Embodiment Construction

[0019] The theoretical basis of the present invention is that the oil discharge valve seat will be connected with the tank body on the one hand, and will be connected with the lower discharge valve on the other hand. The part connected with the tank body requires high rigidity, but the part connected with the unloading valve needs to increase the size of the oil discharge port as much as possible to increase the flow rate, so the cross section of the oil discharge valve seat is thin at the bottom and thick at the top.

[0020] see figure 1 , figure 2 , image 3 as well as Figure 4 , the present invention provides an oil filling and draining valve seat, the oil filling and draining valve seat includes a bottom 1 of the oil filling and draining valve seat and an oil filling and draining valve seat root 2 extending upward from the edge of the bottom 1 of the oil filling and draining valve seat, for Ensure that the oil discharge port is as large as possible, thereby eliminati...

Abstract

An oil charging and discharging valve seat is applied to a bottom unloading oil discharging device or a top loading bottom unloading oil discharging device, and is connected to an oil charging and discharging valve of a tank body. The oil charging and discharging valve seat comprises an oil charging and discharging valve seat bottom portion (1) and an oil charging and discharging valve seat root portion (2) that extends from the edge of the oil charging and discharging valve seat bottom portion to an upper portion. The thickness of the oil charging and discharging valve seat bottom portion is smaller than the thickness of the oil charging and discharging valve seat root portion. The oil charging and discharging valve seat is high in working efficiency and good in tightness, and is easy to form.

Description

technical field [0001] The invention belongs to the field of machinery, and relates to a valve seat, in particular to an oil filling and discharging valve connected with a tank filling and discharging valve, which is applied to a bottom unloading oil discharge device used on a railway tank car or a bottom loading and unloading oil discharge device. seat. Background technique [0002] At present, when the railway tank car adopts the oil discharge device or the oil discharge device, the oil filling and discharging valve seat connected with the oil filling and discharging valve at the bottom of the tank body generally adopts steel plate machining or casting. For the oil filling and discharging valve seat, the currently adopted method is to directly open the oil discharge port at the bottom of the tanker, and a filter screen is provided at the opening and the connecting part (oil filling and discharging valve) of the filling and discharging valve, but when using pneumatic contro...
