Embodiment
As shown in Figure 1, a kind of pipeline pressure controller, including mechanical valve 10, shell 1, adjusting rod 2 and adapter tube 3, mechanical valve
10 are equipped with mechanical valve plectrum 101, and mechanical valve plectrum 101 is the valve switch of mechanical valve 10.There is pressure chamber inside shell 1,
The pressure chamber top of shell 1 is equipped with spring 5, and the pressure chamber lower part of shell 1 is equipped with bellows 6, is equipped with bellows at the top of bellows 6
Top plate 7,6 bottom of bellows are equipped with bellows mounting base 8, are provided with adjusting rod corresponding with adjusting rod 2 at the top of shell 1 and walk
Hole, the adjusting rod that 2 bottom of adjusting rod passes through 1 top of shell are walked hole and are fixed on bellows top plate 7.It is fixed on adjusting rod 2
The mechanical valve plectrum 101 of sliding block 9 outside shell 1, mechanical valve 10 is corresponding with 9 position of sliding block on adjusting rod 2；
External screw thread is equipped with outside the adjusting rod 2 of the present embodiment, 9 inner sidewall of sliding block is equipped with internal screw thread, sliding block 9 and 2 spiral shell of adjusting rod
The connection of line liftable.1 bottom of shell will take over 3 accesses and need pressure by nut cap 4 and 3 airtight connection of adapter tube when practical practical
On the pipeline of control, the lumen of adapter tube 3 is allowed to be connected with the lumen of pipeline, the flow pressure of pipeline and the flow pressure of adapter tube 3
It is equal.Central through hole, the lumen of adapter tube 3, the central through hole of bellows mounting base 8, wave are provided in the middle part of bellows mounting base 8
6 inner cavity of line pipe is sequentially communicated.
As shown in Figure 1, being equipped with seal ring set between 1 outer wall of nut cap 4 and shell.3 top bump of adapter tube is equipped with stage portion, lid
4 section of cap is in " L " word shape, and nut cap 4 is made of vertical annular sleeve and transverse annular set, and the vertical annular sleeve of nut cap 4 is closely wrapped
It is wrapped on 1 outer wall of shell, the transverse annular set of nut cap 4 is closely wrapped in 3 top outer wall of adapter tube, the transverse annular set of nut cap 4
The stage portion downside of medial surface and adapter tube 3 is in close contact.
As shown in Figure 1, bellows 6 lies against 8 top of bellows mounting base, bellows mounting base 8 and 1 bottom of shell
Clamping.It is fixedly connected at the top of 7 bottom of bellows top plate and bellows 6,7 top of bellows top plate is fixedly connected with 5 bottom of spring.
The working principle of the utility model is as follows：
In use, will take on the pipeline that 3 accesses need pressure to control, the lumen of adapter tube 3 is allowed to be connected with the lumen of pipeline
Logical, the flow pressure of pipeline is equal with the flow pressure of adapter tube 3, and mechanical valve 10 is installed at the flow inlet port of pipeline, when
When the lumen pressure of pipeline pressure monitoring control devices to adapter tube 3 is excessive, the sliding block 9 on adjusting rod 2 touches mechanical valve plectrum
101, mechanical valve plectrum 101 controls mechanical valve 10 and closes, and the flow inlet port of such pipeline will be closed, the flow in pipeline
Source is cut off, and the flowexit of pipeline will continue to output flow, and the flow pressure of such pipeline will reduce, and work as pipeline pressure
When the lumen pressure of monitoring control devices to adapter tube 3 becomes smaller, the sliding block 9 on adjusting rod 2 would not touch mechanical valve plectrum 101,
Mechanical valve plectrum 101 controls mechanical valve 10 and opens, and the flow inlet port of pipeline will be opened.The mechanical valve 10 of the utility model
For machinery valve open in usual, as shown in Figure 1, pipeline flow pressure under normal circumstances, adjust the position of sliding block 9 so that
Sliding block 9 is in the working condition for not touching mechanical valve plectrum 101, the flow in the flow pressure increase in pipeline, adapter tube 3
Pressure similarly increases, and the flow pressure in adapter tube 3 pushes bellows 6 to move upwards, and bellows 6 pushes bellows top plate 7, adjusts
Pole 2 overcomes the elastic force of spring 5 to move upwards, and spring 5 will be compressed at this time, when the flow pressure in adapter tube 3 reaches maximum
When preset value, the sliding block 9 on adjusting rod 2 touches mechanical valve plectrum 101, and mechanical valve plectrum 101 controls mechanical valve 10 and closes, this
The flow inlet port of sample pipeline will be closed, the traffic source in pipeline be cut off, and the flowexit of pipeline will continue to it is defeated
The flow pressure of outflow, such pipeline will reduce.When the lumen pressure of adapter tube 3 becomes smaller, adjusting rod 2 will be in spring 5
Elastic force act on lower descending motion, spring 5 extends, and bellows 6 compresses, and bellows top plate 7, adjusting rod 2 move downward, and works as adapter tube
When pressure medium reaches minimum preset value in 3, the top shoe 11 on adjusting rod 2 touches mechanical valve plectrum 101, and mechanical valve is opened,
The medium entrance of the valve actuator counteragent that mechanical valve is controlled, valve opening, such pipeline is opened, and medium comes in pipeline
Source is connected, and the amount that medium is entered in pipeline is greater than output quantity, and the pressure medium of such pipeline increases.So circulation, makes in pipeline
Pressure medium floats in the range of remaining at setting.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
