Resorption type valve for coating gun of the present utility model, at least comprise valve seat and spool, described spool is provided with the liquid chunnel of at least one entrance point that makes coating gun body and outlet end connection, described spool is coaxially arranged in described valve seat and spool is piston type with valve seat and coordinates, and described spool can move described liquid chunnel is closed along the opposite direction of liquid flow path direction.
Further, described spool is column structure, and the kidney slot that the front end sidewall that described liquid chunnel is described spool radially sinks to forming and the length direction of liquid chunnel and the axial direction of spool are consistent.
Further, the sidewall of described kidney slot and bottom connection place seamlessly transit formation globoidal structure, and the relative two side of the length direction of described kidney slot is obliquely installed and makes the opening size of described kidney slot to be increased gradually to upper end open place by bottom.
Further, described liquid chunnel is three and is evenly arranged along the circumferencial direction of described spool.
Further, the front end side wall of described valve seat is provided with and makes the inside and outside through hole being communicated with of valve seat.
Further, described valve seat is fixedly installed on coating gun body in the mode embedding, and the end, rear end of described valve seat is provided with the bounding means for valve seat being carried out to axial limiting.
Further, described valve seat rear inside is fixedly installed the seal ring that is coaxially coated at spool.
Further, described bounding means is nut.
The beneficial effects of the utility model: the resorption type valve for coating gun of the present utility model, the glue remaining in after rifle in glue passage flows out or water clock goes out coating gun mouth closing can to prevent coating gun, thereby avoids part to pollute and the waste of material; The structure of greatly having simplified resorption type valve, effectively reduces difficulty of processing, thereby effectively improves and manufacture efficiency and reduce costs, and is easy to promote.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is structural representation of the present utility model.
Embodiment
Fig. 1 is structural representation of the present utility model, as shown in the figure, resorption type valve for coating gun of the present utility model, at least comprise valve seat 5 and spool 7, described spool 7 is provided with the liquid chunnel that at least one entrance point 2 that makes coating gun body 1 and outlet end 9 are communicated with, described spool 7 is coaxially arranged in described valve seat 5 and spool 5 is piston type with valve seat 7 and coordinates, and described spool 7 can move described liquid chunnel is closed along the opposite direction of liquid flow path direction, resorption type valve for coating gun of the present utility model, can prevent that glue outflow or water clock that coating gun remains in glue passage after the rifle of pass from going out coating gun mouth, thereby avoid part to pollute and the waste of material, the structure of greatly having simplified resorption type valve, effectively reduces difficulty of processing, thereby effectively improves and manufacture efficiency and reduce costs, and is easy to promote.
In the present embodiment, described spool 7 is column structure, described liquid chunnel is that the front end sidewall of described spool 7 kidney slot 4 and the length direction of liquid chunnel that radially sink to forming are consistent with the axial direction of spool 7, adopt this structure, by kidney slot, the entrance point of described coating gun body and outlet end are communicated with, make glue can flow out smoothly and carry out gluing, when closing rifle, spool is moved backward, the outer surface of the front end of spool and the internal surface of valve seat are in conjunction with forming sealing, and make the outlet end place of coating gun body produce negative pressure, glue is sucked and rest on the inside of coating gun body, prevent that glue from flowing out, thereby prevent from part to pollute and the waste of material, in the time of needs gluing, spool is travelled forward, thereby the entrance point of coating gun body and outlet end are communicated with.
In the present embodiment, the sidewall of described kidney slot 4 and bottom connection place seamlessly transit formation globoidal structure, and the two side that the length direction of described kidney slot 4 is relative is obliquely installed and makes the opening size of described kidney slot 4 to be increased gradually to upper end open place by bottom, because the mobility of glue is poor, by this structure, what can make glue flows through liquid chunnel smoothly, can not produce glue and be detained the stifled glue phenomenon causing, and adopt this structure, can also simplified structure, improve and manufacture efficiency, reduce manufacture cost.
In the present embodiment, described liquid chunnel is three and is evenly arranged along the circumferencial direction of described spool 7, by this structure, even if spool rotates in movement process, still ensures that glue flows out coating gun body smoothly, can not impact using.
In the present embodiment, the front end side wall of described valve seat 5 is provided with and makes the inside and outside through hole 3 being communicated with of valve seat 5, this structure, and the entrance point that is beneficial to liquid chunnel and coating gun body is communicated with, easy to use.
In the present embodiment, described valve seat 5 is fixedly installed on coating gun body 1 in the mode embedding, the end, rear end of described valve seat 5 is provided with the bounding means 8 for valve seat 5 being carried out to axial limiting, described bounding means 8 is nut, and described nut is outer surface machining screw and is fixedly connected with coating gun body, can play good position-limiting action to valve seat and seal ring.
In the present embodiment, described valve seat 5 rear inside are fixedly installed the seal ring 6 that is coaxially coated at spool, and described seal ring 6 is undertaken spacing by bounding means; By the effect of seal ring, can carry out good sealing to the rear end of valve seat, and the inner negative pressure that produces of the outlet end that makes coating gun body in the time that spool moves backward, avoid the negative pressure space gas leakage causing because the sealability of valve seat inside is bad, ensure that glue can not flow out coating gun body by the glue at the outlet end place of coating gun body in the time closing rifle.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
