Good quality manual type block machine & tile making machine is one kind manual block making machine. Hand operated brick making machine can produce hollow block, solid block and simple pavers. The materials are usually concrete, cement, sand and fly ash.It is usually equipped with one small mixer, we call it JQ350 mixer, it is used to stir kinds of materials. Because manual concrete block machine has no hopper, so you need to put materials into mold box by hand.Recently, this kind manual concrete block machine is very popular in Philippines,Nepal and so on. So many customers ask for it. Interlocking manual clay brick making machine, manual interlocking brick making machine is a professional equipment for brick making.It is easy operate and just one person can operate it.This machine with a small body size,so it can conver less land area.Moreover,it can be moved from one to another place easily.All in all,it is better choice for user.
Manual brick machine is high-efficiency. With low consumption of material,every brick can be made in 30-40s,which will ensure a quick production and good quality. Environment-friendly. This brick machine wroks without any fuels just under operation of human.

1, small and lightweight, easy to disassemble and repair, and can be installed in any position.
2, the structure is simple and compact, the operating torque is small, and the 90° rotation is quick to open.
3, the flow characteristics of the linear trend, good regulation performance.
4. The connection between the butterfly plate and the valve stem adopts a non-pin structure to overcome possible internal leakage points.
5. The spherical shape of the outer circle of the butterfly plate improves the sealing performance and prolongs the service life of the valve. The zero leakage is still maintained when the pressure is switched on and off more than 50,000 times.
6, the seal can be replaced, and the seal is reliable to achieve two-way seal.
7. The butterfly plate can spray coating layers according to user requirements, such as nylon or polytetrafluoroethylene.
8, the valve can be designed for flange connection and clip connection.
9, the drive can choose manual, electric or pneumatic.
Electric flange butterfly valve is suitable for temperature ≤ 120 °C or ≤ 150 °C, nominal pressure ≤ 1.6MPa water supply and drainage, sewage, food, heating, gas, ships, hydropower, metallurgy, energy systems and textile and other industries, especially for two-way sealing Easy to corrode the valve body and adjust the flow and shutoff medium.
Valves that use metal seals generally have longer life than elastomer-sealed valves, but they are difficult to completely seal. Metal seals can accommodate higher operating temperatures, while elastomeric seals have temperature-restricted defects.
The electric flanged butterfly valve is usually composed of a rotary electric actuator (0~90° partial rotation) and an electric flanged butterfly valve, which are mechanically connected to each other and are assembled and adjusted.
The butterfly plate of the electric flange butterfly valve is installed in the diameter direction of the pipe. In the cylindrical channel of the electric flange butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0° and 90°. When the rotation is 90°, the valve is fully opened.
The electric flange butterfly valve is simple in structure, small in size and light in weight, and consists of only a few parts. And only need to rotate 90 degrees to open and close quickly, the operation is simple, at the same time the valve has good fluid control characteristics. When the flanged butterfly valve is in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body, so the pressure drop produced by the valve is very small, so it has better flow control characteristics. The butterfly valve has two types of seals: elastic seal and metal seal. Elastic sealing valve, sealing ring can be mounted on the valve body or attached around the butterfly plate.
Valves that use metal seals generally have longer life than elastomer-sealed valves, but they are difficult to completely seal. Metal seals can accommodate higher operating temperatures, while elastomeric seals have temperature-restricted defects.
If the butterfly valve is required to be used as a flow control, it is mainly the correct choice of the size and type of the valve. The structural principle of the electric flanged butterfly valve is particularly suitable for making large-diameter valves. Shanghai Enguang Valve Co., Ltd. butterfly valve is not only widely used in petroleum, gas, chemical, water treatment and other general industries, but also applied to the cooling water system of thermal power plants.
Commonly used electric flanged butterfly valves have two kinds of clip-on butterfly valves and flange-type butterfly valves. The wafer type butterfly valve is connected with the valve between the two pipe flanges with stud bolts. The flange type butterfly valve is provided with a flange on the valve, and the upper flanges of the valve are connected on the pipe flange with bolts.
In the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body, so the pressure drop generated by the valve is very small, so it has better flow control characteristics. Electric flanged butterfly valve has two types of seals: elastic seal and metal seal. Elastic sealing valve, sealing ring can be mounted on the valve body or attached around the butterfly plate.
Valves that use metal seals generally have longer life than elastomer-sealed valves, but they are difficult to completely seal. Metal seals can accommodate higher operating temperatures, while elastomeric seals have temperature-restricted defects.
The main features of the flanged butterfly valve are:
