The inlet gate valve comprises a sealing ring (1), an inlet rear cover (2), a flashboard (3), a shaft (4), an inlet front cover (5) and a pressure rubber (6), can be used for various self-sealing type fuel pumps, and can achieve the effect of maximally reducing the flow resistance of a pipeline in the pump while realizing the self-sealing function of a pump shell after a pump core is disassembled, thereby providing a larger optimization space for the hydraulic performance design of the pump, and in addition, the axial overall dimension of the pump can be greatly reduced through the flat structural design.
Description
Technical Field
The invention belongs to the aviation application technology and relates to an inlet gate valve for a self-sealing pump.
Background
At present, the fuel pump with a self-sealing structure is mainly designed by adopting a plunger type or flap type check valve to realize the sealing function, the check valve overcomes the spring force of the check valve through fuel oil to open the valve, and a designer must make certain consideration when carrying out hydraulic design to reserve certain allowance for hydraulic loss, so that the final performance requirement of a product is ensured.
Disclosure of Invention
The purpose of the invention is as follows: the inlet gate valve for the self-sealing pump is provided, and the hydraulic loss of an inlet pipeline of the pump is reduced to the greatest extent.
The technical solution of the invention is as follows: a self-sealing pump inlet gate valve comprises a sealing ring 1, an inlet rear cover 2, a gate plate 3, a shaft 4 and an inlet front cover 5;
the inlet front cover 5 is tightly connected with the inlet rear cover 2 through bolts, and the inlet front cover 5 is tightly attached to the sealing ring 1 arranged in the sealing groove of the inlet rear cover 2; the shutter 3 is installed inside the gate valve by a shaft 4 inserted into shaft holes of the inlet front cover 5 and the inlet rear cover 2.
The inlet front cover 5 is internally provided with a glue pressing 6 surrounding the inlet pipe.
The flashboard 3 is driven by the pump core ejector rod to rotate around the shaft 4 to control the opening and closing of the inlet pipeline.
The gate plate 3 is tightly pressed with the pressure rubber 6 to realize the sealing of the pump cavity and the pipeline.
The invention has the beneficial effects that: the inlet gate valve for the pump is suitable for various self-sealing fuel pumps, can realize the sealing function of the pump shell, simultaneously furthest eliminates hydraulic loss caused by inlet check valves in other forms, and provides a larger optimization space for the hydraulic performance design of the fuel pumps. In addition, through the structural design of flattening, the axial overall dimension of pump can be reduced by a wide margin, saves bigger space for the installation environment.

Detailed Description
The invention is further described in detail below with reference to the following figures:
as shown in fig. 1, 2 and 3, the pump inlet gate valve with a self-sealing function of the present invention includes a sealing ring 1, an inlet back cover 2, a gate plate 3, a shaft 4, an inlet front cover 5 and a molding compound 6. The inlet front cover 5 is tightly connected with the inlet rear cover 2 through bolts and tightly attached to the sealing ring 1 arranged in the sealing groove of the inlet rear cover 2. The shutter 3 is installed inside the gate valve by a shaft 4 inserted into shaft holes of the inlet front cover 5 and the inlet rear cover 2. The inlet front cover 5 is internally provided with a glue pressing 6 surrounding the inlet pipe.
The sealing ring 1 and the pressure rubber 6 are sealing parts, and sealing between the gate valve and an external space is realized.
The inlet rear cover 2 and the inlet front cover 5 are shell parts of the gate valve and are also support structures of the internal rotating parts.
The gate plate 3 is a rotating part of the gate valve, and the inlet pipeline is opened and closed through rotation.
The shaft 4 is the rotation center of the shutter 3.
The gate valve device is positioned at the inlet of the pump shell, and the gate valve is in a completely closed state when the pump core is not installed in the pump shell; the top end of the pump core is provided with the ejector rod, the ejector rod is inserted into the rotary groove of the inlet rear cover 2 and the slide way hole of the flashboard 3 when the pump core is installed, the pump core is rotated, the flashboard 3 is driven to rotate by a certain angle through the ejector rod until the inlet pipe is completely opened, and fuel enters the pump cavity through the completely opened gate valve after the pump core is electrified to work; when the pump core is disassembled, the pump core is rotated reversely, and the ejector rod drives the flashboard 3 to rotate to a completely closed state. The sealing of the gate valve is realized by the tight joint of the sealing ring 1 between the front cover and the rear cover, the flashboard 3 and the pressure rubber 6.
