Abstract
The utility model provides a pressure difference low-position cistern feed valve for a closet. The pressure difference low-position cistern feed valve for a closet has a main structure which is changed from a lever type of the prior art into a pressure difference type. Concretely, a water inflow body is arranged in the center of the pressure difference low-position cistern feed valve for a closet, and a valve body is arranged in the upper end of the water inflow body, and a cavity of the valve body is provided with a valve core; a cover presses on the valve core, one end of a lever is hinged with one end of a screw rod, and the other end of the lever contacts with a control hole B; the other end of the screw rod is hinged with a float bowl, a casing tube is sheathed out of the water inflow body, and a control hole A is arranged in the valve core. The pressure difference low-position cistern feed valve for a closet greatly overcomes the disadvantages of large volume, poor sealing performance, etc. in the existing lever type low-position cistern feed valve, and the pressure difference low-position cistern feed valve for a closet greatly enhances sealing reliability.
Description
The utility model proposes the differential low cistern inlet water tank of a kind of water closet, belong to the low cistern for closet bowl accessory.
Prior art, as the 7301 Lever type inlet valves of selling on the market, its structure is by utilizing a long arm of force, utilize its lever principle, spool is sealed water intake, reaching the amount of water inlet in the control water tank.Its defective is that volume is big, because because lever often is in stress, so the lever distortion is easy, will certainly influence the effect of sealing like this, reduces the reliability of water tank water intake valve seal.
The purpose of this utility model is to overcome the defective of above-mentioned existence, proposes a kind of new seat and makes the differential low cistern inlet valve of device.
Technical solution of the present utility model: the water inlet main body is located at valve central authorities, valve body is contained in the into upper end of water main body, the cavity of valve body is equipped with spool, lid is pressed on the spool, one end of lever and an end of screw rod are hinged, and the other end of lever contacts with control hole B, and the other end and the floating drum of screw rod are hinged, casing pipe sleeve is in the outside of water inlet main body, and control hole A is located on the spool.
Accompanying drawing 1 is a structural representation of the present utility model.
Among the figure 1 is adjusting screw rod, the 2nd, presses mother, the 3rd, lever, the 4th, and lid, the 5th, rubber spool, the 6th, valve body, the 7th advances water main body, the 8th, and floating drum, the 9th, sleeve pipe, A are that control hole, B are control holes.
Below in conjunction with its working procedure of description of drawings:
During water inlet, because cistern water level progressively improves, floating drum 8 rises thereupon, when waiting to arrive certain water level (by manually given), seals control hole B by an end of lever 3.At this moment, under ductwork pressure water by control hole A penetrate into cover 4 and elastomeric plastics spool 5 between hydroecium, make this chamber pressure increase to ductwork pressure because the chamber area is greater than valve body 6 water intake areas, therefore, below elastomeric plastics spool 5 pressed to, sealed drain opening.Floating drum 8 slides up and down in sleeve pipe 9 outsides, and the floating drum body is less, and water shutoff pressure is also very little.Design one heliconid outside water inlet main body 7 is used current not directly not downwards, but is moved into water main body circulation, reduces the flow velocity of water, and its noise reaches 47 decibels (GB is defined as 60 decibels).
The utility model characteristics: volume is little, and good airproof performance is reliability and durability.
