What valves, what units you are.

I am the hometown of valves, I also have friends to do valve company procurement, I think you should first understand the structure of the valve, if you don't even understand this minimum, then you come out to buy things people ask you how much pressure, how many caliber, hard seal soft seal, how do you answer then? Second, first ask the best of the accessories, who doesn't want to reduce the cost of the current boss? To be a good buyer, you should let the company save more money on the basis of controlling the quality of accessories.

General procurement is the procurement of raw materials and accessories, electrical accessories, etc., should pay attention to the development of the first business, certification, elimination and activation. Negotiation techniques should originate from the acquisition of information, that is, to analyze all the information of the ** business you purchase the material, so that you can have a target on the negotiation table, simply put, you buy clothes, you know how much the best of the clothes, you say that your negotiation will be much easier. There is also the management of daily employees, which is to do what is responsible for what is wrong, you can immediately find the person in charge, and if there is a problem in the province, you will be punished together for procurement.

See what valves your company produces, plastic steel?

Valve body material, sealing material to grasp the characteristics of each material, appearance color or something This needs to be more contact to understand more Some written will be different from the actual and the old man to learn more.

It's not going to be too difficult for you to procure.

The average technician will tell you that if it doesn't work, you can ask the technician for help.

I'm in the valve industry. First of all, you need to know what kind of valve you are going to touch the main one? What is the purpose of the valve?

Air valve or water valve? What is the diameter? How much pressure can it withstand?

How much is the inlet thread? What is the outlet thread? And what is the minimum cost of the valve?

The understanding of valve fittings, which one is lower and which one is purchased.

Fire valve is an important accessory for industrial and building pipeline control. The fire valve is composed of three parts: valve body, opening and closing mechanism, and valve cover. The manufacturer needs to hold a fire valve production license and a special valve manufacturing license.

Commonly used fire valves include gate valves, globe valves, throttle valves, instrument valves, plunger valves, ball valves, butterfly valves, check valves, remote control float valves, solenoid valves, pressure reducing valves, filters, wet alarm valves, etc.

Gate valve] Gate valve is a gate valve (gate valve) is an opening and closing part of the gate, the direction of movement of the gate is perpendicular to the direction of the fluid, the gate valve can only be fully opened and closed, the gate is in linear motion with the valve stem, the door parameters are different, usually 5°, and the medium temperature is not high when it is 2°52'. To improve its manufacturability and make up for the deviation of the sealing surface angle in the processing process, this kind of ram is called elastic ram.

Fire gate valve] fire gate valve opening and closing parts are the gate, the direction of movement of the gate is perpendicular to the direction of the fluid, the gate valve can only be fully opened and closed, can not be adjusted and throttled. The ram has two sealing surfaces, and the most commonly used mode gate valve has two sealing surfaces forming a wedge, and the wedge angle varies with the valve parameters, usually 50, and 2°52 when the medium temperature is not high' 。The gate plate of the wedge gate valve can be made into a whole, which is called a rigid gate; It can also be made into a ram that can produce a slight amount of deformation to improve its manufacturability and make up for the deviation of the sealing surface angle in the processing process, which is called the elastic ram.

The types of fire gate valves can be divided into wedge gate valves and parallel gate valves according to the sealing surface configuration, and the wedge gate valve can be divided into: single gate type, double gate type and elastic gate type; Parallel ram type gate valves can be divided into single ram type and double ram type. According to the thread position of the stem, it can be divided into two types: open rod gate valve and dark rod gate valve.

Characteristics of fire gate valves].

1.Light weight: The body is made of high-grade ductile black cast iron, which is about 20% 30% lighter than the traditional gate valve, and is easy to install and maintain.

2.Flat-bottomed gate seat: The traditional gate valve is often accumulated in the groove of the bottom of the valve due to foreign objects such as stones, wood, cement and stools, iron filings, sundries, etc. after the pipe is washed with water, which is easy to cause water leakage phenomenon due to the inability to close tightly.

3.Overall rubberization: The ram is made of high-quality rubber for the overall inner and outer rubber, and the first-class rubber vulcanization technology in Europe makes the vulcanized ram able to ensure accurate geometric dimensions, and the rubber and ductile cast ram are firmly connected, not easy to fall off and have good elastic memory.

4.Precision casting valve body: The valve body is made of precision casting, and the precise geometric dimensions make the valve body without any debate and finishing to ensure the tightness of the valve.

The difference between the fire valve (gate valve) and the ordinary gate valve: the fire valve is the signal valve, which can be used to distinguish the state of the rock bridge between closed and open in the fire control center with the letter elimination answer number, while the ordinary valve does not have this function, and other structures are almost the same. Of course, the leakage of fire valves requires the quality certificate of the manufacturer of the fire valve.
