Abstract
The utility model relates to a high-pressure manual stop valve which is usually installed on a pipeline and used for controlling the on-off of a flowing medium flowing in a high-pressure pipeline and comprises a valve body, a valve clack, a gasket, a bracket, a gland flange, a valve rod and a handle, wherein a round air-inlet passage and a round air-outlet passage are arranged on the valve body, the valve clack is positioned in the inner cavity of the valve body, the bottom of the valve clack is provided with a conical segment, the lower part of the conical segment is inserted into the round air-inlet passage, the outer conical surface of the conical segment is tightly pressed on an annular edge on the outlet edge of the round air-inlet passage, the gasket and the bracket are installed in the inner cavity of the valve body, the upper part of the valve clack is rotatably connected with the valve rod after sequentially penetrating through the gasket and the bracket, the gland flange is tightly pressed on the top of the bracket and is connected with the valve body, the lower part of the valve rod is connected with the gland flange through threads, and the upper part of the valve rod is connected with the handle after penetrating through the gland flange, wherein the sectional included angle alpha of the annular edge is 60 to 80 degrees. The high-pressure manual stop valve disclosed by the utility model has better sealing performance.
Description
Technical field:
The utility model relates to a kind of valve that is installed on the pipeline, specifically is a kind of high pressure hand-operated stop valve for flowing medium break-make in the control high pressure pipe line.
Background technique:
Existing high pressure hand-operated stop valve generally comprises valve body, flap, valve rod and handle, valve body is provided with circular gas-entered passageway and circular outlet passageway, and flap is arranged in body cavity, and the flap bottom is provided with conical section, flap top and valve rod are rotatably connected, and valve rod top is fixedly connected with handle.When above-mentioned high pressure hand-operated stop valve is closed, the conical section bottom can be inserted in the circular gas-entered passageway, the male cone (strobilus masculinus) of conical section will be pressed on the annular corner angle on gas-entered passageway Exit-edge edge, thereby gas-entered passageway and outlet passageway are disconnected, 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 that preferably high pressure hand-operated stop valve of a kind of sealability is provided.
Technical solution of the present utility model is, provide a kind of high pressure hand-operated stop valve with following structure: comprise valve body, flap, packing ring, support, gland flange, valve rod and handle, 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, packing ring and support are contained in the body cavity, flap top is passed successively packing ring and support and valve rod and is rotatably connected, gland flange is pressed on a top of the trellis and is connected with valve body, stem lower portion is threaded with gland flange, valve rod top is passed gland flange and is connected with handle, and wherein, the cross section angle α of annular corner angle is 60 °～80 °.
High pressure hand-operated 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 °.
High pressure hand-operated 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 high pressure hand-operated stop valve has the following advantages: 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.
The angle α of 60 ° or 65 ° or 70 ° or 75 ° or 80 ° is the preferred implementation of the utility model high pressure hand-operated stop valve.
70 ° angle α is the preferred forms of the utility model high pressure hand-operated stop valve.
Description of drawings:
Fig. 1 is that the master of the utility model high pressure hand-operated stop valve looks the sectional structure schematic representation;
Fig. 2 is the structure for amplifying schematic representation of " I " among Fig. 1.
Embodiment:
Below in conjunction with the drawings and specific embodiments the utility model high pressure hand-operated stop valve is described in further detail:
