Background technique
Reduction valve is the outlet pressure that inlet pressure is reduced to a certain needs through regulating, and relies on the energy of medium itself, makes outlet pressure keep stable valve automatically.See that from hydromechanical viewpoint reduction valve is a throttle element that local resistance can change, promptly through changing orifice size; The kinetic energy of flow velocity and fluid is changed; Cause the different pressure losses, thereby reach the purpose of decompression, rely on the adjusting of control and regulating system then; The fluctuation and the spring force of downstream pressure are balanced each other, make downstream pressure in certain margin of error, keep constant.Present reduction valve mainly contains and utilizes piston enforcement flow control and utilize diaphragm to implement two big types of pressure control, utilizes the piston control flow rate, and along with the reduction of air pressure, the output flow of fluid can reduce thereupon, the poor stability of flow; Use the diaphragm pilot pressure, though flow output is more stable, the life-span of diaphragm is short, and shock resistance is poor.
The model utility content
In order to overcome the defective of existing technology, provide that the output of a kind of flow is stable, long service life, throttle element applied widely, the utility model discloses a kind of gas piston pressure regulation reduction valve.
The utility model reaches goal of the invention through following technological scheme:
A kind of gas piston pressure regulation reduction valve comprises valve body, valve gap, oxo bridge body, air outlet adapter, high pressure gauge and safety valve, and an end of valve body has control hole; The aperture of control hole covers sealing with valve gap, and control hole connects respectively and connects oxo bridge body, air outlet adapter and safety valve, and the outlet side of high pressure gauge and oxo bridge body connects and is connected; It is characterized in that: also comprise pressure regulation bar, pressure regulation masthead cover, pressure adjusting spring, Spring pad, piston, valve inside, valve spring, valve seat and filter cotton, the pressure regulation bar is inserted in the valve gap, and the outer side surface of pressure regulation bar is with pressure regulation masthead cover; The pressure adjusting spring hoop is at the outer side surface of pressure regulation masthead cover; One end of pressure adjusting spring props up the bottom surface of pressure regulation masthead cover, and the other end of pressure adjusting spring is through the bottom surface of Spring pad connection piston, and valve inside is located at the perforation joint of oxo bridge body and control hole; One end of valve inside connects the upper bottom surface of piston; Valve inside is located on the valve seat through valve spring, and valve seat is fixed on the bottom of control hole, and the bottom of valve seat is provided with filter cotton.
Described gas piston pressure regulation reduction valve is characterized in that: the control hole of air outlet adapter and valve body is through being threaded, and said screw thread is selected the G1/4 screw thread for use, and promptly external diameter is 13.158mm, and internal diameter is 11.446mm, and pitch is 1.337mm, and per inch contains 19 teeth.
When the utility model uses; Pressurized gas is exported from oxo bridge body air outlet adapter from the left side after the utility model throttling of right-hand member; Pass through pressure adjusting spring and Spring pad regulating piston by the pressure regulation bar; Pass through valve spring and regulating piston by valve inside, thereby obtain the gas output of stability of flow at air outlet adapter one end.The utility model has overcome piston controlled type instability of flow and diaphragm controlling type short defective in working life, and the beneficial effect of the utility model is: simple in structure, easy to use, flow output is stable, and long service life is applied widely.
