Embodiment Construction

[0010] The main steps of the anti-seize valve structure of the hydraulic system described in the embodiment of the present invention include:

[0011] ⑴First, the valve body structure is a cone valve type anti-seize valve, and an outer valve core is placed outside the main valve core to form a double valve core structure. The other end of the main spool is provided with a pressure relief port and the pressure relief port is in the shape of a bell mouth;

[0012] ⑵When the rotary pressure is less than the setting value of the anti-seize valve, the adjusting main spool moves left together under the action of rotary pressure oil and does not touch the adjusting rod;

[0013] (3) When the rotary pressure is greater than the setting value of the anti-seize valve, the main valve core stops moving due to the restriction of the adjusting rod, while the outer valve core continues to move to the left, the pressure relief port of the valve core is opened, and the propulsion pressure decr...

Abstract

The invention discloses an anti-jamming valve structure of a hydraulic system. Firstly, a valve body structure is a cone valve type anti-jamming valve, an outer valve core is sheathed on the outside of a main valve core to form a double-valve core structure, an adjusting rod penetrates through the tail of the outer valve core and penetrates into the main valve core, meanwhile, the other end of the main valve core is provided with a pressure release port, and the pressure release port forms a horn shape. When the rotating pressure is smaller than the setting value of the anti-jamming valve, the main valve core is adjusted and moved to the left under the action of rotating hydraulic fluid, and the main valve core is not in contact with the adjusting rod. The anti-jamming valve structure has the beneficial effects that the problem of drill jamming is effectively solved, the normal drilling of a rock drill is ensured, the production efficiency is improved, the running precision of the machine is favorably improved, the abrasion is reduced, the service life is prolonged, the force on the machine body is assisted, and the like.

Description

technical field [0001] The invention relates to the technical field of hydraulic pressure, in particular to an anti-stick valve structure of a hydraulic system. Background technique [0002] The hydraulic system has the advantages of large power, good adjustability of working pressure and flow, and heat can be brought back to the oil tank. The hydraulic system device can generate more power than other devices. Under the same power, the hydraulic device is small in size, Light weight, high power density, compact structure. The down-the-hole drilling rig is a kind of engineering machinery for drilling minerals and rocks. It is a device in which the impactor dives into the hole and directly impacts the drill bit, and the rotary mechanism drives the drill pipe to rotate outside the hole to drill into the rock. It is mainly used for open-pit mining, Rock drilling in various projects such as building foundations, water conservancy, power stations, building materials, transportati...
