Abstract
The square pipe valve is integrally manufactured by using silicon rubber with certain elasticity and good stability, one part is the whole valve body, and the square pipe valve is simple in structure, easy to manufacture, free of rusting, corrosion-resistant, low in cost and easy to popularize.
Description
Technical Field
The invention relates to a mine self-rescuer, in particular to a quadrilateral square pipe valve.
Background
The personnel in the underground coal mine must wear a self-rescuer; the mine self-rescuer can play a role in respiratory protection, in order to prevent the nasal cavity from inhaling toxic and harmful gases, a nasal clip is used for clamping the nasal cavity, a bite block in a respiratory mouthpiece is clenched, and clean air in the oral cavity respiratory self-rescuer is used; the respiratory gas can be exchanged only when reaching the air exchanging valve through the gas pipeline, most of the existing valve bodies have complex structures and are difficult to manufacture, and particularly, steel parts such as a check valve plate, a valve body pin shaft, a valve core, a spring and the like are easy to rust and corrode by corrosive substances.
Disclosure of Invention
The invention aims to solve the problems and provides a quadrilateral square pipe valve which is easy to manufacture, does not rust and is corrosion-resistant.
In order to achieve the purpose, the invention adopts the technical scheme that: a square pipe valve with a square shape comprises a square pipe with a valve, a valve edge is integrally connected with the valve, a switch edge is parallel to the valve edge, two sides are seamlessly connected with two ends of the valve edge and the switch edge at right angles, and an arc-shaped groove is formed in the connecting part of the valve and the valve edge.
Furthermore, the height of the valve is smaller than the height of the valve edge and the height of the switch edge, the length of the valve is larger than the length of the side edge, the valve forms an angle of 0 degree with the valve edge when being completely opened, and the valve forms an angle of 45 degrees with the switch edge when being completely closed.
Furthermore, when the valve is completely opened, one end of the valve connected with the valve edge is an air inlet, and the other end of the valve is an air outlet.
Furthermore, the square pipe valve is integrally made of silicon rubber which has certain elasticity, good stability and corrosion resistance, and the natural static state of the valve is a closed state.
Advantageous effects
The square pipe valve is integrally manufactured by using silicon rubber with certain elasticity and good stability, one part is the whole valve body, and the square pipe valve is simple in structure, easy to manufacture, free of rusting, corrosion-resistant, low in cost and easy to popularize.
Drawings
Figure 1 is a schematic cross-sectional view of the structure of the present invention,
figure 2 is a front view of the invention.
Detailed Description
The invention will be further explained with reference to the drawings.
As can be seen from the attached drawings 1 and 2, the quadrangular square pipe valve is integrally made of silicon rubber with certain elasticity, good stability and corrosion resistance, a valve (5) is arranged in the quadrangular square pipe, a valve edge (1) is integrally connected with the valve (5), a switch edge (2) is parallel to the valve edge (1), two side edges (3) are connected with two ends of the valve edge (1) and the switch edge (2) in a right angle manner, and an arc-shaped groove (4) is arranged at the connecting part of the valve (5) and the valve edge (1); the height of the valve (5) is smaller than the height of the valve edge (1) and the height of the switch edge (2), so that the valve (5) can freely move in the square tube, the length of the valve (5) is larger than that of the side edge (3), the valve (5) forms an angle of 0 degree with the valve edge (1) when being completely opened, the valve (5) forms an angle of 45 degrees with the switch edge (2) when being completely closed, one end of the valve (5) connected with the valve edge (1) is an air inlet when the valve (5) is completely opened, the other end of the valve (5) is an air outlet, and the natural static state of the valve (5) is a closed state; when the air pressure of the air inlet is higher than that of the air outlet in use, the arc-shaped groove (4) at the connecting part of the valve (5) and the valve edge (1) is firstly stressed and bent, and the valve (5) can be opened to pass through by air; when the pressure of the air inlet and the air outlet is balanced, the valve (5) is restored to a natural static closing state; when the air pressure of the air inlet is lower than that of the air outlet, the air pressure presses the valve (5) on the switch edge (2) to prevent air from passing through, and the check valve is used.
It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and all other embodiments obtained by those skilled in the art without any inventive work are within the scope of the present invention.
Claims (2)
1. A quadrilateral square pipe valve for a mine self-rescuer comprises a quadrilateral square pipe, wherein the height of a valve (5) is smaller than the heights of a valve edge (1) and a switch edge (2), the length of the valve (5) is larger than that of a side edge (3), the valve (5) forms an angle of 0 degree with the valve edge (1) when being completely opened, the valve (5) forms an angle of 45 degrees with the switch edge (2) when being completely closed, one end of the valve (5) connected with the valve edge (1) is an air inlet when the valve (5) is completely opened, and the other end of the valve (5) is an air outlet; there is valve (5) in the square pipe of quadrangle, with valve (5) body coupling be valve limit (1), parallel with valve limit (1) be switch limit (2), be right angle seamless connection with the both ends of valve limit (1) and switch limit (2) two sides (3), valve (5) have arc recess (4) with the junction of valve limit (1), the atmospheric pressure of air inlet when being higher than the atmospheric pressure of gas outlet, arc recess (4) the position of the junction of valve (5) and valve limit (1) is crooked at first atress, quadrangle square pipe valve use the integrative manufacturing of silicon rubber that has certain elasticity, a part is whole valve body both.
2. The quadrilateral square tube valve for the mine self-rescuer according to claim 1, which is characterized in that; the natural rest state of the valve (5) is the closed state.
