in this embodiment, on the basis of the above embodiment, it further includes a limiting part, and the limiting part includes a thread groove 31 and a limiting ring 32;

[0043] The thread grooves 31 are equidistantly opened at the ends of the inner wall and the outer surface of the connecting pipe 21, and the limiting ring 32 is threadedly connected to the outside of the thread groove 31;

[0044] The middle part of the limit ring 32 is equidistantly provided with threaded holes 33 extending into the connecting flange 12;

[0045] The thread groove 31 satisfies the structural fixation between the connecting pipe 21 and the connecting flange 12, which is beneficial to disassembly and assembly. The limit ring 32 is then used in conjunction with the threaded holes 33 to fixedly connect itself to the threaded holes at the thread stripping position of the connecting flange 12;

[0046] Working principle: When the threaded holes of the connecting flange 12 itself are stripped of threads, the connecting pipe 21 can be disassembled in advance and integrally placed into the stripped threaded holes, and the limit ring 32, threaded holes 33, and external screws are used in conjunction to fix its structure;

[0047] Then use an externally matched bolt, and use the connecting pipe 21 in conjunction to replace the original stripped threaded hole to continue the fastening operation on the connecting flange 12 and the external pipeline;

[0048] This solution improves the applicability and functionality of the structure, meets different usage requirements, and improves the usage effect.
