Classification：Soft sealed floodgate valve
Trade names：
|
| |
| The elastic seat of special-purpose bright pole of fire control seals the floodgate valve |
| Type of the products: GFZ45X |
|
|
The products quote the standard:
Nominal pressure: 1.0- 2.5MPa Working temperature: 0- 80 degrees Centigrade of flange standard: GB/T 17241.6 GB9113
Stimulate the menstrual flow nominally: 50- Suitable medium of 400mm: Water , oil , air ,etc. Experimental standard: GB13927 AP1598 |
Use of the products:
Fire control special-purpose bright pole elastic flat seal floodgate valve get rid of elastic flat seal advantage , floodgate of valve, and can animation valve open degree relatively, in order to be able to in distant place differentiate the turning on degree of the valve relatively, take the corresponding measure in time. It is reliable to open and close rapidly , so often apply to the fire-fighting system . |
Product structure characteristic:
Wrap up the glue valve core wholly
Nodular cast iron skeleton adopt high-performance rubber and sulphurate technology make and cover wholly newly, it is close and firm to laminate, geometry is accurate in size, the sealed elasticity is good, isolate the core metal of the valve from fluid completely, corrosion-resistant.
An organic whole type copper nut
The copper nut of the core of the valve and skeleton of black iron of ball, the adoption special warfare is joined for an organic whole closely, long-term operation and rivers that guarantee is it it downs to be can loose to take off too to strike, prevent leading to the fact the control of the valve to lose efficiency from.
Flat type valve seat
Our company elastic flat seal floodgate valve bottom adopt the whole basin frank general formula design, been equating with all the time the pipeline, it is difficult to pile up incidentals , guarantee that it is reliable to seal, make the fluid unblocked.
Since the sealed valve is covered
Valve overlay with valve body adopting sealed structural design since, in pressure of using of letting in the range, the higher the fluid pressure is, seal the more closely.
Have and seal specially
Between valve stem and valve having sealed structure among overlaying, adopt three o to seal and enclose designing, compared with sealed structure of packing of the traditional floodgate valve, each is sealed closely, grit obstruction to reduce by a wide margin . In any to hold degree , has the pressure and possess the valve stem to lock the function safely in the valve, guarantee the valve stem will not be gone out by the pressure in the course of operating and maintaining , avoid causing personnel's injury
The structure is light and handy
Compact structure, make most heavy to is it reduce 60mm-300mm to be above than traditional floodgate valve highly to work, save the project space; The noumenonn adopts the nodular cast iron material , the more traditional floodgate valve of weight lightens and invites 20% -30% , It is convenient to install and maintain.
Hygienic requirements of the force of food
The valve scribbles and puts with the nonpoisonous epoxy resin within the body, the internal and external surface of core of the valve is covered with the complete bag of rubber, will not present the rust and water or corrode the phenomenon , can be used in life and drink the water system , medical trade of food directly. |
