Abstract
The utility model discloses a closed type gate valve, which comprises a cylinder, a left connection board, a vane and a right connection board, wherein the left and the right connection boards are respectively arranged on the left interface and the right interface of the cylinder, and a slide rail cushion block is welded on the middle edges of the left and the right connection boards to form a chute whose three sides are completely sealed for adjusting the vane up and down. Nuts are respectively welded on holes at the two sides of the same face of the left connection board or the right connection board, and positioning screws are threaded through the nuts and the connecting boards to be corresponding to the vane. The gate valve is mainly installed on an air supply duct or a return air duct or an air exhaust duct of a ventilation system, is especially suitable for the technological ventilation in the industrial production, and has the advantages of small air quantity, excellent air tightness and convenient adjustment, compared with common air regulating valves.
Description
Technical field
The utility model relates to the closed type push-pull valve of building ventilation system and air-conditioning system.
Background technique
Building is the place that people live and work, modern humans nearly 4/5ths time is spent in building, architectural environment plays an important role to human longevity, working efficiency, quality of product and building ambient atmosphere environment, produce with scientific experiment environment has been proposed harsher requirement, constant temperature and humidity requirement as spinning and weaving workshop, the requirement that semi-conductor electronic device, computing chip manufacturing shop are controlled dust in the environment, aseptic requirement of environment such as antibiotic production and packing, aseptic experiment or the like.These mankind itself have caused the development of heating ventilation and air-conditioning technology to the requirement of environment requirement and production, scientific experiment, cause the attention of people to the building air conditioning ventilation system, various volume dampers are the indispensable component parts of air conditioner ventilating system, the main equilibrium adjusting air quantity that rises, the inleakage index of valve directly has influence on the equilibrium of energy saving, gas flow of system and adjusting, controls the leakage and the discharging of technology harmful gas effectively, and existing valve can not satisfy the usage requirement of this respect.
The model utility content
At the problem that prior art exists, the utility model aims to provide that a kind of inleakage is little, good leak tightness, push-pull valve easy to adjust.
The technical solution adopted in the utility model is:
A kind of closed type push-pull valve, comprise cylindrical shell, left connecting plate, blade and right connecting plate, described left and right connecting plate lays respectively on the left and right interface of cylindrical shell, left and right connecting plate middle edge welding slide rail cushion block, forming one supplies three of the blade up-down adjustment to seal chute fully, a left side connecting plate or right connecting plate are welded with nut with the both sides of one side respectively at the place of boxing out, and positioning screwn passes nut and connecting plate corresponding to blade.
Be superimposed with wing nut on the described nut.
Described screw is a hexagon socket cap head screw.
Described blade dimensions is greater than the interface size.
Rounded, the square or rectangle in described cylindrical shell cross section.
The top margin of described left and right connecting plate and blade is equipped with the bending part.
The utility model mainly is installed on the sending of ventilation system, the return air duct or on the exhaust duct, the industrial technology of particularly suitable is ventilated, the main equilibrium adjusting air quantity that plays a part, by pulling blade adjustments valve body vent area, when arriving the precalculated position, the positioning screwn of tightening both sides is with vanes fixed, tightening wing nut again plays a part to prevent to become flexible to blade, can reduce system energy consumption, reduce the leakage of the toxic gas that is produced when producing, solved the problem that general volume damper cann't be solved.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a side view of the present utility model;
Fig. 3 is the enlarged diagram of I shown in Figure 1 portion.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of reference numerals is as follows:
The left connecting plate of 1---cylindrical shell 2---
The right connecting plate of 3---blades 4---
5---slide rail cushion block 6---nut
7---wing nut 8---hexagon socket cap head screw
As shown in Figures 1 to 3, this push-pull valve is mainly by cylindrical shell 1, left side connecting plate 2, blade 3 and right connecting plate 4 constitute, a left side, right connecting plate lays respectively at the left side of cylindrical shell 1, on the right interface, edge joint weld connects slide rail cushion block 5 in the middle of it, forming one supplies three of the blade up-down adjustment to seal chute fully, to reduce the leakage rate of valve itself, right connecting plate 4 is welded with nut 6 with the both sides of one side respectively at the place of boxing out, be superimposed with wing nut 7 on the nut 6, hexagon socket cap head screw 8 passes wing nut 7, nut 6 and right connecting plate 4 are corresponding to blade 3, the width of blade 3 is greater than the cylindrical shell interface width, when closing, blade can be in complete sealing state, inleakage when reducing valve closing during adjusting vane 3, is tightened hexagon socket cap head screw 8, pass right connecting plate 4, make blade 3 at the chute internal fixation, tighten wing nut 7 again, prevent blade 3 loosening landings.
Above-mentioned cylindrical shell can be done squarely or rectangle according to actual, and its structure is the interface shape difference, and other structure, regulative modes with circular push-pull valve are all identical.
The utility model is not limited to above-mentioned preferred forms, and anyone can draw other various forms of products under enlightenment of the present invention.Though but on its shape or structure, do any variation, every identical with the utility model or akin technological scheme is all within its protection domain.
Claims (6)
1, a kind of closed type push-pull valve, it is characterized in that, comprise cylindrical shell, left connecting plate, blade and right connecting plate, described left and right connecting plate lays respectively on the left and right interface of cylindrical shell, left and right connecting plate middle edge welding slide rail cushion block, form for the blade up-down adjustment three and seal chute fully, left connecting plate or right connecting plate are welded with nut with the both sides of one side respectively at the place of boxing out, and positioning screwn passes nut and connecting plate corresponding to blade.
