The common butterfly valve models are as follows: the type of ventilation butterfly valve is d341h, and the remaining mu file is resistant to d341w; Three eccentric clamp hard seal butterfly valve model:

d73h、d373h、d673h、d973h；Center Flange Butterfly Valve Model: D41X, D341X, D641X, D941X; Models of mid-line pinch butterfly valves: D71X, D371X, D671X, D971X.

The butterfly valve specifications and size table are as follows:

Model: D71X F Caliber: 40 800 Pressure:

Pneumatic ball valve is a ball valve with a pneumatic actuator, the execution speed of the pneumatic actuator is relatively fast, the fastest switching speed is seconds, so it is usually called a pneumatic and clear quick shut-off ball valve. Pneumatic ball valves are usually equipped with a variety of accessories.

For example, solenoid valves, gas terminal source processing triplets, limit switches, positioners, control boxes, etc., in order to achieve local control and long-distance centralized control, the switch of the valve can be controlled in the control room, and there is no need to run to the scene or bring manual control at high altitude and danger, which saves human resources and time and safety to a large extent.

Valve DN15 20 25 32 40 50 63 75 90 110 The size comparison is as follows: the number of inches in front of DN corresponds to one by one.

Component diameter.

The nominal diameter of some parts such as flanges and bearings refers to the nominal diameter of the cylinder and head that matches it. DN2000 flange refers to the flange that matches the DN2000 cylinder (container) or head. DN2000 saddle refers to the saddle support that supports DN2000mm containers.

There are also some parts whose nominal diameters are indicated by the nominal diameters of the tubes that match them.

For example, the pipe flange, DN200 pipe flange refers to the pipe flange connected to the DN200mm pipe. In addition, the nominal diameter of some container parts refers to an important size in the structure, such as the sight hole of the sight glass, the shaft diameter of the stuffing box, etc. DN80 (DG80) sight glass, the diameter of which is 80mm.

DN50 valve corresponding to the diameter of 2 inches, that is, the diameter of 50mm;

A valve is a pipeline attachment used to open and close pipelines, control the flow direction, regulate and control the parameters (temperature, pressure and flow rate) of the conveyed medium. According to its function, it can be divided into shut-off valves, check valves, regulating valves, etc.

Valves are control components in fluid transportation systems, which have the functions of shut-off, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief. Valves for fluid control systems range from the simplest shut-off valves to the most complex self-learning control systems.

Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, slurries, oils, liquid metals and radioactive media. Valves are also divided into cast iron valves, cast steel valves, stainless steel valves, etc.), chrome-molybdenum steel valves, chrome-molybdenum vanadium steel valves, duplex steel valves, plastic valves, non-standard customized valves, etc.

The valve model should usually indicate the type of valve, the driving mode, the connection form, the structural characteristics, the sealing surface material, the valve body material and the nominal pressure and other elements. The standardization of valve models provides convenience for the design, selection and sales of valves. Nowadays, there are more and more types and materials of valves, and the type preparation of valves is becoming more and more complex.

The standard is applicable to gate valves, throttle valves, ball valves, butterfly valves, diaphragm valves, plunger valves, plug valves, check valves, safety valves, pressure reducing valves, traps, etc. for industrial pipelines. It includes the model compilation of the valve and the nomenclature of the valve.

The specific preparation method of the valve model.

For example, the valve model: "Z961Y-100I DN150" This is a complete gate valve model, and the final "DN150" is not included in the preparation, which means that the valve diameter is 150mm, which is easy to understand. Front Section:

Z961Y-100i" is seated according to the sequence diagram above, as follows:

Z" is 1 unit; "9" is 2 units; "6" is a 3-unit; "1" is for 4 units; "Y" is for 5 units; "100" is 6 units; The "i" is for unit 7.

The significance of this valve model is: gate valve, electric drive, welded connection, wedge single gate, cemented carbide seal, 10MPa pressure, chromium-molybdenum steel body material.

Although <> China has a unified standard for the preparation of valve models, it is increasingly unable to meet the needs of the development of the valve industry. Where the standard number of the new valve cannot be used, each manufacturer can prepare the model according to its own needs.
