Abstract
The invention discloses an external jack integrated valve block structure, which comprises an integrated valve block; a mounting interface for mounting in a jack hand cranking device is arranged on the integrated valve block; a high pressure oil interface and an oil bath interface are arranged on the back side of the mounting interface; and four through holes for mounting the integrated valve block on a bottom plate of the jack are distributed surrounding the high pressure oil interface and the oil bath interface. Compared with the prior art, a check valve of the jack originally designed on the bottom plate is integrally designed on a piece of steel, thus better using and saving special steel as well as better selecting thermal treatment ways; therefore, the service life of the jack can be effectively prolonged; and even if the jack is failed after long-term service, the jack can be resumed and used normally as long as the integrated valve block is replaced, thus being capable of effectively reducing the use cost of users.
Description
Technical field
The utility model relates to technical field of jacks, particularly relates to a kind of external jack integrated valve block structure.
Background technology
At present, the integrated external jack of industrial grade check valve, in the jack use, the position of easy damage is a check valve, because check valve is bearing alternative pressure greatly.
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 external jack of maintain and replace integrated valve block structure.
External jack integrated valve block structure of the present utility model, comprise integrated valve block, on integrated valve block, be provided with a mounting interface that supplies the jack manual setter 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.
External jack integrated valve block structure of the present utility model, the place is provided with oil sucting one-way valve and high-pressure oil passage at described mounting interface, 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.
External jack integrated valve block structure of the present utility model, described integrated valve block is square steel.
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.

Fig. 2 is the block diagram of integrated valve block in the utility model external jack integrated valve block structure;
Fig. 3 is the lateral plan of integrated valve block;
Fig. 4 is the section-drawing of integrated valve block.
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 shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of external jack integrated valve block structure, comprise integrated valve block 1, on integrated valve block 1, be provided with a mounting interface 11 that supplies the jack manual setter 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.
External jack integrated valve block structure 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 manual setter and mentioning, oil sucting one-way valve is opened, make the oil cylinder of manual setter suck oil, when manual setter 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.
External jack integrated valve block structure of the present utility model, integrated valve block 1 is square steel, for alleviating pts wt, forges into convex and also can.
The jack manual setter of packing in the mounting interface 11 that supplies the jack manual setter to pack into can replace with Pneumatic booster or Electric booster.
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.
