Abstract

The utility model relates to a no resistance water outlet valve, comprising a water outlet pipe, a water pressing cover with a hat brim, a screw rod and a beam, wherein, the inner wall of the water outlet pipe is provided with screw thread, and the relative two sides of the outer wall is provided with a star-shaped arm which is fixed with the relative two sides of the outer wall; the middle part of the beam is provided with a screw hole, and the two sides are respectively fixed with the end part of the star-shaped arm; the screw rod penetrates through the screw hole of the middle part of the beam and is mutually matched with the screw hole. Therefore, the valve of the utility model has the advantages of large water outlet amount, convenient use, good sealing performance, easy disassembling and maintenance, energy saving, no resistance, large compression resistance, small abrasion, etc., and the utility model is an ideal substitute product of the existing low-pressure pipeline irrigation of the farmland.

Description

No resistance water outlet valve

The utility model belongs to the valve that low pressure irrigation is used, and is specifically related to the non-resistance outlet valve.

The valve shape that existing low pressure irrigation is used mostly is Fig. 1, Fig. 2 shape, and its screw mandrel 1 fixes with the setting-out lid 2 of vizored, and the nut of band muscle is arranged in the outlet pipe 3, and outlet pipe inwall bottom also has screw thread.Therefore, by on the water outlet standpipe that is threaded in low pressure irrigation the time, the setting-out lid that rotary screw rod, screw mandrel have shade rotates thereupon with the outlet pipe bottom of this valve, opens or the effect of throttle down thereby reach.This valve is because its setting-out cover tape has shade, so can prevent current ejection erosion control pond, in addition, its structure is also simple.But because its screw mandrel and setting-out lid fixes, it is absolute vertical that gland and screw mandrel must guarantee, so its difficult sealing.Because the nut of band muscle is arranged in the outlet pipe of this valve, the resistance when making its water outlet is big, water-outlet quantity is little, waste energy.

That the purpose of this utility model provides is easy to use, water-outlet quantity big, good airproof performance, dress easy to break maintenance, energy-conservation without hindrance and outlet valve.

For achieving the above object, non-resistance outlet valve of the present utility model has the threaded outlet pipe of inner wall belt, the setting-out lid of screw mandrel and vizored.There are fixing with it ┐ shape arm, the end of two ┐ shape arms and the two ends of the crossbeam that there is tapped hole at the middle part to be fixedly linked on relative two outer side walls of the threaded outlet pipe of inner wall belt respectively.Screw mandrel and crossbeam are with threaded hole with screw-thread fit and pass this hole, and its other end and vizored setting-out lid flexibly connect fixing.

Because non-resistance outlet valve of the present utility model adopts screw mandrel and vizored setting-out lid movable connection method to replace the screw mandrel of existing flowing water Valve and the vertical fixing Placement of vizored setting-out lid can reach the mouth of pipe that makes setting-out lid sealing outlet pipe by free gap certain between screw mandrel and the vizored setting-out lid like this, and needn't require the setting-out lid definitely vertical with screw mandrel, so non-resistance flowing water Valve of the present utility model has good airproof performance, processes simple advantage.Because non-resistance outlet valve of the present utility model adopts crossbeam and ┐ shape arm to replace the nut of the inner band of the outlet conduit muscle of existing outlet valve.Thereby reduce current resistance, increase water flow, reach purpose of energy saving, in addition, it is big that non-resistance outlet valve of the present utility model also has a resistance to compression, advantages such as dress maintenance easy to break.

The structural representation of Fig. 1, existing outlet valve.

The structural representation of tep reel nut in Fig. 2, the existing outlet valve outlet pipe.

Fig. 3, the utility model non-resistance outlet valve structural representation.

Fig. 4, the utility model non-resistance outlet valve band ┐ shape arm outlet pipe and plan view.

Fig. 3, Fig. 4 have described an embodiment of the present utility model, it has setting-out lid 12, the screw mandrel 13 of outlet pipe 11, vizored, fixing with it shape arm 14 is arranged respectively on the outlet pipe two opposite outer wall, the crossbeam two ends are screwed with ┐ shape arm respectively, there is trapezoid block 15 with threaded hole at the crossbeam middle part, the screw mandrel upper end is porose, and there is notch 16 lower end.It is fluted 17 that the setting-out of vizored covers portion of portion, and the roundel 18 that is fixedly linked with the setting-out lid is arranged at the bottom, and roundel is with rubber seal 19, and rubber seal is covered lower surface with setting-out and is close together.Screw mandrel passes the screw at crossbeam middle part and with threads engaged, the screw mandrel lower end is connected by axle with vizored setting-out upper part of the cover groove.

Claims (3)

1, non-resistance outlet valve has setting-out lid, the screw mandrel of outlet pipe, vizored, it is characterized in that:

(1), it also has a middle part to be threaded the crossbeam in hole;

(2), be threaded on the outlet pipe inwall, have on the relative both sides of outer wall fixing with it

The shape arm;

(3), screw mandrel passes middle part crossbeam with threaded hole, the setting-out lid flexible connection of lower end and vizored, the two ends of crossbeam respectively with

Shape arm end is connected and fixed.

2, non-resistance outlet valve according to claim 1 is characterized in that: the setting-out of described vizored covers that its top is fluted, be connected by axle between screw mandrel and the setting-out lid groove.

3, non-resistance outlet valve according to claim 1 and 2 is characterized in that: the fixing disk in surface is with it arranged at described vizored setting-out lid bottom, is with seal ring on the disk, and seal ring is close to setting-out lid lower surface.
