The present application is described in further detail below with reference to figures 1-3.
The embodiment of the application discloses two way seal's sample valve.
Referring to fig. 1-3, a two-way sealed sampling valve comprises a first valve body 1 and a second valve body 2, wherein a quick-assembly joint seat 3 is arranged on one side, away from the first valve body 1, of the second valve body 2, and the second valve body 2 is locked on the first valve body 1 by the quick-assembly joint seat 3. The inboard valve pocket 21 that is formed with of second valve body 2, the both sides of valve pocket 21 are and open the setting, have seted up through-hole 11 on the first valve body 1, through-hole 11 and the valve pocket 21 intercommunication in the second valve body 2 are provided with sample ball 22 in the second valve body 2, have seted up sample groove 221 on the sample ball 22, and sample ball 22 rotates and installs in the second valve body 2. A sealing assembly 4 is arranged between the sampling ball 22 and the second valve body 2, and the sealing assembly 4 seals a gap between the sampling ball 22 and the second valve body 2. When the sampling valve is used, the sampling ball 22 is rotated, when the sampling groove 221 on the sampling ball 22 is communicated with the through hole 11 on the first valve body 1, liquid in the first valve body 1 flows into the valve cavity 21 of the second valve body 2 through the through hole 11, then the liquid flows into the sampling groove 221 of the sampling ball 22, and then the sampling ball 22 is rotated to take out the liquid in the sampling groove 221.
The quick-assembly joint seat 3 is provided with four bolts 31, the four bolts 31 are uniformly arranged on the quick-assembly joint seat 3 at intervals, one ends of the four bolts 31 sequentially penetrate through the quick-assembly joint seat 3, and one ends of the four bolts 31 penetrating through the quick-assembly joint seat 3 are connected with the first valve body 1 in a threaded mode. One end of each of the four bolts 31 far away from the first valve body 1 is provided with a nut 32, the nuts 32 are in threaded connection with the corresponding bolts 31, and one ends of the four nuts 32 are tightly abutted to the quick-assembly connector base 3, so that the stability of the valve seat connected to the valve body connector is improved.
The sealing assembly 4 includes a first valve seat 41 and a second valve seat 42, and the first valve seat 41 and the second valve seat 42 are disposed in the second valve body 2. Sampling ball 22 is rotatably mounted between second valve seat 42 and second valve seat 42.
The sampling ball 22 is overall spherical, a first sealing surface 414 is formed on one side of the first valve seat 41 close to the sampling ball 22, a second sealing surface 424 is formed on one side of the second valve seat 42 close to the sampling ball 22, and the first sealing surface 414 and the second sealing surface 424 are abutted against the surface of the sampling ball 22. When the sampling ball 22 rotates to be communicated with the through hole 11 on the first valve body 1, the liquid in the valve cavity 21 flows into the sampling groove 221 of the sampling ball 22, then the sampling ball 22 rotates to rotate the sampling groove 221 on the sampling ball 22 to the side away from the through hole 11, and therefore the liquid is taken out.
In the use process, the staff discovers that the pressure in the pipeline is large, after the pipeline is used for a long time, liquid in the pipeline still flows out from a gap between the sampling ball 22 and the first valve seat 41 and between the sampling ball and the second valve seat 42 due to the pressure, after the improvement of a designer, one side, deviating from the second valve body 2, of the quick connector seat 3 is provided with a sampling bottle joint 5, a clamp 51 is arranged between the sampling bottle joint 5 and the quick connector seat 3, the clamp 51 connects the sampling bottle joint 5 to the quick connector seat 3, one side, deviating from the quick connector seat 3, of the sampling bottle joint 5 is provided with a sampling bottle body 52, the sampling bottle body 52 is in threaded connection with the sampling bottle joint 5, a sampling cavity 53 is formed in the sampling bottle body 52, and during the use, the liquid in the sampling groove 221 flows into the sampling cavity 53 in the sampling bottle body 52.
Connect sampling bottle body 52 on sampling bottle connects 5, can be so that sampling ball 22 is at the in-process that uses, and the pressure of both sides is the same, can promote the life of sampling ball 22 on the one hand, and on the other hand can promote the leakproofness between sampling ball 22 and first disk seat 41, the second valve seat 42, and the non-pressure sample can be accomplished to tender when the sample simultaneously for convenience when the staff samples can promote.
The implementation principle of the sampling valve with the two-way sealing function in the embodiment of the application is as follows: in the application, liquid flows through the first valve body 1, and is left in the valve cavity 21 of the second valve body 2 through the through hole 11 on the first valve body 1, then the sampling ball 22 is rotated, after the sampling groove 221 on the sampling ball 22 is communicated with the through hole 11, the liquid in the valve cavity 21 flows into the sampling groove 221, then the sampling ball 22 is rotated, when the sampling groove 221 on the sampling ball 22 is rotated to the side deviating from the through hole 11, the liquid in the sampling groove 221 flows into the sampling bottle body 52, in the rotating process of the sampling ball 22, the first groove 411, the first boss 412 and the first inner circle 413 abut against the quick-assembly connector seat 3, the second groove 421, the second boss 422 and the second inner circle 423 abut against the first valve body 1, and the first sealing surface 414 and the second sealing surface 424 on the first valve seat 41 and the second valve seat 42 respectively abut against the surface of the sampling ball 22.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
