Description

Integrative PPR ball valve of high sealed leak protection case valve rod

Technical Field

The utility model belongs to the technical field of valve manufacturing, and relates to a ball valve, in particular to a high-sealing leakage-proof valve core and valve rod integrated PPR ball valve.

Background

At present, ball valves are widely used in civil fields and industrial fields such as petroleum and chemical industry. When the device is used for farmland irrigation and equipment, the valve core and the valve rod are easy to separate or break due to repeated opening and closing, the phenomena of damage and water leakage are caused, water resources are wasted, and economic burden is increased.

Disclosure of Invention

Aiming at the defects in the prior art, the utility model aims to provide a PPR ball valve which is simple in structure and good in sealing performance.

In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides an integrative PPR ball valve of high sealed leak protection case valve rod, includes valve body, integral type case valve rod, integral type pressure cap handle valve body and integral type case valve rod both sides be equipped with the sealing ring the integral type press cap handle and valve body, integral type case valve rod junction have a valve body seal groove the valve body seal groove on be provided with valve body seal ring.

By adopting the technical scheme: the integral cap pressing handle has strong integrity, so that the durability of the handle is improved; the valve rod of the integrated valve core has strong integrity, thereby improving the durability of the valve rod of the valve core.

The utility model is further configured to: the cap handle is pressed to the integral type through high temperature heating to softening state, and the cap handle is pressed to the integral type is installed on the integral type case valve rod (there is corrugate connection tongue and groove, two sides plane ripple not on the integral type case valve rod two sides) under the high temperature softening state to compress tightly valve body seal ring.

By adopting the technical scheme: the cooling back of cap handle is pressed to the integral type is inseparabler under shrink and the characteristic of becoming hard and is connected the tongue and groove laminating with the corrugate of integral type case valve rod, with tighter, the big degree improvement leakproofness that valve body seal gasket pressed.

The utility model is further configured to: after the integrated valve core and valve rod and the sealing rings on the two sides are assembled, the integrated valve core and valve rod and the sealing rings on the two sides are placed into a valve body mold for high-pressure injection molding and are integrally formed with a valve body.

By adopting the technical scheme: the sealing ring is firmer, clings to integral type case valve rod and valve body, and the leakproofness is better more durable.

Drawings

FIG. 1 is a schematic structural view of the present invention;

reference numbers in the drawings and corresponding part names: the valve comprises a 1-integrated pressing cap handle, a 2-integrated valve core and valve rod, a 3-valve body, a 4-valve body sealing washer, a 5-sealing ring, a 6-corrugated connecting concave-convex groove and a 7-valve body sealing groove.

Detailed Description

One embodiment of the present invention is further described with reference to fig. 1.

The utility model provides an integrative PPR ball valve of high sealed leak protection case valve rod, includes integral type case valve rod 2, installs sealing ring 5, together put into PPR injection molding machine valve body mould in, mould plastics through PPR high pressure and form valve body 3, with integral type case valve rod 2 and seal ring 5 parcel and rather than tightly laminating, place and cool down and increase hardness.

The valve body 3, the integrated valve core and valve rod 2 and the sealing ring 5 form a whole, and a valve body sealing washer 4 is arranged in a valve body sealing groove 7; carry out high temperature heating to softening back with integral type pressure cap handle 1, install on integral type case valve rod 2 to compress tightly valve body sealing washer 4, cool off the shrink, further compress tightly valve body sealing washer 4 behind the shrink and improve sealed effect.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered by the protection scope of the utility model.
