Abstract
The utility model provides a connecting pipe for opening a ball valve with double blow off mouths. The connecting pipe comprises a section of polyethylene (PE) pipe, and two ends of the PE pipe are respectively communicated with valves on two sides of the ball valve with the double blow off mouths through fastening pieces. According to the connecting pipe for opening the ball valve with the double blow off mouths, the two ends of the PE pipe are connected with two sides of the ball valve with the double blow off mouths, so that part of natural gas inside the pipe flows through the connecting pipe, and split-flow effect is achieved. Thus pressure difference of the two sides of the ball valve with the double blow off mouths is reduced, an operator can easily open a large diameter valve, and time and energy are saved in operation.
Description
Technical field
The utility model belongs to the gas pipeline engineering field, relates in particular to a kind of two connecting tubes that diffuse ball valve that are used to open.
Background technique
In the existing technology, two ball valves that diffuse are valves commonly used in the gas pipeline, are provided with before and after its ball valve and diffuse valve, and are as shown in Figure 1.At daily gas pipeline in the newly-built or maintenance process, the two valves such as ball valve that diffuse that connect old pipeline are in closed condition.When pipeline construction newly-built or that maintenance is good finish with old pipeline UNICOM after; When replacing ventilation; There is bigger pressure difference in two ball valve front and back of diffusing, and in middle pressure pipeline, upstream pressure often has 0.2-0.4MPa; And do not have pressure behind the valve, make that valve such as de250, de315, the de355 of some big calibers is two to diffuse ball valve and be difficult to open.Operator will open such ball valve, need overcome gas pressure in the high pipe, and constructing operation wastes time and energy.
The model utility content
The utility model has solved the technical problem that there is pressure difference in the ball valve both sides that exist in the gas pipeline engineering process in the existing technology, causes ball valve to be difficult to open.
To this technical problem; The utility model provides a kind of two connecting tubes that diffuse ball valve that are used to open; Its two ends are connected with two both sides of diffusing ball valve respectively, and the interior part rock gas of pipe is flow through from connecting tube, reduce the pressure difference of ball valve both sides; Thereby operator just can open the bassoon diameter ball valve easily, and it is time saving and energy saving to operate.
The technological scheme of the utility model is:
A kind ofly be used to open two connecting tubes that diffuse ball valve, said connecting tube comprises one section PE pipe, and the two ends of said PE pipe all are communicated with two valves that diffuse the ball valve both sides respectively through fastening piece.
As the further improvement of the utility model, said fastening piece is metal threaded union.
The utility model provides is used to open two connecting tubes that diffuse ball valve; Through adopting fastening piece to be connected with two both sides of diffusing ball valve respectively at the two ends of PE pipe; The interior part rock gas of pipe is flow through from connecting tube, reach the effect of shunting, thereby reduce the pressure difference of ball valve both sides; Operator just can open the bassoon diameter ball valve easily, and it is time saving and energy saving to operate.
Description of drawings
Fig. 1 is two structural representations that diffuse ball valve.
Connecting tube and two structural representations that diffuse ball valve that Fig. 2 provides for the utility model.
Wherein, 1---two ball valves that diffuse, 11---first valve, 12---second valve, 2---the PE pipe, 21---first fastening piece, 22---second fastening piece.
Embodiment
Clearer for technical problem, technological scheme and beneficial effect that the utility model is solved, below in conjunction with accompanying drawing and embodiment, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
The utility model provides a kind of two connecting tubes that diffuse ball valve 1 that are used to open.In the utility model, said pair of structure of diffusing ball valve 1 is as shown in Figure 1, and its both sides are respectively equipped with first valve 11 and second valve 12.
The structure of said connecting tube is as shown in Figure 2; Comprise one section PE pipe 2; The two ends of PE pipe 2 are communicated with two valves that diffuse ball valve 1 both sides through fastening piece respectively; An end that is PE pipe 2 is communicated with first valve 11 through first fastening piece 21, and the other end of PE pipe 2 is communicated with second valve 12 through second fastening piece 22.Need to prove that must well can not there be gas leakage at the two ends of PE pipe 2 with two diffusing being connected of ball valve both sides, therefore fastening piece are had higher requirement.Particularly, as the further improvement of the utility model, said fastening piece is metal threaded union, this metal threaded union can guarantee PE manage 2 two ends respectively with first valve 11 and second valve, 12 close-coupled, and avoid PE pipe 2 to be distorted shape.
When there is pressure difference in the ball valve both sides of big caliber; When causing valve to be difficult to open; The connecting tube that can adopt the utility model to provide, the two ends that are specially said PE pipe 2 are communicated with the both sides of ball valve through fastening piece respectively, make to manage in the connecting tube that interior portion gas provides from the utility model to flow through; The pressure of ball valve both sides can be reduced, thereby this ball valve can be easily opened.
To sum up, the utility model provides is used to open two connecting tubes that diffuse ball valve, can make that the part rock gas flows through from connecting tube in the pipe; Reach the effect of shunting; Thereby reduce the pressure difference of ball valve both sides, operator just can open the bassoon diameter ball valve easily, and it is time saving and energy saving to operate.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
