Abstract
The utility model discloses a low-noise reciprocating plunger pump which can reduce noise and prolong service life, and the valve body of which is provided with buffering structure. The low-nose reciprocating plunger pump comprises a pump body (1), a lower valve base (2), a valve (3), an upper valve base (4) and a plunger (5), with a buffering cushion (31) made of flexible materials being equipped on the upper part of the sealing-cone-oil-line of said valve (3). The low-noise reciprocating plunger pump adopting the valve provided with buffering structure can effectively reduce noise and prolong service life of the valve base and the valve.
Description
Technical field the utility model relates to a kind of plunger pump of carrying liquid, particularly a kind of low noise reciprocating pump.
The valve seat and the valve of the existing reciprocating stroke plunger pump of background technique all are to make with the pure metal material, and in the running of pump, very big noise is sent in valve and valve seat direct collision, and particularly under high speed, high pressure situation, reciprocal time increases, and noise is bigger; Rigidity is back and forth collided for a long time simultaneously, and is bigger to the damage of valve seat and valve, the working life of having reduced valve seat and valve.
Summary of the invention purpose of the present invention is exactly at the deficiencies in the prior art, the low noise reciprocating pump that provides a kind of valve body or valve seat to have buffer structure, can reduce noise, increase the service life.
The technical solution of the utility model is as follows: a kind of low noise reciprocating pump, comprise the pump housing, valve seat, valve and plunger, and the sealing cone potted line top of described valve seat and valve is provided with the cushion pad of being made by flexible material.This cushion pad plays buffer function when valve seat is contacted with valve seat, flexible collision is changed in original rigidity collision.
One depression is arranged at the bottom of described cushion pad, is buckled on the protruding column that valve cone face seal line top adapts with it, and the tapering of its bottom, outer conical surface is consistent with the tapering of the valve seal conical surface; The bolt of valve central upper portion setting passes the cushion pad center hole, and the screw that is provided with the pressing plate center matches, and cushion pad is pressed in therebetween.Adopt this structure, both kept the basic shape of former valve, it is as a whole that cushion pad and valve are organically combined, and can effectively play buffer function, is convenient to maintenance again and changes parts.
Described cushion pad is to be connected in the annulus groove perpendicular to valve axis that valve cone face seal line top processed.
Described cushion pad is to be connected in the annulus groove perpendicular to valve axis that valve seat conical surface seal line top processed.
Described cushion pad is to be made by rubber material.Can select corresponding rubber material according to the character of conveying liquid, with the requirement of the corrosion resistance that guarantees cushion pad, the working life of improving cushion pad.
A kind of low noise reciprocating pump of the present utility model adopts valve or valve seat with buffer structure, can effectively reduce the working life of noise, prolongation valve seat and valve.
