Abstract
The utility model discloses a bivalve wafer check valve which is composed of a valve body, valve clacks, a supporting seat, a pin shaft, and a torsion spring. The valve clacks are fixed inside the valve body. Two symmetric grooves are arranged at the upper end and the lower end of each valve clack. The fixing seat is fixedly arranged in the grooves. The torsion spring is axially sleeved in the middle of the pin shaft. Two ends of the pin shaft are respectively fixed on the supporting seat. A fixing shaft is arranged on a side portion of the torsion spring. By adoption of the bivalve wafer check valve, on one hand, back flow of media can be prevented, and on the other hand, through changing a traditional structure of placing a pin shaft and a fixing shaft through perforation, maintenance cost is reduced, and safety of utilization is improved.
Description
Technical field
The utility model relates to the check valve structure field, is specifically related to a kind of bivalve Wafer Check Valves.
Background technique
Safety check mainly is made up of valve body, flap, valve rod and spring, adopts the effect that the folder linkage structure is realized preventing medium back flow, and in addition, because safety check valve volume is little, in light weight, price is low, and its use in fluid delivery system is more and more general.But in actual use, because all adopting at valve body, traditional check valve design adopt perforation to place the structure of bearing pin and stationary axle, this sealing structure performance is bad, easily make valve outer leak source occur, make valve frequently impaired easily on the one hand, increase maintenance expenses, security incident appears on the other hand easily, especially under working conditions such as poisonous medium, can cause poisonous medium to be revealed, thereby cause environmental pollution.
The model utility content
For solving the problems of the technologies described above, we have proposed a kind of bivalve Wafer Check Valves, by adjusting the safety check internal structure, change the position of bearing pin and stationary axle, prevent medium back flow, reduce maintenance expenses and improve the purpose of Security to reach.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of bivalve Wafer Check Valves, formed by valve body, flap, supporting base, bearing pin and torsion spring, described flap is fixed in valve inner, two ends are provided with the groove of 2 symmetries about the described flap, described supporting base is fixedly arranged in the described groove, described torsion axis is to being sheathed in the middle of the described bearing pin, and the two ends of described bearing pin are individually fixed on the described supporting base, and described torsion spring sidepiece is provided with stationary axle.
Preferably, described supporting base adopts bolt to be connected in the described groove.
Preferably, adopt spacer ring axially to fill between the two ends of described torsion spring and described bearing pin.
By technique scheme, the utility model is by being fixed in described valve inner with described flap, and two ends arrange the groove of 2 symmetries about described flap, and described supporting base is fixedly arranged in the described groove, particularly adopt bolt arrangement fixedly connected; With described torsion axis to being sheathed in the middle of the described bearing pin, the two ends of described bearing pin are individually fixed in described supporting base, at described torsion spring sidepiece stationary axle is set, can prevent medium back flow on the one hand, on the other hand, changed at valve body and adopted perforation to place the conventional construction of bearing pin and stationary axle, reduced maintenance expenses, improved safety in utilization.

Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technological scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
Below in conjunction with embodiment and embodiment the utility model is described in further detail.
Embodiment
As shown in Figure 1, a kind of bivalve Wafer Check Valves, by valve body 1, flap 8, supporting base 5, bearing pin 3 and torsion spring 2 are formed, described flap 8 is fixed in described valve body 1 inside, two ends the groove 4 of 2 symmetries is set at described flap about in the of 8, described supporting base 5 is positioned in the described groove 4, simultaneously that described supporting base 5 is affixed with described groove 4 usefulness bolts 9, described torsion spring 2 axially is sheathed on described bearing pin 3 centres, the two ends of described bearing pin 3 are individually fixed on the supporting base 5, with adopting spacer ring 6 axially to fill between the two ends of described torsion spring 2 and described bearing pin 3, at described torsion spring 2 sidepieces stationary axle 7 is set.
Above-described only is the preferred implementation of a kind of bivalve Wafer Check Valves of the utility model; should be understood that; for the person of ordinary skill of the art; under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
