Description
Technical Field
The utility model relates to a steel cylinder valve technical field specifically indicates a steel cylinder valve suitable for fuel methyl alcohol.
Background
Because of the low economic cost, methanol is gradually popularized and used in the gas industry. Under natural conditions, the saturated vapor pressure of the methanol is lower, and the liquid methanol is not discharged and supplied to the gas cooker. Therefore, a certain amount of compressed non-combustible and non-combustion-supporting gas needs to be filled into the steel cylinder, and the operation is called 'gas supplement' in the industry for short. The added pressure gas source is not suitable for directly ventilating liquid methanol, and only one additional air supplement port is used for supplementing air.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a steel cylinder valve suitable for fuel methyl alcohol.
The technical scheme adopted for solving the technical problems is as follows: the utility model provides a methanol valve, includes the valve body of threaded connection steel bottle, opens one side of valve body has the interface of connecting the gas pipeline, and the valve body top is fixed with the valve gap, wears to be equipped with the valve rod on the valve gap, and the outer end of valve rod is fixed with the hand wheel, is formed with the valve port of intercommunication interface in the valve body, is equipped with on the valve port with valve body screw-thread fit's the valve that is used for the switch valve port, cartridge circumference fixed connecting block, its characterized in that between the inner of valve and valve rod: the side of the valve body is also provided with an air supply valve body, a one-way valve for preventing leakage is arranged in the air supply valve body, the outer end of the air supply valve body is connected with an air supply joint, and the side wall of the valve body is internally provided with a vent hole for communicating the air supply valve body and the steel cylinder.
On the basis, the check valve is a duplex check valve.
On the basis, the outer end of the air supply valve body is provided with a straight port and a lateral port, a plug used for blocking and sealing is installed in the straight port, and the air supply joint is installed at the lateral port.
The port of the valve body, which is connected with the steel cylinder, is connected with a liquid phase pipe which is directly connected to the bottom of the steel cylinder.
Adopt the utility model discloses the beneficial effect who brings: the utility model discloses methanol valve's simple structure, it is with low costs, the separation is sealed effectual moreover, is applicable to very much and fills the installation on the steel bottle of dress methyl alcohol.
Drawings
Fig. 1 is a schematic structural diagram of the methanol valve of the present invention.
Detailed Description
As shown in figure 1, the main body of the methanol valve is a conventional switch valve of a steel cylinder, and comprises a valve body 1 in threaded connection with the steel cylinder, a connector 1.1 connected with a gas pipeline is arranged on one side of the valve body 1, a valve cover 2 is fixed on the top of the valve body 1, a valve rod 3 is arranged on the valve cover 2 in a penetrating manner, a hand wheel 4 is fixed at the outer end of the valve rod 3, a valve port 1.2 communicated with the connector is formed in the valve body 1, a valve 5 which is in threaded fit with the valve body 1 and used for switching on and off the valve port 1.2 is arranged on the valve port 1.2, and a connecting block 6 which is circumferentially fixed is inserted between the valve 5 and the inner end of the valve rod 3. The utility model discloses in, the lateral part of valve body 1 still is formed with the gulp valve body 1.3, installs the check valve 7 that prevents to leak in the gulp valve body 1.3, and the outer end of gulp valve body 1.3 is connected with tonifying qi and connects 8, opens the air vent 1.4 that has intercommunication gulp valve body 1.3 and steel bottle in the lateral wall of valve body 1.
The utility model discloses methanol valve's conventional main part can provide filling dress and the air feed of methyl alcohol. After the methanol is added, the methanol valve is closed, the pipeline joint connected with the compressed gas source is connected to the gas supplementing joint 8, the pressure of the compressed gas in the gas supplementing valve body 1.3 jacks the check valve 7, and the compressed gas enters the gas phase space of the steel cylinder through the vent hole 1.4 to supplement gas. When the pressure in the steel cylinder reaches a set value, the compressed gas source is pulled out, and the check valve 7 automatically resets to realize sealing. After the gas supply is completed, the normal gas supply of the methanol fuel of the steel cylinder can be realized.
In order to improve the sealing performance of the gulp valve, the check valve 7 is a duplex check valve. The duplex one-way valve is formed by connecting two one-way valves in series, so that a two-stage sealing effect is achieved.
In order to enable the structure of the air compensating valve to be more reasonable and have better operability, the outer end of the air compensating valve body 1.3 is provided with a straight port and a lateral port, a plug 9 for blocking and sealing is installed in the straight port, and an air compensating joint 8 is installed at the lateral port. The installation of end cap 9 can adopt jump ring 10 fixed, and installs sealing washer 11 additional.
In order to ensure the stability of the liquid phase of the methanol, the port of the valve body 1 connected with the steel cylinder is connected with a liquid phase pipe 12 which is directly connected to the bottom of the steel cylinder.
