If spring, valve deck is connected with bonnet upper end and upper end closed, the triangle spool of the utility model coordinates with valve seat to be stablized, entirely
The vertical one of component, reaches the stable effect of pressure, so as to fulfill valve body inlet and outlet connection or do not connect, it is whole safely
Valve arrangement practicality and spaces compact, material environment friendly and anti-yield strength height, greatly improve security.
To reach above-mentioned purpose, the technical solution of the utility model is：New totally-enclosed stainless steel safety valve, is three-body type
It is formed by connecting, including valve seat, valve body, spool, spring block, spring, valve rod, adjusting screw, valve deck, bonnet, the valve seat
Top is located in the inner cavity of valve body, and the valve body upper end connects bonnet, the internal thread connection adjusting screw of the bonnet upper end, institute
The hole for stating adjusting screw is connected with valve rod, and the valve rod extends downwardly rear bottom and sets spool, and the spool loads the passage of valve seat
The step of back valve core upper end covers the port of export of passage, and valve body lower end sets spring block, and adjusting screw lower end sets spring block,
Spring is set between the spring block of valve body lower end and the spring block of adjusting screw lower end, the valve deck is connected with bonnet upper end and handle
Upper end closed.
Further set, the spring is set in outside valve rod.
Further set, the valve seat, valve body, spool, spring block, spring, valve rod, adjusting screw, valve deck, bonnet material
Matter is stainless steel.
Further set, the valve seat, valve body, bonnet, the junction of valve cover chamber arrange polytetrafluoro material.
Further set, the passage connecting shaft of the spool and valve seat is triangular shape.
The beneficial effects of the utility model：The triangle spool of the utility model coordinates with valve seat to be stablized, and whole part is vertical
One, reaches the stable effect of pressure, so as to fulfill valve body inlet and outlet connection or do not connect, whole safety valve structure reality
With and spaces compact, material environment friendly and anti-yield strength are high, greatly improve security.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
In figure：Valve seat 1, passage 101, valve body 2, spool 3, spring block 4, spring 5, valve rod 6, adjusting screw 7, valve deck 8,
