Valves division of sri pumps group has successfully developed, A wide range of butterfly valves, either with manually operated handle or with Automated Rotary actuators having its end connection confirming to SMS, IDF,DIN unions or with plain weld able type ends. These Butterfly valves have a naturally high pressure-recovery factor, which is used to predict the pressure recovery occurring between the vena contract and the outlet of the valve. The valves ability to recover from the pressure drop is influenced by the geometry of the wafer-style body, the maximum flow capacity of the valve, and the service's ability to cavitations or choke. Because of the high pressure recovery, butterfly valves work exceptionally well with low-pressure drop applications. The material construction of the valve is SS304, 304L, 316 & 316L.Its range starts from 1" up to 4" for an allowable pressure ps of 10 bar having various applications in Food processing, Breweries, Pharmaceuticals, Cosmetics, Milk processing and many other industries.

Air Atomizing Spray Nozzle mixes liquid & air to give fine mist like formation. In common situation we can get super fine liquid spraying drops. Adjustable atomized nozzles can adjust liquid capacity and it can meet the requirement of spraying without changing air pressure and hydraulic pressure therefore it has good adaptability. Each spray device is composed of air cap and liquid cap which can offer two spray modes flat fan and round with wide liquid capacity coverage. There are various available sizes of inlet joint for these type of Spray Nozzles. It is flexible with changeable parts. Atomizing Nozzle has good moisture effect. It is the ideal choice for the location where requires moisture control. Application: Moisturization, Mould Lubricating, Spraying Injection, Air Disinfection, Humidification.

The opening and closing part of stainless steel flanged gate valve Z41W is wedge disc, the movement direction of wedge disc is perpendicular to the fluid direction, the gate valve can only be fully open and fully closed, can ‘t be adjusted or throttled. Wedge disc has two sealing surfaces, the two sealing surfaces of most common mode of gate valve form wedge, the wedge angle vary with the valve parameters, Usually the angle is 50 , and it is 2 ° 52 when medium temperature is not high. The wedge disc of wedge gate valve can be made into one piece, which is called the rigid wedge disc; It can also be made into wedge disc which produces small quantities of deformation in order to improve its manufacturability, to make up the deviations of sealing surface angle arising during processing, this wedge is disc called the flexible wedge disc.

Dark-colored inkjet transfer paper is suitable for transferring images onto dark-colored cotton or cotton-mixed fabrics. It is printed with common color inkjet printers using pigment ink or water-based ink.
1.Printing
-Printer setup. Recommend to select Photo Quality Inkjet Paper mode for satisfactory printing results.
-Print the wishful image onto the transfer paper. Then leave it to dry for about 10 minutes.
-Cut out the image, leaving a narrow margin of 5 mm around the pattern edges.

2.Transferring
-Preheat the heat press machine and set the recommended transfer temperature to 170-180.
-Peel off the base paper from the printed coating, and the coating would remain as a film-like material.
-Place the image coating on the textile, printed (image) side facing up.
-Put the isolation paper on the image, the glossy side facing down.
-Transfer for 15-30 seconds, then remove the textile from machine, peel the isolation paper after cooled.

3.Washing
-Its best not to wash the textile in 24 hours after transferring.
-Washing the textile in cold or 30-40 water. Do not wash with strongly alkaline detergents, and no bleach. Avoid rubbing the transferred pattern when hand washing.
-Do not wring. Line dry in shade recommended.
-Dont dry-clean.

Detail of Goods:
The working principle of the cooling fan is realized according to the energy conversion, namely: electric energy electromagnetic energy mechanical energy kinetic energy. The circuit principle is generally divided into various forms. The performance of the fan will be different with different circuits.
Bearing structure
brief introduction
The common bearings of cooling fan are: ball bearing, oil bearing and magnetic bearing.


Ball bearing
Ball bearing changes the friction mode of the bearing and adopts rolling friction. There are some steel balls or steel columns between the two iron rings, supplemented by some grease lubrication. This method more effectively reduces the friction between the bearing surfaces and effectively improves the service life of the fan bearing. Therefore, the heating capacity of the radiator is reduced and the service life is prolonged. The disadvantage is that the process is more complex, resulting in higher cost and higher working noise.


Oil bearing
Sleeve bearing is a sleeve bearing that uses sliding friction and uses lubricating oil as lubricant and drag reducer. It can be said that it is the most common bearing technology in the market. Due to its low cost and simple manufacture, many products, including well-known brands, are still in use. The utility model has the advantages of quiet in initial use, low noise and low price.


magnetic bearing
The motor of magnetic bearing adopts magnetic system (MS) design, which uses magnetic force to suspend the rotor in the air, so that there is no mechanical contact between the rotor and the stator. The principle is that the magnetic induction line is perpendicular to the magnetic levitation line, and the shaft core is parallel to the magnetic levitation line, so the weight of the rotor is fixed on the running track, and the almost unloaded shaft core is used to support in the direction of the anti magnetic levitation line to form the whole rotor suspended on the fixed running track. Compared with the traditional ball bearing and oil bearing, the magnetic bearing has no mechanical contact, and the rotor can run to a very high speed. It has the advantages of low mechanical wear, low energy consumption, low noise, long service life, no lubrication and no oil pollution. It is especially suitable for special environments such as high speed, vacuum and ultra clean. In fact, magnetic levitation is only an auxiliary function, not an independent bearing form. The specific application must cooperate with other bearing forms, such as magnetic levitation + ball bearing, magnetic levitation + oil bearing, magnetic levitation + vaporization bearing and so on.
