Abstract

The utility model relates to a pipeline pressure indicating valve. The pipeline pressure indicating valve mainly comprises a valve body, a piston, a spring, a valve rod, a pipe joint and a transparent housing, wherein the valve rod, the piston and the spring are arranged in a valve cavity of the valve body, the upper end of the valve body is connected with the pipe joint through threads, the valve cavity of the valve body is sealed through the pipe joint, the piston is arranged at one end of the valve rod, the valve rod is sleeved with the spring, the spring is arranged between the pipe joint and the piston, the other end of the valve rod extends out of the valve cavity, an indicating header is arranged at the end of the valve rod, the transparent housing is arranged on the outer side of the valve rod in a covering mode, and visible scale marks are arranged on the transparent housing. Pipeline media can directly enter the bottom of the piston through an inlet, the piston overcomes spring force of the spring to move upwards under the action of the pressure of the pipeline media, and the pressure value at the moment is read according to the position where the indicating header is located; after a pipeline is decompressed, the piston moves downwards under the action of the pressure of the spring, and drives the indicating header to move downwards to the position without the pressure scale marks, repair, maintenance and inspection can be carried out on the pipeline, and safety is ensured. The pipeline pressure indicating valve has the advantages of being simple in structure, convenient to use, low in manufacturing cost, not prone to damage and long in service life.

Description

A kind of pipeline pressure indicating valve

Technical field

The utility model relates to a kind of for the annex on petroleum pipeline, particularly a kind of pipeline pressure indicating valve.

Background technique

At present, on oil pipeline, the pipeline pressure display device that it is traditional, is to adopt pressure gauge mostly.Due to the particularity of petroleum pipeline, pressure gauge is arranged on field pipeline, very easily by artificial damage, or is stolen, thereby causes various potential safety hazards.So in oil pipeline, various device and device are guaranteeing under the prerequisite of technical performance, very high to the requirement of its steadiness and theftproof performance.

Summary of the invention

The technical problems to be solved in the utility model is, overcomes the deficiencies in the prior art, and a kind of pipeline pressure indicating valve is provided.

Technical solution of the present utility model is, comprises valve body 1, piston 2, and spring 3, valve rod 4, pipe joint 6 and transparent casing 8, valve rod 4, piston 2 and spring 3 are located in the valve pocket of valve body 1; There is pipe joint 6 upper end of valve body 1 by scyewed joint, and the valve pocket of valve body 1 is sealed; Piston 2 is located at an end of valve rod 4, and the two is as a whole; Spring 3 is placed on valve rod 4, and is placed between pipe joint 6 and piston 2; The other end of valve rod 4 stretches out outside valve pocket, and its end is provided with indication header 9, and the outside of indicating arm head 9 is covered with transparent casing 8, and transparent casing 8 is provided with visual graduation line.

The outside of pipe joint 6 connects with valve body 1 by screw thread; The inner side of pipe joint 6 is provided with through-core hole, and the other end of valve rod 4 stretches out outside valve pocket through the through-core hole on pipe joint 6.

On piston 2 and valve rod 4, be respectively equipped with seal ring 5,12.

Transparent casing 8 is open flume type photopic vision cover, is directly stuck on pipe joint 6.

The valve body 1 that is positioned at piston 2 bottoms is provided with medium import.

Between pipe joint 6 and valve body 1, be provided with sealing gasket 7.

The utility model and prior art the possessed advantage that compares is that simple in structure, easy to use, low cost of manufacture, is convenient to check, not fragile, long service life.

Accompanying drawing explanation

Accompanying drawing is structural representation of the present utility model.

Number in the figure: 1-valve body, 2-piston, 3-spring, 4-valve rod, 5-seal ring, 6-pipe joint, 7-sealing gasket, 8-transparent casing, 9-indicates header, 10-high scale line (maximum pressure graduation line), graduation line under 11-(without pressure graduation line), 12 seal rings.

Embodiment

The utility model relates to a kind of pipeline pressure indicating valve, mainly by valve body 1, and piston 2, spring 3, valve rod 4, pipe joint 6 and transparent casing 8 form, and valve rod 4, piston 2 and spring 3 are located in the valve pocket of valve body 1; There is pipe joint 6 upper end of valve body 1 by scyewed joint, and the valve pocket of valve body 1 is sealed.

Piston 2 is located at an end of valve rod 4, and the two is as a whole; Spring 3 is placed on valve rod 4, and is placed between pipe joint 6 and piston 2; The other end of valve rod 4 stretches out outside valve pocket, and its end is provided with indication header 9, and the outside of indication header 9 is covered with transparent casing 8, and transparent casing 8 is provided with visual graduation line.Its high scale line 10 is pipeline maximum pressure graduation line, and lower graduation line 11 is that pipeline is without pressure graduation line.

The outside of pipe joint 6 connects with valve body 1 by screw thread; The inner side of pipe joint 6 is provided with through-core hole, and the other end of valve rod 4 stretches out outside valve pocket through the through-core hole on pipe joint 6.

The valve body 1 that is positioned at piston 2 bottoms is provided with medium import.

For guaranteeing reliable sealing in valve pocket, on piston 2 and valve rod 4, be respectively equipped with seal ring 5,12, between pipe joint 6 and valve body 1, be provided with sealing gasket 7.

Transparent casing 8 is open flume type photopic vision cover, can directly be stuck on pipe joint 6.By transparent casing 8, can directly read the pressure medium in pipeline.

When use, the medium in petroleum pipeline, the direct bottom that enters into piston 2 from import, under the effect of pressure medium, it is up that piston 2 overcomes the spring force of spring 3, by the indication residing position of header 9, on the scale of transparent casing 8, read pressure value now.

When after pipeline pressure pressure release, piston 2 is descending under the effect of spring pressure, until indication header 9 goes downwards to without pressure graduation line, illustrates that now pipeline is completely in pressure vanishing state, and explanation can keep in repair, maintains, check, guarantee safety.
