A high-pressure direct-flow stop valve

Abstract

The invention discloses a high-pressure oblique stop valve. The valve structurally comprises a valve body, a connecting flange, a controller, buttons, a display screen, a power lead, a fixing frame, ascrew, a hand wheel, a valve element, a driving device and a water flow sensor. The high-pressure oblique stop valve provided by the invention has the beneficial effects that in order to solve the problems that a valve fails to be automatically opened and closed and consequentially is difficult to open and close, the driving device is arranged, a motor is energized to make mechanical movement, adriving shaft is driven to rotate, after the speed is reduced through a gear reducer, a connecting rod is driven to rotate on the inner sides of a first bearing and a second bearing through a coupler,accordingly, the connecting rod drives a gear to rotate, the gear drives the screw to move towards the upper end of the fixing frame, and the valve can be automatically opened and closed convenientlyand fast.

Description

technical field [0001] The invention relates to the technical field of cut-off valves, in particular to a high-pressure direct-flow cut-off valve. Background technique [0002] A traditional high-temperature and high-pressure globe valve includes a handle, a worm, a worm nut, a rotating assembly combined with a worm nut lock nut on the upper part of the worm, a valve stem connected to the worm, a valve body, a packing culvert, a valve disc, and a valve seat, among which, Both the inside and outside of the stuffing culvert are equipped with stuffing, and the stuffing outside the stuffing culvert needs to be sealed with the inner wall of the valve body. However, it is difficult to process holes in the valve body, and it is difficult to meet the process requirements. The existing high-voltage direct-flow globe valve cannot automatically The opening and closing of the valve leads to difficulty in opening and closing the valve, and it is impossible to measure the water flow, resu...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the deficiencies of the existing technology, a high-pressure direct-flow stop valve is proposed to solve the problem that the existing technology cannot automatically open and close the valve, resulting in difficulty in opening and closing the valve, and the inability to measure the water flow, resulting in low practicability. , to achieve the ability to automatically open and close the valve, making the door open and close convenient and fast, capable of measuring the water flow, and increasing the beneficial effect of practicality
