Abstract
The utility model belongs to the field of valves and discloses a double-parallel-plate floating type valve clack structure for a gate valve. The double-parallel-plate floating type valve clack structure comprises a valve body, double flat plates, springs, limiting blocks, a valve rod, valve clack supports, taper pins and valve seats. The double flat plates are arranged in the valve body and include a left valve clack and a right valve clack, the left valve clack and the right valve clack are symmetrically arranged in parallel, opposite faces of the left valve clack and the right valve clack are provided with an upper containing groove and a lower containing groove, the springs are radially arranged in the containing grooves, the left valve clack and the right valve clack fit seal faces of the valve seats, the valve rod is fixedly connected with the valve clack supports through the taper pins, the limiting blocks are arranged in the valve clack supports, an inner groove is formed in the lower end of each limiting block, the inner sides of the left valve clack and the right valve clack are provided with steps, and the left valve clack and the right valve clack are in clamped connection with the inner grooves of the limiting blocks. The double-parallel-plate floating type valve clack structure for the gate valve has the advantages parts of a valve clack seal structure are separated, airtightness can be guaranteed even under the condition of deformation resulted from temperature variation, and the problem of failure in opening of the valve clacks duo to the fact that the valve clacks are squeezed because of high-temperature expansion is solved.
Description
Technical field
The utility model relates to valve field, is specifically related to a kind of two floating type valve flap structure of parallel flat gate valve.
Background technique
Gate valve is used on steam line, vapor (steam) temperature is up to 400 DEG C, owing to being worst hot case, between the each part of valve seal mechanism, easily cause part deformation, cause valve seal to lose efficacy, or because choking flap, high-temperature expansion do not open, traditional gate valve generally can only apply active force by operating valve lever in the Vertical direction of pipeline, and it is for along conduit axis direction, be that the active force that forms sealing between the flashboard of gate valve and valve seat is not but contributed, thereby cause the sealing between flap and valve seat poor.Disclosed China Patent No. is 201020649877.0 " a kind of parallel gate valve ", it has disclosed the sealing configuration of two parallel flaps and valve seat, but, sealing complicated structure, adopt bivalve sleeve-board engaging flap, valve plate cover is to be fixedly connected with, and flap is also fixedly connected with valve seat, has high-temperature expansion and makes flap be choked the problem of not opening by valve plate cover and valve seat.
Model utility content
The technical solution of the utility model is as follows:
A kind of two floating type valve flap structure of parallel flat gate valve, comprise valve body, two flat boards, spring, limiting stopper, valve rod, flap supports, taper pin and valve seat, described pair of flat board is placed in valve body, described pair of flat board comprises left flap and right flap, left flap and right flap are parallel to each other and are symmetrical arranged, on described left flap and right flap opposing side, be provided with upper and lower two receiving grooves, described spring is radially arranged in receiving groove, it is characterized in that, the sealing surface laminating of described left flap and right flap and valve seat, described valve rod supports and is fixedly connected with by taper pin with flap, described limiting stopper is placed in flap support, described limiting stopper lower end is processed with inside groove, the inner side of described left flap and right flap is provided with step, described left flap and right flap are blocked and are connected with the inside groove of limiting stopper by step.
The utility model compared with prior art, simple in structure, and the each part of valve clack sealing structure is separated from each other, even if cause that in the time of temperature variation deformation also can ensure sealing, and can not make flap choke because of high-temperature expansion and not open, simultaneously floating type flap can automatic calibration, laminating sealing surface of seat.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the two floating type valve flap structure figure of the parallel flat gate valve schematic diagram of the disclosed one of the utility model embodiment;
Numeral and the represented corresponding part title of letter in figure:
1, valve body; 2, left flap; 3, right flap; 4, spring; 5, limiting stopper; 6, valve rod; 7, flap supports; 8, taper pin; 9, valve seat.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment who obtains under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment
A kind of two floating type valve flap structure of parallel flat gate valve, comprise valve body 1, two flat boards, spring 4, limiting stopper 5, valve rod 6, flap supports 7, taper pin 8 and valve seat 9, described pair of flat board is placed in valve body 1, described pair of flat board comprises left flap 2 and right flap 3, left flap 2 and right flap 3 are parallel to each other and are symmetrical arranged, on described left flap 2 and right flap 3 opposing sides, be provided with upper and lower two receiving grooves, described spring 4 is radially arranged in receiving groove, described left flap 2 and right flap 3 are fitted with the sealing surface of valve seat 9, described valve rod 6 supports 7 with flap and is fixedly connected with by taper pin 8, described limiting stopper 5 is placed in flap and supports in 7, described limiting stopper 5 lower ends are processed with inside groove, the inner side of described left flap 2 and right flap 3 is provided with step, described left flap 2 and right flap 3 are blocked and are connected with the inside groove of limiting stopper 5 by step.Left flap 2 and right flap 3 pack into after valve seat 9, owing to leaving compensation surplus between flap support 7 and flap, under the thrust of spring 4, the sealing surface laminating of flap and valve seat 9, in actual production, the parallelism of 9 of valve seats has deviation unavoidably, now flap can produce micro-movement, structure of the present utility model can automatic calibration the sealing surface of laminating valve seat 9, realize low pressure seal, the each part of valve clack sealing structure is separated from each other, even if cause that in the time of temperature variation deformation also can ensure sealing, and can not make flap choke because of high-temperature expansion open, thereby extend the working life of valve.
Above-described is only the preferred implementation of a kind of pair of floating type valve flap structure of parallel flat gate valve of the utility model; should be understood that; for the person of ordinary skill of the art; do not departing under the prerequisite of the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
