Abstract

The utility model relates to a leakage proof valve, comprising a valve body, a valve core, a valve rod, a valve bonnet and a handle, wherein, the top of the valve body is sealed by a steel disk and a sealing pad, both sides of the steel disk are provided with permanent magnet rotating disks respectively, both rotating disks are attracted by magnetic force, a plurality of rollers are arranged on the interface of the rotating disks and the steel disk, the valve rod is connected with a driving rotating disk of the rotating disks, and the valve core is connected with a driven rotating disk of the rotating disks. When the driving rotating disk is rotated by the function of the handle, the driven rotating disk and the driving rotating disk are rotated synchronously by the magnetic force, so the valve core is driven to rotate in order to open the valve or close the valve. Because the upper part of the valve body is closed, and the valve rod and the valve core are separated, no leak is from the periphery of the valve rod.

Description

Fully sealing leakage proof valve

The utility model relates to a kind of totally-enclosed leakproof valve.

Common valve generally includes each parts of valve body, spool, valve rod, bonnet and handle; existing this valve seal performance is difficult to guarantee; as the air valve of cylinder for liquefied gas, the gap location regular meeting between valve rod and bonnet such as water valve leaks air or water leakage phenomenon from the beginning; very dangerous, also cause waste.

The purpose of this utility model provides a kind of totally-enclosed leakproof valve, and spool is enclosed in the valve body, thoroughly solves the leakage problem of valve.

The totally-enclosed leakproof valve of the utility model comprises valve body, spool, valve rod, bonnet and handle, the valve body top is with steel disk and sealing gasket sealing, the both sides of steel disk are respectively equipped with a permanent magnet rotating disk, two rotating disk magnetic force are inhaled mutually, and with the steel disk interface on be respectively equipped with several balls, valve rod with wherein initiatively rotating disk link to each other, spool links to each other with driven rotating disk wherein.When needing switch valve, rotatable handle, valve rod promptly drive initiatively rotating disk rotation, because the magnetic force interattraction rotates lower rotary table and top rotary table synchronously, reach the purpose of switch valve.

This valve separates with valve rod because the valve body top is sealed with steel disk, and spool is in the valve body, thereby no refrigerant leakage in the valve rod peripheral clearance, has thoroughly solved the valve leak problem.

Below in conjunction with description of drawings embodiment of the present utility model.

Fig. 1 and Fig. 2 are two example structure figure of the totally-enclosed leakproof valve of the utility model.

As Fig. 1 and Fig. 2, the totally-enclosed leakproof valve of the utility model is made up of valve body 8, spool 7, valve rod 2, bonnet 5 and handle 1, the valve body top is with steel disk 10 and sealing gasket 9 sealings, sealing gasket is that the cross section is the rubber ring of ∏ shape, steel disk 10 permanent magnet initiatively rotating disk 4 and the driven rotating disk 6 of permanent magnet arranged respectively up and down, be equipped with ball 11 on they and the steel disk interface, with the power of reducing friction, two rotating disks are pegged graft with square notch and valve rod and spool respectively.When handle with sleeve 1, initiatively rotating disk 4 rotations, driven rotating disk 6 rotates synchronously because of magnetic attraction and top rotary table, and drives spool and rotate and drive valve or close valve.Among Fig. 1 embodiment, the rotation of spool 7 produces elevating movement, and when spool descended, the import A of valve was closed, and when spool rose, import A opened, and working medium (as liquid gas) is from outlet B output.Among Fig. 2 embodiment, the upper end of spool 7 is provided with stage clip 12, and it makes the spool axial restraint, can only rotate, no lifting displacement, spool has through hole 13, and during shown position, import and export A, the B of through hole and valve are obstructed, valve cuts out, when spool revolve turn 90 degrees after, through hole and valve are imported and exported and are communicated opening of valves.In Fig. 2 example, valve rod also links to each other with timer 3, and it can make the valve automatic timing close.

Claims

1, totally-enclosed leakproof valve, comprise valve body, spool, valve rod, bonnet and handle, it is characterized in that the valve body top is with steel disk and sealing gasket sealing, the both sides of steel disk are respectively equipped with a permanent magnet rotating disk, two rotating disk magnetic force are inhaled mutually, and with the interface of steel disk on be respectively equipped with several balls, valve rod with wherein initiatively rotating disk link to each other, spool links to each other with driven rotating disk wherein.

2, totally-enclosed leakproof valve as claimed in claim 1 is characterized in that said sealing gasket is that the cross section is the rubber ring of ∏ shape.
