Description

The push type plunger valve

The utility model relates to a kind of valve, specifically a kind of push type plunger valve.

Being used for gas liquid at present carries the valve kind of control a lot, be to use short, fragile, easy to leak of life-span as its main deficiencies such as butterfly valve gate valve stopcocks, when especially using as resident's household tap water valve, often opening valve finds to cut off the water and forget valve is closed again, do not see again when leaving that valve opens or close, among the manager nobody the time water suddenly again, cause a large amount of wastes of water resources, also generally do not promoted the use of because of high difficult installation of complex structure cost though there is the people also to design various self-closing valves.

The purpose of this utility model provides a kind of no seepage and no leakage easy to install simple in structure and can show that valve is that to open be the push type plunger valve that closes.

The purpose of this utility model mode of clicking realizes, depression bar is installed on top at valve casing, plunger is installed in the valve casing and and running water pipe join, the valve plug of the mounting strap axis of guide in plunger, and the lower end and the valve casing of the axis of guide fixed, when rotating forward, depression bar just drives valve casing and the valve plug circulation road of fetching boiling water that moves up, when depression bar rotates backward again, promoting moving valve casing and valve plug by Returnning spring moves down and closes flow channel, the flow of current size is that angle by depression bar rotates backward forward decides with closing, and the very directly perceived and normal phase uses and rust can not occur and stubbornly refuse to close and wait solid the barrier.

Figure of description is the structural representation of push type plunger valve;

Press type plunger valve of the present utility model is done following detailed with reference to Figure of description Carefully illustrate.

Its structure of press type plunger valve of the present utility model be by spool, valve casing [4], Plunger [9], valve plug [5], depression bar form, and spool is installed in the centre of valve casing [4], Spool and running water pipe [13] join. Valve casing [4] be by depression bar, pressure shaft [12], Loam cake [3], spring [8] and valve plug fixed mount [7] form, and loam cake [3] is installed in valve The top of shell [4], depression bar is fixed on the loam cake [3] by pressure shaft [12], and valve plug is fixed Frame [7] is located at the bottom of valve casing [4], and spring [8] is installed on the inwall of valve casing [4], Upper end and the plunger of spring [8] join, and lower end and valve casing [4] join, the side of valve casing [4] Face has opening [19] protruding by tube coupling [10] and that can move up and down. Valve casing [4] depression bar on is made up of handle [16], big plush copper [1], small convex head [17], and is big Plush copper [1], small convex head [17] all are located at handle [16] take pressure shaft [12] as the axle center The end, big plush copper [1] is upwards perpendicular with handle [16], and small convex head [17] then is positioned at handle The end of handle [16]. Spool be by plunger [9], tube coupling [10], pipe joint [15], Pulley [7], pulley bracket [11], valve plug [5] and valve plug guiding trestle [18] form, Two pulleys [2] are installed on the pulley bracket [11], and pulley bracket [11] is located at plunger [9] top, tube coupling [10] become an angle of 90 degrees and plunger [9] top to join tube coupling [10] Protruding from the opening [19] of valve casing [4] side, the tube coupling that stretches out [10] is by pipe Joint [15] adds rubber cushion [14] and running water pipe [13] joins. Valve plug [5] is installed in post The centre of plug [9], the center of valve plug [5] is equipped with the valve plug axis of guide [6], the valve plug guiding Axle [6] passes in the middle of the valve plug guiding trestle [18], the lower end of the valve plug axis of guide [6] and The valve plug fixed mount [7] of valve casing [4] bottom fixes.

Embodiment: the making of push type plunger valve of the present utility model is carried out with shown in the installation by specification accompanying drawing.Concrete working procedure is such when depression bar is the axle center rotation with the pressure shaft, small convex head on the depression bar, big plush copper is pressed on the pulley of plunger head successively, because plunger and running water pipe fix, so the result on big acting on of the small convex head wheel lifts valve casing, again since valve plug and valve casing link, so valve casing lifts valve plug and opens, the distance that valve plug lifts is decided by the big small convex head on the valve rod, also determined simultaneously the size of water flow, the effect of spring is to make valve casing answer head downwards, also determined simultaneously the size of water flow, the effect of spring is that valve casing is resetted downwards, because closing of valve plug is to move down, so the big more sealing of hydraulic pressure is good more, and the dead phenomenon of can not becoming rusty.This plunger valve is compared with prior art to have simple in structure easy to usely, closes from showing, and advantages such as no seepage and no leakage have good value for applications.
