Abstract
The utility model discloses a connecting bracket used in pneumatic valves, which connects the pneumatic device and the valve. A cylinder (7) and a valve (1) are respectively connected with the two lengthwise ends of the bracket (3) which is pipe shape and encloses a valve handle (2). The advantages of the utility model is that: the fully closed structure can keep the bracket free of dust and acid smoke, the valve handle and seal components can everlastingly withstand the corrosion of acid smoke and dust, which can significantly increases the service life of the pneumatic valve and largely reduces the work load of daily maintenance; an inspecting port is provided which brings convenience for leakage checking and plugging with pressure, and making centralized detection and safe emission of the toxic gas.
Description
Technical field
The utility model relates to pneumatic valve, particularly a kind of support that is connected that connects Pneumatic actuator and valve body in pneumatic valve.
Background technique
The Pneumatic actuator of pneumatic stopping valve adopts the reciprocating piston cylinder more, and its piston rod is connected with the valve rod of valve body, drives the valve rod straight reciprocating motion by piston rod, makes stop valve open, close between two kinds of working staties and change.The reciprocating piston cylinder is installed on the valve body by connecting support, and existing connection support structurally is skeleton, is provided with the stuffing box packing that valve rod is formed sealing in the bottom that connects support.There is the deficiency of following two aspects in this unlimited skeleton connection support, and the one, outside valve rod is exposed to, corrosion-vulnerable and dust erosion will cause the packing seal premature failure, and the medium of external leakage directly pollutes site environment; The 2nd, stuffing box packing is arranged on the bottom that connects support and is unfavorable for that also worst hot case uses.
The model utility content
Technical problem to be solved in the utility model provides a kind of connection support that is used for pneumatic valve, this connection support can make the lasting acid mist of anti-dust of valve stem seal, can adapt to easily the needs that use under the mal-conditions such as firing, have poison gas (liquid) body and worst hot case well.
The technological scheme that its technical problem that solves the utility model adopts is: the utility model is used for the connection support of pneumatic valve, these vertical two ends that connect support are connected with cylinder, valve body respectively, it is characterized in that: described connection support is valve rod is closed in tubulose in it.
After taking abovementioned technology, because the connection support of tubulose is closed in valve rod in it, therefore can connect dust, acid mist outside the support well isolatedly, make acidic fog resistance corrosion enduringly of valve rod and black box and dust erosion, thereby can improve the working life of pneumatic valve effectively, and reduce the line service amount significantly.
As a kind of preferred version of the present utility model, whether to leak or carry out pressure sealing for ease of detecting the valve rod sealing assembly filler, the top of described connection support is provided with to be detected mouthful.
The beneficial effects of the utility model are, full-closed structure can connect dust, acid mist outside the support well isolatedly, make acidic fog resistance corrosion enduringly of valve rod and black box and dust erosion, thereby can improve the working life of pneumatic valve effectively, and reduce the line service amount significantly; Be provided with and detect mouthful, be convenient to detect and whether leak or carry out pressure sealing, and the poisonous gas that leaks can be drawn centralized detecting and safety dumping.
Description of drawings
This specification comprises as next width of cloth accompanying drawing:
Fig. 1 is the structural representation that the utility model is used for the connection support of pneumatic valve;
Component, toponym and pairing mark among the figure: valve body 1, valve rod 2, connection support 3, combination seal filler 4, gland 5, cup-shaped stuffing box 6, cylinder 7, gland 8, Sealing 9, detection mouth 10, seal ring 11, seal ring 12.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
With reference to Fig. 1, the utility model is used for the connection support of pneumatic valve, these vertical two ends that connect support 3 respectively with cylinder 7, valve body 1.Described connection support 3 is valve rod 2 is closed in tubulose in it.Because the connection support 3 of tubulose is closed in valve rod 2 in it, therefore can well dust, acid mist be connected outside the support 3 isolatedly, make acidic fog resistance corrosion enduringly of valve rod 2 and black box and dust erosion, thereby can improve the working life of pneumatic valve effectively, and reduce the line service amount significantly.
Whether leak or carry out pressure sealing for detecting valve rod 2 black box fillers, be provided with reference to the top of Fig. 1, described connection support 3 and detect mouthfuls 10.Detect mouthfuls 10 setting and whether leak or carry out also the poisonous gas that leaks to be drawn centralized detecting and safety dumping the pressure sealing operation except that being convenient to detect.
The top of described connection support 3 is provided with the black box that forms sealing with valve rod 2.A kind of preferred deployment of described black box has been shown among Fig. 1, and promptly described black box comprises the cup-shaped stuffing box 6 of its axis and valve rod 2 deads in line, is filled with the combination seal filler 4 that is compressed by gland 5 in this cup-shaped stuffing box 6.The replacing of being convenient to black box in the cup-shaped stuffing box 6 independently is set.With reference to Fig. 1, longitudinal separation is provided with and is connected support 3 inwalls and forms Sealing 9, the seal ring 11 that seals on the outer wall of described cup-shaped stuffing box 6.In addition, the bottom of described connection support 3 is provided with the seal ring 12 that valve rod 2 is formed sealing.
With reference to Fig. 1, described detection mouth 10 connects a side sidewall that connects support 3, cup-shaped stuffing box 6 and gland 5, detects mouth 10 and be removably connected with plug on the external port position that connects on support 3 outer walls.As a kind of typical structure, vertical two ends of described connection support 3 respectively have flange plate structure, connect support 3 and removably connect with cylinder 7, valve body 1 formation by flange plate structure and bolt assembly.
The above the utility model that just explains through diagrams is used for some principles of the connection support of pneumatic valve, be not to be shown in the connection support that the utility model will be used for pneumatic valve is confined to and in described concrete structure and the Applicable scope, so every the corresponding modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.
