Abstract
The utility model discloses a down-the-hole drill shock valve which is characterized by comprising a lengthened valve body. A lengthened valve core is sleeved in the lengthened valve body in a matched mode, a core shaft of the lengthened valve core is provided with a non-transparent ventilation hole from one end to the other end, a circumferential hole communicated with the ventilation hole is arranged on the circumference of the lengthened valve core, an air outlet hole corresponding to the circumferential hole is positioned on the lengthened valve body, the non-transparent end of the lengthened valve core is connected with a handle, a press cover where high pressure gas is filled is connected at the other end of the lengthened valve body, and a pressure meter connected with the high pressure gas is arranged on the lengthened valve body. Compared with the prior art, the down-the-hole drill shock valve has the advantages of being good in leakage prevention effect and long in service life.
Description
Technical field
The utility model relates to a kind of down-the-hole drill dash valve.
Background technique
Original pneumatic control valve is two-in-one function, can realize impacting and lifting function, it comprises valve body, be provided with spool in the valve body, because realizing two independent controls, therefore adopted two independent spools, two independent spool circumferential direction are provided with radial hole, be provided with seal ring between the valve body, be connected with handle on each spool.
In the above structure, when independent valve body work, the phenomenon that certainly will have gas leakage between the hole on the radial hole of another spool and the radial hole of valve body and the valve body, in addition owing to being provided with seal ring between two valve bodies, regulate both apart from the time, pine the phenomenon of easy generation gas leakage, build-up of pressure is not enough, can't work; The tight life-span decrease of seal ring needs often to change, and uses extremely inconvenient.
Summary of the invention
For overcoming above problem, of the present utility modelly be to provide a kind of down-the-hole drill dash valve, this device has advantages of that obturation effect is good, long service life.
For achieving the above object, the technical solution of the utility model is:
A kind of down-the-hole drill dash valve, comprise the lengthening valve body, lengthen the interior engage sleeves of valve body and be provided with the lengthening spool, the mandrel that lengthens spool is provided with non-penetrating vent by an end to its other end, lengthen the spool side face and be provided with the therewith radial hole of vent connection, lengthen valve body and be provided with therewith air outlet hole corresponding to radial hole, the non-penetrating end that lengthens spool is connected with handle, and the other end that lengthens valve body is provided with and is connected with the gland that is connected with pressurized gas.
Further, lengthen valve body and be provided with the barometer that is connected with pressurized gas.
Further, described lengthening valve body is provided with seal ring with lengthening between the spool at least at an end that is provided with handle.
Further, described gland is provided with corresponding bolt hole with lengthening valve body, and both seal ring bolts connect.
Further, described spool is the form of multidiameter shaft, lengthens the shoulder hole form of valve body for cooperating.
Further, the stub end of multidiameter shaft be positioned at lengthen spool be provided with handle to side.
Further, described gland with lengthen valve body on the corresponding bolt ear seat that is provided with, gland is connected by ear seat bolt with the lengthening valve body.
Further, be provided with cell body along generatrix direction on the described spool side face, valve body is provided with the through hole corresponding with cell body, is provided with locating stud by elastic device on the through hole.
Further, the air outlet hole of described lengthening spool is the slotted hole along its axis.
Working principle of the present utility model namely reaches beneficial effect:
The utility model is arranged with a lengthening spool by lengthening in the valve body, by being connected percussion mechanism with air outlet hole, realize impact function, handle and circumferential pitch-row are from increase, lengthened between the seal area of spool and valve body, sealing effect is better, the phenomenon that can not leak air.
Spool adopts non-transparent design, and the closest approach that leaks so just only is present on the circumferential hole, and circumferential hole and handle distance are larger, and gas leakage is able to shutoff.
Be provided with seal ring between spool and the valve body, further strengthen sealing effect, prevent gas leakage.
Gland and valve body are that bolt sleeve adds seal ring and is fixedly connected with, and compare other Placements, and good sealing effect further prevents gas leakage.
