Embodiment Construction

[0020] The invention provides a pressure-resistant injection head to solve the technical problem that the injection head is not resistant to high pressure in the prior art.

[0021] The general idea of ​​the technical solution of the present invention is to provide a new pressure-resistant injection head with high pressure resistance, corrosion resistance, high sealing reliability and long life. The pressure-resistant injection head adopts a flat soft-sealed structure, which is composed of a body 1, a gland nut 2, a plug core 3 and a sealing washer 4. It has a simple structure, tight connection, and strong pressure resistance.

[0022] In order to better understand the technical solution of the present invention, the technical solution of the present invention will be described in detail below through the accompanying drawings and specific examples. It should be understood that the embodiments of the present invention and the specific features in the examples are detailed descr...

Abstract

The invention belongs to the technical field of mechanical engineering, and relates to a pressure-resistant injection head which is used for connecting pipelines. The pressure-resistant injection head comprises a body, a gland nut, a plugging core and a sealing gasket, wherein the body is a circular barrel with an I-shaped section contour and a hollow interior, through holes for connecting the pipelines are formed in the wall, close to the bottom, of the cylinder barrel, the plugging core is installed on the upper portion of the body through the gland nut, the gland nut and the body are connected through external threads located on the gland nut and internal threads located on the body, and the sealing gasket is arranged between the plugging core and the body. According to the pressure-resistant injection head, the technical problem that an injection head is not resistant to high pressure in the prior art is solved, and the technical effect that when the working pressure is larger than 3.0 MPa, the injection head can still keep good strength and sealing can be achieved.

Description

technical field [0001] The invention belongs to the technical field of mechanical engineering, in particular to a high-pressure-resistant injection head. Background technique [0002] The existing marine copper alloy pressure-resistant injection head is a national standard - CB960-1980 "Pressure-resistant Injection Head", which has the following defects: [0003] It is suitable for pressure-resistant injection heads whose working pressure is not greater than 3.0MPa. When the working pressure is greater than 3.0MPa, the strength and sealing effect are poor, which cannot meet the working strength and sealing requirements. Contents of the invention [0004] In order to solve the above-mentioned problems in the prior art, the present invention provides a pressure-resistant injection head to solve the technical problem of low pressure resistance of the injection head in the prior art. [0005] The technical solution adopted in the present invention is to provide a pressure-res...
