Abstract
The utility model relates to a coal gas water sealed valve, belonging to the technical field of valves for cutting off and communicating with coal gas, which comprises a water sealing system and a valve main body. The water tank of the water sealing system is connected with a water supply pipe and the bottom part of the valve, a check valve and a one-way valve are arranged in the water sealing system, and a gas exhaust valve is arranged at the upper part of the valve, the multi-turn driving device (or air cylinder) of the valve main body is connected with the top part of a valve rod; the front end of a telescopic link in an opening-closing body is connected with the concave surface of a spherical plate, the back end of the telescopic link is connected with the inclined trough of a chute board, the chute board is connected on the valve rod, and the valve rod controls the spherical plate to move horizontally; the sealed surface of the valve is deviated from contacting in the opening and closing process, and after the valve is closed, the sealed surface is expanded. A guiding axle is embedded in a spiral guiding groove, and controls the spherical plate to swing in the range of 90 degrees when the valve rod moves vertically, and thereby the opening and the closing of the valve are controlled.
Description
Technical field:
The utility model relates to and is used to block, be communicated with the valve that coal gas is used on the industrial gas pipeline.
Background technique:
Be connected the top of the valve body that blocks or be communicated with a kind of gas pipe valve that coal gas uses on the industrial gas pipeline, many device for revolving and driving link to each other with valve rod (being valve shaft) by speed reducer, spherical plate is a valve plate) be connected on the keying body by flexible rod, opening and closing body is connected on the valve rod by spline, opening and closing the body upper end is connected by the roller housing of slip flat key with the valve rod upper end, roller housing top has the friction ring roller housing to embed in the guiding connecting base groove by roller, guide holder has L shaped groove in 90 ° of scopes, its control opens and closes body and swings 90 ° of scopes, the front portion that opens and closes the flexible rod in the body is connected with the spherical plate concave surface, the rear portion is connected with the clinohedral that T type groove is arranged on the valve rod, and its clinohedral is done by valve rod control, following motion.When valve opening, valve rod passes to friction ring to torque force, friction ring passes to roller housing to torsion, roller housing passes to roller to torque force again, and roller drive spherical plate is rapidly rotated in 90 ° of scopes, drives valve and puts in place when stopping, because the spherical plate quality is big, inertia is also big in rotary course, has a reaction force that the spline on the valve rod is out of shape to valve rod when spherical plate stops, and causes valve to damage; If spherical plate or solid of rotation run into when blocking, friction pair is easy to skid, and fault has just appearred in valve; When valve closing, valve rod because guiding groove angle α is little, is easy to take place locking phenomenon in uphill process, valve can't be opened, and when particularly using operated by handwheel, stem movement is discontinuous, and valve is easier to be stuck.
Summary of the invention
The purpose of this utility model is to provide a kind of coal gas water-sealing valve, and it is a kind of valve that the industrial gas pipeline blocked, was communicated with coal gas that is used for, and this valve seal is reliable, stable performance, and stability of rotation, and simple in structure.
The technical solution of the utility model realizes as follows:
The utility model comprises seal water system and valve body, the spherical plate of valve body is connected in by flexible rod and opens and closes on the body, the flexible rod front portion that opens and closes in the body is connected with the concave surface of spherical plate, the flexible rod rear end is connected with the skewed slot body, the skewed slot body is connected with valve rod, skewed slot body control flexible rod moves, and moves thereby controlled spherical plate.Valve rod is connected with guide sleeve by flat key, the axis of guide embeds in the guiding groove, and the axis of guide is connected with bearing with connecting base, and the guiding groove on the guide sleeve is a spirality, its control opens and closes body and steadily swings 90 ° of scopes, and the interior valve rod top of many device for revolving and driving and valve body is connected.The water supply tank of seal water system is connected with the valve body bottom with supply pipe respectively, and valve body top connects a last air inlet and exhaust valve.
Advantage of the present utility model is as follows:
1, guide sleeve outer wall of the present utility model is designed to spiral slot, and it is designed to equidistant difference and rises amount, valve is not steadily had in opening-closing process impact.
2, drive unit of the present utility model is directly passed to valve rod to warping force when pneumatic (be the straight line axial force), in the time of the lifting of control valve rod, also directly drives and opens and closes body and rotate, and avoids using friction ring to drive its transmission efficiency height, reliable operation.
3, the big valve rod of β angle slides up and down flexibly, and opening/shutting valve can not block.

Fig. 2 is the utility model II enlarged view;
Fig. 3 is the utility model left view;
Fig. 4 is the utility model I enlarged view;
Fig. 5 is guide sleeve (10) 1/4 cylindrical guiding groove unfolded drawings.
Embodiment:
Below in conjunction with Fig. 1-5, structure of the present utility model is further described:
The water supply tank 16 of seal water system links to each other with valve body 4 bottoms with supply pipe, safety check 1 is housed successively, inlet valve 2, discharging valve 3 on the water-supply line; Valve body 4 top setting-air inlet and exhaust valve 14, valve rod 9 tops in many device for revolving and driving 13 and the valve body 4 are connected, opening and closing body 6 interior flexible rod 7 front ends is connected with the concave surface of spherical plate 8, the chute board 5 that opens and closes body 6 inside is connected with valve rod 9, flexible rod 7 rear ends are connected on the skewed slot of chute board 5, chute board 5 control flexible rods 7 move left and right, also just having controlled spherical plate 8 moves, during opening/shutting valve, spherical plate sealing surface and valve body sealing surface disengage, and chute board 5 is controlled on it by valve rod 9, following motion opens and closes body 6 by spline and valve rod 9 engagements, valve rod 9 is connected with guide sleeve 10 by flat key, the axis of guide 11 is embedded in the groove of guide sleeve 10, and β is big for the guiding groove angle, and the axis of guide 11 is located with connecting base 12 usefulness needle bearings, guide sleeve 10 cylindricals have spiral slot in 90 ° of scopes, its control opens and closes body 6 and steadily swings 90 ° of scopes.
The working procedure of its valve is as follows during water-stop:
When opening main valve, bleed off sealing water in the main valve earlier, process: inlet valve 2 is closed, and discharging valve 3 is opened, air inlet and exhaust valve 14 is opened, and after water drained, air inlet and exhaust valve 14 was closed, at this moment, with electric device for valve 13 energisings, main valve is opened, and the coal gas of its gas pipe line is communicated with.
When gas pipe line breaks down or overhaul, with electric device for valve 13 energisings, after its main valve is closed, inlet valve 2 is opened, discharging valve 3 cuts out, air inlet and exhaust valve 14 is opened, at this moment, and after the interior fills with water of wait valve body, air inlet and exhaust valve 14 is closed, its gas pipe line is thoroughly blocked by the press water in the valve, and when running into water failure, the water in the water supply tank 16 in time adds in the main valve.
