Description

Sampling ball valve

Technical field

The utility model relates to a kind of sampling cock, especially relates to a kind of Sampling ball valve.

Background technique

Sampling cock is the valve that is used to obtain pipeline or equipment medium sample, much needing often dielectric sample to be carried out chemico-analytic occasion, how can use special sampling cock.Working principle or performance during according to sampling are different, and sampling cock mainly is divided into three kinds, comprise the sampling cock of duplex open valve, banjo clip plate valve and band insulation jacket.

Existing alkyd resin reaction kettle is employed on the sampling connection of kettle ordinary ball valve is installed, and when sampling, opens ball valve, and sampling cup is gone in the effluent materials flow in the still, closes ball valve after finishing.Because the spool of this ball valve is through-type, throttle down after sampling is accomplished, spool revolves and turn 90 degrees; The passage two ends of spool are in closed state, are full of resin in the passage, and what when sub-sampling is opened valve down, flow out earlier is the resin of before having sealed up for safekeeping in valve core channel; Be the required sample of this sub-sampling then; Can sneak into the resin that existed the last time of sticking on the conduit wall in the valve core channel like this in this sample, the accuracy of this sample is descended, cause the sampled sample analysis result inaccurate.And the resin that it also can cause sticking on the conduit wall progressively can get more and more, and makes the passage more and more narrow that becomes, and when serious even blocking channel, cause and can't take a sample.

Therefore, need provide a kind of can making not have residue in each sampling late gate, with the sampling cock of guaranteeing that sample is reliable and valve can not stop up.

The model utility content

The technical problem that the utility model will solve provides a kind of Sampling ball valve that can be used in the chemical resin reaction kettle; This Sampling ball valve can make does not have residue in the valve after each sampling, and then can guarantee that the reliable and valve of sample can not stop up.

For solving the problems of the technologies described above; The utility model provides a kind of Sampling ball valve, comprises valve body 1, and said valve body 1 is provided with valve gap 25; Be provided with spherical valve core 2 in the said valve body 1; Be provided with valve seat 4 between said valve body 1 and the said spherical valve core 2, the handle 17 that also is provided with axis 15 on the said valve body 1 and is fixedly connected with said axis 15, said spherical valve core 2 is provided with a depressed part 3; Be positioned on the said spherical valve core 2 and with said depressed part 3 vertical tops and locate to be provided with groove, the end of said axis 15 embeds in the said groove.

Preferably, said depressed part 3 accounts for 1/3rd of spherical valve core 2.

Further, the said valve body 1 outer steam insulation chuck 24 that is provided with.

Further, on the said valve body 1 baffle ring 20 is set, is positioned on the plane near handle 17.

Further, on the said handle 17 locking plate 21 is set.

This Sampling ball valve is not when taking a sample, and the depressed part of spherical valve core is towards the valve inlet direction; In when sampling, rotatable handle 180 degree, spherical valve core makes depressed part towards the valve export direction along with handle rotates, and material is come out by bale-out as spoon is the same through the spherical valve core depressed part.Sampling finishes the back with clean rag cleaning depressed part surface, then closes valve gap and gets final product.

Pass to steam during use in the chuck, Resin Flow is increased, thereby resin can not sticked in the import and export that are cemented in valve.

The Sampling ball valve of the utility model can be used for the sampling of various materials, especially is applicable to the materials that viscosity is big, the primary sample amount is few such as resin; Be particularly useful in the alkyd resin reaction kettle.

The Sampling ball valve of the utility model generally adopts SUS304, the manufacturing of SUS316 stainless steel material.

The advantage of the utility model is:

1, the import and export of common valve valve when opening is on state, and the import and export of this Sampling ball valve valve when opening still are in not on-state;

2, the sampling of resin detects and only to need small amount of sample, but guarantees the promptness and the accuracy of sampling again, and the resin that this Sampling ball valve can not stick batch has well guaranteed the promptness and the accuracy of taking a sample;

3, the shell of this Sampling ball valve has increased the steam insulation chuck, has solved for a long time alkyd resin because viscosity is big, is difficult for cleaning, and the easy blocking valve causes the difficult problem that can't take a sample.
