Problems solved by technology
[0005] First of all, the current structure of the auxiliary oil seal device is only suitable for multi-channel cavities, and cannot realize single-channel cavity oil seals.
[0006] Secondly, the structure of the oil seal auxiliary device is scattered and the integration level is not high
[0007] Thirdly, with the current structure of the fuel hydraulic device, it must be assembled with the fuel distribution device before the oil can be sealed, which complicates the product design structure

The invention discloses a multi-channel gas and liquid feeding device for single channel cavities and belongs to the technical field of liquid fuel injection of liquid fuel ramjets. A mandrel is sleeved with a sleeve, a handle is fixed to the upper end of the mandrel through a nut, the mandrel is capable of moving along the sleeve axially through the rotary handle, the outer screw thread of the lower end of a sleeve flange is fixedly connected to an installation support, the sleeve is fixed to the outer end surface of a fuel hydraulic device corresponding to a sealing screw through the installation support, a sealing gasket is installed between the sleeve and the fuel hydraulic device, and a sealing cavity is arranged in the position lower than a sealing ring of the mandrel of the sleeve; a four-way component is fixed to the sleeve through one end of a communication tube and is communicated with the inner sealing cavity, and a pressure sensor and a vacuum pump are connected to two outer screwed rotary joints of the four-way component on one straight line. The problems of sealing and gas and liquid feeding of the single channel cavities are solved, the sealing structure of the fuel hydraulic device is simplified, and the device can be simplified and miniaturized.
Description
technical field [0001] The invention belongs to the technical field of fuel filling for liquid ramjet engines, and in particular relates to a multi-channel gas-liquid filling device suitable for a single-channel cavity. Background technique [0002] After the fuel hydraulic device is assembled, its inner cavity needs to be oil-sealed. Limited by the structure of the existing fuel hydraulic device, it must be assembled with the fuel distribution device, and then use the sealing and movable characteristics of the multi-channel inner cavity of the fuel distribution device and the valve column, and then complete the oil seal with the aid of the oil seal auxiliary device. refer to figure 1 , figure 2 As shown, the oil seal auxiliary device is mainly composed of three parts: the gas-liquid filling part, the pressing part, and the valve column rod. Two O-rings are used for sealing between the gas-liquid filling part and the fuel distribution device. The gas-liquid filling part ...
