Abstract

The utility model relates to a double-direction sealed valve. The existing sealed valve needs to arrange a sealed arrangement between the rotary work piece and the valve body, which has a complicated structure, poor sealing effect, high manufacturing cost and a large quantity copper material consumption. The utility model is characterized in that the double-direction sealed valve is provided with a flexible elastic bidirectional sealed valve bowl, which can completely isolate the actuating medium from the rotating work piece, and simultaneously has the function of valve opening and valve closing. The utility model has the advantages of high reliability, low cost, and convenient maintenance, and which is suitable for the liquid valve and the gas valve.

Description

Double-way sealed valve

The utility model relates to a kind of two way sealed valve that is used for liquid, gas.

Sealed valve of the prior art needs to be provided with specially seal arrangement between rotary work spare and valve body.Complex structure, and sealing is poor, needs to consume a large amount of copper materials.The manufacture cost height.

The purpose of this utility model is to provide a kind of being equipped with that rotary work spare and liquid, the gas carried are isolated fully, can close again, the valve of the telescopic elastic two way sealed valve bowl of Open valve.

The scheme that technology solves is: bonnet [3] is processed with 2 road internal threads.One internal thread is in order to connect with valve body [10], and one internal thread cooperates with axostylus axostyle [2].Axostylus axostyle [2] upper end is one handle [1] fixedly, and handle with sleeve [1] can make axostylus axostyle [2] rotate up and down.The garden cylindricality guide rod [7] that axostylus axostyle [2] lower end has a garden cylindrical hole [5] and hemisphere spool [8] top is slidingly matched.Hemisphere spool bottom is a hemisphere, and top is garden cylindricality guide rod.The annular edge of pushing down a telescopic elastic two way sealed valve bowl [6] upper end between bonnet [3] and the valve body [10] isolates liquid, gas and rotary work spare along [4] fully.Valve bowl [6] is radially cut open along it, and its section is circular; Vertically cut open along it, its section is a U-shaped.When rotating valve shaft [2], telescopic elastic two way sealed valve bowl [6] is pressed on the sphere [9] of valve body [10] throttle down by hemisphere spool [8].

Adopt telescopic elastic two way sealed valve bowl,, can not produce corrosion workpiece because rotary work spare is isolated fully with liquid, the gas carried.Admittedly can adopt general material to replace copper material.And valve body piece and manufacturing procedure all can reduce, and be simple in structure, and sealing is reliable, can reduce manufacture cost.

Accompanying drawing has been described an embodiment of the present utility model.Bonnet [3] is processed with 2 road internal threads, one internal thread is in order to connect with valve body [10], one internal thread cooperates with axostylus axostyle [2], and axostylus axostyle [2] upper end is one handle [1] fixedly, and handle with sleeve [1] can make axostylus axostyle [2] rotate up and down.The cylinder guide [7] that axostylus axostyle [2] lower end has a cylindrical hole [5] and hemisphere spool [8] top is slidingly matched.Hemisphere spool bottom is a hemisphere, top is to push down the annular edge of a telescopic elastic two way sealed valve bowl [6] upper end between cylinder guide bonnet [3] and the valve body [10] along [4], and liquid, gas and rotary work spare are isolated fully.Valve bowl [6] is radially cut open along it, and its section is circular, vertically cuts open along it, and its section is a U-shaped.When rotating valve shaft [2], telescopic elastic two way sealed valve bowl is pressed on the sphere [9] of valve body [10] throttle down by hemisphere spool [8].When upwards rotating valve shaft [2], telescopic elastic two way sealed valve bowl [6] dependence elasticity and liquid, gas pressure reinstatement, the purpose of realization Open valve.

Claims

1, a kind of two way sealed valve is characterized in that:

Bonnet [3] is processed with 2 road internal threads.One internal thread is in order to connect with valve body [10], and one internal thread cooperates with axostylus axostyle [2].Axostylus axostyle [2] upper end is one handle [1] fixedly, and handle with sleeve [1] can make axostylus axostyle [2] rotate up and down.The cylinder guide [7] that axostylus axostyle [2] lower end has a cylindrical hole [5] and hemisphere spool [8] top is slidingly matched.Hemisphere spool bottom is a hemisphere, and top is cylinder guide.The annular edge of pushing down a telescopic elastic two way sealed valve bowl [6] upper end between bonnet [3] and the valve body [10] isolates liquid, gas and rotary work spare along [4] fully.Valve bowl [6] is radially cut open along it, and its section is circular; Vertically cut open along it, its section is a U-shaped.When rotating valve shaft [2], telescopic elastic two way sealed valve bowl [6] is pressed on the sphere [9] of valve body [10] throttle down by hemisphere spool [8].
