1.Float valves are usually installed in the standard holes of the tool joints, it is used to control the liquid flow at the bottom of the drill pipe. In the time of exchanging drill Pipe, float valve also can prevent the cutting come back from the bit nozzles.

2.Features:

Float valve fittings is a kind of BOP joint drill, it is installed float valve in the bore. Connection's threads can be designed by user, we’ll assemble float valve according to the size of the thread as per API standard.

Q: Can I use other types of bearings instead? What's the model instead of the bearing? Thank you: Hello, please check the model of this bearing in detailThere is no PN307 modelWith RN307, cylindrical roller bearings, bore 35Then consult me

Q: 1.6 of the two case K2 rear wheel bearings are the same as the other K2?: I would like to ask whether you have seen bearing down bearing types and brands,

Q: FAG bidirectional thrust angular contact bearing 234416M.SP can be replaced by other manufacturers?: Japan NSK Code: 80TAC20XLJapan NTN code name: 562016SKF code name: 234416TN9/SPDomestic HRB Code: new code name: 234416. Old code name: 2268116

Q: Machine specific, please describe the specific points: Outer spherical bearings: spherical roller bearings with wide outer rings and outer rings with locking elements. Mainly for simple housingsLinear motion bearing: two roller, in the direction of rolling has relatively linear motion of rolling bearingsBall bearing: the rolling body is the rolling bearing of the ballDeep groove ball bearings: ball bearing continuous groove of each ring has a cross section of the ball about three weeks of the raceway, suitable for precision instruments, low noise motor, automobile, motorcycle and general machinery, is the most widely used type of bearings in machinery industry. Simple structure, use and maintenance convenient. Mainly used to bear radial load, also can withstand certain axial load, when the bearing radial clearance increased, with the performance of angular contact ball bearings, can withstand higher axial loads. The bearing friction coefficient is small, high limit speed, different size and forms. Solid and durable, strong versatility and low noise operation, easy to install and can be run at a high speed. The design of deep groove ball bearing and sealing, without lubrication and no maintenance. Separate with ball gap and double ball bearings, suitable for heavy load. Condition.Thrust ball bearings: rolling bodies are thrust ball bearingsRoller bearings: rolling bodies are roller bearingsCylindrical roller bearings: rolling bodies are cylindrical roller radial roller bearings, is a separate type bearings, installation and disassembly is very convenient. Cylindrical roller bearings are divided into single, double and four column

Q: In bearings, why are the flanges connecting the upper and lower cases higher than those of the other bearings?: If it is understood as the reducer, the upper and lower box connecting the flange (bearing box outside the prominent part), the reason is to prevent the bearings in operation, gear and box friction, damage box, reduce gear life.

Q: In addition there is no other original bearing high speed bearing deposit in 50 seconds or more for the name?: If love childrenhealth don't buy flat shoes, FSK shoes, skate, play special brake, running and jumping. Well, if you like something more exciting, limit your shoes.

Q: when the ball bearings bear the equivalent dynamic load doubled, how will the bearing life changes? When other conditions are constant, how will the life of the bearing change when the speed of the ball bearing is doubled?: The dynamic load increase or decrease is not the main reason for the bearing's life, so far there is no specific formula can be called out and life ratio, the main reason is that determines the life, life = rated speed * * unit unit time temperature / time * temperature value is not completely accurate, anyway and environment. The temperature, the length of time, there is relationship between static and dynamic load!

Q: What model is used more? What are the prospects for development? Does the price have an advantage?: Relatively speaking, the number of general, small and medium is relatively largeThe prospect is also OK, the domestic price has the absolute superiorityYou can consider to do the foreign trade in the bearing industry

Q: Must the axle neck fit with the bearings? Is there anything else you can use? Or nothing?: The rotating part of the supporting shaft must have a bearing, either a rolling bearing or a sliding bearing.

Q: I want to use laser displacement sensor to measure the displacement of the slider. I hope the master will recommend a sensor.: A ZLDS100 laser displacement sensor is a digital integrated structure with no controller and direct digital output.
