Abstract
The utility model aims at designing a pressure damping connection and disconnection device. By adoption of the pressure damping connection and disconnection device, replacement operation of parts such as a pressure gauge and joints is realized under the state without releasing the pressure of a pipeline. The pressure damping connection and disconnection device is provided with a valve body for connection with the pipeline, wherein a stepped type through hole is manufactured in the valve body, and is internally provided with a pressing block; a vertical blind hole and a horizontal groove are manufactured in the middle of the pressing block and are communicated; a cavity body at the bottom part of the pressing block is internally provided with a compression spring for pushing the pressing block to move up and down in the valve body so as to realize connection or disconnection between the pressing block and a fluid in the cavity body at the bottom part. The pressure damping connection and disconnection device can be promoted and applied in safety protection of the industries of replacement of the parts such as the pressure gauge and the joints under the state without releasing the pressure of the pipeline, the maintenance effect is improved and the economic loss is reduced.
Description
Technical field
Model utility belongs to the pipe jointer part on gas circuit Huo Ye road.
Background technique
Industry now and people's life be unable to do without pressure gauge everywhere, and pressure gauge is for knowing the pipeline of pipeline pressure, and pressure instrument belongs to easy consumption device, changes frequently, is unfavorable for the working state that total system is stable.When pressure gauge is switched on or disconnect, momentary action power was dashed forward once or anticlimax, and instrument sensibility elasticity element is produced to larger ill-effect, affected manometric precision and working life.
In addition; applying gas circuit or liquid line industry very widely; often can run into the situation of maintenance; when running into, need local overhauling or change pressure gauge and during the operation such as some joints, switch, must turn off the main valve of these branch roads, even like this; after pressure gauge and some joints, switch opens dismounting; the gas retaining in pipeline or liquid also can leak out, and particularly some danger, poisonous gas or liquid can pollute air, and the person is damaged.In addition, turn off main valve, wait the pressure release operation of being later correlated with again, long in time limit, energy loss is large.
Summary of the invention
Model utility object is the open close device of a kind of pressure damping of design, realize the replacing operation of the parts such as pressure gauge under not pressure release of pipeline state, joint, and the pressure in the time of making pressure gauge enter working state raises gradually slowly or reduces, and is stabilized within the scope of certain pressure.
The open close device of pressure damping, it has the valve body for being connected with pipeline, is shaped with step type through hole in valve body, and in this through hole, briquetting is housed, and is shaped with vertical blind hole and transverse groove in the middle of this briquetting, and is communicated with between vertical blind hole and transverse groove; Compress Spring is housed in briquetting bottom cavity to be promoted briquetting and in valve body, moves up and down and realize briquetting and the conducting of bottom cavity inner fluid or blocking-up.
Briquetting top is shaped with convex edge and coordinates with step in valve body, and has seal washer between both surface of contact; Under briquetting lower, transverse groove, overlap and have " O " shape seal ring.
Valve body step type through hole bottom cover has sleeve pipe, sleeve pipe to be circumscribed with plug screw for other element is fixed in valve body.
The open close device of model utility pressure damping can be applied to the parts such as pressure gauge under pipeline total system normal working, joint the industries such as replacing safety protection and improve maintenance effect; reduce energy consumption waste and the economic loss of the frequent pressure release of total system, and promote precision and the working life of pressure gauge working state.
Accompanying drawing explanation
Fig. 1 is exactly the plan view of the open close device of pressure damping, and Fig. 2 is Fig. 1 plan view.Wherein part 1 is valve body, and part 2 is briquetting, and part 3 is seal washer, and part 4 is O RunddichtringO, and part 5 is Compress Spring, and part 6 is pipe box, and part 7 is plug screw.
Schematic diagram when Fig. 3 is model utility blocking-up.
Schematic diagram when Fig. 4 is model utility conducting.
Embodiment
As Fig. 1-2 has provided model utility embodiment.The open close device of pressure damping, the valve body 1 that it has for being connected with pipeline, is shaped with step type through hole in valve body 1, and in this through hole, briquetting 2 is housed, and in the middle of this briquetting 2, is shaped with vertical blind hole and transverse groove, and is communicated with between vertical blind hole and transverse groove; Compress Spring 5 is housed in briquetting 2 bottom cavities to be promoted briquettings 2 and in valve body 1, moves up and down and realize briquetting 2 and the conducting of bottom cavity inner fluid or blocking-up.Briquetting 2 tops are shaped with convex edge and coordinate with step in valve body 1, and have seal washer 3 between both surface of contact; Under briquetting 2 lower, transverse grooves, cover has O-ring seals 4.Valve body 1 step type through hole bottom cover has sleeve pipe 6, sleeve pipe 6 to be circumscribed with the plug screw 7 being communicated with sleeve pipe 6.
As Fig. 3-4 have provided model utility working principle schematic diagram.In figure, part 0 is for inventing therewith the objects such as joint that (the open close device of pressure damping) is connected.
The open close device of this pressure damping and joint are threaded connection, as shown in Figure 4, when joint 0 is connected by screw thread precession with the top of the open close device of pressure damping, Compress Spring 5 is the compressed while gradually, special type briquetting 2 moves down, when being depressed into after to a certain degree joint screw thread screws, the medium " connection " that the through hole on special type briquetting 2 and lower space are mobile.
On the contrary, when the internal thread on joint 0 open close device top by pressure damping revolves on gradually, also resilience gradually of compressed spring 5 before, promotes to move on special type briquetting 2, and the medium of bottom is blocked, with leakage-preventing, shown in Fig. 3.
