Problems solved by technology

[0002] The gate plate and valve stem of the fire valve are the most easily damaged parts. When an ordinary fire valve needs maintenance somewhere, it is necessary to close the main valve in the pipeline before maintenance. After the maintenance is completed, open the main valve of the pipeline to cause maintenance. Very inconvenient

Embodiment Construction

[0011] Such as figure 1 A replaceable upper-sealed fire valve shown includes a valve body 1, a control valve 2, and a side valve body 3. The control valve 2 is installed in the valve body 1, and includes a plastic sealing cover 4 connected in sequence, a switch wrench Head 5, bonnet 6, valve stem 7, gate plate 8; The side valve body 3 is installed on the outside of the valve body 1, and the inside is connected, including a side valve switch 12, a switch steering shaft 11 connected with the side valve switch 12, and The lower sealing plate 9 is connected with the switch steering shaft 11 through the pin 10, and the switch steering shaft 11 is installed below the gate plate 8.

[0012] When it is necessary to repair the valve stem or replace the gate plate, you only need to close the side valve switch to cut off the water source, carry out maintenance, and open the side valve switch after replacement; the design is simple in structure and easy to use.

[0013] The above is only...

Abstract

The invention discloses a replaceable upper-sealing type fire-fighting valve, comprising a valve body, a control valve and a side valve body, wherein the control valve is arranged in the valve body and comprises a plastic sealing cover, a switch wrench head, a valve cover, a valve rod and a gate plate which are connected in sequence; the side valve body is arranged at the outer side surface of the valve body and is communicated with the inside; the side valve body comprises a side valve switch, a switch steering shaft and a lower sealing plate; the switch steering shaft is connected with the side valve switch; the lower sealing plate is connected with the switch steering shaft by a pin; and the switch steering shaft is arranged under the gate plate. The replaceable upper-sealing type fire-fighting valve disclosed by the invention has the advantages that the maintenance can be finished by a switch pipeline of the switch steering shaft in the side wall of the valve body without closing a main valve, the use is convenient and the structural design is ingenious.

Description

technical field [0001] The invention relates to a fire-fighting valve, in particular to a replaceable upper-seal type fire-fighting valve. Background technique [0002] The gate plate and valve stem of the fire valve are the most easily damaged parts. When an ordinary fire valve needs maintenance somewhere, it is necessary to close the main valve in the pipeline before maintenance. After the maintenance is completed, open the main valve of the pipeline to cause maintenance. Very inconvenient. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the object of the present invention is to provide a replaceable upper sealing fire valve. [0004] In order to achieve the above purpose, the technical means adopted by the present invention are: a replaceable upper sealing fire valve, including a valve body, a control valve, and a side valve body. The control valve is installed in the valve body and includes plastic sealing Cover, switch wrench ...
