Abstract
The utility model discloses a kind of vacuum hand-operated valve, including valve body, valve element and operation handle, the valve body uses three-port structure, the valve body port includes import, outlet and fluid stopping mouthful, the import and fluid stopping mouthful of valve body port are arranged at two symmetrical parallel ports, the vertical port of the valve body is set to outlet, the valve element front end is placed into for stopping up import from fluid stopping mouth, the valve element rear end is connected with operation handle, the operation handle is installed on the port of the fluid stopping mouthful of the valve body, and it is beneficial in that：Function of the manual vacuum valve to drive the flexible fluid stopping to realize valve element of bellows by torquing operations handle mode and release, the use of metal bellows mitigates dynamics during manual torquing operations handle, while multiple annulus Cao and sealing ring ensure that the sealing of valve.
Description
Technical field
The utility model is related to technical field of vacuum equipment, more particularly to a kind of structural reliability is high, low manufacture cost,
Practicality and safe vacuum hand-operated valve.
Background technology
The utilization of vacuum equipment is more and more extensive, obtains the extensive welcome of people, but still exists more imperfect
Place, such as vacuum hand-operated valve of the prior art, there is poor sealing in it, and have fluid circulation again often because fluid
Hand switch valve is more painstaking caused by pressure.
Utility model content
The purpose of this utility model be in order to solve the defects such as poor sealing in the prior art and manual switch valve be hard,
There is provided a kind of structural reliability high, low manufacture cost, practicality and safe vacuum hand-operated valve solve the above problems.
To achieve these goals, the technical solution of the utility model is as follows：A kind of vacuum hand-operated valve, it is characterised in that bag
Valve body, valve element and operation handle are included, the valve body uses three-port structure, and the valve body port includes import, outlet and fluid stopping mouthful,
The import and fluid stopping mouthful of valve body port are arranged at two symmetrical parallel ports, and the vertical port of the valve body is set to out
Mouthful, the valve element front end is placed into for stopping up import from fluid stopping mouth, and the valve element rear end is connected with operation handle, the behaviour
The port of the fluid stopping mouthful of the valve body is installed on as handle.
Further, the structure leading portion of the valve element is set to cylindrical structure, and the valve element external diameter is less than in the valve body
Footpath 0.5-1.0mm, the valve core structure stage casing is set to metal bellows, and the metal bellows connects with the operation handle
Connect.
Further, multiple parallel annular grooves are set on the cylindrical structure that the structure leading portion of the valve element is set,
Sealing ring is cased with the annular groove.
Compared with prior art, it is beneficial in that the utility model：The manual vacuum valve is to pass through torquing operations hand
Handle mode drives the flexible with the fluid stopping for realizing valve element and the function of releasing of bellows, and the use of metal bellows mitigates revolves manually
Dynamics during operation handle is twisted, while multiple annulus Cao and sealing ring ensure that the sealing of valve.
Brief description of the drawings
Fig. 1 is a kind of structural representation of vacuum hand-operated valve of the present utility model.
Embodiment
To make to have a better understanding and awareness to architectural feature of the present utility model and the effect reached, to compared with
Good embodiment and accompanying drawing coordinate detailed description, are described as follows：
As shown in figure 1, a kind of vacuum hand-operated valve that the present embodiment is provided, including valve body 1, valve element 2 and operation handle 3, institute
State valve body 1 and use three-port structure, the port of valve body 1 includes import 4, outlet 5 and fluid stopping mouthful 6, the port of valve body 1 it is described
Import 4 and fluid stopping mouthful 5 are set to two symmetrical parallel ports, and the vertical port of the valve body 1 is set to outlet 5, the valve
The front end of core 2 is placed into for stopping up the import 4 from the fluid stopping mouthful 6, and the rear end of valve element 2 is connected with operation handle 3, institute
State the port that operation handle 3 is installed on the fluid stopping mouthful 6 of the valve body 1.
Further, the structure leading portion of the valve element is set to cylindrical structure, and the valve element external diameter is less than in the valve body
Footpath 0.5-1.0mm, the structure stage casing of the valve element is set to metal bellows, and the metal bellows connects with the operation handle
Connect.In the present embodiment, the structure of valve element is the most key, is particularly provided with metal bellows, and the inner structure for valve element is moved
Dynamic, the use of metal bellows structure alleviates the dynamics of manual torquing operations handle, the efficiency of the manually operated valve of raising.
Further, multiple parallel annular grooves are set on the cylindrical structure that the structure leading portion of the valve element is set,
Sealing ring is cased with the annular groove.
General principle of the present utility model, principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply principle of the present utility model, the utility model also has respectively on the premise of the utility model spirit and scope are not departed from
Changes and improvements are planted, these changes and improvements are both fallen within the range of claimed the utility model.The utility model requirement
Protection domain defined by appended claims and its equivalent.
