Abstract

The utility model discloses a mesh-typed screen filter for plastic shed use consisting of a tubular hosing (1), an end cover (2), a tubular filtering net (3), a seal ring (4), a seal gasket (9) and a blanking cover (5). A water inlet pipe connector (6) and a water outlet pipe connector (7) are arranged on the end cover (2); the middle part of the interior end cover (2) is provided with a clapboard (8) which is circular; the lower port of the clapboard (8) is fastened together with the tubular filtering net (3); the lower port of the tubular hosing (1) is fastened with the blanking cover (5); the interior diameters of the water inlet pipe connector (6) and the water outlet pipe connector (7) are 1 1/2. The mesh-typed screen filter for plastic shed use can be easily installed and convenient for use, has a low setting, cost and using fee and can be widely applied to the field of irrigation association use for a plastic shed with 50-80 meters long.

Description

Plastic greenhouse screen mesh type filter

Technical field

The utility model relates to a kind of filter that is used for slight irrigation, drip irrigation project, and particularly a kind of plastic greenhouse screen mesh type filter is applicable to the plastic greenhouse micro drip-irrigation engineering that 50-80 rice is long.

Background technology

Granular membrane is the vitals that is used for hot house micro drip-irrigation engineering, and it is contained in the head end of water inlet manifold, supplies water by filter, and the silt in the water, contaminant filter is clean, is difficult for stopping up to guarantee mini sprinkler, water dropper, evenly supplies water.The present screen mesh type filter that uses, the interior diameter of its water-in and water-out pipe joint have at 1 o'clock, several specifications such as 2 o'clock, and 1 o'clock screen mesh type filter maximum stream flow is 6.3m ³/ hour, be applicable to length be 50 meters with interior hot house, be the hot house of 50-80 rice for length, to use water-in and water-out pipe joint interior diameter be 1 o'clock just too little, if with 21 o'clock, then the usage charges height, complexity is installed, if directly too big again with 2 o'clock wasted the water yield, and the cost height.

Summary of the invention

It is the hot house and the plastic greenhouse screen mesh type filter easy for installation, that usage charges are low, cost is low of 50-80 rice that the purpose of this utility model is to provide a kind of length that is applicable to.

For reaching above purpose, the technical scheme that the utility model adopted is: this plastic greenhouse screen mesh type filter, by tubular shell, end cap, the tubular screen pack, sealing ring, sealing gasket, blanking cover constitutes, on end cap, establish admitting pipe joint and titting water outlet, the bosom of end cap is provided with dividing plate, dividing plate is circular, the end opening of dividing plate and tubular screen pack are fixed, the water that water inlet pipe is input into successively passes through admitting pipe joint, in circular dividing plate middle part and the tubular screen pack, enter titting water outlet from the tubular screen pack outside again, thereby make water obtain filtering, the fixing blanking cover of going up of the end opening of tubular shell when the silt that filters out and impurity fall into the end opening of tubular shell, can be opened blanking cover and take out from end opening, when the interior diameter of its admitting pipe joint and titting water outlet is 1 , to adapt to the output of the long hot house of 50-80 rice.The utility model is also implemented by following measure: the suitable for reading and end cap end opening of described tubular shell is for being threaded, and sealing ring is established in the junction; The end opening of tubular shell and blanking cover are also for being threaded, and connector is established sealing gasket; In the upper and lower port of tubular screen pack, establish the stretching ring respectively, the lower end of tubular screen pack and upper end be set in the tubular shell end opening and the end opening of the dividing plate of end cap in, and be embedded with corresponding sealing ring, make its sealing.

Advantage of the present utility model is: irrigate supporting use with the hot house that 50-80 rice is long, easy to install, typing, cost is low, usage charges are low.
