Description
Technical field:
The utility model relates to a kind of valve that is installed on the pipeline, specifically is a kind of pneumatic control stop valve for flowing medium break-make in the control high pressure pipe line.
Background technique:
At present; on gas pipeline, generally all adopt hand stop valve to control the break-make of gas; and at some Code in Hazardous Special Locations; under poisonous harmful or environment that gas in pipelines pressure is larger; the people closely manual manipulation handle keying of controlling flap have certain danger usually; in addition; when above-mentioned hand stop valve cuts out; the conical section of flap bottom can be inserted in the circular gas-entered passageway on the valve body; the male cone (strobilus masculinus) of conical section will be pressed on the annular corner angle on circular gas-entered passageway Exit-edge edge, thereby circular gas-entered passageway and circular outlet passageway that valve body is provided with disconnect, yet; because the cross section angle of annular corner angle mostly is greatly 90 °; therefore, when conical section was pressed on the annular corner angle, the deformability of annular corner angle was limited; cause between conical section and the annular corner angle poorly sealedly, cause gas leakage.
The model utility content:
The technical problems to be solved in the utility model is, provides a kind of sealability better, and the pneumatic control stop valve that can the telecontrol flap opens and closes.
Technical solution of the present utility model is, provide a kind of pneumatic control stop valve with following structure: comprise valve body and flap, valve body is provided with circular gas-entered passageway and circular outlet passageway, flap is arranged in body cavity, the flap bottom is provided with conical section, the conical section bottom is inserted in the circular gas-entered passageway, and the male cone (strobilus masculinus) of conical section is pressed on the annular corner angle on circular gas-entered passageway Exit-edge edge, wherein, be connected with the long-range air control unit that a control flap opens and closes on the valve body, the cross section angle α of annular corner angle is 60 °～80 °.
A kind of pneumatic control stop valve described in the utility model, wherein, long-range air control unit comprises cylinder, piston and the cylinder head that is connected to cylinder head, the cylinder bottom is connected with valve body, piston is contained in the cylinder inner cavity and with cylinder inner cavity and is divided into upper gas chamber section and lower air chamber section, cylinder head is provided with the upper control channel that communicates with the upper gas chamber section, and the cylinder bottom is provided with the lower control channel that communicates with the lower air chamber section, and piston base passes cylinder and is connected with flap.
A kind of pneumatic control stop valve described in the utility model, wherein, the approach switch that long-range air control unit also comprises induction rod, lining nut, adjusting nut and is used for being electrically connected with controller, the lining nut is connected with cylinder head, adjusting nut is enclosed within on the induction rod and with induction rod and is threaded, be provided with spring between adjusting nut and the lining nut, the induction rod bottom is passed the lining nut and is connected with piston, induction piece is equipped with on induction rod top, and approach switch is positioned at the induction piece below and is connected with cylinder head.
A kind of pneumatic control stop valve described in the utility model, wherein, the cross section angle α of annular corner angle is 60 ° or 65 ° or 70 ° or 75 ° or 80 °.
A kind of pneumatic control stop valve described in the utility model, wherein, the cross section angle α of annular corner angle is 70 °.
After adopting above structure, compared with prior art, the utility model pneumatic control stop valve has the following advantages: from the prior art hand stop valve need people closely the manual manipulation handle to control the keying of flap different, the utility model pneumatic control stop valve comprises a long-range air control unit, therefore, people can control the keying of flap in the situation that pass through this long-range air control unit away from the utility model pneumatic control stop valve, thereby have ensured personal safety.In addition, because the cross section angle of annular corner angle is 60 °～80 °, therefore, when conical section is pressed on the annular corner angle, the deformability of annular corner angle will strengthen greatly, can seal preferably thereby make between conical section and the annular corner angle again.
Upper control channel and lower control channel are respectively with after the external control source of the gas is connected, pass into control gas by upper control channel to the upper gas chamber section, thereby pushing piston moves down, the flap bottom is pressed on the annular corner angle on circular gas-entered passageway Exit-edge edge, realize that circular gas-entered passageway and circular outlet passageway disconnect, on the contrary, pass into control gas by lower control channel to the lower air chamber section, thereby pushing piston moves up, flap and then moves upward, and realizes that circular gas-entered passageway is communicated with circular outlet passageway.Be not difficult to find out by above-mentioned working procedure, the movement of flap is controlled by external control gas, has therefore realized telecontrol.
The effect that approach switch is set is: when circular gas-entered passageway and the disconnection of circular outlet passageway, be after the conical section of flap bottom is pressed on the annular corner angle on circular gas-entered passageway Exit-edge edge, the induction piece on induction rod top will be near approach switch, approach switch obtains signal and this signal is passed to controller, this can make people know that circular gas-entered passageway and circular outlet passageway are in off state, on the contrary, induction piece is during away from approach switch, and controller can point out circular gas-entered passageway and circular outlet passageway to be in on-state to people.
The angle α of 60 ° or 65 ° or 70 ° or 75 ° or 80 ° is the preferred implementation of the utility model pneumatic control stop valve.
70 ° angle α is the preferred forms of the utility model pneumatic control stop valve.
