Abstract
The utility model discloses a plunger pole sealing device for a spraying machine, which comprises pump bases, gland nuts, plunger poles and wet cups, wherein a group of V-shaped seal rings are arranged between each pump base and the corresponding plunger pole; a concave pad and a convex pad are arranged at two ends of each group of V-shaped seal rings; a relief sleeve, a gasket and a spring are arranged below each convex pad; each gland nut is arranged above each concave pad; a bushing is arranged between each gland nut and the corresponding plunger pole; and each wet cup is arranged at the upper end of the corresponding gland nut, and filled with a seal liquid. The plunger pole sealing device for the spraying machine can prevent the part contacted with paint, on each plunger pole from being contacted with the air during upward operation, and the service lives of the V-shaped seal rings and the plunger poles are improved.
Description
Technical field
The utility model relates to a kind of parts of pneumatic airless sprayer, is specifically related to a kind of spraying machine plunger rod seal arrangement.
Background technique
The plunger rod seal arrangement that adopts in existing spraying machine comprises plunger rod, pump seat, spring, protruding pad, V-shaped seal ring, recessed pad and gland nut.When V-shaped seal ring has loosening or mild wear, just having a small amount of coating to be moved upward by plunger rod brings out, along with the development and change of coating, having now behind many coating ingresss of air can very fast curing, is attached on the plunger rod, will the scratch V-shaped seal ring when plunger rod moves downward, the coating that brings out when plunger rod moves upward is just more, so goes down, and V-shaped seal ring will soon be pulled loses seal action, as untimely replacing, also can pull plunger rod and cause bigger loss.Wet cup is also arranged in the sealing configuration that has, but insufficient height does not have the effect that intercepts air.In order to prolong the working life of V-shaped seal ring, therefore need a kind of plunger rod seal arrangement more reliably of design to satisfy user's demand.
Summary of the invention
At above-mentioned deficiency of the prior art, the utility model proposes a kind of spraying machine plunger rod seal arrangement, by pressure reducing sleeve being set before V-shaped seal ring and utilizing ingress of air when filling sealing fluid in the wet cup and preventing from the plunger rod up moving with the coating contact position, the working life of having improved V-shaped seal ring and plunger rod.
In order to achieve the above object, the technical solution of the utility model: a kind of spraying machine plunger rod seal arrangement comprises pump seat, gland nut, plunger rod and wet cup.One group of V-shaped seal ring that Open Side Down is set between described pump seat and the plunger rod, and described V-shaped seal ring two ends arrange recessed pad and protruding pad respectively.
Further, below the described protruding pad spring is set.
Further, between described protruding pad and the spring liner is set, between described liner and the plunger rod pressure reducing sleeve is set.
Further, above the described recessed pad gland nut is set, between described gland nut and the plunger rod lining is set.
Further, described wet glass is arranged at the gland nut upper end, fills sealing fluid in the described wet cup, the extreme higher position the when liquid level of sealing fluid up moves above the position that can contact coating on the plunger rod in the described wet cup.
The beneficial effects of the utility model are: the utility model has reduced the pressure when coating passes through V-shaped seal ring by pressure reducing sleeve was set before V-shaped seal ring, strengthened sealing effect.Utilize ingress of air when filling sealing fluid in the wet cup and preventing from the plunger rod up moving with the coating contact position, prevent from sticking to the paint solidification on the plunger rod, therefore the working life of having improved V-shaped seal ring and plunger rod.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the utility model embodiment's structural representation.
In the accompanying drawing, the 1-pump seat; The 2-spring; The 3-liner; The 4-pressure reducing sleeve; The protruding pad of 5-; 6,7-V RunddichtringO; The recessed pad of 8-; The 9-lining; The 10-gland nut; The wet cup of 11-; The 12-plunger rod; The 13-sealing fluid.
Embodiment
Further describe the utility model below in conjunction with specific embodiment and accompanying drawing.
A kind of a kind of spraying machine plunger rod seal arrangement as shown in Figure 1, comprise pump seat 1, gland nut 10, plunger rod 12 and wet cup 11, one group of V-shaped seal ring that Open Side Down 6,7 is set between described pump seat 1 and the plunger rod 12, and described V-shaped seal ring 6,7 two ends arrange recessed pad 8 and protruding pad 5 respectively.Below the described protruding pad 5 spring 2 is set.Between described protruding pad 5 and the spring 2 liner 3 is set, between described liner 3 and the plunger rod 12 pressure reducing sleeve 4 is set.Above the described recessed pad 8 gland nut 10 is set, between described gland nut 10 and the plunger rod 12 lining 9 is set.Described gland nut 10 upper ends arrange wet cup 11, fill sealing fluid 13 in the described wet cup 11, the extreme higher position the when liquid level of described sealing fluid 13 up moves above the position that can contact coating on the plunger rod 12.
The utility model has reduced the pressure when coating passes through V-shaped seal ring by pressure reducing sleeve was set before V-shaped seal ring, strengthened sealing effect.Have loosening along with V-shaped seal ring uses for a long time or mild wear is moved upward when bringing out by plunger rod as a small amount of coating, also be immersed in all the time in the sealing fluid and ingress of air not, prevented paint solidification, therefore the working life of having improved V-shaped seal ring and plunger rod.
More than technological scheme that the utility model embodiment is provided be described in detail, used specific case herein the utility model embodiment's principle and mode of execution are set forth, above embodiment's explanation only is applicable to the principle that helps to understand the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, the part that on embodiment and application area, all can change, in sum, this description should not be construed as restriction of the present utility model.
