Abstract
The utility model relates to a multipurpose check valve which comprises a valve body, a valve body sleeve, a spring seat, etc. The multipurpose check valve is characterized in that the check valve also comprises a guide seat installed at the inner side of the valve body sleeve, a spring washer installed at the left side of the valve body sleeve and fastening nuts; an O seal ring on the valve seat is tightly clamped with springs and is sheathed on a valve rod, and the springs and the guide sleeve pressed in the spring seat are installed in one end of the valve body of which the upper end is provided with fastening screws. The multipurpose check valve can be installed on pipelines for delivering vapor and liquid, and can be automatically opened and closed so as to prevent the vapor and the liquid from refluxing. When installed, the multipurpose check valve only needs to be communicated with an outer pipeline, and then, the multipurpose check valve can be used.
Description
The utility model relates to a kind of many check valve of use, and it is applicable on conveying vapour, the liquid line, and automatic on-off prevents a kind of plumbing of vapour, liquid return.
Safety check kind in using now is a lot, mainly contain rise-fall type, rotary-open type, spring reset formula etc., its deficiency that mainly exists is that structural design is reasonable inadequately, its sealing effect is not fine, as spring reset formula safety check, sealing pair adopts nut, pad, the structure of flap and clamping General Purpose Rubber plate, the keying of flap is done guiding by four guiding ribs of body cavity, produces vortex phenomenon when its fluid passes through body cavity, cause area of passage little, pressure is thrown and lost greatly, and is bigger towards decreasing to the flap in the valve body, influences working life, when flap is closed, its time seat power is bigger, causes the shearing stress very big to rubber plate, causes rubber plate bending deflection easily or cuts off, four of valve body guiding ribs and flap cylindrical are done guiding in addition, because the flap guide surface is short, the time jam phenomenon is arranged, influence valve working life.
The purpose of this utility model is to be to provide a kind of simple in structure, good sealing effect can be used for carrying on vapour, the liquid line, automatic on-off prevents the check valve of using of vapour, liquid return more.
The utility model mainly is made of valve body 1, valve body cover 4, spring seat 11 etc., it comprises that also being installed in valve body overlaps the guide bracket 5 of 4 inboards and the spring washer 3 and the tightening nut 2 in left side, close circle 7 of O type and spring 9 clamp and are socketed on the valve rod 8 on the valve seat 6, guide pin bushing 10 be pressed on the spring seat 11 and with pack into an end of valve body 1 of spring 9, valve body 1 upper end is provided with fastening screw trip bolt 12.
The utility model has the advantages that simple in structure, easy to use, cost paper, easily manufacturing, good sealing effect can be used for carrying on vapour, the liquid line, automatic on-off prevents a kind of safety check of using of vapour, liquid return more.
Fig. 1 is the structure sectional view of model utility;
Fig. 2 is a part decomposition assembling figure of the present utility model.
Below in conjunction with description of drawings embodiment of the present utility model:
The utility model mainly is made up of valve body 1, valve body cover 4, spring seat 11 etc., it comprises that also being installed in valve body overlaps the guide bracket 5 of 4 inboards and the spring washer 3 and the tightening nut 2 in left side, O RunddichtringO 7 on the valve seat 6 and spring 9 clamp and are socketed on the valve rod 8, guide pin bushing 10 be pressed on the spring seat 11 and with pack into an end of valve body 1 of spring 9, valve body 1 upper end is provided with fastening screw trip bolt 12.Wherein the inner chamber of valve body 1 and outer surface are the waist drum streamline, the outer surface of valve seat 6 is stained with rubber membrane, and valve body 1, spring seat 11 are to be made by cast iron materials, valve seat 6, valve rod 8 are made by steel material, guide bracket 5, guide pin bushing 10 are made by strengthening nylon material, valve body cover 4 is made by copper material, in the time will being used for this safety check on carrying vapour, liquid line, as long as how outer pipeline is connected and can be used with safety check therewith.
