Abstract
The invention relates to a needle valve pad block structure of a needle valve spray nozzle. The needle valve pad block structure comprises a needle valve pad block, wherein the needle valve pad block is in a cylindrical groove structure, in addition, a through hole allowing a valve needle to pass is arranged in the center of the groove bottom of the groove type needle valve pad block, and material overflowing holes are arranged in the groove wall of the groove type needle valve pad block. The number of the material overflowing holes is four, and the four overflowing holes are uniformly distributed in the groove wall. The scheme effectively solves the problem that trace plastics driven out in the moving process of the valve needle cannot be discharged, so the continuous movement of the valve needle is influenced.
Description
Technical field
The invention belongs to the TOP-TIP field, relate to a kind of needle-valve cushion block structure of needle-valve nozzle.
Background technology
In the needle-valve nozzle commonly used, shown in Fig. 1 ~ 2, needle-valve cushion block 1 directly is connected with flow distribution plate 2; Said needle-valve cushion block 1 is the cylinder shape groove structure, and bottom land 7 centers of needle-valve cushion block 1 are provided with the via hole 3 that supplies the needle (not shown) to pass, and leaves the gap between needle and the flow distribution plate 2; Needle can be taken micro plastics out of in motion process; Overflow in the cavity 5 that between needle-valve cushion block 1 cell wall 6 and template 4, forms, after a period of time, will pile up a large amount of plastics of being taken out of by needle in this cavity 5.As shown in Figure 2, because the cell wall 6 of needle-valve cushion block 1 is a solid construction, these plastics of being piled up can't be discharged from, and are carbonized easily, can influence the motion of needle after the carbonization.Therefore, how addressing the above problem, is the content that the present invention will study.
Summary of the invention
The present invention provides a kind of needle-valve cushion block structure of needle-valve nozzle, its objective is that solving the micro plastics that needle takes out of in motion process can't discharge, and influence needle and continues the problem of moving.
For achieving the above object, the technical scheme that the present invention adopts is: a kind of needle-valve cushion block structure of needle-valve nozzle, comprise the needle-valve cushion block, and this needle-valve cushion block is the cylinder shape groove structure, and the bottom land center of this fluted body needle-valve cushion block is provided with the via hole that supplies needle to pass; The cell wall of said fluted body needle-valve cushion block is provided with the flash hole.
Related content in the technique scheme is explained as follows:
1, in the such scheme, said flash hole is a plurality of, along circumferentially being distributed on the said cell wall.
2, in the such scheme, said flash hole is four, along circumferentially being distributed on the said cell wall.
Because the utilization of present technique scheme, the present invention compared with prior art has advantage:
1, the present invention is owing to offer the flash hole on the cell wall of needle-valve cushion block; The plastics that make needle when motion, take out of can be discharged through this flash hole; In order to avoid in the cavity that bulk deposition forms between needle-valve cushion block and template; Prevent the plastics carbonization, thereby solved that needle is taken the bulk deposition of plastics, carbonization out of and the problem of moving and being obstructed.
2, the present invention is simple in structure, practical.
Description of drawings
Accompanying drawing 1 is needle-valve cushion block and flow distribution plate and a template group assembling structure sketch map in the prior art;
Accompanying drawing 2 is the plan structure sketch map of needle-valve cushion block in the prior art;
Accompanying drawing 3 is needle-valve cushion block master TV structure sketch map of the present invention;
Accompanying drawing 4 is needle-valve cushion block plan structure sketch map of the present invention;
Accompanying drawing 5 is needle-valve cushion block of the present invention and flow distribution plate and template group assembling structure sketch map.
In the above accompanying drawing: 1, needle-valve cushion block; 2, flow distribution plate; 3, via hole; 4, template; 5, cavity; 6, cell wall; 7, bottom land; 8, flash hole.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described:
Embodiment:
Shown in Fig. 3 ~ 5, a kind of needle-valve cushion block structure of needle-valve nozzle comprises needle-valve cushion block 1, and this needle-valve cushion block 1 is the cylinder shape groove structure, and bottom land 7 centers of this fluted body needle-valve cushion block 1 are provided with the via hole 3 that supplies needle to pass; The cell wall 6 of said fluted body needle-valve cushion block 1 is provided with flash hole 8.
Said flash hole 8 is a plurality of, along circumferentially being distributed on the said cell wall 6.
The said flash of this programme hole 8 is four, along circumferentially being distributed on the said cell wall 6.Owing on the cell wall 6 of needle-valve cushion block 1, offer flash hole 8; The plastics that make needle when motion, take out of can be discharged through this flash hole 8; In order to avoid in the cavity 5 that bulk deposition forms between needle-valve cushion block 1 and template 4; Prevent the plastics carbonization, thereby effectively solved needle because of the plastics bulk deposition of taking out of, the problem that the carbonization campaign is obstructed.
The foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to let the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
