Abstract
The utility model discloses a relief valve. The relief valve is characterized in that a valve sleeve is obliquely arranged between an inlet end and an outlet end, the upper end of the valve sleeve is connected with a valve bonnet, the lower end of the valve sleeve is communicated with the outlet end, a gate hole arranged on the lower portion of the valve seat is communicated with the inlet end, a sliding sleeve gate arranged in the valve sleeve is in sliding connection with the valve seat, the valve bonnet is provided with a spring adjusting cavity, an adjusting screw rod is arranged in the spring adjusting cavity and is in threaded connection with a pressing plate nut arranged in the spring adjusting cavity, a spring is arranged between the pressing plate nut and the sliding sleeve gate, and an end plate at the upper end of the sliding sleeve gate projects outwards to form a boss matched with a valve sleeve shoulder arranged in the middle of the valve sleeve. The inlet end and the outlet end are positioned on the same axis, and an included angle of 30-60 degrees is formed between the axis of the valve sleeve and the axis of each of the inlet end and the outlet end of the valve body. The relief valve has the advantages of simple structure, reasonable design, long service life of a sealing seat, fewer components, light weight and easiness to maintain.
Description
Technical field
The utility model relates to the technical field of valve, is specifically related to a kind of Decompression valves.
Background technique
At present, most of water control Decompression valvess rely on pilot valves to come the switch of control valve, so the speed of valve switch depends on the sensitivity of the bore and the pilot valve of pilot valve, meanwhile cause complex structure, and cost increases, especially small-bore valve.Also having their sealing is the design of resisting valve seat with valve plate stubbornly, and pressure is big more to be pushed up deeply more, and the sealing of extruding type damages easily, causes leakage.To be designed to valve seat identical with valve aperture so general direct Decompression valves is in order to reach peak rate of flow because directly Decompression valves is to lean on the power and the hydraulic pressure of spring to contend with, so valve aperture big spring is big more more.
The model utility content
The purpose of the utility model is to provide a kind of Decompression valves, reaches simple in structure, and reasonable in design, the sealing seat life-span is grown, component are in light weight less, maintenance is easy to purpose.
In order to realize this purpose, the technological scheme of the utility model is following: a kind of Decompression valves, comprise a valve body, and the valve body upper end is provided with valve gap; Valve body one side is provided with entrance point, and opposite side is provided with outlet end, it is characterized in that tilting to be provided with a valve pocket between entrance point and the outlet end; The valve pocket upper end is connected with valve gap, and the valve pocket lower end is communicated with outlet end, and the valve pocket bottom is provided with the lock hole and is communicated with entrance point; Be provided with the sliding sleeve lock in the valve pocket, be slidingly connected between sliding sleeve lock and the valve pocket, valve gap is provided with spring and regulates the chamber; This spring is regulated in chamber and is provided with an adjusting screw rod, and adjusting screw rod is threaded with panel nut in this spring adjusting chamber is set, is provided with spring between panel nut and the sliding sleeve lock; The valve pocket middle part is provided with the valve pocket shoulder, and sliding sleeve lock upper end end plate outwards protrudes, and forms the boss that matches with this valve pocket shoulder.Said entrance point and outlet end are positioned on the same axis, and the axis of valve pocket becomes 30～60 degree angles with the entrance end axis of valve body.Sliding sleeve lock outer wall upper end is provided with wear-resisting circle and Sealing, and the wear-resisting circle of sliding sleeve lock outer wall upper end and Sealing and valve pocket upper inside wall sealed sliding are dynamically connected.The valve pocket lower end is equipped with sealing seat and is connected with the outlet end inner wall sealing.The adjusting screw rod upper end is rotationally connected and runs through with spring adjusting chamber and stretches out, and regulates the chamber and is provided with rotation prevention structure, and spring one end places on the panel nut, and the other end places sliding sleeve pocket floor portion.
Liquid flows into from entrance point during use, gets into the valve pocket inner chamber, and when the power that acts on sliding sleeve lock upper head plate boss place during greater than the preset power of spring, valve opening, pipeline pressure obtain discharging; Otherwise when inlet pressure did not reach the power of backing down spring, valve was then closed.The size of the difference decision spring force of sliding sleeve lock upper head plate area and base area, this difference in areas is more little, and spring can be used more for a short time, therefore can reduce the valve big more restriction of big spring more.When inlet pressure surpasses the spring value of setting, valve opening, after the sliding sleeve lock was opened, sliding sleeve pocket floor portion also was under pressure, and further opens the sliding sleeve lock, and flow sharply strengthens, and the pressure in the pipeline is discharged quickly, has significantly reduced the pressure release time.Since the sliding sleeve lock when closing its upper end boss run into the valve pocket shoulder and can stop, so can not be extruded into sealing seat firmly, increased the life-span of sealing seat.The advantage of the utility model is the simple in structure of this Decompression valves, and part is few, except Sealing, does not have quick-wear part, only needs when changing Sealing valve gap is opened, and taking out the sliding sleeve lock is replaceable Sealing, but and on-line maintenance.
