The check valve of a drainage pipeline effectively solves the problems which is produced in a building drainage piping system that the drainage reflows, pest such as cockroaches and the like enter into a building through the drainage pipeline, odor enters into the building along the building drainage and the like.
Description
Technical field
The invention belongs to the accessory field of building drainage pipeline, particularly relate to a kind of flap valve of drainage pipe.
Technical background
At present the building drainage pipeline system often occurs that insects such as draining backflows, cockroach enter building by drainage pipe and foul smell enters phenomenons such as building along drainage pipe, brings very big inconvenience to people's life.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, design a kind of simple in structure and prevent that effectively insects such as draining backflow, cockroach from entering building, foul smell enter problems such as building along drainage pipe draining by drainage pipe and preventing valve, thereby reach the purpose of improving the quality of living.
In order to realize the foregoing invention purpose, the technical scheme of employing is as follows:
A kind of flap valve of building drainage pipeline, comprise valve body, spool, nut, described valve body comprises the inlet segment that is provided with water inlet, the draining section that is provided with delivery port, and the valve pocket between inlet segment and draining section, the top of valve pocket is provided with installation opening, nut is connected with valve body by this installation opening, and described spool is arranged at the passage port that inlet segment and valve pocket join.
The present invention is provided with spool by the passage port that inlet segment and valve pocket at valve body join, when can or not have flow at underfed, spool blocks passage port, avoided the backflow of sewage, and insect enters inlet segment, is arranged at the valve pocket top by nut again, by the screw thread that the external surface at cylindric installation opening is provided with and nut coincide, by being threaded, can spool being installed conveniently and playing the effect whether the inspection spool lost efficacy and changed maintenance.
In the technique scheme, described inlet segment becomes the obtuse angle with the port plane longshore current body direction that valve pocket joins with the valve body bottom.Even time spent spool and valve pocket obtuse angle assembling at an angle, can utilize the deadweight of spool to contact, thereby seal the inlet segment of valve body and the port that valve pocket joins, reach sealing function with valve interior wall, thereby do not need other closing means to simplify product structure, save cost.
Further, the bottom of described valve body is stepped, and described ladder corner is arranged at the passage port that inlet segment and valve pocket join, and the bottom of inlet segment is higher than the bottom of valve pocket.By stepped setting, make that on the one hand a small amount of sewage that residues in valve body draining section can't reflux to inlet segment, and on the other hand, when spool seals the port that inlet segment and valve pocket join under the effect of self gravitation, the port lower end also had a downward active force, guaranteed the compactness of sealing, effectively prevented owing to the gap between spool and the port causes a small amount of phenomenon that refluxes.
Spool of the present invention comprises two parts, main body and installation portion, main body is circular thin piece, the upper end of main body is provided with the assembling hook that is overlapped on valve body installation opening upper limb, as installation portion, the assembling hook can directly be overlapped on the upper limb of installation opening, also can be provided with and assemble the fitting recess that elegant jessamine closes at the installation opening upper limb of valve body, the assembling fastener is in fitting recess, described assembling hook and main body junction also are provided with " V " type groove, and " V " type groove can be used as the material reducing part of saving material on the one hand, on the other hand, " V " type groove makes that the junction of assembling hook and spool main body is thinner, make things convenient for spool under the impact of flow, to break away from the port that valve inleting water section and valve pocket join as early as possible, can not hinder flowing of fluid, and reduce when opening spool thrust requirement draining, and when needs sealing port, also can the fastest realization sealing.
The main body of spool of the present invention is made up of rubber bodies and the embedded metal medium of rubber bodies.The rubber spool can play the dirty sealing function of antirust life, and it then is to improve the intensity of spool and make spool have the sagging naturally sealing port of enough weight that spool is embedded in metal medium.
Preferred version of the present invention also includes gasket seal, and described gasket seal is arranged between installation opening upper limb and the nut.Realize the sealing that is connected between nut and the valve body by gasket seal, make that to prevent that foul smell from flowing into the effect of building better.
Also be provided with packing ring between described gasket seal and the nut.Packing ring can be realized contacting more evenly between nut and the gasket seal, has promoted the sealing performance that connects, and has alleviated the impaired distortion of gasket seal in the use to a certain extent.
By such scheme, the present invention effectively solves insects such as draining backflow that the construction drainage pipe-line system occurs, cockroach and enters building, foul smell by drainage pipe and enter problems such as building along drainage pipe.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is an enforcement schematic diagram of the present invention.
The specific embodiment
The present invention is further illustrated below in conjunction with accompanying drawing.
Structural representation of the present invention is shown in accompanying drawing 1, accompanying drawing 2, comprise valve body 1, spool 2, gasket seal 3, packing ring 4, nut 5, valve body 1 comprises the inlet segment 12 that is provided with water inlet 11, the draining section 14 that is provided with delivery port 13, and the valve pocket 13 between inlet segment 12 and draining section 14, the top of valve pocket 13 is provided with installation opening 15, nut 5 is connected with valve body 1 by this installation opening 15, and also being placed with gasket seal 3 and packing ring 4 between nut 5 and installation opening 15 upper ends respectively, 2 of described spools are arranged at the passage port that inlet segment 12 and valve pocket 13 join.
Inlet segment 12 becomes the obtuse angle with the port plane longshore current body direction that valve pocket 13 joins with valve body 1 bottom.The bottom of valve body 1 is stepped, and described ladder corner is arranged at the passage port that inlet segment 12 and valve pocket 13 join, and the bottom of inlet segment 12 is higher than the bottom of valve pocket 13.Described spool 2 main bodys are circular thin piece, and the upper end is provided with the assembling hook that is overlapped on installation opening 15 upper limbs, and described assembling hook and main body junction also are provided with " V " type groove.
Enforcement schematic diagram of the present invention as shown in Figure 2, wherein A is the duty when not having draining, spool 2 is under the reusing of self gravitation, seal the port of valve body 1 inlet segment 12 and valve pocket 13, prevent insects such as sewage backflow, cockroach by drainage pipe enter building, foul smell enters building etc. along drainage pipe.
Duty when B is draining, spool 2 breaks away from port under the impact of current, do not influence the proper flow of current.
C is the duty when blocking sewage backflow, and during sewage backflow, spool 2 blocks port, makes sewage can't flow into inlet segment 12.
