Abstract
The invention discloses the volume control device of a kind of gases at high pressure, be made up of the conical surface and orifice plate profile two parts, use red copper as material, it is possible to meet the demand of high-pressure gas seal and flow-control simultaneously.This apparatus structure is small and exquisite, easy accessibility, saving installing space, it is adaptable to what high-pressure gas flow controlled supplies distribution pipeline.
Description
Technical field
The present invention is that the high-pressure gas flow used by the test of a kind of liquid rocket dynamical system controls device, it is possible to simultaneously full
Foot high-pressure gas seal and the demand of flow-control, it is adaptable to what high-pressure gas flow controlled supplies distribution pipeline.
Background technology
The test of liquid rocket dynamical system, to requiring higher for gas medium, supply gas pressure, gas supply flow, is nitrogen for gas medium
Gas, hydrogen, helium, the highest supply gas pressure 35MPa, gas supply flow scope is at 15g/s～380g/s.Usual at tradition air feed craft
Constrictor can be selected as the flow control element of gas, have two kinds with the mode of pipeline assembly connection: Flange joint and screw thread
Compress and connect.And in actual mechanical process, both modes but also exist weak point:
(1) testing in liquid rocket dynamical system, owing to gas supply flow scope is relatively wider, constrictor to be carried out the most more
Change, as used flange connection, operation complexity is installed, wastes time and energy；
(2) using screw thread to compress connected mode, sealing is poor, especially at the helium supply line of operating pressure 35MPa.
Meanwhile, supply air line will be through technological processes such as welding, pickling, passivation before installing, and the globe joint of pipeline easily weares and teares, and it is close
Envelope property is worse.
Accordingly, it would be desirable to a kind of be not only easily installed, sealing property but also good volume control device.
Summary of the invention
The technology of the present invention solves problem: the invention provides a kind of easy accessibility, compact structure, can meet high pressure gas
Body sealing, can play again the device of flow-control, and can be used for Rocket propulsion system test supplies distribution pipeline.
The technical solution of the present invention: 37 ° of high pressure bulbs of tradition seal by welding straight coupling 1, cap nut 3 and ball
Shape joint 4 forms.The present invention arranges special conical gasket 2 between welding straight coupling 1 and globe joint 4.Sealing gasket 2
It is made up of the conical surface and orifice plate profile two parts.Welding straight coupling 1 welds with supply air line, and globe joint 4 welds with another pipeline
Connect, conical gasket 2 is arranged on globe joint, and with cap nut by straight-through for the welding conical surface pressure with conical gasket
Tightly, conical gasket installation on high-pressure air feed pipeline is completed.
The conical surface seals, conical surface thickness 1mm, and cone angle is 37 °, can meet pressure spherical less than or equal to 35MPa gas
The demand sealed.Orifice plate profile plays gas flow control action, and profile thickness should be less than or be equal to 0.05 times of caliber, hole-shaped
Formula can select right angle aperture, wedge angle aperture and nozzle orifice according to demand, and aperture can be determined according to gas flow.
The present invention compared with prior art provides the benefit that:
(1) improving the sealing problem that pressure duct is threaded, especially working pressure range is at 23MPa～35MPa,
The helium supply line of caliber DN15～DN32.
(2) its simple in construction, it is simple to install, for the pipeline that gas supply flow scope is wider, it is possible to achieve be switched fast
Function.
Accompanying drawing explanation
Fig. 1 is that conical gasket installs sectional structure chart.1 it is welding straight coupling, 2 is conical gasket, 3 is overcoat spiral shell
Female, 4 be globe joint.
Detailed description of the invention
The invention will be further described with specific embodiment in explanation below in conjunction with the accompanying drawings:
As it is shown in figure 1, this erecting device is by welding straight coupling 1, conical gasket 2, cap nut 3 and globe joint 4
Composition.Wherein welding straight coupling welds with supply air line, and globe joint welds with another pipeline, is arranged on by conical gasket
On globe joint, and the conical surface with conical gasket welding is straight-through with cap nut compresses, and completes conical gasket at high pressure
Installation on supply air line.
The operation principle of the present invention is: when gases at high pressure are carried out in the face of gases at high pressure through conical gasket, orifice plate type
Current limliting, serves the effect of flow-control, and the conical surface presses in globe joint, it is achieved that the sealing function of gases at high pressure.
The present invention is successfully applied to liquid rocket dynamical system test 35MPa helium tank loading line, flow 15g/s；
12MPa cabin section blows down pipeline, flow 380g/s；And achieve good application effect.
Claims (4)
1. a kind of taper orifice plate sealing gasket of invention, it is characterised in that: this pad is made up of the conical surface and orifice plate profile two parts, permissible
Meet simultaneously and seal and the effect of flow-control.There is a through hole at pad center, and aperture is less than caliber, can be true according to gas flow
Gases at high pressure are played the effect of current limliting by the size of set aperture.
Pore plate by sealing pad the most according to claim 1, it is characterised in that: employing red copper is as material, and makes annealing treatment.
Pore plate by sealing pad the most according to claim 1, it is characterised in that: the conical surface and orifice plate profile use different-thickness, and the conical surface is thick
