Abstract
The invention provides a rapid intercepting valve which comprises a valve body, a valve rod, a valve clack and a stuffing box. The valve rod penetrates through the stuffing box and stretches into the valve body, the stuffing box is fixedly connected with the valve body through a gland, stuffing is arranged between the stuffing box and the valve rod and is fixed and sealed through a stuffing gland, the front end of the valve rod is fixedly connected to the valve clack, the stuffing box is fixedly connected with a cylinder body, the cylinder body is divided into an upper cavity and a lower cavity through a piston, the other end of the valve rod is fixedly connected with the piston, a spring is arranged in the upper cavity, the lower cavity is connected with a power air source through a valve opening air inlet, and the two ends of the spring are fixedly connected with the piston and a cylinder cover respectively. The rapid intercepting valve has the advantages that when the rapid intercepting valve is in a work state, the power air source is used for enabling the piston to be lifted upwards under the pressure of air, therefore, the valve clack is driven to be lifted upwards to achieve opening of the valve, and the spring is compressed at the same time to store energy; when the power air source is closed, the valve clack is closed rapidly under the dual action force of pressure of back-flowed media and the pressure of the spring, the rapid intercepting function is achieved, and equipment and accessories are protected.
Description
Technical field
The present invention relates to a kind of valve, particularly relate to a kind of fast block valve.
Background technique
Block valve is the valve of being everlasting in the systems such as oil, chemical industry, steam line for the circulation of pilot line medium.Common block valve, by rotation hand wheel, rises valve rod and declines to drive flap to move, and reaches the object of valve opening and closing, and required moment is large, and power consumption is large, and reaction velocity is slow, can not realize fast shut-off.
Summary of the invention
In order to overcome the above-mentioned shortcoming of existing self-powering type safety check, the invention provides a kind of fast block valve little and that opening/shutting valve reaction velocity is fast that consumes energy.
The technical solution adopted for the present invention to solve the technical problems is a kind of fast block valve, comprise valve body, valve rod, flap, stuffing box, valve rod stretches in valve body through stuffing box, stuffing box is fixedly connected with valve body by gland, filler is placed between stuffing box and valve rod, by Gland fixing seal, valve rod front end is fixedly connected with flap, stuffing box is fixedly connected with a cylinder body, cylinder body is divided into epicoele and cavity of resorption by a piston, the valve rod the other end is fixedly connected with piston, spring is set in epicoele, cavity of resorption is connected with power gas source by opening valve suction port, both ends of the spring is fixedly connected with cylinder cap with piston respectively.
On cylinder cap, have keying spiracle.
While the invention has the beneficial effects as follows in working order, utilize power gas source that piston is upwards promoted under the pressure of gas, thereby drive flap upwards to promote, realize and drive valve, spring is compressed simultaneously, stored energy; When power gas source is closed, flap quick closedown under reflux medium pressure and spring double reaction plus, realizes fast shut-off function, protection equipment and annex.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is the present embodiment structural drawing
In Fig. 1: 1. valve body; 2. flap; 3. valve rod; 4. gland; 5. stuffing box; 6. filler; 7. Gland; 8. piston; 9. spring; 10. cylinder body; 11. cylinder caps; 12. open and close spiracle; 13. epicoeles; 14. cavity of resorptions; 15. open valve intake interface.
Embodiment
As shown in Figure 1, a kind of fast block valve, comprise valve body 1, valve rod 3, flap 2, stuffing box 5, valve rod 3 stretches in valve body 1 through stuffing box 5, stuffing box 5 is adopted and is threaded with valve body 1 by gland 4, compact structure, convenient for maintaining maintenance, filler 6 is placed between stuffing box 5 and valve rod 1, by Gland 7 fixing seals, valve rod 3 front ends are fixedly connected with flap 2, stuffing box 5 adopts transition to be threaded with a cylinder body 10, cylinder body 10 is divided into epicoele 13 and cavity of resorption 14 by a piston 8, valve rod 3 the other ends are fixedly connected with piston 8, the interior spring 9 that arranges of epicoele 13, cavity of resorption 14 is connected with power gas source by opening valve suction port 15, spring 9 two ends are fixedly connected with cylinder cap 11 with piston 8 respectively, on cylinder cap 11, have and open and close spiracle 12, make epicoele 13 pressure stabilitys, there will not be vacuum phenomenon.
During work, the source of the gas that turns on the power, enters in cavity of resorption 14 gas, and piston 8 upwards promotes under the active force of gas, drives flap 2 upwards to promote, and realizes valve opening, and meanwhile, spring 9 is compressed, stored energy; When closing power gas source, flap 2 is fast-descending under the double reaction plus of reflux medium pressure and spring 8, realizes valve speed and closes.
Claims (2)
1. a fast block valve, comprise valve body, valve rod, flap, stuffing box, valve rod stretches in valve body through stuffing box, stuffing box is fixedly connected with valve body by gland, filler is placed between stuffing box and valve rod, by Gland fixing seal, valve rod front end is fixedly connected with flap, it is characterized in that: described stuffing box is fixedly connected with a cylinder body, described cylinder body is divided into epicoele and cavity of resorption by a piston, the described valve rod the other end is fixedly connected with piston, in described epicoele, spring is set, described cavity of resorption is connected with power gas source by opening valve suction port, described both ends of the spring is fixedly connected with cylinder cap with piston respectively.
