Q:What if the function of a valve retainer?
Valve Spring Retainer
Q:Im replacing the valve stem seals from my 1991 jaguar xj6 and the valve dropped?
As you've been asking this question for a week now time and time again I guess its time for the Nasty one to set you straight, As I've been a mechanic for over 30 years my knowledge is vast and no further questions need to be asked, You screwed up! now that you have dropped the valves into the cylinders you have to remove the head or heads that you screwed up on, period, end of sentence, there is no other way, and no you will not need to remove the engine to remove the heads, But had you did a bit of research before diving into this without a clue you would have found that a simple length of clothes line or thin rope stuffed down the spark plug hole and turned the engine over by hand to bring the piston up and push the rope into the valves to hold them place would have saved you from pulling the heads off this POS, excuse me I meant fine piece of English engineering, by trying to turn the engine over now is just a good way to bend a valve, and for all you know the piston could have been at the bottom of its stroke and the valves fell out of there guides are not even in contact with the head, so with this said do some research on how to remove the heads on this thing and fix your screw up. Live and learn, you just opted to learn the hard way,
Q:Will A Stop Valve Switch Off Water In The Bathroom Only
Water should be off to the sink is the stop valve off
Q:What is an electric two position butterfly valve?
It's an electric valveProduct brief:  Electric double position butterfly valve, this product is connected with flange type, clip type. Material: cast iron, carbon steel, stainless steel, 304/316Product overview   Electric double position butterfly valve (soft seal) is suitable for temperature less than 200 DEG C, adjust the flux and closure of the role of the medium nominal pressure is less than 1.6MPa of food, medicine, chemical, petroleum, electric power, textile, papermaking, water supply and drainage, gas pipeline.  main features1 reasonable and novel design, unique structure, light weight, rapid opening and closing.2 operating torque is small, easy to operate, saving smart.3 can be installed in any position, convenient maintenance.4 seals can be replaced, reliable sealing performance to achieve two-way seal zero leakage.5 sealing material aging resistance, corrosion resistance, long service life etc..Electric double position butterfly valve adopts standardDesign standard: GB/T12238-1889Flange size: GB/T9113.1-2000; GB/T9115.1-2000; JB78Length: GB/T12221-1889Pressure test: GB/T13927-1992; JB/T9092-1999
Q:How to connect the signal butterfly valve?
The signal butterfly valve should be the surveillance and alarm of human action. Once it is closed, it will alarm the system.Signal butterfly valve wiring method:1, open the switch box cover, according to the electrical control requirements, the cable core line to the corresponding terminal, and sealed cable imports, while the cable fixed, to prevent external force damage when the cable wiring.2, when the valve in the "closed" position, the clockwise rotation of the following relationship to the cam is just touch micro switch cam (you can hear the clicking sound), and then tighten the screw on the cam cam.3, when the valve in the "fully open" position, counterclockwise turn the upper open cam, with the same method to adjust the open cam.4, adjust the limit screw, when the valve in the "full off" or "open" position, should not make the limit screw just at the top of the worm gear limit plane, and should have a certain gap, and then tighten the lock nut on the screw.5, on the cover of the electrical switch box cover, when the valve in the "off" position, the pointer opening indicator to dial "0" scale, and tighten the screws pointer.
Q:How does the pneumatic butterfly valve control the angle of opening?
The angle of the rotating shaft is controlled so that the angle of the butterfly valve is controlled. You just have a good electrical locator
Q:Butterfly valve in the use of the difference? Caliber?
Role of butterfly valveButterfly valve is to use disc type to open and close parts reciprocating reciprocating about 90 degrees to open, close or adjust the flow of medium valve. The butterfly valve has the advantages of simple structure, small volume, light weight, material consumption, installation of small size, the driving performance of torque is small, simple operation, rapid, high chemical corrosion, and can also have good flow control function and closure characteristics, the use of butterfly valve is very extensive. Its varieties and quantities are still expanding, and the development of high temperature, high pressure, large caliber, high sealing, long life, excellent regulation, as well as multi-function development of one valve. Its reliability and other performance indicators have reached a high level. Disadvantages, there is a certain resistance to the medium.Gate valves are more used in steam pipes and large diameter water supply pipelines, because of the general requirements of fluid resistance is small, the use of gate valve.Valve is hand wheel rotation, stem upward movement. Flow is not the same, the gate valve requires full open. Need a higher installation space, the valve sealing surface has a certain self sealing capacity, its spool by the media pressure closely with the valve seat sealing surface contact, to achieve tight leakage. Wedge gate valve spool angle is generally 3~6 degrees, when forced to shut down excessive or temperature changes of the valve core is easy to die. Therefore, high temperature and high pressure wedge gate valve, in the structure have taken certain measures to prevent spool stuck. The valve in the opening and closing valve and valve seat sealing surface contact and mutual friction is always so easy to wear sealing surface, especially in close off the valve, the valve before and after the great pressure, sealing surface wear is more serious.
Q:What type of valve does the butterfly valve D343X DN300 represent?
D butterfly valve3 worm gear drive4 flange connection3, three eccentric structureX the rubber cover is rubberAccording to JB/T308-2004< valve model compilation method >
Q:What are single eccentric and double eccentric in butterfly valves? What's the difference, please explain in detail?
Double eccentric butterfly valve: in the single eccentric butterfly valve on the basis of further improvement of forming, is the most widely used double eccentric butterfly valve. The structure features that the center of the stem deviates from the center of the disc as well as the center of the body. The effect of the double eccentric valve can be opened immediately after the disc from the valve seat, substantially eliminating the unnecessary disc and valve seat over squeezing, scratching phenomenon, reduce the resistance from the open, reducing the wear and improve seat life.
Q:Butterfly valve D71X-1.6C, DN50, there is no difference between C and no C? What do you mean by "concrete"?
Front is the same, there is C refers to the body of the material is carbon steel, without C, usually refers to gray iron (cast iron is more common, so are generally omitted)
