Abstract
The utility model relates to a high-leakproofness stainless steel water meter with varying-pitch threads. The high-leakproofness stainless steel water meter is characterized by comprising a water meter cylinder (1), a water meter cover connecting position (2) is arranged at the upper portion of the water meter cylinder (1), and varying-pitch thread rings are arranged on the outer wall of the water meter cover connecting position (2). According to the high-leakproofness stainless steel water meter with the varying-pitch threads, the structure is compact, the using performance is improved, and the service life is prolonged.
Description
Technical field
The utility model relates to a kind of stainless steel water meter, relates in particular to a kind of high leakproofness stainless steel water meter with variable pitch screw.
Background technology
Water meter of the prior art is all iron or aluminum, and iron getting rusty easily destroyed water quality, and serviceable life while is low, often change, once destroy, just causes water resource waste serious.
The interface of water meter is all common cylinder screw thread, and straight thread exists gap when screwing, and causes deficiency in use.
Chinese patent 201120270327.2, a kind of stainless steel water watchcase is disclosed, it is characterized in that: it comprises a housing of being made by stainless steel material, this housing is integral type structure, the inside of this housing forms the watch core accommodating cavity of an opening upwards, the leftward position of corresponding described watch core accommodating cavity is provided with an outlet part being connected with this watch core accommodating cavity in the lateral wall of described housing, and the right positions of corresponding described watch core accommodating cavity is provided with a water entering section being connected with this watch core accommodating cavity in the lateral wall of described housing.There is gap in the joint of this structure, interlock completely causes and uses inconvenience.
Utility model content
The utility model is mainly to solve the deficiencies in the prior art, and a kind of compact conformation is provided, and improves the sealing property of water meter simultaneously, makes it to have the high leakproofness stainless steel water meter with variable pitch screw of better resistance to pressure.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals:
A kind of high leakproofness stainless steel water meter with variable pitch screw, comprise water meter cylindrical shell, the top of described water meter cylindrical shell is provided with water meter cover connecting position, the outer wall of described water meter cover connecting position is provided with variable pitch screw circle, described water meter cover connecting position is provided with the water meter cover of bolt with it, the two side ends of described water meter cylindrical shell is respectively equipped with and is attached thereto logical water meter interface, the bottom of described water meter cylindrical shell is provided with the Watermeter base fixing with it, and the outer end of described water meter interface is provided with varying pitch interface thread circle.
As preferably, the thread size of described varying pitch interface thread circle is M32, and pitch maximum in described varying pitch interface thread circle is 2.3mm, and in described varying pitch interface thread circle, adjacent pitch reduces by 0.05～0.15mm.
As preferably, the thread size of described variable pitch screw circle is M80, and pitch maximum in described variable pitch screw circle is 2mm, and in described variable pitch screw circle, adjacent pitch reduces by 0.05～0.15mm.
As preferably, between described water meter cover connecting position and water meter cylindrical shell, be provided with web member, the outer rim of described web member is inner concavity, in described water meter cylindrical shell, is provided with watch core packing ring.
Therefore, the high leakproofness stainless steel water meter with variable pitch screw of the present utility model, compact conformation, improves usability, promotes serviceable life.
