Abstract
The utility model is related to a kind of variable displacement safety valves, including valve body, valve seat, flap, valve rod, valve deck, pressure setting mechanism, flap is fixedly mounted in Disc holder lower face, pressure setting mechanism by between valve rod and valve deck spring and adjusting screw rod form, the guide post of the back side up extension of Disc holder and the dynamic cooperation of guide sleeve endoporus, valve rod lower end top pressure is in the centre bore of guide post；Displacement adjusting mechanism mainly is set on the guide sleeve at the Disc holder back side, the displacement adjusting mechanism is made of adjusting set and adjusting screw, adjusting set is connected to by internal thread on the external screw thread of guide sleeve lower part, adjusting set periphery, which is formed with, to be mounted on the mutually matched external screw thread of adjusting screw, adjusting screw on valve body.The height that adjusting set is adjusted by adjusting screw, realizes the adjusting of discharge capacity, can be needed manual adjustment discharge capacity, adaptability good according to operating mode.
Description
Technical field
The utility model belongs to valve field, especially with respect to a kind of spring loaded safety valve.
Background technology
Spring loaded safety valve is generally made of valve body, valve seat, flap, valve rod, valve deck, pressure setting mechanism, and pressure is whole
Determine mechanism by between valve rod and valve deck spring and adjusting screw rod form, in flap lower face have and valve seat upper surface
Mutually matched sealing surface, is arranged Disc holder on the outside of valve clack sealing surface, increases the Lift of flap, and Disc holder is back side up
The guide post of extension and the dynamic cooperation of guide sleeve endoporus, valve rod lower end top pressure is in the centre bore of guide post.When valve body import medium
When pressure is more than set-pressure value, flap is opened pressure of releasing, and application valve body inlet pressure is in safe range.Its major defect
Discharge capacity of releasing when being safety valve unlatching cannot need be adjusted according to operating mode.
Invention content
The purpose of this utility model is to be directed to disadvantage of the existing technology, and providing one kind can be opened by controlling Disc holder
Height is opened, discharge capacity of releasing, adaptable variable displacement safety valve are adjusted.
The technical solution of the utility model includes valve body, valve seat, flap, valve rod, valve deck, pressure setting mechanism, and flap is solid
Dingan County is in Disc holder lower face, and pressure setting mechanism is by the spring and adjusting screw rod group between valve rod and valve deck
At guide post and the dynamic cooperation of guide sleeve endoporus, centre bore of the valve rod lower end top pressure in guide post of the back side up extension of Disc holder
It is interior；Displacement adjusting mechanism is mainly set on the guide sleeve at the Disc holder back side, and the displacement adjusting mechanism is by adjusting set and tune
Screw composition is saved, adjusting set is connected to by internal thread on the external screw thread of guide sleeve lower part, and adjusting set periphery is formed with and adjusts spiral shell
Mutually matched external screw thread is followed closely, adjusting screw is mounted on valve body.
The utility model has the advantages that displacement adjusting mechanism is arranged on the guide sleeve at the Disc holder back side, pass through adjusting screw
The height for adjusting adjusting set, realizes the adjusting of discharge capacity, can be needed manual adjustment discharge capacity, adaptability good according to operating mode.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
Variable displacement safety valve as shown in Figure 1, including valve body 1, valve seat 2, flap 3, valve rod 8, valve deck 9, pressure setting
Mechanism, flap 3 are fixedly mounted in 4 lower face of Disc holder, and pressure setting mechanism is by the bullet between valve rod 8 and valve deck 9
Spring 10 and adjusting screw rod 11 form, guide post and the dynamic cooperation of 7 endoporus of guide sleeve, 8 lower end of valve rod of 4 back side up extension of Disc holder
In the centre bore of guide post, 7 upper end of guide sleeve is sealingly mounted between valve deck 9 and valve body 1 top pressure；At 4 back side of Disc holder
Displacement adjusting mechanism is set on guide sleeve 7, the displacement adjusting mechanism is made of adjusting set 6 and adjusting screw 5, adjusting set 6 by
Internal thread is connected on the external screw thread of 7 lower part of guide sleeve, and 6 periphery of adjusting set is formed with and the mutually matched outer spiral shell of adjusting screw 5
Line, adjusting screw 5 are mounted on valve body 1, by adjusting screw 5 adjust between adjusting set 6 and 4 back side of Disc holder it is opposite away from
From the Lift of limitation Disc holder 4 adjusts drawoff discharge, and 6 lower end of adjusting set has circle corresponding with 4 back side of Disc holder
Plane.
