Abstract
The utility model discloses a hard sealing gate valve swing arm structure of stainless steel rising stem (RS. ), including the valve rod, the valve rod upper end is equipped with the counter bore and rotates and install afterburning pole, and fixed mounting has a spring in the counter bore, and the spring housing is on afterburning pole, and fixed connection is on counter bore bottom and afterburning pole respectively at the both ends of spring, and there is turning handle the upper end of afterburning pole through set barrel casing, and through key tooth slidable mounting between sleeve and the afterburning pole, the up end of afterburning pole is equipped with screw and spiral shell and has closed the baffle, and the valve rod up end is equipped with bayonet socket, afterburning pole pair and answers the position to be equipped with the fixture block to coordinate with the bayonet socket. The utility model discloses structural design is simple and ingenious, makes convenient to use, and when not using, the sleeve drives the handle and is upspring by the spring, the unable valve rod that rotates, and during the use, push handle casing, convenient and practical.
Description
Technical field:
This utility model relates to Outside screw stem rising through handwheel type gate valve field, particularly a kind of rustless steel rising stem (RS.) hard seal gate valve swing arm structure.
Background technology:
The opening and closing element of Outside screw stem rising through handwheel type gate valve is flashboard, and the direction of motion of flashboard is perpendicular with flow direction, and gate valve can only make standard-sized sheet and fully closed, it is impossible to makes adjustments and throttles.
The shortcoming of Outside screw stem rising through handwheel type gate valve is as follows:
Easily cause erosion and scratch between sealing surface, keep in repair relatively difficult；Overall dimensions is relatively big, opens and needs certain space, and opening/closing time is long；Structure is more complicated.
Utility model content:
The purpose of this utility model is to solve the deficiencies in the prior art, and a kind of rustless steel rising stem (RS.) hard seal gate valve swing arm structure provided.
The technical solution adopted in the utility model is:
Rustless steel rising stem (RS.) hard seal gate valve swing arm structure, including valve rod, it is characterized in that: described valve rod upper end is provided with counterbore and is rotatablely equipped with boosting-rod, spring it is installed with in counterbore, spring is placed on boosting-rod, and the two ends of spring are respectively fixedly connected with on counterbore base and boosting-rod, the upper end of boosting-rod is cased with turning handle by sleeve, it is slidably installed by key tooth between sleeve and boosting-rod, the upper surface of boosting-rod is provided with screw and is screwed with baffle plate, and valve rod upper surface is provided with bayonet socket, boosting-rod correspondence position is provided with fixture block and bayonet fittings.
Described rustless steel rising stem (RS.) hard seal gate valve swing arm structure, it is characterised in that: described boosting-rod sidewall is provided with key tooth, is slidably matched with sleeve.
Compared with prior art, the beneficial effects of the utility model are:
The design of this utility model structure is simple and ingenious, manufactures easy to use, and when not in use, sleeve band fixed handle is upspring by spring, it is impossible to rotation valve rod, during use, and lower pressure handle casing, convenient and practical.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
Below in conjunction with the accompanying drawings, by embodiment, this utility model is described in further detail:
Rustless steel rising stem (RS.) hard seal gate valve swing arm structure, including valve rod 1, valve rod 1 upper end is provided with counterbore and is rotatablely equipped with boosting-rod 2, spring 3 it is installed with in counterbore, spring 3 is placed on boosting-rod 2, and the two ends of spring 3 are respectively fixedly connected with on counterbore base and boosting-rod 2, the upper end of boosting-rod 2 is cased with turning handle 5 by sleeve 4, it is slidably installed by key tooth 6 between sleeve 4 and boosting-rod 2, the upper surface of boosting-rod 2 is provided with screw and is screwed with baffle plate 7, and valve rod 1 upper surface is provided with bayonet socket 8, boosting-rod 2 correspondence position is provided with fixture block 9 and coordinates with bayonet socket 8.
Above-described embodiment is only preferably embodiment of the present utility model, and in addition, this utility model can also have other implementations.It should be noted that on the premise of conceiving without departing from this utility model, within any conspicuously improved and modification all should fall into protection domain of the present utility model.
