The utility model is composed of a valve body, a pressure gauge, a connecting nut, an inflating mechanism and a gas-discharging mechanism. The valve body and the pressure gauge are fixedly connected through a pressure tap, an aerating mechanism is connected with the valve body, and the gas-discharging mechanism is arranged on the valve body. One end of a connecting nut is connected with the valve body, and the other end is connected with the oil-gas spring through a one-way valve. A gasket is arranged between the pressure gauge and the pressure tap. The aerating mechanism is composed of an aerating flexible pipe and a transfer joint, the aerating flexible pipe is fixedly connected with the transfer joint, and the transfer joint is connected with a gas source. The gas-discharging mechanism is composed of a gas-discharging needle, a push rod handwheel and a gas-discharging needle plug. The gas-discharging needle is fixedly connected with the push rod handwheel, and is connected with the valve body, and the gas-discharging needle plug is arranged on the gas-discharging needle. A plug cap is arranged on the valve body. The utility model can carry out the pressure test experiment to the oil-gas spring or an oil cylinder, and has the advantages of reasonable structure and easy fabrication. The utility model has the characteristic that the oil-gas spring can be continuously tested under the pressure with arbitrary number values.
Description
(1) technical field
The utility model relates to a kind of inflation means of deflation, belongs to hydro-pneumatic spring pressure test technical field.
(2) background technique
At present when hydro-pneumatic spring is carried out pressure test, use be the constant-pressure test mode.The defective of this mode is: by gas charging valve hydro-pneumatic spring is inflated, test pressure is fixed; When changing test pressure, need be inflated to another fixed pressure value again.Can not carry out the continuous pressure test under the pressure arbitrarily to hydro-pneumatic spring.
(3) summary of the invention
At the deficiencies in the prior art, that the utility model provides is rational in infrastructure, easy to manufacture, can carry out a kind of inflation means of deflation of follow-on test under the pressure of any number to hydro-pneumatic spring.
A kind of inflation means of deflation, form by valve body, pressure gauge, attaching nut, inflation mechanism and air-release mechanism, valve body is fixedlyed connected by GAUGE CONNECTOR with pressure gauge, inflation mechanism is connected with valve body, valve body is provided with air-release mechanism, attaching nut's one end is connected with valve body, and the other end is connected with hydro-pneumatic spring by one-way valve.
Be provided with packing ring between pressure gauge and the pressure gauge outfit.
Inflation mechanism is made up of inflated hose and adapter coupling, and inflated hose is fixedlyed connected with adapter coupling, and adapter coupling is connected with source of the gas.
Air-release mechanism is made up of venting pin, push rod handwheel and venting pin plug, and the venting pin that can rotate in push rod is fixedlyed connected with venting pin plug, and is connected with valve body by the push rod handwheel is solid.
Valve body is provided with a blocking cap.
When hydro-pneumatic spring is inflated, rotate the push rod handwheel on the air-release mechanism, open one-way valve, make venting pin plug block the venting pin, connect adapter coupling and source of the gas on the inflation mechanism, the inflation means of deflation begins the hydro-pneumatic spring inflation, and in the process of inflation, the pressure gauge outfit shows the pressure of hydro-pneumatic spring at any time.During venting, rotate the push rod handwheel on the air-release mechanism, close one-way valve, unload inflation mechanism, change the outfit and go up blocking cap, rotate the push rod handwheel on the air-release mechanism again, open one-way valve, rotate venting pin plug gently, the gas in the hydro-pneumatic spring is emitted from valve body.
The utility model also can a pair of various cylinder bodies fills, the blow off pressure test.
The utlity model has characteristics rational in infrastructure, easy to manufacture, as can to carry out follow-on test under the pressure of any number to hydro-pneumatic spring.
