The equipment and protection of hard sealed rods should pay attention to the following matters: it is prohibited to use handwheels, handles, and transmission mechanisms for lifting, and collision is prohibited. The double gate valve should be straight (i.e. the hard sealing rod is in the straight position and the handwheel is at the top). Before using a bypass valve to open the gate valve, the bypass valve should be opened to balance the pressure difference between the inlet and outlet and reduce the opening force.

The gate valve with transmission mechanism shall be equipped according to the provisions of the product operation manual. If hard sealed closing rods are frequently used, they should be smoothed at least once a month. Structural features: Ordinary gate valves that have been used in the market for a long time have been leaking or rusted. Yongjia County Baiou Valve Accessories Co., Ltd. uses high-tech rubber and valve manufacturing technology to produce elastic seat sealed gate valves, in order to overcome the shortcomings of poor sealing and rust of ordinary gate valves.

The elastic seat sealed gate valve utilizes the compensation effect of slight elastic deformation of the elastic gate to achieve excellent sealing effect. Hard sealed rods have obvious advantages, such as lamp switches, reliable sealing, good elastic memory, and service life. It can be widely used for regulating and intercepting pipelines in tap water, sewage, construction, petroleum, chemical, food, medicine, textiles, electricity, ships, metallurgy, power systems, and other fields.

The groove type hard sealed closed rod usually has single gate, double gate, wedge shaped, parallel and other structural designs. Among them, wedge-shaped double rams (Z42, Z62 series) and wedge-shaped elastic rams (Z40, Z60 series) are widely used. When the current one is closed, the gate automatically matches with the valve seats on both sides to automatically compensate for the machining position error of the wedge angle; The latter relies on the elastic groove in the middle of the gate and the axial thrust of the valve stem to compensate for the machining position error of the wedge angle, both of which can achieve better sealing effect.
