Description
Technical field
The utility model relates to extinguisher device field, specifically a kind of valve rod unitary tape stop screw type valve.
Background technique
Existing fire extinguisher screw type valve mechanism design is unreasonable, general employing spool combination, valve-rod combination, the split type assembling of gland nut, the deficiency of these assembling forms is that needs are multiple-sealed, assembly process is cumbersome, the assembly performance of product is not high, and sealability is not good, causes the maximum opening travel of valve to be restricted, fire extinguisher gas output reduces, and is delayed flame extinction time.
Summary of the invention
The purpose of this utility model is to provide valve rod unitary tape stop screw type valve.
It is unreasonable that the utility model will solve the design of existing fire extinguisher screw type valve mechanism, and need multiple-sealed, assembly process bothers, and assembly performance is not good, the problem that the maximum opening travel of valve is restricted.
The technical solution of the utility model is: a kind of valve rod unitary tape stop screw type valve, comprise valve body and valve rod, restraining groove is provided with in the middle part of described valve rod, described valve body is provided with stop screw hole, stop screw is provided with stop screw in hole, described valve rod lower end is provided with Sealing, described valve rod middle and lower part is provided with O RunddichtringO, and described O RunddichtringO is located between described restraining groove and Sealing, described valve body lower portion is provided with first passage, left side is provided with second channel, described first passage is vertical with second channel identical, the upper end of described first passage is provided with projection upwards, the lower end of described Sealing withstands in described projection, described Sealing, O RunddichtringO is integrated to be assemblied on described valve rod.
Preferably, described valve rod upper end is provided with working head, is fixed, fixed between described valve rod and described valve body by thread engagement mode by screw and described valve rod.
Preferably, the outside of described valve body lower end is provided with outside thread, the left part of described valve body and the outside being positioned at second channel is provided with outside thread.
Preferably, the right side of described valve body is provided with pressure-relieving device.
Preferably, described stop screw is two, radially symmetrical.
Preferably, described O RunddichtringO is at least two.
The beneficial effects of the utility model are: the utility model adopts Sealing, O RunddichtringO is integrated is assemblied on valve rod, easy to assembly, improve the assembly performance of product, solve multiple-sealed brought sealing problem further, valve rod is undertaken spacing by stop screw, thus ensure that the maximum opening travel of valve.
