Aiming at the defects existing in the prior art, the utility model aims to provide the PPR ball valve which is more stable in structure and good in sealing performance.
In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides a integrative PPR ball valve of sealed case valve rod of screw fastening, includes valve body, integral type case valve rod, handle, screw, handle block the valve body with integral type case valve rod both sides be equipped with the sealing ring handle and valve body and integral type case valve rod junction have the valve body seal groove the valve body seal inslot be provided with the valve body sealing gasket the handle top be provided with handle block recess handle top recess center department be provided with screw fastening special hole the handle bottom be provided with semicircle half planar valve rod interface the valve rod part of integral type case valve rod be two pairs of arcwall faces and two pairs of plain noodles.
By adopting the technical scheme: the handle has strong integrity, thereby improving the durability of the handle; the integral valve core and valve rod has strong integrity, thereby improving the durability of the valve core and valve rod; the screw tightness is strong, so that the tightness of the handle pressing valve body sealing gasket is improved.
The utility model is further provided with: the handle is heated to a softening state through high temperature, the handle is arranged on the integrated valve core valve rod in the softening state, and after the handle is cooled, the handle and the integrated valve core valve rod are fastened through screws, so that the handle is tightly pressed against the valve body sealing gasket.
By adopting the technical scheme: the handle is cooled and then is tightly attached to the valve rod of the integrated valve core under the characteristics of shrinkage and hardness, so that the condition that a screw is driven to influence the screw fastening effect when the handle is rotated is effectively prevented, and after the screw is fastened, the handle is pressed against the sealing gasket of the valve body, so that the stress of the sealing gasket is increased and the sealing groove is uniformly opened and sealed.
The utility model is further provided with: after the valve rod of the integrated valve core and the sealing rings on two sides are assembled, the valve rod is placed into a PPR injection molding machine and is installed into a valve body through high-pressure injection molding in a valve body die, and a valve body sealing groove is formed at the joint of the valve body and the valve rod part and integrally formed with the valve body.
By adopting the technical scheme: the sealing ring is firmer and clings to the valve rod and the valve body of the integrated valve core, the sealing groove of the valve body is integrated with the valve body, so that gaps are reduced, and the sealing performance is better and more durable.
The utility model is further provided with: the screw is screwed up through the special hole of screw fastening and reduces the gap between handle and the valve rod of integral type case to compress tightly the valve body sealing gasket and make the valve body reach sealedly, use the handle lid to seal the screw in the handle lid recess, if receive external force to influence the handle lid and drop, can repeat the step and install again, do not influence the valve body leakproofness.
By adopting the technical scheme: the screw is difficult to contact with liquid, is more corrosion-resistant and durable, and the handle cover cap only participates in the effect of protecting the screw, does not influence the sealing property of the valve body sealing gasket, can be installed again after the handle cover cap is taken off, and the defect that the sealing property of the valve body sealing gasket is damaged after the handle cover cap of the old-fashioned ball valve is taken off is improved.
