Detailed Description

In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings.

As shown in fig. 1; kitchen sewer water pressure mediation piston includes:

the piston body 1 is a cylinder with a through hole in the middle. The outer side surface of the groove is provided with a first sealing groove and a second sealing groove which are juxtaposed up and down, and the groove depth and the groove width of the two sealing grooves are different. The inner side surface of the piston body 1 is provided with threads for connecting the joint 3 in a thread fixing mode;

the O-shaped ring provides a sealing surface which can be in sealing contact with a sewer, the piston is at least provided with two O-shaped rings, and each O-shaped ring can be respectively in sealing sleeve connection with the first sealing groove and the second sealing groove.

The hollow joint 3, preferably a pure copper pair wire joint, is arranged in the piston body 1. The diameters of the upper part and the lower part of the connector are small, the middle part is a convex annular shoulder 31 which is common in the field of connectors, and the diameter of the convex annular shoulder is larger than that of the upper part and the lower part of the connector 3; shoulder 31 may also preferably be a hexagonal body to facilitate wrench movement. The shoulder 31 facilitates axial positioning of the nipple 3 relative to the piston body 1. The lower part of the joint 3 is provided with an external thread which is matched with the piston body 1. The upper part of the joint 3 is also provided with external threads, so that the joint is convenient for connecting a water pipe in a threaded connection mode, and the water pipe is communicated with a water source. In addition, it should be understood by those skilled in the art that the higher the water pressure provided by the water pipe, the higher the water pressure entering the piston body 1, and the better the dredging effect. The piston body 1 is preferably made of pure copper.

O type circle that adopts the material to be rubber is through cup jointing in the sealed slot outside of piston body 1, and when O type circle damaged, the timely change O type circle of being convenient for.

As shown in fig. 1, both O-rings are elastic O-rings having a circular cross section, but have different wire diameters. The outer side surface of the O-shaped ring is in contact with the pipe wall of the sewer and is packaged in the sealing groove, and the sealing effect of isolating the sewer from the piston body is achieved after the O-shaped ring is extruded and deformed; o type circle joint is between the medial surface of piston body lateral surface and sewer. Namely, the dredging piston is arranged in the sewer. The structure and installation of the O-shaped ring are common technical means in the field of hydraulic sealing, and are not described herein. According to the national standard, the kitchen sewer external diameter is 50 mm, also called 50 downcomer in the industry, on this basis the actual internal diameter of the downcomer that each downcomer producer produced has slightly difference, though can utilize the elastic deformation of O type circle, compensate the internal diameter difference, but can not accurate, the wider application size has the sewer that deviates. Therefore, a first sealing groove and a second sealing groove which have different diameters, namely different groove depths, and two O-rings which have different sections, namely different wire diameters are designed, and the design method comprises the following steps: the wire diameter of one O-shaped ring is phi 3.5mm, and the wire diameter of the other O-shaped ring is phi 4 mm; the inner diameter of the first sealing groove is large, and the deformation space of the O-shaped ring provided by the sealing groove is small; the inner diameter of the second sealing groove is small, the groove depth is deeper, and the deformation space of the O-shaped ring provided by the sealing groove is large; one of the two O-shaped rings is selected for sealing, one of the two sealing groove clocks is selected for sleeving with the O-shaped ring, and four different sealing effects can be provided by combining the two sealing groove clocks in pairs to correspond to the sizes of sewers in four ranges. It will be appreciated by those skilled in the art that varying the channel width will also allow for varying the deformation space provided by the sealing channel and the inside of the drain to the O-ring.

As shown in fig. 2, the pull through piston further comprises a raw material belt layer, the raw material belt layer is wound on the side face of the piston body, and the first O-ring or the second O-ring is packaged in the corresponding first sealing groove or the second sealing groove. This facilitates the use of a layer of raw material strip to further increase the sealing properties of the sewer opening and the piston even if neither the sealing ring nor the sealing groove is able to seal the sewer. After the piston body is sleeved with the O-shaped ring, when the outer diameter of the O-shaped ring still cannot meet the sealing requirement of a sealed sewer, the O-shaped ring is wound with the thread seal tape, and the diameter is increased. The sewer pipe is sealed by the elasticity of the O-shaped ring and the raw material belt. The sealing performance is not enough, and the winding is continued, so that the thickness of the winding raw material belt layer is reduced. Ensuring that the product can be widely used.

The piston can also be used for dredging in other pipeline fields as will be appreciated by those skilled in the art. And the number of the sealing grooves is not limited to two but may be plural.

While certain exemplary embodiments of the present invention have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that the described embodiments may be modified in various different ways without departing from the spirit and scope of the present invention. Accordingly, the drawings and description are illustrative in nature and should not be construed as limiting the scope of the invention.
