Abstract
A tensile failure protection device comprises two mutually-butted check valves. Closure plates are installed in the valve cavities of the check valves, the inner edge of a counter flange is provided with seal edge notches, the outer edges of the closure plates are provided with binding faces, end face sealing devices are arranged at the binding faces, the front portions of the closure plates are provided with ejector rods, the rear portions of the closure plates are provided with guide rods installed on filtering brackets, the filtering brackets are provided with guide sleeves, and reset springs are arranged between the guide sleeves and the closure plates. When the two check valves are broken, the closure plates can be ejected through the reset springs, and the binding faces arranged on the outer edges of the closure plates are in cooperation with the seal edge notches formed in the inner edge of the counter flange for sealing; therefore, the leakage of fluid media is avoided, good sealing performance is guaranteed, and fast sealing is achieved when the check valves are broken. By the utilization of fast strutting mechanisms arranged at one end of a left beam clamp and one end of a right beam clamp, damage to equipment is avoided when the check valves are broken, and therefore the functions of safe breaking and closure protecting are achieved.

The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of fender guard of breaking, comprise two check valves of docking mutually, joint at two check valves is provided with plain flange, be set with a left side outside plain flange, right anchor ear, left, one end of right anchor ear is hinged by pipe link, on a left side, the other end of right anchor ear is provided with quick spreading mechanism, be characterized in: in the valve pocket of check valve, shrouding is installed, inner edge at plain flange is provided with the sealing bead coordinated with shrouding, be provided with the binding face coordinated with the sealing bead of plain flange on the outer rim of shrouding, at binding face, place is provided with face seals, back down the push rod of shrouding while being provided with two check valve docking in the front portion of shrouding, be provided with the pilot bar arranged vertically at the rear portion of shrouding, pilot bar is contained on filter holder, filter holder is connected with the inwall of check valve, be provided with the orienting sleeve coordinated with pilot bar on filter holder, be provided with the retracing spring be sleeved on pilot bar between orienting sleeve and shrouding.
The technical problems to be solved in the utility model can also be come further to realize by the following technical programs, described quick spreading mechanism comprises tapered pin and is arranged on the lockable mechanism of anchor ear end, left and right, lockable mechanism comprises the U-shaped groove that is located at one of them anchor ear end, another anchor ear end is provided with the inserted block be plugged in above-mentioned U-shaped groove, lockable mechanism is provided with the taper hole that runs through U-shaped groove and inserted block, tapered pin is contained in above-mentioned taper hole, small end at tapered pin is equipped with safety pin, large end at tapered pin is connected with stay cord, between the anchor ear of the left and right of lockable mechanism root, Compress Spring is housed.
The technical problems to be solved in the utility model can also be come further to realize by the following technical programs, be equipped with external flange at two check valves away from the end of interface, near on the check valve external flange of large end one side of tapered pin, being provided with positioning plate, be provided with the through hole that stay cord passes through on positioning plate.
Compared with prior art, the utility model utilization is arranged on the retracing spring between orienting sleeve and shrouding, can when two check valves disconnect, shrouding be ejected, make to be arranged on the binding face on the shrouding outer rim and be arranged on the sealing bead fitted seal on the plain flange inner edge, avoided the leakage of fluid medium, guarantee good leak tightness, realized fast sealing when check valve disconnects; Utilization is arranged on the quick spreading mechanism of left and right anchor ear one end, and the destruction while having avoided disconnecting, equipment produced has been realized the function of safe disconnection throttling protection.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
The left view that Fig. 2 is Fig. 1.
The specific embodiment
A kind of fender guard of breaking, comprise two check valves 1 of docking mutually, 4, at two check valves 1, 4 joint is provided with plain flange, be set with a left side outside plain flange, right anchor ear 14, 15, left, right anchor ear 14, an end of 15 is hinged by pipe link 2, on a left side, right anchor ear 14, 15 the other end is provided with quick spreading mechanism, shrouding 11 is installed in the valve pocket of check valve, inner edge at plain flange is provided with the sealing bead coordinated with shrouding 11, be provided with the binding face coordinated with the sealing bead of plain flange on the outer rim of shrouding 11, at binding face, place is provided with face seals, back down the push rod 3 of shrouding while being provided with two check valve docking in the front portion of shrouding 11, be provided with the pilot bar 5 arranged vertically at the rear portion of shrouding 11, pilot bar 5 is contained on filter holder 7, filter holder 7 is connected with the inwall of check valve, be provided with the orienting sleeve 6 coordinated with pilot bar 5 on filter holder 7, be provided with the retracing spring 12 be sleeved on pilot bar 5 between orienting sleeve 6 and shrouding 11.This equipment is mainly to solve oil transfer arm when ejection escape, guarantees safety disengagement and the sealing of two check valves at the interface place, can not produce and destroy apparatus body, realizes disconnecting and playing safely the function of throttling protection.
Described quick spreading mechanism comprises tapered pin 9 and is arranged on the lockable mechanism of anchor ear end, left and right, lockable mechanism comprises the U-shaped groove that is located at one of them anchor ear end, another anchor ear end is provided with the inserted block be plugged in above-mentioned U-shaped groove, lockable mechanism is provided with the taper hole that runs through U-shaped groove and inserted block, tapered pin 9 is contained in above-mentioned taper hole, small end at tapered pin 9 is equipped with safety pin 8, at the large end of tapered pin 9, is connected with stay cord 10, between the anchor ear of the left and right of lockable mechanism root, Compress Spring 16 is housed.Be equipped with external flange at two check valves away from the end of interface, near on the check valve external flange of large end one side of tapered pin, being provided with positioning plate 13, be provided with the through hole that stay cord passes through on positioning plate 13.When needs disconnect two check valves, pull stay cord 10, extract tapered pin 9, cut off safety pin 8, by the tension force of Compress Spring 16 and the gravity of left and right anchor ear, open anchor ear, realize the disengaging of two anchor ears, simultaneously, shrouding, under the effect of retracing spring, seals exit end immediately, has avoided the leakage of medium.
