Abstract
An analog flow valve comprises a valve body (1), a metering-orifice body (2), a plunger piston (3) and an electromagnetic switch assembly (4), wherein a plunger piston hole (11) and an oil path hole (12) which are arranged in a cross structure are arranged in the valve body (1), the electromagnetic switch assembly (4) is mounted on the valve body (1) and is located at one end of the plunger piston hole (11), a piston head portion (41) of the electromagnetic switch assembly (4) is located in the plunger piston hole (11) of the valve body (1), the plunger piston (3) is located in the plunger piston hole (11) of the valve body (1) and is mounted on the piston head portion (41) of the electromagnetic switch assembly (4), the metering-orifice body (2) is in threaded connection with an oil path outlet of the oil path hole (12) of the valve body (1), and the center of the metering-orifice body (2) is provided with a through-hole (21). The analog flow valve is particularly applicable to pressure and flow tests of oil pumps.
Description
Technical field
The utility model relates to a kind of oil pump testing installation that relates to, particularly a kind of analog stream metered valve.
Background technique
At present, oil pump is carried out flow performance when test on testing installation, all how much with the measured flow of rated pressure value and flowmeter, and as the whether qualified standard of deteminate machine oil pump; But because testing system apparatus is difficult to standard, be difficult to consistently with the motor actual working environment, promptly the testing environment of oil pump and working environment is different, can not truly reflect the actual conditions of engine lubrication system flow.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art and a kind of analog stream metered valve is provided, and it is simple in structure, flowmeter that can the alternative structure complexity.
The technical solution of the utility model is: a kind of analog stream metered valve, and it comprises valve body, jet block, plunger and electromagnetic switch component composition; Have into the plunger hole and the oil circuit hole of criss-crossing in the valve body, electromagnetic switch component is installed on the valve body and is positioned at an end of plunger hole, the piston crown of electromagnetic switch component is positioned at the plunger hole of valve body, and plunger is positioned at the plunger hole of valve body and is installed on the piston crown of electromagnetic switch component; Jet block is threaded in the oil circuit outlet port in the oil circuit hole of valve body, and the jet block center is provided with a through hole.
The further technological scheme of the utility model is: the minimum-value aperture D of the through hole on the described jet block is for becoming plurality of specifications according to tested oil pump institute mounted engine needs flow size design.
The utility model further technological scheme is: it also comprises seal ring and plug screw, and seal ring is installed in the end that plunger is connected with the piston crown of electromagnetic switch component, and the plug screw is installed in the other end of plunger hole by being threaded.
The utility model compared with prior art has following characteristics:
1, its novelty simple in structure, stable performance, reliable operation;
2, it is convenient to install, conveniently debugs, need not maintenance;
3, the flowmeter of this valve energy alternative structure complexity greatly reduces cost of production.
Below in conjunction with the drawings and specific embodiments detailed structure of the present utility model is further described.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
