Abstract
The invention provides a PE gate valve. The PE gate valve comprises a valve body, a valve deck, a valve rod, a gate board and a hand wheel, wherein the valve rod is connected with the gate board and the hand wheel, a metal inner sleeve and a metal base are inlaid inside the valve body, protruding blocks are arranged at the two sides of the upper portion of the gate board respectively, a shoulder portion is arranged on the metal inner sleeve, and a deformable sealing ring is arranged on the shoulder portion. The PE gate valve of the structure is good in leakproofness, the upper end and the lower end of the gate board are sealed through elastic components, butt joint errors can be corrected through the function of elasticity of the elastic components, and therefore the requirement for machining accuracy of the PE gate valve can be lowered.
Description
Technical field
The present invention relates to valve field, a kind of PE gate valve of special design.
Background technique
At daily life or industrial water, gas, oil pipe line, much adopt plastic materials, as PE material, the advantages such as resistance is little, serviceability is good that it has, are widely used at present.
While use PE pipeline, need gate valve also corresponding use PE material, more easily dock with pipeline like this.
Chinese patent application CN03228931.6 discloses a kind of Plastic sluice valves, as shown in Figure 1, it comprises valve body 1, valve gap 3, valve rod 4, flashboard 2 and handwheel 5, and valve gap 3 is connected with valve body 1, and flashboard 2 is positioned at valve body 1, valve rod 4 is through valve gap 3, be connected with flashboard 2 by screw thread, outer end and handwheel 5 are connected, and valve body 1 is made up of with the metal insert 12 be embedded in inside body the body 11 of plastic support, valve gap 3 connects with metal insert 12, and the sealing surface 13 in gate valve is positioned on metal insert 12.The Plastic sluice valves that this patent provides, have and be convenient to install, reduce the advantage of cost, but it also exists shortcoming, in use, as needed closing gate valve, flashboard moves down, and is combined by flashboard upper end part and end portion with metal inlay simultaneously, formed airtight, this needs very high machining accuracy, as flashboard upper end part and end portion can not close simultaneously, then produces water leakage phenomenon.
Summary of the invention
In order to overcome above-mentioned technical problem, the invention provides a kind of PE gate valve, it comprises valve body, valve gap, valve rod, flashboard and handwheel, valve rod connects flashboard and handwheel, wherein, described valve inner is inlaid with inner metal sleeve and metallic base, is provided with casting lug thereon in both sides, valve plate top, described metal 1 is provided with a shoulder, above shoulder, is provided with deformable seal circle.
Preferably, flashboard is made up of three parts, the columnar part of the columnar part on top, the wedge type portion at middle part and bottom.
Preferably, metallic base is provided with opening, and opening is made up of the wedge opening on top and the column opening of bottom, corresponding with bottom shape with in the middle part of flashboard.
Preferably, column open bottom is provided with projection, and projection is semi-cylindrical hill.
Preferably, semi-cylindrical hill is multiple, and diameter is 1-2mm.
Preferably, semi-cylindrical hill, diameter is 3-5mm.
Preferably, the thickness in cylindrical spring portion is 3-6mm.
Preferably, valve body outside is PE material.
Beneficial effect of the present invention: valve mechanism provided by the invention, it has good seal, its flashboard top and bottom are all airtight by elastic member parts realize, the elastic reaction of elastic member, the error to connecting can be revised, therefore, itself machining accuracy can lower the requirement.

Figure 1 shows that the structural representation of the PE gate valve of prior art
Figure 2 shows that the structural representation of PE gate valve of the present invention
Embodiment
The present invention will be described in detail for composition graphs 2.Just illustrate part-structure in Fig. 2, the transformation of flashboard and embedded external member is core of the present invention, gate valve routine as parts such as valve body, valve gap, handwheel, water intake, water outlets, omit in this figure, repeat no more.
PE gate valve of the present invention, it comprises valve body, valve gap, valve rod 22, flashboard 23 and handwheel, valve rod connects flashboard 23 and handwheel, valve body is PE material, inner metal sleeve 21 and metallic base 26 is inlaid with at valve inner, be provided with casting lug thereon 24 in both sides, flashboard 23 top, described inner metal sleeve 21 be provided with a shoulder 211, above shoulder 211, be provided with deformable seal circle 25.Flashboard 23 is made up of three parts, the columnar part C of the columnar part A on top, the wedge type portion B at middle part and bottom.The shoulder of inner metal sleeve 21 and rams contact face are also vertical surfaces.
Flashboard 23 decline throttle down time, the sealing on flashboard top is realized by 2 links.First, the columnar part A on flashboard top and the shoulder 211 of inner metal sleeve 21 fit tightly, and itself has sealing function; Simultaneously when flashboard moves down time, its casting lug thereon 24 can be depressed into variability seal ring 25, deformable seal circle 25 can produce distortion under pressure, and this is out of shape because other three directions do not allow (above-below direction distortion is stoped by inner metal sleeve by shoulder and casting lug thereon prevention, outwards distortion), can only to internal strain, namely towards the direction of extruding flashboard, thus sealing function is reached.
On the other hand, metallic base 22 is provided with opening 29, opening is made up of the wedge opening on top and the column opening of bottom, and opening shape is corresponding with bottom shape with in the middle part of flashboard.
Columnar part bottom flashboard is a spring section, and be namely a cylindrical spring portion 28 bottom flashboard, the thickness of spring section is 3-6mm, be preferably 5mm, corresponding, be provided with protruding 27 in column open bottom, projection is semi-cylindrical hill 27, and diameter is 3-5mm, is preferably 4mm.In other embodiments of the present invention, semi-cylindrical hill also can be multiple, and diameter is 1-2mm.
When flashboard 23 declines throttle down time, the sealing of flashboard bottom is also realized by 2 links, and the wedge type portion B first in the middle part of flashboard wants to mate with the wedge opening on opening 29 top, realizes sealing; Simultaneously owing to being provided with cylindrical spring portion 28 bottom flashboard, when decline, this cylindrical spring portion 28 can enter in the column opening of opening 29, and want to contact with protruding 27, more specifically, this projection 27 can be embedded in cylindrical spring portion 28, forms the effect reaching sealing.
Flashboard provided by the invention, first valve body is originally as PE material, and well can dock with common pipe, cost also reduces greatly.Meanwhile, valve mechanism provided by the invention, it has good seal, its flashboard top and bottom are all airtight by elastic member parts realize, and the elastic reaction of elastic member, can revise the error to connecting, therefore, itself machining accuracy can lower the requirement.Meanwhile, the seal of elastic member itself, to what generally acknowledge, therefore, after adding elastic member, the sensitivity for the closedown of whole gate improves greatly.
