Abstract
The utility model discloses a loading gate gurgle valve on jack, relating to the jack technical field. The loading gate gurgle valve on jack is composed of a vat seat, an oil discharge bolt, a sealing ring, an elastic body as an oil discharge thimble, steel balls, and an oil discharge passage which are integrated with a jack main body. The oil discharge bolt and the sealing ring are installed on the vat seat by the oil discharge bolt through the thread, and steel balls are installed on the oil discharge passage; the elastic body is installed between the oil discharge bolt and steel balls. During using, the utility model can be installed on the a manual liquid pressure or a pneumatic power jack; under the function of the elastic body, the loading gate gurgle valve on jack can regulate the flow quantity that high pressure oils enter the oil storing barrel of the jack from the oil discharge passage by steel balls and the oil discharge passage, which can realize slowly descending of the loading on jack and gradatim finish operating of loading on jack. By using the utility model, the descending speed can be controlled during loading on jack, which can get the descending speed of the jack is averagely not more than 0.15 metres / second and can get the quality conform to Europe standard EN1494: 2000.
Description
Technical field: technical solutions of the utility model relate to technical field of jacks, particularly are installed in the oil drain valve on the jack.
Background technique; In the prior art, the oil drain valve of jack is made up of draining thimble, steel ball and the draining passage of the cylinder seat that is connected as a single entity with the jack main body, draining bolt, seal ring, steel, draining bolt, seal ring are installed on the cylinder seat by the draining bolt thread, steel ball is installed on the draining passage that is connected with the zone of high pressure, and the draining thimble is installed between draining bolt and steel ball.The jack oil drain valve of this structure is tightened the draining bolt when jack is worked, under the effect of draining bolt, the draining thimble by steel holds out against steel ball, prevents the leakage of high pressure oil, makes the jack proper functioning; After the work of jack was finished, the unloading of jack realized by oil drain valve, unclamps the draining bolt, and high pressure oil flows to fuel tank by steel ball, the draining passage that is connected with fuel tank immediately; Exist by the jack oil drain valve of analyzing visible said structure and to make jack unload at present reduction of speed to spend soon, can not realize that the jack rate of descent is controlled, and also have technical problem of poor safety during the jack unloading.
Summary of the invention:
Technical problem to be solved in the utility model is, designs a kind of jack load oil drain valve, can not realize that to solve existing jack oil drain valve the jack rate of descent is controlled, and has technical problem of poor safety during the jack unloading.
The basic technical scheme of the utility model technical solution problem is: it is made up of the cylinder seat, draining bolt, seal ring, draining thimble, steel ball and the draining passage that are connected as a single entity with the jack main body, draining bolt, seal ring are installed on the cylinder seat by the draining bolt thread, steel ball is installed on the draining passage, the draining thimble is installed between draining bolt and steel ball, and its draining thimble is an elastomer; Like this, when jack unloaded, elastomeric effect can realize limiting the dredge oil amount of jack, reached the effect that reduces the jack rate of descent.
According to above-mentioned basic technical scheme, elastomer can be the draining spring.
Can be equipped with on the draining spring and the contacted spring seat of steel ball.
Owing to adopt technique scheme, when the utility model uses, it is installed on manual hydraulic pressure or the pneumatic jack, under elastomeric effect, the can regulate high pressure oil enters the flow of the fuel tank of jack through steel ball, draining passage from the draining passage, realize the slow decline under the jack load, progressively finish the running of jack unloading; The control of rate of descent made the average rate of descent maximum of jack be no more than 0.15 meter per second when its use can realize the jack unloading, made its quality conform European standard EN1494:2000.
Description of drawings:
Fig. 1 is a kind of example structure schematic representation of optimal design.
In the drawings: draining bolt 1; Seal ring 2; Draining spring 3; Spring seat 4; Steel ball 5; Cylinder seat 6; Draining passage 7,8.
Embodiment:
In conjunction with Fig. 1, a kind of jack load oil drain valve, it is made up of the cylinder seat 6, draining bolt 1, seal ring 2, elastomer, steel ball 5, the draining passage 7 and 8 that are connected as a single entity with the jack main body; Draining bolt 1, seal ring 2 are installed on the cylinder seat 6 by draining bolt 1 screw thread, and steel ball 5 is installed between draining passage 7 and 8, and elastomer is installed between draining bolt 1, the steel ball 5; Elastomer is a draining spring 3 in the present embodiment, can be equipped with on the draining spring 3 and steel ball 5 contacted spring seats 4.
The utility model is installed on the jack, during its work, turn draining bolt 1, under the effect of draining spring 3, the can regulate high pressure oil enters the flow of the fuel tank of jack through steel ball 5, draining passage 8 from draining passage 7, realize the slow decline under the jack load, progressively finish the running of jack unloading.
