Summary of the invention
In order to solve the problems referred to above that prior art exists, this utility model provides the vacuum of a kind of adjustable sealing specific pressure Pipeline expansion device, simple in construction, reduces cost and is prone to penetration and promotion, solves vacuum pressure pipeline junction seal pressure Nonadjustable defect, overcome rigid conduit connect between the telescoping problem that produces due to thermal stress, it is ensured that system steady Qualitative, reduce the probability of environmental pollution, improve device stable operation cycle.
The technical scheme that this utility model is used is: the vacuum pipe retractor device of a kind of adjustable sealing specific pressure, including Prime connector, rear class connector, sealing device, stuffing-box and locking device, described sealing device respectively with described front cascade Fitting and described rear class connector connect, and are provided with described stuffing-box, institute between described prime connector and described sealing device Stating and be provided with described stuffing-box between rear class connector and described sealing device, described locking device is arranged on described stuffing-box On.
Further, described stuffing-box all includes filler and for the gland compressed by described filler, described sealing Being provided with the groove accommodating described filler on device, described gland compresses with described filler and is connected.
Further, described groove is arranged on the end of described sealing device.
Further, described locking device includes that adjusting screw rod, described adjusting screw rod are located in two described glands On, described filler is locked by described adjusting screw rod with described sealing device.
Further, described filler uses establishment packing filling, machine-shaping filler or docking molding filler.
Further, described stuffing-box is arranged on one end of described sealing device, and described locking device one end is located in institute Stating on stuffing-box, the other end of described locking device is arranged on described prime connector.
The beneficial effects of the utility model are:
1, this utility model uses adjusting screw rod and adjusting nut can adjust thrust in real time, overcomes between rigid conduit The telescoping problem caused because of thermal stress.
2, this utility model is by applying different coupling mechanism forces to gland, remains filler and sealing device pressure Tightly, thus ensure the seal pressure in vacuum pipe connection, and seal pressure is adjustable, keeps the vacuum in pipeline, it is ensured that be raw Produce stability during plant running, reduce and open stop frequency, energy-saving and cost-reducing, decrease the probability of environmental pollution simultaneously, improve dress Put stable operation cycle.
3, this utility model has simple in construction, reduces cost, it is easy to the feature of penetration and promotion.
