Description
Technical field:
The present invention relates to a kind of pipeline locking-valve, especially a kind of pipeline locking-valve of carrying magnetic lock.
Background technique:
The present various valve products that have magnetic lock, valve links to each other with magnetic lock, opens and closes by the magnetic lock control valve, exposes design and the key operated part of magnetic lock is most for protruding, twisted off by force by instruments such as spanners easily or be out of shape, cause valve to damage.
The key operated part of the magnetic lock valve that has adopts the indent setting, and by being arranged at the switching of the jack cooperation interpolation type key control valve in the valve body, the shortcoming of the method is that the interpolation type key may damage owing to torsion is excessive when manifold pressure is excessive.
Summary of the invention:
The technical problem to be solved in the present invention provides a kind of safe and reliable, pick-proof, high strength, magnetic lock valve simple to operation.
For solving the problems of the technologies described above, locking-valve of the present invention comprises valve body, valve rod, and the valve ball in the valve body is controlled by valve rod, and the magnetic lock valve of valve rod and may command valve rod motion links;
Magnetic lock comprises lock housing, locking bolt, tower spring, dead bolt and flexible handle, and locking bolt and valve rod upper end contacts, and flexible handle is located at corresponding trepanning of locking bolt upper end size and locking bolt socket by interior, and flexible handle drives valve rod by locking bolt and rotates, the realization valve opening;
Described dead bolt is embedded in the locking bolt, and dead bolt is made up of magnet steel and returning spring, by the contraction realization of returning spring and engaging of lock-shell lining flange;
Described flexible handle madial wall and dead bolt magnet steel relevant position are embedded with permanent-magnet steel.
Adopt said structure, because flexible handle is located at corresponding trepanning of locking bolt upper end size and locking bolt socket by interior, flexible handle drives the valve rod rotation by locking bolt, thereby has guaranteed between valve rod and valve, the locking bolt enough shearing stresses are arranged, therefore have higher intensity, simple to operation.
Between magnet steel on the above-mentioned flexible handle madial wall and the dead bolt magnet steel is corresponding setting, be provided with the magnet steel of two diverse locations on the flexible handle madial wall at least, and the dead bolt magnet steel polarity on the corresponding position is consistent with flexible handle.When flexible handle and locking bolt socket, owing to the same sex is repelled each other, dead bolt magnet steel compression reaction spring, disengaging engages with the lock-shell lining flange; When returning spring in the raw the time, the dead bolt magnet steel engages with the lock-shell lining flange.The correspondence if differ in their quantity and position then can't realize release, and because the position of magnet steel can conversion, the quantity of magnet steel can increase and decrease, so the technical program has Security preferably.
Above-mentioned lock housing top is concordant with the locking bolt that is in when locking; the lock housing bottom is by the annular groove clamping of bearing pin and valve body upper end; so when being in locking; locking bolt does not have exposed parts; and lock housing can make the instrument of adding such as spanner be difficult to find force bearing point along the design that annular groove rotates; and then protected locking bolt and valve rod, improved the pick-proof performance.
As a further improvement on the present invention, the polygonal design is adopted on above-mentioned locking bolt top, makes and the socket of adjustable spanner close and firm more, has increased the reliability of valve opening.
In sum, the invention has the advantages that safe and reliable, simple to operation and have pick-proof, advantages of high strength.
Description of drawings:
Fig. 1 is the structural representation that locking-valve is in released state,
Fig. 2 is the structural representation that locking-valve is in the lock state,
Fig. 3 is the flexible handle structural representation of locking-valve.
Embodiment:
Fig. 1, Fig. 2, Fig. 3 are one embodiment of the present of invention.
Referring to Fig. 1, locking-valve of the present invention comprises valve body 1, valve rod 2 and magnetic lock 3, and valve rod 2 stretches out valve body 1, and the valve ball in the valve body 1 is subjected to valve rod 2 regulation and control, and valve rod 2 links with the magnetic lock 3 of control stem movement.
Magnetic lock 3 comprises lock housing 4, locking bolt 5, tower spring 6, dead bolt 7 and flexible handle 8, locking bolt 5 contacts with valve rod 2, and flexible handle 8 is located at corresponding trepanning 8-1 of locking bolt upper end 5-1 size and locking bolt 5 sockets by interior, flexible handle 8 drives valve rod 2 by locking bolt 5 and rotates, and realizes the unlatching of valve.
Described dead bolt 7 is made up of dead bolt magnet steel 7-1 and returning spring 7-2, is embedded among the groove 5-2 of locking bolt 5, slides along groove 5-2, by the contraction answer realization of returning spring 7-2 and engaging and disengaging of lock housing 4 inwall flange 4-1.
Described lock housing 4 bottoms are by annular groove 10 clampings of bearing pin 9 with the valve body upper end, and lock housing 4 can be rotated along annular groove 10 after the clamping, and force bearing point can not utilize owing to have fixedly so add instrument, and valve body 1, valve rod 2 are difficult for being damaged.
As Fig. 1, shown in Figure 3, described flexible handle 8 is made up of collar 8-1 and handle 8-2, is embedded with permanent-magnet steel 8-3 on the collar 8-1 madial wall, and present embodiment has adopted 2 asymmetric settings of permanent-magnet steel 8-3; The dead bolt magnet steel 7-1 position that is embedded in the locking bolt 5 is corresponding one by one with permanent-magnet steel 8-3 on the flexible handle 8, and dead bolt magnet steel 7-1 polarity is consistent with the permanent-magnet steel 8-3 on the flexible handle 8; When flexible handle 8 socket lock housing top 4-2, it is consistent that the dead bolt magnet steel 7-1 position of its permanent-magnet steel 8-3 when being in the lock state is in level.
As shown in Figure 2, with valve regularly, push locking bolt upper end 5-1, tower spring 6 shrinks, when dead bolt 7 was concordant with lock housing 4 inwall flange 4-1, returning spring 7-2 replied nature, promoted dead bolt magnet steel 7-1 and slided along groove 5-2, and then with lock housing 4 inwall flange 4-1 snap lock, at this moment, 5-1 position, locking bolt upper end is just in time concordant with lock housing top 4-2, so add instrument owing to there is not stress action spot, be difficult to destroy locking bolt 5, embodied good pick-proof performance.
As shown in Figure 1, during with the valve release, with flexible handle 8 sockets and lock housing top 4-2, dead bolt magnet steel 7-1 is owing to influenced by the repulsion of flexible handle permanent-magnet steel 8-3, returning spring 7-2 is compressed, when dead bolt magnet steel front portion breaks away from lock housing flange 4-1, push locking bolt upper end 5-1, tower spring 6 promotes locking bolt 5 and rises, the trepanning 8-1 of locking bolt upper end 5-1 and flexible handle 8 realizes socket, rotates the handle 8-2 of flexible handle 8 this moment, and flexible handle 8 drives locking bolt 5 and rotates, locking bolt 5 is realized the switching of valve by driving the rotation that valve rod 2 rotates valve ball.
As the further improvement of this locking-valve, anistree cylindrical design is adopted on locking bolt top, and the trepanning 8-1 of the flexible handle 8 of Pei Heing also adopts corresponding octagon design with it.
The present invention is not limited to above-mentioned mode of execution; no matter the position of permanent-magnet steel and quantitatively do any variation on the flexible handle everyly utilizes that the polar repulsion principle of permanent-magnet steel and dead bolt magnet steel realizes that the locking-valve of sealed disengaging all drops within the protection domain of the present invention on the flexible handle.In addition, the outer polygon cylindricality of octagon is adopted on locking bolt top, and perhaps dead bolt returning spring, tower spring adopt other elastic components such as reed, all should think within protection domain of the present invention.
