Description

Technical Field

[0001] The invention relates to the field of hydrogen equipment technology, specifically to an ionic liquid hydrogen compression device used in hydrogen pressurization, storage, transportation, and hydrogen refueling station equipment. Background Technology

[0002] Hydrogen energy, as a representative of clean energy, has broad application prospects. Hydrogen gas at atmospheric pressure cannot be efficiently stored and transported; pressurization is a necessary condition for its application. Ionic liquid hydrogen compressors are highly reliable and have been proven and widely used in applications such as hydrogen pipeline transportation and hydrogen refueling stations. With the rapid development of the industry, the market needs ionic liquid compressors with larger displacements. However, existing ionic liquid compressors only have one set of intake and exhaust valves per cylinder, resulting in slow response when facing large-displacement applications. The application of multi-valve structures can effectively improve this situation. Currently, there are few patents and solutions related to multi-valve cylinder head structures for ionic liquid hydrogen compressors. Summary of the Invention

[0003] The purpose of this invention is to address the problem of slow response of a single valve in existing ionic liquid compressors by disclosing a multi-valve cylinder head structure for an ionic liquid hydrogen compressor, comprising: a valve assembly, an exhaust valve bracket, an intake valve bracket, a four-valve cylinder head, a three-valve cylinder head, a cylinder head cover plate, cylinder head cover plate bolts, an intake connector, and an exhaust connector; the four-valve cylinder head can accommodate four valve assemblies, and the three-valve cylinder head can accommodate three valve assemblies.

[0004] In the improved scheme, the multi-valve cylinder head structure is characterized in that: the four-valve cylinder head has two intake passages, two exhaust passages, one intake port, and one exhaust port inside; the intake port is connected to the two intake passages, and the exhaust port is connected to the two exhaust passages; the three-valve cylinder head has two intake passages, one exhaust passage, one intake port, and one exhaust port inside; the intake port is connected to the two intake passages, and the exhaust port is connected to the one exhaust passage.

[0005] The advantages and positive effects of this invention are as follows:

[0006] The intake and exhaust response is fast because the increased number of valves increases the amount of gas flowing through per unit time. Therefore, better intake and exhaust response can be obtained in large-displacement applications, thereby reducing energy loss; at the same time, it is also more beneficial for the circulation of ionic liquids.

[0007] It has high space utilization. Because multiple valves are compactly integrated inside a cylinder head, the volume occupied is not increased compared to a cylinder head with a single valve structure; and it does not affect the assembly with other existing components; depending on the different pressure and flow requirements, a three-valve cylinder head or a four-valve cylinder head can be selected.

[0008] With low maintenance costs, the valve assembly is embedded in the cylinder head and fixed by the exhaust valve bracket or intake valve bracket and cylinder head cover plate, making it easy to disassemble and replace, which can improve maintenance efficiency and thus reduce maintenance time.
