Abstract
The utility model discloses a clamped joint ball valve, which comprises a valve body (1), a valve seat (2), a valve ball (3), a valve rod (4) a knob (5) and loose joint nuts (7) on both ends of the valve body, and is characterized in that the hollow thin wall hoops (6) are provided on the inner mouth of both ends of the valve body (1), and the screws of the loose joint nuts (7) on both ends of the valve body are facing towards the inner side and are screwed with the valve body (1). The clamped joint ball valve is advantageous in that by using loose joint nut internally pressing against hollow thin wall hoop, the ball valve is tightly connected with external pipes, which solves the installation problem of connecting a ball valve in a non-threaded pipe wall or a pipe that can not be threaded.
Description
Technical field:
The utility model relates to a kind of ball valve, relates in particular to the linkage structure at ball valve two ends, specifically is a kind of clamp band type joint ball valve.
Background technique:
Traditional tap water pipe line and air delivering pipeline generally all are metal tubes, and therefore, the valve that connects at its pipeline all adopts thread connecting mode, and this is because the tube wall of metal tube is thicker, can be with the tapping cutter at pipe connecting end tap out silk, conveniently to be spirally connected.But along with development of science and technology and country is energy-saving and cost-reducing and the requirement of the technical policy of low-carbon (LC) life, develop a lot of thin-wall metal pipes, and with the pvc pipe of moulding Dai Gang, plastic-aluminum pipe etc., the characteristic of these pipes, be can not tap out on its tube wall, that is to say that waterway pipe or the gas pipeline formed with these pipes just can not adopt the mode that is spirally connected to come mounted valve, must seek Placement in addition.As the ball valve of very important in the pipeline and a large amount of uses, the screw connection structure at its two ends must thoroughly change, to adapt to the requirement of new piping material.
The model utility content:
The technical problems to be solved in the utility model is, how to make ball valve not have screw thread or tube wall not to carry out connection in the pipeline of tapping at tube wall, and a kind of clamp band type joint ball valve is provided.
Technical solution of the present utility model is:
Clamp band type joint ball valve, the loose joint nut that comprises valve body, valve seat, valve ball, valve rod, knob and valve body two ends, it is characterized in that be respectively arranged with the hollow thin-wall hoop on the internal orifice of described valve body two ends, the screw socket of the loose joint nut at described valve body two ends is spirally connected with described valve body inwardly.
The utility model clamp band type joint ball valve with the principle that pipe in the pipeline is connected is, external tube passed loose joint nut mesopore and be plugged in the hollow thin-wall hoop in the valve body, then the loose joint nut is tightened on the valve body, make hollow thin-wall hoop stress deformation by loose joint nut inward turning, externally connected pipe tightly is pressed in the hollow thin-wall hoop, externally connected pipe and ball valve are connected firmly and can not become flexible and come off.
After adopting above structure, compared with prior art, the utlity model has following advantage: owing to adopted the mode of pressing the hollow thin-wall hoop in the loose joint nut on the ball valve, ball valve and external pipe fitting connected securely, solved the problem that ball valve does not have screw thread or tube wall to carry out connection in can not the pipeline of tapping at tube wall preferably.
As improvement, the end face of described hollow thin-wall hoop is arranged to male cone (strobilus masculinus).The end face of hollow thin-wall hoop is arranged to bore the inclined-plane, more can makes the loose joint nut that the hollow thin-wall hoop is balancedly compressed interior receipts, it is more well-balanced and the externally connected pipe distortion is lost shape to make external pipe fitting connect power.
Description of drawings:
Accompanying drawing is the utility model clamp band type joint ball-valve structure schematic representation.
Shown in the figure: 1, valve body, 2, valve seat, 3, valve ball, 4, valve rod, 5, knob, 6, the hollow thin-wall hoop, 7, the loose joint nut.
Embodiment:
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
Shown in the accompanying drawing, the utility model clamp band type joint ball valve, the loose joint nut 7 that comprises valve body 1, valve seat 2, valve ball 3, valve rod 4, knob 5 and valve body two ends, it is characterized in that, be respectively arranged with hollow thin-wall hoop 6 on the described valve body 1 two ends internal orifice, the screw socket of the loose joint nut 7 at described valve body two ends is spirally connected with described valve body 1 inwardly.
The end face of described hollow thin-wall hoop 6 is arranged to male cone (strobilus masculinus).
When installation makes, external tube passed loose joint nut 7 center holes and be plugged in the hollow thin-wall hoop 6 on the internal orifice of valve body two ends, then loose joint nut 7 is tightened on the valve body 1, make hollow thin-wall hoop 6 stress deformations by loose joint nut 7 inward turnings, externally connected pipe is pressed in the hollow thin-wall hoop 6, externally connected pipe and ball valve are connected firmly and can not become flexible and come off.
Claims (2)
1. clamp band type joint ball valve, the loose joint nut (7) that comprises valve body (1), valve seat (2), valve ball (3), valve rod (4), knob (5) and valve body two ends, it is characterized in that: be respectively arranged with hollow thin-wall hoop (6) on the internal orifice of described valve body (1) two ends, the screw socket of the loose joint nut (7) at described valve body (1) two ends is spirally connected with described valve body (1) inwardly.
2. clamp band type joint ball valve as claimed in claim 1 is characterized in that: the end face of described hollow thin-wall hoop (6) is arranged to male cone (strobilus masculinus).
