In the figure: the valve comprises a valve body 1, a liquid inlet channel 2, a valve cover 3, a valve handle 4, a valve rod 5, a sealing bearing seat 6, a first sealing layer 7, a ball body 8, a second sealing layer 9, a liquid inlet hole 10, an exhaust pipe 11, a one-way air valve 12 and a connecting rod 13.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-3, an ultra-low temperature ball valve that floats includes a valve body 1, a liquid inlet channel 2 is arranged in the middle of the valve body 1, and a valve cover 3 is installed on the top end cover of the valve body 1, a valve rod 5 is vertically inserted in the middle of the valve body 1 in a rotating manner, a valve handle 4 is installed and fixed on the top end of the valve rod 5, a sealing bearing seat 6 is installed and fixed in the middle of the valve body 1, and the valve rod 5 is inserted in the middle of the sealing bearing seat 6 in a rotating.
And the bottom installation of valve rod 5 is fixed with spheroid 8, the middle part of spheroid 8 runs through and has seted up feed liquor hole 10, and 8 levels of spheroid rotate and set up in the middle part of inlet channel 2, and the vertical blast pipe 11 that is equipped with of inserting under spheroid 8, threaded hole is seted up under spheroid 8, the threaded hole connects fixedly with the sealed spiral of blast pipe 11, the both sides horizontal installation of 11 bottoms of blast pipe is fixed with connecting rod 13, blast pipe 11 and feed liquor hole 10 intercommunication, and the bottom of blast pipe 11 stretches out valve body 1, the one end installation that blast pipe 11 stretches out valve body 1 is fixed with one-way pneumatic valve 12.
Furthermore, two sides of the middle part of the liquid inlet channel 2 are provided with a first sealing layer 7, and the inner wall of the first sealing layer 7 is in sliding fit with the inner wall of the ball body 8.
Further, the outer side of the exhaust pipe 11 in the valve body 1 is wrapped with a second sealing layer 9, and the exhaust pipe 11 is in sliding fit with the second sealing layer 9.
The first sealing layer 7 and the second sealing layer 9 are both made of silicone, and the first sealing layer 7 and the second sealing layer 9 can be used for sealing well.
In this embodiment, make valve rod 5 drive spheroid 8 at inlet channel 2 internal rotations through rotary valve door handle 4, when feed liquor hole 10 on spheroid 8 and inlet channel 2 communicate, can realize leading to liquid, when feed liquor hole 10 on spheroid 8 and inlet channel 2 do not communicate, block and lead to liquid, thereby can be fine control opening and close inlet channel, also can carry out the regulation of inlet channel 2 flow according to the 10 opening sizes in feed liquor hole 10 when feed liquor hole 10 on spheroid 8 and inlet channel 2 communicate.
When inlet channel 2 pressure crosses low formation gas, 11 discharges of blast pipe under the accessible spheroid 8 intercommunication, through opening one-way gas valve 12 on the blast pipe 11, through opening one-way gas valve 12, the gas escape in inlet channel 2 can in time be avoided to blast pipe 11, and it is too big to avoid the internal gas pressure of valve body 1, appears the potential safety hazard.
