Description

T-shaped filter

Technical Field

The utility model belongs to the technical field of the valve, especially, relate to a filter.

Background

The filter is a small device for removing a small amount of solid particles in liquid, can protect the normal operation of the device, is called as a T-shaped filter because the T-shaped filter is like a letter T in appearance, impurities are blocked when fluid enters a filter cylinder with a filter screen of a certain specification, clean filtrate is discharged from a filter outlet, and when the filter needs to be cleaned, the detachable filter cylinder is taken out and is installed again after treatment, so the use and maintenance are very convenient.

Traditional steel lining fluorine plastic filter, processing and inside lining are comparatively complicated, and the filter screen area receives body inner chamber size influence, and effective filter area is big enough, leads to often needing the filter screen in the scavenge pipe body. The filter can only be installed on a pipeline in the horizontal or vertical direction, the medium flow direction also needs to be in a single direction, backflow filtration cannot be achieved, and 90-degree-direction filtration of the pipeline cannot be achieved.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the main technical problem that will solve is how to realize increase area of filtration's filter.

The utility model discloses a realize through following technical scheme:

the utility model provides a T type filter, includes body, tube cap and filter screen, inlays in the body inner wall in the filter screen, and the body has three oral area, wherein has two oral areas to be import and export respectively, and another oral area is equipped with the tube cap, body import and export looks vertical setting, there is the clearance filter screen and body exit change baffling department of fluid flow direction. Import and export the baffling department that changes the flow direction with filter screen and body and set up the clearance between, the utility model discloses well this baffling department is for changing the position department of fluid flow direction, also is the juncture of T type filter vertical part and direct part exactly to for the oral area of vertical part, make the area of contact increase between fluid and the filter screen, almost the filter screen except that fixed position other parts are whole can both play the filter effect with the fluid contact, thereby improve the utilization ratio and the filtration efficiency of filter screen.

In order to facilitate cleaning of dirt remained after filtering in the pipe body, the pipe cover is provided with a drain outlet, the pipe cover and the surface of the filter screen are convenient to clean after the drain outlet is opened, and the pipe cover does not need to be disassembled.

After the liquid enters the filter screen through the pipe body, solid impurity particles are blocked in the filter screen or outside the filter screen, and clean fluid passes through the filter screen and is discharged from the filter outlet. Is used for eliminating impurities in the medium so as to protect the normal use of the valve and equipment. The utility model discloses body structure adopts T type structure, makes the filter can install in the position of pipeline redirecting, has broken away from traditional project organization, can only install on pipeline single direction, and the filter screen is because of inlaying in the body inner chamber, therefore makes its effective filtration area increase, can divide into the refluence flow, positive baffling according to the difference of medium flow direction to satisfy the operating mode requirement of various reexamings.

Fig. 1 is a sectional view of the present invention.

Detailed Description

The present invention will be further described with reference to the following examples.

Examples

A T-type filter as shown in fig. 1, which is a fluid pipeline filter, comprising a T-shaped pipe body 1, a pipe cover 2 connected to the pipe body 1 and a filter screen 3, wherein the filter screen 3 is embedded in the inner wall of the pipe body 1, the pipe body 1 has three opening parts, two of the opening parts are straight-through type, the other opening part is perpendicular to the straight-through part, two of the opening parts are respectively an inlet and an outlet, the opening part of one of the straight-through parts is an inlet or an outlet, the opening part of the other straight-through part is connected with the pipe cover 2, the opening part of the vertical part is an outlet or an inlet, the inlet and the outlet of the pipe body 1 are arranged perpendicularly, a gap exists between the filter screen 3 and a baffling part 4 of the pipe body 1, which changes the flow.

In order to further enlarge the area of the fluid passing through the filter screen 3, the filter screen 3 is designed into a structure with a large caliber at one end and a small caliber at the other end, the small caliber end of the filter screen 3 is connected with the pipe cover 2, and the large caliber end of the filter screen 3 is arranged in the inner cavity of the pipe body 1. The filter screen 3 is fixed by the pipe cover 2, the inner wall of which is provided with a positioning part 5 for inserting the small-caliber end of the filter screen 3. The positioning part 5 is designed as an inward concave groove. The small-bore end of the filter screen 3 is inserted into the groove of the pipe cover 2 to prevent the filter screen from moving. The cross section of the filter screen 3 is of a trapezoidal structure. The cross section of the filter screen 3 is designed into a right-angle trapezoidal structure as an optimization, and the right-angle side part is arranged close to the inner cavity of the pipe body 1.

In order to adapt to corrosive fluid media, the inner walls of the pipe body 1 and the pipe cover 2 are lined with an inner lining layer 6, and the inner lining layer 6 is made of fluoroplastic or fluorinated ethylene propylene copolymer. In order to make the filter screen 3 not easy to corrode, the filter screen 3 is made of polytetrafluoroethylene materials.
