Abstract
The utility model discloses a leak-tightness device on a horizontal type steel ball flashing machine, which can lead the pressure to be slowly increased from zero when starting up immediately after halt interruption maintenance so as to prevent the workpieces and equipment from being damaged due to rapid pressure rising. The device has the following structure: the left end of a cylinder, an accumulator and a hydraulic control one-way valve are connected through a pipe and then are connected with the left end of the cylinder after communicating a change valve for reversing, the change valve is communicated with a tank 6 and a pump; the accumulator and a pressure gage are communicated through a pipe; and a pipe orifice is arranged between the accumulator and the hydraulic control one-way valve and connected with a leak-tightness valve through a pipe. The device is applicable to horizontal type steel ball flashing machines.
Description
Technical field:
The utility model relates to a kind of Leakless valve, is specially adapted to use on horizontal steel ball, the ball grinder.
Background technology:
The hydraulic pressure of control oil cylinder on the existing horizontal steel ball machine; form by oil cylinder and accumulator, hydraulic control one-way valve and reversal valve, Pressure gauge, overflow valve and pump; can not go wrong under normal operation, if fortuitous event need be shut down the maintenance that has a power failure, this moment, pressure was not unloaded down fully; directly pressurization of start back again; this moment, pressure can strengthen suddenly, gently then washed out Pressure gauge, the damage workpiece; consequence was hardly imaginable after damage equipment, heavy then workpiece burst apart.
Summary of the invention:
Task of the present utility model is to propose after shutting down interruption maintenance, and the pressure of starting shooting can only slowly raise from zero, thereby has avoided causing damaging workpiece, the Leakless device on a kind of horizontal steel ball light pearl machine of damage equipment because of pressure sharply raises at once.Task of the present utility model is finished like this, it comprises between oil cylinder left end and accumulator, the hydraulic control one-way valve and being communicated with management, connect the reversal valve commutation again after pipe is connected with the left end of oil cylinder, reversal valve and fuel tank 6 and pump are connected, be communicated with pipe between accumulator and the Pressure gauge, it is characterized in that: open a mouth of pipe between the accumulator hydraulic control one-way valve and connect a Leakless valve with pipe.The utlity model has following effect: the utility model has increased a Leakless valve; next is straight-through in the situation of equipment operate as normal for this valve; this moment, pressure oil was in no leak condition; if shut down suddenly or power failure; Leakless valve just is in closed circuit state; if meet accident; the Leakless valve conducting; pressure oil flows into fuel tank through this valve; pressure is released; when the workman started shooting work again, pressure can only slowly raise from zero, thereby had avoided causing damaging the generation of workpiece, damage equipment or casualty accident because of pressure sharply raises.
Description of drawings:
Fig. 1 is the prior art structural representation, and Fig. 2 is the utility model structural representation.
Drawing explanation: 1, oil cylinder 2, accumulator 3, control check valve 4, reversal valve 4-1 reversal valve 5, pump 6, fuel tank 7, overflow valve 8, Pressure gauge 9, Leakless valve
The specific embodiment:
Describe embodiment in detail in conjunction with above accompanying drawing, be communicated with pipe between oil cylinder 1 left end and accumulator 2, the hydraulic control one-way valve 3, connecting reversal valve 4 again is connected with the oil cylinder right-hand member by pipe after commutating, reversal valve 4-1 and fuel tank 6 and pump 5 are connected, be communicated with (see figure 1) with pipe between accumulator 2 and the Pressure gauge 8.The technical program is to open a mouth of pipe to be connected a Leakless valve 9 with pipe between accumulator 2 and hydraulic control one-way valve 3, this Leakless valve is in closed circuit state always when energising, if outage suddenly takes place, Leakless valve 8 conductings, make the pressure oil of oil cylinder right-hand member be back to fuel tank 6 rapidly, reach the purpose of decompression.
