Abstract
The utility model relates to a self-pressing and self-sealing valve which is mainly composed of a valve cover, a step, a threaded rod, a movable sealing ring, a valve body, external connecting screw threads, a water outlet hole, a fixing sealing ring, a water inlet hole, a sealing plate or a cone, and a floating block. The pressure difference of the liquid or liquid in the valve body and the water outlet hole is generated through upwards lifting or downwards pushing a draw rod. The utility model has the advantages of self pressing, self sealing, simple structure, small mechanical wear, good sealing performance, no water leakage, low cost, and long service life.
Description
The utility model belongs to valve, pressure self-enclosed valve especially, and what be applicable to liquid or gas seal pipeline opens the valve occasion.
Before the utility model is made, the valve of prior art is mainly by valve gap, step, screw rod, exterior seal ring, valve body, external connection screw, osculum, fixed seal ring, the water inlet is formed, valve body and valve gap are usually by threaded joint, exterior seal ring is fixed on the screw rod, the screw rod lower end is provided with sealing plate, screw rod and valve gap threaded joint, exterior seal ring is positioned at the step upper end, fixed seal ring is arranged on the osculum place of valve body, the water inlet, osculum is respectively by screw thread and intake pipe, outlet pipe links, liquid or gas enter from the water inlet of intake pipe, screw rod rotates up along the valve gap screw thread, and sealing plate separates with seal ring, and liquid or gas enter outlet pipe along osculum, screw rod is rotated down along valve gap, sealing plate compression seal circle sealing osculum.Its major defect is to open and close difficulty, and mechanical wear is big, and fixed seal ring and exterior seal ring are easy to wear, and working life is short, easily leaks.
Task of the present utility model is the shortcoming that overcomes prior art, provides a kind of simple and reasonable, opens and closes easily, and mechanical wear is little, good seal performance, the pressure self-enclosed valve of long service life.
Pressure self-enclosed valve of the present utility model, mainly by pull bar 1, valve gap 2, step 3, movable sealing circle 4, valve body 5, external connection screw 6, osculum 7, fixed seal ring 8, water inlet 9 and sealing plate 10, cone 11, floating block 12 is formed or mainly by pull bar 1, valve gap 2, step 3, movable sealing circle 4, valve body 5, external connection screw 6, osculum 7, fixed seal ring 8, water inlet 9 is formed, valve body 5 and valve gap 2 are by threaded joint, movable sealing circle 4 is enclosed within and is positioned at step 3 bottoms on the pull bar 1, pull bar 1 bottom is provided with sealing plate 10 or sealing plate 10 is not set, when pull bar 1 bottom is not provided with sealing plate 10, pull bar 1 bottom is provided with cone 11, floating block 12 is arranged between cone 11 and the fixed seal ring 8, the center line of the center line of cone 11 and floating block 12 center holes is on same straight line, fixed seal ring 8 is arranged on osculum 7 places of valve body 5, water inlet 9, osculum 7 is respectively by external connection screw 6 and intake pipe, outlet pipe connects.
Fig. 1, Fig. 2 are the pressure self-enclosed valve structural representation.
1-pull bar wherein, 2-valve gap, 3-step, 4-movable sealing circle, 5-valve body, 6-external connection screw, 7-osculum, 8-fixed seal ring, 9-water inlet, 10-sealing plate, 11-cone, 12-floating block.
Fig. 1, Fig. 2 is embodiment of the present utility model, as shown in Figure 1, when liquid or gas pressure hour, working principle of the present utility model and embodiment are: by pull bar 1, valve gap 2, step 3, movable sealing circle 4, valve body 5, external connection screw 6, osculum 7, fixed seal ring 8, water inlet 9, the pressure self-enclosed valve that sealing plate 10 is formed, valve body 5 and valve gap 2 are by threaded joint, movable sealing circle 4 is enclosed within and is positioned at step 3 bottoms on the pull bar 1, pull bar 1 bottom is provided with sealing plate 10, or sealing plate 10 is not set, fixed seal ring 8 is arranged on osculum 7 places of valve body 5, water inlet 9, osculum 7 is respectively by external connection screw 6 and intake pipe, outlet pipe connects, liquid or gas enter from the water inlet 9 of intake pipe, pull bar 1 upwards draws high together with sealing plate 10, sealing plate separates with fixed seal ring 8, liquid or gas enter outlet pipe along osculum 7, pull bar 1 pushes downwards together with sealing plate 10, movable sealing circle 8 is subjected to the interior liquid of valve body or the pressure effect of gas, make movable sealing circle 4 press step 3, thereby make sealing plate 10 press fixed seal ring 8 sealing osculums 7.As shown in Figure 2, when liquids and gases pressure is big, working principle of the present utility model and embodiment are: by pull bar 1, valve gap 2, step 3, movable sealing circle 4, valve body 5, external connection screw 6, osculum 7, fixed seal ring 8, water inlet 9, cone 11, the pressure self-enclosed valve that floating block 12 is formed, valve body 5 and valve gap 2 are by threaded joint, movable sealing circle 4 is enclosed within and is positioned at step 3 bottoms on the pull bar 1, pull bar 1 bottom is provided with cone 11, floating block 12 is arranged between cone 11 and the fixed seal ring 8, the center line of the center hole of the center line of cone 11 and floating block 12 is on same straight line, fixed seal ring 8 is arranged on osculum 7 places of valve body 5, water inlet 9, osculum 7 is respectively by external connection screw 6 and intake pipe, outlet pipe connects, liquid or the gas water inlet 9 along osculum 7 from intake pipe enters, pull bar 1 upwards draws high together with cone 11, cone 11 is separated with the center hole of floating block 12, small amount of liquid or gas enter outlet pipe by floating block 12 center holes, floating block 12 is subjected to the effect of valve body 5 interior liquid or buoyant gas, floating block 12 separates with fixed seal ring 8, liquid or gas conveniently adjust the water yield by the position that control pull rod 1 upwards draws high, pull bar 1 pushes downwards together with cone 11, cone 11 and the sealing of floating block 12 center holes, floating block is subjected to valve body 5 interior liquid or gas from the pressure effect, floating block 12 and fixed seal ring 8 sealings, liquid or gas pressure increase in the valve body, make movable sealing circle 4 press step 3, thereby make floating block 12 compression seal circles 8 sealing water outlets.
