Specific implementation mode
With reference to specific embodiment, the present invention is described in detail.Following embodiment will be helpful to the technology of this field
Personnel further understand the present invention, but the invention is not limited in any way.It should be pointed out that the ordinary skill of this field
For personnel, without departing from the inventive concept of the premise, various modifications and improvements can be made.These belong to the present invention
Protection domain.
As shown in Figure 1, an embodiment of the present invention provides a kind of novel high-pressure unidirectional self-lock valve, including valve seat 1 and shell 3,
Valve seat 1 and shell 3, which are connected through a screw thread, constitutes inner cavity, and realizes sealing by O-ring 18 and O-ring 10, and interior intracavitary is from import
To outlet be sequentially installed with inlet filter 19, self-locking valve core 2, be attracted pedestal 4, armature 6, mandril 7, check-valve body 11,
Inner elements of check valve 9, spring 14, spring base 13 and outlet filter 12, inner elements of check valve 9, spring 14, spring base 13 are mounted on single
Into valve chest 11, spring 14 is mounted between inner elements of check valve 9 and spring base 13, and one end is fixedly mounted with spring base 13,
Both sides are symmetrically installed with the circle 15 that bursts at the seams, locking magnet ring 5 and close coil 16 3 outside of shell up and down, burst at the seams and enclose 15 and close outside coil 16
Portion is equipped with case 17, and the locking magnet ring 5 is embedded to be mounted on shell 3, and is connected with coil 16 is closed with circle 15 is burst at the seams.
It is also provided with instrument connection on the shell 3, by blocking 8 welded seals after being completed.
The self-locking valve core 2 is connected through a screw thread with armature 6, realizes the linkage of the two.
The mandril 7, by welding, realizes the linkage of the two, in valve-closed state, mandril 7 and check valve with armature 6
Preset clearance δ is equipped between spool 9.
The self-locking valve core 2 is synchronous with 9 on off state of inner elements of check valve.
When unidirectional self-lock valve is opened, inner elements of check valve 9 is not closed with pressure change.
As shown in Fig. 2, a kind of novel high-pressure unidirectional self-lock valve of the embodiment of the present invention can be divided into self-locking valve portion A and check valve
Part B.
The operation principle of this specific implementation is：Valve is closed, and the circle 15 that bursts at the seams is powered, and armature 6 drives latching valve
Spool 2 and mandril 7 move, and mandril 7 overcomes one-way valve spring power so that latching valve and check valve are in open position；Burst at the seams circle
14 power-off, under the permanent magnetism force effect of locking magnet ring 5, armature 6 is maintained at open position, so that latching valve and check valve are equal
It is maintained at open position, and inner elements of check valve 9 does not change with inlet pressure and closed.It is powered conversely, closing coil 16, armature 6
Self-locking valve core 2 and mandril 7 is driven to move to closed position, check valve is closed under the active force of spring 14；It closes
Coil 16 powers off, and armature 6 is maintained in its closed position under the permanent magnetism force effect of locking magnet ring 5, so that latching valve and unidirectional
Valve is held in closed position, and such high pressure unidirectional self-lock valve increases together in addition to the sealing of latching valve when closed by unidirectional
Valve group at sealing function.
Specific implementation is realized the linkage of the two, is had the following advantages using the integrated design of latching valve and check valve：
It gathers around and does not need the steady-working state that power supply offer energy can keep valve opening to obtain closing there are one state holding mechanism；
When valve opening, check valve is not closed with pressure change；When valve is closed in addition to latching valve seals, also add together by unidirectional
Valve group at sealing function.The present invention has latching valve and check valve double sealing, and simple in structure, low in energy consumption, can be widely
It applies among the propulsion system of spacecraft.
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.
