There Are Several Types Of Valve ConnectionJun 27, 2018
The main forms of the valve are flanges, threads, card sleeves, clamps, internal self tightening, welding, clips and so on. They are suitable for different occasions, and the following are introduced in detail.
1, flange connection is the most frequently used connection form in valves. According to the shape of the joint surface, it can be divided into the following types: 1) smooth type: used for valves with low pressure. Processing is more convenient 2) concave and convex type: high working pressure, can use the hard washer 3) tenon and grooves: with large plastic deformation washer, in corrosive medium is widely used, better sealing effect.
How To Repair The Valve Cover Of The ValveJun 27, 2018
Valve in the use of the process, even in the shelf life even extend a few years will not be a problem, but sometimes the valve bonnet will also encounter external damage. When the damage occurred, Shanghai Huagang valve factory suggested to ensure the normal use of valves and re purchase new products. In general, the valve with low price is repurchased directly, and the relative high price valve, if it is not willing to purchase new products, can be repaired when the valve is not used.Learn More
What Kinds Of Common Globe Valves Are ThereJun 27, 2018
1) angle cut-off valve: in the angle stop valve, the fluid needs to be changed only once so that the pressure passing through this valve is smaller than that of the conventional cut-off valve.
2) DC shut-off valve: in the DC or Y type cut-off valve, the flow channel of the valve body is a slash line with the main channel, so that the damage degree of the activity is smaller than the conventional cut-off valve, and the pressure loss through the valve is also smaller.
Ball Valve Maintenance And Maintenance DetailsJun 27, 2018
Ball valve is a kind of universal valve widely used in the valve. It has a large amount of usage and consumes quickly. Therefore, reasonable maintenance is very necessary. Reasonable maintenance can not only improve work efficiency, but also reduce repair time and save replacement cost. ,Learn More
Careful Attention When Using A Butterfly ValveJun 27, 2018
The pinch butterfly valve is especially suitable for the place where the space is narrow or the distance between the pipes is short. When the butterfly valve is completely opened, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body, so it can be reduced very small by the pressure produced by the valve, so it has a better flow control characteristic. Let us explain what are the precautions before installing butterfly valves.Learn More
Characteristics Of Knife Gate ValveJun 27, 2018
1) the knife type gate valve adopts the clamp structure, which has compact structure, small volume, light weight, small space, easy to install, open the power saving of the shutoff valve, and reduce the labor strength of the maintenance workers.Learn More
Use Of Knife Type Gate Valve And PrecautionsJun 27, 2018
1) the clamp type knife type gate valve is mainly used in the heavy medium and coal mud water pipe, in the pipeline mainly do cut-off use, can not be used as the regulating flow, the gate should be fully open or completely closed, so as to avoid seal or gate erosion, accelerate wear and greatly reduce the service life.Learn More
How To Choose A High Quality Butterfly ValveJun 27, 2018
Butterfly valve introduction:
1, the butterfly valve has the characteristics of simple structure, small size, light weight, material consumption, small installation size, quick switch, 90 degree reciprocating and rotary, small driving torque, etc., for cutting, connecting and adjusting the medium in the pipeline. It has good fluid control characteristics and close sealing ability.
What Are The Related Notices For The Check Valve?Jun 27, 2018
Check valves are used as an automatic valve in the pipeline to prevent the reverse flow or leakage of the medium in the pipeline. There are various types of check valves on the market. There are also a variety of design forms, such as connecting forging steel check valves, sealing forged steel check valves and so on. Whatever type of check valve, it can be well protected. The one-way flow of the stop medium or the action of preventing backflow. So what should we pay attention to during the process of installing and installing check valves?Learn More
What Do You Need To Pay Attention To The Connection Of The Flange?Jun 27, 2018
(1) flange connection should adhere to the same axis, and the center deviation of its bolt hole generally does not exceed 5% of the hole diameter. The connecting bolts of the flange should be the same specification, the equipment direction should be common, and the bolts should be symmetrical and uniform when tightening bolts.Learn More
