Abstract
The utility model relates to an improved booster pump valve sleeve, pure titanium flanges connected with an extension cylinder head and a pump seat are welded to the upper and lower ends of the valve sleeve made of pure titanium tube; the utility model has the advantages of rather excellent air tightness, acid resistance, corrosion resistance, long service life, reduced maintenance times and cost, convenient dismounting, and effectively reduced maintenance cost.
Description
Technical field:
The utility model belongs to the autoclave pressurized equipment, specifically is a kind of improved compression pump valve pocket.
Background technique:
The compression pump valve pocket that uses for the autoclave ore pulp belongs to the titanium alloy material at present, under acid condition, use for a long time, acid is to the valve pocket seriously corroded, valve pocket and the cylinder cap joint is as easy as rolling off a log is corroded particularly, the working life of valve pocket is shorter, the general use must be changed in 2-3 month, because repair and replacement are frequent, the equipment that influences runs well, and has increased cost, therefore, improvement to the compression pump valve pocket, strengthen compression pump valve pocket acid resistance, extend working time, reduce an urgent demand that user cost is to use producer.
The model utility content:
The purpose of this utility model provides a kind of improved compression pump valve pocket, and it helps extending working time, and reduces repair and replacement number of times and user cost.
The purpose of this utility model is achieved through the following technical solutions:
A kind of improved compression pump valve pocket is characterized in that: the valve pocket upper and lower end that pure titanium material titanium pipe is made is welded with the pure titanium material flange plate that links with external cylinder cap and pump seat respectively.
The flange plate of described valve pocket upper end is the structure of indent step.
The compression pump valve pocket that the utility model provides, the flange plate and the external cylinder cap contacting point of its two ends welding have better seal and acid resistance, and this valve pocket decay resistance is strong, long service life, reduce maintenance frequency and cost, easy accessibility can effectively reduce maintenance cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Each sequence number is among the figure: 1-has the flange plate of waterline, 2-valve pocket, 3-flange plate.
Embodiment
Describe below in conjunction with drawings and Examples.
As shown in the figure, compression pump valve pocket of the present utility model, valve pocket is made of pure titanium material titanium pipe, the valve pocket upper/lower terminal welds the flange plate that pure titanium material is made respectively, it is the structure of indent step that there is the flange plate of waterline the upper end, and this structure is a waterline, is connected with external cylinder cap, strengthened the sealing of valve pocket and cylinder cap contacting point, solved valve pocket and cylinder cap contacting point and the corrosion of leakage occurred cylinder cap because of sealing.The flange plate of lower end is connected with external pump seat.
Claims (2)
