Abstract
The utility model belongs to a filtering device of liquid in a filtering pipeline and particularly relates to a filtering device capable of back washing. A T-shaped tee valve is installed at one side of a main pipeline, a first tee joint is installed on the main pipeline at the other side of the main pipeline, a first valve is installed on an outlet pipe of the main pipeline connected with the first tee joint, the outlet of the filtering device provided with a cask-shaped filter element is connected with the other interface of the first tee joint through a branch pipeline, the inlet of the filtering device is connected with a second tee joint through a branch pipeline, an interface of the second tee joint is connected with the other interface of the T-shaped tee valve, and a second valve is installed on the outlet branch pipeline connected with the other interface of the second tee joint. The filtering device provided by the utility model is reasonable in structure, convenient to operate and maintain and capable of not only filtering the fluid in the pipeline, but also back washing the filter element.
Description
Technical field
The utility model belongs to the filter of liquid in the filter pipe, but a kind of back-flushing filtering device particularly.
Background technology
Fluid in the pipeline in the process of circulation of downstream, still can produce impurity such as rust dirt after upstream master station filters, need local filter be installed at the downstream key position.
There are the following problems for existing filter:
1, owing to flow passage structure and filer element strength restriction, can not backwash.
2, multiple functional filter, volume is big, complex structure, by-pass valve control is various, manufacturing cost height, operation and maintenance inconvenience.
3, filter core out-of-shape is changed inconvenient.
Summary of the invention
But the purpose of this utility model is to provide a kind of back-flushing filtering device, and it is rational in infrastructure, not only can filter the fluid in the pipeline, and can carry out backwash to filter core, operation, easy to maintenance.
But the purpose of this utility model is achieved in that a kind of back-flushing filtering device, side on trunk line is installed with T type triple valve, on the trunk line of opposite side the one 3 pass joint is installed, the trunk line outlet that connects at the one 3 pass joint is installed with first valve, its outlet of filter with barrel-shaped filter core is connecting another interface of the one 3 pass joint by branch pipe(tube), the import of filter is connecting the 23 pass joint by branch pipe(tube), an interface of the 23 pass joint is connecting another interface of T type triple valve by branch pipe(tube), on the outlet stool road that another interface of the 23 pass joint connects second valve is installed.
When utilizing the utility model to carry out filter pipeline liquid, close trunk line by T type triple valve, open branch pipe(tube), open first valve of installing on the trunk line outlet, close second valve in the branch pipe(tube) outlet, liquid enters filter by the 23 pass joint, and filtered liquid enters trunk line by the one 3 pass joint.In the time need carrying out backwash to the barrel-shaped filter core of filter, close bye-pass by T type triple valve, open main line, close first valve in the trunk line import, open second valve on the branch pipe(tube), liquid in the trunk line enters in the filter from the outlet of filter barrel-shaped filter core is carried out backwash, and second valve of the liquid of backwash on branch pipe(tube) discharged from outlet.
The utility model simple structure, inside and outside bilayer is reinforced, and can hold the filter core of crossing of external and internal pressure; Cross filter core and adopt pressure cap to compress from a side seal, easy to loading and unloading; Adopt T type triple valve, in conjunction with the closed-loop path, simplify the operation, simplify the filter core manufacture craft, guarantee the intensity of filter core simultaneously; The loading and unloading filter core only need be opened the side pressure cap, saves the work of dismounting screw or degree of tightness gas thread, can change filtering accuracy fast, installs, safeguards more convenient.Utilize T type valve, once-through operation can be controlled three ports simultaneously, realizes liquid filtering or filter core is carried out backwash.Both saved valve, reduced the hidden danger tie point in the installation process again, installed, operated directly perceived succinct; In conjunction with the closed-loop path, increase the pipeline integral rigidity, durability is good.
The utility model is rational in infrastructure, has not only realized the fluid in the pipeline is filtered, but also has realized filter core is carried out backwash, operation, easy to maintenance.
Description of drawings
The utility model will be further described below in conjunction with accompanying drawing, and Fig. 1 is structural representation of the present utility model.
The specific embodiment
But a kind of back-flushing filtering device, as shown in Figure 1, side on trunk line 1 is installed with T type triple valve 2, on the trunk line 1 of opposite side the one 3 pass joint 3 is installed, trunk line 1 outlet that connects at the one 3 pass joint 3 is installed with first valve 4, its outlet of filter with barrel-shaped filter core 9 is connecting another interface of the one 3 pass joint 3 by branch pipe(tube), the import of filter is connecting the 23 pass joint 6 by branch pipe(tube), an interface of the 23 pass joint 6 is connecting another interface of T type triple valve 2 by branch pipe(tube), on the outlet stool road that another interface of the 23 pass joint 6 connects second valve 7 is installed.The structure of filter is on cylindrical shell 8 its closed end walls of an end sealing import to be set, the cylindric pressure cap 10 of outer end sealing is installed by screw thread on the inwall of cylindrical shell 8 open side, the openend of pressure cap 10 cylinders is connecting the barrel-shaped filter core 9 of outer end sealing, the arranged outside that has the cylindrical wall of screw thread at pressure cap 10 the undergauge outer circle wall, at the undergauge outer circle wall through hole is set, the outlet that arranges at cylindrical shell 8 walls communicates with the cavity that pressure cap 10 undergauge outer circle walls and cylindrical shell 8 inwalls constitute.Import trunk line 1 at T type triple valve 2 is installed with first Pressure gauge 5, and the trunk line 1 between the one 3 pass joint 3 and first valve 4 is installed with second Pressure gauge 11.
