Two, Z41X-16Q / RRHX-16Q Shanghai clever rod bolt resilient seated gate valve Product Overview :: Rising stem resilient seated gate valve opening and closing member is a gate, the gate movement direction perpendicular to the direction of the fluid, the valve can only be fully open and fully closed, can not be adjusted and the throttle. Ram has two sealing surfaces, sealing surfaces the most common mode of gate valve forming wedge, wedge angle with the valve parameters vary, usually ,, wedge gate valve can be made into a whole, called the rigid gate board; also be made to produce small quantities of deformation gate in order to improve its process of, to make up the sealing surface angle deviations arising during processing, this gate is called the flexible gate, usually the flange connection. Resilient seated gate valve: soft seal valve Often movements are trapezoidal threaded rod through the valve top nut and the guide groove on the body, the rotary motion into linear motion, which is the operating torque thrust into action. Open the valve, when the gate valve lift height equal to diameter of 1: 1 times, the fluid channel is completely smooth, but at run time, this position can not be monitored. Actual use, is the apex of stem as a sign that the rise to the highest position of the valve stem to see, as its fully open position. Temperature appears to consider locking phenomenon, usually open to the vertex position, and then rewind 1 / 2-1 circle, as the location of a fully open valve. Therefore, the fully open position of the valve, according to damper position (ie a row) drive to determine. Third, the Shanghai clever rod bolt resilient seated gate valve main technical parameters: Brand Name: Shanghai high bolt Model: Z41X-16Q / RRHX-16Q Nominal pressure: 1.0 ~ 2.5MPa Nominal Diameter: 15 ~ 400mm Working temperature: 0 to 120 ℃ Suitable medium: water, oil, gas and other flange standards: GB / T17241.6GB9113 test standards: GB13927API598 Fourth, Shanghai bolt stem resilient seated gate valve clever use: 1 hoist direction ,. soft sealing valve operation, and all should be clockwise closing. 2. In order to facilitate the opening and closing operation of a person, in the plumbing pressure conditions, the maximum torque should open and close 240N-m. 3 ,. As the pipe network in the pneumatic valve, often manually opening and closing, opening and closing rotation should not be too much, is large diameter valves should be transferred within 200-600. 4. If the soft seal valve buried deeper, the operating mechanism and display the distance from the ground ≥1.5m, pole should have added facilities, and fixed rate stability for the people to observe and operate from the ground. That is, the pipe network in the valve opening and closing operation, should not go down operations. 5 ,. soft seal valve opening and closing operation should end mortise and tenon, and the size standard, and for the ground so that people can be directly manipulated from the ground. With a wheel valve does not apply to underground pipe network. General requirements for resilient seated gate valve: 1 ,. resilient seated gate valve manufacturing standards, should explain the basis of the national standard code, if the file should be attached to business enterprise standards, procurement contract. This type valve in the pipe should generally be installed horizontally. 2 ,. resilient seated gate valve models should be specified in accordance with the national standard code requirements. If the enterprise standards, should be specified instructions model. 3 ,. resilient seated gate valve size and type, comply with the piping design documents. 4 ,. resilient seated gate valve job pressure ≥ pipeline working pressure, without affecting the price of the premise, the valve can withstand working pressure should be greater than the actual working pressure pipeline; soft sealing valve closed on either side of the situation should be under able to withstand 1.1 times the value of the working pressure valve without leakage; valve open position, the valve should be able to withstand twice the working pressure valve requirements.
