Description

A kind of automatic open close compensation flap

Technical field

This utility model relates to a kind of fluid control valve, particularly relates to a kind of automatic open close compensation flap.

Background technology

Valve is in fluid system, be used for controlling the direction of fluid, pressure, the device of flow be make pipe arrangement and equipment in Medium (liquid, gas, powder) flow or stop and controlling the device of its flow.

Valve is control parts in pipeline fluid induction system, is used for changing path section and media flow direction, has Water conservancy diversion, end, throttle, non-return, the function such as shunting or overflow release.The valve controlled for fluid, from simplest stop valve Various valves used in extremely complex robot control system(RCS), its kind and specification are various, and the inside nominal diameter of valve is from atomic little Gauge valve reach greatly the industrial pipeline valve of 10m to latus rectum.Can be used for controlling water, steam, oil product, gas, mud, various corrosion The all kinds such as property medium, liquid metal and radioactive fluid fluidly flow, and the operating pressure of valve can be from The supertension of 0.0013MPa to 1000MPa, operating temperature can be with the high temperature of the ultralow temperature to 1430 DEG C of c-270 DEG C.

Owing to all kinds of more being typically provided with of valve opens and closes handwheel or handle, when pipeline one end goes wrong, it is necessary to use hands Valve closed by wheel or handle, at this moment uses handwheel or handle shut-in time slow, easily causes substantial amounts of water waste, pipeline Easily cause fluctuation, cause the pressure reduction before and after it bigger, cause hydraulic pressure unbalance.

Although owing to common valve can reach circulation or the cut-off of effective control piper medium, but its parts are relatively Many, assembling is wasted time and energy, and labor strength is bigger, and production cost is the highest；Additionally, due to this common valve zero Part is more, complicated structure, and when valve slightly damages, detachable maintaining bothers very much, typically can only integral replacing, waste money Source.

Summary of the invention

For the problem of above-mentioned existence, this utility model provide a kind of simple in construction, assemble simple and convenient, realize before and after press Difference autobalance, it is achieved automatically turn on or close valve function, detachable maintaining readily a kind of automatic open close compensation flap.

For solving this technical problem, this utility model takes below scheme: a kind of automatic open close compensation flap, including valve Body, valve rod, valve gap, described valve body is provided with the water inlet end of horizontal medium circulation and the water side of longitudinal medium circulation, described valve body Top is provided with valve gap, is provided with O RunddichtringO between described valve body and valve gap, it is characterised in that: include movable part, valve body, valve gap, Ball valve and conduit, described valve inner is provided with keying valve rod and movable part, is provided with O type and seals between described movable part and valve body Circle, described valve rod one end is passed movable part, and is pinned by nut, is additionally provided with O RunddichtringO, described valve between itself and movable part The bar other end is additionally provided with sealing ring through valve body, and and valve body between be additionally provided with O RunddichtringO, between described movable part and valve body If unlatching chamber, being provided with closedown chamber between described movable part and valve gap, described valve inleting water end is provided with open hole, and described unlatching chamber is same Sample is provided with the open hole being connected with water inlet end, uses conduit to be connected with tee ball valve, and form loop between two open hole, Described valve body water side is provided with pass closed pore, is provided with pass closed pore outside described valve gap, and communicates with closing chamber, two close closed pore it Between same use conduit to be connected with ball valve, and form loop.

Improve further: between described valve rod and valve seat, use rubber sealing design.

Improve further: with bolts between described valve gap and valve body.

Improve further: described O RunddichtringO is equipped with two.

By using preceding solution, the beneficial effects of the utility model are: described valve inner is provided with keying valve rod With movable part, being provided with O RunddichtringO between described movable part and valve body, described valve rod one end passes movable part, and passes through nut Pinning, be additionally provided with O RunddichtringO between itself and movable part, the described valve rod other end is additionally provided with sealing ring, and and valve through valve body It is additionally provided with O RunddichtringO between body, sets unlatching chamber between described movable part and valve body, between described movable part and valve gap, be provided with pass Close chamber, use two-chamber design, it is possible to ensureing that intake pressure is Jun Heng with discharge pressure, described valve inleting water end is provided with open hole, institute State and open the open hole that chamber is again provided with being connected with water inlet end, between two open hole, use conduit to be connected with tee ball valve, And forming loop, described valve body water side is provided with pass closed pore, is provided with pass closed pore, and communicates with closing chamber outside described valve gap, its Two close same employing conduit between closed pore and are connected with ball valve, and form loop, and its principle is: when pipe water, and water is successively Entering open hole, conduit and ball valve and enter back into unlatching chamber, at this moment valve realizes automatically turning on, and current direction water side turns off stream To the ball valve closing chamber.When front and back's pressure reduction is to be kept in balance, only ball valve need to be opened with tee ball valve simultaneously, at this moment pass through It is complementary that movable part carries out pressure differential, and high pressure is complementary toward low pressure, it is achieved water inlet end keeps consistent with water side pressure reduction, when needs are closed During valve, the tee ball valve opening loop is closed and switch and communicates with air, the loop in cut-out unlatching chamber, at this moment pass through water outlet Hydraulic pressure enters conduit and the ball valve closing loop, chamber, enters back into closedown intracavity portion, and the pressure turning off intracavity quickly raises, band Valve port on valve seat is blocked closedown, a kind of automatic open close compensation flap parts of the present utility model together with valve rod by dynamic movable part Few, assemble simple and convenient, decrease the labor intensity of workman, be greatly reduced production cost simultaneously, obtain more for enterprise Profit;It addition, simple in construction of the present utility model, detachable maintaining is simple and convenient, when a kind of automatic open close compensation flap slightly During damage, it is not necessary to integral replacing, it is convenient to take maintenance apart, this is the most novel brings the most economic effect to user when putting goods on the market Benefit.

Use rubber sealing design between described valve rod and valve seat, improve this novel product sealing property, described valve gap And with bolts between valve body, described O RunddichtringO is equipped with two.
