Description
Technical field
The present invention relates to valve machinery field, especially a kind of novel anti-misoperation formula plunger valve.
Background technique
Plunger valve is made of parts such as valve body, valve deck, valve rod, plunger, aperture frame, sealing ring, handwheels.When handwheel rotate,
Plunger is driven to pump among aperture frame by valve rod to complete the open and close function of valve.The plunger in valve
With sealing interannular using being interference fitted, by adjusting flange bolt in gland, make lateral force and valve caused by sealing ring compression
Hole face and the sealing of plunger outer circle have prevented internal and outernal leakage, simultaneously valve opening torque to ensure that the leakproofness of valve in body
It is small, it is able to achieve valve and opens and closes rapidly.Plunger valve compares shut-off valve, and the service life is long, rapid operation.But adjust stroke ratio cut-off
Valve will be grown, so throttling control is than shut-off valve hardly possible.There is the place being distinctly claimed to adjusting, is neither suitble to.
Summary of the invention
The purpose of the present invention is to overcome the shortcomings of the existing technology, provides a kind of novel anti-misoperation formula plunger valve.For reality
The existing above-mentioned purpose present invention uses following technical scheme：
A kind of novel anti-misoperation formula plunger valve, including it is handwheel, valve rod, fastening spring, fixed block threaded rod, valve body, plunger, close
Seal, valve deck, valve stem nut, handwheel are fixedly mounted on valve stem tip by nut, fastening spring, valve rod are set on the valve rod body of rod
It being fixedly mounted in valve deck by valve stem nut, valve rod is connect by fixed block with threaded rod, and threaded rod tip is welded with plunger,
Sealing ring is sleeved on threaded rod lower end, and valve body and valve deck are fixed by fastening bolt.
Preferably, the valve rod bottom end is welded with connecting pin.
Preferably, the fixed block center offers the pin hole being correspondingly arranged with connecting pin.
Preferably, the connecting pin pin shaft volume is less than pin hole volume.
Compared with prior art, the present invention has the following advantages that：A kind of novel anti-misoperation formula plunger valve is suitable for anti-error
The working environment of operation, valve rod separate in the case where no operation with threaded rod, and rotation handwheel cannot achieve manually in this way
Operation, fixed block center offers the pin hole being correspondingly arranged with connecting pin, when needing to operate plunger valve, presses down on hand
Wheel, then rotates handwheel, and connecting pin sink to pin hole, and fine rotation operation, the pin rod of pin shaft is fixed, and rotates hand at this time
Take turns the operation, it can be achieved that plunger valve.

Specific embodiment
The present invention is further elaborated in the following with reference to the drawings and specific embodiments.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of novel anti-misoperation formula plunger valve, including handwheel 1, valve rod 2, fastening
Spring 3, fixed block 4, threaded rod 5, valve body 6, plunger 7, sealing ring 8, valve deck 9, valve stem nut 10, handwheel 1 are fixed by nut
It is mounted on 2 top of valve rod, fastening spring 3 is set on 2 body of rod of valve rod, valve rod 2 is fixedly mounted on valve deck 9 by valve stem nut 10
Interior, valve rod 2 is connect by fixed block 4 with threaded rod 5, and 5 top of threaded rod is welded with plunger 7, and sealing ring 8 is sleeved on threaded rod 5
Lower end, valve body 6 are fixed with valve deck 9 by fastening bolt.
2 bottom end of valve rod is welded with connecting pin 11.
4 center of fixed block offers the pin hole 12 being correspondingly arranged with connecting pin 11.
The 11 pin shaft volume of connecting pin is less than 12 volume of pin hole.
Working principle of the present invention：A kind of novel anti-misoperation formula plunger valve is suitable for fool proof working environment, valve rod
It is separated in the case where no operation with threaded rod, rotation handwheel cannot achieve operation manually in this way.Valve rod side is welded with
Connecting pin, fixed block center offers the pin hole being correspondingly arranged with connecting pin, when needing to operate plunger valve, presses down on
Then handwheel rotates handwheel, connecting pin sink to pin hole internal diameter, and fine rotation operation, the pin rod of pin shaft is fixed, and fastens bullet
Spring does the effect of fastening valve rod.Complete the connection of valve rod and threaded rod at this time, then manually rotation handwheel, it can be achieved that plunger valve
Operation.
Present apparatus design is suitable for fool proof working environment, avoids the normal work that valve is influenced because of maloperation.
The above is present pre-ferred embodiments, for the ordinary skill in the art, according to the present invention
Introduction, in the case where not departing from the principle of the present invention and spirit, changes, modifications, replacement and change that embodiment is carried out
Type is still fallen within protection scope of the present invention.
