[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0020] The specific embodiments are given below

[0021] Please refer to Figures 1-4 The pressure gauge tube fracture blowout water stop valve of the embodiment includes a main body mechanism 1, the top of the main body mechanism 1 is provided with a connecting mechanism 2, and the connecting mechanism 2 is provided with a sealing mechanism 3.

[0022] The main body mechanism 1 includes a valve body lower end cover 101, and the top of the valve body lower end cover 101 is provided with a valve body upper end cover 102.

[0023] The valve body lower end cover 101 and the valve body upper end cover 102 are symmetrically distributed, and the valve body upper end cover 102 is located at the top of the valve body lower end cover 101.

[0024] The connecting mechanism 2 includes a valve barrel 201, and the valve barrel 201 is provided with a conical suspension plug 202.

[0025] The bottom of the valve barrel 201 is fixedly connected with the valve body lower end cover 101, and the top of the valve barrel 201 is fixedly connected with the valve body upper end cover 102.

[0026] The sealing mechanism 3 includes a lower cover rubber ring 301, and the top of the lower cover rubber ring 301 is provided with an upper cover rubber ring 302.

[0027] The lower cover rubber ring 301 and the upper cover rubber ring 302 are fixedly connected with the valve body lower end cover 101 and the valve body upper end cover 102 respectively.

[0028] Working principle: 1, water pump operation flow through the valve body push valve cylinder 201 in the suspension plug in the cylinder suspension, because the flow rate is slow, so that the suspension plug in the valve cylinder 201 suspension without affecting the transmission of pressure, and then through the pressure gauge conduit to the pressure gauge, pressure gauge feedback pump actual operating pressure.

[0029] 2, when the pressure gauge conduit is broken at any position, through the valve body pipe flow rate increases rapidly, flow increases, at the same time, because the flow rate increases rapidly, the flow increases rapidly push the valve cylinder 201 in the suspension plug to the valve body on the vertex, the suspension plug is the upper circle lower cone type, because of the effect of pressure, the suspension plug on the plane and the valve body on the water outlet is blocked, and the water with pressure in the pipeline is blocked.

[0030] The above-mentioned embodiments are only preferred embodiments of the present application, and cannot be used to limit the scope of protection of the present application. Any non-essential changes and replacements made by those skilled in the art on the basis of the present application shall fall within the scope of protection of the present application.
