Abstract
本实用新型涉及管道连接设备的技术领域，尤其是一种钢制法兰，包括法兰体，法兰体上设置有与外接管道相连接的管状接口，管状接口呈锥型状，与法兰体连接端的管状接口的口径小于管状接口另一端口径。本实用新型的钢制法兰，采用锥型状的管状接口，在将管道与钢制法兰对接时，能够准确对接，从而提高密封性能，不易造成管道的泄漏。
The utility model relates to the technical field of pipeline connection equipment, in particular to a steel flange, which includes a flange body. The flange body is provided with a tubular interface connected with an external pipeline. The caliber of the tubular interface at the body connection end is smaller than the caliber of the other port of the tubular interface. The steel flange of the utility model adopts a tapered tubular interface, which can accurately butt the pipe and the steel flange, thereby improving the sealing performance and not easily causing leakage of the pipe.
Description
技术领域technical field
本实用新型涉及管道连接设备的技术领域，尤其是一种钢制法兰。The utility model relates to the technical field of pipeline connection equipment, in particular to a steel flange.
背景技术Background technique
法兰是使管子与管子相互连接的零件，连接于管端，适用于石油、化工、石油化工、水电、轻纺、核能及制药等各种装置的管道连接。现在大多数管子与阀门之间、管子与管子之间的连接都是将管子与法兰体直接焊接，其结构是将管子与法兰直接进行电焊或哑火焊连接，从而达到密封的目的，这样的连接，其对焊时对焊口不易对准，其操作复杂，并且密封性能差，容易泄漏，焊接处能承受的压力小。Flanges are parts that connect pipes to pipes, and are connected to pipe ends. They are suitable for pipe connections in various devices such as petroleum, chemical, petrochemical, hydropower, textile, nuclear energy, and pharmaceuticals. Most of the connections between pipes and valves, and between pipes are directly welded to the flange body. The structure is to directly connect the pipe and the flange by electric welding or dumb fire welding, so as to achieve the purpose of sealing. The connection is not easy to align the butt welding port during butt welding, the operation is complicated, and the sealing performance is poor, it is easy to leak, and the pressure that the weld can withstand is small.
实用新型内容Utility model content
本实用新型要解决的技术问题是：为了克服上述中存在的问题，提供一种密封性能好、结构简单的钢制法兰。The technical problem to be solved by the utility model is to provide a steel flange with good sealing performance and simple structure in order to overcome the above-mentioned problems.
本实用新型解决其技术问题所采用的技术方案是：一种钢制法兰，钢制法兰，包括法兰体，所述的法兰体上设置有与外接管道相连接的管状接口，所述的管状接口呈锥型状，与法兰体连接端的管状接口的口径小于管状接口另一端口径。The technical scheme adopted by the utility model to solve the technical problem is: a steel flange, a steel flange, including a flange body, the flange body is provided with a tubular interface connected with an external pipeline, so The above-mentioned tubular interface is tapered, and the diameter of the tubular interface connected to the flange body is smaller than the diameter of the other port of the tubular interface.
为了能够使法兰体和外接管道更加紧固固定，所述的法兰体上围绕圆心均匀分布有至少八个对称的通孔。In order to make the flange body and the external pipe more tightly fixed, at least eight symmetrical through holes are evenly distributed around the center of the circle on the flange body.
本实用新型的有益效果是，本实用新型的钢制法兰，采用锥型状的管状接口，在将管道与钢制法兰对接时，能够准确对接，从而提高密封性能，不易造成管道的泄漏。The beneficial effect of the utility model is that the steel flange of the utility model adopts a tapered tubular interface, and when the pipeline is docked with the steel flange, it can be accurately docked, thereby improving the sealing performance and not easily causing leakage of the pipeline .
