Description
Technical field
A kind of valve of the present invention is related to a kind of modularization low pressure and cuts through formula gas explosion valve.
Background technology
Gas explosion valve is the key component of the pre-packaged module of propellant before power system operational, is sealed up for safekeeping reliably and with long-term directly certainly
The tank service life of dynamical system is determined.This requires can guarantee under the most evil bad environmental condition of gas explosion valve reliably and with long-term storage and can
By action, also require apparent size small, it is light-weight.Currently, the accumulating structure used in dynamical system tank is to cut through film both at home and abroad
Chip generally installs the diaphragm with indentation in reservoir outlet, cannot be satisfied long shelf appeal and high reliability.In the past in power
Rupture disc of the pre-packaged use of propellant with indentation before system work, the diaphragm production difficulty is big and of high cost, is broken after long storage
Split rupture of diaphragm pressure transient.If being pushed into agent seriously corroded at rupture disc indentation, propellant can be caused to reveal, to lead
Entire dynamical system is caused to fail.
The major parameter of gas explosion valve has：Cut through pressure and leakproofness.It is more more consistent better to cut through pressure, it is meant that gas explosion valve is cut
Broken power can accurately control, and ensure enough operation margins；Leakproofness is better, it is meant that action is front and back without leakage.
Invention content
In order to solve the above technical problems, the present invention provides a kind of modularization low pressure to rupture formula gas explosion valve, and ensure long-term
It is reliable seal up for safekeeping and when system works propellant regular supply.
The invention is realized by the following technical scheme：
A kind of modularization low pressure cuts through formula gas explosion valve, includes carrying O-ring V by what attachment screw linked together
Tank 7, strainer and shell；The guide sleeve with O-ring III is equipped in the shell, be equipped in the guide sleeve with baffle ring and
The piston of O-ring II and cutter with two pass O-ring I；Diaphragm with O-ring IV, the cutter are installed in the tank
It is fixed on above the diaphragm by position-limiting ear, the diaphragm is using no indentation and diaphragm in homogeneous thickness.
Preferably, further include the air cavity A for being set to upper end side in shell, the downstream pipe C of interior lower end both sides and set
It is placed in the sap cavity B of tank lower end.
Preferably, the strainer is vertically installed in the downstream pipe between guide sleeve and tank.
Preferably, which cuts through mode using low pressure.
Preferably, the piston and cutter are split type setting.
Preferably, the cutter is equipped with position-limiting ear, prevents from malfunctioning.
A kind of modularization low pressure of the present invention ruptures formula gas explosion valve using no indentation and diaphragm in homogeneous thickness, solves power
What propellant was pre-packaged before system work seals problem up for safekeeping reliably and with long-term, since its driving force replaces electric detonator using 2MPa gases,
Tank module is reusable simultaneously, need to only replace gas explosion valve, substantially reduces product cost, and save electricity money for system
Source.It uses cutter split type with piston again, ensures that big piston offer cuts through nargin enough and valve piston ensures to be oriented to, to significantly
Lower product weight, improves cutter Reliability of Microprocessor.Therefore, the present invention achieves modularization, low pressure is cut through, the long-life and tie
Simple, the light-weight advantageous effect of structure.
Description of the drawings
Fig. 1 is a kind of sectional view of modularization low pressure rupture formula gas explosion valve of the present invention.
In figure label for：1-shell, 2-pistons, 3- cutters, 4-guide sleeves, 5-strainers, 6-diaphragms, 7-tanks,
8-screws, 9-baffle rings, 10-O-rings I, 11-O-rings II, 12-O-rings III, 13-O-rings V, 14-O-rings IV.
Specific implementation mode
Illustrate the preferred embodiment of the present invention below in conjunction with the accompanying drawings.
As shown in Figure 1, an embodiment of the present invention provides a kind of modularization low pressure to cut through formula gas explosion valve, including by connecting spiral shell
The tank 7 with O-ring V 13, strainer 5 and the shell 1 that nail 8 links together；It is equipped in the shell 1 and carries O-ring III 12
Guide sleeve 4, the piston 2 with baffle ring 9 and O-ring II 11 and the cutter with two pass O-ring I 10 are equipped in the guide sleeve 4
3；Diaphragm 6 with O-ring IV 14 is installed, the cutter 3 is fixed on by position-limiting ear on the diaphragm 6 in the tank 7
Side, the diaphragm 6 is using no indentation and diaphragm in homogeneous thickness；Further include the air cavity A for being set to upper end side in shell 1, interior
The downstream pipe C of the lower end both sides and sap cavity B for being set to 7 lower end of tank, the strainer 5 are vertically installed at guide sleeve 4 and storage
In downstream pipe C between case 7.
This specific implementation is in use, when the low-pressure gas from pressure reducing valve downstream enters gas explosion valve air cavity A, low-pressure gas
It acts on piston, pushes piston motion, piston that cutter action, position-limiting ear is pushed to be pulled off, cutter action cuts through diaphragm, stores
Case liquid enters downstream pipe C from sap cavity B, is used for system.Air cavity A active forces are more than sap cavity B active forces, and cutter is fixed on
Cut through position.
From the above mentioned, the present invention utilizes no indentation and diaphragm in homogeneous thickness, solution due to the technical solution more than taking
What propellant was pre-packaged before power system operational seals problem up for safekeeping reliably and with long-term.Since its driving force replaces electricity using 2MPa gases
Booster, while tank module is reusable, need to only replace gas explosion valve, substantially reduces product cost, and be system section
About electric resources.It uses cutter split type with piston again, ensures that big piston offer cuts through nargin enough and valve piston ensures to be oriented to, from
And lower product weight significantly, improve cutter Reliability of Microprocessor.Therefore, the present invention achieves modularization, low pressure is cut through, long-lived
Life and simple in structure, light-weight advantageous effect.
Specific embodiments of the present invention are described above.It is to be appreciated that the invention is not limited in above-mentioned
Particular implementation, those skilled in the art can make various deformations or amendments within the scope of the claims, this not shadow
Ring the substantive content of the present invention.
