Abstract
The utility model provides a built -in pressure regulating valve's of fuel filter leakproofness testing arrangement, includes a container, a manometer, an air supply and a gas tube, is provided with transparent liquid in the container, and the gas tube is connected with the air supply, and the manometer is connected on gas tube or air supply, and the one end of gas tube is provided with pressure regulating valve oil inlet connector, and pressure regulating valve oil inlet connector lies in the container and lies in transparent liquid's liquid surface below. Be provided with a pressure regulating valve oil -out end cap in the container, pressure regulating valve oil -out end cap is located transparent liquid's liquid surface below. The pressure regulating valve that will await measuring place in the container and the submergence in transparent liquid, utilize the sealed pressure regulating valve's of end cap oil -out, be connected pressure regulating valve oil inlet connector and the pressure regulating valve oil inlet of gas tube one end, utilize the air supply to aerify pressure regulating valve, when charged pressure reached the setting value, whether observation valve body outside the gassing to judge whether the pressure regulating valve that awaits measuring reveals.
Description
Technical field:
The utility model relates to mechanical field, particularly relates to fuel filter, particularly the tightness measuring device of the built-in pressure-regulating valve of a kind of fuel filter.
Background technology:
Fuel filter inside is provided with pressure-regulating valve, and pressure-regulating valve is the key component keeping fuel system internal pressure stabilises, because it is positioned at filter cleaner inside, cannot carry out performing leak test to it.But when pressure-regulating valve exists seal defect, fuel oil can be caused directly to get back to fuel tank without valve body, the internal pressure of fuel system reduces, and can not meet automotive fuel oil system to pressure controlled requirement
Summary of the invention:
The purpose of this utility model is the tightness measuring device providing the built-in pressure-regulating valve of a kind of fuel filter, and the tightness measuring device of the described built-in pressure-regulating valve of this fuel filter will solve in prior art the technical matters of the sealing cannot testing the built-in pressure-regulating valve of fuel filter.
The tightness measuring device of the built-in pressure-regulating valve of this fuel filter of the present utility model, comprise a container, tensimeter, a source of the gas and a gas-filled tube, wherein, transparency liquid is provided with in described container, described gas-filled tube is connected with described source of the gas, described tensimeter is connected on gas-filled tube or source of the gas, one end of gas-filled tube is provided with pressure-regulating valve oil-in connector, and described pressure-regulating valve oil-in connector is positioned at container and is positioned at below the liquid level of described transparency liquid.
Further, be provided with a pressure-regulating valve oil-out plug in container, described pressure-regulating valve oil-out plug is positioned at below the liquid level of transparency liquid.
Principle of work of the present utility model is: to be placed into by testing pressure variable valve in container and to be immersed in transparency liquid, utilize the oil-out of pressure-regulating valve oil-out plug sealing load variable valve, the pressure-regulating valve oil-in connector of gas-filled tube one end is connected with pressure-regulating valve oil-in, source of the gas is utilized to inflate pressure-regulating valve, when charge pressure reaches setting value, whether inspecting valve external body produces bubble, thus judges whether testing pressure variable valve is revealed.
The utility model is compared with prior art, and its effect is actively with obvious.The utility model utilizes container, transparency liquid, tensimeter, source of the gas and gas-filled tube to form pick-up unit, testing pressure variable valve to be placed in container and to be immersed in transparency liquid, utilize the oil-out of pressure-regulating valve oil-out plug sealing load variable valve, the pressure-regulating valve oil-in connector of gas-filled tube one end is connected with pressure-regulating valve oil-in, source of the gas is utilized to inflate pressure-regulating valve, when charge pressure reaches setting value, whether inspecting valve external body produces bubble.The oil circuit trend of source of the gas, gas-filled tube and pressure-regulating valve oil-out plug simulation fuel system, and can adjust pressure size according to demand, can directly whether test pressure variable valve sealing property be qualified.
Accompanying drawing illustrates:
Fig. 1 is the schematic diagram of the tightness measuring device of the built-in pressure-regulating valve of fuel filter of the present utility model.
