Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of combined valve interface assembly, concretely relates to a embedded hydrogen filter interface assembly. BACKGROUND

[0002] In chemical processes, hydrogen is an important raw material or reactant involved in chemical reactions. For example, in ammonia synthesis production, hydrogen and nitrogen react to form ammonia under high temperature and pressure and the action of a catalyst. Combined valves can control the flow and pressure of hydrogen to ensure that the reaction proceeds under suitable conditions and guarantees the safety and efficiency of production. The combined valve is provided with an interface, and an interface assembly for gas inflow is installed at the interface. The gas usually enters the combined valve through the interface assembly from an external gas source such as a gas storage tank or a gas conveying pipeline.

[0003] A filter is usually provided in the interface assembly. When the combined valve is in an open state, the channel of the interface assembly is unobstructed, and the gas enters the combined valve through the interface assembly. In this process, the gas first passes through the filter to remove impurities, and then the clean gas continues to flow to other components inside the valve, such as the valve core and valve cavity. Depending on the specific structure and function of the valve, the gas may be distributed to different channels or outlets.

[0004] However, conventional filters are usually plate-shaped structures that only filter the gas as it passes through. The filtering effect is generally poor, which can easily lead to contamination of valve components by impurities, reducing the service life and increasing the failure rate. SUMMARY

[0005] The utility model provides a embedded hydrogen filter interface assembly to solve the technical problem of poor gas filtering effect of the interface assembly of the combined valve in the prior art, which leads to easy contamination of components by impurities.

[0008] A plurality of filter ports with filter screens are provided through the side wall of the cylinder body, so that the hydrogen entering the gas inlet passes through the plurality of filter ports to enter the interior of the cylinder body, achieving filtration.

[0010] Through the above arrangement, the gas filtering area is increased, the speed of the gas during filtering is slowed down, the filtering effect is greatly improved, and the technical problems that the interface assembly of the combination valve in the prior art has poor gas filtering effect and causes the parts to be easily polluted by impurities are effectively solved.

[0011] Further, the outer sleeve body has a placing hole for inserting the cylinder, the lower end face of the placing hole has a step, and the lower end of the cylinder has an annular bottom plate clamped on the step.

[0012] Further, the outer sleeve body has an air inlet hole in the upper side of the placing hole, the hole diameter of the air inlet hole is smaller than that of the placing hole, and the upper end of the cylinder is arranged in a spaced manner with the lower end of the air inlet hole, so that the gas can flow into the gap channel.

[0013] Further, the lower end of the air inlet hole and the upper end of the placing hole are communicated through a tapered channel flared downward, and the upper end of the cylinder is a tapered structure, so as to improve the smoothness of the hydrogen flow in the air inlet hole.

[0014] Further, the interface structure is an external thread, and the combination valve has a corresponding threaded hole, so that the outer sleeve body is embeddedly installed on the combination valve in a threaded connection manner. The embedded installation can improve the aesthetics of the entire assembly during installation.

[0015] Further, the side wall of the outer sleeve body has a sealing assembly in the lower side of the external thread and a waterproof and dustproof structure in the upper side of the external thread. The sealing assembly and the waterproof and dustproof structure can further protect the entire interface assembly, avoid the pollution of the valve parts by impurities, and improve the service life.

[0016] Further, the outer sleeve body has an embedded groove on the side wall, and the sealing assembly comprises a check ring and an O-ring in the embedded groove.

[0017] Further, the waterproof and dustproof structure is located in the upper side of the external thread and adjacent to the external thread, the side wall of the outer sleeve body has a stop edge in the upper side of the waterproof and dustproof structure, and the stop edge is used for cooperating with the end face of the threaded hole of the combination valve to press the waterproof and dustproof structure.
