Technical field
The utility model is related to check-valves equipment technical field, specially a kind of fast loaded check valve of corrosion-resistant sanitation-grade.
Background technology
At present, check-valves is a kind of conventional valve installed for oil field water injection wellhead, and main purpose is to prevent water filling
Pressure is low, injection aqueous reflux in pit shaft when termination of pumping, causes bottom pressure excited, causes formation sand production etc..
But the existing fast loaded check valve of sanitation-grade has some shortcomings part in use, by check-valves institute
Conducting fluid all has or strong or weak corrosivity mostly, and check-valves its sealing after corroding for a long time will also subtract significantly
It is weak, liquid leakage is easily caused, so as to cause unnecessary wasting even to be likely to causing danger in the staff of other work
Danger.
Utility model content
The purpose of this utility model is to provide a kind of corrosion-resistant fast loaded check valve of sanitation-grade, to solve above-mentioned background technology
The check-valves conducting fluid of middle proposition has corrosivity mostly, and check-valves its sealing after corroding for a long time is poor, easily makes
The problems such as into liquid leakage.
To achieve the above object, the utility model provides following technical scheme：A kind of fast loaded check valve of corrosion-resistant sanitation-grade,
Including upper valve body and lower valve body, external interface is provided with the top of the upper valve body, the outermost of the upper valve body is provided with gold
Category layer, is provided with rubber layer on the inside of the metal level, and the bottom of rubber layer is provided with chimb, is set on the inside of the rubber layer
Ceramic layer is equipped with, the lower valve body is fixedly connected by retaining collar with upper valve body, the front side of the retaining collar is by welding
It is installed with and through hole is provided with catch, and catch, the installed in front of the retaining collar has on the outside of bolt, and bolt and sets
External screw thread is equipped with, one end of the bolt is installed with nut by external screw thread.
Preferably, the internal thread of the external screw thread of the bolt and nut cooperates.
Preferably, through hole is provided with two catch on the retaining collar, and two through holes are located at same straight line
On.
Preferably, the shape size all same of the upper valve body and lower valve body.
Compared with prior art, the beneficial effects of the utility model are：A kind of corrosion-resistant fast loaded check valve of sanitation-grade, it is first
First, on the basis of original, one layer of ceramic layer is internally provided with device, because the corrosion resistance of ceramics is extremely strong, thus can
Greatly to improve the service life of check-valves；Secondly, one layer of rubber layer is had additional in the middle of ceramic layer and metal level, by rubber
The isolation buffer effect of cortex, can well prevent outer metal layers to be hit and be directly conducted to inner side ceramic layer and cause
Ceramic layer fragmentation, so as to further improve the service life of check-valves；Finally, the bottom of rubber layer is provided with the middle of the check-valves
On the one hand chimb, the chimb can well ensure being brought into close contact for upper lower valve body, and the chimb of another aspect outer rim can ensure
Retaining collar holds upper lower valve body tighter.
