Abstract
The utility model relates to a control valve in low-pressure water supply and sewerage conduits, in particular to a pneumatic valve. Compressed air is controlled to enter a seal cavity (11) through an inflation discharge pipe (3) or to discharge from the seal cavity (11), which enables a corrugated gas bag (2) on the lateral to upward bulge or downward shrink along a valve body (1) under the effect of the compressed air, and enables a valve core (12) and a valve port (5) to be opened or closed. The pneumatic valve has excellent corrosion resistant performance, high reliability and low manufacture cost, and is suitable to be used in ultra-low pressure agriculture water supply and sewerage systems needing automatic control in aquiculture and the like. Complicated mechanical devices such as a motor, a speed reducer, a cylinder piston and the like which are used in an existing control valve structure are avoided, thereby reducing the cost, and increasing the reliability.
Description
Technical field
The utility model relates to the control valve in the low pressure pipeline, specifically a kind ofly is applicable to aquaculture, and field irrigation utilizes air bag to realize the valve of switch.
Background technique
Water is the lifeblood of agricultural, can't realize just can't realizing the modernization of agricultural to the automatic control of plumbing, because electric valve generally adopts motor, speed reducer or electromagnetic structure in known water control valve door, pneumatic valve mostly adopts steam-cylinder piston, and above-mentioned valve relies on the complicated mechanical device drives to come the opening and closing valve, to realize the adjusting of fluid flow or pressure, the complex structure of valve, the operation part is many, the cost height, the rate of fault height, the operating cost height.Can't in development modernization agricultural, culture fishery, large size promote the use of.Restricting the development of modernization agricultural, culture fishery, this bottleneck effect also affects the promotion and application of other science and technology in modernization agricultural, culture fishery.
Summary of the invention
In order to overcome the complex structure of existing valve, the operation part is many, cost height, rate of fault height, the deficiency that operating cost is high.The present invention provides a kind of low pressure plumbing pneumatic valve simple in structure, it comprises valve body, (air bag is the cylinder type at the no end to air bag in the valve body, the side is a corrugated), charge and exhaust pipe is located on the blind plate of valve body bottom, blind plate clamps air bag bottom and the integrated rubber ring of air bag by screw and flange, both fixed air bag, valve body and air bag have also been sealed, make blind plate and air bag form Seal cage, pressurized air enters Seal cage by charge and exhaust pipe, air bag upwards expands at compressed-air actuated effect lower edge valve body and promotes spool and separate with valve port, valve port is opened, and liquid is just negotiable.Pressurized air in charge and exhaust pipe discharging Seal cage, air bag shrinks, and valve port is closed by spool, and liquid is blocked.
Description of drawings:
Figure is the structural representation of the utility model Pneumatic valve.
Among the figure: 1, valve body, 2, air bag, 3, charge and exhaust pipe, 4, seal ring, 5, valve port, 6, liquid entering hole, 7, liquid outlet, 8, flange, 9, blind plate, 10, screw, 11, Seal cage, 12, spool.
Embodiment
It comprises valve body (1), air bag (2), liquid entering hole (6), liquid outlet (7), valve port (5), spool (12), charge and exhaust pipe (3) and seal ring (4), this charge and exhaust pipe is located on valve body (1) the bottom blind plate (9), blind plate (9) clamps air bag (2) bottom and the integrated seal ring of air bag (2) (4) by screw (10) and flange (8), both fixed air bag (2) and also sealed valve body (1) and air bag (2), blind plate (9) has formed Seal cage (11) with air bag (2).When making pressurized air pass through charge and exhaust pipe (3), automatic control system enters Seal cage (11), to be undulatory cylinder type air bag (2) at compressed-air actuated effect lower edge valve body (1) upwards expand in the side promotes top spool (12) and upwards separates with valve port (5), valve port (5) is opened, and liquid flows into valve body (1) from liquid entering hole (6) and flows out from liquid outlet (7).Pressurized air in automatic control system makes charge and exhaust pipe (3) discharging Seal cage (11), air bag (2) shrinks, and spool (12) and valve port (5) closure stop flow of fluid, realize the unlatching of valve or close that the exhaust of filling of charge and exhaust pipe (3) is finished by automatic control system.Said structure mainly solves to be avoided having reduced cost as a large amount of complicated mechanical equipment such as motor, speed reducer, steam-cylinder piston that adopt in the existing control valve structure, has increased reliability.This pneumatic valve except that the material of air bag (2) be make by expandable rubber of inflation or plastic cement, other devices of valve are made by plastics.At acid, alkali, salt, working environment in good corrosion resistance, the reliability height, low cost of manufacture is applicable to aspects such as aquaculture, needs to use in the super-low voltage supply and drain water system of control automatically.
Claims (4)
1, a kind of pneumatic valve, it comprises valve body (1), air bag (2), liquid entering hole (6), liquid outlet (7), charge and exhaust pipe (3) and seal ring (4), it is characterized in that: charge and exhaust pipe (3) is located on valve body (1) the bottom blind plate (9), blind plate (9) clamps air bag (2) bottom and the integrated seal ring of air bag (2) (4) by screw (10) and flange (8), and spool (12) is on the top of valve port (5).
2, according to the said pneumatic valve of claim 1, it is characterized in that: air bag (2) is the cylinder type at the no end, and the side is a corrugated.
3, according to the said pneumatic valve of claim 1, it is characterized in that: the material of air bag (2) is to be made by pneumatic expandable rubber or plastic cement.
