Q:What about the water leakage at the valve stem of the sanitary manual stainless steel butterfly valve?
2, the big diameter can be purchased by the corresponding specifications of the sealing ring replacement.
Q:Shandong 30 loader multiple valve stem card what's wrong.
1. cards, the most likely cleanliness problem, accounting for 80% of the probability. Because the sale of multi-channel valve to go through more than two experiments, if it is cylindrical problem, should be found before leaving the factory.
Q:What are the connecting ways of valve plate and valve stem of gate valve?
Valve faults:Between the sealing surface is easy to cause erosion and scratches, maintenance is more difficult. Larger size, open need a certain space, long opening and closing time. Complex structure.
Q:What exactly is the stem nut, please
The stem nut is composed of a nut cap and a nut rod; the nut cap is provided with a dustproof sealing groove; the inner circumferential surface of the nut rod is successively provided with an upper and a lower annular grooves; the outer periphery of the nut rod is provided with a ring-shaped groove.
Q:Stem material
5, bearing steelSelection of GCr15, applicable to the nominal pressure is less than 300MPa, the temperature is less than or equal to 300 degrees of ultra-high pressure valve.Used to make the stem more materials, as well as 4Cr10Si2Mo martensitic heat-resistant steel, 4Cr14Ni14W2Mo austenitic heat-resistant steel.The stem nut and the valve stem match with the screw thread, and directly bear the axial force of the valve stem, and the friction between the plate and the support valve. Therefore, the stem nut in addition to a certain strength, but also requires a small friction coefficient, not rust, and stem does not bite and other performance.
Q:Sea poles, stem what's the difference?
The sea fishing sea rod fishing rod: group configuration is more common on hook group and explosion hook group and the bottom fishing, fishing alarm indicating fish. The use of sea pole, anglers can use a multi pole, also called fixed pole, multi way fishing, to increase the probability of fish.The stem is an important part of the valve, used for transmission, on the implementation of the actuator or handle, the following directly drives the spool to move or rotate, in order to achieve the valve switch or regulation role.Material: copper alloy, carbon steel, stainless steel
Q:The stem can be replaced by what poles?
88 Falaibo wind, 1.8 good, with 120 wheels online, to find their own fix.
Q:What do you pay attention to in winter?
Seven, the bait of choiceWinter fishing crucian carp bait hanging on the general selection of worms and red worms, and red is preferred. A hook 3------4 red worms, head out from the red worm. But to maintain the freshness of activity and, if left red two skins, then become "chicken ribs" fish, bait rate will be greatly reduced.Some fishing friends love package in the lead on vegetarian bait, lure fish to increase. That allowed the caution.The correct method, eight young rod fishFound in fishing, most fishing friends are in the crucian eating hook, vigorously backward pole, and then quickly shake the wheel, do not know how often you have to run a lot of fish?. Raft string hook fishing crucian carp is characterized by rod Ling, thin line, small hook, because carp lips are crisp, plus small hook, if the pole pole, it is easy to pull fish mouth fish. So, find the fish, must firmly will pole up, hard rocking wheel, uniform slow traction, so as to ensure that the rate of the fish.The basic principle is: catch rod, light pole, steady force.
Q:About butterfly valve plate and valve stem connection
The taper pin is easy to remove and can only be installed in the same direction.
Q:What is the dish yellow in the valve?
Disc spring: not used on valve stem and nut. Usually, disc springs are used on hard sealing ball valves.
