Botou valve

The future development trend of Botou valves: With the development of large-scale complete sets of technology abroad, a series of new complete sets of equipment have emerged. The characteristics of the development of new complete sets of equipment related to valves are large-scale, high parameterization, high-performance automation, and complete sets, which are compatible with the control methods of these complete sets of equipment.
In the past 20 years, there has been significant development in the control methods of valves abroad. In addition to general manual, motorized, electric, pneumatic, and hydraulic transmissions, the variety of valves with electro-hydraulic linkage, gas-liquid linkage, and automatic control, as well as hydraulic control valves, is constantly increasing and showing a trend of further development. Common valve bodies include gray cast iron, ductile iron, 304 and 316 stainless steel, as well as copper alloys for oxygen valves. Soft sealed valve seat materials are generally nitrile rubber, polytetrafluoroethylene, fluororubber, and ethylene propylene diene monomer rubber. As for the application, the performance of the seat material should be considered. Therefore, soft sealed gate valves will be the development direction of gate valves and a valve that the water supply industry is willing to adopt. When opening and closing soft sealed gate valves, do not close the sealing performance. Many manufacturers have introduced metal sealed butterfly valves instead of rubber rings
Sealed butterfly valve. Metal flow control valve is a multifunctional valve that uses high-precision pilot control to control flow. Suitable for pipelines that require control of flow and pressure in water distribution pipes, maintaining the predetermined flow rate constant, limiting excessive flow to a predetermined value, and appropriately reducing upstream high pressure. Even if the pressure upstream of the main valve changes, it will not affect the flow downstream of the main valve. Due to the small elasticity of the sealing element, eccentric joints are generally used for butterfly valves.
Slow closing silencing check valve:
The slow closing soundproof check valve has the characteristics of novel structure, reasonable design, good sealing effect, low resistance, high flow rate, and long service life. Can control the speed of opening or closing the main valve, can be adjusted to the best working state on site, can completely eliminate water hammer phenomenon, and achieve the effect of slow closing and noise reduction
Self operated flow control valve:
An automatic constant flow hydraulic balancing valve. The flow rate can be set according to demand, and the flow rate through the valve can be kept constant. Applied in water systems such as centralized heating and central air conditioning, the flow regulation of the pipeline network is completed in one go, turning the network adjustment work into a simple flow distribution. It eliminates the need for flow redistribution during heat source switching, effectively solving the hydraulic imbalance in the pipeline network.
Self operated temperature control valve:
Self operated temperature control valves do not require external energy for automatic temperature regulation. It is suitable for various heat exchange applications using steam, hot water, hot oil, and other media. It is widely used for automatic temperature regulation in heating, air conditioning, and domestic hot water, as well as in special occasions such as chemical, textile, pharmaceutical, and other production processes.
working principle:
The self operated temperature control valve utilizes the principle of liquid thermal expansion and incompressibility to achieve automatic adjustment. The liquid expansion inside the temperature sensor is uniform, and its control function is proportional adjustment. When the temperature of the controlled medium changes, the volume of the temperature sensing liquid inside the sensor expands or contracts. When the temperature of the controlled medium is higher than the set value, the temperature liquid expands, pushing the valve core downwards to close the valve and reduce the flow rate of the heat medium; When the temperature of the controlled medium is lower than the set value, the temperature sensing liquid contracts, and the reset spring pushes the valve core to open, increasing the flow rate of the heat medium.
Usage characteristics:
1. Small size, light weight, and easy installation;
2. Accurate, reliable, and long-lasting;
3. Maintenance free work;
4. Easy to adjust settings;
5. Passive operation (no power supply, normal operation of gas source);
6. No need for expensive debugging costs;
7. The valve body seal adopts a V-shaped high-temperature sealing component to prevent the possibility of the valve stem being too tight or leaking.
Ball type sewage check valve:
The ball check valve body adopts a full channel structure, which has the advantages of high flow rate and low resistance. Using spherical valve discs, suitable for industrial and domestic sewage pipelines with high viscosity and suspended solids.
8. Buried extended rod elastic seat sealing gate valve
Adopting a design scheme that allows maintenance free and extended valve stems, buried in one go, avoiding the expensive cost of valve wells and the huge investment caused by multiple road renovations and valve replacements, beautifying the road environment, being resistant to rolling, and avoiding safety accidents caused by the loss of manhole covers The valve stem can be flexibly customized according to the depth of the valve well. The top of the valve stem is equipped with a valve switch display, and a signal remote transmission device and a valve misoperation locking device can be installed
