Abstract
The utility model relates to the field of machinery, in particular to a ball valve. A locking ball valve with a polypropylene-random (PPR) joint comprises a locking ball valve, wherein the locking ball valve comprises a valve seat and a locking device; a male interface is arranged at the right end of the valve seat; and a left end port of the valve seat is connected with the PPR joint through a locking nut. By adoption of the technical scheme, the locking ball valve with the PPR joint can freely adjust the length of an operating arm, and is convenient to mount and use, simple in integral structure, convenient to manufacture and low in cost.
Description
Technical field
The utility model relates to mechanical field, is specifically related to a kind of locking ball valve.
Background technique
At present, ball valve has been widely used in the industrial fields such as civil area and oil, chemical industry.In civil area, ball valve has become in people's daily life indispensable controlling component in the water system.
In order to satisfy ball valve Security in use; Occurred the locking ball valve on the market, satisfy performance constraint, but the common sealing of these Locking valves has been relatively poor the valve switch of water system; Can't closely be connected with the PPR pipeline that generally uses now; Cause water leakage phenomenon, both waste water resource increased economic burden again.
The model utility content
The purpose of the utility model is, a kind of locking ball valve of the PPR of being provided with joint is provided, and solves above technical problem.
The technical problem that the utility model solved can adopt following technological scheme to realize:
Be provided with the locking ball valve of PPR joint, comprise a locking ball valve, said locking ball valve comprises a valve seat, locking device, it is characterized in that, said valve seat right-hand member is provided with outer tooth interface, and said valve seat left end port connects a PPR joint through a locking nut.
The utility model is provided with said PPR joint at valve seat one end on the basis of locking ball valve, so design can closely be connected said PPR joint with the PPR pipeline through hot joining technology, improves the locking ball valve to seal for pipe joints property, simplifies installation process.
Said valve seat is the valve seat of a three-port structure; The right-hand member of said valve seat is provided with said outer tooth interface; The left end port of said valve seat connects a PPR joint through a locking nut; Said valve seat comprises that one is positioned at the upper end port of said valve seat top, and the key port of said locking device is positioned at port, said upper end.
Said PPR joint is reducer fitting, and the right-hand member diameter of said PPR joint is greater than said PPR joint left end diameter, so that be fixedly connected said valve body.
The right-hand member port inner diameter of said PPR joint equals the outer diameter of the left end port of said valve seat, the left end port of the said valve seat of right-hand member port socket of said PPR joint.
Said valve seat left end port outer wall is provided with outside thread, and said valve seat left end port is threaded with said locking nut.
Said locking nut left end inboard is provided with a flange; Said flange is an annular flange, and the inner diameter of said annular flange is greater than the left end outer diameter of said PPR joint, so that behind the left end port of the said valve seat of right-hand member port socket of said PPR joint; Left end from the PPR joint is inserted in said locking nut; Compress the joint of said PPR joint and said valve seat through said flange, and be threaded, strengthen this practical new overall tightness with said valve seat.
Beneficial effect: owing to adopt technique scheme, the utility model has improved whole sealing, is convenient to install and use, and overall structure is simple, easy to make, with low cost.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand with effect and understand, below in conjunction with the further elaboration the utility model of concrete diagram.
With reference to Fig. 1, be provided with the locking ball valve of PPR joint, comprise a locking ball valve, the locking ball valve comprises a valve seat 1, locking device, and valve seat 1 right-hand member is provided with outer tooth interface 11, and valve seat 1 left end connects a PPR joint 2 through a locking nut 3.The utility model is provided with a PPR joint 1 at valve seat one end on the basis of locking ball valve, so design can closely be connected PPR joint 1 with the PPR pipeline through hot joining technology, improves the locking ball valve to seal for pipe joints property, simplifies installation process.
Valve seat 1 is the valve seat of a three-port structure; The right-hand member of valve seat 1 is provided with outer tooth interface 11; The left end port of valve seat 1 connects a PPR joint 2 through a locking nut 3, and valve seat 1 comprises that one is positioned at the upper end port of valve seat 1 top, and the key port 12 of locking device is positioned at the port, upper end.So that the locking ball valve is as the tie that is connected between PPR pipe and other pipelines, and flow is controlled in right amount through ball-valve structure.
Valve seat 1 left end port outer wall is provided with outside thread 13, and valve seat 1 left end port is threaded with locking nut 3.Locking nut 3 left end inboards are provided with a flange; Flange is an annular flange, and the inner diameter of annular flange is greater than the left end outer diameter of PPR joint 2, so that behind the left end port of the right-hand member port socket valve seat 1 of PPR joint 2; Left end from PPR joint 2 is inserted in locking nut 3; Compress the joint of PPR joint 2 and valve seat 1 through flange, and be threaded, strengthen this practical new overall tightness with locking nut 3.
More than show and described basic principle of the utility model and the advantage of major character and the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
