Abstract
The utility model provides an adjustable mechanical hydraulic pressure safety valve for a shock absorption room. The safety valve is mainly composed of a connector, a steel ball, a spring, an adjusting nut, a set screw, a gasket, a square shoulder connector and an outer cover nut. The safety valve is characterized by adopting the non-standard connector used for being communicated with the shock absorption room, the steel ball and the spring are installed in the connector, and the end portion of the spring is provided with the adjusting nut capable of adjusting the compression amount of the spring. The safety valve has the advantages that in a control loop with the high-pressure requirement, the control precision of an overflow valve is greatly improved, and a unit can operate safely and reliably.
Description
Technical field
The utility model relates to mechanical equipment technical field, refers in particular to a kind of shock absorbing chamber adjustable mechanical formula hydraulic pressure safety valve.
Background technique
In existing adjusting petrol station design peculiar to vessel, relief valve is as the pressure control valve ubiquity of voltage stabilizing, pressure regulation or pressure limiting effect, in order to guarantee degree of regulation, eliminate hydraulic pressure excitation impact, often in relief valve design, be provided with shock absorbing chamber, and the control of shock absorbing chamber pressure is to be generally communicated with restricting orifice size between itself and oil extraction by experimental method adjustment to guarantee.In later stage running, due to system oil pressure fluctuation, cause that shock absorbing chamber pressure is unstable, cause relief valve pressure to adjust precision not high, easily fluctuation.For the pressure control circuit of having relatively high expectations, traditional only cannot guarantee control accuracy with the relief valve of the board-like shock absorbing of throttle orifice chamber, and serious meeting affects the safe operation of unit.
Summary of the invention
The purpose of this utility model is to provide a kind of shock absorbing chamber adjustable mechanical formula hydraulic pressure safety valve, solves the problem that the fluctuation of relief valve shock absorbing chamber pressure causes relief valve control accuracy to reduce.
Adjustable mechanical formula hydraulic pressure safety valve for a kind of shock absorbing chamber, mainly formed by joint, steel ball, spring, adjusting nut, Cock screw, pad, flat shoulder grafting head and outer cover nut, it is characterized in that: this shock absorbing chamber adjustable mechanical formula hydraulic pressure safety valve adopts nonstandard joint for being communicated with shock absorbing chamber, in joint, install and use steel ball and spring, the adjusting nut of capable of regulating amount of spring compression is installed in the end of spring.
Described joint material adopts 35 section bar processing; Adopting and be threaded with shock absorbing chamber, is 1.6 in the surface roughness that matches, and adopts 45 ° of chamferings with steel ball fitting surface, and roughness is 3.2.
The beneficial effects of the utility model are, having relatively high expectations in pressure control circuit, have greatly improved relief valve control accuracy, are conducive to unit safety reliability operation.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is joint sectional view of the present utility model.
In figure: joint 1, steel ball 2, spring 3, adjusting nut 4, Cock screw 5, pad 6, flat shoulder grafting head 7, outer cover nut 8.
embodiment:
Adjustable mechanical formula hydraulic pressure safety valve for a kind of shock absorbing chamber, mainly formed by joint 1, steel ball 2, spring 3, adjusting nut 4, Cock screw 5, pad 6, flat shoulder grafting head 7 and outer cover nut 8, it is characterized in that: this shock absorbing chamber adjustable mechanical formula hydraulic pressure safety valve adopts nonstandard joint for being communicated with shock absorbing chamber, at the interior installation of joint 1 steel ball 2 and spring 3, the adjusting nut 4 of capable of regulating amount of spring compression is installed in the end of spring 3.
Described joint 1 material adopts 35 section bar processing; Adopting screw thread 1-1 to be connected with shock absorbing chamber, is 1.6 in the surperficial 1-2 roughness that matches, and 2 fitting surface 1-3 adopt 45 ° of chamferings with steel ball, and roughness is 3.2.
In conjunction with Fig. 1 explanation, the decrement of spring 3 is adjusted in this shock absorbing chamber by adjusting nut 4 with adjustable mechanical formula hydraulic pressure safety valve, thereby set the working value of adjustable mechanical formula hydraulic pressure safety valve, and then guarantee that by the action of safety valve shock absorbing chamber pressure is constant, thereby reach the object that improves relief valve control accuracy.
In conjunction with Fig. 1 explanation, for this shock absorbing chamber, the steel ball 2 adopting in adjustable mechanical formula hydraulic pressure safety valve, flat shoulder grafting head 7 and outer cover nut 8 all adopt ship mark CB 56-1983, improve versatility.
In conjunction with Fig. 2 explanation, described joint 1 material adopts 35 section bar processing.Adopt screw thread 1-1 to be connected with shock absorbing chamber, and guarantee 1.6 in the surperficial 1-2 roughness that matches, in order to guarantee to install sealing, 2 fitting surface 1-3 adopt 45 ° of chamferings with steel ball, roughness 3.2, adopts screw thread 1-4 to be connected with adjusting nut 4, adopts screw thread 1-5 to be connected with outer cover nut 8.
