Description

Technical Field

[0001] This utility model relates to the field of gas plug valve manufacturing technology, and in particular to a gas plug valve structure that can provide feedback on the rotation angle. Background Technology

[0002] Gas rotary valves are commonly used control components in gas pipeline systems, used to open or close gas passages.

[0003] Existing gas plug valves are typically operated manually, with the valve's opening and closing state controlled by rotating a handle. However, traditional gas plug valves have the following shortcomings:

[0004] 1. Inability to intuitively display valve opening: Users cannot accurately judge the current degree of valve opening, which can easily lead to inaccurate gas flow control and pose safety hazards.

[0005] 2. Lack of remote monitoring function: Traditional gas plug valves cannot transmit valve status information to a remote monitoring system, which is not conducive to the intelligent management of gas pipeline systems.

[0006] Therefore, how to achieve quantitative display of the rotation angle of the rotary valve core of a gas plug valve has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0007] In view of the above-mentioned defects of the prior art, the present invention provides a gas plug valve structure that can provide feedback on the rotation angle. The purpose is to monitor and provide feedback on the rotation angle of the gas plug valve core in real time, so as to facilitate users to accurately control the gas flow. The rotation angle of the gas plug valve core can be transmitted to a remote monitoring system in the form of an electrical signal to realize the intelligent management of the gas pipeline system.

[0008] To achieve the above objectives, this utility model discloses a gas plug valve structure that can provide feedback on the rotation angle, including a gas plug valve body on which an encoder is provided.

[0009] The rotary valve core of the gas plug valve body, which adjusts the opening of the gas passage, is connected to the input shaft of the encoder via a mechanical transmission chain.

[0010] The encoder outputs a rotation angle based on the rotational motion input from the mechanical transmission chain.

[0011] Preferably, the mechanical transmission chain is a gear drive, a synchronous belt drive, or a worm gear drive.

[0012] Preferably, the encoder transmits the rotation angle to the remote monitoring system in the form of an electrical signal.

[0013] Preferably, the rotation axis of the rotary valve core is arranged parallel to the input shaft, and the rotational motion is transmitted through a first gear and a second gear that mesh with each other.

[0014] More preferably, the first gear includes a gear structure and a cam structure that are coaxially arranged and fixedly connected;

[0015] The cam structure is used to trigger a micro switch disposed on the gas rotary valve body;

[0016] The micro switch is used to send an ignition command signal.

[0017] More preferably, the ignition command signal issued by the micro switch also serves as the reset signal for the encoder.

[0018] The beneficial effects of this utility model are:

[0019] This invention can monitor and provide feedback on the rotation angle of the gas rotary valve core in real time, allowing users to accurately control the gas flow. It can also transmit the rotation angle of the gas rotary valve core to a remote monitoring system in the form of an electrical signal, thereby realizing intelligent management of the gas pipeline system.

[0020] The following will further explain the concept, specific structure and technical effects of this utility model in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of this utility model. Attached Figure Description

[0034] Cam structure 7 is used to trigger micro switch 8 located on the gas rotary valve body;

[0035] Microswitch 8 is used to send ignition command signals.

[0036] In some embodiments, the microswitch 8 sends an ignition command signal, which also serves as a reset signal for the encoder 5.
