Abstract
The utility model relates to a series of fluid valves of different materials which are suitable for fluid equipment. The interior of each valve body (3) is provided with a valve core (5), the interior of each valve core rod is provided with an axial valve port (4) which is communicated with four side ports, the upper end of the valve core (5) is provided with a valve disk (7) which is provided with a sealing gasket (6), the top of the valve disk (7) is provided with an oil passage gap (8), the valve core (5) is provided with strokes in a series of specifications, a spring (9) is arranged between the valve disk (7) and a transition piece (10), the transition piece (10) is provided with a channel (12), and the shoulder and the axilla of the transition piece (10) are provided with sealing O gaskets (11) and (2-1) respectively. In the normal operation, a bottom cap (1) is screwed on the lower side of the valve body (3) (figure 1). When the oiling of the oil discharging is needed, the bottom cap (1) is screwed down, and the oil nozzle (13) is screwed on. (When the oiling is carried out, the gasket (14) can be removed.) (figure 2).
Description
The utility model relates to a kind of fluid valve of power equipment
Mostly fluid valve on power equipment is the single structure special purpose at present, as stop valve, one-way valve and fuel outlet valve etc., adopt firmly seals more, mostly be cast copper cast-iron body or steel ball or cone etc. and adopt manually as the valve port spool seals more, if opened and closed often or operating method improper, on valve core, be pressed into groove mark easily, special copper spare, also valve port distortion sometimes, this is to cause main cause of seepage.
The purpose of this utility model provides a kind of fluid valve of power equipment special use, makes its section, puts, oiling and draw oil sample and be the structure of one, adopts soft seal for to close from press seal.
The technological scheme that the utility model is implemented is:
It comprises a valve body, a spool is arranged in the valve body, and the spool upper end is provided with the valve disc of a seal rubber pad, and the valve disc bar has the duct and uses as the oil suction of drawing oil sample as path, the bar lower end taper mouth of fluid, in order to prevent valve core rod leakage of oil when moving, on valve body, be provided with sealing O circle, one resetting spring arranged, push down by transition piece at the spool top, in valve body lower portion bottom is housed, multi-purpose valve, convenient maintenance and maintenance improve the power equipment safety operational reliability.
Need drain the oil, oiling or when drawing oil sample, back out the bottom oil of screwing on and chew and back down spool and can drain the oil; Taking out the packing ring of oil in the chewing oil of screwing on chews and loads onto oil pipe and get final product oiling; Back out bottom align spool (5) bar mouth promote spool (5) can the oil suction sample; Utilizing spring and hydrodynamic pressure to push down spool realizes damming; Each movable joint position is provided with not easy to leak oil of seal rubber pad or cushion rubber.Describe technical solution in detail below in conjunction with embodiment's accompanying drawing
Fig. 1 is that fluid valve structure sectional view Fig. 2 is for fluid valve is put, the oiling schematic representation
A spool (5) is housed in valve body (3) as can be seen from Figure 1, spool (5) top is a valve disc (7) of adorning seal rubber pad (6), valve disc (7) top is provided with oil duct gap (8), there is axial valve opening (4) to communicate in the bar of spool (5) with 4 side openings, lower end, hole (4) is taper, spring (9) is located between valve disc (7) and the transition (10), duct (12) is arranged in the transition piece (10), shoulder and oxter at transition piece (10) respectively are provided with sealing O circle (11) and (2-1), bottom (1) is twisted solid below valve body (3) when normal operation, after taking out the metal washer (14) in You Zui (13) during as oiling earlier, the oil of screwing on is chewed (13) and is plugged oil pipe and utilize pressure to open spool (5) to carry out oiling, sealing O circle is housed between spool (5) bar and valve body (3), and spool (5) has series specification requirement stroke.
The utility model can be made different size to be applicable to the requirement of different fluid medium and pressure with different materials, and above embodiment is medium with oil, and the utility model also can be used for other medium in principle, comprises liquids and gases.
