Abstract
The utility model discloses a spring full-lift safety valve which comprises a valve seat, a valve body, a valve plug and a valve cover. The valve body is hollow and is provided with an air outlet, the valve seat is provided with an air inlet, the valve plug is arranged in the valve body, the valve body is connected with the valve seat in a screwing mode, the valve seat is provided with an adjusting ring, and a protective cover is arranged at the upper end of the valve cover in a covering mode. The spring full-lift safety valve is characterized in that the valve plug is formed by a valve rod, a spring seat connected with the lower end of the valve rod and a spring sleeved on the valve rod, one end of the spring butts against the spring seat, the other end of the spring butts against the lower end of the valve cover, a guiding sleeve is arranged at the lower end of the spring seat, the lower end of the guiding sleeve is connected with a recoil valve, a valve clack is arranged in the recoil valve, the lower end of the valve rod is arranged in the guiding sleeve, the upper end of the valve rod is connected an adjusting screw rod with a protective jacket arranged on the periphery, and the upper end of the adjusting screw rod is fixed through a nut and is connected with an outside wrench in a contacting mode. The spring full-lift safety valve has the advantages that the lower end of the valve rod in the recoil valve can be adjusted up and down, the valve clack is made to reach a best open state, and pressure relieving speed is high.
Description
Technical field
The utility model relates to the Safety valve technical field, particularly a kind of spring Fall lift safety valve.
Background technique
Safety valve is to use on the boiler equal pressure container; the control Maximum operating pressure, the valve of protective system device security work, the recoil valve inner valve stem lower end of existing Safety valve can not be adjusted in real time according to the medium working condition; flap does not reach best Lift, and the pressure mass rate of emission is slow.
The model utility content
The purpose of this utility model is at the defective of prior art and deficiency, and a kind of recoil valve can regulate, the fast spring Fall lift safety valve of pressure mass rate of emission are provided.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of spring Fall lift safety valve described in the utility model; comprise valve seat; valve body; spool; valve gap; empty and take gas port out of in the described valve body; valve seat has suction port; spool is set in the valve body; valve body screws with valve seat and is connected; valve seat is provided with Adjusting ring; the valve gap upper end buckles the described spool of safety cover by valve rod; the spring seat that links to each other with the valve rod lower end; the spring that is enclosed within on the valve rod is formed; spring one end and spring seat offset; the spring the other end and valve gap lower end offset; the spring seat lower end is provided with guide sleeve; the guide sleeve lower end connects recoil valve, is provided with flap in the recoil valve, and the valve rod lower end is arranged in the guide sleeve; the upper end connects the peripheral adjusting screw rod that is provided with protecting jacket, and transfer screw rod upper end is fixed by nut and is connected with the contact of outside spanner.
After adopting said structure, the utility model beneficial effect is: the valve rod lower end in the recoil valve can up-down adjustment, makes flap can reach best opening state, and the pressure mass rate of emission is fast.
