Abstract
The utility model belongs to a fire-fighting water pressure test instrument, which is composed of a main pipe, a pressure-measuring instrument, a bent pipe, a reducing interface, an interface for pipe screw of a water inlet pipe, an interface for pipe screw of a water outlet pipe and a closed cover. The utility model is characterized in that an exhaust conduit is connected with the main pipe; an exhaust valve for pressure relief is arranged on the exhaust conduit; one end of an exhaust post of the exhaust valve for pressure relief can be connected with a flow guide pipe. Gas stored in a hydrant can be eliminated when the utility model is used; the detection data is accurate; water with pressure can directly flow out through the guide of the exhaust conduit and the exhaust valve; the pollution of the hydrophobic objects of elevator cabs, luxurious decoration, etc. can be avoided; after test, the pressure can be relieved through an exhaust valve for pressure relief; the utility model can prevent the water with pressure from spouting to the body of a testing man.
Description
The utility model relates to a kind of proving installation of indicating fire fighting hydraulic pressure, especially can measure the hydrostatic force of hydrant bolt mouth and the fire fighting hydraulic pressure test chart of discharge pressure.
At present, known fire fighting hydraulic pressure test chart is made up of the person in charge, tensimeter, bend pipe, reducer, two tube tooth interfaces and stifle.The fire fighting hydraulic pressure test chart is positioned on the hydrant bolt mouth, at first be that trapped gas is full of the fire fighting hydraulic pressure test chart in the hydrant in the test process, rather than the band setting-out is full of the fire fighting hydraulic pressure test chart in the hydrant, owing to the compressibility that has of gas, makes that detecting data has certain error; Next, detection finishes, and is full of the band setting-out in the test chart, and the fire fighting hydraulic pressure test chart is difficult for taking off, and when taking off, the splash of band setting-out is avoided on one's body water article and the tester to elevator cab on every side, milli China decoration etc.So having, general fire fighting hydraulic pressure test chart can not carry out the pressure release exhausting problem.
The utility model purpose provides a kind of fire fighting hydraulic pressure test chart, and its energy pressure release and exhaust makes the hydrostatic force and the discharge pressure data of detected hydrant inspection mouth more accurate; Detection finishes, and can take off the fire fighting hydraulic pressure test chart easily; When taking off the fire fighting hydraulic pressure test chart, the elevator cab around avoiding polluting with setting-out, luxurious decoration etc. are avoided on one's body water article and the splash tester.
The purpose of this utility model is achieved in that a kind of fire fighting hydraulic pressure test chart, form by main pipe pressure table, bend pipe, reducer, entry tube tooth interface, water outlet tube tooth interface and stifle, it is characterized in that:, a pressure release vent valve is housed on these exhaust manifolds being responsible for exhaust manifolds of connection on the tube wall.
The exhaust outlet end of pressure release vent valve also can be by mozzle.
Described pressure release vent valve can adopt a ball valve.
Owing to adopt such scheme, can when the test fire fighting hydraulic pressure, open the pressure release vent valve, the gas in the hydrant is discharged, make test data accurate.After test finishes, open the pressure release vent valve, can take off the fire fighting hydraulic pressure test chart easily, manage directed outflow of band setting-out in the guiding fire fighting hydraulic pressure test chart by the guide, avoided the band setting-out in the test chart to pollute the elevator cab of surrounding environment, luxurious decoration etc. and avoided water article and splash on one's body the tester.
The utility model is described in further detail below in conjunction with drawings and Examples.Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the longitudinal profile synoptic diagram that pressure release vent valve of the present utility model adopts ball valve, and wherein Fig. 2 (a) is a ball valve open mode synoptic diagram, and Fig. 2 (b) is a ball valve closed condition synoptic diagram.
As shown in Figure 1, the utility model fire fighting hydraulic pressure test chart is made up of the person in charge 1, tensimeter 2, bend pipe 3, pressure release vent valve 4, reducer 5, entry tube tooth interface 6a, water outlet tube tooth interface 6b and stifle 7, be responsible for and be connected with exhaust manifolds 8 on the tube wall, a pressure release vent valve 4 be housed on it, the exhaust outlet end of pressure release vent valve also can connect a mozzle 9.
As shown in Figure 2, pressure release vent valve 4 is a ball valve, and when the handle 10 of ball valve and valve body 12 were parallel, spool 11 was connected with exhaust manifolds 8, and pressure release vent valve 4 is opened, and can guide directed outflow of band setting-out in the test chart; When the handle 10 of pressure release vent valve 4 and valve body 12 were vertical, pressure release vent valve 4 was closed, the hydraulic pressure in can the test lead.Adopt ball valve sealing good and durable.
When testing the hydrostatic force of hydrant bolt mouth, water outlet tube tooth interface 6b connects a stifle 7 by the pipe tooth, and according to the size of hydrant bolt mouth diameter, entry tube tooth interface 6a can link to each other with hydrant bolt mouth by a reducer 5.Slowly open hydrant key, pressure release vent valve 4 is opened, get rid of trapped gas in the hydrant, after waiting to flow out water, close pressure release vent valve 4, make the band setting-out be full of the fire fighting hydraulic pressure test chart, the force value of reading from tensimeter 2 is the hydrostatic force of hydrant bolt mouth.Detection finishes, open pressure release vent valve 4, can be by mozzle 9 with certain direction emission gases of purpose or band setting-out, release pressure, from hydrant, take off the fire fighting hydraulic pressure test chart easily, avoid polluting the elevator cab of surrounding environment, luxurious decoration etc. simultaneously and avoid on one's body water article and the splash tester with setting-out.
When the discharge pressure of test hydrant bolt mouth, the stifle 7 that takes off on the fire fighting hydraulic pressure test chart connects fire hose and hydraulic giant, closes pressure release vent valve 4, opens hose saddle to the normal water outlet of hydraulic giant, produce and enrich water column, this moment, the force value of tensimeter 2 was hydrant bolt mouth discharge pressure value.
