fig. 2 is a schematic diagram two of the working state of the stop valve.
The following reference numerals are marked thereon in conjunction with the accompanying drawings:
1. a valve body; 11. a valve housing; 12. a valve stem; 13. a valve flap; 14. a first closure member; 15. a second closure member; 2. a valve seat; 21. a flow channel.
Detailed Description
In the following, an embodiment of the present invention will be described in detail with reference to the drawings, but it should be understood that the scope of the present invention is not limited by the embodiment.
The stop valve of the water separator of the utility model is shown in fig. 1 and fig. 2, and comprises a valve body 1 and a valve seat 2 matched with the valve body 1, wherein the valve body 1 and the valve seat 2 are respectively arranged on the opposite pipe walls of the water separator; wherein, valve seat 2 has through-going flow channel 21, and valve body 1 includes valve casing 11, and can the slidable valve rod 12 of installing in valve body 1, and this valve rod 12 is provided with valve clack 13 on placing in the terminal of valve casing 11 outside correspondingly, and like this valve rod 12 is in the motion in-process, valve clack 13 can move with the opening of closing valve seat 2's flow channel 21 or deviate from valve seat 2 and move with the opening of opening valve seat 2's flow channel towards valve seat 2, so can realize closing or opening of the corresponding circulation route of water knockout drum.
Specifically, the valve casing 11 is provided with first closed part 14 towards the periphery of the corresponding valve rod 12 of the terminal surface of valve seat 2, fixed cup joint on the valve rod 12 with first closed part 14 matched with second closed part 15, this second closed part 15 links to each other with the cooperation of first closed part 14 with valve rod 12 and outside isolation in it all the time along with valve rod 12 motion in-process, avoids the medium in the water knockout drum directly to erode valve rod 12, thereby the possibility of valve rod 12 scale deposit has been reduced, can guarantee the long-term stable work of stop valve.
In the above solution, specifically, the first sealing element 14 is an annular sealing bracket disposed along the periphery of the valve stem 12, the second sealing bracket is a sealing sleeve fixedly sleeved on the valve stem 12 and located in the sealing bracket, preferably, the sealing bracket is made of a metal material, and the sealing sleeve is made of a reinforced nylon material, so that during the movement of the valve stem 12, the sealing bracket and the sealing sleeve cooperate to form a relatively closed cavity to isolate the valve stem 12 from external media, thereby preventing the media from directly washing the valve stem 12, thus reducing the possibility of scaling of the valve stem 12, and ensuring the long-term stable operation of the stop valve; similarly, the first closing element 14 may also be a ring-shaped structure circumferentially disposed on the outer periphery of the valve stem 12, the second closing element 15 may also be a cap structure fixedly connected to the valve stem 12 and sleeved outside the first closing element 14, and the first closing element 14 and the second closing element 15 may be selectively arranged according to specific needs to ensure that the first closing element 14 and the second closing element 15 always isolate the valve stem 12 from the outside during the movement of the valve stem 12.
Compared with the prior art, the utility model has the advantages of simple and reasonable structure, can realize valve rod and outside isolation through the cooperation of first closure and second closure, effectively avoid the medium in the water knockout drum directly to erode, when the stop valve is in the closure state, the valve rod is in the water cavity of relative stillness simultaneously to reduce the possibility of valve rod scale deposit, can ensure the long-term stable work of stop valve.
The above disclosure is only for the embodiment of the present invention, however, the present invention is not limited thereto, and any changes that can be considered by those skilled in the art should fall within the protection scope of the present invention.
