Abstract

The utility model relates to a pipeline filter with an outside filtering pump head. A valve body is spherical; an inlet pipe port is arranged above the valve body; the outlet pipe port is arranged at the lateral face of the valve body; the inlet tube port is opposite to a blowdown pipe port on which a bottom blocker is arranged; the outlet pipe port is opposite to a blocking cover; the axial direction of a filtering cylinder is consistent with the direction of the outlet pipe port. The water flow direction of the filter is in a corner type; the pipe distribution of the system of the utility model has compact structure, saving one elbow joint; the utility model can block solid dirt out of the filtering cylinder; the solid dirt can be discharged from a blowdown port without the need of the dismounting of a press cover; the normal operation of pumps is not be affected; the globe body structure of the filter is favorable to blowdown and the uniform water distribution of water flow; the utility model has small water flow resistance; the hole opening rate of the filtering hole of the filtering cylinder reaches 100 percents.

Description

Outer filter pump head piping filter

The utility model relates to a kind of piping filter.

Existing piping filter comprises that one has the Y-valve body of water inlet pipe mouth, effluent pipe mouth, end-of-the-pipe and places garden cylindricality filter cylinder in the valve body, and fluid to entering valve body, comes out belong in filter type from the filter opening of filter cylinder barrel from cartridge axis.The most outstanding shortcoming of interior filter type is that the solid sundries that is filtered is deposited in the filter cylinder, and the deposition of solid sundries makes filter cylinder go out the water surface and reduces, and increases resistance to water-flow.Sometimes filter cylinder is inhaled badly and blocked pipeline, therefore, frequent termination of pumping cleaning, be badly in need of improving.

The purpose of this utility model provides a kind of outer filter pump head piping filter, makes it compact conformation, and solid dirt is trapped in outside the filter cylinder, need not dismantle gland, just can be got rid of by sewage draining exit, does not influence the normal operation of pump.

The technical solution of the utility model is:

Outer filter pump head piping filter, comprise that one has the valve body of water inlet pipe mouth, effluent pipe mouth, end-of-the-pipe and places the interior garden cylindricality filter cylinder of valve body, it is characterized in that: valve body is spherical in shape, water inlet pipe mouth up, effluent pipe mouth is in the side, and water inlet pipe mouth is relative with end-of-the-pipe, has the end stifled on the end-of-the-pipe, effluent pipe mouth is relative with blanking cover, and cartridge axis is to consistent with the effluent pipe mouth direction.

Blanking cover is linked to each other with valve body by bolt.

The flow direction that is somebody's turn to do outer filter pump head piping filter is to be entered in the globe valve body cavity by the water inlet pipe mouth that places the top, garden cylindricality filter cylinder stops runner, liquid can enter in the tube by filter opening, change 90 ° and flow to outlet conduit, solid sundries is then cut outside filter cylinder, is deposited on the sewage draining exit place, but the ends such as sewage draining exit mounting ball valve, gate valve, are stifled, open valve and get final product blowdown, needn't dismantle, needn't termination of pumping.

The utility model has the advantages that: this filter water (flow) direction is an angie type, the direction of promptly intaking and water outlet direction are angled, compact conformation on system's pipe arrangement, area does not take up room separately, can save 90 ° of elbows, both reduce installing space, saved pipe fitting again, reduced the pump house area occupied; Solid dirt is trapped in outside the filter cylinder, need not dismantles gland, just can get rid of, do not influence the normal operation of pump by sewage draining exit; This filter adopts sphere structure, helps blowdown, helps the current uniform water distribution, and resistance to water-flow is little, and the percent opening of filter cylinder filter opening reaches 100%, and filter type filter can only reach 70% in the Y shape; Sewage draining exit adopts the t-joint mode, i.e. blowdown double as pipe-supporting is again used; Filter cylinder is the circumference water inlet, and stressed even, pressure-bearing is big, can not inhaled bad by water pump.

Below in conjunction with drawings and Examples the utility model is described in detail:

Fig. 1 is a structural representation of the present utility model.

As shown in the figure, outer filter pump head piping filter, comprise that one has the valve body of water inlet pipe mouth, effluent pipe mouth, end-of-the-pipe and places the interior garden cylindricality filter cylinder of valve body, its valve body 1 is spherical in shape, water inlet pipe mouth 7 up, effluent pipe mouth 8 is in the side, water inlet pipe mouth 7 is relative with end-of-the-pipe 9, have the end stifled 4 on the end-of-the-pipe 9, effluent pipe mouth 8 is relative with blanking cover 3, filter cylinder 2 axial consistent with effluent pipe mouth 8 directions.Blanking cover 3 is linked to each other with valve body 1 by bolt 6, and 1 of blanking cover 3 and valve body have sealing gasket 5.

Claims

1, a kind of outer filter pump head piping filter, comprise that one has the valve body of water inlet pipe mouth, effluent pipe mouth, end-of-the-pipe and places the interior garden cylindricality filter cylinder of valve body, it is characterized in that: valve body is spherical in shape, water inlet pipe mouth up, effluent pipe mouth is in the side, and water inlet pipe mouth is relative with end-of-the-pipe, has the end stifled on the end-of-the-pipe, effluent pipe mouth is relative with blanking cover, and cartridge axis is to consistent with the effluent pipe mouth direction.

2, outer filter pump head piping filter according to claim 1, it is characterized in that: described blanking cover is linked to each other with valve body by bolt.
