Abstract
The utility model discloses a water flow control valve comprising a valve body, a water inlet and a water outlet arranged in the valve body, a film, a pressure release hole and a sealing guide rod, wherein a passing hole is formed between the water inlet and the water outlet; one lower part of the film covers the passing hole and the other part of the film is positioned in the chamber of the water inlet; an upper chamber is formed above the film; the film is also provided with a micro-hole; one end of the micro-hole is communicated with the water inlet and the other end of the micro-hole is communicated with the upper chamber; one end of the pressure release hole is connected with the upper chamber and the other end of the pressure release hole is connected with the water outlet; and the sealing guide rod movably pushes against a water flow passage between the micro-hole and the pressure release hole. By adopting the technical scheme, the sealing guide rod can be pulled out and pressed down so as to change the water pressure on the film and to drive the film to open or close the water passage, thus realizing the aim of switching the water passage; and the operation is effort-saving as the structure of the sealing guide rod and the pressure release hole are adopted.
Description
Technical field
The utility model relates to a kind of mechanical type flow control apparatus for water, refers to the switch valve that utilizes concept of differential water pressures to control especially.
Background technique
Existing sanitaryware adopts rotary type ceramic spool and lifting and pulling type switching valve to control more.These spools all are directly to be pressed on the water (flow) direction, are subjected to the influence of variation in water pressure very big, can occur the phenomenon that requires bigger switching power to control under the situation of higher hydraulic pressure.The design people provides a kind of water flow control valve of new-type structure by the application to concept of differential water pressures, and very light and fast ground is controlled current under different hydraulic pressure, and this case produces thus.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of labour-saving mechanical type water flow control valve.
For solving the problems of the technologies described above, technical solution of the present utility model is:
A kind of water flow control valve comprises valve body, is arranged at water intake and water outlet, diaphragm, relief hole and sealing guide rod in the valve body; Form via hole between this water intake and the water outlet, a described diaphragm below part is placed on the via hole, and another part is positioned at the water intake chamber, the diaphragm top then forms upper chamber, also have micro hole on the diaphragm, this micro hole one end communicates with water intake, and the other end communicates with upper chamber; Described relief hole one end connects upper chamber, and the other end connects water outlet; On the mobilizable flow channel that is pressed between micro hole and relief hole of described sealing guide rod.
Described diaphragm top is provided with spring.
After adopting such scheme, the utility model can change the pressure that is added on the diaphragm by transfering to or depress the sealing guide rod, drives diaphragm and opens or closes the water route, thereby realize switch to the water route, owing to adopt relief hole and sealing guide rod, utilize hydraulic pressure to control keying, therefore comparatively laborsaving.

Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
What the utility model disclosed is a kind of mechanical type water flow control valve, as shown in Figure 1 to Figure 3, is preferred embodiment of the present utility model.This water flow control valve comprises valve body 1, is arranged at water intake 11 and water outlet 12, diaphragm 2, the spring 3 that is arranged on diaphragm 2 tops, relief hole 13 and sealing guide rod 5 in the valve body 1.Form via hole 14 between described water intake 11 and the water outlet 12, described diaphragm 2 below parts are placed on the via hole 14, another part is positioned at water intake 11 chambers, diaphragm 2 tops then form upper chamber 15, also have micro hole 21 on the diaphragm 2, these micro hole 21 1 ends communicate with water intake 11, and an end communicates with upper chamber 15.Described relief hole 13 1 ends connect upper chamber's 15, one ends and connect water outlet 12.Described sealing guide rod 4 is mobilizable to be pressed on the flow channel of 13 of micro hole 21 and relief holes.
The working principle of described diaphragm 2 is: control the switching of relief hole 13 by stretching of guide rod 5 of sealing, realize the variation of diaphragm 2 top and the bottom differential water pressures, thereby driven diaphragm 2 fluctuates, and plays the effect of switch water.As shown in Figure 5, diaphragm 2 lower zones comprise two part: S1 zone relative with diaphragm 2 that be water intake 11 chambers, the S2 zone relative with diaphragm 2 that be water outlet 12 chambers; And diaphragm 2 top pressurized zone S3=S1+S2.
The working procedure of described mechanical type water flow control valve is:
As Fig. 3 and cooperate shown in Figure 5, described sealing guide rod 5 moves down closes relief hole 13, water enters valve body 1 by water intake 11, enter by the micro hole on the diaphragm 2 21 in the upper plenum 15 on diaphragm 2 tops, water is assembled formation hydraulic pressure on diaphragm 2 tops, it is S3 that diaphragm 2 tops are subjected to the hydraulic pressure area, and it is S1 that the below is subjected to the hydraulic pressure area; Under the acting in conjunction of hydraulic pressure and spring force, diaphragm 2 is downward, closes water outlet 12.
Cooperate shown in Figure 5ly simultaneously as Fig. 4, sealing guide rod 5 moves up and opens relief hole 13, and the water that assemble on diaphragm 2 tops is at first discharged by relief hole 13, makes diaphragm 2 top releases, and it is S1 that diaphragm 2 belows are subjected to the hydraulic pressure area; Under the effect of intake pressure and overcome spring force, diaphragm 2 is upwards opened water outlet 12, and water flows to water outlet 12 from diaphragm 2 belows.
The setting of described spring 3 can be played auxiliary hydraulic pressure, make diaphragm 2 close the effect of water outlet 12.When this external pipeline hydraulic pressure deficiency caused upper chamber's 15 hydraulic pressure not enough, the effect of spring 3 can make diaphragm 2 be in normally off, prevented because of the not enough perennial draingage phenomenon that occurs of hydraulic pressure.
