Flap head and valve rod are constituted, and valve rod one end is connected with described lever, is slidably matched with described housing in the middle part of valve rod；Valve rod another
End and pass through with flap head that flexural pivot structure is hinged, this flexural pivot structure includes the first half ball-and-socket, bulbs and has second
The hemisphere cover of half ball-and-socket, the first half ball-and-sockets are formed on the inner face of described flap head, and bulb is formed at institute by bulb axle journal
State valve rod front end；Hemisphere cover is sleeved on described bulb axle journal by backend space, outside the disc that hemisphere cover is formed by front end
Flange is welded and fixed with described flap head.
Using this utility model of preceding solution, actuator is used for by the fluid outlet being located at valve port, by changing
Become the rate-of flow that the realization of the distance and between valve port end face is flowed out by valve port, reach the purpose of pressure adjustment.Due to valve manufacture
And alignment error, flap and valve port certainly exist certain bias, therefore, during flap exits closing mouth, act on valve
Fluid pressure on lobe head is inevitable to form non-uniform Distribution in flap end surface；Wherein, flap head forms ball pivot with valve rod and is connected
Relation, therefore, under uneven Fluid pressure acts on, flap head is askew with respect to the deflection that the valve rod of guiding forms certain angle
Tiltedly, fluid matasomatism can make dust on sealing gasket, dirt be purged, thus realizing self-cleaning purpose on crooked sealing gasket.
The first half ball-and-sockets and the second half ball-and-sockets form the cooperation sphere of bulb, and the gap between bulb axle journal and hemisphere cover endoporus constitutes valve
Lobe head beat requisite space is it is ensured that flap head oscillating function is reliable.The second half ball-and-sockets are formed on hemisphere cover, and hemisphere cover is welded on
Flap head, its structure is simple, easy to process, low cost of manufacture, long service life.
Preferably, described hemisphere cover is made up of at least two lobes of circumference equal dividing.To install hemisphere cover from bulb end, improve
The convenience of assembling before weldering, improves working (machining) efficiency.
It is further preferred that described hemisphere cover is formed by plate stamping.High in machining efficiency, low cost of manufacture.
Preferably, the sealing surface of described flap head is provided with sealing gasket, and this sealing gasket passes through crossing distribution with flap head
Dovetail fit structure be connected together.To be cooperatively formed firmly by dovetail using the deformation behavior of sealing gasket and just to dismantle
Attachment structure, the sealing gasket being easy to rapid wear changes, and meanwhile, the dovetail fit structure of crossing distribution can ensure that the two is radially fixed
Position requires.
The beneficial effects of the utility model are that the flap of pressure regulator is in the combinative structure that ball pivot connects, in the course of the work
Automatic blowing cleaning is formed by gas medium, its structure is simple, self-cleaning function reliable, the voltage regulation result of pressure regulator is good, pressure regulation
Can be reliable.
