Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in detail.Following example will assist in those skilled in the art
Member is further appreciated by the present invention, but limits the present invention the most in any form.It should be pointed out that, the common skill to this area
For art personnel, without departing from the inventive concept of the premise, it is also possible to make some deformation and improvement.These broadly fall into
Protection scope of the present invention.
As it is shown in figure 1, embodiments provide a kind of novel high-pressure unidirectional self-lock valve, including valve seat 1 and housing 3,
Valve seat 1 and housing 3 are threaded connection composition inner chamber, and realize sealing by O 18 and O 10, inner chamber
In be sequentially installed with from import to outlet inlet filter 19, latching valve spool 2, adhesive pedestal 4, armature 6, push rod 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 arranged in check-valve body 11, and spring 14 is arranged on inner elements of check valve 9 and spring base 13
Between, and one end fixedly mounts with spring base 13, the outside lateral symmetry up and down of housing 3 is provided with burst at the seams circle 15, locking
Magnet ring 5 and pass coil 16, the circle 15 that bursts at the seams is outside with pass coil 16 is provided with case 17, and described locking magnet ring 5 is embedded
It is arranged on housing 3, and is all connected with closing coil 16 with the circle 15 that bursts at the seams.
Instrument connection is also had, by blocking 8 welded seals after being completed on described housing 3.
Described latching valve spool 2 is threaded connection with armature 6, it is achieved the linkage of the two.
Described push rod 7 passes through to weld with armature 6, it is achieved the linkage of the two, at valve-closed state, push rod 7 is with unidirectional
Preset clearance δ it is provided with between valve core 9.
Described latching valve spool 2 is Tong Bu with inner elements of check valve 9 on off state.
When unidirectional self-lock valve is opened, inner elements of check valve 9 is not closed with pressure change.
As in figure 2 it is shown, embodiment of the present invention one novel high-pressure unidirectional self-lock valve can be divided into latching valve part A and check valve
Part B.
Originally the operation principle being embodied as is: valve is closed, and circle 15 energising of bursting at the seams, armature 6 drives self-locking
Valve core 2 and push rod 7 move, and push rod 7 overcomes one-way valve spring power so that latching valve and check valve are all in open position；
Bursting at the seams and enclose 14 power-off, under the permanent magnetic effect of locking magnet ring 5, armature 6 is maintained at open position, so that from
Locking-valve and check valve are held in open position, and inner elements of check valve 9 is not closed with inlet pressure change.Otherwise,
Closing coil 16 to be energized, armature 6 drives latching valve spool 2 and push rod 7 to move to closed position, and check valve is at spring 14
Active force under be closed；Closing coil 16 power-off, armature 6 keeps under the permanent magnetic effect of locking magnet ring 5
In closed position, so that latching valve and check valve are held in closed position, such high pressure unidirectional self-lock valve is cutting out
Time seal the outer sealing function adding one and being made up of check valve except latching valve.
It is embodied as the integrated design using latching valve with check valve, it is achieved that the linkage of the two, has the advantage that
Have a state maintaining body, it is not necessary to power supply provides energy that valve opening just can be kept to obtain the steady operation shape of closedown
State；During valve opening, check valve is not closed with pressure change；During valve closing in addition to latching valve seals, also add one
The sealing function that road is made up of check valve.The present invention has latching valve and check valve double sealing, and simple in construction, power consumption
Low, can be widely used among the propulsion system of spacecraft.
Above the specific embodiment of the present invention is described.It is to be appreciated that the invention is not limited in above-mentioned spy
Determining embodiment, those skilled in the art can make various deformation or amendment within the scope of the claims, this not shadow
Ring the flesh and blood of the present invention.
