Description
Technical Field
The utility model relates to a leak protection water structure of pressure rinse-system aeration valve.
Background
At present, pressure flushing water tank toilets utilizing compressed air to flush are available in the market, an air supplementing valve is generally required to be installed on a water inlet valve of the flushing system, most of the air supplementing valves are structurally characterized in that a side cavity is arranged beside a water inlet waterway, a one-way valve structure is installed in the side cavity, and when water enters, the one-way valve is opened to synchronously suck air in atmospheric pressure into the system so as to realize air supplement in a pressure tank body; when the water inlet valve stops water inlet, the one-way valve needs to be capable of sealing water to prevent water from leaking into air. However, one problem encountered in practice with this arrangement is the high risk of water leakage from the check valve. Because the general structure of this kind of tonifying qi check valve is the sealed stagnant water of rubber duckbill or a rubber buffer, at first the rubber comes product self to age easily and appear stagnant water badly, secondly like the mouth position of this kind of product of duckbill be a natural closed gap need use the cutter frock to die-cut, the production very easily produces the microcrack and leads to leaking water that bigger crackle appears after leading to long-time use, and in case leak water, the serious consequence of bringing is the unable normal work of whole flushing system, can lead to the water to leak to the floor to the more serious problem that brings to no water tank closestool.
Disclosure of Invention
In order to solve the technical problem, an object of the utility model is to provide a leak protection water structure of pressure rinse-system gulp valve.
The utility model discloses a following technical scheme realizes:
the utility model provides a leak protection water structure of pressure rinse-system gulp valve, includes the body that has an air inlet, be provided with a check valve in the air inlet, air inlet department is provided with the turning joint that one end links with the body, be provided with the passageway that links with the air inlet in the turning joint, be provided with a notch portion in the other end of turning joint, the turning joint other end hookup has a lid, be provided with the opening that can link with the passageway on the lid, be provided with one in the notch portion and open and close open-ended stopper.
In the embodiment of the utility model provides an in, opening week portion is provided with the bulge loop towards notch portion, the bulge loop can realize the open-ended shutoff with the sealed cooperation of stopper.
In the embodiment of the present invention, the check valve is a duckbill check valve.
The utility model discloses a leak protection water structure of pressure rinse-system gulp valve has following beneficial effect: 1. the service life of the air supply valve group is greatly prolonged, and water leakage is avoided in use; 2. the closestool without the water tank is a key safety guarantee, and the water leakage event is avoided.
Drawings
In order to more clearly illustrate the technical solution of the present invention, the drawings needed for the description of the embodiments or the prior art will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art that other drawings can be obtained according to the drawings without creative efforts.
Fig. 1 is a schematic diagram of state one of the present invention.
Fig. 2 is a schematic diagram of state two of the present invention.
Fig. 3 is an exploded view of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
Referring to the drawings of the specification, a water leakage prevention structure of an aeration valve of a pressure flushing system comprises a body 10 with an air inlet 11, a one-way valve 20 is arranged in the air inlet, a bent joint 30 with one end connected with the body is arranged at the air inlet, and in one use: the elbow joint can be a 90-degree joint, the other end of the elbow joint faces upwards, a channel 31 connected with the air inlet is arranged in the elbow joint, a notch part 32 is arranged in the other end of the elbow joint, the other end of the elbow joint is connected with a cover body 40, an opening 41 capable of being connected with the channel is arranged on the cover body, and a plug 50 capable of opening and closing the opening is arranged in the notch part. The utility model discloses in normal use, the stopper is located the below of notch portion under the condition of dead weight, stopper this moment can not contact the cooperation with the opening, gas under this state can follow the opening and go on the passageway and enter into this internally from the check valve, realize the function of tonifying qi, but when the check valve leaks, water can follow the check valve and flow backward to turn the shape and connect in, when water reachs a certain amount, water can be with stopper up pushing away, seal the opening, water can not flow to the outside in this time, avoid the production of the incident of leaking.
The utility model discloses an embodiment, opening week portion is provided with the bulge loop 42 towards notch portion, the bulge loop can realize the open-ended shutoff with the sealed cooperation of stopper, and when water up pushed away the stopper, stopper and bulge loop are direct closely to be laminated, make water can not flow from the opening.
In one use, the one-way valve is a duckbill-type one-way valve.
While the foregoing description shows and describes the preferred embodiments of the present invention, it is to be understood that the invention is not limited to the forms disclosed herein, but is not intended to be exhaustive or to exclude other embodiments and may be used in various other combinations, modifications, and environments and is capable of changes within the scope of the inventive concept as expressed herein, commensurate with the above teachings, or the skill or knowledge of the relevant art. But that modifications and variations may be effected by those skilled in the art without departing from the spirit and scope of the invention, which is to be limited only by the claims appended hereto.
