Description

Technical Field

[0001] The utility model relates to the technical field of motor valves, in particular to a motor valve capable of simultaneously collecting upstream and downstream parameters of a pipeline. Background Art

[0002] Motor valves are used in gas meters or gas safety valves to realize the opening or closing control between the upstream and downstream of the gas pipeline. Generally, the motor valve includes a valve housing, a motor, a drive mechanism and a sealing structure.

In the currently disclosed motor valves, the motor in the motor valve is controlled to open or close, and whether it is fully closed is detected. However, the difference in parameters such as pressure or temperature between the upstream and downstream gas pipelines caused by passing through the sealing part is not collected and applied to the opening or closing control of the motor valve.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] See also Figure 1-Figure 5 As shown, in an embodiment of the present invention, a motor valve for simultaneously collecting upstream and downstream parameters of a pipeline is proposed, including a valve body. The valve body can adopt an existing structure, mainly to generate an action to realize the opening and closing control of the upstream and downstream of the gas pipeline. In order to be able to collect the gas parameters of the upstream and downstream for application, such as controlling opening and closing or flow, etc., a fixed bracket 1 is specifically installed on the valve body, and the fixed bracket 1 is provided with an upstream end and a downstream end. The fixed bracket 1 is provided with at least one flow port 105 connecting the upstream end and the downstream end. The valve body is used to close or open the flow port 105. By setting the number and size of the openings of the flow port 105, the gas parameters at the upstream and downstream ends can be different, such as air pressure, temperature, etc., and it is convenient to cooperate with the valve body to achieve more sensitive opening and closing control. The specific number and size of the openings of the flow port 105 are designed according to actual circulation needs, and the specific number is not limited. In order to facilitate sealing, a concave structure can be formed at the position where the flow port 105 is opened. The flow hole can be a circular hole or a non-circular hole, and the specific structure of the fixing bracket 1 is not limited.

[0030] Specifically, a PCB board 406 is installed on the fixed bracket 1, and a first sensor 401 and a second sensor 407 are integrated on the PCB board 406. The first sensor 401 is used to detect the first gas parameter at the upstream end, and the second sensor 407 is used to detect the second gas parameter at the downstream end. After the flow port 105 is set through the fixed bracket 1, the upstream gas needs to pass through the flow port 105 to flow to the downstream. The upstream and downstream are separated by the fixed bracket 1. The first gas parameter is detected at the upstream end by the first sensor 401, and the second gas parameter is detected at the downstream end by the second sensor 407. The collected signals are output to the outside through the soft cable, which can realize parameter monitoring, opening and closing control, etc. of the gas in the gas pipeline at the upstream and downstream ends, providing more functionality.

[0031] Specifically, the first gas parameter and the second gas parameter can be parameters such as air pressure or temperature, and of course can also be other parameters. Therefore, the number and detection type of the first sensor 401 and the second sensor 407 can also be used according to actual detection requirements.

[0032] Specifically, the first sensor 401 and the second sensor 407 for detecting the upstream and downstream ends need to be separated, thus requiring sealing. Specifically, a collection port 108 connecting to the downstream end is provided on the fixed bracket 1. The second sensor 407 is configured to extend into the collection port 108. The PCB board 406 forms a seal with the sealing groove 104 on the fixed bracket 1 via the sealing ring 3, thereby isolating the upstream and downstream ends. When the valve port seal 6 in the valve body is closed, gas from the upstream end cannot enter the downstream end through the flow port 5. Furthermore, after the collection port 108 is sealed, gas from the upstream end cannot flow through the collection port 108 to the downstream end, thus achieving a seal. This results in a better isolation, and the upstream and downstream detection parameters are relatively independent and accurate.

[0033] In order to improve the sealing effect, a first sealing groove 104 concentric with the collection port 108 is opened on the fixing bracket 1. A sealing ring 3 is provided in the first sealing groove 104 to cooperate with the PCB board 406 to achieve sealing isolation between the upstream and downstream ends. The sealing ring 3 can be an O-ring or a sealing gasket.

[0034] At the same time, a breathable film is attached to the first sensor 401, the collection port 108 or the second sensor 407, which can achieve breathability and provide certain waterproof and dustproof protection for the first sensor and the second sensor 407.

[0035] In order to facilitate installation of the PCB board 406 on one side and integration of the first sensor 401 and the second sensor 407 and to ensure separation and sealing, the first sensor 401 and the second sensor 407 are respectively arranged on the front and back sides of the PCB board 406 .

[0036] The collected relevant parameters need to be transmitted externally, and are also integrated through the PCB board 406 for signal transmission. Specifically, the PCB board 406 is integrated with a connection socket 403, and the connection socket 403 is connected to the flexible flat cable 5. Signal transmission is achieved through the flexible flat cable 5, and the flexible flat cable 5 will pass through the PCB board 406, the sealing rubber plug 2, and the fixed bracket 1 before connecting to the downstream end. Therefore, it is necessary to meet the sealing requirements at the point where the flexible flat cable 5 passes to avoid upstream and downstream gas generation. Therefore, a wire threading groove 404 is provided on the PCB board 406, and an outlet 103 corresponding to the wire threading groove 404 is provided on the fixed bracket 1. A sealing rubber plug 2 is provided in the outlet 103 for the flexible flat cable 5. The sealing rubber plug 2 seals the space between the flexible flat cable 5 and the outlet 103. The wire threading groove 404 corresponds to the outlet 103, allowing wire threading in a compact space.

[0037] The entire motor valve is mounted and connected to the device via a fixing bracket 1. Specifically, a first fixing hole 101 is provided on the fixing bracket 1, through which a fastener is passed and secured to the device. After installation, the flexible flat cable 5 needs to be threaded into the device outlet for sealing. Therefore, a second sealing groove 107 is provided on the downstream end of the fixing bracket 1, coaxial with the outlet 103. This groove is used to accommodate a sealing gasket, ensuring a seal when the fixing bracket 1 is securely attached to the device.

[0038] At the same time, the entire air guide is also sealed through the fixed bracket 1. Therefore, a third sealing groove 106 is provided on the fixed bracket 1 on the end face at the downstream end. After a sealing gasket is placed in the third sealing groove 106, sealing is achieved in a locked state, and upstream and downstream partition sealing is achieved through the third sealing groove 106.

[0039] The second sealing groove 107 and the third sealing groove 106 are isolated from each other and will not cause detection interference.

[0040] In order to facilitate the acquisition of signals for controlling the switching action of the valve body or the switch position status through the PCB board 406, a conductive connection point is required. Therefore, a connecting pad 402 is integrated on the PCB board 406 for soldering the wires, thereby facilitating signal transmission through the connecting socket 403 and the flexible cable 5; of course, the connecting pad can also be replaced by a connector.

[0041] Thus, the PCB 406 is integrated with the connection pads 402, the first sensor 401, the second sensor 407, and the connection socket 403, and is installed and used as an independent PCBA 4. Furthermore, a third fixing hole 405 is formed on the PCB 406. A fastener is passed through the third fixing hole 405 and locked onto the fixing bracket 1, thereby achieving stable and reliable fixation of the entire PCBA 4. By fastening the PCB 406 with the fastener, the sealing ring 3 and the sealing rubber plug 2 are compressed and sealed. Therefore, it is necessary to ensure that the fastener is kept tightened at this point.

[0042] Specifically, the valve body includes a valve body middle frame 8 mounted on the fixed bracket 1. The fixed bracket 1 is provided with a second fixing hole 102. The valve body middle frame 8 is fixed to the fixed bracket 1 by fasteners, and a valve body upper cover 10 is snap-connected to the valve body middle frame 8. A motor 9 and a mechanical transmission mechanism 7 connected to the motor 9 are installed in the valve body middle frame 8. Specifically, the motor 9 is fixed to the valve body middle frame and is covered by the valve body upper cover 10. The mechanical transmission mechanism is located between the valve body middle frame 8 and the fixed bracket 1. The mechanical transmission mechanism 7 is provided with a valve port seal 6 for closing or opening the flow port 105. The control line of the motor 9 is welded to the connecting pad 402, thereby forming an integral structural assembly. Among them, other existing technologies can also be used for the devices constituting the valve body. Among them, the mechanical transmission mechanism 7 can use a gear set to realize the valve port seal 6 to control the opening and closing of the flow port 105.

[0043] Specifically, the motor 9 can be a DC motor 9 or a stepper motor 9. The control line of the motor 9 can be used for forward and reverse installation control, or to detect the rotation angle of the motor 9. The specific control of the motor 9 can be selected according to actual needs, and the control line of the motor 9 is finally fixed to the connecting pad 402, so that the signal is summarized, transmitted and processed on the PCB board 406.

[0044] The above embodiments mainly propose detection of upstream and downstream gas parameters so as to enable the motor valve to have more types of control methods and usage methods. The existing technology can also be considered for the mechanical structure part.
