Abstract
The utility model provides a brake valve. According to the brake valve, the problem that sealing property of a valve body and a brake plate is not good in the prior art is solved. The brake valve comprises a valve body and a brake plate, wherein a left valve channel and a right valve channel are arranged on the valve body. Sealing rings are respectively fixed between the brake plate and the left valve channel, and between the brake plate and the right valve channel. The brake valve is wedged into a valve body cavity which is formed by two annular sealing faces by using of the brake plate which is formed by two annular sealing faces. By using of the contact friction between two faces of the brake plate and the valve body, a certain sealing specific pressure is achieved, sealing function is achieved, and zero leakage is achieved.
Description
Technical field
The utility model relates to the gate valve field, refers to especially a kind of gate valve that can use under the working condition of High Temperature High Pressure.
Background technique
Industrial valves, the open-shut device of gate valve is flashboard, moving direction and the flow direction of flashboard are perpendicular, and flashboard is cutting out, under the opening state, often is being subject to washing away of flowing medium, particularly under the washing away of high temperature fluid medium, cavitation, loss is very fast, and the flashboard face slightly has distortion or corrosion, and valve just can not use, it is not all right to repair the amateur factory of these valves, so cause great waste.So the gate valve that applying unit is wished is: meet flashboard under the situation of closing, 1.1 times of valve worker pressure values, ne-leakage are born respectively in both sides; Under the unlatching situation, valve body should bear the interior pressure of two times of valve worker pressure values, ne-leakage.Valve body and valve plate surface of contact are not yielding, corrosion-resistant.
The model utility content
The utility model proposes a kind of gate valve, solved in the prior art problem of poor sealing performance between the valve body and flashboard.
The technical solution of the utility model is achieved in that and comprises valve body, is provided with left valve channel, right valve channel in the described valve body; Flashboard is between described flashboard and the described left valve channel, all be fixed with seal ring between described flashboard and the described right valve channel.
As one preferred embodiment, described seal ring is the copper seal ring, and described copper seal ring is welded on described flashboard.
As one preferred embodiment, also comprise valve gap, described valve gap is fixed in the upper surface of described valve body; The joint of described valve gap and described valve body is provided with packing ring.
The utility model is compared the beneficial effect that produces with background technique: the flashboard that gate valve utilizes two annular sealing surfaces to consist of, be wedged in the valve cavity of two annular sealing surfaces formation, rely on two face contact frictions of flashboard and valve body, reach certain seal pressure and realize sealing function, can reach zero leakage, can be used for the operating mode of High Temperature High Pressure, sealing effect is reliable, and the sealing pair friction factor is little, wear-resisting, corrosion-resistant.Valve rod and valve are female, the filler external sealed is all adopted in transition joint place, and with transition joint and the female compression of valve, under the pressure medium effect, generation upwards pressure, and pressure medium is larger, and sealing force is larger, and packing ring has been set up in valve body and valve gap joint, more guarantees the zero leakage of whole gate valve medium.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 be the utility model gate valve partly cut open schematic representation.
Among the figure: the 1-valve body; The 2-left valve channel; The 3-right valve channel; The 4-valve plate; 5-copper seal ring; The 6-valve gap; The 7-transition joint; The 8-valve is female; The 9-handwheel; The 10-nut; The 11-valve rod; The 12-packing ring; 13-the first filler; 14-the second filler.
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.
As shown in Figure 1, gate valve comprises valve body 1, flashboard 4, valve gap 6, valve rod 11, handwheel 9, be provided with left valve channel 2, right valve channel 3 in the valve body 1, be provided with the copper seal ring between flashboard 4 and the left valve channel 2, also be provided with copper seal ring 5 between flashboard 4 and the right valve channel 3, copper seal ring 5 is welded on flashboard 4, flashboard 4 has central shaft, central shaft fixing with valve rod 11 on, the central shaft that valve rod 11 drives flashboards 4 moves up and down, in order to the whole gate valve of opening and closing.Valve gap 6 is fixed in the upper surface of valve body 1, and present embodiment valve gap 6 and valve body 1 adopts and be threaded, and the joint of valve gap 6 and valve body 1 is provided with packing ring 12, with leakage proof.Be fixed with transition joint 7 and valve mother 8 between the handwheel 9 at valve gap 6 and valve body 1 top, valve rod 11 is provided with the first filler 13 with the joint of transition joint 7, and compress the first filler 13 with transition joint 7, valve rod 11 is provided with the second filler 14 with valve mother 8 joint, and compress the second filler 14 with valve female 8, the sealing configuration of this internal-pressure self-sealing can guarantee that medium does not leak.Valve rod 11 tops are provided with screw thread, and handwheel 9 is fixed on the valve rod by nut 10.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
