Abstract
The utility model relates to a pressing fluid sluice valve, which comprises an inflow pipe, an outflow pipe, a valve rod, a guiding pipe, a valve pocket socket connected with the valve rod, a valve cap covering on the valve pocket, a spring rod of which an end is connected inside the valve cap, a spring, a pillar valve core connected with the other end of the spring and a elastic switch gasket which sleeves the spring rod and of which the periphery is pressed against the valve rod edge by the valve pocket. The utility model is characterized in that the elastic switch gasket divides the valve cavity into two parts; the fluid can only flow into the cavity formed by the inflow pipe, the outflow pipe and the pillar valve core and the fluid can not flow into the cavity which comprises the upper end of the spring rod and the spring, thus the fluid can not overflow where the spring rod and the valve pocket joint; the seal effect is good and the period of usage can be lengthened greatly; a leakage proofing device of the valve where the spring rod and the valve pocket joint is reduced and the manufacturing cost can be reduced.
Description
(1) technical field
The utility model relates to fluid line switch gate valves such as a kind of liquid, gas (vapour) body.
(2) background technique
Present liquid, gas (vapour) gate valve, when it is opened, fluid is full of whole valve pocket, after valve uses a period of time, fluid easily from valve shaft and valve pocket etc. binding site overflow, cause scrapping of whole valve, this is the main cause that the fluid gate valve is scrapped, simultaneously, and for leakproof, also leakage protection device to be set, increase cost of production.
(3) model utility content
At the above-mentioned deficiency of existing gate valve, the binding site that the utility model provides a kind of fluid not enter valve shaft and valve pocket etc., thus cancel leakage protection device simultaneously, the fluid gate valve that reduces production costs the working life of improving valve.
The technological scheme that realizes above-mentioned purpose is: it comprises the influent stream pipe, outflow tube, the valve rod that links to each other with outflow tube with the influent stream pipe and connect with one, interior sky that the influent stream pipe that links to each other with outflow tube with the influent stream pipe in valve rod and connect with valve rod or another pipe of outflow tube are connected is the honeycomb duct of platform shape, the valve pocket that socket-connects with valve rod, be placed in the bonnet on the valve pocket, one is terminated at the spring stack in the bonnet, be placed in the spring on the spring stack, be connected to the interior corresponding stage body spool of platform shape of the spring stack the other end and honeycomb duct and on spring stack, also be with periphery is pressed on valve rod end limit by valve pocket elastic switch pad.
The utility model is with periphery is pressed on valve rod end limit by valve pocket elastic switch pad on valve rod, valve pocket is separated into two parts, fluid only enters the valve pocket that influent stream pipe, outflow tube, honeycomb duct, stage body spool, elastic switch pad are constituted, thereby fluid can not overflow from the binding site of valve shaft (the utility model is a spring stack) and valve pocket etc., on valve shaft, leakage protection device need be set, improve the working life of valve, reduced cost of production.
(4) description of drawings
Fig. 1 looks sectional view for the utility model master.
(5) embodiment
Be described further below in conjunction with accompanying drawing, but be not limited only to this.
As shown in Figure 1, the utility model comprises influent stream pipe 11, outflow tube 12, the valve rod 13 that links to each other with outflow tube 12 with influent stream pipe 11 and connect with outflow tube 12, in valve rod 13, link to each other with outflow tube 12 and be the honeycomb duct 10 of platform shape with the interior sky that influent stream pipe 11 is connected with influent stream pipe 11, the valve pocket 4 that socket-connects with valve rod 13, be placed in the bonnet 1 on the valve pocket 4, one is terminated at the spring stack 3 in the bonnet 1, be placed in the spring 2 that two ends on the spring stack 3 contact with valve pocket 4 with bonnet 1 respectively, be connected to spring stack 3 the other ends and the honeycomb duct 10 interior corresponding stage body spools 9 of platform shape and on spring stack 3, also be with periphery is pressed on valve rod 13 end limits by valve pocket 4 elastic switch pad 7.Elastic switch pad 7 and spool 9 are located on spring stack 3, adopt the mode that shaft shoulder shimming nut links is set respectively on spring stack 3.The common state of this valve is a closed condition, when needs are opened, depresses bonnet 1, and spring stack 3 promotes spool 9 and leaves honeycomb duct 10, opens gate valve first, unclamps bonnet 1, and gate valve is got back to closed condition again.7 on elastic switch pad seals.
Claims (1)
1, a kind of pressure type fluid gate valve, comprise influent stream pipe (11), outflow tube (12), the valve rod (13) that links to each other with outflow tube (12) with influent stream pipe (11) and connect with one, interior sky that the influent stream pipe (11) that links to each other with outflow tube (12) with influent stream pipe (11) in valve rod (13) and connect with valve rod (13) or another pipe of outflow tube (12) are connected is the honeycomb duct (10) of platform shape, the valve pocket (4) that socket-connects with valve rod (13), be placed in the bonnet (1) on the valve pocket (4), one is terminated at the spring stack (3) in the bonnet (1), be placed in the spring (2) on the spring stack (3), be connected to spring stack (3) the other end and the corresponding stage body spool of the interior platform shape of honeycomb duct (10) (9), it is characterized in that: on spring stack (3), also be with periphery is pressed on valve rod (13) end limit by valve pocket (4) elastic switch pad (7).
