Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As shown in Figure 1, a kind of non-filling structure self-contained pressure regulator, including valve body 1, valve seat 2, spool 4, valve rod
10, valve deck 6 and executing agency 9.
The left and right sides of valve body 1 opens up left influent stream channel 100 and right influent stream channel 101 respectively, and the channel Zuo Jinliu 100 is located at
The upper end in right influent stream channel 101 is equipped with the intermediate influent stream for being connected to the two between the channel Zuo Jinliu 100 and right influent stream channel 101
Mouthful, valve seat 2 is fixedly connected on intermediate flow inlet, and valve seat 2, which opens up, adjusts flow inlet 200.
Valve seat 2 is fixedly connected on intermediate flow inlet, and valve seat 2, which opens up, adjusts flow inlet 200, and valve deck 6 is fixedly connected on valve
1 upper end of body, valve rod 10 are plugged in valve deck 6, and sealing ring 8 is arranged between the upper end and valve rod 10 of valve deck 6, and spool 4 is arranged in valve
The lower end of bar 10, spool 4 is corresponding with flow inlet 200 is adjusted, and the upper end of valve rod 10 exceeds valve deck 6, and the upper end of valve rod 10 is arranged bullet
Spring base groove 1100 is arranged in spring abutment 11, the outer rim of spring base 11, and the top of valve rod 10 is arranged executing agency 9, is arranged outside valve deck 6
Pressure adjustment disk 5, is arranged two springs 7 between spring base 11 and pressure adjustment disk 5, spring 7 is set in valve deck 6 and valve rod simultaneously
Outside 10, one of spring 7 is connect with spring base groove 1100.The lower end setting connecting plate 12 of executing agency 9,12 sets of connecting plate
It is located at outside valve rod 10, column 13 is fixedly connected between connecting plate 12 and valve deck 6.
In the present invention, sealing ring 8 is high-performance sealed O-ring, is existing conventional structure.
In the present invention, executing agency 9 is diaphragm actuator, is existing conventional structure.
In the present invention, metallic gasket 3 is set between intermediate flow inlet and valve seat 2.
When medium flows through valve body 1, the free area between the position of spool 4, i.e. spool 4 and valve seat 2 determines medium flow field
Amount, controlled downstream pressure are transmitted to executing agency's 9(working masks) on, and it is converted into detent force herein.It is pre-tightened according to spring 7
Power size, detent force adjust 4 position of spool.The size of 7 pretightning force of spring is adjusted by pressure adjustment disk 6.Work as downstream pressure
When greater than set point adjusted, compressed spring 7, with movable valve plug 4, valve is closed in proportion according to pressure variety.After valve
Pressure drop is on earth in set point, then the reaction force as caused by spring 7, band movable valve plug 4 make valve opening degree according to pressure
Change amount scales up, to reach decompression, pressure stabilizing purpose.
