Summary of the invention
The utility model object is to overcome the deficiencies in the prior art, provides a kind of quick mounting type pressure testing device.The utility model structure is simple, easy to use, and without the need to dismounting when using, decreases breakthrough and produce, and can switch the tensimeter of different range fast, shorten tensimeter replacing construction.。
To achieve these goals, the utility model have employed following technical scheme:
A kind of quick mounting type pressure testing device, comprises test pump, retaining valve, ball valve II, threeway gauge valve, tensimeter I and pressure Table II; Described test pump is connected with the fluid intake of retaining valve by high-pressure hose I, and the fluid egress point of described retaining valve connects one end of pressure testing pipe I, and the other end of pressure testing pipe I treats pressure testing equipment by high-pressure hose II access; One end of described ball valve II, the import of threeway gauge valve are connected with pressure testing pipe I respectively by fluid hose, pressure testing pipe II; The other end of described ball valve II connects injection bleed outlet; Two outlets Bonding pressure Table I and pressure Table II respectively of described threeway gauge valve.
Described test pump provides pressure fluid for device; Described retaining valve is made pressure current can only be flowed into by retaining valve fluid intake and does not flow out by retaining valve fluid egress point, the stability of assurance device pressure.
By the high-pressure hose of both sides respectively with test pump with treat that pressure testing equipment is connected fast, shorten the set-up time; For the pressure testing equipment of different range, by the adjustment of the operation valve of threeway gauge valve, select suitable tensimeter to pressure testing equipment pressure testing, improve experimental precision.
Further, also comprise ball valve I, described ball valve I and retaining valve are connected in series.
After retaining valve, be provided with ball valve I, can prevent from causing because retaining valve is poorly sealed liquid to flow back to the situation of test pump after making to close ball valve I, improve test reliability.
Further, in-line relief valve is provided with between described ball valve II and threeway gauge valve.
In-line relief valve plays safeguard protection effect in a device, and when device pressure exceedes setting, in-line relief valve is opened, and by a part of fluid expulsion in device, make device pressure be no more than permissible value, thus assurance device is not damaged because of hypertonia.
The principle of work of the utility model device and step:
By high-pressure hose II with treat that pressure testing equipment is connected, open threeway gauge valve, tensimeter I or pressure Table II be communicated with pressure testing pipe II.Opening ball valve II, by injecting bleed outlet to after filling test fluid in pressure testing equipment, closing ball valve II;
Then open ball valve I, operation test pump continue to treat pressure testing equipment inject fluid, until tensimeter I or pressure Table II displayed value consistent with test pressure value; Then ball valve I is closed, until treat the pressure test end-of-job of pressure testing equipment;
When device pressure exceedes setting, in-line relief valve is opened, and by a part of fluid expulsion in device, make device pressure be no more than permissible value, thus assurance device is not damaged because of hypertonia;
After pressure testing terminates, opening ball valve II, by injecting bleed outlet by test fluid evacuation, and taking the connection between high-pressure hose II and pressure testing equipment apart.
The beneficial effects of the utility model:
1. the utility model adopts modularization to install, and without the need to dismounting during use, decreases breakthrough.
2. the utility model is by the high-pressure hose of both sides respectively with test pump with treat that pressure testing equipment is connected fast, shortens the set-up time.
3. the utility model is switched the tensimeter of different range fast by threeway gauge valve, shortens tensimeter replacing construction.
4. the utility model is for the tensimeter of the different range of different tests pressure selection, improves test accuracy.
