Abstract
The utility model is that flap can the low-temperature safety valve of automatic capturing, solves valve seat and is connected the processing that produces with valve body and assembly error affects the guide surface of flap and the correlation of sealing surface, cause the problem that safety valve is revealed.Flap (2) is the assemblying body be made up of flap seal (3), rotating shaft (4) and valve petal body (5), valve petal body is cylindrical shape, flap seal is embedded in bottom valve petal body, gap is had between the cup bottom plane of flap seal and valve petal body, rotating shaft diametrically axle is passed flap seal and is fixed on the downside wall of valve petal body, make flap seal physical efficiency to rotate in certain angle around rotating shaft, the rounded outer surface of valve petal body is guide surface.
Description
technical field:
The utility model is relevant with safety valve.
background technique:
Existing safety valve now, the sealing surface of flap and valve seat closes the effect that reaches safety valve closedown, therefore, except the smoothness requirements of flap and sealing surface of seat is higher, the more important thing is and require that the requirement of the perpendicularity of the guide surface of flap and sealing surface is also very high, and also can affect the guide surface of flap and the correlation of sealing surface because valve seat is connected with valve body the assembly error produced, be thus very easy to cause the situation that safety valve is revealed and Reseating pressure of a safety valve is on the low side to occur.Thus affect the working effect of low-temperature safety valve.
model utility content:
It is simple that the purpose of this utility model is to provide a kind of structure, can allow valve clack of safety valve automatic capturing, realize flap and valve seat is effectively closed can the low-temperature safety valve of automatic capturing with the flap reaching complete sealing effect.
The utility model realizes by the following method like this:
Valve seat 1 and flap 2 are sealed and matched, Adjusting bolt Adjusting screw 11 is connected with valve body 8 upper end internal thread, bonnet 9 is connected with valve body 8 upper external screw thread, spring 7 is enclosed between lower spring cup 6 on valve rod 10 and upper spring seat 9 in spring chamber, valve rod lower end is conical, coordinate with the conical surface of flap 2, valve rod upper end is positioned at Adjusting bolt Adjusting screw 11, flap 2 is by flap seal 3, the assemblying body that rotating shaft 4 and valve petal body 5 are formed, valve petal body 5 is cylindrical shape, flap seal 3 is embedded in bottom valve petal body 5, gap is had between the cup bottom plane of flap seal 3 and valve petal body 5, rotating shaft 4 diametrically axle is passed flap seal 3 and is fixed on the downside wall of valve petal body, flap seal 3 can be rotated in certain angle around rotating shaft 4, the rounded outer surface of valve petal body 5 is guide surface.
The utility model has the following advantages:
(1) effectively can guarantee effective laminating of valve clack of safety valve and sealing surface of seat, guarantee the fluent movements during work of safety valve, performance is precise and stable.
(2) structure is simple, produces assembling simply.
(3) rationally can reduce the difficulty of processing of flap and valve seat, effectively save production cost.
accompanying drawing illustrates:
Fig. 1 is structural drawing of the present utility model,
Fig. 2 is schematic enlarged-scale view of the present utility model.
embodiment:
Valve seat 1 and flap 2 are sealed and matched, Adjusting bolt Adjusting screw 11 is connected with valve body 8 upper end internal thread, bonnet 9 is connected with valve body 8 upper external screw thread, spring 7 is enclosed between lower spring cup 6 on valve rod 10 and upper spring seat 9 in spring chamber, valve rod lower end is conical, coordinate with the conical surface of flap 2, valve rod upper end is positioned at Adjusting bolt Adjusting screw 11, flap 2 is by flap seal 3, the assemblying body that rotating shaft 4 and valve petal body 5 are formed, valve petal body 5 is cylindrical shape, flap seal 3 is embedded in bottom valve petal body 5, gap is had between the cup bottom plane of flap seal 3 and valve petal body 5, rotating shaft 4 diametrically axle is passed flap seal 3 and is fixed on valve petal body downside wall, flap seal 3 can be rotated in certain angle around rotating shaft 4, the rounded outer surface of valve petal body 5 is guide surface.
The utility model flap can the low-temperature safety valve of automatic capturing, and flap 2 and valve seat 1 surface of contact are sealing surface, have little Xu small―gap suture between flap seal 3 and valve petal body 5, and flap seal 3 can be rotated around rotating shaft 4 in certain angle.
When safety valve because assembly error and processing reason etc. cause the guide surface of its flap 2 and valve seat 1 sealing surface perpendicularity to be affected, flap seal 3 can 4 rotate a certain angle automatically around the shaft, when making valve petal body 5 body skew not occur and rotate, the sealing surface of flap 2 still can be good at carrying out laminating one with the sealing surface of valve seat 1 and arrives good sealing effect.Make the open and close fluent movements of safety valve, stable performance, thus guarantee and safety.
