Q:What's the difference between the H76H model and the H76J check valve?
Check valve additional number: HH, micro resistance, slow closing check valve, BH Insulation check valve, HQ ball type check valve;The check valve type: H on behalf of check valve;The check valve flange connection: 4, 6, 7 for welding clamp;The check valve: 1 lift, 2 vertical, 4 swing, 6 double disc, 8 butterfly;The check valve seal: B Babbitt, F fluorine plastic, H stainless steel, Monel alloy, cast M direct machining of X rubber, Y hard alloy, W;The check valve pressure: 16 pressure of sixteen kg,
Q:What is the difference in price between the check valve HH48X-10C and the HH49X-10C?
Since this model has exceeded the standard requirements, so there is no uniform manufacturers. There are dozen HH49X, there are also playing HH48X, HH49X, in fact, are the same kind of valve.
Q:Are the gate valves and check valves of the same type?
It is a kind of valve opening and closing function (i.e. switch) of the valve, it is on the gate lifting and play the role of the switch, the switch is to be applied by external force (hand wheel, electric, pneumatic and hydraulic) it is not required to;Check valve is a check valve function, is to prevent the media back, it is by the valve on the pin shaft and the rotary switch to play the role of the valve with different things, when it is opened by medium pressure automatic opening, closing time depending on the medium and back type the self gravity valve closed, it is a kind of automatic gate valve function, does not require an external force is applied to it, it is a demand for the direction.
Q:Can the swing check valve stand upright?
Swing check valve, vertical mount, horizontal loading can be.
Q:Circulating water check valve, I want to ask is not greater than DN600, you can use HBH747H hydraulic butterfly valve closed butterfly valve, less than DN600 of HD43X slow butterfly butterfly check valve, what does hydraulic check mean? Need hydraulic?
Greater than DN600, you can use HBH747H hydraulic butterfly butterfly valve closed, less than DN600 with HD43X slow butterfly butterfly check valveThis is the usual selection, not necessary, there is no provision, but this choice is not wrong. There are, of course, other types of check valves.The hydraulic check valve is hydraulic, and the Baidu library contains instructions for the HB series and the HD series hydraulic check valves
Q:Should the kitchen check be mounted on the wall or on the hood?
Buy their own check valve is generally in the wall of the hole, the hood of the smoke machine, usually with a check valve.
Q:What type of check valve is the h61y-40 check valve?
I. lift check valves: check valves that slide along the vertical centerline of the valve body. The lift check valves can only be installed on the horizontal pipe. The disc can be used in the high pressure small bore check valve. The valve body of the lift check valve is the same as the cut-off valve (which can be used with the stop valve), so it has a large coefficient of fluid resistance. The structure is similar to the cut-off valve, the valve body and the disc are the same as the cut-off valve. The lower part of the upper valve and the valve cover processing guide sleeve, the valve in the valve lift free guide simple simple light driven, when the medium downstream, the valve thrust open by the media, when the media stopped flow, the valve by the self vertical landing on the seat, preventing the media from the upstream effect. Straight through lift type check valve medium channel with import and export channel direction perpendicular to the valve seat; vertical lift check valve, the media import and export channel in the direction of the same direction with the valve seat, the flow resistance is smaller than the straight through.
Q:How to install the water pipe check valve?
If the pipe in the installation position is vertical, you can choose the swing type and pipe type!If the installation position of the pipe is horizontal, you can choose the lifting type!Lift check valve opens and stops at the fastest speed!The swing check valve has the least resistance!
Q:Only one is a soft seal and one is hard sealed
Not the same model. The rubber valve check is HC44X, and the swing check valve is H44H
Q:What is the difference between check and check valves? Check and check valves?
3, swing type: liquid in the valve straight through, relying on the pressure to open the side of the rotating valve flap, after the loss of pressure, the valve depends on the weight back, the reverse of the liquid pressure closed valve. Other one-way valves (check valves), such as the sewage check valve, air defense explosion-proof valve and liquid use of the principle of the check valve is very similar
