A rotary globe valve, including bolts, lock nuts, discs, support sleeves, flanged valve body, compression spring, oil gasket, locking end cap, joint body, end of the flanged valve body on the fuel tank side There is a flaring part at the top, and an external thread is provided on the pump side circumference of the flange valve body; the support sleeve is sleeved on the outer circumference of the bolt, the compression spring is sleeved on the support sleeve, the disc and the oil washer are sleeved on the outer circumference of the bolt and They are respectively located on both sides of the support sleeve, and the compression spring and the oil gasket are installed in the inner cavity of the flange valve; the joint body includes the valve body joint part, the pump joint part and the shoulder, and the valve body joint part is installed in the flange valve inner cavity And against the oil gasket, the pump joint is suitable for connecting the pump oil inlet; the locking end cover has a cylindrical inner hole, and the inner peripheral wall of the inner hole on one side is provided with an internal thread, and the internal thread and the external thread on the pump side The threaded connection, the inner peripheral wall of the inner hole on the other side is formed with a thickened part, and the thickened part and the shoulder abut against each other. The valve can be directly installed on the oil tank, the overall space is small, and the joint forms are diversified.
Description
technical field [0001] The invention belongs to the technical field of hydraulic equipment, and more particularly relates to a rotary stop valve. Background technique [0002] In the hydraulic equipment of mobile machinery, the connection between the hydraulic oil tank and the oil suction port of the pump is generally connected by a butterfly valve, a globe valve or a ball valve. The ball valve is closed to prevent oil from leaking from the tank. [0003] Since the power element connected to the pump is a vibration source, and the fuel tank is fixed on the frame of the mobile machine, vibration reduction is required between the pump and the fuel tank. For example, the pump suction port is required to be connected to a butterfly valve, globe valve or ball valve through a hose, and then connected in the fuel tank. However, the current butterfly valve, globe valve, ball valve and other connection forms are mostly flange or threaded connections, which need to be connected to t...
