Gate is one of the most common open/close, use of ram (namely the open-close part, in the gate opening and closing a called ram or gate, gate called ram block) to connect (full open) or truncation (seated) line in the medium.It does not allow for river closure, use should be avoided in the open gate trace, because of the erosion of high-speed flow of medium will accelerate the damage of the sealing surface.Double DE gate at the channel center line perpendicular to the gate of the one-sided as lifting movement, like gate cutting medium pipeline, so as the gate valve.

Q:Is the axial force and torque of the wedge gate valve the same?: The sealing performance is good, the gate valve is not easy to be jammed when heated, and is suitable for the parts with frequent switches. B is suitable for steam, high temperature oil and gas medium. C is not suitable for easy coking medium.

Q:What does gate z41t-10 150 mean?: According to JB/T308-2004 "valve type programming method"Z gate valve4 flange connection1 Ming wedge single gateT sealing cover material is copper alloy10 nominal pressure PN10PN16 below no marked valve body code, body material is gray cast iron150 nominal size DN150

Q:What are the standards for the execution of cast iron dark pole gate valves?: Four, summary:1, cast iron gate valve is mainly used as a connection and cut off the role of medium. The opening and closing parts of the valve are ram, and the direction of movement of the gate is perpendicular to the direction of flow of the medium. Cast iron gate valve with ductile iron as the main material, the weight is very light, only about 20%~30% of the traditional gate valve;2, cast iron hidden rod gate valve belongs to the class of products, but also the successor to the traditional gate valve, the use of gate generated by the deformation of the compensation role, so that the valve to achieve good sealing effect. Cast iron dark rod valve with open and close the advantages of convenient, reliable sealing, good elastic memory, long service life, can be widely used in metallurgy, electricity, sewage, medicine, construction, food, textile, tap water, energy and other pipeline regulation and closure devices as.

Q:What is the gate valve for the DN65 hydrant?: Fire hydrant with 65 butterfly valve, ah, how do you use the gate valve?

Q:What gate valve is the J41H-150LBDN100 gate valve?: This is a stop valve, not a gate valve.Gate valve means Z41H-150LB-DN100Wenzhou shintex Valve Manufacturing Co. Ltd.0577Eight thousand six hundred and ninety-oneSeven thousand five hundred and sixteenCall

Q:Which is more expensive, bronze gate valve or brass gate valve?: But the obvious weakness of brass is its poor strength, relatively large volume, and its lack of corrosion resistance.

Q:Does the relief valve have a gate valve?: With the ball valve, needle valve, with the valve did not see, but there should be some.

Q:What are the differences between the gate valve and the cut-off valve?: 3, the valve is used in the system is relatively large, to close the gate off system; and the valve is used in the system is relatively small, and to adjust the flow quantity of the system, can not be closed gate and globe valves of different specifications for a variety of occasions, such as the valve rod the dark bar valve, gate valve, wedge gate valve, single valve, multi valve valve body structure is different, large volume. Generally large and nominal caliber DN50 mostly with gate valve, especially industrial high temperature, high pressure and other occasions.4, the cut-off valve is able to stop and adjust the flow, small footprint, small size, generally less than the nominal diameter, DN50 occasions use it. Two can be closed, in the flow of linear requirements are not high, you can adjust the flow. Just because of its structural characteristics of the valve to make its flow resistance, so there is a demand for throttling with a little more than the gate valve. In addition, the cut-off valve, whether it is a formal or reverse installed, in the opening and closing process, there is always a very difficult, and therefore can not do a great deal, or it is not easy to open and close. In addition, the sealing valve has the characteristics of one-way sealing effect, so that the utility model can prevent the working substance from flowing upstream

Q:Gate valve z45h-10dn250 length of the body?: Z45h-10dn250 body length L=330mm, this valve is hidden bar, elastic seat, sealing gate valve, gate lining, lining fluorine, belong to soft seal

Q:Why can't the pressure measuring point be set at the two ends of the gate valve when measuring the resistance loss of the gate valve?: Because of the unsteady flow of fluid near the inlet and outlet of the valve, the measured data cannot be obtained relatively accurately.
