Embodiment Construction

[0043] Please check Figure 1 to Figure 13 , the fixed type double-by-order ball valve, including the valve body part 10, the control part 20, the anti-loosening mechanism 30 and the locking mechanism 40.

[0044] Please check Figure 1 to Figure 5, the valve body part 10 includes a valve body 11 , two pipe connections 12 , two nuts 13 , a liner 14 and two check rings 15 . The valve body 11 is hollow and formed as a stepped hollow hole with a large front and a small rear. The hollow hole is divided into a large hole and a small hole. The valve body 11 is also provided with a rotating hole that runs through the large hole. The lining 14 has an inner hole; the axis of the inner hole coincides with the axis of the hollow hole; the outer diameter of the inner lining 14 is adapted to the diameter of the large hole of the valve body, and the inner diameter of the inner lining 14 is suitable for the diameter of the small hole of the valve body 11. Matching, the liner 14 is fixed in...

Abstract

The invention discloses a fixed type true union ball valve which comprises a valve body part, a controlling part and an anti-loose mechanism. The valve body part comprises a valve body, two pipe connectors and two nuts. The controlling part comprises a valve element and a valve rod. A lock joint mechanism comprises a rotary knob pull rod and an adjusting rotary knob, wherein the the rotary knob pull rod is sleeved outside the valve rod in a sliding mode and the rotary knob pull rod is not capable of rotating relative to the valve rod, and the adjusting rotary knob is sleeved outside the rotary knob pull rod in a rotating mode; by the cooperation of the adjusting rotary knob and the rotary knob pull rod, the rotary knob pull rod can be driven to slide between a lock joint position and a loosening position by rotating the adjusting rotary knob; the rotary knob pull rod is provided with a clamping jaw extending downwards, the valve body is provided with an end face surrounding the valve rod, multiple clamping grooves are formed in the end face, the lower end of the clamping jaw of the rotary knob pull rod at the lock joint position inserts into the clamping groove in an adaptation mode, and the clamping jaw of the rotary knob pull rod at the loosening position is separated from the clamping groove. The fixed type true union ball valve has the following advantages that the use is safe, misoperation can be avoided, the locating effect is good in full open, half open and closed state, and the fixed type true union ball valve is convenient for clients to adjust water flow.

Description

technical field [0001] The present invention relates to a fixed-type double-order ball valve. Background technique [0002] The existing double order ball valve includes the valve body part and the control part. The valve body part at least comprises a valve body, two pipe joints and two nut caps, the two pipe joints are respectively arranged at the front and rear ends of the valve body, and the two nut caps are respectively screwed on the outer rotating surfaces of the front and rear ends of the valve body, The valve body and the pipe joint are sealed and fixed together by screwing the nut on the valve body. The control part includes a valve core and a valve stem, the valve core can be rotatably arranged in the valve body, one end of the valve stem is fixed to the valve core, and the other end extends out of the valve body from the inside to the outside to drive the valve core to rotate through the rotation of the valve stem. Control the water path of the valve body part....
