Abstract
The utility model discloses a vacuum reservoir exhaust valve for a feeding pump, which consists of a valve body (1), an upper cover (2) and a handle (3). The middle part inside a cavity of the valve body (1) is provided with a boss (5). The boss (5) divides the inner cavity of the valve body (1) into an upper air cavity (9) and a lower air cavity (7). A screw (4) on the bottom of the upper cover (2) is in threaded connection with a center hole of the boss (5). The lower air cavity (7) is communicated with a connection hole (6). The boss (5) is provided with a through hole (8). Both upper and lower ends of the through hole (8) are respectively communicated with the upper air cavity (9) and the lower air cavity (7). A sealing gasket (10) is arranged between the upper mouth edges of the upper cover (2) and the valve body (1). The vacuum reservoir exhaust valve for the feeding pump has the advantages of simple structure, convenient use, easy operation, capability of only replacing the sealing gasket if the sealing gasket is aged, convenient maintenance, long service life, reduction of maintenance cost and reduction of production cost.
Description
Technical field
The utility model relates to a kind of improvement of valve, a kind of specifically feed pump vacuum tank outlet valve.
Background technique
In Citric Acid Production, need with feed pump liquid material be extracted into from agitating vessel in another container according to technological requirement and process, in agitating vessel, throw in raw material for the ease of the worker, generally agitating vessel is arranged on below ground, suitable for reading and the ground of agitating vessel is equal, the feed pump of agitating vessel conveniently then is put on the ground in order to overhaul, the feeding pump intake is higher than agitating vessel like this, for liquid is sucked in the feed pump in agitating vessel, connecting vacuum tank on the suction pipe of feed pump, the top of vacuum tank is provided with inlet valve and outlet valve, during work, open outlet valve and in vacuum tank, add water, air in the vacuum tank is discharged, treats that water level is higher than the pump housing in the vacuum tank, reach certain liquid level after, close inlet valve and outlet valve, start the feed pump operation and get final product.Used outlet valve is stop valve or ball valve at present, its deficiency is: in use, increase along with the switch number of times, the sealing of its sealing surface worse and worse, in the running of feed pump, usually because valve gas leakage can't feeding and influence production, and outlet valve can't be repaired after damaging, can only change, cause waste.
Summary of the invention
The purpose of this utility model is to provide a kind of operation simple in structure, easy to use, easy, is convenient to maintenance, the feed pump of long service life vacuum tank outlet valve.
In order to reach above purpose, the technological scheme that the utility model adopted is: this feed pump vacuum tank outlet valve, by valve body, loam cake and handle constitute, bottom at valve body is provided with attachment hole, the inwall of attachment hole is provided with screw thread, roof anchorage at loam cake is provided with handle, it is characterized in that: the middle part is provided with boss in the chamber of described valve body, boss is divided into upper gas chamber and lower air chamber with the inner chamber of valve body, the inwall of the center hole of boss is provided with screw thread, bottom at loam cake is fixed with screw rod, the lower end of screw rod is threaded with the center hole of boss, and lower air chamber is connected with attachment hole, is provided with through hole on boss, on the through hole, following two ends are connected with upper gas chamber and lower air chamber respectively, are provided with sealing gasket between the upper edge of loam cake and valve body.
The utility model is also implemented by following measure: described through hole is provided with 4-6, is symmetrical arranged along the periphery of boss.
The beneficial effects of the utility model are: operation simple in structure, easy to use, easy, if sealing gasket is aging, only needs to change sealing gasket and get final product, and be convenient to maintenance, long service life has reduced maintenance expenses, has saved cost of production.
Description of drawings
Fig. 1 is a structure cross-sectional schematic of the present utility model.
Embodiment
Make the utility model with reference to accompanying drawing 1.This feed pump vacuum tank outlet valve, by valve body 1, loam cake 2 and handle 3 constitute, be provided with attachment hole 6 in the bottom of valve body 1, the inwall of attachment hole 6 is provided with screw thread, so that on the short tube that is threaded in vacuum tank, roof anchorage at loam cake 2 is provided with handle 3, so that by handle with sleeve 3, can rotate loam cake 2, it is characterized in that: the middle part is provided with boss 5 in the chamber of described valve body 1, and the inwall of the center hole of boss 5 is provided with screw thread, be fixed with screw rod 4 in the bottom of loam cake 2, the lower end of screw rod 4 is threaded with the center hole of boss 5, and boss 5 tops are upper gas chamber 9, and the bottom is a lower air chamber 7, lower air chamber 7 is connected with attachment hole 6, on boss 5, be provided with through hole 8, on the through hole 8, following two ends are connected with upper gas chamber 9 and lower air chamber 7 respectively, are provided with sealing gasket 10 between the upper edge of loam cake 2 and valve body 1.
Described through hole 8 is provided with 4-6, is symmetrical arranged along the periphery of boss 5.
When using the utility model, be fixed on by attachment hole 6 on the short tube of vacuum tank, when needs add the water exhaust, handle with sleeve 3, upwards mention loam cake 2, open upper gas chamber 9, the air in the vacuum tank is discharged through short tube, attachment hole 6, lower air chamber 7, through hole 8 and upper gas chamber 9, when not needing exhaust, handle with sleeve 3, loam cake 2 moves down, and by sealing gasket 10, upper gas chamber 9 sealings is got final product.
Claims (2)
1. feed pump vacuum tank outlet valve, by valve body (1), loam cake (2) and handle (3) constitute, be provided with attachment hole (6) in the bottom of valve body (1), the inwall of attachment hole (6) is provided with screw thread, roof anchorage at loam cake (2) is provided with handle (3), it is characterized in that: the middle part is provided with boss (5) in the chamber of described valve body (1), boss (5) is divided into upper gas chamber (9) and lower air chamber (7) with the inner chamber of valve body (1), the inwall of the center hole of boss (5) is provided with screw thread, be fixed with screw rod (4) in the bottom of loam cake (2), the lower end of screw rod (4) is threaded with the center hole of boss (5), lower air chamber (7) is connected with attachment hole (6), on boss (5), be provided with through hole (8), on the through hole (8), following two ends are connected with upper gas chamber (9) and lower air chamber (7) respectively, are provided with sealing gasket (10) between the upper edge of loam cake (2) and valve body (1).
