Abstract

The utility model relates to a communication valve. The communication valve comprises a valve body and a handle, wherein a top flange is arranged on the valve body; the handle is arranged on the top flange of the valve body; the valve also includes a fixing support plate; one end of the fixing support plate is arranged on the top flange; a proximity switch or a travel switch is fixed on the other end of the fixing support plate; and the control point of the proximity switch or the travel switch is in fit control with the handle. According to the technical scheme, a butterfly valve and a ball valve with the proximity switch and the travel switch with signal feedback function can be developed and can be widely used on pressure pipes of various kinds of hydraulic equipment to ensure quick and accurate operation of the equipment. The communication valve not only can determine the accuracy of on-off position, but also can save time and effort, thereby providing reliable security for operation of the various kinds of equipment, improving operation capability of the entire equipment pipe, and realizing large economic benefit of the equipment pipe.

Description

A kind of sender valve

Technical field

The utility model relates to a kind of valve, particularly relates to a kind of sender valve that has signal transmitter.

Background technique

In the prior art, the center line soft sealing butterfly valve, the keying critical component of 1 butterfly valve is to be discoidal butterfly valve; Valve shaft around the center line symmetry in the caulking gum of valve body the inside can rotate by 360 degree, and open-close convenient is rapid, laborsaving saving time; Fluid resistance is very little, and moment of torsion is very light during keying; 2 because butterfly valve only needs 90 ° keying stroke in pipeline uses; Valve plate and valve shaft itself do not have self-lock ability; So location for valve plate; Install spacing fluted disc or worm speed reducer or electro-pneumatic device etc. additional at the valve shaft end, make butterfly plate can be opened to the position at any angle in 90 ° of strokes, it is very flexible to operate; 3 soft sealing butterfly valves are simple in structure, and volume is little, and are in light weight; 4 soft sealing butterfly valves do not have directivity, and installation, maintenance etc. are very convenient.Ball valve is to make open-shut device with the spheroid that has circular channel, and spheroid rotates the valve of realizing switching motion with valve rod.The open-shut device of ball valve is a porose spheroid, winds the axis rotation perpendicular to passage, thereby reaches the purpose that opens and closes passage.Ball valve mainly supplies the usefulness of opening and closing pipeline and equipment medium, and 1 ball valve does not receive the restriction of installation direction, and the flow direction of medium can be any.Fluid resistance is little, and the ball valve in all-pass footpath does not have flow resistance basically; 2 is closely reliable, and it has two sealing surfaces, and the widely-used various plastics of the seal face materials of present ball valve, and good airproof performance can be realized sealing fully.Also widely-used in vacuum system; 3 is easy to maintenance, and ball-valve structure is simple, and seal ring generally all is movable, and dismounting and change is all more convenient; 4 ball valve sealing performances are good.When standard-sized sheet or full cut-off, the sealing surface of spheroid and top flange and media isolated when medium passes through, can not cause the erosion of valve sealing face.

Advantage based on above-mentioned valve; These two kinds of valves occupy very big proportion on pipe applications, this manually operated valve, be installed on the pipeline after; Whether putting in place of valve opening and closing; Had only in the past and observe the indicating positions that drives in front of the valve and just can make a determination, the valve of some specific position also should not judge, so very waste of manpower and time.

In recent years, along with development of science and technology, very big variation has all taken place in the application of pipe-line equipment and management, and integrated, automatic management becomes main flow.

Summary of the invention

In view of this; The main purpose of the utility model is to provide a kind of sender valve; Through the present technique scheme, behind near the increase signal feed back switch Joystick, not only can judge the accuracy of valve opening and closing position; Also practiced thrift time and efforts, for the operation of various device provides more reliable guarantee property.

In order to achieve the above object, the technological scheme of the utility model is achieved in that a kind of sender valve, includes valve body and handle; Above valve body, be provided with top flange; Said handle is arranged on the top flange top of valve body, also includes the fixing branch frame plate, and an end of said fixing branch frame plate is arranged on the top flange; Be set with on the other end of said fixing branch frame plate near switch or position limit switch, control matches with handle at said control point near switch or position limit switch.

Said fixing branch frame plate one end is provided with screwing through hole, and said fixing branch frame plate is fixed on the top flange of valve body through set screw.

Beneficial effect after the employing technique scheme is that a kind of sender valve is through the present technique scheme; Develop the butterfly valve and the ball valve near switch and position limit switch of band signal feedback; Be widely used on the various hydraulic equipment pressure pipings, good guarantee be provided, not only can judge the accuracy of valve opening and closing position for equipment moves fast and accurately; Also practiced thrift time and efforts; For the operation of various device provides more reliable guarantee property, improved the ability of integral device pipeline operation, brought into play the bigger economic benefit of equipment pipe.
