Example Embodiment

[0011] Such as figure 1 As shown, the precision pressure reducing valve structure of the present invention includes an outer casing 1, a pneumatic valve 5, and a valve body 8. The outer casing 1 is provided with a valve body 8, and both ends of the valve body 8 are connected with an air pump 7, two Each air pump 7 extends into the bottom side of the inner core of the valve body 8 and is connected to the lower sealing plate of the valve. The top side of the outer housing 1 is installed with the upper sealing plate 3 through a number of tightening bolts 2; the middle of the valve body 8 is provided with an adjusting plate transversely 9 and its two sides are close to the two side walls of the valve body 8. The adjusting plate 9 is provided with adjusting bolts 6, the upper part of the adjusting plate 9 is provided with a pneumatic valve 5, and a sliding knob 4 is movably connected to the top of the adjusting plate 9. A certain cavity is provided between the upper sealing plate 3 ...

Abstract

The invention discloses a precision pressure reducing valve structure, which comprises an outer shell, an upper sealplate, a pneumatic valve and a valve body, wherein the valve body is arranged in the outer shell; the two ends of the valve body are communicated with air pumps; the two air pumps extend into the bottom side of an inner disk of the valve body and are connected with a lower sealplate in the valve; the top of the outer shell is provided with the upper sealplate through a plurality of screwing bolts; the middle of the valve body is horizontally provided with an adjusting plate, and the two sides of the adjusting plate are closely attached to the two side walls of the valve body; the adjusting plate is provided with an adjusting bolt; the upper part of the adjusting plate is provided with the pneumatic valve, and the top of the pneumatic valve is movably connected with a sliding knob; and a certain cavity is formed between the sliding knob and the upper sealplate. The precision pressure reducing valve structure has the advantages that: the pressure behind the valve can be kept in a certain range, and appliances for life and production behind the valve are protected under the condition that the inlet pressure is constantly changed; and when reverse buckling connection is performed or an upper pressure reducing valve is aligned, a hand wheel can be smoothly rotated in the reverse buckling direction, and the precision pressure reducing valve structure has high air tightness.

Description

technical field [0001] The invention relates to a device capable of regulating fluid flow, in particular to a structure of a precision pressure reducing valve. Background technique [0002] Pressure reducing valves generally control the opening of the opening and closing parts in the valve body to adjust the flow of the medium, reduce the pressure of the medium, and at the same time adjust the opening of the opening and closing parts with the help of the pressure behind the valve to keep the pressure behind the valve within a certain range , in the case of constant changes in the inlet pressure, keep the outlet pressure within the set range to protect subsequent living and production appliances. Existing decompression valve and angle valve are connected with anti-locking, when the pressure-reducing valve is put on, it must be aligned first, and then the handwheel is rotated in the anti-clockwise direction (counterclockwise), and its airtightness is poor.
