Abstract
The utility model relates to a valve which is characterized by having a valve and a valve head used to seal the valve; one end of the valve head is arranged in a solution release cavity of the valve; a valve stem connected with the valve head extends outwards from the inside of the valve; the solution release cavity is communicated with a solution outlet and a blow-down port; the valve stem is a screw rod; the valve stem and the valve are connected by thread; the outer wall between a sealing port of the valve and a solution outlet or the blow-down port is provided with a flange; an installation hole is opened on the flange; the valve head is a flat gasket type flexible sealing valve head of a conical flexible sealing valve head. The valve has the advantages that a valve head sealing valve seat section is arranged in a container or in a pipe with solution continuously flowing, which effectively prevents crystallized caecum pipe sections; the steam blow-down port opened on the valve can timely clean the residual solution in the valve cavity every time after use, so as to prevent crystallization of the fused solution after being cooled down, so that the users can open and immediately use in operation, such as guide spraying, sampling, etc., and the crystallized pipe sections do not need to be blown down with steam for a long time.
Description
Technical field
The utility model relates to be used for as melt and dissolved state, the sampling cock of easy crystalline material or the valve of showering guilding valve.
Background technique
Evaporating, concentrating is one of requisite unit operation in the industries such as chemical industry, light industry.In this process, can produce the material of melt and dissolved state inevitably.These materials are very easily emitted heat in storage process, and generate crystallization.
At present, aborning common valves such as stop valves, gate valve, ball valve that use are as sampling cock and showering guilding valve more, and its installation method is in the sampling of container and pipeline or leads the pipe nipple that drenches the flanged or thread of one of outlet welding, connects this class common valve again.Because between valve and the valve or valve and sampling, lead to drench between the outlet(discharge) flange certain distance is arranged, this segment pipe is easily stopped up by crystallization when melt and dissolved state solution is not mobile fully.Therefore must blow down crystallization in this segment pipe for a long time with steam in sampling and before discharging this type of solution, long even reach the time, cause in time taking a sample and to remove the residual solution in the pipe, make to produce to be absorbed in passively, make troubles to operation.
Summary of the invention
The purpose of this utility model just provides a kind of can the pouring and plug and play during sampling leading, needn't be for a long time with the valve of steam blowing pipeline intercrystalline section.
Solution of the present utility model is such: the valve head that includes valve body and be used for sealed valve body, an end of described valve head are that the solution that is positioned at described valve body discharges the chamber, and the valve rod that is connected with valve head is protruding in the valve body; In solution discharges the chamber, be communicated with taphole and blow down mouth.
In such scheme, described valve rod can be a screw rod, and valve rod adopts with valve body and is threaded; The sealed mouth of described valve body and taphole or the outer wall that blows down between the mouth can be provided with flange, can have mounting hole on flange; Described valve head can be a plain cushion type soft seal valve head, also can be tapered soft seal valve head.
The utility model has the advantages that: 1, be provided with flange at the sealed mouth of valve body and the outer wall between taphole or the blowing mouth, can be during installation one section pipe interior that is installed in internal tank or solution continuous-flow is arranged of valve head sealed valve body, effectively avoided the appearance of crystallization caecum pipeline section, and the steam of offering on valve body blows down mouth, can be at each solution that uses remnants in the timely scavenging valve body cavity in back, avoid melt and dissolved attitude solution cooling post crystallization, make the user lead pouring, can plug and play when sampling waits operation, needn't blow down the crystallization pipeline section for a long time with steam again.2, valve head adopts plain cushion type or tapered soft sealing structure, good seal performance, and not easy to wear causing reveals.
Description of drawings
Accompanying drawing is embodiment of the present utility model.
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is user mode structural representations of the present utility model.
Embodiment
Present embodiment includes valve seat 1, valve head 2, valve body 3, flange 4, blows down mouth 5, valve rod 6, taphole 7.
One end of described valve head 2 is that the solution that is positioned at described valve body 1 discharges chamber 3, and the valve rod 6 that is connected with valve head 2 is interior protruding from valve body 1; In solution discharges chamber 3, be communicated with taphole 7 and blow down mouth 5.
Described valve rod 6 is screw rods, and valve rod 6 adopts with valve body 1 and is threaded.
The sealed mouth of described valve body 1 and taphole 7 or the outer wall that blows down between the mouth 5 have flange 4, have mounting hole on flange 4.
Described valve head 2 is plain cushion type soft seal valve head or tapered soft seal valve head.
In Fig. 1, embodiment shown in Figure 2, the valve head 2 of sealed valve body 1 is the valve head of tapered sealing, and the solution that the one end is positioned at valve body 1 discharges chamber 3, is connected with the valve rod 6 that stretches out outside the valve body 1 on valve head 2, this valve rod 6 is screw rods, it with valve body 1 between adopt and be threaded.Be provided with one in a side of valve body 1 and be communicated with the blowing mouth 5 that solution discharges chamber 3, be provided with a taphole 7 that discharges chamber 3 equally together with solution at the opposite side of valve body 3.At the sealed mouth of valve body 1 and the outer wall between taphole 7 and the blowing mouth 5 flange 4 is housed, on flange 4, have mounting hole, when mounted, the position of flange 4 can make one section pipe interior that is installed in internal tank or solution continuous-flow is arranged of valve head 2 sealed valve bodies 1, effectively avoids the appearance of crystallization caecum pipeline section.
When using as sampling cock, open valve rod 6, remove the sealing of 2 pairs of valve bodies 1 of valve head, solution enters into solution from valve body 1 and discharges in the chamber 3, is flowed out by the taphole of opening 7.After finishing using, close valve rod 6 and open steam, steam is discharged in the chamber 3 by blowing down mouthful 5 solution that enter valve body 1, solution is discharged chamber 3 interior residual solutions blow down clean by taphole 7.When using as blow through valve, must increase a valve at taphole 7 places, during blowing, open valve rod 6 and close the valve that connects taphole 7 simultaneously, open steam, steam is discharged in the chamber 3 by blowing down mouthful 5 solution that enter valve body 1, blow back the sealed mouth of solution by valve body 1 in the container or in the pipeline, blow down to close after a period of time and connect the steam valve that blows down mouth 5 and get final product.
