Abstract
The utility model relates to a filter mesh device for a mud density meter. The filter mesh device comprises a membrane seat, a safety cover and a mesh, wherein one end of the safety cover is fixed with the membrane seat, and the other end of the safety cover is welded and fixed with the mesh. The filter mesh device has the benefits that after structural design and modification, the existing filter mesh structure can completely replace the original giant mesh structure, thereby overcoming the defects of large volume, difficulty in movement, difficulty in disassembly and assembly, and the like; the filter mesh is separated from the membrane seat, the application is simple and flexible, and the free selection can be performed according to whether a measured medium has large impurities or not; and in the aspect of connection process, the safety cover and the membrane seat are connected through a clamp, the mounting and the detachment are simple and quick, and the filter mesh device is convenient to detach and clean. The mesh and the safety cover adopt the full-welding technology and are connected without threads or a seal ring, and the performance is more reliable.
Description
Technical field
The utility model relates to a kind of filter screen device that is used for mud scale, is widely used in the fast assembling-disassembling measure field.Be applicable in oil exploration and the well logging and forecast leakage, blowout, and judge anomaly and other high temperature of down-hole slurry density, process fluid and the pipeline of most dangerous industrial sites and the density measure of interior working fluid of pipe and static liquid that hygienic requirements is arranged or gather easily and condense.
Background technology
Mud scale need move at any time according to field conditions when detecting, and for on-fixed is installed, and need be placed in the mud for a long time, if assembled high concentration of sediment around the diaphragm, will influence accuracy of measurement.Be the cleaning around the protection diaphragm at present, a huge net is covered in domestic employing around the film seat.Though can prevent that like this silt from entering, volume is excessive, too heavy, for require to satisfy can move at any time very inconvenient, and if silt in a single day enter, cleaning is also very inconvenient.In addition, in-site measurement mixed liquor cognition impacts measuring diaphragm.
Summary of the invention
In view of the problem that prior art exists, the utility model provides a kind of filter screen device that is used for mud scale.This device can protect diaphragm normally to measure, and overall volume is little, can conveniently install, dismantle easily, can also be durable in use.
The utility model for achieving the above object, the technical scheme of being taked is: a kind of filter screen device that is used for mud scale, it is characterized in that: comprise film seat, safety guard, screen pack, described safety guard one end and film seat are fixed, and the safety guard other end and screen pack welding are fixing.
The beneficial effects of the utility model are: through the structural design and the transformation of the way, present filter screen structure has replaced the structure of an original huge net fully, it is big to have overcome volume, be difficult for moving, shortcoming such as not easy to assemble, screen pack and film seat are separated, on using, whether simple and flexible can have bulk impurity freely to select according to measured medium; On process connected, safety guard adopted clamping hoop type to be connected with the film seat, and installation dismounting mode is simply quick, convenient for dismounting and washing.Screen pack and safety guard adopt full solder technology, do not have the connection of screw thread or sealing ring, more reliable performance.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a vertical view of the present utility model.
The specific embodiment
As shown in Figure 1, be used for the filter screen device of mud scale, comprise film seat 1, safety guard 2, screen pack 3.Film seat 1 bottom is cylinder 1-1, and the upper end is the round entity 1-3 that has a circle inclined-plane 1-2.Safety guard 2 is a tubulose, is provided with the boss 2-2 of an astragal inclined-plane 2-1 in safety guard 2 lower ends, and safety guard 2 inwall upper port are provided with a circle right angle mouth 2-3, are arranged with four oval through hole 2-4 on the cylindrical wall of safety guard 2.Screen pack 3 is a round sheet, is provided with a center hole 3-1 on the circular face of screen pack 3, and stretching out along center hole 3-1 is provided with eight circular hole 3-2 of first lap successively, 12 circular hole 3-3 of second circle.
One end of safety guard 2 is placed on the face of round entity 1-3 of film seat 1, block the inclined-plane 2-1 of safety guard 2 and the inclined-plane 1-2 of film seat 1 with clip, be fixed together, screen pack 3 is placed among the right angle mouth 2-3 that safety guard 2 other ends are provided with, adopt argon arc welding that it is welded together, 21 holes in screen pack 3 can stop the big grain silt contact diaphragm in the measuring process, cause the run-down of measuring diaphragm, damage densitometer.4 oval through hole 2-4 around safety guard 2 can make the granule silt that enters in the measuring process in the screen pack leak out from perforate, prevent that silt is detained near diaphragm for a long time, damage diaphragm or influence accuracy of measurement.
