Abstract
The utility model relates to a safety water tap for running water. The utility model is composed of a shell body, a sealing mechanism along the water pressure direction, an operating mechanism and an opening and closing mechanism, wherein, the sealing mechanism along the water pressure direction is composed of a valve core cover, a spring, a water outlet hole plate, etc; the operating mechanism is composed of a handle, a rotating shaft, a torsion spring, etc; the opening and closing mechanism is composed of a switch push rod, an oblique tooth push barrel, a positioning wave-shapes tooth barrel, a spring, etc. The utility model has automatic closing when the water is not provided and no water leakage, guarantees the safe water using function that an end cover is opened and taken out to repair the failure of the water without flowing when the opening and closing mechanism generates failure or is damaged, etc., and obtains the goals of the water resource and the energy saving.
Description
The utility model proposes a kind of safe water that is used for tap water and chew (water tap).
The purpose of this utility model provides and a kind ofly can guarantee safe water, with the jettison gear of the conserve water resource and the energy.
The present water tap that generally uses, often be not closed completely and leak, around valve rod, emit water when discharging water, open anhydrous forget again close, after walking, the people comes water again, cause the waste of long-time a large amount of flowing water, even cause water logging house damage product, draining to downstairs, neighbours cause bothersome problems such as dispute.
Through the Searches of Patent Literature, for addressing these problems, existing many relevant model utilitys propose, compare with the utility model, concrete structure difference, technical functionality also have difference, as the safe water tap that China's patent ［ 21 ］ application number 88219189.6 proposes, has only the function that to open when anhydrous.
Technology contents of the present utility model is: this safe water is chewed the housing of being made up of valve body (16), end cap (18); The direction of the pressure downstream closing means of forming by cartridge cover (11), spring (10), water outlet orifice plate (13), seal rubber pad (12) O-ring seal (14), back-up ring (15); The operating device of forming by handle (1), rotating shaft (4), torsion spring (2), position limit pin (3), O-ring seal (5); Switching mechanism four parts of being made up of switch push rod (17), helical teeth pushing cylinder (7), location waveform tooth tube (6), spring (8), (9) constitute.It is characterized in that having one to press the direction closing means downstream at inlet segment, can play the function of stop valve, switching mechanism is out of order or when damaging, and opens end cap and takes out and repair also not water outlet; In the mechanism that water exit end has a pressure that utilizes water to realize opening, close, adjust the water yield and close automatically when anhydrous.
Fig. 1 is the longitudinal sectional drawing of a kind of concrete structure of the utility model.
Fig. 2 is the side view of other part of a location waveform tooth tube (6) in the utility model concrete structure.19. the waveform tooth, 20. feather keys, 21. cylindrical shells.
Below with reference to Fig. 1, describe concrete structure of the present utility model and working condition in detail.
When discharging water, with hand clockwise direction handle with sleeve (1), drive rotating shaft (4) and switch push rod (17) and rotate together, promote helical teeth pushing cylinder (7) and move down, promote cartridge cover (11) simultaneously and open water outlet orifice plate (13).At this moment, current enter the hole of helical teeth pushing cylinder (7) bottom by the hole of water outlet orifice plate (13), make the bottom of locating waveform tooth tube (6) increase the pressure of water, block switch push rod (17), it is positioned on the position, hand leaves handle (1) and also can not close.Water flows into valve pocket the hole from the wall of helical teeth pushing cylinder (7) garden, chews outflow from water outlet.This process is finished at instantaneous time.On location waveform tooth tube (6) several waveform teeth are arranged, it is sleeved on the inside of helical teeth pushing cylinder (7), can slide up and down, can not left-right rotation, and play position-sensing switch push rod (17) and select the water yield.
When closing, with hand counter clockwise direction handle with sleeve (1), drive the semicircle flank of tooth slip of switch push rod (17) along location waveform tooth tube (6), forward position limit pin (2) always to and locate.Under the force action of the pressure of water and spring (9), (10), helical teeth pushing cylinder (7) and cartridge cover (11) move up simultaneously, and cartridge cover (11) just stops water outlet with water outlet orifice plate (13) sealing.
When in the pipeline when anhydrous, handle with sleeve (1) is pushed cartridge cover (11) open, does not flow through from water outlet orifice plate (13) because of there being water, and the bottom of location waveform tooth tube (6) does not have the pressure of water, can't stop switch push rod (17), and hand leaves handle (1), just closes automatically.As long as anhydrous in the pipeline, it can't be parked in the state of discharging water.
Feature of the present utility model has guaranteed the safety of water, can not run and emit the phenomenon of leaking, and reaches the purpose of the conserve water resource and the energy.
In order to guarantee the reliability of the utility model function, increase the service life, shell will be cylinder iron or the Cu alloy material manufacturing, and preferably chromium plating makes it antirust and attractive in appearance.The shell moulding can be designed to various novel shape, to beautify family environment.The inlet segment closing means is a key position of the present utility model, use not corrosion, ageing-resistant made.All springs all will be used copper elastic material, and seal ring, pad will be used ageing-resistant made.Helical teeth pushing cylinder (7) and location waveform tooth tube (6) will be used the nylon manufacturing, to reduce friction factor.Miscellaneous part can be with engineering plastics manufacturings such as nylon.
Claims (3)
1, the utility model is that safe water is chewed, and it is characterized in that the housing of being made up of valve body (16), end cap (18); The direction of the pressure downstream closing means of forming by cartridge cover (11), spring (10), water outlet orifice plate (13), seal rubber pad (12), O-ring seal (14), ring washer (15); The operating device of forming by handle (1), rotating shaft (4), torsion spring (2), position limit pin (3) O-ring seal (5); Switching mechanism four parts of being made up of switch push rod (17), helical teeth pushing cylinder (7), location waveform tooth tube (6), spring (8), (9) constitute.
2, safe water according to claim 1 is chewed, and it is characterized in that pressing the direction closing means downstream, is positioned at the inlet segment of housing.
3, safe water according to claim 1 is chewed, and it is characterized in that switching mechanism, is positioned at the water exit end of housing.
