Abstract
The utility model relates to a safety valve for controlling fluid. The safety valve for controlling fluid is composed of a valve nut, a seat pad, a valve seat, a sealing member, a spring, a valve clack, a valve body, and a regulating nut. The spring is a butterfly shape spring. The inner hole of the spring is sheathed on a valve rod which is formed into an integral body with the valve clack. The shape of the inlet contact end of the valve clack and the valve seat is an inverted cone. The integral valve clack can not occur an advancing starting or hysteresis starting phenomenon.
Description
The utility model belongs to fluid control safety valve.
Traditional fluid control safety valve adopts common spring selecting for use of spring in the design.Since its poor stability, the leading or hysteresis that causes valve body to start, thus produce leakage phenomenon.
The purpose of this utility model is to propose a kind of fluid control safety valve technological scheme, addresses the above problem.
Fluid control safety valve of the present utility model is made up of valve mother, seat cushion, valve seat, Sealing, spring, flap, valve body, adjusting mother, and described spring is a butterfly spring, and its inner hole sleeve is on flap.Flap has the valve rod of one, and the inner hole sleeve of butterfly spring is on the valve rod of flap.Flap and valve seat inlet contact jaw be shaped as inverted cone.The inverted cone of flap matches with the valve seat entry end.
Characteristics of the present utility model are that employing is active in one's movements, the butterfly spring of reliable performance, and the bar portion that the core of spring is enclosed within flap is felt relieved by valve rod; Valve rod and flap one are placed in the butterfly spring, and it is synchronous to have guaranteed that pressure and flap are opened, and have avoided the lead and lag of valve events.
Embodiment of the present utility model is as shown in drawings:
Accompanying drawing is that master of the present utility model looks cross section view.
Number in the figure is represented:
1, valve mother, 2, valve pad, 3, valve seat, 4, the flap termination, 5, seal ring, 6, butterfly spring, 7, valve rod, 8, valve body, 9, regulate female, 10, hand-hole, 11, portal.
Accompanying drawing is specified the utility model in conjunction with the embodiments:
Valve rod 7 and flap termination 4 all-in-one-piece safety flaps.Butterfly spring 6 inner hole sleeves are on valve rod 7.Establish a seal groove on the flap, a seal ring 5 is set in the groove.Valve body 8 is threaded with regulating mother 9, and an end of regulating mother 9 is pressed in butterfly spring 6 upper ends, regulates the cracking pressure of safety valve.Flap 4 terminations become inverted cone to match with inlet 10.Valve female 1 is threaded with valve body 8, makes valve seat 3 seal embeddings by valve pad 2 and crouches in valve body 8.
Working condition of the present utility model is: when no pressure or pressure were less than spring pressure in the system, flap 4 had been pressed under the spring 6 pressure effects on the inlet 10, the sealing inlet.When inlet 10 pressure during greater than butterfly spring 6 pressure, lift unlatching on the flap, high-pressure liquid is discharged by outlet 11, simultaneously release pressure.System pressure during less than butterfly spring pressure flap seal inlet heavily again.Leading or retardation phenomenon can not take place to start in whole flap.
Claims (3)
1, a kind of fluid control safety valve is made up of valve mother, seat cushion, valve seat, Sealing, spring, flap, valve body, adjusting mother, it is characterized in that described spring is a butterfly spring, and its inner hole sleeve is on flap.
2, fluid control safety valve as claimed in claim 1 is characterized in that flap has the valve rod of one, and the inner hole sleeve of butterfly spring is on the valve rod of flap.
