Abstract
The utility model belongs to the design and technical field of improvement of natural gas line maintenance of equipment, pressure-inducting device is balanced more particularly to a kind of PE pipelines, including control valve, the two folding corrugated flexible metal tubes in left and right are connected by the bump joint of steel respectively in the both sides of control valve, the other end of metal hose also is provided with the bump joint of steel.The utility model is simple and reasonable, controls control valve, switch practicality flexible, easy to operate in production practices at any time.
Description
Technical field
The utility model belongs to the design and technical field of improvement of natural gas line maintenance of equipment, and in particular to a kind of PE pipes
Line balance pressure-inducting device.
Background technology
PE pipeline valve materials are polyethylene, are influenced by pressure, temperature, and especially new line and reserved well company before is complete
Bi Shi, there are upstream and downstream pressure difference stress reasons, open very difficult.It is firmly excessive easily by spool again because material is polyethylene
It breaks disconnected, does a front and back pipeline pressure guiding pipe now, be conducive to, by upstream and downstream pressure balance, light valve opening, spool not caused to hinder
Evil.
Invention content
The purpose of this utility model is that a kind of device being exclusively used in pipeline balance impulse made of PE materials of design, this
Device can greatly reduce production safety hidden danger in production practice, provide production efficiency.
The technical solution of the utility model：A kind of PE pipelines balance pressure-inducting device, including control valve, in control valve
Both sides connect the two folding corrugated flexible metal tubes in left and right, the other end of metal hose by the bump joint of steel respectively
Bump joint equipped with steel.It is equipped with handle hand in the front of control valve and/or the back side.It is equipped with and connects in the lower part of control valve
Connector.Connector has supporting rack.Welding is equipped with engaging lug on bump joint.
Advantageous effect：The utility model is simple and reasonable, controlled at any time in production practices control valve, switch flexibly,
Practicality easy to operate.After flanged joint is good, upstream pressure medium can be equilibrated in downstream line at any time.Reduce life well
Accident potential in safety is produced, while good protection also is played to the use of PE tubing.
Description of the drawings
Attached drawing 1 is the main structure diagram of the utility model.
Specific implementation mode
Embodiment 1, a kind of PE pipelines balance pressure-inducting device, as shown in Figure 1, including control valve 1, in control valve 1
Both sides connect the two folding corrugated flexible metal tubes 2 in left and right, the other end of metal hose by the bump joint of steel respectively
It also is provided with the bump joint 20 of steel.Bump joint can be path changing head.
In practice, if pressure is big, staff needs firmly to help valve, therefore can be in the control valve 1
Front and/or the back side be equipped with handle hand 11, be convenient for helping, be allowed to more stable.
In practice, it is sometimes necessary to found the device and operate on the ground, therefore, in the control valve 1
Lower part is equipped with connector 10, and connector 10 has supporting rack 3 so that it is convenient to operate.
In practice, since corrugated flexible metal tube has certain extensibility, it will appear if there is pressure is excessive in operation
Excessively there is security risk in hose expansion, therefore welding is equipped with engaging lug 21 on the bump joint 20, with one section of rope
Connect two connectors（Engaging lug）, the extension limit of metal hose can be controlled in this way, protect operating personnel.
