Abstract

The utility model relates to a non-return type disconnector, which is connected with a pressure meter and is used for a direct water drinking preparing system. The non-return type disconnector for preparing direct drinking water has simple and reliable structure; liquid can be supplied in single direction, and the utility model has the advantages of accurate pressure measuring, no polluting and buffering functions, and low cost. The utility model can realize one-way switching of diaphragms by mainly using the non-return structure; the water on the system end can be only conducted with one-way supplying to a pressure measuring end, and counter-current flow can not be generated. Accordingly, non-return partition can be realized; the system end is connected with a cavity through small holes, and the non-return type disconnector for preparing direct drinking water can simultaneously have buffering functions.

Description

Direct drinking preparation inverse-stopping type cut off device

Technical field

The inverse-stopping type cut off device is used in a kind of direct drinking preparation that can compensate automatically, belongs to the direct drinking manufacturing equipment and uses the accessory field.

Prior art

As everyone knows, the direct drinking preparation system is always avoided any dead angle as possible, to prevent the bacteria breed polluted water, and the Pressure gauge that pressure measurement is used is because of its structure and use character, can cause the pollution of direct drinking easily, cut off device is exactly that a kind of Pressure gauge that prevents pollutes the meter connector of direct drinking, existing diaphragm type cut off device separates direct drinking preparation system and Pressure gauge fully, its shortcoming is when long-time the use, because pressure tapping place is inevitably leaked the liquid of Pressure gauge end is reduced gradually, and then make the pressure gauge reading distortion.

Goal of the invention of the present utility model is to provide a kind of novel direct drinking preparation inverse-stopping type cut off device design simple in structure.

Goal of the invention of the present utility model is achieved in that the diaphragm that adopts band inverse-stopping type structure replaces the common planar diaphragm and makes pressure transmission device, the check structure of diaphragm makes the water can only be from system end feed pressure table end, and can not adverse current, thereby can make the accurate measuring system pressure of Pressure gauge, contaminated system has not again realized the purpose of invention.

The specific embodiment

Below with reference to above accompanying drawing, the specific embodiment of the present utility model is done further detailed description.

This inverse-stopping type cut off device is separated into two chambeies by diaphragm (2), chamber A and chamber B, chamber A is connected with system end (9) by aperture (10), chamber B is connected with Pressure gauge end (7), hollow column cap (6) is the part of the diaphragm (2) of band check structure, hollow column cap (6) has column cap hole (5) connected chamber A and chamber B, resilient sleeve (4) is overlapped on the hollow column cap (6), hollow column cap (6) on the hollow column cap is sealed, during initialization, chamber A and chamber B are full of water simultaneously, guarantee that hollow column cap (6) can not contact on the B wall of chamber, at this moment two cavity pressure balances, column cap hole (5) is sealed by resilient sleeve (4), when the chamber B water yield reduced, the amount of movement of diaphragm (2) strengthened, and column cap hole (5) can contact on the B of chamber, chamber A pressure is greater than chamber B pressure, the sealing that chamber A water is washed resilient sleeve (4) open enters chamber B, and up to two cavity pressure balances, column cap hole (5) are sealed once more by resilient sleeve (4).Otherwise when chamber B pressure during more than or equal to chamber A pressure, under the elasticity of resilient sleeve (4) self and the hydraulic pressure effect of chamber B, column cap hole (5) by resilient sleeve (4) sealing, water can not enter chamber A, thereby has realized the purpose that check cuts off.Because system end links to each other by aperture (10) with chamber A, chamber A holds the water variation and slows down, and then is with diaphragm (2) movement velocity of check structure to slow down, and makes the preparation of this direct drinking have cushioning effect with the inverse-stopping type cut off device.

Claims

1. the inverse-stopping type cut off device is used in a direct drinking preparation, by lower house (1), and diaphragm (2), upper shell (3), resilient sleeve (4), column cap hole (5), hollow column cap (6), Pressure gauge end (7), connecting bolt (8), system end (9), aperture (10) is formed, it is characterized in that: be with hollow column cap (6) and resilient sleeve (4) on the diaphragm (2), column cap hole (5) is arranged on the hollow column cap (6).

2. the inverse-stopping type cut off device is used in 1 described direct drinking preparation according to claims, and it is characterized in that: chamber A is connected with system end (9) by aperture (10).
