Abstract
The utility model discloses a press cover type flange butterfly valve, comprising a valve body, a valve base, a valve stem and a sealing ring; the valve base is enchased in the chamber of the valve body; a butterfly plate is arranged in the valve base; the inlet and outlet of the valve body are respectively embed in the press cover; the inner end surfaces of the press cover are closely contacted with the end surfaces of both sides of the valve base; the external end surfaces of the press cover are fixedly connected with the pipe flange dish and are sealed; top and bottom connected bores are arranged on the valve body, the valve base and the butterfly plate; the valve stem passes through the bores and fixedly connected with the butterfly plate. The utility model is provided with small volume, light weight, low cost, good sealability, short-time start and stop, high efficiency and strong commonality.
Description
Technical field
The utility model relates to a kind of valve, specifically is meant a kind of gland type flange butterfly.
Background technique
Valve is parts the most frequently used in the mechanical industry, in the giving of water supply industry, drainage pipe, and at present valve such as gate valves that use more, and in use there are some defectives in gate valve, as, valve rod, nut and seal ring in the gate valve body all adopt the brass manufacturing, and cost is higher; Valve body structure is not suitable for the high leak tightness requirement; Flashboard slot is arranged at the body cavity bottom, and easy deposit dirt in this groove makes flashboard be difficult for being inserted into bottom land when using for a long time, influences sealing effect, so need often clear up the sediments in the flashboard slot; In addition, the gate valve opening and closing time is long, and the mounting point does not allow to be inverted, and has shortcomings such as volume is big, heavy, maintenance inconvenience.
The model utility content
The purpose of this utility model is to solve problems such as the volume that existing valve exists is big, sealing is relatively poor, cost is high, opening and closing time is long, provides that a kind of volume is little, good seal performance, gland type flange butterfly that cost is low.
The purpose of this utility model is achieved through the following technical solutions: a kind of gland type flange butterfly provided by the utility model, to form by valve body, valve seat, valve rod, seal ring, and body cavity is inlaid with valve seat, installs butterfly plate in the valve seat; The entry end of valve body and outlet end are respectively charged into a gland, and the exterior edge face of gland is provided with boss, and the screw thread jackscrew is fixed gland and valve body; The interior edge face of two glands closely contacts with the both sides end face of valve seat respectively, fixedlys connected with the piping flange dish by flange gasket and seal in the exterior edge face; Be respectively equipped with the hole that is communicated with up and down on valve body, valve seat and butterfly plate, valve rod passes from the hole and fixedlys connected with butterfly plate.
Gland type flange butterfly of the present utility model is common " A " improve on the basis of type wafer type butterfly valve and form, installed the valve seat of making by rubber or polytetrafluoroethylmaterial material in the valve body, the end of coming in and going out has installed gland additional, one end of gland closely contacts with rubber valve seat, the other end and the sealing of piping flange dish.Compare with traditional gate valve, the utlity model has following advantage with bore:
1. volume is little, in light weight, can save a large amount of metallic material;
2. flow resistance coefficient is little, and good airproof performance can reach zero leakage;
3. opening and closing time is short, the efficient height;
4. highly versatile can directly be changed the various valves of various pipelines, can arbitrarily install in 360 degree scopes, can use various media in the pipeline.
Description of drawings
Fig. 1 is the structural representation of the utility model gland type flange butterfly.
Fig. 2 is the structural representation of valve body in the utility model.
Fig. 3 is the structural representation of gland in the utility model.
Embodiment
Fig. 1 is an embodiment of the utility model gland type flange butterfly.Inner chamber at valve body 1 is inlaid with valve seat, and this valve seat is to be formed by backrest valve seat 2 and rubber valve seat 4 pressings, and wherein rubber valve seat 4 is in the inboard of backrest valve seat 2, the butterfly plate 5 of packing in the valve seat, and butterfly plate cooperates with valve seat after polishing treatment, the precision height; The entry end of valve body and outlet end are respectively charged into a gland 3, and the exterior edge face of gland is provided with the boss (see figure 3), and screw thread jackscrew 11 is fixing with valve body 1 with gland 3; The interior edge face of two glands closely contacts with the both sides end face of rubber valve seat 4 respectively, and the boss of exterior edge face is fixedlyed connected with the piping flange dish by flange gasket and sealed; Be respectively equipped with the hole 13 that is communicated with up and down on valve body 1, backrest valve seat 2, rubber valve seat 4 and butterfly plate 5, valve rod 12 passes from the hole and fixedlys connected with butterfly plate 5.Valve rod 12 is fixedlyed connected valve rod 12 by one or two tapering pin 6 in the present embodiment with butterfly plate 5.
The upper end of valve body 1 is a flange 8, is used to install the start-stop device that the may command valve rod rotates.The end that valve rod 12 stretches out valve body 1 is provided with the connecting key 7 that is connected with start-stop device, by connecting key 7 valve rod 12 is connected with the start-stop device that the may command valve rod rotates, this start-stop device can be handle type manual operating device, worm and gear manual operating device, Pneumatic actuator or Electric actuator.Start-stop device drives valve rod 12 by connecting key 7 and rotates, and 5 swings of control butterfly plate are opened or throttle down.
Between valve body 1 and valve rod 12, axle sleeve 10 is housed.For preventing to leak, between backrest valve seat and the axle sleeve, between axle sleeve and the axle sleeve seal ring 9 is housed all,
The material of gland 3 is identical with valve body material in the utility model, should guarantee in the processing that the length of gland is consistent to the length of valve outlet end face with the valve seat end face.
Claims (5)
