Q:What is the wedge type gate valve wedge is what mean: According to the gate can be divided into the form of parallel wedge type. (1) wedge type gate. Wedge type gate the sealing surface of a certain angle with the vertical center line of the gate, the size of angle depends on the medium temperature and diameter size. General medium temperature is higher, and the greater the inclination angle is bigger, in order to prevent the temperature change when the gate is stuck, unable to open. Wedge gate sealing than the parallel well.

Q:What is the difference between the cut-off valve and the gate valve?: Selection of stop valve:There are two ways to install the valve, one is the media flow from the top of the spool, the advantage is that when the packing is not under pressure, the pressure can be replaced before the valve packing, there is a long service life characteristics. Another is the media from the bottom of the spool into, and its shortcomings are driving torque is large, is 1 times above the flow, the stem by the axial force of large, easy to bend the stem. Generally suitable for small caliber manual stop valve, to stop the valve closed, the media acting on the spool of force is not greater than 350kg limit. Electric cut-off valve is generally used to enter the media from the top way.Selection of gate valve and stop valve:Valve than the valve structure is simple, better sealing, manufacturing and maintenance to be convenient; shortcomings are fluid resistance, power, and opening and closing efforts. Gate valve, stop valve are fully open, fully closed valve, suitable for making cut off, it is not suitable for use as regulating valve. The application process should pay attention to the characteristics of the valve when selecting. Small pipes and better sealing performance generally use cut-off valve; in the steam system and large diameter pipeline, due to fluid resistance is small, suitable for use gate valve.

Q:What are the advantages and disadvantages of flat gate valves?: The disadvantage of flat gate valve is that when the medium pressure is low, the sealing force of the metal sealing surface is insufficient, so as to achieve satisfactory sealing. On the contrary, when the medium pressure is high, if the sealing surface is not lubricated by the system media or foreign media, often opening and closing may cause the sealing surface to wear too much. Another disadvantage is that the circular motion of the circular gate in the circular flow, only when it is at the valve closed position of 50%, this valve is more sensitive to flow control. Moreover, the gate will produce severe vibration when it breaks the high-speed and dense medium flow. The valve seat can also be throttled if the seat is made of a V - shaped opening and is tightly oriented to the gate.

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 are the structural differences between parallel and wedge valves?: The double gate is pushed aside so that the sealing surface of the valve gate is tightly sealed with the valve body. These double gate parallel gates are mostly used on low pressure pipelines such as small pipelines. Parallel gate valves are also available with single gates, but are rare.That the sealing surface has a certain angle with the vertical center line, bearing higher medium temperature valve, angle the greater the possibility to reduce the temperature when wedged gate rice.Wedge gate valve single, double all.

Q:Installation and operation instructions of knife gate valve: 1. knife gate valve installation, check the valve cavity and sealing surface and other parts, not allowed to dirt or sand adhesion;2. bolts of connecting parts must be tightened evenly;

Q:What is wire feed gate valve? What do you say in French?: Should refer to the threaded valve. Refers to the valve body with internal thread or external thread, and pipe thread connection. Also called thread valves, threaded valves, valves within the toothFlange gate valve is connected to the flange gate valve, this connection is the most common way.We also introduced a lot of threaded valve, can go to the front pages.The main difference is the threaded valve connectionI only know their English, I'm sorry I can't help youBox thread valveFlange valveThreaded valve, screw connected with the valve, should be said that the former is the most professional.

Q:What is the difference between the copper gate valve and the ordinary material gate valve?!: The material of general gate valve is cast iron, and the copper gate valve should be used in special requirement.

Q:Why is gate valve or butterfly valve used for water pump?: General pressure is small, use the butterfly valve, when the pressure is big, use the gate valve. The two main function of the valve is to adjust the flow and easy to overhaul.Zibo Boshan new Duke water supply equipment

Q:What is the difference between the cut-off valve and gate valve, the general will use the cut-off valve instead of gate valve: Stop valve and gate valveThe working principle is different. The stop valve is an upward stem type, and the handwheel rotates and rises with the stem. Valve is hand wheel rotation, stem upward movement. Flow is not the same, the gate valve requires full open, the cut-off valve is not the same. The gate valve has no inlet and outlet direction requirements, and the cut-off valve has the required inlet and outlet!Gate valve and stop valve are shut-off valve, is the most common two valves.From the exterior, the gate valve is shorter than the cut-off valve, especially the bar valve needs a higher height space. Valve sealing surface has a certain degree of self sealing capacity, its spool depends on the media pressure tight contact with the valve seat sealing surface, to achieve tight leakage. Wedge gate valve spool angle is generally 3~6 degrees, when forced to shut down excessive or temperature changes of the valve core is easy to die. Therefore, high temperature and high pressure wedge gate valve, in the structure have taken certain measures to prevent spool stuck. The valve in the opening and closing valve and valve seat sealing surface contact and mutual friction is always so easy to wear sealing surface, especially in close off the valve, the valve before and after the great pressure, sealing surface wear is more serious.
