Abstract
The utility model relates to a chlorine normal-pressure check valve. The chlorine normal-pressure check valve comprises a chlorine inlet end socket allowing chlorine to enter and a chlorine outlet end socket allowing the chlorine to flow out, wherein the chlorine inlet end socket and the chlorine outlet end socket are clamped through a bolt, a polytetrafluoroethylene middle partition board and a polytetrafluoroethylene piston are installed between the chlorine inlet end socket and the chlorine outlet end socket, a piston hole is formed in the center of the polytetrafluoroethylene middle partition board, an annular chlorine distributing hole is formed in the portion, outside the piston hole, of the polytetrafluoroethylene middle partition board, a chlorine distributing groove is formed in the surface, close to the chlorine outlet end socket, of the polytetrafluoroethylene piston, a piston pin is arranged on the surface, close to the polytetrafluoroethylene middle partition board, of the polytetrafluoroethylene piston, when the polytetrafluoroethylene middle partition board is in contact with the polytetrafluoroethylene piston, the piston pin on the surface of the polytetrafluoroethylene piston can right enter the piston hole in the polytetrafluoroethylene middle partition board, and the chlorine distributing hole is blocked by the surface, provided with the piston pin, of the polytetrafluoroethylene piston. Due to the fact that a piston is low in weight and positioning is accurate, almost no pulse phenomenon occurs during operation, and the amount of the chlorine is quite stable during reaction.
Description
Technical field
The utility model relates to a kind of safety check, relates in particular to a kind of lightweight, accurate positioning of piston, no pulse phenomenon almost in the course of the work, more stable chlorine normal pressure safety check in the course of reaction.
Background technique
Behind the liquid chlorine vaporizing, chlorine enters reactor by pipeline or other containers carry out chlorination or oxidation reaction.Because general course of reaction all is normal pressure, the chlorine of overpressure has little time to participate in reaction and just flows to above the conversion zone.The chlorine safety check that does not also have in the market normal pressure or minute-pressure to open, and all be the valve of taking spring or valve flap structure usually, its material is not also accomplished particular requirement aspect anticorrosion.
The model utility content
The utility model provides a kind of lightweight, accurate positioning of piston, no pulse phenomenon almost in the course of the work, more stable chlorine normal pressure safety check in the course of reaction, its purpose is to solve the perishable and unsettled problem of gas output of the valve of taking in the market spring or valve flap structure.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of chlorine normal pressure safety check, described chlorine normal pressure safety check comprises the end socket of giving vent to anger that air inlet end socket that chlorine enters and chlorine are gone out, described air inlet end socket and giving vent to anger clamps by bolt between the end socket, described air inlet end socket and give vent to anger teflon intermediate clapboard and teflon piston are installed between the end socket, teflon intermediate clapboard center has piston hole, be provided with the chlorine tap hole of annular on the teflon intermediate clapboard outside the piston hole, have the chlorine splitter box on the face of teflon piston near the end socket of giving vent to anger, be provided with wrist pin near on the one side of teflon intermediate clapboard, when the two contacts when teflon intermediate clapboard and teflon piston, the wrist pin that teflon piston is provided with the one side of wrist pin just enters the piston hole of teflon intermediate clapboard, and the one side that teflon piston is provided with wrist pin seals the chlorine tap hole.
In specific embodiment of the utility model, described air inlet end socket and the end socket of giving vent to anger are hemispheric end socket.
In specific embodiment of the utility model, the gap between described wrist pin and the piston hole is at 0.05-0.1mm.
Positive progressive effect of the present utility model is: the utility model when chlorine from vaporizing chamber out, the caliber by DN25 enters the air inlet end socket, the chlorine tap hole by the teflon intermediate clapboard backs down teflon piston.When teflon piston rising certain altitude, the end socket curved surface of being given vent to anger withstands.At this moment follow-up chlorine enters the end socket pipe of giving vent to anger by the chlorine splitter box and enters reaction vessel.According to the safety check of DN25 piping design, the weight of its piston is about 180 grams, so the chlorine after the vaporization slightly has minute-pressure just can back down teflon piston.Processing degree of finish between wrist pin and the piston hole is higher, and gap therebetween is at 0.05-0.1mm, so be shifted up and down, locate all very correct.
When logical chlorine termination, when entering the valve closing of air inlet end socket, teflon piston is because the relation of gravity falls automatically, and its sealing surface all covers the intermediate clapboard tap hole, reaches the effect of non-return.Because the weight of teflon piston is lighter, accurate positioning, almost more stable in the no pulse phenomenon course of reaction in the course of the work.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
Fig. 1 is structural representation of the present utility model, as shown in Figure 1: the utility model comprises the end socket 200 of giving vent to anger that air inlet end socket 100 that chlorine enters and chlorine are gone out, air inlet end socket 100 and giving vent to anger clamps by bolt between the end socket 200, air inlet end socket 100 and give vent to anger teflon middle splint 300 and teflon piston 400 are installed between the end socket 200, teflon intermediate clapboard 300 centers have piston hole 301, be provided with the chlorine tap hole 302 of annular on the teflon intermediate clapboard 300 outside the piston hole 301, have chlorine splitter box 401 on the face of teflon piston 400 near the end socket 200 of giving vent to anger, be provided with wrist pin 402 near on the one side of teflon intermediate clapboard 300, when the two contacts when teflon intermediate clapboard 300 and teflon piston 400, the wrist pin 402 that teflon piston 400 is provided with the one side of wrist pin 402 just enters the piston hole 301 of teflon intermediate clapboard 300, the one side that teflon piston 400 is provided with wrist pin 402 seals chlorine tap hole 302, and air inlet end socket 100 and the end socket 200 of giving vent to anger are hemispheric end socket.
When chlorine from vaporizing chamber out, the caliber by DN25 enters air inlet end socket 100, the chlorine tap hole by teflon intermediate clapboard 300 backs down teflon piston 400.When teflon piston 400 rising certain altitude, end socket 200 curved surfaces of being given vent to anger withstand.At this moment follow-up chlorine enters end socket 200 pipes of giving vent to anger by chlorine splitter box 401 and enters reaction vessel.According to the safety check of DN25 piping design, the weight of its piston is about 180 grams, so the chlorine after the vaporization slightly has minute-pressure just can back down teflon piston 400.Processing degree of finish between wrist pin 402 and the piston hole 301 is higher, and gap therebetween is at 0.05-0.1mm, so be shifted up and down, locate all very correct.
When logical chlorine termination, when entering the valve closing of air inlet end socket 100, teflon piston 400 is because the relation of gravity falls automatically, and the interval hole tap hole all covers in its sealing surface handle, reaches the effect of non-return.Because the weight of teflon piston 400 is lighter, accurate positioning, almost more stable in the no pulse phenomenon course of reaction in the course of the work.
