Elastsed istme tihendi väravaventiilid

1. SissejuhatusElastsed istme tihendi väravaventiilid

Elastsed istme tihendi väravaventiilid are also called lifting stem gate valves, also called rising stem gate valves. Usually there is a trapezoidal thread on the lifting rod, through the nut on the top of the valve and the guide groove on the valve body, the rotary motion is changed into linear motion, that is, the operating torque is changed into operating thrust. The opening and closing part of Elastsed istme tihendi väravaventiilid is a gate. The movement direction of the gate is perpendicular to the direction of the fluid. It can only be fully opened and closed, but cannot be adjusted or throttled. The Elastsed istme tihendi väravaventiilid produced by Milestone Valve Company have stable performance and are used in various fields such as petroleum, chemical industry, and water conservancy.

3.Key points of operation of Elastsed istme tihendi väravaventiilid:

1) The opening and closing direction of Elastsed istme tihendi väravaventiilid should always be closed clockwise.
2. Pneumatic valves in the Elastsed istme tihendi väravaventiilid pipe network are often opened and closed manually, and the number of opening and closing revolutions should not be too much, that is, large-diameter valves should also be within 200-600 revolutions.
3) Elastsed istme tihendi väravaventiilid In order to facilitate the opening and closing operation of one person, the larger opening and closing torque should be 240N-m under the pressure of the pipeline.
4) The opening and closing end of Elastsed istme tihendi väravaventiilid should be a square tenon, with standardized dimensions, and face the ground so that people can directly operate it from the ground. Valves with roulette are not suitable for underground pipe networks.
