Abstract

The utility model relates to a fluid control valve and provides a reducing gate valve which is reasonable in structural design and can be directly connected between pipe fittings with different diameters. The reducing gate valve comprises a valve body, a valve cover, a gate opening and closing piece, a valve rod and an opening device, wherein the valve cover is arranged above the valve body; a water inlet end and a water outlet end which are connected with pipe fittings are arranged on the valve body along an axial direction; internal threads or external threads which are connected with the pipe fittings are formed on the water inlet end and the water outlet end; the gate opening and closing piece can be arranged between the water inlet end and the water outlet end in the valve body in a vertical lifting way; one end of the valve rod passes through the valve cover and is connected with the gate opening and closing piece; the opening device is arranged at a free end of the valve rod; and the water inlet end and the water outlet end of the valve body have different outer diameters and inter diameters.

Description

A kind of reducing gate valve

Technical field

The utility model relates to a kind of fluid control valve, particularly a kind of reducing gate valve.

Background technique

Existing gate valve mainly comprises valve body, valve gap, flashboard open-shut device, valve rod and opening device, and said valve gap is located at the valve body top, and said valve body upper edge axial component is provided with feed-water end and the waterexit end that is connected with pipe fitting; Said feed-water end is provided with internal thread or the outside thread that is connected with pipe fitting with the waterexit end, and said flashboard open-shut device can upper and lower up-down is located in the valve body between the said feed-water end and waterexit end, and said valve rod one end passes valve gap and is connected with the flashboard open-shut device; Said opening device is located on the free end of valve rod, plays a part to open or closing gate valve, during work; Drive the valve rod rotation through opening device and make the flashboard open-shut device do oscilaltion campaign, thus realization pipeline medium switch on or off the equal diameters of above-mentioned gate valve feed-water end and waterexit end; Only be applicable to and connect the pipe fitting that is positioned at the same diameter outside feed-water end and the waterexit end; During actual the use, normal appearance need be between the pipe fitting of different-diameter the attaching gate valve, the pipe connection fittings that need increase other during connection are realized being connected between different-diameter pipe fitting and the gate valve; Fitting operation is complicated; Time-consuming, effort have increased the junction point of pipeline, have improved installation and maintenance cost; Take pipeline location, make troubles to the workmen.

Summary of the invention

To the problems referred to above, the utility model proposes a kind of reasonable in design, can directly insert the reducing gate valve between the different-diameter pipe fitting.

For solving this technical problem; The utility model is taked following scheme: a kind of reducing gate valve, comprise valve body, valve gap, flashboard open-shut device, valve rod and opening device, and said valve gap is located at the valve body top; Valve body upper edge axial component is provided with feed-water end and the waterexit end that is connected with pipe fitting; Said feed-water end is provided with internal thread or the outside thread that is connected with pipe fitting with the waterexit end, and said flashboard open-shut device can upper and lower up-down is located in the valve body between the said feed-water end and waterexit end, and said valve rod one end passes valve gap and is connected with the flashboard open-shut device; Said opening device is located on the free end of valve rod, and the external diameter and the internal diameter of said valve inleting water end and waterexit end are all inequality.

Through adopting the aforementioned techniques scheme; The beneficial effect of the utility model is: the utility model reducing gate valve, and the external diameter and the internal diameter of said valve inleting water end and waterexit end are all inequality, have solved the problem that directly inserts gate valve between the different-diameter pipe fitting; Convenient installation and operation; Save the consumption and the construction operation amount of pipe fittings, reduced the junction point of pipeline, the bonding point of having reduced dielectric leakage.

Description of drawings

Fig. 1 is the utility model example structure schematic representation.

Embodiment

Combine accompanying drawing and specific embodiment that the utility model is further specified at present.

With reference to figure 1; Present embodiment discloses a kind of reducing gate valve; Comprise valve body 1, valve gap 2, pressure cap 3, flashboard open-shut device 4, valve rod 5 and open handwheel 6, said valve gap 2 is located at valve body 4 tops, and said pressure cap 3 is located at valve gap 2 tops; Said valve body 1 upper edge axial component is provided with the feed-water end 11 and waterexit end 12 that is connected with pipe fitting; Said feed-water end 11 is provided with internal thread or the outside thread that is connected with pipe fitting with waterexit end 12, and said flashboard open-shut device 4 can upper and lower up-down is located in the valve body 1 between the said feed-water end 11 and waterexit end 12, and said valve rod 5 one ends pass pressure cap 3 and are connected with flashboard open-shut device 4 with valve gap 2; Said unlatching handwheel 6 is located on the free end of valve rod 5, and said valve body 1 feed-water end 11 is all inequality with the external diameter and the internal diameter of waterexit end 12.

The utility model reducing gate valve; The external diameter and the internal diameter of said valve inleting water end and waterexit end are all inequality; Solved the problem that directly inserts gate valve between the different-diameter pipe fitting, convenient installation and operation, the consumption and the construction operation amount of having saved pipe fittings; Reduce the junction point of pipeline, reduced the bonding point of dielectric leakage.

The above record is merely the embodiment who utilizes this origination techniques content, anyly is familiar with modification, the variation that this creation of this art utilization is done, and all belongs to the claim of this creation opinion, and is not limited to embodiment announcement person.
