The opening and closing part of the gate valve is the gate plate, the direction of motion of the gate plate is perpendicular to the direction of the fluid, the gate valve can only be fully opened and fully closed, and can not be adjusted and throttled. The two sealing faces of the most commonly used mode gate valve form a wedge, and the wedge Angle varies with the valve parameters, usually 5°, and 2°52' when the medium temperature is not high. The gate plate of the wedge valve can be made into a whole, which is called the rigid gate plate; It can also be made to produce a micro deformation of the ram, in order to improve its processability, make up for the sealing surface Angle in the processing of the deviation, this ram is called elastic ram. When the gate valve is closed, the sealing surface can be sealed only by relying on the medium pressure, that is, relying on the medium pressure to press the sealing surface of the gate plate to the seat on the other side to ensure the sealing of the sealing surface, which is self-sealing. Most gate valves are forced to seal, that is, when the valve is closed, it is necessary to rely on external forces to force the gate to the seat to ensure the tightness of the sealing surface. The gate valve's gate plate moves in a straight line with the valve stem, called the lifting lever gate valve, also called the bright lever gate valve. Usually there is a trapezoidal thread on the lifting rod, and through the nut at the top of the valve and the guide groove on the valve body, the rotating motion is changed into a straight motion, that is, the operating torque is changed into the operating thrust. When the valve is opened, when the lift height of the gate is equal to 1:1 times the diameter of the valve, the channel of the fluid is completely unblocked, but this position can not be monitored during operation. In actual use, it is the vertex of the valve stem as a sign, that is, the position of the opening cannot be moved, as its full open position. In order to consider the temperature change, the locking phenomenon is usually opened to the apex position, and then reversed 1/2-1 turns, as the position of the fully opened valve. Therefore, the fully open position of the valve is determined by the position of the ram, that is, the stroke. Some gate valves, the valve stem nut is located on the gate plate, the hand wheel rotation drives the valve stem to rotate, and the gate plate is lifted, this valve is called the rotating rod gate valve, or the dark rod gate valve.

Shandong Tiancheng Valve is a large-scale joint-stock valve manufacturing enterprise in Shandong. It was established in 2001 and covers an area of 200 mu.

In 2004, the company obtained the qualification certificate for import and export enterprises of the People's Republic of China. In 2005, it was awarded the 256th member unit of the Valve Branch of the China General Machinery Industry Association, and became a qualified unit for economic exchanges with the Zhongyuan Petroleum Exploration and Control Bureau and Zhongyuan Oilfield. In 2006, it passed the quality certification of Lloyd's Register of Shipping, and in the same year, it obtained the recommended product certificate of the Ministry of Construction, and became a member unit of the Shengli Oilfield Materials Market. In 2007, the company was rated as a special equipment safety license unit of the Shandong Provincial Quality and Technical Supervision Bureau. In the same year, it was identified by the Weifang Municipal Quality and Technical Supervision Bureau as the Weifang Valve Testing Center, and obtained three patent certificates. In 2008, it was rated as a well-known trademark in Shandong Province, and passed the API certification of the American Petroleum Association. In 2010, it obtained the API certification certificate of the American Petroleum Association.
