Abstract
The utility model relates to a load reducing silencer for air compressors, which comprises a valve body which is provided with a hollow cavity. The lower end of the valve body is provided with a valve seat which is communicated with a cylinder cover of an air compressor. The valve body is provided with an interface which is communicated with a pressure adjusting valve of the air compressor. The inner of the valve body is provided with a valve core which can be moved along the valve body in a shaft direction. A filter core is arranged between a shell and the valve body. An air inlet hole of the valve body is arranged on the lower plane of a dummy club. The sealing surface of the valve core corresponds to an air mouth on the valve seat. A spring is arranged between the valve seat and the valve core. Due to the adoption of the mode of the air mouth of the valve seat of a sealing plane, the air compressor can work safely. Simultaneously, processing technics is simplified and manufacture cost is reduced.
Description
The utility model relates to air compressor accessory field, the air pressure adjustment parts that particularly a kind of air compressor off-loading is eliminated the noise.
At present, air compressor air pressure adjustment parts roughly have one-way valve, unloading mechanism, air-filtering and silencer.Because the function difference just independently is loaded on the air compressor separately separately.In order to reduce the trouble in the maintenance and to reduce production costs, Chinese patent discloses for No. 97235028.4 a kind of " air compressor off-loading noise elimination combination pressure regulator ".Its a plurality of parts with air compressor are combined into one.But because inlet hole is located at the sidewall of valve body, when air compressor air pressure reached rating value, pressure air entered the valve body upper end from joint, and spool is pressed down, and the inlet hole that will be located at body wall by the spool circumferential surface seals, and makes air can't enter air compressor cylinder.But air compressor in the course of the work, inevitably has dustiness particle and moisture, and dustiness particle and moisture are easy to enter valve body again.In above-mentioned patent, the inlet hole of body wall is sealed by the spool circumferential surface, after dustiness particle and moisture enter spool circumferential surface or valve interior surface, can cause spool to be blocked or get rusty (because of air compressor does not often use), air compressor off-loading noise elimination combination pressure regulator can not normally be sealed or open, have a strong impact on the work safety of air compressor.Moreover because the inlet hole of body wall is sealed by the spool circumferential surface, the manufacturing of sealing surface is more tired, the cost height.
In order to overcome above defective, the inventor has excelsior spirit in arms, in the mode of gas port on the planar surface encloses valve seat, improves the deficiency of above-mentioned patent with circumferential surface closed valve inlet hole, makes air compressor off-loading silencer work safety and reliability.Simplify production technology simultaneously, reduce manufacture cost.
The purpose of this utility model is: provide a kind of simple in structure, with multiple air compressor parts be combined into one, reliable operation and the low air compressor off-loading silencer of cost.
In order to reach the above purpose, the utility model is achieved through the following technical solutions:
A kind of air compressor off-loading silencer comprises the valve body that is provided with cavity, and valve body lower end is provided with the valve seat that communicates with the air compressor cylinder lid, and valve body is provided with the interface that communicates with the air compressor pressure regulator valve; Being provided with in the valve body can be along the axially movable spool of valve body, and valve body is provided with shell outward, is provided with filter core between shell and valve body; Valve block upper half is the cylindrical hollow boss, and the valve body inlet hole is located on the boss lower plane, the corresponding one-tenth boss of spool shape, and the sealing surface of spool is corresponding with the gas port on the valve seat, and can make valve body inlet hole turnover air, and valve seat and valve core chamber are provided with spring.
Described valve body boss lower plane is the some inlet holes of distribution evenly, and the gas port of valve body, spool, spring and valve seat all is positioned on the same axis, is provided with heat insulating mattress between valve seat and shell.
Advantage of the present utility model is: owing to adopt the mode of planar surface encloses valve seat gas port, when having avoided dustiness particle and moisture to enter spool outer surface or valve interior surface, cause spool to be blocked and body cavity and valve core chamber get rusty; Air compressor off-loading silencer can not normally be sealed or open.Thereby, make air compressor work safety and reliability.Simplify processing technology simultaneously, reduced manufacture cost.Because be provided with filter core between shell and valve body, filter core not only has filtering function, but also has the effect of noise elimination.
Be elaborated the utility model in order more clearly to illustrate below in conjunction with accompanying drawing:
Fig. 1 is the schematic representation of the utility model air compressor off-loading silencer.
Fig. 2 is a valve body schematic representation of the present utility model.
As Fig. 1, shown in Figure 2, air compressor off-loading silencer, comprise the valve body 1 that is provided with cavity, valve body lower end is provided with the valve seat 2 that communicates with the air compressor cylinder lid, valve body is provided with the interface 3 that communicates with the air compressor pressure regulator valve, being provided with in the valve body can be along the axially movable spool 4 of valve body, valve body is provided with shell 5 outward, be provided with filter core 6 between shell and valve body, valve block upper half is a cylindrical hollow boss shape, and valve body inlet hole 8 is located on the boss lower plane, spool 4 corresponding one-tenth boss shapes, the sealing surface of spool is corresponding with the gas port on the valve seat 12, and can make the inlet hole 8 turnover air of valve body, and valve seat and valve core chamber are provided with spring 9.The gas port of valve body, spool, spring and valve seat all is positioned on the same axis, is provided with heat insulating mattress 10 between valve seat and shell.Shell is provided with some vents 11.
Working procedure of the present utility model is as follows: during air compressor work, air enters air compressor off-loading silencer from housing breather 11, filters to eliminate the noise through filter core 6 to enter valve body from valve body inlet hole 8, and sucks air compressor cylinder by valve seat gas port 12.When reaching rated pressure in the air compressor air storage tank, the air compressor pressure regulator valve is opened, pressure air enters valve body upper end cavity 7 from the interface 3 that communicates with pressure regulator valve, spool 4 is pressed down, gas port 12 on the lower surface closed valve seat of spool 4, make air can't enter air compressor cylinder, thereby reach the off-loading purpose.
