Embodiment Construction
[0009] Such as figure 1 As shown, a self-operated unloading valve includes a valve body 8, a valve cover 1, a valve seat 3, and a valve plate 2. The valve body 8 and the valve cover 1 are connected by bolts, and the valve seat 3 is located on the valve cover 1. The conical surface of the plate 2 forms a sealing pair, the valve plate 2 is fixedly connected with a guide rod 6, a guide sleeve 7 is fixed inside the valve body 8, the guide rod 6 passes through the guide sleeve 7, and is between the back of the valve plate 2 and the guide sleeve 7 The spring 5 is equipped with a spring sleeve 4 outside the spring 5. The spring sleeve 4 is fixed on the valve plate 2. There is a pin shaft 9 at the lower part of the guide rod 6. The valve shaft 11 runs through the valve body 8, and a fork 10 is fixed on the valve plate. On the valve shaft 11 of the inner cavity of the body 8, the pin shaft 9 is located in the opening groove of the fork 10, a connecting rod 13 is installed on the valve ...

The invention provides a self-operated discharge valve. The self-operated discharge valve comprises a valve body, a valve deck, a valve seat, and a valve plate; the valve body is connected with the valve deck through a bolt; the valve seat is positioned on the valve deck, and forms a seal pair with the conical surface of the valve plate; the valve plate is fixedly connected with a guide rod; a guide sleeve is fixed in the valve body; the guide rod passes through the guide sleeve; a spring is arranged between the back of the valve plate and the guide sleeve; a spring sleeve is arranged outside the spring; the spring sleeve is fixed on the valve plate; a pin shaft is arranged on the lower part of the guide rod; a valve shaft passes trough the valve body; a shifting fork is fixed on the valve shaft of an inner cavity of the valve body; the pin shaft is arranged in an open slot of the shifting fork; a connection rod is arranged on the valve shaft outside the valve body; a support plate is fixed outside the valve body; and holes into which a lock pin is inserted are processed at the other end of the connection rod and the support plate. The invention has the advantages that the self-operated discharge valve has a simple structure, and is reliable in sealing; the valve is opened and closed by gravity of a material, and is not needed to be driven by any power; and the material discharge frequency is controlled by the lock pin, so false operation is avoided, and a system can run safely.
Description
technical field [0001] The invention relates to a valve device, in particular to a discharge valve for discharge. Background technique [0002] The unloading valves currently used in ash unloading systems in the metallurgical industry generally adopt the form of ball valves or bell valves. Their common feature is that they use electric devices or pneumatic devices to operate the valves. First, the system is complex, costly, and consumes energy. Contents of the invention [0003] In order to overcome the shortcomings of the existing unloading valve control system such as complexity, high cost and energy consumption, the present invention provides a self-operated unloading valve. [0004] The technical solution adopted by the present invention to solve the technical problem is a self-operated unloading valve, which includes a valve body, a valve cover, a valve seat, and a valve plate. The valve body and the valve cover are connected by bolts, and the valve seat is located on...
