Abstract
The invention aims to design a pressure damping on-off device. The replacement operation of a pressure meter, a connector and other parts of a pipeline in a pressure-relief-free state is achieved. The pressure damping on-off valve is provided with a valve body used for being connected with the pipeline, a stepped through hole is formed in the valve body, a pressing block is arranged in the through hole, a vertical blind hole and a transverse groove are formed in the middle of the pressing block, and the vertical blind hole and the transverse groove are communicated. A compression spring is arranged in a cavity in the bottom of the pressing block to push the pressing block to vertically move inside the valve body, and then the pressing block is communicated or cuts off from fluids inside the cavity in the bottom of the pressing block. The pressure damping on-off device can be widely applied to safety protection for the replacement operation of the pressure meter, the connector and other parts of the pipeline in the pressure-relief-free state, the maintaining effect is improved, and economic losses are reduced.
Description
Technical field
The invention belongs to the pipe jointer spare on gas circuit or liquid road.
Background technique
Now industry and people's life be unable to do without pressure gauge everywhere, and pressure gauge is used 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 was switched on or disconnect, momentary action power was dashed forward once or anticlimax, and instrument sensibility elasticity element is produced larger ill-effect, affected manometric precision and working life.
In addition; using very widely gas circuit or liquid line industry; often can run into the situation of maintenance; 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 when running into; after pressure gauge and some joints, switch opens dismounting; the gas that retains in the 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 correlated with again later on, long in time limit, energy loss is large.
Summary of the invention
The present invention seeks to design the open close device of a kind of pressure damping, the replacing operation of the parts such as the pressure gauge under not pressure release of the realization pipeline state, joint, and the pressure in the time of making pressure gauge enter working state raises gradually slowly or reduces, and is stabilized in the certain pressure scope.
The open close device of pressure damping, it has the valve body that is connected for pipeline, is shaped with the step type through hole in the 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 the transverse groove; Compress Spring promotion briquetting is housed in the briquetting bottom cavity in valve body, moves up and down realization briquetting and the conducting of bottom cavity inner fluid or blocking-up.
Briquetting top is shaped with the convex edge and cooperates with step in the valve body, and between both surface of contact seal washer is arranged; Overlap under the briquetting lower, transverse groove " O " shape seal ring is arranged.
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 the valve body.
The open close device of pressure damping of the present invention can be applied to the parts such as the pressure gauge, joint under the pipeline total system normal working the industries such as replacing safety protection and improve the 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.
Description of drawings
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 the 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 representation when blocking.
Schematic representation when Fig. 4 is conducting of the present invention.
Embodiment
Provided the specific embodiment of the invention such as Fig. 1-2.The open close device of pressure damping, it has for the valve body 1 that is connected with pipeline, is shaped with the step type through hole in the valve body 1, and in this through hole briquetting 2 is housed, and is shaped with vertical blind hole and transverse groove in the middle of this briquetting 2, and is communicated with between vertical blind hole and the transverse groove; Compress Spring 5 promotion briquettings 2 are housed in briquetting 2 bottom cavities in valve body 1, move up and down realization briquetting 2 and the conducting of bottom cavity inner fluid or blocking-up.Briquetting 2 tops are shaped with the convex edge and cooperate with step in the valve body 1, and between both surface of contact seal washer 3 are arranged; Cover has O-ring seals 4 under the briquetting 2 lower, transverse grooves.Valve body 1 step type through hole bottom cover has sleeve pipe 6, sleeve pipe 6 to be circumscribed with the plug screw 7 that is communicated with sleeve pipe 6.
Provided working principle schematic representation of the present invention such as Fig. 3-4.Part 0 is for inventing therewith the objects such as joint that (the open close device of pressure damping) is connected among the figure.
The open close device of this pressure damping and joint are threaded connection, as shown in Figure 4, when joint 0 is connected by the 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 the special type briquetting 2 and lower space flow.
On the contrary, when the internal thread on joint 0 open close device top by pressure damping revolved on gradually, before also gradually resilience of compressed spring 5 promoted to move on the special type briquetting 2, and the medium of bottom is blocked, and is with leakage-preventing, shown in Figure 3.
