A kind of pretightening sealing ball valve device comprises ball valve lower body, spring, sealing metal body, seal ring, ball valve, tooth bar, gear, hydraulic conveying tube, ball valve upper body and clamp-screw composition.The ball valve lower body is connected with the ball valve upper body by clamp-screw, on ball valve upper body and ball valve lower body, be provided with the circular hole of assembling rack and pinion, spring is contained in the bottom of ball valve lower body, sealing metal body and ball valve are contained in the ball valve lower body, be in the spring top, carbon material is laid on sealing metal body and ball valve surface, gear is connected with ball valve by the tooth embedding, rack and pinion meshes by tooth, and tooth bar is fixed on ball valve upper body and the ball valve lower body by the hydraulic conveying tube at two ends, when requiring ball valve work, apply a power by the hydraulic conveying tube transmit fluid to tooth bar, the tooth bar transmitting gear, the gear driven ball valve rotates, and reaches the ball valve closed condition.Owing to be provided with spring in ball valve bottom, ball valve is had from close property, guarantee that the sealing of ball valve is more reliable, improve the feasibility of operation.
Description
Technical field
The present invention relates to a kind of gas hydrates coring operation device, belong to the special operation of new energy exploration and development.
Background technique
The ball valve that carries out the coring operation use at present is by external force ball valve to be closed by the arm of force that is connected with ball valve in the ball valve outside.This structure just need be provided with an outer movable tube in the ball valve body outside if will guarantee that ball valve closes, and it is one differential at first to require urceolus and ball valve body to have when the needs ball valve is closed, and outer weight is closed ball valve.Ball valve pretension function is not set in the ball-valve structure, thus ball valve to close the success rate of pressurize lower, can not satisfy the requirement of actual demand.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of ball valve pretension sealing problem, when using the ball valve operation, ball valve body and heat-insulation pressure keeping tube connect, when the needs ball valve is closed, the signal command mechanism that is provided with in the pressure-maintaining and heat-preservation tube to the fluid pressure of tooth bar in the ball valve, closes ball valve by liquid.The purpose of this invention is to provide a kind of pretightening sealing ball valve device.
For addressing the above problem, a kind of pretightening sealing ball valve device of the present invention comprises ball valve lower body, spring, sealing metal body, seal ring, ball valve, tooth bar, gear, hydraulic conveying tube, ball valve upper body and clamp-screw composition.The ball valve lower body is connected with the ball valve upper body by clamp-screw, on ball valve upper body and ball valve lower body, be provided with the circular hole of assembling rack and pinion, spring is contained in the bottom of ball valve lower body, sealing metal body and ball valve are contained in the ball valve lower body, be in the spring top, carbon material is laid on sealing metal body and ball valve surface, gear is connected with ball valve by the tooth embedding, rack and pinion meshes by tooth, and tooth bar is fixed on ball valve upper body and the ball valve lower body by the hydraulic conveying tube at two ends, when requiring ball valve work, apply a power by the hydraulic conveying tube transmit fluid to tooth bar, the tooth bar transmitting gear, the gear driven ball valve rotates, and reaches the working state that ball valve is closed.Owing to be provided with spring in ball valve bottom, make ball valve have selfsealings, guarantee that the sealability of ball valve is more reliable, improve the feasibility of other operations.
