Abstract
The utility model discloses a top pressure device with flexible connection, which comprises a main passage air pipe and a branch passage air pipe which connect a pressure-reducing valve set with an air pressure tank, and is characterized in that: a metal soft joint is arranged in the branch passage air pipe. The top pressure device with flexible connection has the advantages that: 1. the air passage pipelines of two branch passages have relative flexibility; 2. the connecting part between the top pressure device and the pressure-reducing valve set is ensured to be sealed tightly; and 3. the difficulties of equipment assembly, installation and maintenance are reduced.
Description
Technical field
The utility model relates to the emergent fire fighting water work field of gas roof pressure, is specifically related to a kind of jack unit that flexibly connects that has.
Background technology
In the emergent fire fighting water work of gas roof pressure, because the gas flow demand is bigger, the Compressed Gas that discharges from the gas cylinder group need divide two parallel branch pressure-reducing valve groups to be pooled to the jack unit part, and two gas path pipes of jack unit part and pressure-reducing valve group two gas path pipes partly are with flange downlink connection (as seeing Fig. 1).Main road tracheae 1, the first branch road tracheae 2 and the second branch road tracheae 3 in the jack unit all are to use welding assembly, and main road tracheae 1 all is threaded with valve on the second branch road tracheae 3; Pressure-reducing valve group part all is threaded togather.Therefore jack unit part and pressure-reducing valve group part all are rigidly connected, and do not have flexibility.The pipeline of jack unit part is after the welding cooling, the relative position of first steel pipe 1 and the 3rd steel pipe 3 can change, can not coincide simultaneously so two flange face sealing surfaces usually occur, cause and intactly to seal in jack unit part and two junctions of pressure-reducing valve group part.Very big difficulty that this structure has been given the assembling of equipment and mounting strap.
Summary of the invention
The utility model provides a kind of jack unit that flexibly connects that has, and the flange sealing surface that solves jack unit part and pressure-reducing valve group part two bypass line junctions coincide simultaneously, guarantees good seal, reduces assembling, installation and the maintenance difficulty of equipment.
In order to realize this purpose, scheme of the present utility model is as follows: a kind of have a jack unit that flexibly connects, and this jack unit comprises main road tracheae and the branch road tracheae that connects pressure-reducing valve group and air pressure tank, it is characterized in that being provided with in the branch road tracheae metal connecting hose.According to an embodiment of the present utility model, the main road tracheae is serially connected with and starts ball valve and maintenance ball valve, the branch road tracheae comprises the first branch road tracheae and the second branch road tracheae, the first branch road tracheae is serially connected with safety valve and maintenance ball valve, the metal connecting hose is located between safety valve and the maintenance ball valve, the main road tracheae also is connected with electro connecting pressure gauge by the second branch road tracheae, also is provided with the metal connecting hose in the second branch road tracheae.
Advantage of the present utility model is: 1, two branch road gas path pipes of jack unit part have flexibility relatively; 2, jack unit and pressure-reducing valve group junction good seal have been guaranteed; 3, equipment assembling, installation and maintenance difficulty have been reduced.

The specific embodiment
As Fig. 2, a kind of have a jack unit that flexibly connects, and this jack unit comprises main road tracheae 1 and the branch road tracheae that connects pressure-reducing valve group 5 and air pressure tank, it is characterized in that being provided with in the branch road tracheae metal connecting hose 6,7.According to an embodiment of the present utility model, main road tracheae 1 all is connected with air pressure tank by pipeline 4 with the branch road tracheae.Main road tracheae 1 is threaded with pressure-reducing valve group 5, be serially connected with in the main road tracheae and start ball valve and maintenance ball valve, the branch road tracheae comprises the first branch road tracheae 2 and the second branch road tracheae 3, the first branch road tracheae 2 is threaded with pressure-reducing valve group 5, be serially connected with safety valve and maintenance ball valve in the first branch road tracheae 2, metal connecting hose 6 is located between safety valve and the maintenance ball valve, and the main road tracheae also is connected with electro connecting pressure gauge by the second branch road tracheae 3, also is provided with metal connecting hose 7 in the second branch road tracheae.Adorn metal connecting hose 6 and metal connecting hose 7 respectively on the first branch road tracheae 2 in jack unit and the second branch road tracheae 3, this structure makes two branch road gas path pipes of jack unit part have flexibility relatively, therefore the sealing surface of two flanges of jack unit part and pressure-reducing valve group part junction just can guarantee to coincide simultaneously, thereby guarantees good seal.
Claims (2)
