Product description
Parameters
pic
Brass or stainless steel valve body, float and valve core are made of brass for high temperature resistance, high pressure resistance and corrosion resistance.
Differential pressure working principle, only inhale but not exhaust, flexible opening and closing;
No need for manual operation, automatic inhalation action, sensitive replenishment, sufficient air intake.
The internal sealing parts are all tapered hard seals, which makes up for the shortcomings of the previous products that used plastic or rubber rings to seal;
There is a slight noise when the float moves, and no sound can be heard from one meter away; no environmental noise will be formed.
It has the advantages of simple structure, convenient installation and operation, long service life and low maintenance cost.

The working principle of this patented product is when drainage is needed. The discharged water enters the internal drain trough through the upper drain of this valve. Under the action of water gravity, the sealing flap in the valve body is automatically opened so that the water is discharged into the sewer through the drain; when the water is emptied, the sealing flap no longer bears the drain Pressure, at this time, the automatic flap returns to the original position under the action of the balance weight and seals the drain, which plays a role of preventing overflow. Prevent dirty water or odor from overflowing from the sewage pipe and polluting the upper water pipe or indoor air. Overcome the water-sealed floor drain and the S-type and P-type traps. The solid water is easy to breed microorganisms and bacteria to contaminate the pipes. Moreover, if the water is not drained for a long time, the water in the water seal will still contaminate the pipes due to natural evaporation after communicating with the upper pipe. The shortcomings of this product are most suitable to be installed on the frost-proof wide drain for draining water pipes to prevent overflow. It can also be installed on the drain pipes of wash basins, wash basins, bathtubs, etc., to prevent the phenomenon that the water seal inside the water seal is easy to freeze or even freeze and cannot be drained after draining in winter. It can bring about free drainage and automatically realize the environmental protection effect of preventing overflow after drainage. The commonly used specifications of the products are DN15, DN20, DN32, DN40, etc. The materials are brass and PPR.
When the pressure of the piping system disappears, if the outside air is not sucked into the system, it will inevitably create a vacuum in the piping and generate negative pressure, which will damage the piping system and even cause an explosion hazard. The suction valve can quickly inhale a large amount of outside air when the system pressure disappears, so that the pressure in the system is balanced with the atmospheric pressure to ensure that the pipeline system will not be damaged by negative pressure. It is an accessory that can maintain a stable pressure in the pipe without a vent pipe. Set at the highest end of each layer of horizontal branch pipes or the top of stand pipes separated by several layers. Therefore, the suction valve is an indispensable auxiliary component for reducing negative pressure in the piping system, and is widely used in high-rise building heating systems, plant piping, small pumping stations and other pressure pipes and thermal steam pipes that use antifreeze devices. It is often set at the highest point or local highest point of the pipeline system to automatically close and open, so that the pressure difference between the inside and outside of the pipeline is equal, and the consumption of vacuum damages the pipeline or equipment.
When installing the suction valve, install it vertically. When the system pressure disappears, the floating pellet settles under the dual force of the gravity system and automatically opens the air inlet, and the air enters the pipe through the cylinder air inlet. When pressure is generated in the piping system, the float rises under the action of the system pressure to safely block the air inlet of the cylinder. The suction valve is now completely closed.
