Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing:
Embodiment: please referring to Fig.1 to Fig.3, a kind of venturi control valve, including venturi valve pipe 1 and venturi chamber 2,
Water stream channel is formed in venturi valve pipe 1, water stream channel side is equipped with duct and is connected to venturi chamber 2, venturi chamber 2
When water stream channel is normally intake, negative pressure is drawn the abdomen, and the venturi chamber 2 that water inlet is drawn the abdomen when stopping absorbs what venturi valve pipe 1 was flow backwards
Water.The upper and lower port of the water stream channel of venturi valve pipe 1 forms quick union 10.The venturi chamber 2 of the utility model be by
Bottom case 21 and gas-water separation piece 22 collapse cavity 200 made of cooperating, 22 other side of gas-water separation piece is equipped with gland 23, gland 23
It is fixedly connected to form pressure-bearing shell with 21 periphery of bottom case, pressure-bearing shell is also referred to as shell, shell two sides protruding portion 201, the protrusion of shell
Portion is specifically to be arranged on bottom case, and protruding portion is equipped with mounting hole.22 periphery of gas-water separation piece is equipped with upper and lower flange 221, bottom case
21 and gland 23 be equipped with the annular groove 203 that matches, gland 23 and bottom case 21 cooperate fixed gas-water separation piece 22, gland 23 with
Bottom case 21 is fixed by thermal capacitance or ultrasonic bonding.The pressure-bearing shell that gland 23 is formed with bottom case 21 can bear static pressure 0.5bar and arrive
5bar, water pressure of the dynamic pressure in 0.2bar to 16bar.Gas-water separation piece 22 is silica gel thin film in the utility model, more specifically
Food grade silicone film, bottom case 21, gland 23 are made of food-grade plastic cement material.The gland 23 of the utility model has pressure-bearing
Portion, pressure-bearing portion side are equipped with multiple reinforcing ribs 231.Reinforcing rib 231 can be set in qually spaced in gland pressure-bearing portion side, can also be with
It is laid out by design requirement, reinforcing rib 231 and gland 23 are integrally formed.
Such as Fig. 1 or Fig. 3, the bottom case 21, gland 23 and gas-water separation piece 22 of the utility model cooperatively form rectangular venturi
Chamber or round venturi chamber or semicircle or sector or other shapes venturi chamber, gland are equipped with stomata 232.
A kind of heater comprising the venturi control valve and heating inner liner, the setting of venturi control valve are being heated
On the inlet pipeline of liner, when heater water flowing, venturi chamber, which carries out absorbing hydraulic pressure, draws the abdomen, and venturi chamber carries out when water stops
Slow-absorbing liner water and pressure are overflowed for protecting liner to heat caused boiled water.
Venturi effect is utilized in the utility model, which shows restricted flow in the flow section by reducing
When, there is the phenomenon that flow velocity increase in fluid.Generally, this effect refer to can be generated near swiftly flowing fluid it is low
Pressure, to generate suction-operated, therefore, in the utility model venturi chamber 2 venturi valve pipe 1 water stream channel normally into
Negative pressure is drawn the abdomen when water.
The utility model is used for the control system of Feedwater Heater, wherein using food-grade plastic cement material shell, food
Grade silica gel thin film film is steam-water separation piece, is realized integrally molded using new-type improved ultrasonic mode, can bear static pressure
0.5bar to 5bar, water pressure of the dynamic pressure in 0.2bar to 16bar.When the system water flowing, which is carried out
Absorb hydraulic pressure draw the abdomen, when water stops the control system silica gel thin film carry out slow-absorbing liner water mode come transfer part liner water and
Pressure, protection liner heat caused boiled water and overflow.
The water control system of current household electrical appliance solves the hydraulic balance requirement of household heating electric appliance using Venturi effect,
But that there are small in size, pressure bearing ranges is small unobvious to perplex Venturi effect for the prior art, and then influences heating equipment.
