Abstract
The present invention seeks to design the open close device of a kind of pressure damping, realize the replacing operation of the parts such as pressure gauge, joint under pipeline not pressure release state.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, and is vertically communicated with between blind hole and transverse groove in the middle of this briquetting; Briquetting bottom cavity promotes briquetting built with Compress Spring and moves up and down in valve body and realize briquetting and the conducting of bottom cavity inner fluid or blocking-up.The open close device of pressure damping of the present invention can be applied to the safety protection of the industries such as the replacing of the parts such as pressure gauge, joint under pipeline not pressure release state and improve maintenance effect, reduces economic loss.<!--1-->
Description
Technical field
The invention belongs to the pipe jointer part of gas circuit or fluid path.
Background technique
The life of present industry and people be unable to do without pressure gauge everywhere, and pressure gauge is for needing the pipeline knowing pipeline pressure, and pressure instrument belongs to and easily consumes device, changes frequent, is unfavorable for the working state that total system is stable.When pressure gauge is switched on or disconnect, instantaneous force was dashed forward once or anticlimax, produces larger ill-effect, affect manometric precision and working life to instrument sensibility elasticity element.
In addition; in the gas circuit applied widely or liquid line industry; often can run into the situation of maintenance; when run into need local overhauling or change pressure gauge and some operations such as joint, switch time, the main valve of these branch roads must be turned off, even if like this; after pressure gauge and some joints, switch opens dismounting; the gas retained in pipeline or liquid also can leak out, and particularly some danger, poisonous gas or liquid can pollute air, damage the person.In addition, turn off main valve, wait pressure release to carry out relevant operation again, long in time limit, energy loss is large later.
Summary of the invention
The present invention seeks to design the open close device of a kind of pressure damping, realize the replacing operation of the parts such as pressure gauge, joint under pipeline not pressure release state, and pressure when pressure gauge can be made to 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, and is vertically communicated with between blind hole and transverse groove in the middle of this briquetting; Briquetting bottom cavity promotes briquetting built with Compress Spring and moves up and down in valve body 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; " O " shape seal ring of having trapped of briquetting lower, transverse groove.
Valve body step type through hole bottom cover has sleeve pipe, and sleeve pipe is circumscribed with plug screw for being fixed in valve body by other element.
The open close device of pressure damping of the present invention can be applied to the safety protection of the industries such as the replacing of the parts such as pressure gauge, joint under pipeline total system normal working 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.
Fig. 3 is the present invention's schematic diagram when blocking.
Schematic diagram when Fig. 4 is conducting of the present invention.
Embodiment
As Fig. 1-2 gives the specific embodiment of the invention.The open close device of pressure damping, it has the valve body 1 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 is shaped with vertical blind hole and transverse groove, and is vertically communicated with between blind hole and transverse groove in the middle of this briquetting 2; Briquetting 2 bottom cavity promotes briquetting 2 built with Compress Spring 5 and moves up and down in valve body 1 and realize briquetting 2 and the conducting of bottom cavity inner fluid or blocking-up.Briquetting 2 top is shaped with convex edge and coordinates with step in valve body 1, and has seal washer 3 between both surface of contact; The O-ring seals 4 of having trapped of briquetting 2 lower, transverse groove.Valve body 1 step type through hole bottom cover has sleeve pipe 6, and sleeve pipe 6 is circumscribed with the plug screw 7 be communicated with sleeve pipe 6.
As Fig. 3-4 gives working principle schematic diagram of the present invention.In figure, part 0 is invent the objects such as (the open close device of pressure damping) joint of being connected therewith.
The open close device of this pressure damping and joint are threaded connection, as shown in Figure 4, when the top of the open close device of joint 0 and pressure damping is connected by screw thread precession, while Compress Spring 5 is compressed 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 flow.
On the contrary, when joint 0 by the internal thread on the open close device top of pressure damping gradually on revolve time, before by the spring 5 also resilience gradually compressed, promote special type briquetting 2 moves, the medium of bottom is blocked, with leakage-preventing, shown in Fig. 3.
