Abstract
The utility model discloses a high pressure gas pipeline direct -burried valve pit, including the valve pit body, valve pit body upper portion is equipped with the cage, cage and well lid cooperation, and the cage lower part is connected with the pit shaft, pit shaft lower part and the cooperation of well seat, the internal portion of valve pit is equipped with all -welded direct -burried ball valve, all -welded direct -burried ball valve is linked together with the gas pipeline, all -welded direct -burried ball valve is connected with the valve rod, the valve rod both sides all are equipped with the exhaust stack. The utility model discloses a high pressure gas pipeline valve gate adopts the two all -welded direct -burried ball valves that diffuse in area, can not produce any leakage in mark pressure and temperature range, can directly bury in the underground, only need to set up small -size shallow well on ground, the well body structure adopts the mode of prefabricated well seat and pit shaft equipment, saves operating expenses and engineering time greatly, the well body is built in gas pipeline top, and valve valve rod and exhaust stack expose more than the sand face, is difficult for forming airtight space in the well, and the valve operating of being convenient for ties up the procuratorial organ just, and safety ring protects.
Description
Technical field
The utility model relates to a kind of high-pressure gas pipeline direct-burried valve pit.
Background technology
Valve well is that the valve of underground utilities and underground pipeline (as tap water, oil, natural gas line etc.) is in order to facilitate when carrying out the operation of opening and closing part pipe network or upkeep operation at needs, a hole (or well) of similar cubicle is just set, by mounting arrangements such as valves in this hole, be convenient to make regular check on, clean and dredging pipeline, prevent the hinge of line clogging.Valve well is just in this hole.
Direct-buried ball valve is used for the conveying of pipeline medium, due to environment factor caused by, the external surface of ball valve is easily polluted and is corroded, cause its external surface damaged, although direct-buried ball valve has the technology of anticorrosive property at present, but its antiseptic effect is not very remarkable, therefore, in use directly affects the application life of product.
Utility model content
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, a kind of high-pressure gas pipeline direct-burried valve pit is provided, this valve pit inner high voltage valve of gas pipeline adopts two full welding direct-burried ball valve diffused, do not have the phenomenons such as External leakage, and do not need to build high large-scale valve well, only need arrange small-sized shallow well, well body structure adopts the mode of prefabricated pit shaft and the assembling of well seat, greatly saves operating expenses and engineering time.
For achieving the above object, the utility model adopts following technical proposals:
High-pressure gas pipeline direct-burried valve pit, comprises valve pit body, and described valve pit body top is provided with cage, and cage coordinates with well lid, and cage bottom is connected with pit shaft, and lower wellbore coordinates with well seat; Described valve pit body inside is provided with full welding direct-burried ball valve, and described full welding direct-burried ball valve is connected with gas pipeline, and described full welding direct-burried ball valve is connected with valve rod, and described valve rod both sides are equipped with exhaust stack.
Described valve rod is provided with pipe holder, and described pipe holder is connected with exhaust stack.
Described exhaust stack top is provided with vent valve.
Back-up sand between described valve pit body inside and gas pipeline.
In described valve pit body, gas pipeline bottom and full welding direct-burried ball valve bottom are lined with sandbag, and described sandbag bottom is provided with concrete bed course.
The beneficial effects of the utility model are:
High-pressure gas pipeline valve of the present utility model adopts the two full welding direct-burried ball valve diffused of band, adaptable to the change of pressure and temperature, can not produce any leakage within the scope of mark pressure and temperature; Directly can be embedded in underground, need not build high large-scale valve well, only need arrange small-sized shallow well on ground, well body structure adopts the mode of prefabricated pit shaft and the assembling of well seat, greatly saves operating expenses and engineering time; Valve body spherula machining accuracy is accurate, operates light, without bad interference; The well body of high-pressure gas pipeline direct-burried valve pit of the present utility model is arranged on above gas pipeline, back-up sand in valve pit, valve body lower portion pad sandbag and concrete bed course, valve rod and exhaust stack expose more than sand face, not easily form confined space in well, are convenient to valve operation, tie up procuratorial organ just, safety and environmental protection.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model high-pressure gas pipeline direct-burried valve pit;
Fig. 2 be in Fig. 1 A-A to sectional view;
In figure, 1 is full welding direct-burried ball valve, and 2 is exhaust stack, and 3 is valve rod, and 4 is gas pipeline, and 5 is pipe holder, and 6 is well lid, and 7 is cage, and 8 is pit shaft, and 9 is well seat, and 10 is back-up sand, and 11 is sandbag, and 12 is concrete bed course.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As Figure 1-Figure 2, high-pressure gas pipeline direct-burried valve pit, comprises valve pit body, and valve pit body divides four parts such as well lid 6, cage 7, pit shaft 8, well seat 9, and wherein pit shaft and well seat adopt preformed patterns.Valve pit body top is provided with cage 7, and cage 7 coordinates with well lid 6, and middle part cage 6 coordinates with pit shaft 8, and bottom pit shaft 8 coordinates with well seat 9; Valve pit inside is provided with full welding direct-burried ball valve 1, and full welding direct-burried ball valve 1 is connected with gas pipeline 4, and full welding direct-burried ball valve 1 is connected with valve rod 3, and valve rod 3 both sides are equipped with exhaust stack 2.Valve rod 3 is provided with pipe holder 5, and described pipe holder 5 is connected with exhaust stack 2.Exhaust stack 2 top is provided with vent valve.
High-pressure gas pipeline valve adopts the two full welding direct-burried ball valve diffused of band, and prefabricated well body is arranged on above gas pipeline, back-up sand 10 in valve pit, valve body lower portion pad sandbag 11 and concrete bed course 12.
