The vacuum booster durable test stand is a kind of of pressure durable test stand, the structure and the principle of work of vacuum booster durable test stand and pressure durable test stand are basic identical, usually adopt hydraulic means to promote pressure regulator valve, adopt resetting means that pressure regulator valve is resetted, resetting means is made of the elastomeric pad that is superimposed.After using, find, the pressure durable test stand of this kind structure whenever carries out test about 50,000 times and just has the elastomeric pad fracture of part or damage, and a complete long duration test needs more than 330,000 times usually, because the damage of pad, need in the process of the test repeatedly testing equipment to be safeguarded, not only have a strong impact on production efficiency, test mass also can't be protected.
Also there are some that the pressure durable test stand is carried out improved technical scheme in the prior art, as the Chinese patent notification number is CN201110806Y, date of declaration is on September 3rd, 2008, patent name discloses a kind of technical scheme of pressure durable test stand for the creativity and innovation of " a kind of pressure switch durable test stand ", this scheme is improved the hydraulic means of pressure durable test stand, and its weak point is that the technical matters of resetting means in use not being damaged easily proposes improvement project.
The utility model content
The purpose of this utility model is to solve the technical matters that the pressure regulator valve resetting means on the vacuum booster durable test stand in the prior art in use damages easily, and a kind of simple in structure, vacuum booster durable test stand pressure regulator valve resetting means that useful life longevity increases substantially is provided.
In order to solve the problems of the technologies described above, the utility model has adopted following technical proposals: a kind of vacuum booster durable test stand pressure regulator valve resetting means, comprise frame, pressure regulator valve, described frame is provided with the spool orienting sleeve, the front end of pressure regulator valve is a valve seat for the spool rear end, spool and spool orienting sleeve flexibly connect, and are provided with spring between valve seat and the spool orienting sleeve.
The utility model is improvements over the prior art, the resetting means of prior art is the elastomeric pad that is provided with some stacks between valve seat and spool orienting sleeve, utilize the elastic force of elastomeric pad that pressure regulator valve is resetted, resetting means of the present utility model adopts spring to replace elastomeric pad, utilize the elastic force of spring that pressure regulator valve is resetted, increased substantially reliability and the durability of vacuum booster durable test stand more than 1,000,000 times the serviceable life of resetting means of the present utility model.
As preferably, described spring and spool socket.The utility model adopts a spring, and the two ends of spring prop up spool orienting sleeve and valve seat respectively, and spring housing is connected on the outside cylinder of spool.
As preferably, be provided with the spring orienting sleeve between described spring and the spool, spring orienting sleeve and spool socket.For preventing that spring inside diameter from off-centre or crooked occurring greater than the spring of valve core diameter, between spring and spool, increased the spring orienting sleeve, the spring orienting sleeve is a circle ring column.
As preferably, described spool and valve seat are right cylinder, and spool is structure as a whole with valve seat and is coaxial.The front end of pressure regulator valve is a spool, and the rear end is a valve seat, and the end that is enclosed within the spring on the spool props up on the step of valve seat and spool formation.
As preferably, described spool orienting sleeve is a circle ring column, and the center of spool orienting sleeve is a valve core through hole, and an end of spool orienting sleeve is fixedlyed connected with frame.The spool orienting sleeve plays the effect of supporting spool and the motion of spool being led, and the external diameter of spool cooperates with the bore clearance of valve core through hole.
As preferably, the rear end of described pressure regulator valve is provided with hydraulic means, and pressure regulator valve is fixedlyed connected with hydraulic means.Pressure regulator valve is promoted by hydraulic means, and under the highly pressurised liquid effect, hydraulic means promotes pressure regulator valve, and during pressure release, spring promotes pressure regulator valve and resets.
Novel simple in structure of this test, easy for installation, solved vacuum booster durable test stand resetting means short technical matters in serviceable life in the prior art, 50,000 tests of resetting means originally just need to be serviced, played the beneficial effect that improve test efficiency, reduction test loss, ensure test accuracy more than 1,000,000 times serviceable life of the present utility model.
