Abstract
The utility model discloses a self-closing typed water tap, which is composed of a valve body (1), a valve body cover (2), a valve body (3), a spring (4) arranged on a valve rod, a valve plug (17), etc. The self-closing typed water tap is characterized in that the valve rod is sheathed in the valve body cover and the valve body and can make axially motion; the valve body cover is screwed into and connected with the valve body by screw threads. Pressing down a pressing cap (12), the valve plug move downwards as the valve rod and water flows out of the water inlet hole (31) of the valve body. Removing off a hand, under of the tension of the spring and the outward pressure of tap water, the valve plug is folded up with the water inlet hole of the valve body. The self-closing function of the self-closing typed water tap avoids energy waste caused by forgetting turning off a water tap. The utility model has the advantages of low cost, convenient installation and maintenance, water saving, favorable water leakage-proof effect, etc.
Description
The utility model relates to a kind of self-closing water tap, belongs to the hot-water heating device.
In the prior art, have a kind ofly by the spring self-closing water tap of foot treadle by a series of pull bars, lever, because loosely organized, numerous and diverse, transmission distance, thereby functional reliability is poor.Chinese patent ZL93237120.5 discloses a kind of delayed self-close water tap, utilizing depression bar to drive on the piston moves, reach the purpose that time-delay is supplied water, its deficiency is: main working parts---the surface of contact distortion easy to wear of piston, spring in the piston is under water, perishable, so sealing is poor, easily leaks.
The utility model aims to provide a kind of simple and reasonable, self-closing water tap that water-saving result is good.
Fig. 1 is the structural profile schematic representation of self-closing water tap, and Fig. 2 is the structural profile schematic representation of valve rod, and Fig. 3 is the structural profile schematic representation of valve body and body cap.
Describe structure of the present utility model and annexation in detail below in conjunction with accompanying drawing.
The utility model is made up of valve rod (1), body cap (2) and valve body (3) three parts, and valve stem casing is in body cap and valve body, and body cap is to be threaded into the connection valve body.
Valve rod (1) is the solid metal body, can be divided into five parts: valve rod (1), valve rod upper end (11), valve stem tip (13), valve rod lower end (15) and valve stem end (10).Valve rod (1) is gone up cover one spring (4), and spring (4) is a helical spring, and it and valve rod (1) and body cap (2) are complementary; The external diameter of valve rod upper end (11) is big than valve rod (1), is beneficial to pressure spring (4), prevents that spring (4) from ejecting; Valve stem tip (13) has outside thread, installs one and is beneficial to pressure cap (12) that hand pushes and the fixing cheese head screw of pressure cap (14); The external diameter of valve rod lower end (15) is littler than valve rod (1), the ring washer (16), the packing ring (18) that valve plug (17) are installed and mate with valve plug (17); Valve plug (17) is the rubber valve plug of a layer cross section cone, and the conical bore aperture of its external diameter and valve inleting water hole (31) matches, and plays airtight effect; Valve stem end (10) has outside thread, can supply nut (19) to screw in fixedly valve plug (17).
Body cap (2) is the open circles tubulose, its internal diameter and valve rod (1) shape is complementary, in the contact segment of body cap (2) inwall and valve rod (1), promptly spring (4) below, be provided with O-ring seal (21), use compresses bung flange (22) extruding fixing seal cushion rubber (21) and is close to valve rod (1), prevent that tap water from along the outside seepage of valve rod (2), like this, both having avoided the tap water filter loss, make spring avoid etch again, increase the service life.
Valve body (3) is the part that connects water supply line and water outlet, and there is a conical valve inleting water hole (31) in its stage casing, flows out the face that dams that provides for valve plug (17) stops water.When hand connect pressure pressure cap (12), valve rod (1) moved down and has compressed spring (4), and made the valve plug (17) that is fixed in the valve rod lower end along with moving down, so tap water flows out by valve inleting water hole (31); After hand left, valve rod (1) moved up under the elastic force effect of spring (4), had been with on the valve plug (17) and was moving, and the conical surface of valve plug (17) is close to till the valve inleting water hole (31), and water is intercepted, and stopped outflow.Body cap (2) is added with seal ring (32) with the joint of valve body (3).
The utility model can connect general faucet body water outlet, also can adopt water tank to replace faucet body, the water outlet of design water tank is less than the valve inleting water hole, and like this, inflow is greater than water-outlet quantity, water tank holds full water very soon, after hand leaves pressure cap, move the obstruction current on the valve plug, and jar interior water just is enough to supply a period of time, can supply the both hands washing articles, reach the purpose that time-delay is supplied water.
The utility model has the advantages that: structure and principle are simple, utilize the tension force and the tap water of spring to reach the airtight effect of cutting off the water supply to the pressure that leaks, the outside pressure of tap water is become the active force that makes full use of, make that the cross section in valve plug and valve inleting water hole is tightr, water-tight.This cost of goods manufactured is low, and water-saving result is good, and installation and maintenance are convenient, are specially adapted to public places such as school, factory, station, harbour, have good practicability.
