Problems solved by technology

During the working process of the valve in the prior art (that is, glue), the high-pressure glue directly erodes the valve seat and the sealing surface of the valve core, which accelerates the wear of the valve and greatly shortens the life of the valve.

Embodiment Construction

[0016] figure 1 It is a schematic diagram of the structure of the present invention. As shown in the figure, the present invention provides a non-erosion restrictor valve for the sealing surface of a glue gun, which includes a valve seat 2 and a valve core arranged in the valve seat 2 3 and the valve core 3 can reciprocate along the axial direction of the valve seat 2. The reciprocating motion of the valve core 3 is driven by the coaxially fixed valve stem 7 of the valve core 3, and the outer diameter of the valve core 3 is smaller than The inner diameter of the valve seat 2 cooperates with the inner side wall of the middle part of the valve seat 2 to form a restrictive channel 4 for buffering the glue. The restrictive valve for the sealing surface of the glue gun of the present invention is not eroded, Through the restricting channel, the high-pressure glue is buffered in the inner middle of the valve seat, which can effectively prevent the high-pressure glue from directly ero...

Abstract

The invention provides a non-erosive flow-limiting valve used for sealing surface of a glue gun. The non-erosive flow-limiting valve comprises a valve seat and a valve element arranged in the valve seat and capable of moving back and force along the axis direction of the valve seat. The outer diameter of the valve element is smaller than the inner diameter of the valve seat and matches with the inner side wall on the inner portion of the valve seat to form a flow limiting tunnel to buffer the glue liquid. The non-erosive flow-limiting valve used for sealing surface of glue gun can limit and buffer high pressure glue liquid on the middle portion of the inner side via the flow limiting tunnel, can effectively prevent high pressure glue liquid from eroding the sealing surface of the valve directly during dispensing process, has good flow limiting function, can effectively prolong service life of the valve, and is simple in structure and convenient to process.

Description

Technical field [0001] The invention relates to an accessory for a glue application device, in particular to a flow limiting valve used for the sealing surface of a glue gun without erosion. Background technique [0002] The glue gun is an instrument used to spray or inject glue onto the surface of the adhered object under pressure. The glue gun in the prior art is controlled by a valve and the glue gun is manually operated. The valve core and valve seat are opened and closed to realize the glue out and stop glue from the glue gun. When the glue application is required, the valve core is moved to open the valve. When the valve is opened, the high-pressure glue flows into the nozzle of the glue gun through the valve. During the operation of the valve in the prior art (that is, the glue is discharged), the high-pressure glue directly erodes the valve seat and the sealing surface of the valve core, accelerating the wear of the valve and greatly shortening the life of the valve.
