Zusammenfassung: | The invention relates to a device for rapidly closing a valve, particularly a valve mounted on a pipe-line for feeding methane gas or any other fluids and subjected to seismic forces. According to the invention, the closing device comprises a housing (2) closed by a lower cover (3) and an upper cover (4) by means of some screws (5 and 6), the ball valve (A) being fixed by means of a clip (7) and some screws (8) to the lower cover (3), on the driving rod (1) of the ball valve (A), a plate (9) and a support (10) of an annular lever (11) being mounted by pressing, by means of a nut (12), the annular lever (11) being mounted in the support (10) by means of an axle (13), on an arm (a) of the annular lever (11) there being mounted, by means of an axle (14), a lock (15) passing through the plate (9) and penetrating into an orifice (b) drilled in the lower cover (3), due to the pressure exerted by a helical spring (16), a stopper screw (17) being fastened in the plate (9), said limiting screw passing through a slot (c) cut in the housing (2), in said housing (2) there being introduced a driving helical spring (18) which has some noses (d and e) bent axially at 90° and fastened in an orifice (f) drilled in the upper cover (4) and in an orifice (g) drilled in the plate (9), in the upper cover (4) there being fastened some rods (19) for guiding a pendulum (20) leaning on a helical spring (21) by means of an adjusting screw (22).
Invenţia se referă la un dispozitiv de închidere rapidă a unui robinet, în special a unui robinet montat pe o conductă de alimentare cu gaz metan sau orice alte fluide, acţionat de forţe seismice. Dispozitivul pentru închidere, conform invenţiei, are o carcasă (2) închisă de un capac (3) inferior şi un capac (4) superior, cu ajutorul unor şuruburi (5 şi 6), robinetul (A) cu sferă fiind fixat cu ajutorul unui colier (7) şi al unor şuruburi (8) pe capacul (3) inferior, pe tija (1) de acţionare a robinetului (A) cu sfera, se fixează prin presare un platou (9) şi un suport (10) al unei pârghii (11) circulare, cu ajutorul unei piuliţe (12), pârghia (11) circulară este montată în suport (10) prin intermediul unui ax (13), pe un braţ (a) al pârghiei (11) circulare, este montat, cu ajutorul unui ax (14), un zăvor (15) care trece prin platou (9) şi pătrunde într-un orificiu (b) practicat în capacul (3) inferior, datorită presiunii exercitate de un resort (16) elicoidal, în platou (9), se fixează un şurub (17) limitator, care trece printr-o fantă (c) p |
