- said second spring is constituted by a stack of deformable washers, arranged on a push rod forming part of said second control mechanism, the stack being in abutment between a fixed point and a shoulder of said rod.
- the force developed by the second spring is significantly greater than that developed by the first.
- valve stroke under the bias of the first spring is important, of the order of 180 °, to clear the seat completely and avoid disturbing your vein fluid.
- the stroke of the locking finger under the bias of the second spring is lower, of the order of 30 ° and this stroke is kinematically offset from that of the valve so that the locking finger cooperates with the valve that end of closing race of it.
- the locking finger is released first.
- the synchronization of the two kinematics, the valve on the one hand and the locking finger on the other hand results from the arrangement of the first and second control mechanisms, as will be seen below, which comprise a rod of common actuation.
- said first axis is attached to a first lever coupled to said actuating rod with a predetermined play in the longitudinal direction thereof.
- FIG. 1 is an external rear left perspective view of the valve in the closed position
- Figure 2 is a view similar to Figure 1 illustrating the valve in the open position
- FIG. 3 is a view similar to Figure 1, the hood being removed;
- FIG. 4 is a view similar to Figure 2, the hood being removed;
- FIG. 5 is a rear right rear perspective view of the valve in the open position, the hood being removed;
- FIG. 6 is a section VI-VI of FIG. 4;
- Figure 7 is a section VII-VII of Figure 1;
- FIG. 8 is a section VIII-VIII of Figure 2.
- the isolation valve 11, according to the invention seen from the inside, that is to say mounted on a wall 12 which can itself be installed on a fuel tank rocket or be part of it.
- the valve body 14 here comprises a tubular connection section 16, according to the example perpendicular to the wall 12 and attached thereto.
- the section 16 opens outward, that is to say on the other side of the wall 12, for its connection to a complementary end piece (not shown) forming part of a ground filling or emptying equipment. propellant tanks of the rocket.
- connection portion The free end, inside, of this connection portion forms a seat 18 for a valve 20.
- This valve is of the swing type, pivotally mounted along a first axis 22 adjacent to the seat.
- the axis is perpendicular to an axial direction X of the connection section 16 and, according to the example, parallel to the wall 12.
- the valve 20 comprises an arm 24 integral in rotation with the axis 22, which is articulated between two parallel flanges 26, forming a clevis, of the valve body.
- Two sealing plates 27 are fixed respectively to the two flanges, outside the yoke.
- the valve is equipped with a seal 30 which comes into contact with the seat 18 in the closed position.
- a first control mechanism 32 is coupled to the valve 20 for opening and closing thereof. More specifically, this mechanism comprises, on one side of the yoke (26-26), a first helical spring 34 mounted to urge the valve towards its closed position. On the other side of the yoke, the mechanism comprises a first lever 36 integral with the shaft 22 and coupled to an actuating rod 38 movable perpendicularly to the wall 12.
- the coil spring 34 is mounted on said first axis 22 and fixed between it and a fixed point.
- one end of the spring may be attached to the wall 12 and the other end 34a may be attached to the axis 22.
- the shaft 22 is extended as a larger portion. diameter accommodating the spring and said other end 34a of said spring is bent and engaged in a notch of this part.
- Said first lever 36 is coupled to said actuating rod 38 with a predetermined play in the longitudinal direction thereof.
- said first lever comprises a pin 40 engaged in a longitudinal slot 42 of the actuating rod.
- the system also comprises a locking pin 45 pivotally mounted along a second axis 47 adjacent the seat and perpendicular to said axial direction X of the connection section 16.
- the kinematics of the locking pin 45 is defined by a second control mechanism 48 designed to cause it to be applied against the valve 20 in the closed position.
- the locking finger 45 confirms the application of the valve 20 on its seat 18, which reinforces the sealing of the isolation valve 11, the application force developed by the locking finger 45 being significantly greater than the biasing force applied to the valve to bring it to its seat 18.
- said second control mechanism comprises a second spring 50 mounted for biasing the locking finger 45 in abutment against the valve 20 in the closed position.
- the developed force by this second spring 50 is significantly greater than the biasing force developed by the first spring 34.
- the second spring 50 is constituted by a stack of deformable washers 50a (for example Belleville washers) engaged on a push rod 52 forming part of said second control mechanism 48.
- the stack is in abutment between a point fixed, typically the wall 12 and a shoulder 54 of the rod.
- the second axis 47 is rotatably mounted between two parallel flanges 56 defining a yoke.
- the locking finger 45 integral with the second axis 47 pivots inside this yoke.
- Two sealing plates 49 are fixed respectively to the two flanges outside the yoke (56-56). It is seen that the two clevises, maintain the two axes 22, 47, (that of the valve and that of the locking finger) on either side of the seat 18.
- the two axes are parallel.
- the two aforementioned screeds are defined in a molded or machined part forming part of a support fixed to the wall 12 and surrounding the connection section 16. This support comprises a joint plane on which a cover 58 is fixed.
- Said cover includes the valve 20 and the locking finger 45 without hindering their strokes.
- This cover comprises an outlet orifice 60 and a lateral extension 62 pierced with a guide hole 63 in which the rod 38 slides.
- the second control mechanism 48 comprises a gear system extending between the push rod and the second axis 47, outside the yoke (56-56).
- This gear system comprises a pinion gear 64 rotatably mounted on a fixed pin 66 and a pinion 68 fixed to the end of the pin 47 and engaged with the pinion 64.
- This pinion 68 drives the pin and consequently the pinion. locking finger, rotating.
- the rod 52 has a rounded end in contact with a recess of the pinion 64.
- said second axis 47 is fixed to a second lever 70 and the actuating rod 38 carries a cam 72.
- the end of the second lever 70 is in contact with this cam whose profile determines the kinematics of the finger 45.
- the end of the second lever is provided with a freely rotating roller 74 in contact with the cam.
- first and second control mechanisms 32, 48 comprise a common element, namely the rod
- the position of the light 42 relative to the cam 72 and the profile of the latter conditions the respective kinematics of the valve 20 and the locking pin 45 as well as the synchronization of the two movements.
- the first lever 36 When the first lever 36 comes into contact with the end of the light 42, it begins to pivot, which causes the opening of the valve 20 and its complete clearance relative to the seat 18.
- the filling can be performed without loss of load due to the valve.
