In addition, in figure 9b, simply schematically illustrate matching somebody with somebody with the type of tamper evidence 920 for the communications ports 912 The part of conjunction, its remaining part may proceed to extend internally, and be connected with other communications ports, and these partly belong to it is known Technology, in order to avoid obscuring the emphasis of the present invention, therefore do not give and show in figure.

Please continue to refer to shown in Figure 10 a- Figure 10 c, in the embodiment as shown in Figure 10 a- Figure 10 c, the head 9222 With the head bore 9228 to be extended internally from the one end of head 9222 away from the bar portion 9224, the head bore 9228 and the receipts Hold hole 9226 to connect, i.e., head bore 9228 forms the through hole through the head 9222 and bar portion 9224 with accepting hole 9226.This Sample, the through hole of the fixture 922 can use as pipeline passway., can be only by one in the embodiment shown in Fig. 9 a and Fig. 9 b The individual fixture 922 shown in Figure 10 a with Fig. 9 b be fixed on as described in the connecting of being not required to be blocked of one in electromagnetic valve 910 In port 914, pipeline 930 is set to pass through the head bore 9228 and accepting hole 9226 of fixture 922,931 sets of another sealing ring In on the pipeline 930 and between fixture 922 and the bottom of communications ports 914, so as to seal the communications ports 914 With the pipeline 930.So it is achieved that the communications ports 914 of the valve 910 and the connection of the pipeline 930.It can be seen that institute Stating fixture 922 both can be as the immobilising device of the pipeline 930, can also be as the immobilising device of type of tamper evidence 920.

In summary, the type of tamper evidence in the present invention includes fixture 922 and stifled core 924, and the fixture 922 includes having The head 9222 of head bore and the bar portion 9224 with accepting hole, wherein, head bore 9228 and accepting hole 9226 form through hole；Institute Stating stifled core 924 includes stifled core bar 9242 and stifled core print 9244, wherein, the stifled core bar 9244 is removably contained in the collecting In hole 9226, the yardstick of the stifled core print 9244 is more than the size of the accepting hole 9226.Due to the stifled core 924 material compared with Soft easy deformation, therefore when fixture 922 and the combination of stifled core 924 as type of tamper evidence in use, the stifled core print 9244 being deformed can The communications ports of sealing-plug connectedness.Further, since the fixture 922 has through-hole structure, therefore the fixture 922 can be single It can be solely used cooperatively as immobilising device with the communications ports, pipeline, so as to realize the connection of communications ports and exterior tubing. So, the type of tamper evidence in the present invention can not only improve the plug for seal performance to the communications ports of valve, can also avoid brokenly The bad communications ports, and its members can use separately as the immobilising device of pipeline, to save cost.In addition, The species of stock item can be reduced, has the function that to save inventory cost and inventory space.

High pressure chemical liquids holding bottle

Because chemical liquids holding bottle of the prior art typically only includes body and the separable plastic bottle of bottle cap, Bottle cap is switched on during use, liquid in bottle is exposed in atmosphere；Its pressure that can be born has very much in storing process Limit, gas leakage easily occurs in the junction of bottle cap and bottleneck, this not only limits increasing for pressure in bottle, and the gas leaked Chemical vapors can be taken out of simultaneously, produce potential safety hazard.Therefore the one side in the present invention, the present invention provide a kind of chemical liquids Holding bottle, it can bear larger internal pressure, be simple to manufacture simultaneously, can make the liquid in the chemical liquids holding bottle in addition Body is used online in the state of air is completely cut off.

It refer to shown in Figure 11 a, the structural representation of its chemical liquids holding bottle 500 for the present invention in one embodiment Figure；It refer to shown in Figure 11 b, the configuration schematic diagram of its chemical liquids holding bottle 500 for the present invention in one embodiment. In the embodiment shown in Figure 11 a and Figure 11 b, the chemical liquids holding bottle 500 includes storage bottle body 510, bottle stopper 520 and bottle Lid 530.Cavity is formed in the storage bottle body 510, it includes the bottleneck 512 of the protrusion connected with the cavity, the bottleneck External screw thread is with outside 512, chemical liquids can be loaded by the bottleneck in the cavity.Bottle stopper 520 is closely filled in bottleneck In 512.Bottle cap 530 includes top cover 532, the bottle cap side wall 534 formed from the extension of the edge of the top cover 532, the bottle cap side There is internal thread the inner side of wall 534, and the bottleneck 512 and bottle cap 530 are screwed together by external screw thread and screw-internal thread fit.Using When, bottle stopper 520 is closely filled in bottleneck 512 first, then turns the bottle cap 530, bottle cap 530 is installed on described On bottleneck 512, so as to seal the bottleneck 512 of chemical liquids holding bottle jointly by bottle stopper 520 and bottle cap 530.In Figure 11 a and figure In embodiment shown in 11b, the lateral surface of the bottle cap side wall 534 forms hexagonal prism, and its medial surface forms hollow cylinder Body, the external diameter of the diameter of the cylinder and the bottleneck 512 are essentially identical so that what bottleneck 51 can just be adapted to is screwed into described In bottle cap 530；The profile of bottle cap 530 is approximately a six-sided nut, can be tightened in bottle cap 530 by instruments such as spanners On the bottleneck 512；The sideline and turning of the storage bottle body 510 are arc.
