Description

Folding stop valve

Technical Field

The utility model relates to a stop valve handle arm of force extension field specifically is a foldable stop valve.

Background

The stop valve, as the name suggests, the effect of stopping flow, two general passageways, one enters the liquid or admits air, and another goes out the liquid or gives vent to anger, rotates the valve rod, and the valve rod drives the gasket and supports tight play liquid passageway to accomplish and stop. Most of the existing stop valves adopt annular handles, so that the error touch is avoided, because if the stop valves are accidentally knocked, the circular handles cannot drive the valve rods to rotate, but the problem is caused, namely, the annular handles are large in size, large in circumferential occupied space, not like rod-shaped handles, but only in one direction, and if the size is not large, the arm of force is short, and the stop valves are relatively hard in rotation. Therefore, there is a need for a shut off valve with a ring handle that increases the length of the force arm.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a foldable stop valve to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: a folding stop valve comprises a valve body and a valve rod arranged on the valve body, wherein an annular handle is arranged on the valve rod;

and the valve rod is provided with a turnover mechanism which can turn over the handle to change the length of the force application arm of the valve rod.

Preferably, the turnover mechanism comprises a support rod which is horizontally arranged outwards at the upper end of the valve rod, a support block is fixed at the upper end of the support rod, convex blocks which are positioned at two sides of the support block are fixed in the circumferential direction of the handle, and the two convex blocks are rotatably connected with the support block through a pin shaft.

Preferably, the tail end of the supporting rod is fixed with a supporting cylinder sleeved on the valve rod.

Preferably, the outer end of the supporting cylinder is in threaded connection with a bolt of which the inner end abuts against the valve rod.

Preferably, a cross bar pointing to the support block is radially fixed on the inner cavity wall of the handle.

Compared with the prior art, the beneficial effects of the utility model are that:

1. in a normal state, the handle is arranged on the upper side of the valve rod, the handle is rotated, the handle drives the valve rod to rotate through the pin shaft, the supporting block and the lug, the valve body is opened and closed, the function of a common stop valve is achieved, when the handle is touched, the stress points to the circle center of the handle, the valve rod cannot be rotated, and the stop valve is safe;

2. when wanting laborsaving, the upset handle, the handle is wound to the outside of bracing piece, and the arm of force is equivalent to the diameter of handle and the length of bracing piece like this, and originally then uses the radius of handle as the arm of force, and the arm of force obviously increases like this, and it is lighter to rotate, moreover, foldable, and it is more convenient to use.

Drawings

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is a front view of the present invention;

fig. 3 is a top view of the handle and the support rod according to the present invention.

In the figure: 1 valve body, 11 valve rods, 12 handles, 2 support rods, 21 support blocks, 22 lugs, 23 support cylinders, 24 bolts and 25 cross rods.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 3, the present invention provides a technical solution of a folding stop valve: the utility model provides a foldable stop valve, includes valve body 1 and installs the valve rod 11 on valve body 1, and valve body 1 is the stop valve that commonly uses on the market, is provided with annular handle 12 on the valve rod 11.

The valve rod 11 is provided with a turnover mechanism which can make the handle 12 turn over to change the length of the force application arm of force to the valve rod 11, the turnover mechanism comprises a support rod 2 which is arranged at the upper end of the valve rod 11 and horizontally outwards, a supporting block 21 is fixed at the upper end of the supporting rod 2, a convex block 22 positioned at the two sides of the supporting block 21 is fixed at the circumference of the handle 12, and the two lugs 22 are rotatably connected with the supporting block 21 through a pin shaft, so that the lugs 22 drive the handle 12 to rotate around the supporting block 21, the pin shaft is spaced from the handle 12, therefore, the support handle 12 does not fall, the support cylinder 23 sleeved on the valve rod 11 is fixed at the tail end of the support rod 2, the stability of the support rod 2 is improved, the outer end of the support cylinder 23 is in threaded connection with a bolt 24 with the inner end abutting against the valve rod 11, the installation and the disassembly are convenient, the cross rod 25 pointing to the support block 21 is radially fixed on the inner cavity wall of the handle 12, and the force application rotation of the handle 12 is facilitated.

The working principle is as follows: normal state, the handle 12 is at the upside of valve rod 11, twist grip 12, handle 12 is through the round pin axle, supporting shoe 21 and lug 22 drive valve rod 11 and rotate, open and close valve body 1, the function of ordinary stop valve has, and when being touched, the directional centre of a circle of handle 12 of atress, valve rod 11 rotation can not be caused equally, it is safer, when wanting laborsaving, upset handle 12, handle 12 winds the outside of bracing piece 2, the arm of force is equivalent to handle 12's diameter and bracing piece 2's length in addition like this, and originally then be with handle 12's radius as the arm of force, the arm of force obviously increases like this, it is more relaxed to rotate, moreover, and is foldable, it is more convenient to use.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
