Abstract

The utility model discloses a sewage isolator for a piston cylinder. An upper semi-ball casing (1) is provided with an upper through hole (2), a lower semi-ball casing (5) is provided with a lower through hole (6), and the upper semi-ball casing (1) and the lower semi-ball casing (5) are oppositely buckled to form a container. A capsule (4) is arranged in the oppositely buckled position, the capsule (4) corresponds to the shape of the inner part of the upper semi-ball casing (1) and the shape of the inner part of the lower semi-ball casing (5), and the container is divided into two mutually independent hollow cavities by the capsule (4). The utility model is the sewage isolator for a piston cylinder, which can completely prevent sewage media from entering a piston cylinder, and the sewage isolator for a piston cylinder can transmit the pressure of the sewage media to drive media which are beforehand positioned in the piston cylinder, and the sewage isolator for a piston cylinder can drive a piston to move, and the sewage isolator for a piston cylinder has the advantages of simple structure, reliable performance, convenient production and convenient maintenance.

Description

Piston cylinder sewage isolation mounting

Technical field

The utility model relates to a kind of sewage isolation mounting, particularly relates to a kind of sewage isolation mounting that is used for isolating on the piston cylinder clear water and sewage and transmission pressure.

Background technique

In autocontrol valve, be extensive use of piston driver, it is ducted fed sheet of a media that its working medium is generally the valve of flowing through.In order to guarantee piston energy flexible motion in piston cylinder, requiring driven medium is the less single fluid of ratio of viscosities, does not contain solid particle, as treated tap water, purified water etc.; But a large amount of fed sheet of a media such as rainwater, city domestic sewage, industrial sewage etc. are still arranged, its composition more complicated in the practical application; Prior art is to import and export the pipe laying filter at piston cylinder, prevents that the suspended matter of greater particle size from entering piston cylinder; But some particle diameters still can enter piston cylinder less than the small suspended matter in strainer screen aperture, because its flow velocity significantly reduces or be static for a long time, these small suspended matters just can precipitate or fouling, and then influence the normal operation of piston, even cause serious accident.Therefore, the user have to take the method for frequent clean piston cylinder, guarantees that piston normally moves.

The model utility content

Technical problem to be solved in the utility model provides a kind of piston cylinder sewage isolation mounting, and this device stops the sewage medium to enter piston cylinder fully, only the propagation of pressure of sewage medium is given the driven medium of the piston cylinder the inside of packing in advance, promotes piston motion.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of piston cylinder sewage isolation mounting, upper hemispherical shell is provided with through hole, lower hemisphere shell is provided with lower through-hole, described upper hemispherical shell and described lower hemisphere shell make-up are formed a container, be provided with capsule at the make-up junction point, the interior shape of described capsule and described upper hemispherical shell and described lower hemisphere shell adapts and described container is separated into two separate cavitys.

Described upper hemispherical shell is connected by bolt with lower hemisphere shell.

Described upward through hole and lower through-hole are located at the ball top of described upper hemispherical shell and described lower hemisphere shell respectively.

Adopt the piston cylinder sewage isolation mounting of technique scheme, capsule is made by rubber and is adapted with the interior shape of described upper hemispherical shell and described lower hemisphere shell, but undersized, following spherical shell and last spherical shell connect into an olivary integral body by bolt, and inside has just formed two cavitys of being isolated by capsule; Upper hemispherical shell is provided with through hole, lower hemisphere shell is provided with lower through-hole, can link to each other with pipeline with piston cylinder respectively.Capsule stops sewage medium (suspended matter that comprises nominal particle size) to enter piston cylinder fully, only the propagation of pressure of sewage medium is given the driven medium (clean water, hydraulic oil, emulsified liquid etc.) of the piston cylinder the inside of packing in advance, promotes piston motion.

In sum, the utility model is that a kind of complete sewage medium that can stop enters piston cylinder, only the propagation of pressure of sewage medium is given the driven medium of the piston cylinder the inside of packing in advance, promote piston motion and simple in structure, reliable performance, piston cylinder easily manufactured, easy to maintenance sewage isolation mounting.

Embodiment

Referring to Fig. 1, upper hemispherical shell 1 ball top is provided with through hole 2, lower hemisphere shell 5 balls top is provided with lower through-hole 6, upper hemispherical shell 1 is connected make-up with lower hemisphere shell 5 by bolt 3 and forms a container, be provided with capsule 4 at the make-up junction point, the interior shape of capsule 4 and upper hemispherical shell 1 and lower hemisphere shell 5 adapts and container is separated into two separate cavitys.

Its working principle is referring to Fig. 2 and Fig. 3, and the import and export of piston cylinder 7 are connected to the first sewage isolation mounting and the second sewage isolation mounting respectively:

Referring to Fig. 2, as sewage pressure P1 during greater than P2, sewage enters first lower hemisphere shell 51 of the first sewage isolation mounting, promote the inside first capsule, 41 upwards amoeboid movements, the clean driven medium (as clear water) that is placed in one is in advance clamp-oned the A chamber of piston cylinder 7, promoting piston 8 is moved to B by A, and the clean driven medium (as clear water) in the B chamber of piston cylinder 7 clamp-oned in second upper hemispherical shell 12 of the second sewage isolation mounting, promote second capsule, the 42 downward amoeboid movements of the inside, sewage is discharged second lower hemisphere shell 52 of the second sewage isolation mounting;

Referring to Fig. 3, as sewage pressure P2 during greater than P1, sewage enters second lower hemisphere shell 52 of the second sewage isolation mounting, promote the inside second capsule, 42 upwards amoeboid movements, the clean driven medium (as clear water) that is placed in one is in advance clamp-oned the B chamber of piston cylinder 7, promoting piston 8 is moved to A by B, and the clean driven medium (as clear water) in the A chamber of piston cylinder 7 clamp-oned in first upper hemispherical shell 11 of the first sewage isolation mounting, promote first capsule, the 41 downward amoeboid movements of the inside, sewage is discharged first lower hemisphere shell 51 of the first sewage isolation mounting;

The utility model is compared with filter, has following technical characterstic:

1, spacer medium spacer assembly epicoele, cavity of resorption are isolated by capsule, mutually not Communicate, the two ends medium is isolated fully, prevents that sewage from entering piston cylinder, thoroughly solves Piston cylinder affect its normal operation owing to precipitation of solid material in the sewage or fouling A difficult problem;

2, automatically cleaning the spacer assembly cavity of resorption is hemispherical dome structure, is difficult for deposition Foreign material, the every work of spacer assembly once, capsule just can push away sediment in the chamber downwards Squeeze, clean, discharge once, clean in the holding chamber.
