DETAILED DESCRIPTION

[0025] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0027] Some embodiments of an electric liquid hydrogen regulating valve according to the present invention are described below with reference to FIG. 1 and FIG. 2 .

[0028] As shown in FIG1 and FIG2 , an embodiment of the present invention provides an electric liquid hydrogen regulating valve, including a housing, a control assembly, and a throttling assembly.

[0029] Specifically, the shell is provided with a accommodating cavity 3 inside, a liquid outlet 14 connected to the accommodating cavity 3 is opened at one end of the shell, and a liquid inlet 13 is opened on the side wall of the shell; the control component is arranged inside the accommodating cavity 3; the throttling component is arranged inside the accommodating cavity 3, the throttling component is located on the side of the control component close to the liquid outlet 14, and the throttling component is connected to the control component.

[0030] By arranging a receiving cavity 3 inside the shell, a control component is fixedly installed inside the receiving cavity 3. The control component can control the throttling component arranged inside the receiving cavity 3. The throttling component can control the opening and closing degree of the liquid outlet 14, thereby controlling the flow rate of the entire liquid hydrogen. By arranging the control component inside the receiving cavity 3, the space outside the cold box occupied by the control component can be reduced, thereby improving the space utilization rate of the device.

[0031] As shown in FIG1 , in one embodiment of the present invention, the housing includes:

[0032] The valve body 1, the accommodating cavity 3 is opened in the valve body 1;

[0033] The valve cover 2 is provided at one end of the valve body 1 away from the liquid outlet 14 , and the accommodating cavity 3 is connected to the valve cover 2 .

[0034] The control component includes:

[0035] A base 4 is provided inside the accommodating cavity 3, and a vacuum insulation chamber 5 is provided inside the base 4;

[0036] A controller 6 is provided at one end of the base 4 close to the valve cover 2, and the controller 6 passes through the valve cover 2;

[0037] The motor 7 is disposed inside the accommodating cavity 3 , and the motor 7 is disposed at an end of the base 4 away from the valve cover 2 .

[0038] The throttling component includes:

[0039] a throttle member 8, one end of which is connected to the output end of the motor 7;

[0040] The throttle plug 9 is connected to the other end of the throttle member 8 , and the size of the throttle plug 9 gradually increases from the throttle member 8 toward the motor 7 .

[0041] When the flow of liquid hydrogen needs to be adjusted, the controller 6 fixedly connected to the end of the base 4 close to the valve cover 2 sends an instruction, and the motor 7 fixedly connected to the end of the base 4 away from the valve cover 2 receives the instruction sent by the controller 6, and then the output end of the motor 7 extends or contracts, thereby driving the throttle member 8 fixedly connected to the output end of the motor 7 to move downward or upward, and then driving the throttle plug 9 fixedly connected to the end of the throttle member 8 away from the motor 7 to move downward or upward. Since the size of the throttle plug 9 gradually increases from the throttle member 8 toward the motor 7, the up and down movement of the throttle plug 9 can adjust the gap between the throttle plug 9 and the liquid outlet 14, thereby adjusting the flow of liquid hydrogen. The principle of adjusting the flow of liquid hydrogen is existing technology and will not be elaborated here.

[0042] By installing a base 4 inside the accommodating cavity 3, a controller 6 is fixedly connected to the end of the base 4 close to the valve cover 2. The controller 6 passes through the valve cover 2 and extends out of the valve body 1, which makes it convenient for the operator to adjust the controller 6 during work. A motor 7 is fixedly connected to the end of the base 4 away from the valve cover 2. By arranging the motor 7 inside the accommodating cavity 3, it is possible to avoid the motor 7 being installed outside the valve body 1 to increase the occupied space, thereby improving space utilization. The motor 7 adopts an ultra-low temperature motor 7, which can meet the low temperature working environment.

[0043] A valve cover 2 is provided at the end of the valve body 1 away from the liquid outlet 14. The valve cover 2 and the valve body 1 are connected by bolts. When the motor 7, throttle member 8 and other components need to be taken out, it is only necessary to remove the bolts connecting the valve cover 2 and the valve body 1, and then the parts inside the cavity 3 can be taken out, which is easy to operate.

[0044] By providing a vacuum insulation chamber 5 inside the base 4 , the heat conduction area between the base 4 and the external atmosphere can be reduced, thereby reducing the external heat from entering the accommodating cavity 3 .

[0045] As shown in Figure 2, in one embodiment of the present invention, a first limiting groove 10 and a second limiting groove 11 are respectively provided on the opposite surfaces of the valve body 1 and the valve cover 2, the first limiting groove 10 and the second limiting groove 11 are arranged opposite to each other, the first limiting groove 10 is connected to the accommodating cavity 3, and a limiting block 12 is provided at one end of the base 4 near the valve cover 2, and the edge of the limiting block 12 is placed between the first annular groove and the second annular groove.

[0046] A first limiting groove 10 connected to the accommodating cavity 3 is provided at the upper end of the valve body 1, and a second limiting groove 11 is provided on the lower surface of the valve cover 2. The first limiting groove 10 and the second limiting groove 11 are the same in shape and size. A limiting block 12 is fixedly connected to the upper end of the base 4. The limiting block 12 is annular in shape, and the edge of the limiting block 12 is placed between the first limiting groove 10 and the second limiting groove 11. The base 4 is fixed by installing the limiting block 12 to prevent the base 4 from being offset.

[0047] As shown in FIG. 1 , in one embodiment of the present invention, a high thermal resistance thermal bridge is provided between the throttling member 8 and the motor 7 .

[0048] By designing a high thermal resistance thermal bridge between the throttle 8 and the motor 7, the heat generated by the motor 7 can be prevented from affecting the liquid nitrogen. The high thermal resistance thermal bridge is constructed of thermal insulation materials in the prior art, and the construction principle is also in the prior art, so it will not be described in detail here.

[0049] The present invention has the following advantages:

[0050] 1. By arranging the control component inside the accommodating cavity 3, the space outside the cold box occupied by the control component can be reduced, thereby improving space utilization.

[0051] 2. By providing a vacuum insulation chamber 5 inside the base 4 , the heat conduction area of ​​the base 4 can be reduced, further reducing the heat from the external atmosphere from entering the accommodating cavity 3 .
