Abstract
The utility model discloses a plunger valve of an airless sprayer, which includes a plunger valve body, a plunger rod, a regulating nut and a cylinder body, wherein a group of V-shaped seal rings are arranged between the plunger valve body and the cylinder body; a concave gasket and a convex gasket are arranged at two ends of the V-shaped seal rings respectively; the plunger valve body and the plunger rod are in threaded connection; a valve ball is arranged at the upper part of a valve port of the plunger valve body; a reset spring is arranged between the valve ball and the plunger rod; the regulating nut is arranged at the lower end of plunger rod; and a pressure reducing sleeve is arranged between the regulating nut and the convex gasket. The plunger valve is simple and compact in structure, the height of the plunger valve body is lowered, and the service life of the V-shaped seal rings is prolonged.
Description
Technical field
The utility model relates to a kind of parts of airless sprayer, and concrete is a kind of airless sprayer plunger valve.
Background technique
The plunger valve that adopts in existing spraying machine is at the plunger valve body locking nut to be set to adjust tightness between V-shaped seal ring and the cylinder body, and is bigger in the short transverse size, makes that spraying machine integral body is higher.In order to reduce the complete machine height of spraying machine, the convenience of construction is moved in increase, and the plunger valve that therefore need design a kind of compact structure satisfies user's requirement.
The model utility content
At above-mentioned deficiency of the prior art, the utility model aims to provide a kind of airless sprayer plunger valve, dexterously adjusting nut is arranged on the plunger rod, has successfully reduced the size of plunger valve height degree direction, has reduced the complete machine height of spraying machine.
To achieve these goals, the technical solution of the utility model: a kind of airless sprayer plunger valve, it comprises plunger valve body, plunger rod, adjusting nut and cylinder body, one group of V-shaped seal ring is set between described plunger valve body and the cylinder body, described V-shaped seal ring two ends arrange recessed pad and protruding pad respectively, and described plunger valve body adopts with plunger rod and is threaded.
Further, described plunger valve body valve port top arranges valve ball, between described valve ball and the plunger rod Returnning spring is set.
Further, described plunger rod lower end arranges adjusting nut.
Further, between described adjusting nut and the protruding pad pressure reducing sleeve is set.
The beneficial effects of the utility model: dexterously adjusting nut is arranged on the plunger rod, has reduced the height of plunger valve body, and between adjusting nut and protruding pad, be provided with pressure reducing sleeve, improved the working life of V-shaped seal ring.
