Model utility content
For overcoming above the deficiencies in the prior art, the technical problems to be solved in the utility model is to provide a kind of leakage that effectively can prevent flowing medium under the long term of flowing medium, thus realize reliably, stably fluid medium carry out the novel switched stop valve blocking sealing.
The technical solution of the utility model is: a kind of novel switched stop valve, comprise valve body, valve gap is provided with on the top of valve body, valve rod valve gap being provided with handwheel and being connected with handwheel, water intake and water outlet is respectively equipped with in the left side central portion of valve body and lower right side, columniform valve member is connected with in the bottom of valve rod, outside thread is provided with in the surrounding of valve member, the madial wall of the valve body between water intake and water outlet is provided with internal thread, and carry out screw-thread fit between the outside thread of valve member and the internal thread of valve body, tip cone down is also provided with in the bottom of valve member, bottom in valve body is also provided with block and Returnning spring, block is positioned at the below of valve member and contacts with cone, the left side of block is connected with one end of Returnning spring, the other end of Returnning spring is connected with valve body, and when valve member moves down, cone drives block move to water outlet direction and block water outlet.
Above-mentioned novel switched stop valve, is wherein also provided with Gask-O-Seal on the madial wall of valve body being positioned at water outlet position.
Above-mentioned novel switched stop valve, wherein block is ramp structure with the structure at cone contact position place, and the outer surface of this ramp structure and cone is snug fit.
Above-mentioned novel switched stop valve, wherein the cone angle of cone is 60 ° to 90 °.
Above-mentioned novel switched stop valve, is wherein provided with screw thread valve opening, valve rod is provided with outside thread on valve gap, for being threaded between valve rod and the screw thread valve opening of valve gap.
Above-mentioned novel switched stop valve, is wherein also provided with Gask-O-Seal in the joint of valve rod and valve gap.
The beneficial effects of the utility model are: by adopting said structure, even if the utility model is under the long term of flowing medium, also the leakage of flowing medium can effectively be prevented, thus realize reliably, stably fluid medium carry out blocking sealing, this ensure that structure stability and the usability of switch stop valve greatly.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Fig. 1 is the structural representation of novel switched stop valve.
In figure: valve body 1, valve gap 2, handwheel 3, valve rod 4, water intake 5, water outlet 6, valve member 7, cone 8, block 9, Returnning spring 10.
Embodiment
As shown in Figure 1, a kind of novel switched stop valve, comprise valve body 1, valve gap 2 is provided with on the top of valve body 1, the valve rod 4 valve gap 2 being provided with handwheel 3 and being connected with handwheel 3, water intake 5 and water outlet 6 is respectively equipped with in the left side central portion of valve body 1 and lower right side, columniform valve member 7 is connected with in the bottom of valve rod 4, outside thread is provided with in the surrounding of valve member 7, the madial wall of the valve body 1 between water intake 5 and water outlet 6 is provided with internal thread, and carry out screw-thread fit between the internal thread of the outside thread of valve member 7 and valve body 1, tip cone 8 down is also provided with in the bottom of valve member 7, bottom in valve body 1 is also provided with block 9 and Returnning spring 10, block 9 is positioned at the below of valve member 7 and contacts with cone 8, the left side of block 9 is connected with one end of Returnning spring 10, the other end of Returnning spring 10 is connected with valve body 1, and when valve member 7 moves down, cone 8 drives block 9 move to water outlet 6 direction and block water outlet 6.
When real work, when handwheel 3 and valve rod 4 are in the state of outwarding winding of upwards position, valve member 7 and cone 8 are in the position leaving water intake 5 and water outlet 6, block 9 is also positioned at the left side (namely away from water outlet 6) of valve body 1 under the effect of Returnning spring 10, now flowing medium just can flow into from the water intake 5 of valve body 1, flow out from the water outlet 6 of valve body 1, namely achieve the on state of switch stop valve, when rotation hand wheel 3 and valve rod 4 make it move down, valve member 7 and cone 8 also start to move down thereupon, now start to carry out screw-thread fit between the outside thread of valve member 7 and the internal thread of valve body 1, valve member 7 achieves the first resealing to valve body 1, meanwhile, along with moving down of cone 8, cone 8 contacts and drives block 9 to move to the right side in valve body 1 (namely progressively near water outlet 6), and constantly moving down along with valve member 7 and cone 8, block 9 just finally moves to water outlet 6 place and blocks water outlet 6, the second resealing to valve body 1 is achieved by block 9.Therefore, by said structure, in valve body 1, just achieve the double seal to water intake 5 and water outlet 6, thus greatly ensure that the sealing effect of switch stop valve.
For above-mentioned novel switched stop valve, wherein on valve gap 2, be provided with screw thread valve opening, valve rod 4 is provided with outside thread, for being threaded between valve rod 4 and the screw thread valve opening of valve gap 2, in addition, the madial wall of valve body 1 being positioned at water outlet 6 position is also provided with Gask-O-Seal.In like manner, also Gask-O-Seal can be provided with at valve rod 4 and the joint of valve gap 2.
As preferably, for above-mentioned novel switched stop valve, wherein block 9 is ramp structure with the structure at cone 8 contact position place, and the outer surface of this ramp structure and cone 8 is snug fit, and further, wherein the cone angle of cone 8 is 60 ° to 90 °.
In sum, by adopting said structure, even if the utility model is under the long term of flowing medium, the leakage of flowing medium also effectively can be prevented, thus realize reliably, stably fluid medium carry out blocking sealing, this ensure that structure stability and the usability of switch stop valve greatly.
By reference to the accompanying drawings the preferred embodiment of the utility model and embodiment are explained in detail above, but the utility model is not limited to the above-described embodiment and examples, in the ken that those skilled in the art possess, various change can also be made without departing from the concept of the premise utility.
