SELF-CLOSING COCK HEAD WITH PEDAL TYPE

We are not familiar with the sounding self closing valve, which is one of the components of the sounding device in the ship standard CB / t37478-199:

In order to facilitate operation, we have designed an upgraded product based on CB / t3778-99 sounding self closing valve:

Foot type sounding self closing valve with extension rod
Note: the extension rod here can be customized according to customer requirements.
Working principle of this foot type sounding self closing valve with extension rod:

The Marine Sounding self closing valve is mainly used to install on the pipeline of the ship's low-pressure gas system. When the supply pressure of the ship's pipeline is under pressure or over pressure, it can be automatically closed and manually opened without electricity or other external power.
CB / t3778-99 Marine Sounding self closing valve, foot type sounding self closing valve with extension rod can be marked as follows according to the difference of nominal diameter:

Fh-dn40 Marine Sounding self closing valve, foot type sounding self closing valve with extension rod Dn40 CB / t3778-99
Fh-dn50 Marine Sounding self closing valve, foot type sounding self closing valve with extension rod DN50 CB / t3778-99
Fh-dn65 Marine Sounding self closing valve, foot type sounding self closing valve with extension rod DN65 CB / t3778-99
Fh-dn80 Marine Sounding self closing valve, foot type sounding self closing valve with extension rod DN80 CB / t3778-99

Marine Sounding self closing valve - Marine self closing measuring pipe head
Today, we will give you a brief introduction to the sounding self closing valve in the components of the ship sounding device.
First, let's take a look at the installation method of this sounding self closing valve on the ship:

It can be seen from the above figure that it is installed on the pipeline more than 750mm above the deck, so as to realize convenient and rapid measurement of the liquid level of the ship's oil tank.

Next, let's understand the working principle of CB / t3778 Marine Sounding self closing valve:

It is mainly used to install on the pipeline of the ship's low-pressure gas system. When the supply pressure of the ship's pipeline is under pressure or over pressure, the vent cock at the tail of the sounding self closing valve will pop up automatically, so as to realize automatic closing. It needs to be started manually when it is restarted.

CB / t3778-99 components of Marine Sounding self closing valve:
It consists of: self closing valve body, self closing valve hammer handle, switching valve core and head cap.

According to different installation positions, DN65 Marine Sounding self closing valve can be selected and marked as:

Fh-65a CB / t3778-1999 sounding self closing valve for marine chain locker
Marine sewage treatment bronze sounding self closing valve fh-65 (ACB / t3778-1999)
