Abstract
The utility model relates to the improvement structure of a kind of multifunctional integral valve filtering cavity gland, it is characterized in that: described filter screen gland comprises annular lid, the inner side surface of annular lid be integrally formed be inserted into filtering port in the cartridge part that is connected with filtering port, the excircle of cartridge part is provided with thread section, on the cartridge part, lower end of screw thread, is provided with the ring-shaped step for being set with tubular filter screen; The inside of cartridge part is provided with collection thing groove; On the exterior edge face of filter screen gland, be arranged with two pusher dogs, each pusher dog all has the outward edge of filter screen gland radially inwardly to arrange, and leaves gap between two pusher dogs.Technique scheme has operability more easily compared with existing gland, has facilitated operator's dismounting and installation, has saved operator and carry multiple types of tools in the time of maintenance, cleaning, thereby more can improve its operability; In addition, the utility model also have simple in structure, reasonable in design, be easy to processing, the advantage such as with low cost.
Description
Technical field
The utility model belongs to technical field of valve manufacturing, particularly relates to the architecture advances of a kind of multifunctional integral valve filtering cavity gland.
Background technique
Screw down nonreturn valve belongs to multifunction valve class, and it had both had the function of stop valve, and also with the function of safety check, screw down nonreturn valve is widely used in the current industry of each pipe at present simultaneously; But existing stop valve structure complexity, installation and maintenance inconvenience, and also the life-span is shorter, need to irregularly keep in repair or change.Cause the main cause of this kind of problem generally to have two kinds, a kind of is that product structure itself exists certain defect, for example sealing; In addition; screw down nonreturn valve above-mentioned contain impurity in the middle of medium time just often can be blocked; in the time containing larger impurity in medium, can cause valve internal component to wear and tear; thereby cause the leakage of valve; once the leakage that occurs to cause because of wearing and tearing certainly will will be carried out the replacing of valve, thereby causes the raising of maintenance cost.Structure for the gland that press-fits in the middle of prior art mainly comprises gland body, gland body is provided with assembling screw thread, the outer-hexagonal nut that the outer end of gland body is integrally formed with, in the time of locking or dismounting, need to operate by special spanner like this, need to configure the spanner of different model for the valve of different sizes, just can carry out field maintenance thereby maintenance man need to carry the instrument of various models, thereby cause inconvenience.
Summary of the invention
The utility model provides a kind of architecture advances of simple in structure, easy to operate, the multifunctional integral valve filtering cavity gland that improves maintenance operation efficiency for solving the technical problem existing in known technology.
The technological scheme that the utility model is taked for the technical problem existing in solution known technology is:
The architecture advances of filtering cavity gland for a kind of multifunctional integral valve, it is characterized in that: described filter screen gland comprises annular lid, the inner side surface of annular lid is integrally formed with the cartridge part being inserted in filtering port, the excircle of described cartridge part is provided with thread section, on the cartridge part, lower end of screw thread, is provided with the ring-shaped step for being set with tubular filter screen; The inside of described cartridge part is provided with collection thing groove, is arranged with two pusher dogs on the exterior edge face of described filter screen gland, and described each pusher dog all has the outward edge of filter screen gland radially inwardly to arrange, and leaves gap between two pusher dogs.
The utility model can also adopt following technical measures:
The lateral cross section of described pusher dog and or longitudinal cross-section be trapezium structure.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, there is operability more easily compared with existing gland, be used in the superiority that more can embody multifunction valve with the multifunctional integral valve of filtrating equipment, and this gland also has the function that stores impurity; In addition, the pusher dog that is arranged on gland exterior edge face replaces existing hexagon nut, has facilitated operator's dismounting and installation, has saved operator and carry multiple types of tools in the time of maintenance, cleaning, thereby more can improve its operability; In addition, the utility model also have simple in structure, reasonable in design, be easy to processing, the advantage such as with low cost.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the utility model uses phase diagram.
In figure: 1, annular lid; 1-1, cartridge part; 1-2, thread section; 1-3, ring-shaped step; 1-4, collection thing groove; 1-5, pusher dog; 2, shape filter screen.
Embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1 and Fig. 2, the architecture advances of filtering cavity gland for a kind of multifunctional integral valve, described filter screen gland comprises annular lid 1, the inner side surface of annular lid is integrally formed with the cartridge part 1-1 being inserted in filtering port, the excircle of described cartridge part is provided with thread section 1-2, is provided with the ring-shaped step 1-3 for being set with tubular filter screen 2 on the cartridge part, lower end of screw thread; The inside of described cartridge part is provided with collection thing groove 1-4, and said structure has been realized and the coordinating of above-mentioned anti-reverse-flow assembly, and has the impurity of storage function simultaneously.
In order to realize portable type dismounting, save and adopt outer allotment of labor's tool to dismantle, improve maintenance efficiency, on the exterior edge face of described filter screen gland 1-, be arranged with two pusher dog 1-5, described each pusher dog all has the outward edge of filter screen gland radially inwardly to arrange, and leaves gap between two pusher dogs.
In order to improve the intensity of above-mentioned pusher dog, the lateral cross section of described pusher dog and or longitudinal cross-section be trapezium structure.
Technique scheme has operability more easily compared with existing gland, is used in the superiority that more can embody multifunction valve with the multifunctional integral valve of filtrating equipment, and this gland also has the function that stores impurity; In addition, the pusher dog that is arranged on gland exterior edge face replaces existing hexagon nut, has facilitated operator's dismounting and installation, has saved operator and carry multiple types of tools in the time of maintenance, cleaning, thereby more can improve its operability; In addition, the utility model also have simple in structure, reasonable in design, be easy to processing, the advantage such as with low cost.
The above is only to preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, every foundation technical spirit of the present utility model is to any simple modification made for any of the above embodiments, equivalent variations and modification, all belong in the scope of technical solutions of the utility model.
