Abstract
The invention discloses a cryogenic fluid filter used for liquid rocket power system tests. The cryogenic fluid filter comprises an internal filter cartridge, an external filter cartridge, protecting sieves and a filter sieve. The filter is made of 06Crl9Ni10 austenitic stainless steel. Sieve pores are formed in the internal filter cartridge and the external filter cartridge and are same in size, and the sieve pores are aligned for mounting. Two layers of protecting sieves and one layer of filter sieve are held between the two filter cartridges, and the bottoms of the internal filter cartridge and the external filter cartridge adopt a welding connection structure. An outer ring at the bottom end of the external filter cartridge is provided with a sealing structure matched with front and rear flange sealing surfaces, and during use, the filter is connected with front and rear pipeline flanges by bolts. The filter with a compact structure and the small appearance is convenient to mount and dismount, saves the mounting space, is suitable for liquid oxygen and other cryogenic working media, and is suitable for a working condition that a medium flows forwards or backwards.
Description
Technical field
The present invention relates to a kind of liquid rocket dynamical system and test cryogen filter used, be applied particularly to cryogenic propellant filling and release on pipeline.
Background technology
Cryogenic liquid Rocket propulsion system testing stand, extremely strict to the control overflow of cryogenic propellant fifth wheel.Fifth wheel enters testpieces can cause seal failure, a series of catastrophic consequence such as rotating device wearing and tearing, clamping stagnation of turbine pump.In addition, the residual propellant after test in rocket body tank, let out and get back to testing stand basin, equally, the cryogenic propellant let out back can not pollute ground system test.Therefore, the filter that can meet forward and reverse flowing is that requisite equipment in system is released in cryogenic propellant filling.
Summary of the invention
Technology of the present invention is dealt with problems: the invention provides a kind of easy accessibility, compact structure, be suitable for the forward and reverse flowing of medium for Rocket propulsion system test cryogen filter.
Technical solution of the present invention: system filter used is released in a kind of liquid rocket dynamical system testing stand cryogenic propellant filling, be made up of outer filter cylinder, interior filter cylinder, protecting wire net and filter screen, above-mentioned parts are by being welded together, outer filter cylinder there is hermetically-sealed construction, is directly clamped in during use on the flange of propellant energy properties pipeline.
The present invention's beneficial effect is compared with prior art:
(1) existing filter majority adopts individual layer filter cylinder, only possesses unidirectional filtering function.The present invention is made up of outer filter cylinder, interior filter cylinder, protecting wire net and filter screen.When upstream fluid flows into, enter filter by the sieve aperture on outer filter cylinder, after the filtration of filter screen and protecting wire net, through the sieve aperture outflow filter of interior filter cylinder, ensure that the clean of downstream propellant.In like manner, downstream fluid, through filter upstream reverse flow, also can isolate the fifth wheel in downstream fluid.So just meet dynamical system test repropellenting and release process, the filtering requirement of the forward and reverse flowing of medium.
(2) existing filter adopts cylindrical filtration cartridges mostly, and this filter adopts tapered filter cylinder, when channel size and filter cylinder length consistent, when fluid flows through tapered filter cylinder, flow resistance is less.
(3) compact structure of the present invention, compared with other products of equivalent specifications, overall dimensions can reduce more than 50%.And, adopt plug-in installation, dramatically saves on installing space.
(4) after the present invention's outer filter cylinder, interior filter cylinder, protecting wire net and filter screen composition overall structure, be Flange joint with the type of attachment of front and back pipeline, use rear dismounting connecting bolt, just filter can be taken out, carry out checking, clean or the work such as replacing, possess the advantage of easy accessibility.
(5) the outer filter cylinder of the present invention, interior filter cylinder all adopt austenitic stainless steel, trade mark 06Cr19Ni10, are applicable to the cryogenic fluid such as liquid oxygen, liquid nitrogen, have widened the equipment warm area scope of application.

Detailed description of the invention
Illustrate that the invention will be further described with specific embodiment below in conjunction with accompanying drawing:
As shown in the figure, filter is directly clamped on the flange of conveyance conduit in use, is ensured the sealing of pipeline by the hermetically-sealed construction supporting with existing flange.The present invention is made up of outer filter cylinder 1, interior filter cylinder 2, protecting wire net 3, filter screen 4, sieve aperture 5, hermetically-sealed construction 6.Interior filter cylinder 2 inserts in outer filter cylinder 1, two filter cylinders have the sieve aperture 5 also one_to_one corresponding of same size, between two filter cylinders, two-layer protecting wire net 3 and one deck filter screen 4 are set, filter screen 4 is clipped between two-layer protecting wire net 3, two filter cylinders and three-layer network at filter cylinder bottom welding together, are clamped in by the hermetically-sealed construction 6 on outer filter cylinder and need on filter pipe.
Operation principle of the present invention is: after filter installs, and the propellant with impurity is out-of-date from upstream flow, can by the sieve aperture inflow filter on outer filter cylinder, after the filtration of filter screen and protecting wire net, and the sieve aperture in flowing on filter cylinder, and then outflow filter.During reverse flow, work principle of filter is identical.Filter cylinder can play the effect of protection filter screen, and the structural design of taper can reduce flow resistance to greatest extent.Protecting wire net can filter the impurity of large-size, and plays the effect of protection filter screen equally.The design of pressing from both sides one deck filter screen in this invention in two filter cylinders, two-layer protecting wire net can ensure that medium is when reverse flow, and filter screen is still safe.
The non-detailed description of the present invention is known to the skilled person technology.
