Abstract
The utility model discloses an external jack for a technical grade check valve, which comprises a jack body and an integral valve block, wherein an installation joint for installing a power assisting device is arranged on the integral valve block, a high-pressure oil joint and an oil pond joint are arranged at the opposite side of the installation joint, and four through holes for installing the integral valve block on the bottom plate of the jack by screws are arranged at the peripheries of the high-pressure oil joint and the oil pond joint. Compared with the prior art, the check valve which is originally arranged on the bottom plate of the jack is integrally arranged on a steel so as to save more special steel and choose a better thermal treatment way, in this case, the service life of the jack is effectively prolonged, and the normal use of the jack can be recovered only by replacing the integral valve block when the jack breaks down after long time use, thereby effectively reducing the use cost of the users.
Description
Technical field
The utility model relates to technical field of jacks, particularly relates to a kind of industrial grade check valve external jack.
Background technology
At present, the integrated external jack of industrial grade check valve in use, for the lifting weight, must have high pressure oil to inject and can reach application target.When the oil pump high pressure oil, check valve is bearing alternative pressure greatly, to such an extent as to present jack check valve very easily damage, thereby cause jack to scrap.
The utility model content
For solving the problems of the technologies described above, it is fine that the purpose of this utility model provides a kind of durability, easy to process, installs simply, uses extensive, the easy industrial grade check valve of maintain and replace external jack.
A kind of industrial grade check valve external jack of the present utility model, comprise body and integrated valve block, on described integrated valve block, be provided with a mounting interface that supplies work-saving device to pack into, reverse side at this mounting interface is provided with high pressure oil interface and oil sump interface, and the circumferential distribution of described high pressure oil interface and oil sump interface has four described integrated valve block is installed in through hole on the jack base plate with four screws.
Wherein, the place is provided with oil sucting one-way valve and high-pressure oil passage at described mounting interface, and oil sucting one-way valve links to each other with oil sump, is provided with the high pressure oil check valve in described high pressure oil interface, and the high pressure oil check valve links to each other with high-pressure oil passage.
Wherein, described integrated valve block is square steel.
Wherein, described work-saving device comprises hand pressurizer, air assisted pump or electric boosted pump.
Compared with prior art, jack was designed check valve on base plate originally, integrated design is on steel, better more save and use special rolling-mill section, and can better select heat treatment mode for use, so just the service life of energy actv. raising jack, even break down after the practical long period, as long as change integrated valve block, jack just can recover normal use, just can effectively reduce user's use cost.The valve piece is selected special rolling-mill section for use, also can better plan as a whole cost, the quality of jack, also more can economize on resources, and promotes durability, and the convenient processing of energy, replacing are conveniently.Can not cause check valve to break, will keep in repair or change the base plate of whole jack.

The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used to illustrate the utility model, but are not used for limiting scope of the present utility model.
As Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, a kind of industrial grade check valve external jack, comprise body 4 and integrated valve block 1, on integrated valve block 1, be provided with a mounting interface 11 that supplies work-saving device to pack into, reverse side at this mounting interface 11 is provided with high pressure oil interface 12 and oil sump interface 13, and the circumferential distribution of high pressure oil interface 12 and oil sump interface 13 has four four screws 2 of integrated valve block 1 usefulness are installed in through hole 14 on the jack base plate 3.Work-saving device described in the present embodiment adopts hand pressurizer.
Industrial grade check valve external jack of the present utility model, be provided with oil sucting one-way valve 15 and high-pressure oil passage 17 at mounting interface 11 places, oil sucting one-way valve 15 links to each other with oil sump, be provided with high pressure oil check valve 16 for 12 li at the high pressure oil interface, high pressure oil check valve 16 links to each other with high-pressure oil passage 17, high pressure oil check valve closure when so just forming a hand pressurizer and mentioning, oil sucting one-way valve is opened, make the oil cylinder of hand pressurizer suck oil, when hand pressurizer presses down, under the effect of pressure, make the oil sucting one-way valve sealing, and the high pressure oil one-way valve opens makes high pressure oil inject the load-bearing hydraulic actuating cylinder, thereby makes jack hydraulic cylinder jack-up.
Industrial grade check valve external jack of the present utility model, integrated valve block 1 is square steel, for alleviating pts wt, forges into convex and also can.
The work-saving device of packing in the mounting interface 11 that supplies work-saving device to pack into not only can adopt hand pressurizer, also can adopt air assisted pump or electric boosted pump.
The utility model designed check valve on base plate originally with jack, integrated design is on steel, better more save and use special rolling-mill section, and can better select heat treatment mode for use, so just the service life of energy actv. raising jack,, need only and change integrated valve block even break down after the practical long period, jack just can recover normal use, just can effectively reduce user's use cost.The valve piece is selected special rolling-mill section for use, also can better plan as a whole cost, the quality of jack, also more can economize on resources, and promotes durability, and the convenient processing of energy, replacing are conveniently.Can not cause check valve to break, will keep in repair or change the base plate of whole jack.
The above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
