Abstract
The utility model discloses a right-angled direct pressure relief valve. The right-angled direct pressure relief valve is characterized by comprising a right-angled valve body, wherein a valve bush is arranged in the valve body and is positioned between an inlet end and an outlet end; the upper end of the valve bush is connected with a valve cover; the lower end of the valve bush is connected with the outlet end; a gate hole is formed in the lower part of the valve bush and is communicated with the inlet end; a sliding sleeve gate is arranged in the valve bush and is connected with the valve bush in a sliding way; a spring adjusting cavity is arranged on the valve cover; an adjusting screw is arranged in the spring adjusting cavity and is in threaded connection with a press plate nut in the spring adjusting cavity; a spring is arranged between the press plate nut and the sliding sleeve gate; a valve bush shoulder is arranged at the middle of the valve bush; and an end plate at the upper end of the sliding sleeve gate is outward protruded to form a lug boss matched with the valve bush shoulder. The right-angled direct pressure relief valve disclosed by the utility model has the advantages that the control valve is simple in structure and has fewer in parts; no worn parts except a sealing element exist; the sealing element can be replaced by opening the valve cover and taking out the sliding sleeve gate; and online maintenance can be realized.
Description
Technical field
The utility model relates to the technical field of valve, is specifically related to the direct Decompression valves of a kind of rectangular shape.
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 rectangular shape direct 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: the direct Decompression valves of a kind of rectangular shape comprises a right angle valve body; Valve body side, said right angle is provided with entrance point, and this valve body bottom, right angle is provided with outlet end, and this valve body upper end, right angle is provided with valve gap; Be provided with valve pocket in this right angle valve body, valve pocket is between entrance point and outlet end, and the valve pocket upper end is connected with valve gap; The valve pocket lower end is connected with outlet end, and the valve pocket bottom is provided with the lock hole and is communicated with entrance point, is 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, and this spring is regulated in the chamber and is provided with an adjusting screw rod; Adjusting screw rod is threaded with the panel nut that this spring regulates in chamber is set, and is provided with spring between panel nut and the sliding sleeve lock, and the valve pocket middle part is provided with valve pocket and takes on; Sliding sleeve lock upper end end plate outwards protrudes, and forms the boss that matches with this valve pocket shoulder.Portion is provided with flashboard in the sliding sleeve pocket floor, is provided with the seal arrangement that matches with said flashboard in the valve pocket lower end.Sliding sleeve lock upper end is provided with wear-resisting circle and Sealing, and the wear-resisting circle of sliding sleeve lock 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 the top surface area of sliding sleeve lock inner chamber 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.
