Description

Integrated combination valve

Technical field：

This utility model is related to valve body technical field used in industrial stokehold, particularly to a kind of alternative traditional three The integrated combination valve of valve group.

Background technology：

In industrial stokehold, three traditional valve groups are that one kind is made up of valve body, two stop valves and a balanced valve, It is a kind of needle valve.

Three valve groups use：

Operation sequence when putting into operation：First, open balanced valve, then open two blowoff valves, more slowly open two Individual stop valve, the air in connecting pipe or dirt are excluded, and close two blowoff valves, this is blowdown.Turn off balanced valve, poor Pressure table can put into operation.

Differential pressure gauge zero point on-line testing operation sequence：It is directly connected to transmitter by flange.

Operation sequence when differential pressure transmitter puts into operation：First, open two blowoff valves on differential pressure transmitter, then beat Drive balanced valve, more slowly open two stop valves, the air in connecting pipe or dirt are excluded, close two blowoff valves, then Close balanced valve, transmitter can put into operation.Differential pressure transmitter zero point on-line testing operation sequence：First open balanced valve, close Close two stop valves, you can balance check is carried out to transmitter.

There is following defect in traditional three valve groups：The range of differential pressure gauge is generally 0～6kPa, far below conduit fluid pressure, Itself overload capacity is not strong, and it is easy to damage, operation and maintenance need to be carried out in strict accordance with operating procedure, and equipment otherwise can be caused to damage Go bad or big personal injury.

Content of the invention：

In view of this it is necessary to provide a kind of structure integrated combination valve simple and simple to operate.

A kind of integrated combination valve, including handle, gland, the first valve rod, half ring set, valve gap, valve body, upper valve base, Second valve rod, the 3rd valve rod, lower valve base, blowoff valve, base, straight pin, combined stuffing and rivet pin, half ring set connects the first valve Bar and the second valve rod, cylinder pin connection second valve rod and the 3rd valve rod, upper valve base body designs pore, designs sealing surface, peace It is contained in body cavity, lower valve base body design sealing surface, lower valve base is arranged on body cavity, and be located at below upper valve base, upper valve Seat is installed with lower valve base coaxial cooperation, and base is fitted in body base, and valve gap is threaded connection with valve body, valve gap and upper valve base Coaxial floating connects, and upper valve base and lower valve base are pressed into body cavity by valve gap, have certain amount of floating, can be from centering, in dress Join finish rear stress test qualified after, rivet pin is fitted on valve body, prevents valve gap from rotating, the first valve rod and gland lead to Cross threaded, handle is fixedly mounted on the first valve rod by screw.

Preferably, gland is equipped with dirt-proof boot.

Preferably, valve body is arranged two blowoff valves, blowoff valve includes blowdown valve element and blowdown valve seat.

Preferably, the second valve rod is equipped with locking nut, locking nut is located at valve gap top.

Preferably, combined stuffing is equipped with Packing seat.

Preferably, base is designed with sealing surface, and base is threaded connection with valve body, arranges first between base and valve body Sealing gasket and the second sealing gasket.

Preferably, the lower end of lower valve base is set with the 3rd sealing gasket.

Preferably, setting the 4th sealing gasket and the 5th sealing gasket between the lower surface of valve gap and the inner chamber of valve body.

This utility model provides that a kind of structure is simple, easy to operate integrated combination valve, instead of traditional completely Three valve groups, half ring set connects the first valve rod and the second valve rod, cylinder pin connection second valve rod and the 3rd valve rod, and upper valve base body sets Meter pore, designs sealing surface, and is arranged on the sealing surface sealed reliable that the upper valve base making in valve body is added with the second valve rod, when second When valve stem seal face is away from upper valve base, IN1 and OUT1 of valve body communicates, conversely, when the second valve stem seal face contacts upper valve base, IN1 the and OUT1 cut-off of valve body.Lower valve base body design sealing surface, is arranged on body cavity, with upper valve base coaxial cooperation, is allowed to With the upper sealing surface sealed reliable of the 3rd valve rod processing, when the second valve stem seal face is away from upper valve base, IN1 and OUT1 communicates When, drive the upper sealing surface of the 3rd valve rod processing to seal with lower valve base, IN2 and OUT2 also communicates.Otherwise when the second valve stem seal Face contact upper valve base when, IN1 and OUT1 end, drive the 3rd valve rod processing upper sealing surface away from lower valve base seal, IN2 and OUT2 ends.

So, this utility model instead of three valve groups completely, overcomes the defect of three valve groups, and structure is simple, easy to operate, Avoid the generation of the accident causing because opening the mistake of stop valve order.

The operation principle of integrated combination valve is：

Combination valve and differential pressure gauge, differential pressure transmitter come into operation program：

1. check：Check that can handle turn clockwise, if the handle that can turn clockwise is to tight condition, now at valve rod In extreme lower position, IN1 → OUT1 and IN2 → OUT2 path cut off.

2. blowdown：Open two blowoff valves on integrated combination valve, turn blowdown valve element counterclockwise, then delay counterclockwise Slow rotary handle 1.5～2 circle, UNICOM IN1 → OUT1 and IN2 → OUT2, the air in connecting pipe or dirt are arranged from sewage draining exit Remove, close two blowoff valves.

Note：This operation operates not under the unsafe conditions such as high pressure, high temperature, low temperature, in order to avoid damaging.

3. balance check：Rotate clockwise handle, valve rod moves down, UNICOMContinue to rotate clockwise handss To tight condition, valve rod contacts hard sealing to handle respectively with sealing surface on valve seat and base sealing surface, simultaneously cut-out IN1 → OUT1 and IN2 → OUT2 path, now can carry out the balance check of differential pressure gauge and differential pressure transmitter.

4. run：Check whether two blowdown valve elements are in tight condition clockwise, if not tightening blowdown valve element, inverse time Pin rotary handle to tight condition, IN1 → OUT1 and IN2 → OUT2 path UNICOM,Path cuts off, combination Valve is put into operation with differential pressure gauge or differential pressure transmitter.
