Embodiment

[0030] refer to figure 1 , a pneumatic high-pressure valve, including a top cover 1, an intermediate cavity 11, a fluid cavity 13, a dispensing seat 15, and a needle adapter 151 that are sequentially bolted in the vertical direction, the intermediate cavity 11, the fluid cavity 13 There is a fluid chamber 12 for the flow of the glue liquid between them, a dispensing chamber 14 is provided between the dispensing seat 15 and the needle adapter 151, a flow channel 121 is provided between the dispensing chamber 14 and the fluid chamber 12, and the middle chamber A striker 16 is slidably worn on the body 11. The striker 16 coincides with the axis of the flow channel 121 and passes through the flow channel 121. The striker 16 passes through one end of the flow channel 121 and is inserted into the glue dispensing chamber 14.

[0031] refer to figure 1 with figure 2 , including a sealing sleeve 17 sleeved on the striker 16, a groove 2 is opened on the side wall of the flow channel ...

Abstract

The invention discloses a sealing structure of a pneumatic high-pressure valve. The sealing structure comprises a sealing sleeve arranged on a firing pin in a sleeving manner, a groove is formed in the side wall of a flow channel and is an annular groove, a sealing ring is embedded in the groove, and the flow channel abuts against the sealing sleeve through the sealing ring. When the pneumatic high-pressure valve is used, only the sealing ring or the sealing sleeve needs to be replaced, good sealing performance of the pneumatic high-pressure valve can be kept, it is guaranteed that the pneumatic high-pressure valve can normally control flowing of a glue solution, and the effect of reducing the maintenance cost of the pneumatic high-pressure valve is achieved.

Description

technical field [0001] The present application relates to the technical field of pneumatic high-pressure valves, in particular to a sealing structure of pneumatic high-pressure valves. Background technique [0002] Pneumatic high-pressure valve belongs to a kind of dispensing valve, which is a kind of process equipment widely used in the field of product production. Its application scope covers product bonding, potting, coating, sealing, filling, dripping, scribing glue, etc. craft. [0003] The pneumatic high-pressure valve is connected with the glue storage tank that stores glue, pressurizes the inside of the glue storage tank, and the glue can enter the pneumatic high-pressure valve. The pneumatic high-pressure valve includes an intermediate cavity, a fluid cavity, a dispensing seat and a needle adapter connected in sequence. There is a fluid cavity between the intermediate cavity and the fluid cavity, and a glue drop is provided between the dispensing seat and the needl...
