Description
Technical field
This utility model farmland dual-purpose diaphragm valve, it relates to fluid level control valve field, and a kind of farmland pipeline pressure irrigates special valve, has double-purpose functional, i.e. can be with Artificial Control, the water level that can supporting with electromagnetic valve and ball-cock assembly automatically control in farmland again.
Background technology
Existing field pipeline irrigation water control valve, butterfly valve, ball valve is typically used to control the water level start and stop in farmland, owing to above two valve start and stop need to rotate, in use wear and tear relatively big, easily leak, waste water resource, due to switch resistance greatly, farmland controlling water level typically uses manual operation, as used automatically controlled power consumption relatively large for butterfly valve, ball valve simultaneously, it is therefore necessary to improved existing technology, to meet pipeline irrigation, valve control water is actually needed.
Summary of the invention
In order to solve the problems referred to above, this utility model purpose is to provide for a kind of Novel farmland dual-purpose diaphragm valve, easy for installation having, rational in infrastructure, and on the basis of there is double-purpose functional, be arranged to be moved pin (5) by valve seat (1), valve gap (2), diaphragm (3), return spring (4), anti-blocking, hand switch (6), dual-purpose interface (7), pilot hole (8), anti-blocking filter element (9), circular outlets (10), annular water inlet (11) form.
Of the present utility model it is technically characterized in that farmland dual-purpose diaphragm valve, annular water inlet (11), circular outlets (10) it is provided with in valve seat (1), diaphragm (3) is provided centrally with pilot hole (8), pilot hole (8) hypomere is provided with anti-blocking filter element (9), epimere is provided with return spring (4), anti-blocking moves pin (5), and the upper end of valve gap (2) is provided with hand switch (6), dual-purpose interface (7).
Described annular water inlet (11), circular outlets (10) are arranged to the positive reverse direction flow of the same mouth of pipe.
The anti-blocking that described pilot hole (8) is equipped with moves pin (5), return spring (4) is the most Wrapping formed elastic mechanism of a steel wire.
Described hand switch (6) is provided with dual-purpose interface (7).
This utility model compared with prior art provides the benefit that: owing to existing butterfly valve, ball valve are the switches using rotation to control water, thus easily cause sealing part abrasion and leak, affect the service life of valve, waste water resource, this utility model farmland dual-purpose diaphragm valve, water supply Guan Shuishi, diaphragm moves up and down without abrasion, hand switch is used to control diaphragm and the hydraulic pressure in valve gap, it is achieved the unlatching of valve is closed down, thus ensure that the life-span of diaphragm valve.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is sectional view of the present utility model.
Detailed description of the invention
nullIt is that this utility model agriculture is by dual-purpose diaphragm valve referring to the drawings，Valve seat (1) is provided with annular water inlet (11)、Circular outlets (10)，Valve gap (2) upper end is provided with hand switch (6)、Dual-purpose interface (7)，Diaphragm (3) is provided with pilot hole (8)、Return spring (4)、Anti-blocking moves pin (5)、Anti-blocking filter element (9)，During use，Annular water inlet (11) is connected with the water supply mouth of pipe，When manual operation is intake，When hand switch (6) is in out，The pressure of diaphragm (3) top is by dual-purpose interface (7) loan at call，Hydraulic pressure jack-up diaphragm (3) in annular water inlet (11) starts water inlet，Current flow into farmland by the circular outlets (10) of diaphragm (3) lower section，When manual operation hand switch (6) is in pass，Hydraulic pressure enters diaphragm (3) top inner chamber by the pilot hole (8) at diaphragm (3) center，Close down into water under pressure and return spring (4) dual function，When employing automatically controls，Hand switch (6) is open in usual，Dual-purpose interface (7) is docked with electromagnetic valve or ball-cock assembly by flexible pipe，As pilot valve，Automatically control the water level switch in farmland，Owing to pilot hole (8) lower section is provided with anti-blocking filter element (9)，It is provided above anti-blocking and moves pin (5)，So that pilot hole (8) keeps unimpeded，Switching function is stable.
Claims (4)
1. the dual-purpose diaphragm in farmland valve, by valve seat (1), valve gap (2), diaphragm (3), return spring (4), anti-blocking moves pin (5), hand switch (6), dual-purpose interface (7), pilot hole (8), anti-blocking filter element (9), circular outlets (10), annular water inlet (11) composition, it is characterized in that: farmland dual-purpose diaphragm valve, annular water inlet (11) it is provided with in valve seat (1), circular outlets (10), diaphragm (3) is provided centrally with pilot hole (8), pilot hole (8) hypomere is provided with anti-blocking filter element (9), epimere is provided with return spring (4), anti-blocking moves pin (5), the upper end of valve gap (2) is provided with hand switch (6), dual-purpose interface (7).
