Description
Technical field
The utility model belongs to aircraft environmental control system separator technical field, and in particular to a kind of new type of safe valve
Locking mechanism.
Background technology
The supporting safety valve structure of raw water separator is as shown in figure 1, including valve body 1, valve 2, spring 3, lower spiral shell
, be locked to clamp nut 5 on valve body 1 by 4 punching points by female 4, clamp nut 5.
The valve structure lower nut 4 is not completely fixed, and spring impulsive force is delivered to pressure by lower nut 4 in use
On tight nut 5, punching point abrasion is easily caused, clamp nut 5 loosens, inner body comes off so as to cause.
Utility model content
The purpose of this utility model：Safety valve is improved, is carried out using new locking mode locking.
Technical solutions of the utility model：A kind of new type of safe valve locking mechanism, including valve body 1, valve 2, spring
3rd, lower nut 4, clamp nut 5, sunk screw 6, pad 7, the inwall of valve body 1 have boss structure, spring 3 are cased with valve 2,
Lower nut 4 coordinates the positioning at boss with the inner thread of valve body 1, and the afterbody of valve 2 passes through the pilot hole of lower nut 4, bullet
The head end thereof contacts lower nut 4 of the end thereof contacts valve 2 of spring 3, clamp nut 5 coordinates compression lower nut with the inner thread of housing 1
4, be fixed on clamp nut 5 in housing 1 by the clamp nut 5 circumference uniform distribution, 4 sunk screws 6, clamp nut 5 and countersunk head spiral shell
Nail 6 is welded to connect.
Pad 7 is provided with the inner portion of the valve 2, the quantity of the pad 7 adjusts the pressure of spring 3, determines valve 2
Opening pressure.
The beneficial effects of the utility model：The reliability of safety valve greatly improved.
Brief description of the drawings
Fig. 1 is：Former safety valve structure；
Fig. 2 is：Safety valve structure chart after improvement.
Specific embodiment
A kind of new type of safe valve locking mechanism, including valve body 1, valve 2, spring 3, lower nut 4, clamp nut 5,
Sunk screw 6, pad 7, it is characterised in that：The inwall of valve body 1 has boss structure, is cased with spring 3 on valve 2, lower nut 4 with
The inner thread of valve body 1 coordinates the positioning at boss, and the afterbody of valve 2 passes through the pilot hole of lower nut 4, spring 3 one to terminate
The head end thereof contacts lower nut 4 of valve 2 is touched, clamp nut 5 coordinates compression lower nut 4, the compression with the inner thread of housing 1
Be fixed on clamp nut 5 in housing 1 by nut 5 circumference uniform distribution, 4 sunk screws 6, and clamp nut 5 is welded with sunk screw 6 and connected
Connect.
Pad 7 is provided with the inner portion of the valve 2, the quantity of the pad 7 adjusts the pressure of spring 3, determines valve 2
Opening pressure.
