Abstract
The utility model discloses and a kind of wafer type essence microdiaphragm pump check valve, it includes：Valve body, valve body include upper valve body and lower valve body, and the upper valve body includes valve deck and guide rod, guide rod is located at the lower part of valve deck, is set with flap on guide rod and spring, spring are located at flap and valve cover chamber, the sealing surface coordinated with flap is equipped with lower valve body, is to seal firmly between lower valve body and flap.It is light-weight, simple in structure, easy to process, and particle washes away in resistance to pumped (conveying) medium, and service life is longer.
Description
Technical field
It the utility model is related to a kind of valve, more particularly to a kind of wafer type essence microdiaphragm pump check valve.
Background technology
It is the heart equipment in whole production technology currently used for the diaphragm pump of alumina leaching technique.It is a kind of double
The double-acting piston pump of cylinder, the whole series pump be made ofs 4 pistons, 8 membranes, and each membrane, which is imported and exported, respectively a check valve, and totally 16
A check valve.16 diaphragm pump one-way valves must all normal stabilizations that just can guarantee that system, therefore diaphragm pump one-way valve is run
Quality play the role of in digestion series it is vital.
Since diaphragm pump institute feed slurry contains slurry particle, and diaphragm pump moves back and forth frequently, up to 34 times per minute,
One-way valve flap is caused to move back and forth frequent, therefore, medium is very big to washing away for diaphragm pump one-way valve, causes valve seat to be ground with flap
Damage is very fast, even if maintenance reuses, MaLS also only has 40-50 days.Frequent replace of diaphragm pump one-way valve also result in
Equipment greatly wastes.
Utility model content
The purpose of this utility model is to provide a kind of wafer type essence microdiaphragm pump check valve, to overcome currently available technology
Above shortcomings, it is resistant to washing away for pumped (conveying) medium, and service life is longer.
The purpose of this utility model is realized by following structure, it includes：Valve body, valve body include upper valve body with
Valve body, the upper valve body include valve deck and guide rod, and guide rod is located at the lower part of valve deck, flap and spring, spring position are set with guide rod
It is to seal firmly between lower valve body and flap in being equipped with the sealing surface with flap cooperation in flap and valve cover chamber, lower valve body.
The guide rod is hollow guide rod.
The valve body is cylinder.
The flap surface progress Nitrizing Treatment, and pile-up welding hard alloy on the sealing surface of lower valve body.
Sealing ring is equipped between the valve deck and lower valve body.
The flap end of the valve body is the arrival end of medium.
The utility model is by the flap of mutual cooperation, lower valve body and hard sealing, and particle washes away in resistance to pumped (conveying) medium,
The service life of valve is effectively extended, service life was average more than 90 days.Secondly, the utility model is connected to folder pump disengaging
Between mouth flange and pipe flange, not flanged on valve body, light-weight, simple in structure, easy to process, weight only accounts for original valve
/ 3rd of weight.Thirdly, be integrated without independent valve seat, valve seat and lower valve body, the sealing surface in lower valve body is direct
Heap is welded in lower valve body.
Brief description of the drawings
Fig. 1 is that figure is cutd open in the structural representation of the utility model, and Fig. 2 is that the use state of the utility model cuts open figure.
Embodiment
The embodiment of the utility model as shown in Figure 1 includes：Shape is the valve body of cylinder, and valve body includes upper valve body with
Valve body 4, the upper valve body include valve deck 5 and guide rod 2, and guide rod 2 is located at the lower part of valve deck 5, flap 1 and spring are set with guide rod 2
3, spring 3 is provided with deflector hole between flap 1 and valve deck 5 on valve deck 5, spring 3 makes flap 14 reciprocatingly slide along guide rod 2.Lower valve
The sealing surface coordinated with flap 1 is equipped with body 4, is to seal firmly between lower valve body 4 and flap 1.The guide rod 2 is hollow guide rod, can
The medium of transmission is set to enter the inner side of flap 1.1 surface of the flap progress Nitrizing Treatment, and heap on the sealing surface of lower valve body 4
Weld hard alloy.Sealing ring 6 is equipped between the valve deck 5 and lower valve body 4.The flap end of the valve body is the arrival end of medium.
The utility model as shown in Figure 2 is connected to folder between pump inlet and outlet flange and pipe flange.When transmission medium just
To during flowing, slurry overcomes the elastic force of spring 3 by the effect of pressure medium, and flap 1 is open-top and rearward moved along guide rod 2
It is dynamic, depart from flap 1 and the sealing surface of lower valve body 4, transmission medium flows to valve chamber by sealing surface, then flows to rear by valve chamber
Pipeline, conversely, when transmission medium flows back, the elastic force of spring 3 and the active force collective effect of medium press flap 1 on flap 1
On the sealing surface of lower valve body 4, play the role of sealing and avoid medium from flowing backwards.
To the described above of disclosed embodiment, those skilled in the art are enable to realize or use this reality
With new, a variety of modifications to present embodiment are it will be apparent that defined herein one to those skilled in the art
As principle can realize in other embodiments without departing from the spirit or scope of the present utility model.Therefore, it is all
Be with the same or similar technical solution of present embodiment, all fall within the scope of protection of the utility model.
