For achieving the above object, the utility model provides following technological scheme: a kind of self-contained pressure regulator, include valve body, valve gap, be located at the medium inlet passage on valve body, the connection chamber of medium flow pass and connecting media inlet passage and medium flow pass, be provided with in connection chamber valve seat and can with the spool of valve base sealing, valve body is provided with the actuator of valve rod with valve spool and actuate valve stem, Sealing is provided with between valve rod and valve gap, it is characterized in that: described valve gap is added is provided with frame plate, actuator is the film chamber be set up on frame plate, diaphragm film chamber being divided into upper film chamber and bottom film chamber is provided with in film chamber, described valve rod to extend in lower mode cavity and is connected with diaphragm, upper film chamber is provided with the attachment hole be communicated with external pipe, described valve rod is arranged with Compress Spring, described Sealing includes the gland removably connected with valve rod, at least one group of seal ring is provided with between the inwall of gland and valve rod, between valve gap and valve seat, valve pocket has been installed with in described connection chamber, the outer circumferential face of valve pocket offers the connection opening impelling medium inlet passage and medium to flow out channel conductive, described spool includes the shrouding be connected with valve rod, axial reciprocating slippage in the connection opening that shrouding is in valve pocket, and shrouding offers pilot hole.
Adopt technique scheme, Sealing between valve body and valve gap is set to the gland can dismantled with valve gap, and be provided with at least one group of seal ring between gland and valve rod, sealing can be kept between seal ring and valve rod, valve rod is in running, and the friction factor between seal ring is little, sensitivity when valve rod is run can not be affected, and ensure that normal unlatching or the closedown of valve body; Valve pocket press-fit between valve seat and valve gap, be not only convenient to install and dismounting, compact structure, and the connection opening that valve pocket is offered can flow out channel conductive for medium inlet passage and medium, flow is large.
The utility model is set to further: it is the Cylindrical object of screw thread rotation that valve pocket includes with valve gap, is provided with the spacing breach with spool adaptation in the connection opening of valve pocket.
Adopt technique scheme, convenient disassembly between valve pocket and valve gap, be convenient to implement to change to seal ring on valve gap; The setting of valve pocket upper limit breach is convenient to implement location to spool, and stable being in connection opening of spool is moved.
The utility model is further set to: one end place that valve rod and diaphragm are connected is provided with the pallet of diaphragm of can conflicting, and the end face that this pallet and diaphragm are conflicted is plane, and the both lateral sides of pallet is provided with arcuation chamfering.
Adopt technique scheme, the plane of pallet can uniformly by diaphragm jack-up, and the setting of arcuation chamfering is then scratched by diaphragm to prevent from pressing through in journey on top.
Below in conjunction with accompanying drawing, the utility model is further described.
