Abstract
The utility model discloses ball valve which belongs to the technical field of valves. The utility model comprises a valve body, a ball-shaped valve core, a valve rod, a sealing ring and a handle, wherein the valve rod, the sealing ring and the handle are connected with the ball-shaped valve core; one side of the valve body is provided with a conical hole communicated with a passage thereof, and a conical valve seat which is matched with the inside of the conical hole in a sealing way is arranged inside the conical hole; the ball-shaped valve core is arranged inside the conical valve seat, a hole communicating the ball-shaped valve core with the passage inside the valve body is arranged inside the conical valve seat. The ball valve is used in a fluid conveying pipeline; compared with the existing ball valve, in the utility model, the ball-shaped valve core and a sealing member can be conveniently adjusted and replaced from the side surface of the valve body.
Description
Technical field
The utility model relates to valve technology field, especially a kind of valve that includes spherical valve core.
Background technique
In system of flow ducts, gate valve, stop valve, these three kinds of valve applications of ball valve get at most, their pluses and minuses are also each has something to recommend him, gate valve, stop valve are owing to not fragile, seepage are used widely, but shortcoming is to open when closed slowly, and stop valve is compared traffic volume with gate valve, the ball valve of identical bore and had only they half.And that ball valve has the amount of opening is big, open and close fast advantage, but its spherical valve core of existing ball valve all is to be located at regularly in the valve body, can only rotate, and need more change the shuttle core or Sealing have only from the dismounting of valve body import or export, and the general also suitable difficulty of dismounting.The ball valve of this structure in use tends to because matching gap increases or Sealing damages and leaks, generally speaking, the ball valve that leaks or damage all is that whole changing abandons, and the service conduit system not only wastes like this, and also quite difficult under many circumstances.Be embedded in ball valve underground or within the walls such as some, it is just very difficult integral body to pull down.The ball valve that is connected with the pipeline of metal composite with plastics PR-R pipeline, plastics and for example, connection between them is to adopt the mode of sweat soldering to be connected, this ball valve must the severing pipeline when changing, replace welding again with new ball valve again, this maintenance work use on-the-spot, especially be extremely difficult at use execute-in-place underground or within the walls, also can cause bigger damage to the scene, maintenance work cost height.
Summary of the invention
The purpose of this utility model is to provide a kind of ball valve, and it can be adjusted or change spherical valve core and Sealing from side of valve body easily.
To achieve these goals, the scheme that the utility model adopts is: it includes valve body, spherical valve core and the valve rod that is connected with this spherical valve core, seal ring and handle, one side of described valve body has a taper hole that connects with its passage, the conical valve seat that cooperates with this taper hole inner seal is housed in it, described spherical valve core is housed in this conical valve seat, is provided with the hole that is communicated with described spherical valve core and described valve inner passage in the described conical valve seat.
The taper hole of above-mentioned valve body generally is provided with enclosing cover outward, can be on the described conical valve seat by the clamping sleeve that is contained in outside the described valve rod that is threaded, and the part that an end of this clamping sleeve stretches out described enclosing cover then is equipped with the adjusting lock nut.Above-mentioned enclosing cover also can be provided with its outside and be polygonal flange around its outside, described valve rod, then be set with its underpart endoporus and described flange in the outside of this flange and be the equipped stop cover of polygonal outer side surface, this stop cover top then offers the through hole equipped with the polygonal outer side surface in described clamping sleeve top.
Owing to adopted such scheme, the utility model for the beneficial effect that prior art has is:
1, maintenance easily, conveniently.No matter valve rod, seal ring, conical valve seat still are that spherical valve core need be adjusted or change, and do not need valve body is pulled down, and just the enclosing cover dismounting just can be realized easily.
2, maybe can not pull down the occasion of valve body in inconvenience, as be contained in valve body underground or within the walls, the time not only save time, and can reduce damage to greatest extent, reduce maintenance cost ground or metope in maintenance.

Embodiment
Below in conjunction with the accompanying drawing example structure of the present utility model is described in further detail:
Among the embodiment illustrated in figures 1 and 2, end face one side of valve body 1 of the present utility model has a taper hole that connects with its passage, the conical valve seat 15 that cooperates with this taper hole inner seal is housed in this taper hole, spherical valve core 16 is housed in the conical valve seat 15, be provided with the hole that is communicated with spherical valve core 16 and valve body 1 inner passage in the conical valve seat 15, the end face of spherical valve core 16 is fitted with valve rod 6, handle 5 is equipped with by nut 7 in the top of valve rod 6, handle with sleeve 5, spherical valve core 16 rotates, and hole in the import of valve body 1 passage and outlet and the conical valve seat 15 and spherical valve core 16 interior through holes are communicated with or seal.Two seal rings 17 are being housed between the stuffing box gland 14 cast in block on valve rod 6 and the conical valve seat 15, seal closure 11 is equipped with on the top of stuffing box gland 14, between the top of seal closure 11 and stuffing box gland 14 sealing gasket 12 is housed, this part structure can guarantee the tightness of the valve rod hole of the outer side surface of spherical valve core 16 and conical valve seat 15.The taper hole of valve body 1 is outer to be equipped with enclosing cover 3 by screw 2, the top of conical valve seat 15 is provided with inner screw sheath 13 cast in block, conical valve seat 15 is connected with the clamping sleeve 10 that an end stretches out enclosing cover 3 by inner screw sheath 13, and the part that clamping sleeve 10 stretches out enclosing cover 3 is equipped with adjusting lock nut 8,9 outward.Loosen nut 8 is taken away stop cover 4, rotates clamping sleeve 10, and clamping sleeve 10 can be pressed on conical valve seat 15 in the taper hole of valve body 1 by its outside screw, to guarantee the tightness of the two.It is equipped that stop cover 4 its underpart endoporus and flange are polygonal outer side surface, this flange is located at enclosing cover 3 on the outside around the valve rod 6, stop cover 4 tops then offer the through hole equipped with the polygonal outer side surface in clamping sleeve 10 tops, this part structure can prevent that clamping sleeve 10 from causing the leakage between valve body 1 and the conical valve seat 15 with respect to enclosing cover 3 rotations when lock nut 8 screws.Stop cover 4 is provided with bump, and it plays position-limiting action to the rotation of handle 5.
