Description

Technical Field

[0001] This utility model relates to the field of methanol burner technology, specifically to an automatic control device for methanol fuel pump flow return valve. Background Technology

[0002] The automatic control methanol fuel pump flow return valve is a controllable flow valve device on the burner equipment. It is mainly used to connect to the controller to transmit data and control the flow. During use, the methanol fuel pump flow return valve is mainly installed on the methanol fuel delivery pipeline to monitor the methanol flow data in real time. However, due to the small diameter of the methanol fuel delivery pipeline, the support strength of the methanol fuel pump flow return valve is insufficient when it is installed on the methanol fuel delivery pipeline through the pipeline connector. During the operation of the burner, the methanol fuel pump flow return valve is prone to shaking due to vibration. Under long-term vibration, the methanol fuel pump flow return valve and the pipeline connector are prone to deformation and damage, which affects the continuity and accuracy of the methanol fuel flow detection.

[0003] Therefore, there is an urgent need for an automatic control device for the flow return valve of methanol fuel pumps to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an automatic control device for the flow return valve of a methanol fuel pump, which can effectively reduce the risk of deformation and damage at the connection between the valve body and the pipeline connector.

[0005] The purpose of this utility model is achieved as follows: an automatic control device for a methanol fuel pump flow return valve, comprising:

[0006] The valve body and the methanol fuel delivery pipeline are connected to the methanol fuel delivery pipeline via a pipeline connector.

[0007] Also includes:

[0008] A support assembly installed in a methanol fuel delivery pipeline to support the valve body;

[0009] The support assembly includes support pipes disposed on both sides of the valve body. The support pipes are installed in the methanol fuel delivery pipeline through a second connecting assembly. The support pipes are connected to a support rod through a compression assembly. The other end of the support rod extends out of the support pipe and is connected to the valve body through a first connecting assembly.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This invention, through the setting of the support component, provides the valve body with increased support strength and vibration buffer protection through the squeezing action of the squeezing component and the damping buffer mechanism formed by the damping fluid passing through the buffer hole. This reduces the risk of deformation and damage at the connection between the valve body and the pipe connector, thereby ensuring the continuity and accuracy of the methanol fuel pump flow return valve in detecting methanol fuel flow.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1

[0019] like Figure 1-4 As shown, an automatic control device for methanol fuel pump flow return valve includes:

[0020] The valve body 101 and the methanol fuel delivery pipeline 102 are connected to the methanol fuel delivery pipeline 102 through the pipeline connector 103.

[0021] Its characteristic is that it further includes:

[0022] A support assembly installed in the methanol fuel delivery pipeline 102 to support the valve body 101;

[0023] The support assembly includes support pipes 201 disposed on both sides of the valve body 101. The support pipes 201 are installed in the methanol fuel delivery pipeline 102 through a second connecting assembly. The support pipes 201 are connected to a support rod 202 through a compression assembly. The other end of the support rod 202 extends out of the support pipes 201 and is connected to the valve body 101 through a first connecting assembly.

[0024] It should be noted that: through the setting of the support components, the damping buffer mechanism formed by the extrusion of the extrusion components and the damping fluid passing through the buffer hole 4 provides increased support strength and vibration buffer protection for the valve body 101, thereby reducing the risk of deformation and damage at the connection between the valve body 101 and the pipe connector 103, and thus ensuring the continuity and accuracy of the methanol fuel pump flow return valve in detecting methanol fuel flow.

[0025] It is worth noting that the methanol fuel pump flow return valve device mainly includes components such as flow sensor, return valve and controller. As it is existing technology, it will not be elaborated on here.

[0026] like Figure 4 As shown: The automatic control methanol fuel pump flow return valve device is characterized in that: the extrusion assembly includes an extrusion plate 301 slidably disposed in a support tube 201, the bottom end of the support rod 202 is connected to the extrusion plate 301, and a spring 302 is provided inside the support tube 201 and between the extrusion plate 301 and the bottom of the support tube 201.

[0027] It should be noted here that: by setting up the extrusion component, while increasing the support strength of the support rod 202 on the valve body 101, its elastic force is used to buffer and protect the valve body 101 from vibration.

[0028] like Figure 4 As shown: The extrusion plate 301 has multiple buffer holes 4, and the support tube 201 is filled with damping fluid, which passes through each buffer hole 4.

[0029] It should be noted here that the buffer hole 4 is used to dampen the flow of the damping fluid, thereby forming a damping buffer mechanism.

[0030] Working Principle: When in use, the methanol fuel pump flow return valve is first connected to the methanol fuel delivery pipeline 102 via pipe connector 103. Then, using the first and second connecting components, and with the cooperation of the limiting component, the support rod 202 and valve body 101 are connected, as well as the support pipe 201 and methanol fuel delivery pipeline 102 are connected. After the valve body 101 is installed, the burner can be turned on. After the methanol fuel pump starts, methanol begins to flow in the methanol fuel delivery pipeline 102. The flow sensor monitors the methanol flow rate in real time and converts the flow signal into an electrical signal, such as an analog voltage or current signal, or a digital pulse signal, which is then transmitted to the controller. After receiving the flow signal, the controller compares it with the internally preset flow target value. If the actual flow rate deviates from the target value, the controller... The controller generates control signals based on a preset control algorithm. For example, using a proportional-integral-derivative (PID) control algorithm, the controller calculates the proportional, integral, and derivative operations of the deviation to obtain a suitable control output, thereby achieving fast, accurate, and stable flow control. The control signals generated by the controller are transmitted to the drive unit of the return valve, such as the drive circuit of a solenoid valve or the motor driver of an electric regulating valve, to drive the return valve. If the actual flow is too large, the opening of the return valve increases, causing some methanol to flow back, thereby reducing the methanol flow delivered to the combustion equipment or other application terminals. If the actual flow is too small, the opening of the return valve decreases or even closes, allowing more methanol to flow to the terminal and increasing the output flow. Throughout the process, the controller continuously adjusts based on the real-time flow data fed back by the flow sensor to keep the methanol flow stable near the target value.

[0031] Meanwhile, during the burner's operation, the extrusion assembly increases the support strength of the valve body 101 by utilizing the support tube 201 and support rod 202. Furthermore, the elastic force of the extrusion assembly and the damping buffer mechanism formed by the damping fluid passing through the buffer hole 4 provide two layers of buffer protection for the valve body 101. This increases the support strength and provides buffer protection against vibration, reducing the risk of deformation and damage at the connection between the valve body 101 and the pipe connector 103. Consequently, it ensures the continuity and accuracy of the methanol fuel pump flow return valve's detection of methanol fuel flow.

The two first bearing seats 602 are connected to a first mounting plate 603 by a limiting assembly. The first mounting plate 603 is connected to the support rod 202.

[0034] It should be noted here that the first connecting component is used to connect the support rod 202 and the valve body 101.

Two flexible locking bands 502 are fixedly connected to one side of the arc-shaped plate 501, and a locking frame 503 is fixedly connected to the other side wall of the arc-shaped plate 501. The two locking frames 503 are threadedly connected to T-shaped clamping rods 504 for clamping the flexible locking bands 502.

The two second bearing seats 505 are connected to a second mounting plate 506 through a limiting assembly. The second mounting plate 506 is connected to the bottom of the support pipe 201.

[0036] It should be noted here that the second connecting component is used to connect the support pipe 201 to the methanol fuel delivery pipe 102.

[0037] like Figure 3 As shown, the limiting component includes studs 701 inserted into two first bearing seats 602 and a second bearing seat 505. The side wall of the studs 701 has a limiting hole 702, and the limiting hole 702 is provided with a pin 703.

[0038] It should be noted here that: by setting the limiting component, the bolt 701 is inserted into the two first bearing seats 602 and the first mounting plate 603 or the second bearing seat 505 and the second mounting plate 506, and the pin 703 is used for limiting, thereby connecting the support rod 202 and the valve body 101 or connecting the support pipe 201 and the methanol fuel delivery pipeline 102.

[0039] It is worth noting that the pin 703 is mainly composed of a screw and a nut threaded to the screw. At the same time, the two first bearing seats 602, the first mounting plate 603, the second bearing seat 505, and the second mounting plate 506 are all provided with insertion holes.
