Technical Field
The utility model belongs to the technical field of the flush coater, in particular to discharge valve structure for high-pressure airless flush coater.
Background
The high-pressure airless sprayer discharges air in the high-pressure sprayer or high-pressure liquid gathered in the high-pressure sprayer by using the high-pressure discharge valve, so that no air is mixed in the high-pressure airless sprayer, and the normal operation of the sprayer is ensured. The existing high-pressure airless sprayer adopts a traditional quick-opening ball valve as a high-pressure discharge valve. The opening and closing part of the ball valve is a sphere which moves along the axis of the centering seat, thereby achieving the purpose of opening and closing the passage. Ball valves are used primarily for opening and closing pipes and equipment media. The existing discharge valve has poor centering effect, can cause the ball to hit the alloy surface at the edge, and is not sealed for a long time, if only centering is carried out, the discharge hole can be reduced, and the discharge flow is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a high pressure airless sprayer is with discharge valve structure solves current discharge valve centering effect not good, can lead to the spheroid to hit the limit alloy face, and the time length leads to unsealed, if only do the centering, the discharge gate will reduce, influences discharge flow's problem.
The utility model adopts the following technical scheme:
a discharge valve structure for a high-pressure airless sprayer comprises a valve body, wherein a feed inlet is formed in the bottom end of the valve body, a discharge outlet is formed in the side wall of the valve body, a cavity is formed in the valve body, the bottom end of the cavity is communicated with the feed inlet, the side wall of the cavity is communicated with the discharge outlet, a material guide pipe is inserted into the bottom end of the cavity, a centering seat is connected to the top of the material guide pipe, a jacking screw is abutted to the top of the centering seat and is in threaded connection with the top of the cavity, a counter bore is formed in the bottom end of the centering seat, a support seat is arranged in the counter bore and is matched with the counter bore, a triangular centering hole is formed in the top of the counter bore, the cross section of the triangular centering hole is in a regular triangle shape, guide holes are formed between three corners of the triangular centering hole and the side wall of the centering seat respectively, the bottom of the ball body is abutted to the through hole, the top of the ball body is abutted to a spring, and the top of the spring is abutted to the bottom of the tightening screw rod.
Furthermore, a polymer nylon sealing ring is arranged between the bottom end of the tightening screw rod and the cavity.
Furthermore, a sealing gasket is arranged between the supporting seat and the material guide pipe.
Furthermore, three corners of the triangular centering hole are arc-shaped respectively, so that the wall thickness between the centering seat and each corner of the triangular centering hole is increased, and the mechanical strength of the centering seat is ensured.
Furthermore, the ball body is a reinforced ceramic ball and is not easy to wear.
The utility model has the advantages that: this high pressure airless sprayer goes out valve structure, simple structure, the load is big, long service life, triangle centering hole structure makes and strengthens ceramic ball and can keep the concentricity in going out the valve case to beat, makes ceramic ball and bottom alloy seat sealing performance better, and striking alloy seat sealing surface's outer seal mouth when avoiding ceramic ball to beat leads to sealed face to damage, utilizes triangle-shaped's triangle to carry out the ejection of compact, does not influence ejection of compact flow, can increase the load.
