Abstract
The utility model discloses an intraductal rubber check valve, including valve cartridge and case, valve cartridge be the cavity rubber tube, and the case be oblique cylinder rubber bag, partly and the cavity rubber tube desmoplasia adhesion section of cylinder rubber bag sack to one side, and another part of cylinder rubber bag forms the laminating section with the laminating of cavity rubber tube to one side, and the girth of laminating section is greater than the girth of adhesion section, the both ends inner wall of cavity rubber tube is equipped with interior inflation clamp installation department. The utility model discloses intraductal rubber check valve adopts oblique cylinder rubber bag to be the case, possess extremely low head loss, allows 100% aperture nearly, and the valve is closely closed and to be avoided the refluence problem completely simultaneously, the simple installation, in only needing to insert the pipeline of corresponding bore with the valve, the front end of valve or rear end with the inflation clamp or the flange is fixed can, long service life adopts rubber to make, is difficult for rustting, and common greasy dirt in the resistant sewage, the practicality is strong, and the range of application is wide.
Description
Technical field
The utility model relates to a kind of one way stop peturn valve, specifically for stop waste water, waste gas to flow backwards pipe in a rubber check valve, be applicable to sewage outlet, exhaust vent, urban drainage pipe network, gargoyle of pumping station, dam overflow in the pipelines such as the mouth of a river.
Background technique
, there is following shortcoming in existing safety check:
1, all installations are all the outer installations of pipe or install in the joint of two pipelines, except must having certain installing space, also add the difficulty of installation, too increase cost simultaneously;
2, claimant in the number of patent application that on May 19th, 2009 applied for be in the patent application of ZL200910027738.6, adopt taper sheath as spool, realize draining and exhaust and one-way non-return, find through claimant's years of researches, taper sheath is only suitable for small-sized pipeline, because current technology cannot make large-scale taper sheath;
3, taper sheath is due to uniform force, and the draining of the first transaction of a day's business formula, hydraulic loss is relatively large.
Model utility content
The purpose of this utility model overcomes above-mentioned the deficiencies in the prior art, solves the technological deficiency existed at present, the utility model discloses rubber check valve in a kind of pipe.
The technological scheme that the utility model adopts is:
Rubber check valve in pipe, comprise valve cylinder and spool, described valve cylinder is hollow rubber pipe, described spool is oblique circular cylinder rubber bag, a part for described oblique circular cylinder rubber bag sack and described hollow rubber pipe Adhesion formation adhesion section, another part of described oblique circular cylinder rubber bag and hollow rubber pipe are fitted and are formed section of fitting, and the girth of described laminating section is greater than the girth of described adhesion section, and the two ends inwall of described hollow rubber pipe is provided with interior expansion clip assembly department.
Further, the angle angle of the scarf of described oblique circular cylinder rubber bag and the center line of hollow rubber pipe is 25 °-45 °.
Further, described oblique circular cylinder rubber bag sack has sent out seam one, and described seam one is one-body molded with oblique circular cylinder rubber bag sack, and described seam one matches with the seam two of hollow rubber inner tube wall.
The sack of oblique circular cylinder rubber bag has sub-fraction and hollow rubber inner tube wall to be sticked together, the major part of sack not with the adhesion of hollow rubber pipe.But normality and closed time, fit together.The two ends of hollow rubber pipe are respectively equipped with the installation position of interior expansion clip.During installation, at one end or two ends hollow rubber pipe is fixed on the inwall of drainage pipe.Or by means of flange, being arranged on the end face of the mouth of pipe, the direction of installation is installed according to water (flow) direction.
During draining, oblique circular cylinder rubber bag upwards shrinks resiliently deformable, forms larger drainage pipe; During non-return, oblique circular cylinder rubber bag is fitted downwards, fits, realize non-return with hollow rubber inner tube wall.
The beneficial effects of the utility model are,
Rubber check valve in the disclosed a kind of pipe of the utility model,
1, simple and compact for structure, simple installation, only needs valve to insert in the pipeline of corresponding bore, fixes, install and do not need change pipeline or structure structure, save a large amount of expenses in the front end of valve or rear end expansion clip or flange;
2, large-scale oblique circular cylinder rubber bag prior art can realize producing, and cannot produce at present for large-scale taper sheath, adopts the utility model oblique circular cylinder rubber bag can realize the use in large-scale pipeline;
3, in pipe, rubber check valve is owing to adopting oblique circular cylinder rubber bag, and compared to the conical surface in the past, scarf is more easily opened, and has extremely low loss of head, allows 100% aperture nearly, and valve is closely closed and can be avoided backward flow problem completely simultaneously.
4, long service life, intercepts waste water, waste gas is effective, realize real non-maintaining, quiet, atremia, employing rubber is made, and not easily gets rusty, greasy dirt common in resistance to sewage, practical, applied range, be specifically designed to sump, industrial sewage and city have stable political situation industry other field.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 be the utility model normality and non-return time structural representation;
Structural representation when Fig. 3 is the utility model draining;
In figure, 1, hollow rubber pipe 2, oblique circular cylinder rubber bag 3, interior expansion clip assembly department 4, seam 1, seam 26, adhesion section 7, laminating section.
Embodiment
In order to deepen, to understanding of the present utility model, to be described in further detail the utility model below in conjunction with drawings and Examples.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As Fig. 1, 2, shown in 3, rubber check valve in pipe, comprise valve cylinder and spool, valve cylinder is hollow rubber pipe 1, spool is oblique circular cylinder rubber bag 2, a part for oblique circular cylinder rubber bag 2 sack and hollow rubber pipe 1 Adhesion formation adhesion section 6, another part of oblique circular cylinder rubber bag 2 and hollow rubber pipe 1 are fitted and are formed section 7 of fitting, the girth of laminating section 7 is greater than the girth of adhesion section 6, the two ends inwall of hollow rubber pipe 1 is provided with interior expansion clip assembly department 3, the angle angle of the scarf of oblique circular cylinder rubber bag 2 and the center line of hollow rubber pipe 1 is 25 °-45 °, oblique circular cylinder rubber bag 2 sack is provided with seam 1, seam 1 is one-body molded with oblique circular cylinder rubber bag 2 sack, seam 1 matches with the seam 25 of hollow rubber inner tube wall.
During use, will be installed in waste discharge pipeline with the clip that expands in the hollow rubber Guan Jing of oblique circular cylinder rubber tape, structure in aggregates with pipeline, decrease the installing space of conventional discharge structure, do not need change pipeline or structure structure, save a large amount of expenses, simultaneously compact attractive in appearance again.
The sack of oblique circular cylinder rubber bag has sub-fraction and hollow rubber inner tube wall to be sticked together, the major part of sack not with the adhesion of hollow rubber pipe.But normality and closed time, fit together.The two ends of hollow rubber pipe are respectively equipped with the installation position of interior expansion clip.During installation, at one end or two ends hollow rubber pipe is fixed on the inwall of drainage pipe.Or by means of flange, being arranged on the end face of the mouth of pipe, the direction of installation is installed according to water (flow) direction.
