Interference close fit is formed between the lip-shaped part of the double lip-shaped rubber sealing strip and the flashboard, thus preventing fluid medium at the internal direction and the external direction of the paddle valve from passing through, and realizing bidirectional water stopping effect. Foamed rubber sealing strips are arranged between the floodgate frame and the installation wall surface and between the sealing valve frame and the installation surface, which play the function of water stop. The paddle valve of the invention has simple and lightweight design structure, high strength, convenient installation and maintenance and good bidirectional water stopping effect; compression resisting safety factor is larger than 6; and the highest adaptive water pressure can reach 10 water heads.
Description
Technical field:
The present invention relates to a kind of valve, it relates to a kind of gate valve in particular.
Background technique:
Gate valve commonly used now generally includes lock frame, flashboard, in two vertical lock frames, is provided with guiding device, and flashboard moves up and down along guiding device, realizes closing and opening of gate.In use, owing to often be in Frotteurism, easy abrasion between flashboard and the guiding device; Guiding device is inaccurate to the location of flashboard, causes seal degree decline between flashboard and the lock frame, seepage occurs; Need change valve when serious, cause cost of production to increase.In addition, because in work progress, concrete wall surface is not very smooth, therefore often causes between lock frame and the concrete wall surface sealing effect bad, the seepage phenomenon can occur yet, and the gate valve two-way water stop effect of existing structure is not very desirable in a word.
Summary of the invention:
Technical problem to be solved by this invention is the deficiency that overcomes existing technology, and a kind of gate valve that a kind of two-way water stop is effective and be not easy to wear and tear is provided.
Technical problem to be solved by this invention can realize through following technological scheme:
A kind of gate valve comprises lock frame and flashboard, and said lock frame is combined by the two horizontal lock frames of vertical lock frame and upper, middle and lower that laterally arrange; In said vertical lock frame, be provided with guide rail, offer on the said guide rail and hold the guide groove that flashboard moves up and down, said lock frame is fixed in to be installed on the metope; It is characterized in that, on said lock frame, be fixed with the sealing valve buckle, the sealing valve buckle is a U font structure; Between flashboard and installation metope, the opening of this U font structure is equipped with a lips type rubber weather strip towards flashboard in said sealing valve buckle; The lip type part of this lips type rubber weather strip contacts with said flashboard, plays seal action.
Deviate to seal valve buckle in order to prevent lips type rubber weather strip; Utilize the elasticity extruding of lips type rubber weather strip 7 to be installed in the sealing valve buckle; The lip type part of lips type rubber weather strip closely cooperates through accurate Calculation and location and flashboard formation interference; Two vertical edges of said sealing valve buckle U font structure curve inwardly, and the angle between two vertical edges is the 40-60 degree.
In order to solve lock frame, sealing valve buckle and the sealing problem between the metope to be installed, between said lock frame, sealing valve buckle and installation metope, be provided with foam rubber stamping steel ribbon.
Said foam rubber stamping steel ribbon covers said lock frame and the seam crossing that seals valve buckle.
In said horizontal lock frame down, be provided with the bottom rubber weather strip.
Be fixed with claw on the lock frame of the present invention, said claw is installed in through chemical bolt and installs on the metope.
Gate valve of the present invention also comprises an actuator, and said actuator is installed in through support and installs on metope or the ground, is connected through a valve rod between said actuator and the flashboard, and the single suspension centre of employing is connected between said valve rod and the flashboard.
The cross section of said foam rubber stamping steel ribbon is a rectangle.
The length of said valve rod and the ratio of diameter are no more than 200, can not produce permanent deformation like this.
Owing to adopted design proposal as above, the lip type part and the flashboard of lips type rubber weather strip of the present invention form closely cooperating of interference, thereby have stoped the flowing medium of the inside and outside both direction of gate valve to pass through, and have realized two-way stagnant water effect.Between said lock frame, sealing valve buckle and installation metope, be provided with foam rubber stamping steel ribbon, also played the sealing effect simultaneously.Project organization of the present invention is simple, light and handy, intensity is high, and installation and maintenance are convenient, and two-way water stop is effective, and the resistance to compression safety coefficient is greater than 6, and the hydraulic pressure of adaptation can reach 10 heads.
Description of drawings:
Further specify the present invention below in conjunction with accompanying drawing and embodiment.
Fig. 1 is the structural representation of gate valve of the present invention
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the sealing configuration between flashboard of the present invention and the following horizontal lock frame.
Embodiment:
For technological means, creation characteristic that the present invention is realized, reach purpose and effect and be easy to understand and understand, below in conjunction with concrete diagram, further set forth the present invention.
Referring to Fig. 1 and Fig. 2, gate valve shown in Figure 1 comprises lock frame 3, and lock frame 3 adopts the bar section of stainless steel gang welding of C shape structures to form, and it comprises the two vertical lock frames 31 and the horizontal lock frame 32,33,34 in upper, middle and lower that laterally arrange.In, down 33,34 and two vertical lock frames 31 of horizontal lock frame define the valve port of gate valve of the present invention, after valve plate 5 was with this valve port Close All, this gate valve was in closed condition at this moment.
In two vertical lock frames 31, be set with guide rail 11 through stainless steel bolt, guide rail 11 is provided with guide groove 10, and flashboard 5 is stuck between the guide groove 10 of two guide rails 11, and with accurate location, flashboard 5 moves up and down along guide groove 10, realizes closing and opening of gate.Guide rail is that the non-maintaining engineering plastics of high tenacity selflubricating are processed, and friction factor is less than 0.2.
On two vertical lock frames 31, respectively be welded with claw 6 (claw quantity is by gate valve specification and the pressure decision of bearing); Claw 6 is fixed on through chemical bolt 14 and installs on the metope 15, just can whole lock frame 3 wall-attachments be installed in chemical bolt 15 through claw 6 and install on the metope 15.
In, down be fixed with 16, four sealings of sealing valve buckle valve buckle 16 on 33,34 and two vertical lock frames 31 of horizontal lock frame and constitute a square shape, sealing valve buckle 16 is between flashboard 5 and installation metope 15.Sealing valve buckle 16 openings of this U font structure are towards flashboard 5; In sealing valve buckle 16, lips type rubber weather strip 7 is installed; Deviate to seal valve buckle 16 in order to prevent lips type rubber weather strip 7; Utilize the elasticity extruding of lips type rubber weather strip 7 to be installed in sealing valve buckle 16; The lip type part of lips type rubber weather strip 7 closely cooperates through accurate Calculation and location and flashboard formation interference, and two vertical edges 161 of sealing valve buckle 16U font structure curve inwardly, and the angle between two vertical edges 161 is the 40-60 degree.Owing to form fitting tightly of interference between the lip type of lips type rubber weather strip 7 part and the flashboard 5, thereby stop the flowing medium of the inside and outside both direction of gate valve to pass through, realize two-way stagnant water effect.The rubber seal 7 of lips type is processed by Integratively formed rubber manufacturing process; Be used for gate 5, a left side and the sealing of right three sides; Guarantee the sealability of product, guaranteed the detection index of leakage rate≤0.02l/s.m under the condition of positive and negative bidirection press of gate 5.
