Hydraulic couplings for DN series 10

Swivel joints, also known as rotary joints, are used to supply and discharge fluids under pressure or below atmospheric pressure from the fixed piping to the rotating parts of various mechanical devices without leakage. For example, it is necessary to supply steam, hot water, hot oil and other hot water used for heating, or cold water used for cooling, such as saltwater, ammonia, and freon, to a rotating roller or dryer; In addition, compressed air, working oil, etc., are supplied to rotating machines such as clutches and chucks that work through fluids.

Slewing joint manufacturer consultation**: 0519-86180788 Jiangsu Benecke Sealing Technology Co., Ltd. now has more than 50 sets of machining centers, CNC machine tools, dynamic pressure testing machines and other professional equipment. In strict accordance with the IS09001 quality specification to manufacture rotary joints and related products...

The corresponding quick couplings of DN10 are: quick coupling 10 JB ZQ4078-1997 (type A) or quick coupling B10 JB ZQ4078-1997 (type B); A type quick coupling and B type quick coupling their quick change connection end is the same, their difference is that the quick change joint and the pipe fitting connection end, quick change joint 10 and pipe fitting connection end is external thread connection, the thread specification is M27 2-6G (both ends are the same), quick change joint B10 and pipe fitting connection end is internal thread connection, thread specification is M24 both ends are consistent); DN10 quick coupling has the same parameters: nominal pressure:

Nominal flow rate 40l min.

The hydraulic quick coupling is designed for special heavy loads, the female joint material is steel chrome plated, the lock sleeve of the male joint and the female joint are hardened, the pressure resistance and fatigue resistance are good, and the two-stage seal is adopted; Leak-free with safety self-locking.

dn refers to the diameter, or inner diameter.

Intelva is the subsidiary of the Spanish inteva group in China, headquartered in Spain.

Intelva's products are mainly involved in medium and high pressure quick couplings, medium and high pressure ball valves, check valves and other fields.

dn refers to the diameter of the pipe.

Pascal Hydraulics is located in Shijiazhuang, Hebei Province, a young and energetic city, relying on the hydraulic association specializing in the sales of hydraulic pipeline accessories network high-tech enterprises, mainly engaged in hydraulic equipment hydraulic pipeline fittings: pipe fittings, high-pressure hoses, seals, hydraulic pumps, valves, cylinders, hydraulic pipe fittings supporting mechanical and electrical equipment, and at the same time developed a high-pressure hose assembly system and metal hose assembly system, which greatly facilitates the purchase of users. The company has a number of technical talents and senior industry solution experts.

Before unplugging, the pressure is removed, especially the cylinder with a tendency to fall freely, and the pressure can also be relieved before insertion, but pay attention to the operation method.

I don't understand too much that the quick coupling used on the hydraulic oil pipe is a quick connection joint in itself, and you only need to push the ring to easily insert or pull it out, which is fast enough.

First, the method of quick installation:

First of all, remove the cylinder with free fall tendency before unloading, especially the pressure can also be relieved before insertion, but pay attention to the operation method;

Then, after the pressure is relieved, the pressure is further dropped on the oil pipe with pressure at the front end of the quick plug, and the most critical experience is to pull out the pressure before relieving the pressure.

Second, a brief introduction to hydraulic oil pipes:

It refers to the high-pressure hose assembly, which is specifically divided into: rubber type (steel wire braiding, steel wire winding), metal hose, low-pressure PU pipe, etc.

Quick Coupling Installation Instructions (II).

The size of the quick connector is based on the user's usage, mainly depending on the shape and size of the interface on your side, and then match the corresponding connector size, specification and model.

If the size of the quick coupling needs to be limited due to the operating space of the coupling, etc., the size of the coupling may need to be customized according to the actual situation.

Specifications of female quick couplings.

There are three sizes of quick connectors: DIN standard (outer diameter 10mm-150mm A IDF standard (1 2in-6in), ISO standard ( .

The quality and use of the quick assembly joint are: the inside and outside of the quick assembly joint are treated with high-grade polishing equipment to meet the surface precision requirements; It is suitable for dairy, food, beer, beverage, pharmaceutical, cosmetics and other industrial fields. The material of the product is: stainless steel L.

Quickly identify the type of stainless steel quick connector: stainless steel quick connector type: 1, type A:

One end is the arc joint stuck in the female connector, and the other end is the connecting thread with internal threads. 2. Type B: One end is a groove with two male heads for pulling ears, and one end is a thread connection with external threads.

3. Type C: One end is a groove with two male heads of the ear card, and the other end is a slub-shaped hose joint. 4. Type D:

One end is a groove with two tab male connectors, and the other end is a threaded connection with an internal thread. 5. E-type: one end is an arc joint stuck in the female connector, and the other end is a hose joint with a bamboo joint.

6. F type: one end is an arc joint stuck in the female connector, and the other end is a thread with an external thread connection. 7. DC type:

It is a groove with two male puller plugs, which can be snapped into the male arc of the cap plug. 8. DP type: It is an arc plug, also called an inner plug.

9. F-type flange: one section is the arc joint stuck in the female connector, and one end is the flange connected by the flange. 10. Type C with flange:

One end is a groove with two puller male connectors, and the other end is a flange with a flange connection.

Imported hydraulic quick couplings are recommended to use Parker Parker, which is currently one of the best brands on the market.

That's what I'm doing, so you can ask me if you have any questions. Thank you! In Pinglun there are...

There are only a few that are imported, Intelva (Spain).

Parker (Germany).

Eaton (USA).

STAUFF (Germany).

HYDAC (Germany).

HAWE (Germany).

Personally, I recommend Inteva in Spain, and the specific decision is made by the landlord.

Spain IntWis' good.

Look at which series, they have their own strengths. For example, the flat series, Stotch's is the best.

Italian products are a little better.
