Abstract
The utility model relates to gas pipeline conveying equipment technical field, especially a kind of rock gas cutting type pressure governor.This rock gas cutting type pressure governor, comprise the valve body be arranged on gas pipeline, valve body one end is connected with pressure governor, and the valve body the other end is provided with cut-off valve.The utility model structure is simple, has that volume is little, lightweight, reliable performance, an advantage such as easy for installation.When pressure governor occurs that contingency makes outlet pressure exceed the safety cut-off pressure of setting, pressure under cut-off valve film promotes cut-off valve brake rod, makes cut-out valve rod throttle down cut off source of the gas under the action of the spring, reaches the object of safety protection.
Description
Technical field
The utility model relates to gas pipeline conveying equipment technical field, especially a kind ofly need automatically control outlet pressure rock gas cutting type pressure governor with the change of operating mode along with rock gas.
Background technique
Pressure governor refers in gas conveying system and claims for pressure controlled equipment.Pressure governor is that higher inlet pressure is adjusted to lower outlet pressure, and need automatically control outlet pressure in a certain setting value with the change of operating mode along with rock gas.Traditional pressure governor complex structure, air-flow directly impacts on film, and film is fragile, and working life is short, have impact on voltage regulation result.
Model utility content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provides a kind of structure simple, the natural gas user pressure governor that voltage regulation result is good.
The utility model solves the technological scheme that its technical problem adopts: a kind of rock gas cutting type pressure governor, comprise the valve body be arranged on gas pipeline, valve body one end is connected with pressure governor, the valve body the other end is provided with cut-off valve, described pressure governor comprises pressure governor housing, pressure governor casing center is built-in with pressure governor pallet, pressure governor spring is provided with above pressure governor pallet, pressure governor pallet is provided with pressure governor film, pressure governor pallet lower surface is provided with connecting rod, connecting rod is fixedly connected with pressure governor drive link, pressure governor drive link is connected with pressure governor valve rod, pressure governor valve stem tip is provided with pressure governor valve plate, described cut-off valve comprises and is arranged on cut-off valve housing on valve body and shut-off valve body, cut-off valve housing is built-in with cut-off valve spring, cut-off valve spring is fixedly connected with cut-off valve pallet, cut-off valve pallet is provided with cut-off valve film, cut-off valve pallet is fixedly connected with cut-off valve brake rod, cut-off valve brake rod is connected with cut-out valve rod, cuts off valve stem tip and is provided with cut-out valve plate.
Further, described pressure governor spring one end is fixedly connected with pressure governor pallet, and the pressure governor spring the other end is fixed on pressure governor housing by positioning pressuring plate.
Further, pinned connection is passed through between described pressure governor drive link and pressure governor valve rod.
Further, described pressure governor valve plate and cut-out valve plate are all built in valve cavity.
Further, described gas pipeline offer with pressure governor valve plate and cut off the corresponding opening of valve plate.
The beneficial effects of the utility model are: the utility model structure is simple, have that volume is little, lightweight, reliable performance, an advantage such as easy for installation.When pressure governor occurs that contingency makes outlet pressure exceed the safety cut-off pressure of setting, pressure under cut-off valve film promotes cut-off valve brake rod, makes cut-out valve rod throttle down cut off source of the gas under the action of the spring, reaches the object of safety protection.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. pressure governor housings, 2. pressure governor spring, 3. pressure governor film in figure, 4. pressure governor pallet, 5. pressure governor drive link, 6. pressure governor valve rod, 7. pressure governor valve plate, 8. gas pipeline, 9. valve body, 10. cut-off valve film, 11. cut-off valve springs, 12. cut-off valve pallets, 13. cut-off valve housings, 14. shut-off valve bodies, 15. cut-off valve brake rods, 16. cut off valve rod, and 17. cut off valve plate.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
Rock gas cutting type pressure governor as shown in Figure 1, comprise the valve body 9 be arranged on gas pipeline 8, valve body 9 one end is connected with pressure governor, valve body 9 the other end is provided with cut-off valve, pressure governor comprises pressure governor housing 1, pressure governor housing 1 center is built-in with pressure governor pallet 4, pressure governor spring 2 is provided with above pressure governor pallet 4, pressure governor pallet 4 is provided with pressure governor film 3, pressure governor pallet 4 lower surface is provided with connecting rod, connecting rod is fixedly connected with pressure governor drive link 5, pressure governor drive link 5 is connected with pressure governor valve rod 6, pressure governor valve rod 6 top is provided with pressure governor valve plate 7, cut-off valve comprises and is arranged on cut-off valve housing 13 on valve body 9 and shut-off valve body 14, cut-off valve housing 13 is built-in with cut-off valve spring 11, cut-off valve spring 11 is fixedly connected with cut-off valve pallet 12, cut-off valve pallet 12 is provided with cut-off valve film 10, cut-off valve pallet 12 is fixedly connected with cut-off valve brake rod 15, cut-off valve brake rod 15 is connected with and cuts off valve rod 16, cuts off valve rod 16 top and is provided with cut-out valve plate 17.
Pressure governor spring 2 one end is fixedly connected with pressure governor pallet 4, and pressure governor spring 2 the other end is fixed on pressure governor housing 1 by positioning pressuring plate; Pinned connection is passed through between pressure governor drive link 5 and pressure governor valve rod 6; Pressure governor valve plate 7 and cut-out valve plate 17 are all built in valve body 9 cavity; Gas pipeline 8 offer with pressure governor valve plate 7 and cut off the corresponding opening of valve plate 17.
