Abstract
The utility model is related to a kind of three adjusting ring safety valves, including valve body, valve seat, flap, valve deck, valve rod, pressure setting mechanism, its pressure setting mechanism by between valve rod and valve deck spring and adjusting screw rod form, Disc holder is set on the outside of valve clack sealing surface；Lift and blow pressure micromatic setting are equipped with mainly on Disc holder, the Lift and blow pressure micromatic setting by Disc holder radiai adjustment hole and flow-rate adjustment circle form, flow-rate adjustment circle is by being threadably mounted at the periphery in Disc holder radiai adjustment hole, from adjusting screw thread with the adjusting screw on valve body, radiai adjustment hole is connected to the periphery of flow-rate adjustment circle with Disc holder endoporus lower face.By adjusting the position of flow-rate adjustment circle, changes the aperture in radiai adjustment hole, control fluid release amount of the Disc holder lower face from radiai adjustment hole, the adjusting of Lift and blow pressure, control accuracy are high.
Description
Technical field
The utility model belongs to valve field, especially with respect to a kind of spring loaded safety valve.
Background technology
The structure of spring loaded safety valve is generally by valve body, valve seat, flap, valve deck, valve rod, pressure setting mechanism, pressure
Setting mechanism by between valve rod and valve deck spring and adjusting screw rod form, valve rod lower end top pressure is in flap back center
Locate, has in flap lower face and be fixed in valve body with sealing with the mutually matched sealing surface in valve seat upper surface, flap periphery
The dynamic cooperation of the guide sleeve of chamber.In order to adjust the Lift and blow pressure of flap, adjusted using being arranged on the outside of sealing surface of seat
Pitch circle, and Disc holder is set on the outside of valve clack sealing surface, Disc holder is by being threadably mounted at guide sleeve periphery, by its periphery
The height for adjusting screw thread and adjusting Disc holder with the adjusting screw on the valve body, control the Lift of flap.It is main
The disadvantage is that after the upper and lower displacement of Disc holder adjusts variation, cause fluid to the Lift of flap and blow pressure amplitude of variation compared with
Greatly, relatively low to the adjusting of flap Lift and blow pressure, control accuracy.
Invention content
The purpose of this utility model is to be directed to disadvantage of the existing technology, provides a kind of flap Lift and returns seat pressure
The three adjusting ring safety valves that power is adjusted, control accuracy is high.
The technical solution of the utility model includes valve body, valve seat, flap, valve deck, valve rod, pressure setting mechanism, pressure
Setting mechanism by between valve rod and valve deck spring and adjusting screw rod form, valve rod lower end top pressure is in flap back center
Locate, has in flap lower face and be fixed in valve body with sealing with the mutually matched sealing surface in valve seat upper surface, flap periphery
The dynamic cooperation of the guide sleeve of chamber, adjusting ring is arranged on the outside of sealing surface of seat, Disc holder is arranged on the outside of valve clack sealing surface；Mainly
Lift and blow pressure micromatic setting are equipped on Disc holder, the Lift and blow pressure micromatic setting are by recoiling
Radiai adjustment hole on disk and flow-rate adjustment circle composition, flow-rate adjustment circle is by being threadably mounted at the outer of Disc holder radiai adjustment hole
Disc, the periphery of flow-rate adjustment circle are coordinated from adjusting screw thread and the adjusting screw on valve body, radiai adjustment hole with instead
Punch plate endoporus lower face is connected to.
The utility model has the advantages that Lift and blow pressure micromatic setting are arranged on Disc holder, flowed by adjusting
The position of adjusting ring is measured, the aperture in radiai adjustment hole is changed, controls fluid release amount of the Disc holder lower face from radiai adjustment hole,
Realization accurately controls flap Lift and blow pressure, and the adjusting of Lift and blow pressure, control accuracy are high.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
Three adjusting ring safety valves as shown in Figure 1, including valve body 1, valve seat 2, flap 3, valve deck 10, valve rod 9, pressure setting
Mechanism, pressure setting mechanism by between valve rod 9 and valve deck 10 spring 11 and adjusting screw rod 12 form, under valve rod 9
It holds top pressure at 3 back center of flap, has and the mutually matched sealing surface in 2 upper surface of valve seat, flap 3 in 3 lower face of flap
The dynamic cooperation of guide sleeve 8 that periphery is fixed on 1 inner cavity of valve body with sealing is situated between when 2 inlet pressure of valve seat is more than 11 pressure of spring
Matter pressure pushes flap 3 to open, and adjusting ring 4 is arranged on the outside of 2 sealing surface of valve seat, adjusts medium flow direction when flap 3 is opened, control
To flap 3, to upthrust, Disc holder 5, the Disc holder 5 and 8 periphery of guide sleeve is arranged in medium processed on the outside of 3 sealing surface of flap
It is threadedly coupled, the screw thread on 5 periphery of Disc holder forms 5 displacement adjustment device of Disc holder with the adjusting screw on valve body 1；Anti-
Punch plate 5 is equipped with Lift and blow pressure micromatic setting, and the Lift and blow pressure micromatic setting are by Disc holder 5
On radiai adjustment hole 7 and flow-rate adjustment circle 6 form, flow-rate adjustment circle 6 is by being threadably mounted at the radiai adjustment hole 7 of Disc holder 5
The periphery at place, the periphery of flow-rate adjustment circle 6 from adjusting screw thread with the adjusting screw on valve body 1, adjust by radial direction
Knothole 7 is connected to 5 endoporus lower face of Disc holder, by adjusting the upper and lower position of flow-rate adjustment circle 6, changes radiai adjustment hole 7
Aperture, controls fluid release amount of 5 lower face of Disc holder from radiai adjustment hole 7, and realization accurately controls 3 Lift of flap and returns
There are several to be uniformly distributed along 5 circumferencial direction of Disc holder for seat pressure, radiai adjustment hole 7.
