Abstract
The utility model provides a valve with switch and check function, comprising a valve body. One end of the valve body is an entrance, the other end is an exit, and the midst is provided with a valve opening and a kitted valve gear. The valve gear comprises a bracket arranged on the valve opening, and the bracket is provided with a T-shaped valve. The upper end of the T-shaped valve is a valve plate, and the lower end is a cartridge pole. A screw rod is inserted in the cartridge pole, and a compression spring is provided at the upper part of the valve plate and is sheathed on the screw rod. The T-shaped valve can move up and down, and the distance that the T-shaped valve moves up and down can be controlled by the screw rod; when the screw rod revolves downward to a definite extent, the T-shaped valve seals the valve opening which can not move upward and downward unless the screw rod revolves upward. The utility model is provided with simple structure and convenient use.
Description
Technical field: the utility model relates to a kind of valve, relates in particular to a kind of valve with switch, check function.
Background technique: existing safety check only has the function of non-return, must use complex structure, cost height with gate valve.
Summary of the invention: the purpose of this utility model just provides valve a kind of simple in structure, cheap.
The purpose of this utility model can realize by following scheme, comprise valve body, an end of valve body is import, and the other end is outlet, the centre is provided with valve port and matching used valving thereof, described valving comprises the support that is located on the valve port, and support is provided with a T type valve, and described T type valve upper end is a valve block, the lower end is the tube bar, one screw rod is inserted in the bar, and the top of valve block has a pressure spring to be enclosed within on the screw rod, and described T type valve can be upper and lower mobile on support.Screw rod can be used to control the upper and lower mobile distance of T type valve, and when being screwed into to a certain degree under the screw rod, T type valve sealing valve port can not upper and lowerly move, and has only supination on screw rod, could upper and lowerly move.The utility model is simple in structure, cheap, easy to use.
