Abstract
The utility model relates to a hydraulic time-delay self-closing tap. The utility model has the technical proposal that a valve in a ball valve is connected with the middle part of a control rod; the back end of the control rod is provided with a handle, and the front end of the control rod is provided with a long slide groove; a convex block on a piston rod is embedded in the long groove, and the upper part of the piston rod is connected with a piston; the piston is arranged in a cylinder body; the upper part of the cylinder is provided with a valve cavity, the valve cavity is communicated with the cylinder body, and the inside of the valve cavity is provided with a one-way valve; the center of a circle of the one-way valve is provided with a small thin hole, the cylinder body is in parallel with a water outlet pipe, and the cylinder body and the water outlet pipe are mutually communicated with a tap water pipe; the outer shape forms an h shape. The utility model has the advantages of few parts, simple structure, good reliability, low cost, and water saving is especially suitable for public places.
Description
The utility model belongs to a kind of water and chews.
Present commercially available water-stopping self-closing water tap, mainly contain two kinds: a kind of is direct current formula water-stopping self-closing water tap, and the shortcoming of this water tap is: one is to use dangerously, and two are to use the cost height, and the 3rd, install inconvenient; Another kind is a mechanical type water-stopping self-closing water tap, and the part of this water tap is too many, and reliability is relatively poor, only because of the difference of a part, whole water is chewed can not be realized closing automatically sometimes.
The purpose of this utility model provides a kind of hydraulic pressure delay-self-closing water of above-mentioned deficiency of avoiding and chews.
The purpose of this utility model is achieved in that ball valve on the outlet pipe, valve in the ball valve is connected with the middle part of controlling rod, pull controlling rod up and down, valve is realized closing, the rear end of controlling rod is a handle, and the front end of controlling rod has microscler chute, and the projection on the piston rod embeds in the elongate slots, projection can slidably reciprocate in microscler chute, the top of piston rod connects piston, and piston is in cylinder body, and valve pocket is arranged at the top of cylinder body, valve pocket is communicated with cylinder body, one-way valve is arranged in valve pocket, little pore is arranged on the center of circle of one-way valve, cylinder body is parallel with outlet pipe, they and running water pipe are interconnected, and profile is h shape.Working principle is: pull handle downwards, and valve open, water flows out from water outlet, when pulling handle downwards, the front end of controlling rod raises up, and promotes piston stroking upward, cause that the pressure in the cylinder body increases, back down one-way valve, the water in the cylinder body flows into outlet pipe through valve pocket; When stopping to pull handle, water slowly flows into cylinder body by the little pore of one-way valve, and piston drives the front end bottom of controlling rod along with slowly descending, and handle raises up, and valve closing is finished self-closing task.
The utility model compared with prior art has that part is few, simple in structure, a good reliability, advantage such as with low cost, and it is specially adapted to the public place and uses, but using water wisely.
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing is a structural representation of the present utility model.
Ball valve 1 is arranged on the outlet pipe 4, valve 3 in the ball valve is connected with the middle part of controlling rod 2, pull controlling rod up and down, valve can be realized closing, the rear end of controlling rod is a handle, the front end of controlling rod has microscler chute 8, and the projection 7 on the piston rod 6 embeds in the microscler chute, and projection can slidably reciprocate in microscler chute.The top of piston rod is connected with piston 11, and piston is 12 li of cylinder bodies, and valve pocket 13 is arranged at the top of cylinder body, valve pocket is communicated with cylinder body, also in the chamber one-way valve 14 being arranged, little pore 15 is arranged on the center of circle of one-way valve, cylinder body is parallel with outlet pipe, and they and running water pipe 16 are interconnected, and profile is h shape.Working principle is: pull handle downwards, and valve open, water flows out from water outlet, when pulling handle downwards, the front end of controlling rod raises up, and promotes piston stroking upward, cause that the pressure in the cylinder body increases, back down one-way valve, the water in the cylinder body flows into outlet pipe through valve pocket; When stopping to pull handle, water slowly flows into cylinder body by the little pore of one-way valve, and piston drives the front end bottom of controlling rod along with slowly descending, and handle raises up, and valve closing is finished self-closing task.
Controlling rod be pointer 9 foremost, at pointer dial 10 is arranged in front, be fixed on the body, be used for showing the valve opening and closing time, the extension spring 5 of ining succession between controlling rod and body helps descent of piston.
Claims (2)
1, a kind of hydraulic pressure delay-self-closing water is chewed, there is ball valve (1) outlet pipe (4) lining, it is characterized in that: the valve in the ball valve (3) is connected with the middle part of controlling rod (2), the rear end of controlling rod is a handle, the front end of controlling rod has microscler chute (8), projection (7) on the piston rod (6) embeds in the elongate slots, the top of piston rod connects piston (11), piston is in cylinder body (12) lining, the valve pocket on the top of cylinder body (13), and valve pocket is communicated with cylinder body, one-way valve (14) is arranged in valve pocket, little pore (15) is arranged on the center of circle of one-way valve, and cylinder body is parallel with outlet pipe, and they and tap water (16) pipe are interconnected.
2, hydraulic pressure delay-self-closing water according to claim 1 is chewed, and it is characterized in that: controlling rod be pointer (9) foremost, at pointer dial (10) is arranged in front, be fixed on the body.
