Post office lost fire hydrant hose coupling, baicheng fire control shall be ordered to make correction

In order to further strengthen the fire safety work in crowded places, vigorously regulation of various types of fire hazards, reduce fire hazards, keep steady fire situation.On April 23, baicheng city of jilin province public security fire control team tongyu brigade of jurisdiction the postal system for fire control safety inspection.
In the process of inspection, the fire prevention supervision personnel to the inspection unit of evacuation exit signs, directional signs, emergency lighting setting is in accordance with the provisions, the evacuation passageway and safety exit was clear, fire hydrant, fire extinguishers, fire doors, fire control facilities is normal working status, fire safety management system is sound and emergency disposal plan is formulated, and organize regular fire drill, and so on and so forth has carried on the detailed screening.
Inspection found that the unit on a wall inside the fire hydrant fire hose is missing, is used to pump water, and will fire hose coupling to unload.Fire prevention supervision personnel shall be ordered to correct immediately, and the units of the legal persons, the fire managers criticism education, also requires the unit leaders to strengthen fire safety work seriously, to improve the level of employee "four abilities".
After the inspection, fire prevention supervisors to go further by calling for a unit manager should be self-checking introspection, firmly to prevent fire accidents.Through this inspection, not only the timely and effective to curb some of the fire hazard, as well as jurisdiction fire security work has laid a solid foundation, further purify the area of fire safety environment.

Metal hose coupling

Metal hose coupling is a kind of high quality flexible pipeline in modern industrial pipeline. It is mainly composed of corrugated pipe, net sleeve and joint.Its inner tube is a spiral or annular thin-walled stainless steel corrugated pipe, corrugated pipe outer net, is made with stainless steel wire or steel tape according to certain parameters.At the ends of the hose connection or flange is pipe joints or flanges matching with the customer pipeline. Hose corrugated pipe is made of very thin-walled seamless or the welded stainless steel pipe through high precision plastic processing. Due to the elastic properties of corrugated pipe contours determines the hose has good flexibility and fatigue resistance, making it easy to absorb all kinds of motion and deformation of cyclic load, especially in the pipeline system has ability to compensate for large displacement ability. Visual medium (visual) , process automation.

What is the hose coupling

The hose coupling is a connector on the end of a hose to connect (or couple) it with another hose or with a tap or a hose appliance, such as an irrigation sprinkler. It is usually made of steel, brass, stainless steel, aluminium or plastic.

The characteristics of Camlock coupling

Camlocks also called cam and groove coupling, a kind of Hose coupling used to rapidly connect and disconnect fitting on piping or hose, they come in a variety of materials to be used with different liquids and a variety of sizes to accommodate hose or piping diameter.We K&G MACHINERY summarizes the characteristics of Camlock coupling are listed below.

Camlock coupling has the following characteristics:

(1) The installation saves time and effort: When Camlock coupling Series connector connect supporting facilities has the corresponding size connector matching with it, so simple installation operation, saving time and manpower.

(2) Model diversification: Camlock coupling model includes eight kinds for customers to choose; At the same time  supporting the needs of different customers different thread standard..

(3) Environmental protection: Camlock coupling can be used through the threaded connection ,supporting the use of the valve, when the quick connector broken and connection, closed by the valve regulating the oil will not spill leak and protect the environment.

(4) The device uniquely designed for easy transport: large equipment or need portable hydraulic tools, the use of quick connectors spin transport, destination and then assembled using.

(5)The economy: the above a variety of advantages over both for customers to create economic value.

What are Hose Couplings?

Hose couplings are a connection fitting that is found on the end of a hose.  The device makes it possible to connect the hose with another hose, or with some type of machinery or appliance.  Usually constructed with brass or steel, a hose coupling may be designed in several basic patterns.  Choosing the right hose coupling normally depends on the types of hoses involved as well as their intended use.

In many cases, hose couplings are designed to create a seal that is both airtight and watertight.  This makes the devices especially helpful when the hoses are used to transport liquids or gases of some type.  Some designs use either male or female thread designs, while others are classified as sexless hose couplings.

One of the more common types of hose couplings is known as the Storz coupling.  This design requires very little effort to connect, as it requires no more than lining up the coupling with the device and locks in place with a simple quarter turn.  A Storz hose coupler is often the choice of many municipal fire departments, as they make it possible to quickly attach a fire hose to a hydrant when attempting to bring a fire under control.

A variation on the Storz coupling is known as the Nakajima.  This style of coupling also connects with a simple quarter turn.  What is different is that hose couplers of this type also come with a locking device on the exterior.  The lock can be especially helpful when connecting the hose to machinery that will move liquid or other agents through the hose at high pressures.

In Spain, the Barcelona hose coupling is common for use with fire trucks as well as connecting with local water systems when necessary.  This design also makes use of a combination of male and female threads and must be screwed into place.

French fire fighters tend to utilize a hose coupling configuration known as the Guillemen Symmetrical Clutch.  As with the Storz and Nakajima designs, this type of coupling connected with a simple quarter turn.  Two protuberances are found on the exterior of the clutch, which allows the device to adjust to the hook of each hose as the ring turns during use.

The National hose coupling, also known as an NST, is also commonly used with fire hoses.Requiring more than a simple turn and lock process, the NST requires several full turns to complete the connection.  The straightforward male and female thread combination makes it possible to quickly screw the coupling into position.  A gasket helps to seal the connection. This type of coupling works well as a nozzle holder as well as several other hose accessories.
