Abstract
The utility model provides a sealing type water valve, which is composed of a valve body, a sealing ring, an upper and a lower rubber diaphragms, and a water inlet pipe. The utility model is characterized in that the valve body is formed by that an upper half body and a lower half body are in screw connection, a rubber ring with strong elasticity is used as the sealing material between the two half bodies, and the upper and the lower rubber diaphragm are used as the control device of a water inlet and outlet valve in the valve body. Hence, the utility model has the characteristics that good tightness, simple structure, low cost, long service life, convenient installation and maintenance, etc.; the shape of the utility model can not be changed easily.
Description
The utility model relates to water system, particularly a kind of sealed type water valve.
At present, be used for the valve control of water tank, generally adopt float valve drive mechanical lever to control.Its working principle is: ball float lifting with the height of water level in the water tank, and when water level increased, ball float raise simultaneously, when reaching a certain value, protruding plug before the other end spiral pin compressing water outlet of travel(l)ing rest, protruding rubber washer beyond the Great Wall covers water outlet, has closed current.When drawdown, ball float descends thereupon, and the support spiral pin is no longer oppressed protruding plug, and rubber washer leaves water outlet, and water flows out again.The advantage of this float valve is firmer practicality.But there is following shortcoming in it: 1, because constituent elements is many, and complex structure, volume is excessive, the installation and maintenance trouble; 2, often under water because of this float valve, and its movable part is fragile, therefore can only be with stainless metallic material manufacturing, thereby manufacture cost is also high; 3, ball float pole is subjected to hydraulic pressure for a long time, and easy deformation causes protruding plug compressing tightly not leaked; 4, after float valve used a period of time, because long-term work is at pressured state, as often not overhauling, not only hollow float broke easily, and function out of hand, and also easy-to-rust of its adjusting pin and protruding plug cause leaking because of adjusting and being not closed completely.
The purpose of this utility model provides a kind of self hydraulic pressure that utilizes, and the valve by upper and lower rubber diaphragm separator is controlled can reduce production costs, water-saving sealed type water valve.
Technical solution of the present utility model is: the sealed type water valve, by valve body 1, seal ring 5, go up rubber diaphragm separator 7, down rubber diaphragm separator 10, go into water channel 12 and constitute.Described valve body 1 is to be made of through being threaded upper semi-body 2 and lower semi-body 8, has the function of regulating water level by adjusting screw thread.The joint employing elasticity of upper body and lower body rubber band 5 is preferably made sealing material.The last rubber diaphragm separator 7 that is arranged in the valve body is fixed on the spill inwall of upper semi-body 2, and following rubber diaphragm separator 10 is fixed on the spill water outlet tube wall of lower semi-body 8, and its center projection contacts into watercourse port, plays the switch current.This valve body is divided into inside by upper and lower rubber diaphragm separator and has hydroecium 3 and air chamber 9 two-part.The outer surface of upper that is positioned at valve body is provided with two water injection holes 4 and an exhaust port 15.Its underpart outer surface is provided with two osculums 13, and its bottom also is provided with an air outlet hole 16.
The utility model has the advantages that: 1, simple in structure, cost is low, and the mass activity parts can adopt low-value materials making such as plastics, and not yielding, the life-span is long.2, owing to adopt upper and lower rubber diaphragm separator as the water-inflow and drain valve door, so good seal performance.3, valve body itself can arbitrarily be adjusted, and cistern water level need not be established the adjustment spiral pin in addition.Since lower diaphragm plate with go into watercourse port and set a fixed gap, therefore secondary water flow size no matter all can flow into water tank smoothly by rubber diaphragm separator down and the gap of going between the watercourse port.
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is a sectional view of the present utility model;
Fig. 2 is the A-A view of Fig. 1.
As shown in the figure: this valve body is made of upper semi-body 2 and lower semi-body 8, and last lower body both can be integrated through being threaded, and also can play the adjustment spiral pin and be used for regulating water level.Adopt the strong rubber band 5 of elasticity to make sealing material between about the valve body.Be provided with upper and lower rubber diaphragm separator in the valve body, last rubber diaphragm separator 7 is fixed on the spill inwall of upper semi-body, and valve inner is separated into hydroecium 3 and air chamber 9 two-part.Top is hydroecium, and the bottom is an air chamber.Following rubber diaphragm separator is fixed on the spill water outlet tube wall of lower semi-body, and the center projection of its barrier film contacts into watercourse port, plays the effect of switch current.Be provided with two water injection holes 4 on the appearance top of valve body, its underpart is provided with two osculums 13, and secondary water flows into water tank by osculum.The bottom is provided with an air outlet hole 16, so that can move up and down when making down the rubber diaphragm separator pressurized.The top that is positioned at valve body is provided with an exhaust port 15 that communicates with the water plug.
Its working principle is: secondary water enters water tank through the osculum 13 of going into water channel and water outlet, and when cistern water level was elevated to a water level, water just entered hydroecium from the water injection hole of valve body.When the hydraulic pressure of hydroecium raises, the inner pressure that produces of water valve, last rubber diaphragm separator core pressurized and descending, rubber diaphragm separator under the compressing simultaneously, capping go into watercourse port, thereby closed current.The water tank of this moment is state of rest, and after the water in the water tank was discharged from, the water of hydroecium was also discharged through osculum thereupon in the valve body, and last rubber diaphragm separator loses pressure and sets back.Following rubber diaphragm separator pine immediately makes secondary water flow to water tank again from going into watercourse port.
