Abstract

A rubber check valve has a valve (1), the valve (1) has an inlet (2), and an outlet (3), the valve is characterized in that the valve (1) is provided with a rubber core (4), the inner side wall of the rubber core (4) is appearing the ring shape, the top is connected with the input (2), the bottom is closed connected with a rubber plate shape nozzle valve (5) that is arranged slantingly.

Description

The rubber safety check

Technical field:

The utility model relates to a kind of water and returns valve, and especially a kind of alternative S bend pipe is installed in the drainage pipe, and is simple in structure, cheap, can effectively prevent to return on the peculiar smell, cockroach, mosquito visit one house after another and winter the S bend pipe produce the rubber safety check of freezing phenomenon.

Background technique:

At present, all be provided with the S bend pipe basically in various indoor drainage pipes, the inertia that weight such as the impulse force of sewage (waste water), dirt produce is broken through the S bend pipe to sewerage with sewage, dirt.Usually have part of contaminated water and accumulate on the S bend pipe, play to stop on the sewerage peculiar smell and return (deodorization) or prevent that cockroach, mosquito from scurrying the effect at family.But the moment of flowing through the S bend pipe at large amount of sewage can produce certain vacuum in drainage pipe, the sewage on the S bend pipe is taken away, and the peculiar smell in the sewerage returns promptly to indoor, pollutes indoor environment, propagates various germs; Cockroach in drainage pipeline, mosquito etc. also can scurry into indoor by drainage pipe simultaneously; During winter, also can cause impeded drainage, need the more human and material resources dredging pipeline of cost, bring worry to the people owing to low temperature makes the sewage that is stored in the S pipe bent position freezing; In addition, the S bend pipe is installed also need be taken bigger space, trouble is installed.

Summary of the invention:

The utility model is in order to solve existing in prior technology the problems referred to above, provide a kind of alternative S bend pipe to be installed in the drainage pipe, simple in structure, cheap, can effectively prevent to return on the peculiar smell, cockroach, mosquito visit one house after another and winter the S bend pipe produce the rubber safety check of freezing phenomenon.

Technical solution of the present utility model is: a kind of rubber safety check, valve body 1 is arranged, and import 2, outlet 3 are arranged on the valve body 1, be built-in with rubber spool 4 at valve body 1, the sidewall of described rubber spool 4 ringwise, upper end and import 2 are joined, the lower end is closed and join with the tabular valve nozzle 5 of the rubber that is obliquely installed.

The tabular valve nozzle 5 of described rubber is 30～45 degree with the tilt angle of Vertical direction.

The utility model is to make with elastomeric rubber, and alternative S bend pipe is installed in the drainage pipe, and the big I of its valve nozzle changes with current, and when in the spool water being arranged, the impulse force of water is opened tabular valve nozzle and flow in the sewerage; When in the spool when anhydrous, the tabular valve nozzle of rubber can rely on the elasticity of rubber and close, stop on the peculiar smell in the sewerage and return to indoor, with fresh air in the holding chamber, prevent bacteria-travelling, can prevent also that simultaneously in-line arrangement water pipes such as cockroach, mosquito from scurrying problems such as family and S bend pipe be freezing, remove the worry of therefore bringing to the user.The utility model is simple in structure, cheap, be easy to install, and the pipeline of available any material connects, without screw thread, tackiness agent, only import, outlet and drainage pipe are tightened and get final product with clip, do not seep water, air tight, safe and reliable, can save the installation time, the space.

Description of drawings:

Fig. 1 is the utility model embodiment's a structural representation.

Fig. 2 is the A-A view of Fig. 1.

Embodiment:

Below in conjunction with description of drawings embodiment of the present utility model.As shown in Figure 1, 2: a kind of rubber safety check, be to make valve body 1 with rubber, import 2, outlet 3 are arranged on the valve body 1, be built-in with rubber spool 4 at valve body 1, the sidewall of described rubber spool 4 ringwise, the upper end joins with import 2, and the lower end is closed and join with the tabular valve nozzle 5 of the rubber that is obliquely installed, and the tilt angle of the tabular valve nozzle 5 of rubber and Vertical direction is 30～45 degree preferably.

If make, then can be applicable in the industry equipment such as refrigeration grade of rubber such as acidproof, alkaline-resisting.

Claims

1. rubber safety check, valve body (1) is arranged, import (2), outlet (3) are arranged on the valve body (1), it is characterized in that: be built-in with rubber spool (4) at valve body (1), the sidewall of described rubber spool (4) ringwise, the upper end joins with import (2), and the lower end is closed and join with the tabular valve nozzle of the rubber that is obliquely installed (5).
