Description
Technical field
The present invention relates in the modern agriculture drip irrigation technique circulating water filtration treatment field in water filtration and industrial production, and be particularly related to a kind of two-bit triplet backwash valve open in usual.
Background technique
Backwash valve applies in the modern agriculture drip irrigation technique circulating water filtration treatment in water filtration and industrial production in a large number.The hydraulic control valve door of full-automatic back washing filtration system special use, tube wire system pressure-driven can automatically be carried out two-bit triplet and be switched, and realizes the filter automatic backwash.Its reliability is high, can guarantee that vice versa in the situation that without safeguarding long-time steady operation, it can change the flow direction of water reposefully, closes water intake when the backwash mouth is opened, and avoids filter to overflow or clear water mixes mutually with waste water.
In prior art, backwash valve is applied to have at least the automatic back flush filtration system of two filter elements arranged side by side, that is: in backwash process, the clean water after a filter element filters is as the sparge water of another one filter element.After receiving the hydraulic signal that controller sends, change the flow direction of current in backwash valve: close water intake, open drain opening, the clean water after other filter element filters enters this element and rinses, and sparge water is discharged through floss hole.
Yet the backwash valve complex structure of prior art, manufacture cost is higher, introduces price by the import channel high, has increased the weight of domestic agricultural irrigation and industrial production user's economic burden, is unfavorable for that the water-saving technology in China's industrial and agricultural production is promoted.
Summary of the invention
The present invention proposes a kind of two-bit triplet backwash valve open in usual, and simple in structure, manufacture cost is lower, reduces modern agriculture and industrial investment and operation cost, further promotes the modern agriculture drip irrigation technique, improves industrial water circulation use rate.
In order to achieve the above object, the present invention proposes a kind of two-bit triplet backwash valve open in usual, comprise: valve body and the valve gap that is arranged on described valve body, be provided with water inlet on described valve body, drain opening and rinse mouth, be provided with the control valve port on described valve gap, be provided with barrier film between described valve body and valve gap, described barrier film is provided with pull bar, the other end of described pull bar is provided with piston plate, be provided with the dividing plate with opening in described valve body described valve body is separated into water-inlet cavity and drain chamber, described piston plate is controlled sealing by pull bar or is opened the opening of described dividing plate.
Further, be provided with conical coil spring below described piston plate, it is arranged in above described water inlet.
Further, the barrier film between described valve body and valve gap is isolated into control chamber with upper space, and described control chamber injects by described control valve port or discharge water.
Further, described valve inner is provided with pressing plate, and described pull bar is arranged in described pressing plate.
Further, be provided with support ring and seal ring between described pressing plate and piston plate.
Further, described pressing plate and support ring adopt engineering plastics to make.
Further, the material of described barrier film is rubber.
Further, the material of described valve body is cast carbon steel, and is coated with rust proof paint.
Further, the material of described pull bar is stainless steel.
The two-bit triplet backwash valve open in usual that the present invention proposes is realized the piston plate motion by the pressure reduction of piston plate both sides, can automatically carry out two-bit triplet and switch, and realizes the filter automatic backwash.The barrier film driving structure only needs very short stroke can change reposefully the flow direction of water, closes water intake when the backwash mouth is opened, and vice versa.Avoid filter to overflow or clear water mixes mutually with waste water.Simple in structure, reliability is high, can guarantee in the situation that without safeguarding long-time steady operation.Manufacture cost is lower, reduces modern agriculture and industrial investment and operation cost, further promotes the modern agriculture drip irrigation technique, improves industrial water circulation use rate.
Description of drawings
Figure 1 shows that the two-bit triplet backwash valve structural representation open in usual of preferred embodiment of the present invention.
Embodiment
Provide the specific embodiment of the present invention below in conjunction with accompanying drawing, but the invention is not restricted to following mode of execution.According to the following describes and claims, advantages and features of the invention will be clearer.It should be noted that, accompanying drawing all adopts very the form of simplifying and all uses non-ratio accurately, only is used for convenient, the purpose of the aid illustration embodiment of the present invention lucidly.
Please refer to Fig. 1, Figure 1 shows that the two-bit triplet backwash valve structural representation open in usual of preferred embodiment of the present invention.the present invention proposes a kind of two-bit triplet backwash valve open in usual, comprise: valve body 9 and the valve gap 1 that is arranged on described valve body 9, be provided with water inlet A on described valve body 9, drain opening B and rinse mouth C, be provided with on described valve gap 1 and control valve port D, be provided with barrier film 2 between described valve body 9 and valve gap 1, described barrier film 2 is provided with pull bar 3, the other end of described pull bar 3 is provided with piston plate 8, be provided with the dividing plate 7 with opening in described valve body 9 described valve body 9 is separated into water-inlet cavity 100 and drain chamber 200, described piston plate 8 is controlled sealing by pull bar 3 or is opened the opening of described dividing plate 7.
The preferred embodiment according to the present invention, described piston plate 8 belows are provided with conical coil spring 10, and it is arranged in described water inlet A top.Barrier film 2 between described valve body 9 and valve gap 1 is isolated into control chamber 300 with upper space, and described control chamber 300 injects by described control valve port D or discharge water.Described valve body 9 inside are provided with pressing plate 4, and described pull bar 3 is arranged in described pressing plate 4, and the epicoele of described barrier film 2 is control chamber 300, and the cavity of resorption of barrier film 2 should be considered as communicating with drain chamber 200, and it communicates with drain chamber 200 by the hole of pull bar 3 at pressing plate 4 places.Further, be provided with support ring 5 and seal ring 6 between described pressing plate 4 and piston plate 8, described pressing plate 4 and support ring 5 adopt engineering plastics to make, the material of described barrier film 2 is rubber, the material of described valve body 9 is cast carbon steel, and is coated with rust proof paint, and the material of described pull bar 3 is stainless steel.
